Description

High-voltage circuit breaker for electrodes and use of a high-voltage circuit breaker

The invention relates to a high-voltage circuit breaker for poles, having interrupting units which are connected in series and are mechanically stable to one another, and to the use thereof. The interruption unit is arranged on at least one carrier.

High-voltage circuit breakers, in particular for switching voltages of up to 1200kV and/or currents of up to several hundred amperes, are known, for example, from DE 19601053C 1. The outdoor high-voltage circuit breaker comprises two interruption units for the poles, which are arranged in the composite insulator housing, respectively. The two breaking units are connected in series in turn and are arranged along a common longitudinal axis together with the associated composite insulator housing. Two composite insulator housings, each with an interruption unit, are arranged on a pole or a support and are connected to each other by a steering gear. The outdoor high voltage power switch has a T-shaped structure with two arms, wherein each arm comprises one interruption unit.

Gas-insulated switching units, in particular gas-insulated switching units having rated-current contacts and main arcing contacts as switching contacts, are used for switching high voltages and currents. The composite insulator housing, in which the interruption units are respectively present, is filled with a switching and/or insulating gas, in particular SF₆. For switching between and between switching contactsAnd a pressure of the switch and/or the insulating gas in the composite insulator housing is one bar or more. The composite insulator housing has an airtight structure and has excellent gas insulation properties. The gas insulation must be stable for a long time, especially over 30 years. Switching gases, e.g. SF₆Is harmful to the environment, especially to the climate, and a leakage rate of less than 0.1% must be stably secured for a long time for the composite insulator housing having the interruption unit.

In order to avoid weather-hazardous switches and/or insulating gases, vacuum tubes are used in particular as interruption units. The vacuum tube is constructed for switching voltages of up to several tens of kV. In high switching powers, in particular switching voltages much higher than 100kV, a plurality of vacuum tubes are connected in series one after the other. The vacuum tube may be provided directly with a weather-proof insulation or arranged in the composite insulator housing. The number of serially connected, sequentially arranged interruption units and thus the maximally switchable power or voltage is limited by the mechanical properties of the high-voltage power switch. Environmental influences, such as wind, can lead to high mechanical loads on the arms of the T-shaped high-voltage circuit breaker.

The length of the arm increases with the number of the interrupting units arranged in sequence, and the mechanical components, such as the pole, the steering gear and the connecting element, can be implemented intensively for ensuring a high reliability and mechanical stability of the high-voltage circuit breaker over time. High costs, higher material costs and/or shorter maintenance intervals are associated therewith. As the length of the arms of the T-shaped high-voltage circuit breaker increases, the mechanical load, in particular on the end of the arm facing away from the pole, increases strongly, and further lengthening of the arms for higher voltage levels may not be possible. The space consumption of the high-voltage circuit breaker increases with the length of the arm of the T-shaped high-voltage circuit breaker, which leads to higher costs.

The object of the present invention is to specify a high-voltage circuit breaker for an electrode and its use, which avoids the above-mentioned problems. The object is in particular to provide a simple, compact and inexpensive high-voltage circuit breaker which is mechanically stable, environmentally friendly and durable in operation and can be designed for high voltage levels.

According to the invention, the technical problem described is solved by a high-voltage circuit breaker for an electrode having the features of claim 1 and/or by the use of a high-voltage circuit breaker according to claim 11. Advantageous embodiments of the high-voltage circuit breaker for an electrode and its use according to the invention are specified in the dependent claims. The contents of the independent claims can be combined with one another and with the features of the dependent claims, and the features of the dependent claims can be combined with one another.

The high voltage power switch for an electrode according to the present invention includes interrupting units, which are connected in series and are mechanically stably connected to each other. The interruption unit is arranged on at least one carrier. The interruption units are arranged on different axes.

By arranging a plurality of interruption units on different axes, more interruption units can be arranged compactly in the narrowest space. The interruption unit can be arranged close to a point, in particular the intersection point of the shafts, wherein the mechanical support at this point results in a mechanically stable, compact high-voltage circuit breaker for high voltage levels. More than just two interruption units can be arranged stably, thus increasing the voltage to be switched with respect to prior art high voltage power switches when connected in series.

In particular in outdoor switchgear, the interruption unit can comprise a vacuum tube and/or a gas-filled power switch, which in particular has rated and main arcing contacts. The overall switching voltage of the high-voltage circuit breaker can be increased by the higher possible number of series-connected interruption units, in particular the interruption unit with the largest switching voltage. In particular in vacuum tubes which are manufactured in large numbers only with switching voltages of, for example, up to 35kV, the arrangement according to the invention of the interruption units not only in succession on one axis, but also on different axes, for example circumferentially, at the same distance from one another enables an increase in the total switching voltage of the high-voltage circuit breaker. In a gas-filled circuit breaker, in particular with a rated and main arcing contact, the arrangement according to the invention of the interruption unit enables high switching voltages of up to 1200kV and more.

The interruption unit may be arranged in a plane, in particular a plane substantially parallel to the substrate. This makes it possible to achieve a compact, inexpensive design of the high-voltage circuit breaker according to the invention, which is mechanically stable and can be designed for high voltage levels. In the use of switching gases, e.g. SF, which are not harmful to the environment₆And/or when using gas-filled or gas-insulated circuit breakers, in particular with rated and main arcing contacts, for example when using clean air for switching voltages of, in particular, a few hundred kV, which are lower, durable, environmentally friendly, high-voltage circuit breakers for high voltage levels can be produced. The arrangement of the interruption unit in one plane enables good insulation with respect to a substrate with sufficient spacing, i.e. ground potential and/or ground on which the high-voltage circuit breaker is arranged or in which the high-voltage circuit breaker is anchored in the base. The insulating support for the high-voltage circuit breaker can be designed to be of a minimum height, since all the interruption units can be arranged in the minimum height or in the minimum distance from the ground for the voltage level to be switched. The danger of maintenance personnel passing the arc over the height of the base can be avoided or reduced.

The respective at least two interruption units may be arranged on a common longitudinal axis. Different longitudinal axes may be included, the longitudinal axes intersecting at a point, particularly at an angle of 90 degrees between the longitudinal axes. Thereby, a high number of interruption units may be arranged in series connection with good electrical insulation between the interruption units in areas that are not electrically conductive through the circuit connection. In particular in the case of four interruption units arranged on two shafts (which enclose an angle of 90 degrees, for example with insulating support brackets arranged centrally on the intersection point, for a mechanically stable arrangement even in the case of harmful environmental influences, for example in the case of a storm), the interruption units can be electrically well insulated by the mutual distance in the region which is not electrically connected by the circuit connection. The axes may for example form a cross and the interruption units have the same distance from each other along the axes, the distance between adjacent interruption units on different axes being equal to the distance between interruption units on a common axis.

The interruption units may be arranged such that the longitudinal axes of the interruption units are star-shaped, in particular have a common point of intersection, and/or the longitudinal axes of the interruption units are arranged crosswise. In a common intersection point of the shafts, for example in a star shape or a cross shape, the largest number of interruption units can be arranged on a circumference in one plane with in particular the same distance from one another. In particular, the use of insulating support brackets arranged in a common intersection point results in a particularly compact, inexpensive structure for achieving high mechanical stability, which has a high number of interruption units, i.e. a high possible switching voltage, and good insulation of the interruption units from one another by the ambient air in the region of no circuit connection.

The series connection of the interruption units can be realized by means of cables and/or rails, in particular made of copper and/or aluminum, in particular with at least one connection housing between the interruption units, which can be arranged on the free ends of the interruption units and/or which does not have a mechanical load-bearing function for the interruption units. Arcing is avoided by the insulation of the cables and/or rails via the connection housing, and a compact arrangement of the interruption units with a series connection is possible. The interruption unit and the cable and/or rail can be electrically insulated to the outside, in particular by an insulator, whereby, in the case of high voltages and/or currents to be switched, a small spatial distance between the interruption unit and the cable and/or rail is possible.

The high-voltage circuit breaker according to the invention can comprise exactly one carrier, in particular in the form of a column and/or standing vertically. The carrier can have a support insulator or a plurality of support insulators, in particular connected by flanges, wherein the support insulators comprise in particular ceramics, silicone and/or composite materials. The carrier can comprise a base housing, in particular made of metal. The carrier can furthermore comprise a carrier support, which is in particular made of metal. As a result, a high mechanical stability can be achieved with little effort or cost and with good electrical insulation of the interruption unit with respect to the substrate or base.

The interruption unit arranged on the at least one carrier can be mechanically fixed, in particular directly and/or via an insulator and/or a connecting housing and/or a housing of the interruption unit in which the interruption unit is arranged, on the carrier and/or on a transmission housing arranged on the carrier. In this way, good mechanical stability of the high-voltage circuit breaker can be achieved without good electrical insulation of the interruption cells from one another and from the substrate in the region in which the interruption cells are not electrically connected in series.

It may comprise a drive, in particular a drive arranged laterally on the carrier, and/or it may comprise elements of a kinematic chain, in particular a steering gear and/or a switch lever, for transmitting a driving movement of the drive to the interruption unit, in particular for switching the interruption unit at the same time. In the case of switching, the driver can simply, inexpensively and reliably provide the kinetic energy, which is transmitted via the elements of the kinematic chain to the movable contact pieces of the switching contacts of the interruption unit.

The insulating device, in particular the insulator and/or the support insulator, can be filled with an insulating gas, in particular clean air, which has in particular a pressure in the range of the ambient pressure of the high-voltage circuit breaker. Good electrical insulation can be achieved when using an insulating gas, for example clean air, in particular without harmful environmental influences, for example without endangering the climate. In the case of using a pressure in the range of the pressure of the ambient air, the seal is subjected to little load, seals stably for a long time, and can be designed simply and inexpensively.

The use according to the invention of a high-voltage circuit breaker for poles comprises the use in outdoor circuit breakers, in particular in outdoor circuit breakers with three poles. As a result, switching of, for example, electrical consumers, power networks and/or current generators can be realized inexpensively, simply, compactly and reliably outside long time periods, at high voltage levels of, for example, up to 1200kV or more, and in particular for three phases or with three poles.

The advantages of the application according to the invention of the high-voltage circuit breaker according to claim 11 are similar to the previously described advantages of the high-voltage circuit breaker according to claim 1 for poles and vice versa.

Subsequently, embodiments of the present invention are schematically illustrated in fig. 1 to 3 and subsequently described in detail.

Fig. 1 shows a high-voltage circuit breaker 1 according to the invention for an electrode in a sectional view from the side. The four interruption units of the exemplary embodiment are each arranged in a housing 10, two

interruption units

2, 3 being shown in fig. 1. The housing 10 is designed in the form of a jacket and/or an insulator housing, for example, in the form of a hollow cylinder, in particular made of silicone, composite material and/or ceramic, and protects the

interruption units

2, 3 from the weather. Fig. 1 shows vacuum tubes as

interruption units

2, 3. The housing 10 is filled in particular with an insulating gas, for example clean air. The pressure of the insulating gas is in the range of the ambient pressure, so that no additional, complex gas seals or pressure-resistant housings have to be used.

Alternatively or additionally to vacuum tubes, gas-insulated circuit breakers, in particular with a rated contact and a main arcing contact, may also be used. In this case, for example, clean air and/or SF may be used, in particular at pressures of more than 1 bar₆Used as switching gas. The housing 10 can be designed as ribbed, in particular as annular ribbed, for increasing the dielectric strength in the longitudinal direction on the outer surface. The electrical interface 12 is provided for electrically contacting the

interruption units

2, 3 and is guided out of the housing 10, for example in a gas-tight manner, in particular at the end of the housing 10. The

interruption units

2, 3 have at least one switching contact with at least one movable contact piece and in particular with a fixed contact piece. The contact piece is electrically connected to the interface, and the movable contact piece is mounted so as to be movable, is connected to an element of the kinematic chain 17, in particular a switching lever, and is guided out of the housing 10 in a particularly gas-tight manner.

The housing 10 with the

interruption units

2, 3 is mechanically stably connected to the transmission housing 8, in particular by a connecting housing 11 and the insulating body 9, in particular by flanges. The insulating body 9 is, for example, of hollow-cylindrical design, in particular made of silicone, composite material and/or ceramic. The insulating body 9 is configured as a rib, in particular as an annular rib, for increasing the dielectric strength in the longitudinal direction on the outer surface. The connection housing 11, the insulator 9 and/or the gear housing 8 are filled with an insulating gas, for example clean air. The pressure of the insulating gas can be in the range of the ambient pressure, so that no additional, complex gas seals or pressure-resistant housings have to be used.

The two

interruption units

2, 3 shown in fig. 1 are each arranged coaxially in the housing 10 and, together with the insulator 9, on a common longitudinal axis 23, the longitudinal axis 23 extending in particular centrally through the connecting housing 11 and the transmission housing 8. The gear housing 8 is arranged on the carrier 6 in a mechanically stable manner, in particular centered on a common vertical axis. The carrier 6 comprises, for example, a carrier bracket 18, which is firmly anchored in the substrate or ground, in particular by means of a foundation, and is constructed, in particular, in the form of an H-shaped steel carrier. On the carrier support 18, for example, a base housing 15 is arranged, which is made of sheet metal and/or plastic, for example, and on which a drive 16 is fastened, for example, laterally. The drive 16 is, for example, an electric motor and/or a spring-loaded drive and may comprise further elements, such as, for example, transmission components, coupling elements, control or regulating elements, sensors and/or communication elements.

At least one supporting insulator 13, which may be designed in multiple parts, is arranged, for example, on the carrier support 18 and/or the base housing 15, wherein the parts are connected to one another, in particular by means of flanges, for example made of metal, in particular by means of screws, rivets, soldering and/or fusion welding. The transmission housing 8 is arranged on a support insulator 13. Viewed from one side, the high-voltage circuit breaker 1 has a T-shaped structure with a particularly cylindrical carrier 6, which stands vertically upward, substantially perpendicular to the base. The two arms of the sides of the T-shaped structure (on the left and right of the carrier 6) comprise, starting from the left, a first interruption unit 2 in a housing 10, which is mechanically stably fastened to a connection housing 11, to an insulator 9, to a transmission housing 8, to an insulator 9 on the right, to a connection housing 11 on the right, and to a housing 10 on the right with a second interruption unit 3.

The first interrupter unit 2, the connecting housing 11, the insulator 9, the gear housing 8, the right-hand insulator 9, the right-hand connecting housing 11 and the right-hand housing 10 with the second interrupter unit 3, which are arranged coaxially in the housing 10, are arranged coaxially on a common shaft, in particular a longitudinal shaft 23. The shaft 23 is horizontal, substantially parallel to the substrate on which the high voltage power switch 1 is mounted. In particular, the elements of the kinematic chain 17 are arranged movably inside the left housing 10, the left connecting housing 11, the left insulator 9, the transmission housing 8, the right insulator 9, the right connecting housing 11 and the right housing 10, and from the transmission housing 8, in particular through the supporting insulator 13 and/or the supporting insulator 13 with the flange 14 and the inside of the base housing 15, and are connected to the

interruption units

2, 3 and the drive 16.

The switching movement is provided when the switching drive 16, for example a spring-loaded drive and/or an electric motor, and is transmitted from the drive 16 to the interruption unit, in particular all movable contacts of the interruption unit, via the elements of the kinematic chain 17. For example, the steering gear 7, the switching lever, the lever, and/or other elements of the kinematic chain 17 are provided here for transmitting the switching movement to all the interruption units, in particular simultaneously or offset in time, and a change in the switching speed and/or switching direction can be achieved. This results in a movement characteristic of the movable contact piece, which is required for switching, in particular switching on and/or off, the high-voltage circuit breaker 1.

Fig. 2 shows the high-voltage circuit breaker 1 of fig. 1 in a schematic sectional view from above. Fig. 1 shows the high-voltage circuit breaker 1 of fig. 2 from the left. In the embodiment of the drawing of the high-voltage circuit breaker 1 according to the invention for an electrode, four

interruption units

2, 3, 4, 5 are connected in series and are arranged in pairs on two intersecting

axes

23, 24. The

axes

23, 24 are arranged in a plane, in particular a horizontal plane substantially parallel to the base of the high-voltage circuit breaker 1. The high-voltage circuit breaker 1 has a cross-like shape when viewed from above, with the sides of the same length. The outer ends of the

interruption units

2, 3, 4, 5 form the corners of a square. The intersecting axes 23, 24 form the diagonals of the square. The

axes

23 and 24 intersect at a right angle, i.e. at an angle of 90 degrees. In the intersection point, a gear housing 8 with a steering gear 7 is arranged.

The gear housing 8 with the steering gear 7 is arranged centrally on the, in particular, cylindrical carrier 6, as shown in fig. 1. The high-voltage circuit breaker 1 consists of two T-shaped structures which intersect at an angle of 90 degrees and have identical, common or identical cylindrical carriers 6. The arms of the T-shaped structure are directed away from the carrier 6 in four different directions, wherein adjacent directions enclose an angle of 90 degrees, respectively. On the ends of the arms,

interruption units

2, 3, 4, 5 are arranged, respectively. All the

interruption units

2, 3, 4, 5 are connected to a transmission housing 8 via a common steering gear 7, wherein an insulator 9 and a connecting housing 11 are arranged between the transmission housing 8 and the

respective interruption unit

As shown in the exemplary embodiment of fig. 2, the

interruption units

2, 3, 4, 5 are connected to one another in series via electrical connection elements 22 (e.g., cables and/or rails made of copper and/or aluminum, in particular). The electrical connection element 22 is arranged in the connection housing 11. For this purpose, the connection housing 11 is designed such that, in each case along the longitudinal axis of the connection housing 11, a connecting element 22 is arranged in particular inside the connection housing 11, which connecting element connects two

adjacent interruption units

2, 3, 4, 5 to one another. For example, substantially parallel to or identical to the outer sides of the square formed by the

interruption units

2, 3, 4, 5 on the corners. The connection housing 11 is formed, for example, by an insulator, in particular an insulator made of ceramic, silicone and/or a composite material, which comprises, for example, a ribbed outer surface for good external electrical insulation. The connection housing 11 is filled, for example, with an insulating gas, for example clean air, or directly surrounds the electrical connection element 22. The electrical connection element 22 with the connection housing 11 can also be embodied in accordance with the type of cable to be encased or conductor rails to be encased.

The first interruption unit 2 has, on the side facing outward, an electrical interface 12 for, for example, an electrical generator, a consumer and/or a power grid, which can be switched on and/or off by means of the high-voltage circuit breaker 1. On the opposite side of the interruption unit 2, electrical connection elements 22 are connected, which electrically connect the first interruption unit 2 with the adjacent second interruption unit 3. The connecting element 22 is arranged in the connecting housing 11 between the first and

second interruption units

2, 3. The connecting housing 11 is arranged with its ends between the

interruption unit

2, 3 or its housing 10 and the insulator 9, which mechanically fixes the interruption unit to the steering gear 7 or the gear housing 8. The connecting element 22 is electrically connected to the second interruption unit 3 on the side pointing in the direction of the insulator 9 or the steering gear 7.

On the opposite side of the second interruption unit 3, electrical connection elements 22 are connected, which electrically connect the second interruption unit 3 with a third interruption unit 4, which is arranged adjacent to the second interruption unit 3. The connecting element 22 is arranged in the connecting housing 11 between the second and third interruption units 3, 4. The connecting housing 11 is arranged with its ends on the interruption units 3, 4, respectively on the side opposite the side of the interruption units 3, 4 or of its housing 10 pointing in the direction of the insulator 9 or the transmission housing 8.

On the side of the interruption unit 4 or its housing 10 pointing in the direction of the insulator 9 or the transmission housing 8, the third interruption unit 4 is connected to the adjacent fourth interruption unit 5 by a connecting element 22. The connecting element 22 is arranged in the connecting housing 11 between the third and fourth interruption units 4, 5. The connecting housing 11 is arranged with its ends between the interruption unit 4, 5 or its housing 10 and the insulator 9, which mechanically fixes the interruption unit to the steering gear 7 or the gear housing 8. The connecting element 22 is electrically connected to the fourth interruption unit 3 on the side pointing in the direction of the insulator 9 or the steering gear 7.

On the opposite side of the fourth interruption unit 5, the fourth interruption unit 5 has, on the side directed outward, electrical interfaces 12 for, for example, electrical generators, consumers and/or a power grid, which are switched on and/or off by the high-voltage circuit breaker 1. The high-voltage circuit breaker 1 is electrically arranged between the electrical interfaces 12 of the first and

fourth interruption units

2, 5 for switching a current path through the high-voltage circuit breaker 1 between the two electrical interfaces 12.

Fig. 3 shows schematically the arrangement in a plan view or the use of the high-voltage circuit breaker 1 according to the invention of fig. 1 and 2, which is designed for switching three phases. Three, in particular identical, high-voltage circuit breakers 1 according to the invention are arranged next to one another in order to be able to switch, in particular simultaneously and/or offset in time, three poles or phases 19, 20, 21.

The previously described embodiments may be combined with each other and/or with prior art. Thus, for example, two, three or more high-voltage circuit breakers 1 according to the invention can be used. Instead of two intersecting

shafts

23 and 24, more shafts with interruption units can be used. The shafts may have a common point of intersection in a star shape, in particular a steering gear and/or a support arranged at the point of intersection. It is also possible to use an arrangement of shafts with crossing points offset from one another, for example with different steering gears and/or supports, which are in particular connected to one another and/or to one another by means of elements of a kinematic chain. The interruption unit, in particular the shaft on which the interruption unit is arranged, may be in one plane or in different planes, in particular in substantially parallel planes. The plane or planes may be arranged parallel to the substrate or at an angle to the substrate. The arm may have one interruption unit or a plurality of, for example two, series-connected interruption units arranged in succession on the shaft.

The arms of the interruption unit or of the shaft on which the interruption unit is arranged may adjacently have a specific angle or angles different from each other. The spacing between adjacent interrupt elements may be the same or different, particularly according to a regular pattern or irregular. The gear housing 8 can be designed, for example, hexagonally with a flange, or for example, circularly with a flattened area, as viewed from above.
