Definitions

the present invention relates to an automatic circuit breaker which has a whole series of important advantages and important innovations compared to current circuit breakers used for identical or similar purposes.
the invention relates to a circuit breaker mechanism having a breaking capacity by limiting the current.
the automatic circuit breaker object of the present invention is essentially constituted by mechanisms which execute the normal closing and opening of the circuit breaker, opening by thermal tripping, opening by magnetic tripping and opening by short circuit.
the normal operating mechanism for setting and breaking the circuit breaker has the novelty of being formed of only five parts: handle, lever spring, connecting rod, mechanism spring and movable contact.
This engagement is composed of two pieces of metal wire in which the generators are parallel, the section of the two pieces can be arbitrary, cylindrical, square, rectangular, etc.
this column By deforming and changing position, this column exerts pressure on the rod, developing a spring action thereon to maintain it in the pre-set position regardless of the mounting position of the switch.
the spring action is retained when the device establishment maneuver is initiated, then reappearing after the connecting rod has started to rest on the mechanism spring.
the novelty of the electromagnetic opening device is that the fixed contact also performs the functions of a magnetic casing, by closing the magnetic circuit of the magnetic tripping mechanism.
it is dimensioned, by its thickness, and by virtue of the housing provided for the coil, so that the windings of this coil are concentrated in the interval between the carcass and the movable core, which makes it possible to obtain a magnetic tripping mechanism without fixed core, thus bringing significant technical and economic advantages compared to current circuit breakers.
each of the functions mentioned is provided by a different part, and the interlocking is provided by two parts. In the usual construction this function is performed by at least four pieces.
the circuit breaker according to the invention comprises a striker which performs multiple functions which, in the case of current circuit breakers, are carried out by a greater number of parts, which implies a notable advantage, both in price and in simplicity of construction.
the apparatus comprises a housing composed of a carcass 1 and a cover 2 made of insulating material, a set of elements constituting the system for interrupting the electric current, and which are actuated manually at using a lever M which emerges outside the housing, and a short-circuit extinguishing system 3 essentially formed by a chamber 4 for blowing the arc, and an arc track 5.
the electrical current interruption system is a mechanism which is made up of five kinematic chains.
the first chain A is formed of the lever M which rotates around an axis 10, which is part of the carcass 1, of a connecting rod 11, one end of which is threaded into a hole 12 made in the lever M and in which it can rotate freely, the other end being free, and a spring 14 for resetting the lever.
the second kinematic chain B is formed of the movable contact CM, which is a piece of conductive material which rotates around the axis 20, which is part of the carcass 1, and of a mechanism spring 21 having four support points , the first support point 28 (in the closed switch position shown in FIG. 1) being on the free end 13 of the connecting rod 11 and on the movable contact CM, a support point 22 on the contact mobile CM, and another fulcrum 27 on the carcass 1.
the third kinematic chain C is formed by a magnetic trip mechanism which responds electromagnetically to an excess of current in the circuit in which the circuit breaker is inserted.
This chain is formed by a movable core 30 which slides inside a spool pin 31.
the fourth set D is composed of a bimetallic strip 40 which responds thermally to the excess current which passes through the circuit in which the circuit breaker is inserted, thus constituting the thermal trip system.
the last kinematic chain E is formed by the striker 50 made of a piece of insulating material which rotates around the axis 51, which is part of the carcass 1, and of a thermal rod 55.
the striker has four main functional points : the magnetic opening point 52, the point of rotation of the thermal rod 55; the third functional point is the trigger arm 56 and, finally, the external trigger points 57.
the electric current flows through the tongue 61, which is welded to one end 62 of the electromagnetic coil 32. From the coil 32, the current flows to the fixed contact CF through the contact pad 33. From the fixed contact CF, it passes in mobile contact CM through contact point 34. At this contact point, there can be two types of construction: one in which the fixed contact CF comes into direct contact with the mobile contact CM and another in which this contact is made via a contact pad 35.
the current flows to the bimetal 40 through a braid 45 welded to the movable contact CM at one end and to the bimetal 40 at the other end.
the current reaches the output terminal 63 through the bimetal 40 and a second braid 42.
the different mechanisms that make up the circuit breaker correspond to five operating modes: normal closing of the circuit breaker, normal opening of the circuit breaker, opening by thermal tripping, opening by magnetic tripping, and opening by short circuit.
the normal circuit breaker establishment and breaking mechanism is formed by chains A and B.
the contact continues to push the end of the spring 28, pushing it through the end 13 of the connecting rod 11 and acting by the fulcrum 28 of the spring 21 on the movable contact CM; there is a rotation of this movable contact about the axis 20, so that the end 29 of the movable contact CM meets the fixed contact CF, establishing the electrical contact while, when we continue to turn the lever M until the end of its travel, defined by the free end of the connecting rod 13, this causes the spring 21 to bend, creating a contact pressure force at point 34.
Normal opening is carried out by turning the lever M from the setting position (figure 1) to the cut-off position (figure 2).
the normal cut-off mechanism is the same as that of establishment, and it is formed by the kinematic chains A and B.
the spring 21 causes the movable contact CM to rotate about the axis 20 by relaxing the compression established in the body of the spring 25 during closing.
the spring resets the handle 14, by turning the handle M to its cut-off position.
the opening by electromagnetic trip occurs in the presence of an excess of overcurrent in the main current circuit.
the electric current Passing through the coil 32, the electric current generates a magnetic flux inside the circuit formed by the fixed contact CF (which acts as a magnetic carcass) and the movable core 30.
the magnetic flux creates in this core an electromagnetic force which tends to make it advance, sliding inside its guide 31 (coil axis) in the direction of the striker 50.
the rotation of the striker 50 causes the trip arm 56 to move, causing the contacts to open in the same way as in the opening by thermal trip.
the force which pushes the movable core 30 is much greater than in the case of the opening by electromagnetic triggering.
This force is transmitted to the striker 50, by rotating it on the axis 51. Through the trigger arm 56 of the striker 50, this rotation acts on the setting and breaking mechanism A and B of the circuit breaker in the same way than in the case of thermal and magnetic opening.
the striker 50 continues to rotate, so that the extraction point 70 comes into contact with the movable contact CM, transmitting to it a pulse which makes it rotate around the axis 20.
