Abstract
The invention discloses a supporting fixture of a rectangular conductor, which has good insulating performance and high intensity. The M-shaped supporting fixture aims at solving the problems that the volume of the groove type conductor in the present medium/high-voltage electric field is large, the requirement for the volume of a wall bushing is higher and the cost is high. Supporting ribs are arranged at the two sides of the supporting fixture. The supporting fixture is suitable for load-bearing a clamping plate of the rectangular conductor with the working current of 2,000 to 6,300A. One to four rectangular conductors can be installed, four rectangular conductors can be divided into two groups, each group comprises one to two rectangular conductors, two groups of grooves are symmetrically arranged, the conductors are separated by bulges between the grooves, and inclined planes which are arranged at the bottom parts of the grooves can support the conductors to some degree. The supporting fixture is made of nylon materials and is formed by a mould through pouring; the flexibility of the materials is good and the conductors cannot be damaged; the rectangular conductors with different specifications can be installed; the insulating performance is good, the intensity is high, and the practical application range is wide.
Description
Technical field
The present invention is applied to the mesohigh electric field, specifically a kind of supporting fixture of rectangular conductor.
Background technology
Conductor is to be used for electric energy transmitting, and its cross sectional shape, size and quantity etc. have determined all electric energy what it carries, for 15KV and following electric pressure; Operating current reaches the above transmission means of 4000A; When adopting multi-slice rectangle conductor, when it passes through steel structure panel beating parts, must install non-conducting material goods (being commonly referred to wall bushing) additional and insulate; Its effect has two: 1) insulating effect, 2) conductor is supported.When 4000A～6300A operating current adopted rectangular conductor to carry, it is important that the shape of clamping plate through walls and intensity show especially.
In the mesohigh electric field; Existing clamping plate through walls are processed by 3～5 thick insulating material or copper coins at present; The bad easy crushing of intensity of processing with insulating material; Copper coin is processed intensity and well but is prone to hinder conductor, the anchor clamps of equidistant three conductors of domestic existing support, and the ampacity in maximum rectangular conductor cross section is 4000 amperes.When carrying more than 4000 amperes (5000～6300 amperes) operating current, because supporting way preferably not, so all adopt groove shaped conductor, but the groove shaped conductor volume is bigger, and corresponding wall bushing volume requirement is bigger, and cost is higher, does not have manufacturer production at present.As do not adorn wall bushing, and as if certain a bit locates to have an accident mutually in A, B, the C three-phase conductor, the expansion that will cause the accident, even influence whole electric power system, so the conductor support fixture has the obstruct accident to expand the effect of prolonging.
Summary of the invention
The purpose of this invention is to provide a kind of good insulation preformance, high-intensity supporting fixture of rectangular conductor, bigger to solve in the present mesohigh electric field groove shaped conductor volume, the wall bushing volume requirement is bigger, the cost problem of higher.
The shape of anchor clamps of the present invention is M shape, and there is brace rod both sides.
Innovative point of the present invention:
1) it is practical, can assemble 1～4 rectangular conductor.
2) anchor clamps adopt nonmetallic materials compression moulding, have good toughness, do not hinder conductor, have certain intensity again, and conductor is played a supportive role.
3) with the thickening of conductor contact-making surface, and adopt an oblique angle, can adjust for the error of different manufacturers cross-sectional area of conductor manufacturing.
4) these anchor clamps are equipped with certain thickness brace rod along the limit, and middle inner chamber is except that guaranteeing brace rod thickness, and irregular die cavity place is lower than the thickness at edge, form the irregular casement chamber of two symmetries.
5) center is provided with the fixed length circular hole, can its conductor by different cross section be fixed on the insulating material product.
6) respectively there is the groove of two certain width sizes the fixing hole both sides, in the middle of two grooves convexity are arranged, and conductor is separated.
The present invention is mainly used in the bearing great current rectangular conductor, and through the switchgear metal shell time, the hollow parts that must have insulating material to process guarantee the insulation distance of conductor, normally move in the time of just can making conductor charged.When multi-slice rectangle conductor passes hollow parts, support fixture of the present invention is installed, multi-slice rectangle conductor is supported subsidiary can playing to multi-slice rectangle conductor arrangement clamping action.
These anchor clamps can be divided into two groups of supports with conductor, two every group, leave between every group greater than the conductor width spacing.
The present invention is used for the supportive conductors in the wall bushing, its good insulation preformance, intensity height.
The present invention is applicable to the clamping plate of the operating current rectangular conductor that carries 2000A～6300A; One to four rectangular conductor can be installed, and four are divided into two groups, one to two every group; Two groups of groove symmetric arrangement; Convexity between groove is separated conductor, and bottom portion of groove is provided with the inclined-plane, and conductor is had certain support.The present invention adopts a kind of nylon material to use the die casting moulding, and the material pliability is good, does not hinder conductor, can adorn the rectangular conductor of different size, its good insulation preformance, intensity height, and usage range is wide.

Embodiment
Following execution mode can make those skilled in the art more fully understand the present invention, but does not limit the present invention in any way.
The shape of anchor clamps 1 of the present invention is M shape, and there is brace rod both sides.
Be provided with protruding 3 in the anchor clamps 1 and form groove 5, the width of groove 5 is 8-14mm, and greater than the width of conductor 6, the convexity 3 between groove is separated conductor 6, and bottom portion of groove is provided with inclined-plane 51, and conductor is had certain support.
In Fig. 3, Fig. 4 and second kind of execution mode of the present invention shown in Figure 6, the area of irregular die cavity 22 is big.
The present invention is applicable to the clamping plate of the operating current rectangular conductor that carries 2000A～6300A, and one to four rectangular conductor can be installed.
Through the switchgear metal shell time, must there be insulating material to process.The hollow parts of the present invention guarantee the insulation distance of conductor, normally move in the time of just can making conductor charged, when multi-slice rectangle conductor passes hollow parts, multi-slice rectangle conductor are supported, subsidiary can playing multi-slice rectangle conductor arrangement clamping action.The present invention adopts a kind of nylon material to use the die casting moulding, and the material pliability is good, does not hinder conductor, can adorn the rectangular conductor of different size, and usage range is wide.
Two groups were supported conductor about anchor clamps of the present invention were divided into; Can not change fixing hole on the insulating material product; By user mode shown in Figure 5; The anchor clamps that will have identical irregular type cavity area make up, and also can will have the anchor clamps combination of different irregular type cavity areas by Fig. 6, accomplish the support to the conductor in different size cross section.Along with the difference of cross-sectional area of conductor, also can change fixing hole on the insulating material product, anchor clamps are moved up and down.
