Abstract
The invention discloses a kind of circuit breaker grading shield, comprise the cover body that top has through hole, the cover oral area of described cover body has a breach, the part of cover oral area except coupling part of described cover body has the limit to cover inner bending, a described coupling part being provided with connecting through hole of to extend from described bending edge cover mouth is respectively had on the breach both sides of described cover oral area, described cover body has multiple leakage material through hole, the outer surface of described cover body has epoxy resin sulfuric horizon.The present invention compared with prior art, solves the circuit breaker not being suitable for the insulated tension pole of end motion under circuit breaker polar of current circuit breaker grading shield, can not the problem of pole lower end of protective circuit breaker.
Description
Technical field
The present invention relates to high-pressure vacuum breaker manufacturing technology field, especially a kind of circuit breaker grading shield for high-voltage vacuum circuit breaker polar post lower wire end.
Background technology
At present, the structure of the grading shield adopted both at home and abroad is annular mostly, is used for contact of breaker and circular busbar, and for the protection of fixed insulation.But inapplicable for the insulated tension pole of end motion under high-voltage vacuum circuit breaker polar post, can not the pole lower end of protective circuit breaker.
Summary of the invention
Problem to be solved by this invention be to provide a kind of can the circuit breaker grading shield of electric-field intensity distribution of balanced high-voltage vacuum circuit breaker polar post lower end.
In order to solve the problem, technical scheme of the present invention is: this high-pressure vacuum breaker grading shield, comprises the cover body that top has through hole.The cover oral area of described cover body has a breach, the part of cover oral area except coupling part of described cover body has the limit to cover inner bending, a described coupling part being provided with connecting through hole of to extend from described bending edge cover mouth is respectively had on the breach both sides of described cover oral area, described cover body has multiple leakage material through hole, described cover body applies epoxy resin sulfuric horizon.
Owing to have employed such scheme, the present invention compared with prior art has following beneficial effect:
This circuit breaker grading shield serves the effect of balanced circuit breaker lower wire end surrounding voltages; protect insulated tension pole and the epoxy resin insulating layers of circuit breaker; meanwhile, because its outer surface has epoxy resin sulfuric horizon, make the overall withstand voltage properties of circuit breaker better.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of embodiment of the present invention circuit breaker grading shield.
Fig. 2 is embodiment of the present invention circuit breaker grading shield front view.
Fig. 3 is embodiment of the present invention circuit breaker grading shield vertical view.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Circuit breaker grading shield of the present invention shown in Fig. 1, Fig. 2 and Fig. 3, include the cover body 1 that top has through hole, the cover oral area of cover body 1 has a breach, the part of cover oral area except coupling part of cover body 1 has the limit 2 to cover inner bending, a described coupling part being provided with connecting through hole of to extend from bending edge 2 cover mouth is respectively had on the breach both sides of cover oral area, cover body 1 has multiple leakage material through hole 11, the outer surface of cover body 1 has epoxy resin sulfuric horizon.
Connection, the assembly technology of grading shield of the present invention and circuit breaker are as follows: be placed in the mould of epoxy resin insulating layers 8 by the circuit breaker grading shield made, when casting epoxy resin insulating barrier 8, due to cover body 1 side having multiple leakage material through hole 11, liquid epoxy resin can be made to pass through smoothly, when epoxy resin cooling curing, cover body 1 is just fixed on epoxy resin insulating layers 8.Then, extend the coupling part of the bending edge 2 outside cover body 1 and one end of flexible link 4 is fixed on the lower wire end 5 of circuit breaker polar by fixed screw 10, the through hole on cover body 1 top passes by the moved end 6 of vacuum interrupter 7, and fix with the other end of flexible link 4, then be connected with insulated tension pole 9.
By this circuit breaker grading shield, make the Electric Field Distribution of the copper bar lap-joint of high-pressure vacuum breaker lower wire end 5 even, serve the effect of protection insulated tension pole 9 and epoxy resin insulating layers 8, make the overall withstand voltage properties of circuit breaker better.
