Abstract
The invention discloses a grading shield for a circuit breaker. The grading shield comprises a shield body at the top of which a through hole is formed, wherein a notch is formed at the opening of the shield body; the opening part of the shield body is provided with an edge folded towards the inside of the shield except connection parts; the connection parts which are provided with connection through holes and extend out of the opening from the folded edge are arranged on the two sides of the notch of the opening part respectively; the shield body is provided with a plurality of leakage through holes; and the external surface of the shield body is coated with an epoxy resin sulfide layer. Compared with the prior art, the grading shield for the circuit breaker solves the problems that the conventional grading shield for the circuit breaker is not suitable for the circuit breaker of an insulating pull rod moving at the lower end of the polar column of the circuit breaker and cannot protect the lower end of the polar column of the 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 the high-voltage vacuum circuit breaker polar post lower wire end.
Background technology
At present, the structure of the grading shield that adopts both at home and abroad is annular mostly, and is multiplex in contact of breaker and circular busbar, and for the protection of fixed insulation.But the insulated tension pole for end motion under the high-voltage vacuum circuit breaker polar post is inapplicable, pole lower end that can not protective circuit breaker.
Summary of the invention
Problem to be solved by this invention provides a kind of circuit breaker grading shield of electric-field intensity distribution that can balanced high-voltage vacuum circuit breaker polar post lower end.
In order to address the above problem, technical scheme of the present invention is: this high-pressure vacuum breaker grading shield comprises that the top has the cover body of through hole.The cover oral area of described cover body has a breach, the part of cover oral area except the coupling part of described cover body has to the limit of cover inner bending, a described coupling part that is provided with connecting through hole of extending from described bending edge outside the cover mouthful is respectively arranged on the breach both sides of described cover oral area, have a plurality of leakage material through hole on the described cover body, applying epoxy resin on the described cover body has sulfuric horizon.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
This circuit breaker grading shield has played the effect of voltage on every side of balanced circuit breaker lower wire end; insulated tension pole and the epoxy resins insulation layer of circuit breaker have been protected; simultaneously, because its outer surface is coated with the epoxy resin sulfuric horizon, make the whole withstand voltage properties of circuit breaker better.
Description of drawings
Fig. 1 is the assembling schematic diagram of embodiment of the invention circuit breaker grading shield.
Fig. 2 is embodiment of the invention circuit breaker grading shield front view.
Fig. 3 is embodiment of the invention circuit breaker grading shield vertical view.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1, Fig. 2 and circuit breaker grading shield of the present invention shown in Figure 3, include the cover body 1 that the top has through hole, the cover oral area of cover body 1 has a breach, the part of cover oral area except the coupling part of cover body 1 has to the limit 2 of cover inner bending, a described coupling part that is provided with connecting through hole of extending from bending edge 2 outside the cover mouthful is respectively arranged on the breach both sides of cover oral area, have a plurality of leakage material through hole 11 on the cover body 1, the outer surface of cover body 1 is coated with the epoxy resin sulfuric horizon.
Being connected of grading shield of the present invention and circuit breaker, assembly technology are as follows: the circuit breaker grading shield that makes is placed in the mould of epoxy resins insulation layer 8, when casting epoxy resin insulating barrier 8, owing to have a plurality of leakage material through hole 11 on cover body 1 side, liquid epoxy resin is passed through smoothly, when the epoxy resin cooling curing, cover body 1 just is fixed on the epoxy resins insulation layer 8.Then, extending the coupling part of the bending edge 2 outside the cover body 1 and an 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, be connected with insulated tension pole 9 again.
By this circuit breaker grading shield, make the Electric Field Distribution of copper bar lap-joint of high-pressure vacuum breaker lower wire end 5 even, played the effect of protection insulated tension pole 9 and epoxy resins insulation layer 8, make the whole withstand voltage properties of circuit breaker better.
Claims (1)
1. circuit breaker grading shield, comprise that the top has the cover body of through hole, it is characterized in that: the cover oral area of described cover body has a breach, the part of cover oral area except the coupling part of described cover body has to the limit of cover inner bending, a described coupling part that is provided with connecting through hole of extending from described bending edge outside the cover mouthful is respectively arranged on the breach both sides of described cover oral area, have a plurality of leakage material through hole on the described cover body, the outer surface of described cover body is coated with the epoxy resin sulfuric horizon.
