Existing parts structure under the conduction connecting structure utilization of the technical program between switch contact and lower wire end daughter board, make the attaching parts multifunction application between lower switch contact and insulated tension pole, be designed to two-way composite conducting in parallel, met stable, reliable and trouble free service in the technical requirement of large rated current that reaches 1250A.
Description
Technical field
Patent application of the present invention relates to outdoor high-voltage pole vacuum circuit breaker or automatic circuit.
Background technology
The agent structure of outdoor high-voltage vacuum breaker or automatic circuit comprises operation panel and is arranged at the hermetically sealed pole of three-phase on operation panel top, pole internal upper part encapsulated vacuum arc-chutes, the lower switch contact of vacuum interrupter connects with operation panel transmission mechanism driving shaft connecting lever through the insulated tension pole through pole lower space, and on vacuum interrupter, stationary contact connects the upper connecting terminal plate of pole. Lower switch contact is flexible coupling and lower wire end daughter board conductive attachment through conduction, and its galvanic circle is upper connecting terminal plate through the conductive contact of vacuum interrupter, is flexible coupling, connects lower wire end daughter board. Existing circuit breaker structure exists and meets the highest low technical problem of load current value, the highlyest can only reach 630A rated current technical indicator, its reason is to be flexible coupling and to be born large operating current by the larger conduction of internal resistance, the heat of its generation can cause temperature rise speed and temperature rise value in pole to surmount upper limit technical requirement, cannot make it in 12KV, larger 1250A rated current working environment, normally work.
Summary of the invention
The goal of the invention of patent application of the present invention be to improve the specified current work grade of product technical indicator, both make frequent operation occasion also can be reliably and with long-term, outdoor high-voltage pole vacuum circuit breaker or the automatic circuit of steady operation. the outdoor high-voltage pole vacuum circuit breaker that patent application of the present invention provides or automatic circuit technical scheme, its main technical content is: a kind of outdoor high-voltage pole vacuum circuit breaker or automatic circuit, comprise operation panel and the three-phase solid-sealed pole that is arranged at operation panel top, pole internal upper part encapsulated vacuum arc-chutes, the lower switch contact of vacuum interrupter connects with operation panel transmission mechanism through the insulated tension pole through pole lower space, on vacuum interrupter, stationary contact connects the upper connecting terminal plate of pole, lower switch contact is through being flexible coupling and lower wire end daughter board conductive attachment, lower wire end daughter board connects with the conduction ring seat in pole, conducting rod between lower switch contact and insulated tension pole is through conduction ring seat centre bore, be connected through conduction watch chain conduction with conduction ring seat centre bore.
In above-mentioned overall technical architecture, be also provided with heat abstractor (to not having in my sketch, so cannot further set forth its structure). This heat abstractor refers to sheet for being fixed on the some heat radiations of lower switch contact conduction fixture block, and heat radiation refers to that sheet can be flexible coupling conduction timely and conduct electricity fixture block work calories and distribute, and has avoided heat accumulation, has effectively controlled temperature rise.
The outdoor high-voltage pole vacuum circuit breaker of Patent Application Publication of the present invention or automatic circuit technical scheme, on conducting electricity on original Jin You mono-tunnel the conductive structure basis being flexible coupling, increase another road conduction connecting structure, existing parts structure under this conduction connecting structure utilization between switch contact and lower wire end daughter board, make the attaching parts multifunction application between lower switch contact and insulated tension pole, conduct electricity and transmission integrated design, realize two-way composite conducting in parallel, reach effective shunting, weaken the technical purpose of temperature rise in pole, meet stable, reliable and trouble free service is in the technical requirement of large rated current that reaches 1250A. in conjunction with adopting heat abstractor, its temperature rise in 24 hours is only 35 DEG C of left and right, far exceedes the technical standard requirement that country is not more than 65 DEG C again.
