The structure of the seal pole disclosed by the utility model is more reasonable; and the external epoxy resin insulation shell is formed by carrying out cast forming on imported epoxy resin by an automatic pressure gelling technique, thereby effectively reducing the influence of the external force impact and the external dirty environment on the internal vacuum arc extinguish chamber, so that the seal pole disclosed by the utility model can operate more reliably.
Description
Technical field
The utility model relates to a kind of indoor high-voltage vacuum circuit breaker, is specifically related to a kind of pole of indoor high-voltage vacuum circuit breaker.
Background technology
Circuit breaker is can close to close, carry and cut-off the electric current under the normal loop condition, and can close the switching device that closes, in official hour, carries and cut-off the electric current under the unusual loop condition (comprising short circuit condition).Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application.Primary cut-out is called high-voltage switch gear again, is the main electric control appliance of power plant, electric substation, and primary cut-out is divided into oil circuit breaker, sulfur hexafluoride breaker, vacuum circuit-breaker and compressed-air circuit breaker etc. again by the difference of its arc extinguishing.During work, when system normally moved, primary cut-out can cut off and connect the zero load and the load current of circuit and various electric equipments; When system broke down, it cooperated with relaying protection, and ability is the disengagement failure electric current rapidly, to prevent expansion accident scope.Therefore, the quality of primary cut-out work directly has influence on the safe operation of electric power system.
Yet; The structure of the pole of the indoor high-voltage vacuum circuit breaker of prior art is reasonable not enough; Especially irrational shell mechanism; Make it can not effectively reduce the impact of external force, can not effectively deaden outside filthy environment, had a strong impact on the reliability service of indoor high-voltage vacuum circuit breaker internal structure.
The utility model content
The utility model provides a kind of pole that can effectively prevent external force to the impact of internal structure, the influence of avoiding the external environment condition of filth, the reliable more indoor high-voltage vacuum circuit breaker of operation in order to overcome the deficiency that prior art exists.
The utility model is realized through following technical scheme: a kind of pole of indoor high-voltage vacuum circuit breaker; The epoxy resins insulation shell, vacuum interrupter, upper bracket, last outlet seat, lower carriage and the following outlet seat that comprise cast molding; Said upper bracket, said vacuum interrupter, said lower carriage are set in turn in the said epoxy resins insulation shell from top to bottom; Said upward outlet seat is arranged at the side of said upper bracket; Said outlet seat down is arranged at the side of said lower carriage, and said vacuum interrupter is provided with upper contact head, static conductive rod, following contact and moving conductive rod, and said upper contact head is positioned at the said top of contact down; Said upper contact head is electrically connected with said upper bracket through said static conductive rod, and said contact down is electrically connected with said lower carriage through said moving conductive rod.
Also comprise conductive clip, be flexible coupling and insulated tension pole; The lower end of said moving conductive rod is passed the bottom of said vacuum interrupter and is stretched out downwards; Said moving conductive rod successively through said conductive clip, said be flexible coupling be connected with said insulated tension pole, said be flexible coupling be electrically connected with said lower carriage through a conducting block.
The beneficial effect of the utility model is: the structure of the utility model is more reasonable; Its outside epoxy resins insulation shell adopts automatic pressure gelation process with the cast molding of import epoxy resin; Can effectively reduce of the influence of the filthy environment of external impacts and outside, make the utility model operation more reliable inner vacuum interrupter.
