Description
Technical field
The utility model relates to a kind of breaker assembly, especially a kind of insulating polar pole.
Background technology
Circuit breaker (English name: circuit-breaker; circuit breaker) refer to the electric current that can close, carry and cut-off under normal loop condition, and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition (comprising short circuit condition) in official hour.
Circuit breaker can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current.At present, obtain a wide range of applications.
Circuit breaker such as vacuum circuit-breaker generally has pole, and the pole column structure of prior art, when ensureing electric property, can not reduce costs, and therefore under the prerequisite keeping electric property, has reduced costs into an insoluble problem
Utility model content
The purpose of this utility model is, provide a kind of ensure electric property prerequisite under reduce costs, compact insulating polar pole rational in infrastructure.
The utility model solves the technical scheme that its technical problem adopts: a kind of insulating polar pole, comprise insulating cylinder, vacuum interrupter, conductive pole, upper conduction outlet, lower conduction outlet, upper conduction outlet, lower conduction outlet are separately positioned on the two ends up and down of insulating cylinder, upper conduction outlet, lower conduction outlet are wholely set with insulating cylinder respectively, also comprise end cap, be provided with an opening at the top of insulating cylinder, end cap is embedded on opening, forms concealed structure.
Of the present utility modelly to be set to further: conductive pole arranges in insulating cylinder, and one end is connected with upper conduction outlet, the other end connects vacuum interrupter, and lower conduction outlet is arranged on below vacuum interrupter, vacuum interrupter and insulating cylinder inwall screw rigid attachment.
Of the present utility modelly to be set to further: also comprise insulated tension pole assembly, insulated tension pole assembly is arranged on below vacuum interrupter.
Of the present utility modelly to be set to further: also comprise strutting piece, upper conductor end socket, lower wire end socket, insulating cylinder is provided with upper and lower two sealings, upper conductor end socket, lower wire end socket seal upper and lower two sealings respectively, strutting piece is arranged on inside lower sealing, vacuum interrupter is arranged on strutting piece, and strutting piece and bottom head are bolted to connection.
Concealed fastening design in said structure pole top end cover adopts; Upper and lower conduction outlet and insulating cylinder adopt integrated design, and structure cylinder is clean and intensity is high; Conductive contact surfaces is few, and inside comprises dynamic/static contact only 5 contact-making surfaces, greatly reduces the resistance value of electric conductor; Fixing enhancing nylon and the insulating cylinder inwall screw rigid attachment of adopting in vacuum interrupter lower end designs, and mechanical strength reliability is high; The utility model pole versatility is good, and its profile is consistent with outside installed part and pole, therefore the accessory general character is very good, and circuit breaker spaced apart scope is joined extensively by institute, all general between 150mm ~ 275mm.
