Description
Technical field
The utility model relates to a kind of pole indoor, outdoor vacuum circuit breaker high pressure galvanic circle that is used for, and particularly has good airproof performance, the good a kind of vacuum circuit breaker polar of insulating properties.
Background technology
Vacuum circuit-breaker generally is used for the electric pressure of 12kV-40.5kV, as the usefulness of the control and the protection of circuit.Vacuum circuit-breaker various vacuum circuit-breakers occurred till now from producing, conclusion is got up, more typically have three kinds: a kind of is to be the vacuum circuit-breaker of insulation with the air, it is the 3AH of representative circuit breaker such as Siemens Company, this circuit breaker alternate and relatively all adopt air insulation, the high pressure galvanic circle part of vacuum circuit-breaker (or claiming the pole part) is generally by upper terminal, vacuum interrupter, lower terminal, insulated tension pole, compositions such as supporting insulator, the vacuum extinction chamber surface generally is exactly pottery or glass, because will tolerate the voltage between fracture, the pottery of this vacuum interrupter or glass shell are generally longer, the overall dimensions of circuit breaker are generally all very big.Another is the vacuum circuit-breaker of compound inslation, it represents circuit breaker is the VD4 of ABB AB, this circuit breaker alternate and relatively adopt air and the compound inslation of epoxy resin, SMC, DMC, its high pressure galvanic circle part (or claiming the pole part) is generally by upper terminal, vacuum interrupter, lower terminal, insulating sleeve or insulation booth, compositions such as insulated tension pole.This circuit breaker is a kind of littler than preceding on the overall dimension owing to adopt the compound inslation of air and epoxy resin, SMC, DMC, the inside of compound inslation if filth be difficult to safeguard and clean.The vacuum circuit-breaker that also has a kind of employing solid insulation that occurred in recent years, it represents circuit breaker is the VM1 of ABB AB, this circuit breaker adopts a kind of megohmite insulant of solid between vacuum interrupter and epoxy package, increase the dielectric strength between the vacuum interrupter off port, the high pressure galvanic circle part of this circuit breaker (or claim pole part) is generally by terminal, vacuum interrupter, lower terminal, the insulation casting matrix, compositions such as insulated tension pole.Owing to adopt a kind of megohmite insulant of solid between vacuum interrupter and the epoxy package, not only increased the external insulation of vacuum interrupter, simultaneously because solid insulation makes the vacuum extinction chamber surface not be subjected to such environmental effects.More than the insulated tension pole of three kinds of circuit breakers all be outer being exposed in the air, all be subjected to Effect of Environmental easily.
The utility model content
For addressing the above problem, the utility model is intended to propose a kind of vacuum circuit breaker polar.
The technical scheme that the utility model addresses the above problem employing is: a kind of vacuum circuit breaker polar, comprise the column casing shape insulation crust that usefulness insulating material casting forms, the vacuum interrupter in the insulation crust is made of porcelain shell, static conductive rod, upper static contact, lower moving contact, moving guide rod, bellows, the radome of cylindricality; On the corresponding insulation crust sidewall of vacuum interrupter upper terminal and lower terminal are installed, upper terminal is connected with the static conductive rod on vacuum interrupter top, and lower terminal is connected with moving guide rod through electric connector, and the moving contact that insulated tension pole drives vacuum interrupter moves up and down; It is characterized in that: sheathed one can move up and down and the flexible insulation sealing gasket of strain with insulated tension pole between insulation crust bottom and insulated tension pole bottom.
Insulated enclosure pad of the present utility model is the rubber sleeve with corrugated expansion joint, and the bottom of rubber sleeve outer and insulation crust is connected and fixed, and the edge engages with the annular groove of the bottom of insulated tension pole in the rubber sleeve; When the lower moving contact that drives vacuum interrupter when insulated tension pole moved up and down, the rubber sleeve outer can move up and down with insulated tension pole, and rubber sleeve is sealed in insulated tension pole in the insulation crust and is hedged off from the outer world, and avoids it to be subjected to the influence of external environment factor.
The beneficial effects of the utility model are: by a sheathed insulated enclosure pad between insulation crust bottom and insulated tension pole bottom, insulated enclosure pad deformation and do not damage sealing gasket thereupon when the insulated tension pole in the insulation crust moves up and down, and make insulation crust inner with the external environment seal isolation, avoid insulated tension pole to expose and in air, be subjected to Effect of Environmental, the insulation crust inner air and outer air does not circulate, and the air of sealing plays increases the electric insulation effect.
