Technical field
The utility model relates to a kind of bellows pair to be prevented turning round vacuum interrupter, relates in particular to the two anti-vacuum interrupters of turning round of bellows in a kind of electric power project engineering field.
Background technology
Vacuum interrupter is the core component of mesohigh power switch, make after mesohigh circuitry cuts power supply blow-out rapidly and suppress electric current by managing insulating properties that interior vacuum is good, avoid accident and unexpected generation, the power transmission and distribution control system that is mainly used in electric power, is also applied to the distribution systems such as metallurgy, mine, oil, chemical industry, railway, broadcast, communication, industrial high-frequency heating. and bellows has the distance of repeatedly moving and pull open out and has bubble-tight thin-walled parts.Bellows in traditional vacuum arc extinguish chamber structure does not arrange anti-twisting equipment, and the wall thickness due to bellows in the assembling of complete machine is very thin, and each parts twist in assembling process, easily cause bellows to sprain, and causes product gas leakage.
Utility model content
The utility model is intended to invent the two anti-vacuum interrupters of turning round of a kind of bellows that prevents that in assembling process, bellows is sprained.
A kind of bellows is two prevents that turning round vacuum interrupter comprises moving conductive rod, fairlead, retainer ring, moving cover plate, bellows, connecting ring, keyway, skewed slot and for fixedly mounting the groove of fixture, bellows-sheathed is connected to moving conductive rod middle part, moving conductive rod upper outside is provided with the groove for fixedly mounting fixture, fairlead bottom is provided with protruding key, moving conductive rod middle part is provided with the keyway for coordinating with fairlead epirelief key, fairlead bottom is plugged between moving conductive rod and bellows, moving cover plate is fixed between bellows and guide pipe, fairlead is provided with skewed slot, moving cover plate be provided with fairlead on the retainer ring of skewed slot clamping, guide plate is connected on moving cover plate, bellows lower outside is socketed with connecting ring.
Preferably, described fairlead is provided with at least three skewed slots.
Preferably, described moving conductive rod middle part is provided with at least two keyways, and fairlead is provided with at least two protruding keys that coordinate with keyway.
Preferably, described moving conductive rod middle part is provided with at least two for fixedly mounting the groove of fixture.
The beneficial effects of the utility model are:
1. moving conductive rod upper outside is provided with the groove for fixedly mounting fixture, and in arc control device assembling process, fixture is fixed in the groove on moving conductive rod, prevents that in assembling process, bellows is sprained;
2. fairlead is provided with skewed slot, moving cover plate be provided with fairlead on the retainer ring of skewed slot clamping, prevent that in assembling process, fairlead twists with respect to moving cover plate, thereby prevent that bellows from spraining;
3. fairlead bottom is provided with protruding key, and moving conductive rod middle part is provided with the keyway for coordinating with fairlead epirelief key, prevents that in assembling process, fairlead twists with respect to moving conductive rod, thereby prevents that bellows from spraining.
