Description
Technical field
This utility model relates to a kind of vacuum circuit breaker.
Background technology
Vacuum circuit breaker because of after its arc-extinguishing medium and arc extinguishing the dielectric of contact gap be all fine vacuum and gain the name；It has that volume is little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, applies the most universal in power distribution network.Vacuum circuit breaker is 3～10kV; indoor distribution in 50Hz three-phase alternating current system; it is available in industrial and mining establishment, power plant, transformer station being used as protection and the control of electric equipment; being particularly well-suited to requirement non-oil ultra high vacuum system, few maintenance and the field of employment of frequent operation, chopper is configurable in middle-placed switch cabinet, double-layer cabinet, fixing cabinet and uses as control and protection high voltage electric equipment.The faster the better for the opening velocity of chopper generally speaking speed, so can make to first open electric current level off to before 0 2～3ms time can cut-off fault current；Otherwise first opening and can not cut-off and extend to next phase mutually, originally first open and open phase after becoming mutually, the arc time increases, and adds the difficulty cut-off, even makes failure of interruption.But opening velocity is too fast, the bounce-back of separating brake is also big, rebounds and the biggest shook play and the most easily produce and restrike, so speed is also considered as this respect factor between Fen.The speed of opening velocity, the energy storage size of moving contact spring and tripping spring when depending primarily on combined floodgate.In order to improve opening velocity, the energy content of tripping spring can be increased, it is also possible to increase the decrement of switching-in spring, this output work and mechanical strength of complete machine of being all necessarily required to improve operating mechanism, reduce technical-economic index.
Current existing vacuum circuit breaker constructions is simple, and action stability is poor, and insulation effect is general, and shield effectiveness is general.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, and insulation effect is good, has good insulation shielding effect, safe and reliable vacuum circuit breaker.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of vacuum circuit breaker, including upper outlet rod, lower outlet rod, end cap and shell, described end cap is located on shell, described end cap is connected with outer casing screw, described upper outlet rod is located in end cap, described lower outlet rod sets in the enclosure, it is provided with sealing ring on described end cap, carbon fiber cover it is provided with in described end cap, it is provided with corrugated tube on described carbon fiber cover, it is provided with aluminum_alloy cover below described carbon fiber cover, described upper outlet rod and lower outlet rod junction are provided with contact, it is provided with cover plate below described shell, described cover plate is fixing with shell to be connected.
As preferably, described corrugated tube is fixing with carbon fiber cover to be connected, and keeps Stability Analysis of Structures reliable.
As preferably, described upper outlet rod is slidably connected with carbon fiber cover, outlet rod conveniently moving in holding.
As preferably, described upper outlet rod is connected with outer casing screw, keeps having stable behavior reliable.
As preferably, described shell is ceramic package, keeps insulation effect good.
The beneficial effects of the utility model are: the end cap of setting and cover plate keep chopper good airproof performance, and safe and reliable, carbon fiber cover and aluminum_alloy cover have good effectiveness, lightweight, conveniently installing, shell has good insulation effect, and contact remains open and closes conveniently.
