This scheme provides a high -voltage vacuum circuit breaker, the difficult heat absorption of high temperature, and effectual high -voltage vacuum circuit breaker simultaneously cools down.
Description
Technical field
The utility model relates to a kind of high-pressure vacuum breaker, belongs to electrical equipment.
Background technology
Vacuum circuit-breaker is a kind of electric elements be often applied in high-tension switch cabinet.High-pressure vacuum breaker not only can cut off or no-load current in closed high circuit and load current; and when system jam by the effect of relay protection; cut off overload electric current and short circuit current, it has quite perfect arc extinguishing structure and enough cutout abilities.The loop resistance of high-pressure vacuum breaker is the main heating source that impact heats up, and the loop resistance of arc control device will account for more than 50% of high-pressure vacuum breaker loop resistance usually.
Application number is that the utility model patent of 201120277603.8 is by the surperficial dual solid insulation technology adopting the isolation of sulfuration insulating barrier, epoxy resin conduit of upper and lower conducting rod, adopt plug-in type silicone rubber sleeve and silica gel to be sealed by docking port when being connected with solid sealed pole of vacuum arc-extinguishing chamber, ensure that upper and lower conducting rod under minimum phase spacing over the ground and phase insulation level.But contact gap contact resistance is the chief component of vacuum interrupter loop resistance, because contact system is sealed in vacuum extinction indoor, and the heat produced externally can only be dispelled the heat by dynamic and static conducting rod.The quiet end cap of vacuum interrupter is directly connected with quiet support, although moved end lid is then covered to move upward and is conducive to moved end by conductive clip, the moved end that to be connected with dynamic support of being flexible coupling and dispels the heat, but because moved end lid connecting link is more, thermally conductive pathways is longer, so the overlapping part that the peak that high-pressure vacuum breaker heats up focuses mostly in moving conductive rod and conductive clip.In actual applications, effectively utilizing quiet end cap to be conducive to the element dispelled the heat, force many deriving from quiet end cap of contact gap heat, the heat of shunting moved end lid, is solve high-pressure vacuum breaker to heat up higher effective measures.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high-pressure vacuum breaker, and high temperature not easily absorbs heat, simultaneously the high-pressure vacuum breaker of good cooling effect.
For achieving the above object, the utility model provides following technical scheme: a kind of high-pressure vacuum breaker, comprise circuit breaker frame, operating mechanism is provided with in frame, handcart-type chassis vehicle is provided with bottom frame, the frame back side is provided with solid sealed pole of vacuum arc-extinguishing chamber, and described solid sealed pole of vacuum arc-extinguishing chamber is made up of dielectric ceramic, and solid sealed pole of vacuum arc-extinguishing chamber surface scribbles reflective heat-insulation paint layer.
