Because the vacuum medium has high arc extinction performance, the therefore switch that adopts vacuum interrupter to make, it is little, in light weight to have a volume, and the life-span is long, series of advantages such as environmentally safe.Raising along with China's vacuum interrupter manufacturing technology, what the mechanical endurance of vacuum switch and electric life had reaches about 100,000 times, be applicable to the place of frequent operation, it is very desirable being used for the switching high-voltage capacitor, and the application aspect the reactive power compensation or blank on post at present, the in good time for this reason special-purpose vacuum switch of capacitor group switching of developing is to satisfy the demand in market.
Summary of the invention
The purpose of this utility model is to provide a kind of good arc extinguishing switch of vacuum medium that utilizes, and the power capacitor that needs frequent movement is carried out switching, reduces the special-purpose vacuum switch of capacitor group switching of the volume of reactive power compensator.
The technical solution of the utility model realizes in the following manner: the special-purpose vacuum switch of capacitor group switching, form by Switch main body and intelligent control box two parts, Switch main body comprises multi-stage vacuum arc control device assembly, operating mechanism, power transmission shaft, high voltage potential transformer and casing, and intelligent control box comprises intelligent controller; Switch main body is connected by cable with intelligent control box, it is characterized in that: described multi-stage vacuum arc control device assembly is installed on the casing, tripping spring on the power transmission shaft is respectively by being connected with the corresponding axle of vacuum extinction chamber component, the motor of operating mechanism closes combined floodgate pallet and power transmission shaft, divide by drive system, realizes the automatic switchover of vacuum switch.
Above-mentioned drive system is to be connected with the combined floodgate pallet by chain by switching-in spring.
Be connected with torsion spring on the above-mentioned combined floodgate pallet.
Above-mentioned multi-stage vacuum arc control device assembly is three groups.
Adopt the utility model structure, because the vacuum medium has high arc extinction performance, therefore it is little, in light weight to have volume, and the life-span is long, series of advantages such as environmentally safe, its mechanical endurance and electric life have reached about 100,000 times, can reduce the volume of reactive power compensator significantly, improve the reliability of device, be applicable to the place of frequent operation, expanded the range of application of vacuum switch.
