The invention relates to a vacuum switch arc comprehensive experimental device. The device comprises a vacuum switch arc generating module, a walking shooting module and temperature-magnetic field control modules. The vacuum switch arc generating module is placed on the ground. The walking shooting module is placed at the periphery of the vacuum switch arc generating module. Four temperature-magnetic field control modules are placed at the periphery of the vacuum switch arc generating module. The vacuum switch arc generating module comprises a vacuum hood, a cone base and a power line and also comprises a static contact, a moving contact, an electromagnetic coil, a connecting rod, a supporting rod, a connecting block, a cross bar, a guide rail and a baffle plate. According to the vacuum switch arc comprehensive experimental device, the automatic contact and separation between the moving contact and the static contact are fully realized, and the operation by experimental personnel is not needed. The influence of human factors in the process of arc generation is reduced, and the personal safety of the experimental personnel is effectively protected.
Description
technical field [0001] The invention belongs to the field of vacuum electric arc, in particular to a comprehensive experimental device for electric arc of vacuum switch. Background technique [0002] With the gradual consumption of fossil energy, the world's energy crisis has become increasingly prominent. In the key link of energy transmission, the research on how to reduce the energy loss in switching devices is of great significance. At present, in the actual operation of HVDC transmission, the most widely used circuit breaker type is filled SF 6 Circuit breakers with gas as the arc extinguishing medium, but due to SF 6 The gas has a great influence on the greenhouse effect and the toxic gas produced by the decomposition during discharge is corrosive to a certain extent. Therefore, in order to establish an environmentally friendly society, SF 6 Circuit breakers will gradually be phased out in the future. Vacuum circuit breaker is a switching device that has been devel...
