High voltage capacitor main technical performance
Mar 08, 2019

The capacitor is connected with the vacuum switch in parallel. When the vacuum switch is connected with the inductive load, it can not only limit the operating overvoltage to a certain range, but also delay the rise time of the cut-off overvoltage and the reburning overvoltage wave head and reduce the steepness, so as to protect the insulation of the electrical equipment from the shock of the steep wave front. It is used in power systems of 50Hz, 3kV, 6kV, 10kV and 35kV to reduce voltage amplitude by absorbing energy of capacitance and attenuate oscillation by damping effect of resistance so as to prevent overvoltage. At the same time, it is not restricted by the neutral grounding mode, so it is guaranteed to be insulated from the motor. Horizontal coordination, improve the quality of power supply network. In other cases, it can also be used as a high-voltage capacitor, which can reduce atmospheric overvoltage, wavefront steepness and peak value when connected to the ground. With the use of arrester can protect electrical equipment; Matching capacitor for RC overvoltage absorption device of vacuum breaker system.
