Preventive measures for Fault of Capacitor (II)

Correct selection of switching switch HW emergency stop switch

     When the shunt capacitor is disconnected, because of the arc action between the static and dynamic contacts of the switch ZD-09 CJ10-150A (Foshan type), it will cause the operation overvoltage. In addition to the requirement that the switching capacity of the switch is about 35% larger than that of the shunt capacitor bank, it must also be the HMI0 of the circuit breaker with high insulation recovery strength between contacts, low arc reburning and good arc extinguishing performance.
