The exposed conductive parts of the high-voltage capacitor bank should have a mesh barrier. When conducting external inspections, it is forbidden to open the barrier of the capacitor bank during operation
1、 The exposed conductive parts of the high-voltage capacitor bank should have a mesh barrier. When conducting external inspections, it is forbidden to open the barrier of the capacitor bank during operation.
2、 Any capacitor bank with rated voltage is prohibited from closing with charge. After each disconnection, it must be closed again after a short circuit of three minutes (i.e. a short period of time after discharge).
3、 Replace the fuse of the capacitor when there is no voltage on the capacitor. Before proceeding, the capacitor should be discharged.
4、 The maintenance work of the capacitor bank should be carried out when there is a complete power outage. The power supply should be disconnected first, and the capacitors should be discharged and grounded before work can begin. High voltage capacitors should be operated according to the work order, while low voltage capacitors can be operated according to verbal or telephone commands. But written records should be kept.
