Specification for maintenance and use of Safety Capacitor

Views:0     Author:Site Editor     Publish Time: 2018-04-26      Origin:Site

Safety gauge capacitors should be on duty and should keep a good record of the operation of the equipment.

Inspection of the appearance of the running safety gauge capacitor banks shall be carried out daily in accordance with the regulations. If the expansion of the case is found, it should be stopped in order to avoid malfunction.

Check the safety gauge capacitor bank each phase load can be done by amperometric meter.

(4) the ambient temperature shall not be lower than -40 ℃ when the safety gauge capacitor bank is put into operation, the operating temperature shall be 1 h, the average temperature shall not exceed + 40 ℃ for 2 h and + 30 ℃ for 2 h, and the annual average temperature shall not exceed + 20 ℃. If over, use manual cooling (installation fan) or disconnect the safety gauge capacitor bank from the grid.

Temperature checks at installation sites and the hottest temperature checks on the gauge capacitor housing can be carried out by mercury thermometers, etc., and temperature records (especially in summer) are made.

The working voltage and current of a gauge capacitor shall not exceed 1.1 times the rated voltage and 1.3 times the rated current when used.

When connected with the safety gauge capacitor, it will cause the rise of the grid voltage, especially when the load is lighter. In this case, some or all of the safety gauge capacitors should be cut off from the power network.
