1. Strengthen the inspection and inspection of the capacitor cabinet in operation. (Monitoring temperature, voltage and current. The ambient temperature of the capacitor cabinet must not exceed 40 degrees Celsius, and the temperature of the capacitor body must not exceed 60 degrees Celsius; for voltage monitoring, it is generally stipulated that the capacitor can be operated for a long time when the voltage is higher than 1.05 times the rated voltage, and allowed for a day and night. In the middle, the maximum is not more than 1.1 times the rated voltage is not more than 6 hours; when inspecting, check whether the capacitor casing is expanded, the porcelain casing is broken, the oil leaks, the joint is hot, and the ventilation is good.)
Second, the reactive power automatic compensation controller is a key component of the capacitor cabinet. Whether it can work normally directly affects the normal operation of the capacitor cabinet. Therefore, the user must fully understand the functional characteristics of the controller, the use conditions, technical parameters, installation wiring, general qualitative inspection, and system troubleshooting.
