How to discharge ceramic capacitors in a capacitor cabinet

Recently, the editor saw an interesting question in the ceramic capacitor forum. How do you use the capacitor cabinet?

What makes me curious is that for the first time, the ceramic capacitors have heard of capacitor cabinets. So the editors have explored them and learned about the discharge of ceramic capacitors in the capacitor cabinet. I hope everyone can add relevant knowledge.

How to discharge the ceramic capacitor in the capacitor cabinet? Use resistor discharge, according to the size of the capacitor, the voltage level, the voltage is low, and the resistor with a resistance value greater than 10w is used. The two ends of the resistor are tied to the dry wooden stick to touch the two ends of the capacitor until the capacitor is touched. If there is no spark at the end, then touch it directly with the wire, so that it is completely cleaned, but for high voltage and large capacity (1000v or more and 10UF or more), the resistance of the selected resistor should be more than 5K and the power is greater than 5w. The value of the large resistance discharge time is longer, there is no harm to the capacitor, the discharge of the capacitor with high voltage and large capacity must pay attention to safety. Confirm that the resistor has no spark and then directly touch the two ends of the capacitor with the wire. In terms of the capacitance of the device.

The capacitor cabinet has low voltage and high voltage. The high voltage parallel reactive power compensation device is a capacitive reactive power compensation device for improving power factor, adjusting voltage and reducing power loss in 6KV and 10KV power systems; a low voltage power supply system The amount of reactive power changes as the load changes. If the capacity of the low-voltage capacitor compensation is fixed to the low-voltage capacitor cabinet structure, then the total compensation of the total power of the power system can be satisfactorily compensated.
