The principle of the composition of the CBB capacitor is actually relatively simple, that is, two parallel dotted plates, the middle insulating medium composes a core, and two plates each have one lead-out, ie, two electrodes. The CBB capacitor is a polypropylene capacitor. Its main feature is simil

Due to its widespread use, we need to understand some common CBB capacitance detection methods: First, detect small capacitors below 10pF. The capacity of the fixed capacitor below 10pF is too small, use the multimeter to measure, can only qualitatively inspect whether there is leakage, internal sho

Method 1: carefully control the starting voltage and the operating voltage of the shunt capacitor, and make sure that it is within the permitted area. That is, the long-term operating voltage of the CBB capacitor can not exceed 10% of its nominal voltage value. If the operation starts too high, the

The safety capacitor is also polypropylene material, and CBB is also polypropylene. Some engineers say the CBB capacitor will blow up. And JEC editor thinks that it is not a problem caused by pressure failure. The nominal voltage of the safety capacitor is 275V and 310V, and the DC withstand voltage
