Power capacitor explosion prevention measures

May 08, 2019

Capacitors explode during operation, lightly damage the power distribution equipment, and damage the building and cause fires. Therefore, certain measures should be taken to prevent it.

(1) Under normal circumstances, the effective value of the current passed by each group of phase capacitors is

I=U/Wc

The capacitive reactance of the Wc-capacitor.

According to the current amount, 1.5 to 2 times, equipped with a fast fuse, the protection capacitor will not continue to generate heat and explode when it breaks down.

(2) Install an ammeter on each phase of the compensation cabinet to ensure that the current difference between each phase does not exceed ± 5%.

(3) Strengthen the inspection of the capacitor bank. Especially in the summer high temperature period, the temperature rise of the capacitor should be monitored. If abnormal conditions such as oil leakage and drum belly are found, it should be immediately withdrawn to prevent explosion.

The above is the Power capacitor explosion prevention measures we have listed for you. You can submit the following form to obtain more industry information we provide for you.
