Safety capacitor burst causes(I)

The cause of safety capacitor burst:

1) Due to poor manufacturing quality, internal components of the safety capacitor break down.

2) Insulation resistance is reduced due to poor seal of the casing, and insulation resistance is reduced; due to seepage, oil leakage, and oil surface drop, discharge of the casing or breakdown of the components is caused.

3) Internal free and bulging. When the internal capacitance of the safety capacitor generates corona, breakdown discharge and serious dissociation, the safety capacitor will produce a series of physical, chemical and electrical effects under the action of overvoltage, accelerate the insulation aging, decompose and produce gas, and form a vicious cycle. As a result, the pressure of the tank shell increases, causing the tank wall to blow in and cause burst.
