■Introduction:
This kind of capacitor has the function of self-healing, which means it can continue for run because of its ability to resume the insulation after breakdown during operating. Mainly used to protect the semiconductor by absorbing and cutting down the overvoltage occurred during the switching process. The epoxy resin filled capacitor have good safety and reliability, with smaller size, less weight, which makes it easy to install.
This capacitor is widely applied in the overvoltage protection and AC phase change absorbtion of the thyristor and silicon controlled rectifier, and in the damping absorbtion of high voltage DC transmission converter.
