Abstract

In this paper

the colony fault of fuse of capacitor bank and serious damage of capacitor are analyzed in detail based on the structure and operation condition of 35 kV shunt reactive power compensation capacitor bank and through diagnostic tests and theoretical inference

finding that fuse ability decreased of external fuse causes the capacitor bank to generate fault inrush current and fault overvoltage;the faulty inrush current causes colony fusing failure;the faulty overvoltage causes serious damage of capacitor.The prevention measures are specifically raised to prevent reoccurrence of such similar failure.
