Abstract

Shunt capacitor

as one of the main reactive power compensation mode

is used widely in high voltage lines of various power network. The switching device of capacitor is the key part in assuring reliability and actual result of such reactive power device. In this paper

the switch for reactive power compensation device of capacitor is taken as object

its present application status and existing problems are introduced and

a kind of intelligent switching device is specifically designed based on theory analysis

which suppresses effectively transient impulse generated at instant of switching and achieves smooth switching. Its feasibility and market value are verified through system simulation and application in 10 kV line.
