| 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 as-suring reliability and actual result of such reactive power device. In this paper, the switch for reac-tive power compensation device of capacitor is taken as object, its present application status and ex-isting 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 switc-hing and achieves smooth switching. Its feasibility and market value are verified through system simu- lation and application in 10 kV line. |
