Simulation and Experimental Research on Transient Recovery Voltage Distribution Property for Vacuum Switch With Double-break
摘要
Abstract
The explanation of dielectric recovery characteristics and transient recovery voltage distribution properties of vacuum switch with double-break is theoretical basis for its successful interruption. The simulation platform of vacuum switch with double-break was built up by alternative transients program, and the transient vacuum arc model was realized using transient analysis of control systems. The fault current interruption simulations were conducted under the conditions of two interrupters parallel with and without grading capacitors. The experimental model of vacuum switch with double-break was set up, and the transient recovery voltage distribution properties of experimental model were studied. The experimental results and simulation data showed that the successful interruption of vacuum switch with double-break mostly depends on the voltage average distribution between two interrupters in the dielectric recovery process. The voltage distribution between two interrupters is decided by their arc resistances in the dynamic dielectric recovery process, and it is decided by their equivalent capacitors after the dynamic dielectric recovery process. Therefore, the application of low dispersion operation mechanism and the selection of grading capacitors are the key factors of successful interruption of vacuum switch with double-break and multi-break.关键词
