摘要
Abstract
High-voltage motor widely used in power plant, chemical, coal and metallurgy industries, etc many enterprise, the using of circuit-breaker and contactor to switch motor to be a universal conditions. The higher overvoltages would occur during the swiching process, which may destroy the insulation of switch equipment and motor. For proving the ability of a circuit-breaker and contactor to switch high-voltage motors, the laboratory of XIHARI established the substitute circuit according to the standards of IEC 62271-110 ;2009.It has been evidenced that the parameters of the substitute circuit represent a relatively severe case and cover the majority of service applications after debugging and type test. The circuit can effectively prove the ability of a circuit-breaker and contactor to switch high-voltage motors.关键词
