摘要（英）：

The invention provides a design method for input inductive load control parameters of a compound switch. The control parameters include the initial two-phase triggering angle and the three-phase triggering angle. The method includes the following steps of calculating the initial two-phase thyristor triggering angle, calculating the third-phase thyristor triggering angle, closing a three-phase vacuum circuit breaker, and turning off an ABC three-phase thyristor. According to the design method for the input inductive load control parameters of the compound switch, by means of the compound switch formed by connecting the thyristor and the vacuum circuit breaker in parallel, rapid input control over a transformer and induction motor loads is achieved, and the aim of restraining the impact current when the inductive load is rapidly input is achieved.
