Zusammenfassung:	The invention provides a method for reducing electric heating resistance-inductance load harmonic generation and current impact. The method for reducing electric heating resistance-inductance load harmonic generation and current impact comprises the following steps that the secondary side of a circuit breaker QF is connected into the input terminal of a power adjusting element (SSR or SCR) main circuit, and then the output terminal of the power adjusting element main circuit penetrates through an alternating current transformer TA to be connected with the input terminal of a main contact of an alternating current contactor KM; a secondary signal of the alternating current transformer TA is connected with an alternating current ammeter PA, and the output terminal of a main contact of the alternating current contactor KM is connected with one end of a thermocouple (heating element). According to the method for reducing electric heating resistance-inductance load harmonic generation and current impact, control o
