Abstract: Present paper main introduction asynchronous motor each kind of protection principle. Through explaining its protection direction to the asynchronous motor basic active status statement. Effective electric motor protection method and equipment, Can’t only implementate to each kind of breakdown reliable protection which possibly appears to the electric motor. But also can fully display the electric motor the overload capacity, Which reduces the economic loss in the production process, Enhance one of economic efficiency essential solution questions.
The intelligence asynchronous motor synthesis protector using the P87LPC76XOTP monolithic realized the intellectualized design, the electric current examination is simple, the parameter installation was convenient, movement stable reliable, had the over-load protection, idling energy conservation many kinds of functions, also with main circuit connection simple convenient.
Keywords: protector, overload, idling, self regulating
