The Development of Integrative and Intelligent Controlling Protector of Electromotor

At present the control and protection of relay of electromotor uses combined circuit, which has the limitation of weak control and faulty protecting function .This paper provides a equipment having integration of control protection break-down memory and functional display. It has perfect protecting effect and nicer protecting characteristic It has the function of the display of charge state and indication of regulation ; it can protect magnetizing coil of contactor and main contacting dot well, it can make contactor function quietly and frugally it keep the memory of diversified malfunction while electromotor is functioning ,in order to make user to eliminate malfunction rapidly its controlling circuit is easy , it has merits of saving energy markedly.
