| Abstract: | In integrated mechanization roadheader,a motor protector has been designed for two purposes.One is for three motors to provide protection,such as overcurrent,overload,locked rotor,open-phase,overheat,electric leakage,and another is for 220V,127V and 36V electronic control power supply loop.And this protector has switch signal and RS-485 interface,so it is very easy to become integrated mechanization roadheader electronic control system with PLC. |
