Zusammenfassung: | The proposed explosion-proof complete unit for controlling a three-phase cage motor contains an actuator, a remote control unit, a unit for monitoring power circuit insulation, and a program control unit. The outputs and inputs of the program control unit are connected to the corresponding outputs and inputs of the actuator and the remote control unit. The output of the insulation monitoring unit is connected to the input of the program control unit. The inputs of the insulation monitoring unit are connected to the terminals of the monitored power circuits via switching elements of the actuator. |
