| Abstract: | The integrated control cabinet monitors the real-time load current of air conditioning unit by the PLC.At the same time,the dual protection,which is composed of the thermal relay and over-current relay,diagnoses and protects promptly effectively the compressor,overload of the air pre-heater,over-current,unbalance of the three-phase current, breakdown of lack phase. In addition, the breakdown information is displayed on the touch screen which facilitated the train attendant to handle the breakdown of air conditioning unit. |
