1: Waterway circulation system
The cooling water enters the intercooler of the air compressor through the pipeline to cool and cool the first-stage compressed exhaust gas, and then enters the aftercooler to cool the exhaust gas, and the other cooling water inlet pipe passes through the two sets of heat exchangers above the main motor Cooling the motor winding, there is also a way to cool the oil cooler.
2: Power distribution system
The air compressor is a 2000kW high-voltage motor (10kV), which is started at full voltage. The control cabinet is indoor AC and metal armor draw-out switch equipment. The switch equipment is composed of a fixed cabinet and drawable parts, that is, a handcart. The purpose of control, protection and monitoring has the function of "five preventions".
3: Screen protection system
The central signaling device is divided into two kinds of accident signals and warning signals. The main task of the accident signal is to be able to send out an audible signal in time when the circuit breaker accidentally trips, and make the corresponding circuit breaker light position signal flash. The main task of the pre-announcement signal is to send out an audible signal instantaneously or delayed when the operating equipment is abnormal, and make the light plate display the content of the abnormal phenomenon.
