1. Automatic starting and automatic switching of power supply: when the mains is interrupted, the mains switching circuit immediately cuts off the mains power supply circuit. At the same time, the mains monitoring circuit makes the starting motor run through the self-starting controller, so as to start the diesel generator set. After the success of the starting, lubricating oil pressure rise, when the oil reaches the specified value, starting successful oil pressure sensor, through to oil road control circuit of electromagnetic valve, the solenoid valve open the acc the oil cylinder, the pressure of diesel engine lubricating oil driving oil cylinder piston, drive the throttle lever to the up direction, at the speed limit under the action of the controller, the diesel engine working in the rated speed. At this point, under the action of the automatic voltage regulator, the generator outputs the rated voltage. The generator switch circuit is then switched on and the diesel generator starts to supply power to the load.
2. Automatic shutdown after the restoration of the mains: after the restoration of the mains, the diesel engine power supply circuit will be cut off under the action of the mains monitoring circuit, and then the mains switching circuit will be put into operation, and the load will be powered by the mains. At the same time, the self-starting controller makes the shutdown electromagnet action, control the diesel engine throttle, diesel generator first low speed operation, and then automatic shutdown.
3, fault shutdown and alarm: in the operation process of the unit, the cooling water outlet temperature reaches 95℃±2 hours, the temperature controller sends out sound and light alarm signal through the system controller and cuts off the load, at the same time, the shutdown electromagnet action, the diesel generator stops running.
4. During the operation of diesel generator, when the oil pressure of lubricating oil is lower than the specified value, the contact of the low oil pressure alarm sensor is closed, and the controller sends out sound and light alarm signal through the display alarm device, and at the same time cuts off the oil mechanical and electrical switching circuit, and then the electromagnet runs and the diesel generator automatically stops. When the unit speed exceeds the rated speed, the high cycle relay in the monitoring circuit of the oil machine will operate and the diesel generator will stop automatically.
