What are the operations before the Volvo generator starts? Now let me share with you:
        1. Open the grounding switch at the outlet of the Volvo generator.
        2. Close the isolating switch of the Volvo generator outlet.
        3. Check that the micro-positive pressure device of the sealing mother is running normally.
        4. Check that the fuses of the voltage transformer of the Volvo generator are normal, and push the handcart of the voltage transformer at the generator outlet into the working position.
        5. Close the neutral point isolating switch of the Volvo generator.
        6. Put on the excitation power switch.
        7. Send the Volvo generator to control and protect the DC power supply, and the experiment sound and signal are correct.
        8. Send the synchronous screen DC control power supply.
        9. Turn on the start and stop protection of Volvo generator.
        10. Send the AC power supply and DC power supply to the Volvo generator transmitter screen.
        11. Send all the miniature circuit breakers in the Volvo generator voltage transformer cabinet.

        12. Volvo generator outlet circuit breaker, isolating switch and neutral point isolating switch, all voltage transformer handcarts are in correct position, the indication is correct, no abnormality and alarm information exists; the position displayed by each indication signal and automatic device on the dcs screen is the same as that of the automatic device. The device actually matches. There is no abnormality in dcs and there is an alarm signal.
