The large scale advanced pressurized water reactor protectable main coolant pump fire protection system of claim 11, wherein: after the starting device (11) starts the spraying facility, the normal trigger of the starting device (11) provides a normal starting signal of the fire-fighting system.
17. The large scale advanced pressurized water reactor protectable main coolant pump fire protection system of claim 11, wherein:
the system comprehensive situation perception (10) is comprehensively generated by a leakage signal of the driving power source (1) and a water source storage condition signal of the self-contained fire water tank (5) under a normal condition; wherein, the leakage signal is normal when not appearing, and the water source reserve condition signal water level is normal when not breaking through the setting value; when the two signals are normal, the fire fighting system is in a normal usable state; if any signal is abnormal, a fault alarm that the fire fighting system is unavailable is sent out;
when a fire system needs to act in case of fire, the system starting state feedback (14) is generated by comprehensively generating a gas flow signal of the driving power source (1) and a water source storage condition signal of the self-contained fire water tank (5) after the starting device starts a spraying facility; the driving gas flow signal of the driving power source (1) is normal after reaching a setting value, and the water source reserve condition signal is normal when the water level does not break through the setting value; if the water level of the water source storage condition signal is lower than the setting value, an alarm signal is sent out;
after the starting device (11) starts the spraying facility, the normal trigger of the starting device (11) provides a normal starting signal of the fire-fighting system;
the signals all indicate that the fire fighting system is normally started; if any signal is abnormal, a fault alarm that the fire fighting system is not normally started is sent out.
18. The large scale advanced pressurized water reactor protectable main coolant pump fire protection system of claim 17, wherein:
the leakage signal of the driving power source (1) is provided by the combination of the gas storage bottle (13), the leakage detector (2) and the diaphragm (3), and the leakage signal is normal when not occurring;
a water source storage condition signal of the self-contained fire water tank (5) is provided by a liquid level detector (6), and the water level is normal when the water level does not break through a setting value;
the driving gas flow signal of the driving power source (1) is provided by the gas storage cylinder (13) and the flow detector (4), and the driving gas flow signal is provided normally after the setting value is reached.
