Inspection and calibration device for nuclear power station reactor core liquid level monitoring system

The invention belongs to the technical field of nuclear power station reactor core liquid level monitoring and particularly relates to an inspection and calibration device for a nuclear power station reactor core liquid level monitoring system. The device comprises a calibration simulator, a reactor core liquid level monitoring device, a power supply, a connecting mechanism and a plurality of groups of leads, wherein the reactor core liquid level monitoring device is clamped in the connecting mechanism, a power supply is further arranged in the connecting mechanism, and the power supply is located above the reactor core liquid level monitoring equipment; and a reactor core liquid level monitoring system is mounted in the reactor core liquid level monitoring device. The device is advantaged in that a problem that no fixed module power supply switch exists on the cabinet side of the reactor core liquid level monitoring system is solved, the electric shock risk during operation is reduced, module damage and overall scrapping caused by frequent plugging operation are avoided, automatic timing start and stop of nuclear power plant reactor core liquid level monitoring are achieved through the timer, and practicability is higher.
