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

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant core liquid level monitoring, and in particular relates to an inspection and calibration device for a nuclear power plant core liquid level monitoring system. Background technique [0002] The inspection and calibration device of the core liquid level monitoring system is mainly used to solve the quick inspection of the faulty modules in the cabinet of the daily core liquid level monitoring system, the calibration and adjustment of the working parameters of the modules during the overhaul, and the inspection of the core liquid level monitoring system And the calibration device can quickly and intuitively judge the fault point of the cabinet operation module in the field application, and can quickly carry out the calibration work of the module during the overhaul. The reliability of safe operation and the reduction of its out-of-run time have significant economic and social benefits. ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention proposes an inspection and calibration device for the nuclear power plant core liquid level monitoring system to solve the problem that the existing core liquid level monitoring system inspection and calibration device needs to be installed in the core liquid level monitoring system In the cabinet, and there is no fixed module power supply switch, during the inspection, it is necessary to perform power supply and power-off operations by plugging and unplugging the fixed plug. There is a risk of electric shock during operation. Parts are damaged, or even scrapped as a whole, and the practicability is poor, and the inspection and calibration device of the existing core liquid level monitoring system is completely manually operated when starting and stopping, and it is impossible to realize the automatic stop of the inspection and calibration device of the core liquid level monitoring system, which is not practical. good question
