Switch calibration method and switch calibration device applied to nuclear power station float liquid level meter

Abstract

The invention discloses a switch calibration method applied to a nuclear power station float level meter and a switch calibration device applied to the nuclear power station float level meter. The switch calibration method comprises the following steps: receiving and storing a preset volume of to-be-tested liquid; when a switch verification signal is received, injecting the to-be-tested liquid into or discharging the to-be-tested liquid out of the nuclear power station buoy liquid level meter within preset time, and after a pressure sensor is adopted to detect the liquid pressure and the liquid level of the nuclear power station buoy liquid level meter, converting the to-be-tested liquid into sampling current to be output; comparing the sampling current with a preset current to obtain a comparison result; and judging and displaying the on-off operation information of the float level meter according to the comparison result. According to the embodiment of the invention, the volume information of the to-be-tested liquid in the nuclear power station float liquid level meter is converted into the current information, so that the operation state of the nuclear power station float liquidlevel switch is automatically verified, time and labor are saved, and the detection precision of the operation state is relatively high; and the personal safety of technicians in the checking processof the float level switch of the nuclear power station is ensured.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant detection, and in particular relates to a switch verification method applied to a buoy liquid level gauge of a nuclear power plant and a switch verification device applied to a buoy liquid level gauge of a nuclear power plant. Background technique [0002] With the continuous development of the power system, nuclear power technology has become the main development direction of the power system. Compared with coal power generation or hydropower generation, the use of nuclear power for power generation not only has high power generation, but also has low power generation costs and environmental pollution. Therefore, nuclear power has become the main power supply energy for some large cities in my country; the principle of power generation of nuclear power plants is to use the heat released by nuclear fission to generate corresponding electric energy; therefore, in each nuclear power reacto...
