Embodiment 1

[0048] An embodiment of the present invention provides a detection method for a nuclear power plant main pump speed signal processing module, see figure 1 , the method includes:

[0049] S1. Connect the power cord and test jumper to connect to the self-test unit of the speed signal processing module;

[0050] S2. Switching the adjustment switch on the self-inspection unit to realize the power-on instruction self-inspection, fixed-speed self-inspection, frequency sweep mode self-inspection, channel self-inspection and threshold self-inspection of the rotational speed signal processing module.

[0051] It should be noted that before the self-test, connect the power line, power on the speed signal processing module, connect the test jumper, and connect the self-test unit of the speed signal processing module. Furthermore, different self-inspections of the rotational speed signal processing module can be realized by switching the adjustment switch on the self-inspection unit.

Abstract

The invention discloses a detection method of a rotational speed signal processing module of a main pump of a nuclear power plant. The detection method comprises: connecting a power line and a test jumper to communicate with a self-inspection unit of the rotational speed signal processing module; switching the self-inspection unit on the self-inspection unit Adjust the switch to realize the power-on instruction self-check, fixed speed self-check, frequency sweep mode self-check, channel self-check and threshold self-check of the speed signal processing module. The invention also discloses a self-inspection system of the main pump speed signal processing module of the nuclear power plant. The invention can improve the self-inspection efficiency, and the self-inspection is simple and comprehensive.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a detection method and system for a main pump speed signal processing module of a nuclear power plant. Background technique [0002] In nuclear power plants, the reactor coolant pump is the key equipment to ensure the normal operation of the nuclear power plant. The speed is an important parameter to monitor the operation status of the main pump, and the speed signal processing module is the most intuitive device for monitoring the speed of the main pump. During the operation of the main pump of the nuclear power plant, the speed signal processing module acts as the eyes of the main control room. Whether it can work normally is directly related to whether the main control room can control the current operation of the main pump (reactor coolant pump) and make correct adjustments. judge. The periodic self-inspection function of the speed signal processing module is the simpl...
