Design of automatic detection device for nuclear reactor rod position detectors
The rod position detector in nuclear power plants is an important equipment for detecting the status of control rods in nuclear reactors.Regular inspection of rod position detectors is a key link in the operation and maintenance of nuclear power plants.However,there are a large number of on-site rod position detectors,which are time-consuming and laborious to manually detect,and there is a risk of human error.This article provides a detailed introduction to an automatic detection device for rod posi-tion detectors,which includes a main control module,a power system,a coil resistance measurement module,an insulation resistance measurement module,a signal switching array,and other modules.The device can automatically complete the testing of three rod position detectors simultaneously.Tests have shown that using an automatic detection device for detection results in a detection error of less than 1％compared to a high-precision multimeter,and the detection efficiency is improved by more than 50％.
