rpi rod position probe coil test system and method

Abstract

The present invention discloses a RPI rod position probe coil testing system and a RPI rod position probe coil testing method. The RPI rod position probe coil testing system comprises: an operation software for sending a measurement switch signal; an inputting and outputting unit for sending a measurement command according to the measurement switch signal, collecting parameter measurement results and outputting to the operation software; an integrated control unit for outputting a position identification command according to the measurement command and feeding back a trigger signal to the inputting and outputting unit; and a parameter measurement unit connected to the primary coil, the auxiliary coil and the secondary coil on at least a RPI rod position probe, and used for measuring the resistance data and the insulation data of each coil according to the position identification command and outputting the parameter measurement results to the inputting and outputting unit. With the system and the method of the present invention, the parameter measurement of the parameter measurement unit is controlled by the integrated control unit, such that the inputting and outputting unit collects the parameter measurement results so as to effectively improve the reliability and the consistency of the on-site data, avoid the data distortion caused by human error, and shorten the overhaul working hour and the manpower investment.

Description

Technical field [0001] The invention relates to the technical field of a rod control system for a million-kilowatt advanced pressurized water reactor nuclear power unit, in particular to an RPI rod position probe coil testing system and method. Background technique [0002] The RPI rod position probe of the RGL system is located on the large reactor cover. It is the only device that reflects the true rod position of the control rod, and also belongs to the CCM equipment of the power station. During each cycle of overhaul, the resistance and insulation test results of the RPI probe coil are important data reflecting the status of the RPI probe coil and its related cables. The RPI rod position probe includes a primary coil, an auxiliary coil and a secondary coil. The secondary coil includes A, B, C, D, and E coils, that is, each RPI rod position probe has a total of seven coils. The RPI coil is measured once during each cycle of downward and upward cycles. The amount of data that ...

Problems solved by technology

[0003] Technology: Due to the differences in the tools borrowed each time, the reading habits of the executives, and the operating habits, the data consistency of each overhaul is poor, and the feasibility of the historical data of the equipment is reduced.

[0004] Quality: Members of each measurement working group need to work continuously and record more than 600 data, and on this basis, carry out data processing and standard judgment. In the case of huge workload and data volume, it cannot be completely avoided from the perspective of human behavior possible omissions

[0005] Construction period: Because the insulation and resistance measurement of the RPI probe is currently performed manually, the required construction period is long, and a slight abnormality in the work may delay the critical path of overhaul
