Method for measuring leakage current of vanadium fixed detector in reactor

The invention belongs to the technical field of leakage current measurement, and particularly relates to a method for measuring the leakage current of a vanadium fixed detector in a reactor, which comprises the following steps of: 1, connecting a known resistor in a detection loop in series; 2, calculating the leakage current and the leakage correction factor of the vanadium detector in the operation period; 3, counting and analyzing a leakage current correction factor range; step 4, analyzing whether the leakage current correction factor of the same detector changes along with changes of a random group, a cycle and a power platform; and 5, confirming a power platform for carrying out a leakage correction factor measurement test and the number of times of measurement. According to the method, the leakage current can be accurately and efficiently measured, the corrected current value can accurately represent the true value of the detector signal, meanwhile, the requirement of a vanadium detector leakage correc
