Problems solved by technology

In the prior art, instruments such as withstand voltage testers and insulation resistance testers are used to measure the insulation between coils; instruments such as multimeters are used to measure point by point to obtain the direct resistance value; however, the driving mechanism of nuclear power plants requires simultaneous testing of direct resistance and insulation. Traditional measuring equipment can only measure DC resistance and insulation separately
In addition, traditional nuclear power plant reactors are often equipped with hundreds of identical driving mechanisms at the same time, and there are a lot of radioactive substances. Therefore, if the nuclear power plant drive is tested by a withstand voltage tester and an insulation resistance tester, it will not only consume a lot of manpower. ,Time costs
And the safety of staff cannot be guaranteed

Description

technical field [0001] The invention relates to the technical field of nuclear power plant component testing, in particular to an insulation and direct resistance tester for a driving mechanism of a nuclear power plant, which is used for measuring the insulation coefficient and direct resistance parameters between coils of the driving mechanism of a nuclear power plant. Background technique [0002] The driving mechanism of nuclear power plant is a device used to control the position of nuclear fuel control rods. The start-up, power regulation, compensation of residual reactivity, shutdown and accident emergency shutdown of the power plant are all realized by changing the position of the control rods. Among them, the driving mechanism of a nuclear power plant is generally composed of five major components: a pressure-resistant casing, an electromagnetic assembly, a moving assembly, a driving rod, and a position indicator. Among them, the electromagnetic component and the p...
