The dielectric test of nuclear power valve electric devices is an important means to evaluate their electrical insulation performance. The dielectric test mainly measures the insulation resistance, leakage current, and other parameters of the device under specific conditions to determine whether it has insulation defects or potential faults. The following is the method of dielectric test of nuclear power valve electric devices:

1. Test Preparation
Test equipment: Prepare dielectric test equipment that meets the requirements, such as insulation resistance tester, leakage current tester, etc.
Test conditions: Ensure that the test environment meets the requirements of relevant standards, such as temperature, humidity, etc.
Safety measures: Take necessary safety measures, such as disconnecting the power supply, grounding protection, etc., to ensure the safety of test personnel.
2. Insulation resistance measurement
Connect equipment: Connect the insulation resistance tester to the part to be tested of the nuclear power valve electric device.
Apply voltage: Apply appropriate DC voltage according to the requirements of the equipment manual.
Read data: After applying voltage, read the insulation resistance value displayed by the insulation resistance tester.
Judgment criteria: Judge whether the insulation resistance value is qualified according to the requirements of relevant standards or technical specifications.
3. Leakage current measurement
Connect equipment: Connect the leakage current tester to the part to be tested of the nuclear power valve electric device.
Apply voltage: Apply appropriate AC or DC voltage according to the requirements of the equipment manual.
Read data: After applying voltage, read the leakage current value displayed by the leakage current tester.
Judgment criteria: Determine whether the leakage current value is qualified according to the requirements of relevant standards or technical specifications.
IV. Matters needing attention
Selection of test voltage: The test voltage should be determined according to the rated voltage and insulation level of the nuclear power valve electric device.
Control of test time: The test time should be determined according to the requirements of relevant standards or equipment manuals to ensure the accuracy of the test results.
Recording of test results: The various parameters and results during the test process should be recorded in detail for subsequent analysis and evaluation.
Implementation of safety measures: During the test process, the safety operating procedures should be strictly followed to ensure the safety of the test personnel.
V. Post-test processing
Data analysis: Perform data analysis on the test results to determine whether the insulation performance of the nuclear power valve electric device is qualified.
Troubleshooting: If the insulation performance is found to be unqualified, troubleshooting and repair should be carried out in time.
Test report: According to the test results, write a test report to record the test process, results, and conclusions.
In summary, the dielectric test of nuclear power valve electric devices is an important means to ensure their electrical insulation performance. By strictly following the test methods and precautions, the accuracy and reliability of the test results can be ensured.
