HMCXZ 20kV cable withstand voltage test equipment usually includes the following main components:
1.High voltage generator: used to generate 20kV high voltage power supply, usually using a transformer or DC high voltage generator.
2.Control system: It is used to control the output voltage and current of the high-voltage generator to ensure the safety and stability of the test process.
3.Test bench: used to support and fix the cable to be tested, to ensure the stability and safety of the cable during the test.
4.Test instrument: used to monitor and record voltage, current, insulation resistance and other parameters during the test process to ensure the accuracy and reliability of the test results.
5.Safety protection devices: including leakage protection devices, overvoltage protection devices, etc., to ensure the safety of testers and equipment.
Together, these components form a 20kV cable withstand voltage test equipment, which is used to carry out high-voltage withstand voltage test on the cable to ensure that it can work safely and reliably in practical use.
HMCXZ 20KV cable withstand voltage test operation steps:
1.Preparation: Confirm the normal working condition of the test equipment and instruments, check the appearance and wiring of the test cable.
2.Wiring: Connect both ends of the 20kv cable to the high-voltage generator and grounding device respectively.
3.Commissioning: Adjust the output voltage and frequency of the high-voltage generator to ensure that the test requirements are met.
4.Start the test: Gradually increase the output voltage of the high-voltage generator until the set withstand voltage test value is reached. During the test, observe whether the cable has abnormal conditions such as discharge and breakdown.
5.Test result recording: record the voltage value, test time, test environment temperature and other related data during the test process.
6.End test: After the test is completed, gradually reduce the output voltage of the high-voltage generator to restore the cable to normal working state.
7.Inspection & Cleaning: Check the appearance and connection of the test cables, clean the test site and equipment.
8.Test report: Generate a test report based on the test results, including test data, test methods, test environment, and other information.
