HMCXZ cross-linked cable withstand voltage test device is a device used to test the withstand voltage performance of cross-linked cable insulation materials. It usually consists of a high-voltage generator, a test transformer, a withstand voltage chamber, a control system, and other parts.
A high-voltage generator is a device used to generate high-voltage power, usually using a transformer or a DC high-voltage generator. The test transformer is used to transfer the high-voltage power to the cross-linked cable being tested for hipot testing. A pressure chamber is a space where cross-linked cables are placed and tested, and are usually sealed for safety. The control system is used to control the test process, monitor the test parameters, and record the test results.
During the test, the cross-linked cable to be tested is placed in a pressure-resistant chamber, and the high-voltage power supply is transmitted to the cable through the test transformer, and the high-voltage voltage is continuously applied until the set test parameters are reached or breakdown occurs. Through the test results, the voltage resistance of the cross-linked cable insulation material can be evaluated to ensure its safety and reliability during use.
The cross-linked cable withstand voltage test device is widely used in power systems, communication systems, railways, petrochemical and other fields, and is one of the important equipment to ensure the quality and safety of cross-linked cables.
HMCXZ cross-linked cable withstand voltage test device operation steps:
1.Preparation: Check whether the various parts of the withstand voltage test device are in good condition and confirm that the cables have been connected to the test device.
2.Set parameters: According to the specifications and requirements of the cable, set the parameters of the withstand voltage test device, including voltage, current, time, etc.
3.Safety checks: Ensure the safety of the test site and the surrounding environment, and check for the presence of combustible materials or other hazards.
4.Connecting cables: Connect the cable to be tested to the withstand voltage test device to ensure that the connection is firm and not loose.
5.Opening device: According to the requirements of the operation manual, turn on the power supply of the withstand voltage test device, and preheat and debug.
6.Start the test: After confirming that everything is ready, start the hipot test according to the set parameters, and monitor the voltage, current, and time during the test.
7.Monitoring results: During the test, observe the condition of the cable in time to check whether there are any abnormal phenomena, such as leakage, overheating, etc.
8.End the test: According to the set time or test results, end the withstand voltage test, turn off the power of the test device, and disconnect the cable.
9.Tidying up: Clean and tidy up the test equipment and the surrounding environment to ensure the safety and cleanliness of the equipment and site.
10.Record the results: record the parameters and results in the test process, including the date of the test, cable specifications, test results and other information.
