Description

Technical Field

[0001] This utility model relates to the field of withstand voltage tester technology, and more specifically, to a secondary withstand voltage tester for high-voltage power equipment. Background Technology

[0002] A puncture test is one of the main methods for verifying the overvoltage resistance of electrical appliances, equipment, installations, circuits, and electrical safety tools. It is divided into two types: power frequency withstand voltage test and DC withstand voltage test. The power frequency withstand voltage test uses a voltage that is one to several times the rated voltage of the tested equipment, but not less than 1000V. The pressurization time is: 1 minute for equipment with porcelain and liquid as the main insulation, 5 minutes for equipment with organic solid as the main insulation, 3 minutes for voltage transformers, and 10 minutes for oil-immersed power cables. The DC withstand voltage test allows for the plotting of leakage current-voltage characteristic curves by measuring the leakage current at different test voltages. Withstand voltage tests can detect localized insulation defects, moisture absorption, and aging in electrical equipment.

[0003] During the secondary withstand voltage test, the tester itself may be connected due to air breakdown, causing the tester to become energized and grounded, resulting in inaccurate test data and requiring multiple tests.

[0004] Secondary withstand voltage tests may be conducted indoors or outdoors. Indoors, an insulating board can be used to elevate the tester to ensure adequate insulation. Outdoors, if the tester cannot be adequately insulated, it may lead to high-voltage breakdown, posing a danger to the test personnel and resulting in inaccurate test results. Utility Model Content

[0005] The purpose of this invention is to provide a secondary withstand voltage tester for high-voltage power equipment, a tester that can be fixed outdoors and is easy to use.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a secondary withstand voltage tester for high-voltage power equipment, comprising:
