Description

Technical Field

[0001] This utility model belongs to the field of safety tools and equipment technology, and specifically relates to an automatic wiring device for high-voltage testing of safety tools and equipment. Background Technology

[0002] In modern power systems, safety tools play a crucial role, not only in protecting the personal safety of power workers but also in ensuring the stable operation of the power system.

[0003] Safety tools and equipment may fail due to aging, wear, or improper operation during use, thus losing their protective function. Therefore, it is necessary to conduct high-voltage tests regularly to check the insulation strength of safety tools and equipment and ensure their effectiveness and reliability.

[0004] Currently, high-voltage testing of safety equipment generally uses a test transformer shared by multiple testing devices. For rational layout and ease of use, a high-voltage busbar needs to be installed in the test chamber. Each testing device can connect its high-voltage input rod to the nearest high-voltage busbar to receive high voltage. In addition, there are numerous rods for connecting the high-voltage input of the test transformer to the high-voltage busbar, as well as rods for grounding after the test, resulting in a large number of rods. Each rod needs to be manually connected as needed, increasing the workload of operators. At the same time, since the test voltage and withstand voltage time of different testing devices are different, only one type of high-voltage testing device's high-voltage input rod is allowed to be connected to the high-voltage busbar for each test. At the same time, it must be ensured that the grounding rod is removed. If the rod is connected incorrectly, it can easily lead to test interruption and problems. In severe cases, the high-voltage surge may even damage the test transformer or testing equipment.
