Description

Technical Field

[0001] The utility model relates to the technical field of electric high-voltage testing tools, in particular to an electric high-voltage testing hook. Background Art

[0002] High-voltage testing is a method of testing the electrical performance of electrical equipment using high voltage. It aims to analyze and determine various performance indicators, eliminate potential defects, and promptly detect and address equipment aging and degradation issues, thereby ensuring the reliability of equipment operation. When testing high-voltage electrical equipment, the inspector needs to use the corresponding high-voltage test hook to connect the test line in the high-voltage test instrument to the high-voltage electrical equipment under test. After the test line of the high-voltage test instrument is connected to the high-voltage electrical equipment under test, the high-voltage test is performed.

[0003] Announcement No. "CN206399985U" provides an electric high-voltage test hook, which is hooked through an insulating rod set on a connector, uses a lifting device to drag the connector, and connects the test line connected to the connector and the high-voltage end component to be tested to form a test loop. The tester conducts testing. The tester does not need to climb the high-voltage power equipment tower and frequently connect the test clip of the high-voltage test instrument to the high-voltage power equipment to be tested. The tester can test the high-voltage power equipment while standing on the ground, reducing the frequent test operations of connecting the test clip of the high-voltage test instrument to the high-voltage power equipment to be tested. This greatly improves the testing efficiency of high-voltage power equipment and avoids safety hazards.

Secondly, the connector and the connecting rod in the electric high-voltage test hook do not have the ability to swing adjustment, and cannot adapt to the high-voltage power equipment and test lines to be tested with different wiring angles. Therefore, the scope of application needs to be further improved. Utility Model Content
