[0002] High-voltage testing devices, as a powerful tool in the field of electrical safety, play a crucial role in accurately testing the insulation performance of high-voltage electrical equipment to ensure its safety and reliability. They not only ensure quality control before new equipment is put into operation, but also promptly detect and eliminate faults during equipment maintenance, and effectively prevent electrical accidents during regular inspections. Their applications are wide-ranging, covering switchgear and transformer testing in power systems, high-voltage equipment testing in rail transit systems, and high-voltage equipment testing such as generators and motors in industrial production.

[0003] Chinese patent discloses a high-voltage voltage testing device (authorization announcement number CN219695287U). The main body of the voltage testing device is set inside the loading mechanism. It is hung on the high-voltage power line for testing by hook. This avoids the user's arm pain caused by moving the telescopic rod for a long time, and can test the high-voltage power line more quickly. However, it cannot adjust the angle of the loading mechanism, which makes it inconvenient to test some corner positions. Utility Model Content
