Partial discharge is an important phenomenon in high-voltage cables. It refers to the discharge phenomenon generated in the local range of the cable insulation under high voltage, referred to as partial discharge; partial discharge is often caused by the production process or internal defects of the cable insulation, including corona discharge, internal cavitation discharge, surface discharge, etc. In order to prevent the high-voltage cable discharge from causing harm to people, it is necessary to conduct discharge detection on the high-voltage cables used.

The top ends of the two sliders 7 are fixedly connected to the bottom ends of the two movable vertical plates 2 respectively. A threaded rod 8 is rotatably connected inside the slide groove 6. One end of the threaded rod 8 passes through the slider 7 and extends into the adjusting groove 9. The threaded rod 8 and the slider 7 are connected by threads.

A second bevel gear 12 is fixedly arranged at the top end of the adjusting telescopic rod 10. The second bevel gear 12 is arranged between the bottom ends of the two first bevel gears 11 and meshes with each other between the two first bevel gears 11.

[0031] A base 16 is provided at the bottom of the support plate 1, and the bottom end of the adjustable telescopic rod 10 is rotatably connected to the top of the base 16.
