Problems solved by technology

In the process of ascending heights, inspectors should firmly attach the probe to the designated position such as the surface of the GIS shell, which is labor-intensive, time-consuming and labor-intensive, and high-altitude operations are highly dangerous. It is impossible to completely avoid the probe when installing and removing the probe. Collision with the equipment shell can easily cause damage to the probe

Abstract

The invention discloses an improved ultrasonic partial discharge detection device, which improves the working efficiency in the partial discharge detection process of GIS equipment, reduces the laborintensity and ensures the personal safety. The device comprises a partial discharge sensor used for detecting GIS equipment and a partial discharge host. The partial discharge sensor is adjusted to anangle attached to the surface of the GIS equipment through an adjusting assembly; and the adjusting assembly is connected with an insulating rod. The bottom of the insulating rod is installed on a fixed chassis, the fixed chassis comprises a base, two adjusting baffles are symmetrically arranged on the base, sleeves are installed on the adjusting baffles in a hinged mode, and the bottom of the insulating rod is inserted into the sleeves.

Description

technical field [0001] The invention relates to an ultrasonic partial discharge detection device, which is specifically used for the partial discharge detection of GIS equipment. Background technique [0002] In recent years, GIS equipment has attracted much attention because of its compact structure, good insulation performance, high reliability, strong safety, strong environmental adaptability, small footprint and convenient installation, and is widely used in power systems. Part or all of the electrical components in the GIS equipment are enclosed in a metal casing, the structure is airtight, and the internal electric field is relatively concentrated. When there are defects such as corona, free metal particles, protrusions or burrs of conductors or contact electrodes, and floating potentials, partial discharges of equipment will be caused. If they cannot be detected and processed in time, the insulation performance will be severely damaged, and eventually equipment failur...
