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...
