Background
According to the statistics of the power grid, partial discharge is an important cause of the final insulation breakdown of high-voltage electrical equipment and is also an important sign of insulation degradation. The partial discharge refers to a discharge that occurs between the electrodes but does not penetrate the electrodes, and is a phenomenon in which repeated breakdown and extinction occur under the effect of high electric field strength due to a weak point inside the insulation of the device or a defect caused during the production process. It is expressed as the breakdown of gas in the insulation, the local breakdown of solid or liquid medium in a small range, or the local breakdown discharge caused by the concentration of the field intensity at the edge and sharp corner of the metal surface. This discharge is limited to causing only isolated local short-circuiting bridges between conductors without forming conductive paths. Each time, partial discharge has some influence on an insulating medium, slight partial discharge has little influence on insulation of power equipment, but if partial discharge continuously occurs in insulation of electrical equipment under operating voltage, the weak discharge generates an accumulation effect to gradually deteriorate dielectric property of the insulation and enlarge local defects, and finally the whole insulation is broken down. Therefore, the monitoring of the equipment in operation needs to be enhanced, and when the partial discharge exceeds a certain degree, the equipment is taken out of operation and is overhauled or replaced. The partial discharge monitoring device is arranged at a corresponding position in the prior art in a wall-mounted mode and is not stable or is fixedly arranged on monitored equipment through screws, so that the partial discharge monitoring device is inconvenient to disassemble.
