Abstract

The invention relates to a partial discharge detection system and a partial discharge detection device. The partial discharge detection device includes a support, a reflective plate, an antenna and a video connector, wherein the reflective plate is arranged on the support, and the reflective plate is used to reflect local discharge signal. The antenna is arranged on the reflector plate for collecting partial discharge signals. RF connectors connect to antennas and are used to connect signal processing equipment. The above-mentioned partial discharge detection device can perform non-contact detection of partial discharge of high-voltage cable lines, and utilizes the characteristic that the intensity of partial discharge signal will rapidly decay with distance, and detects partial discharge signals at different positions by moving the partial discharge detection device. Then compare the intensity of the partial discharge signal at different positions, and the position with the strongest partial discharge signal intensity is the position of the partial discharge source.

Description

technical field [0001] The invention relates to the technical field of grid line maintenance, in particular to a partial discharge detection system and a partial discharge detection device. Background technique [0002] Partial discharge refers to the discharge phenomenon that occurs between the electrodes but does not penetrate the electrodes. It is due to the weak current inside the insulation of the equipment or the defects caused by the production process, and the phenomenon of repeated breakdown and extinguishment occurs under the action of high electric field strength. Partial discharge under the action of high-strength electric field is a common problem in high-voltage insulating media. Although partial discharge generally does not cause penetrating breakdown of insulating media, it can cause local damage to dielectrics, especially organic dielectrics. If the partial discharge exists for a long time, under certain conditions, it will lead to the deterioration of the i...
