The invention discloses a partial discharge detection device of a high-voltage cable. The partial discharge detection device comprises a partial discharge sensor, a trigger module, a multi-channel acquisition module, a power supply module and a main control module. The partial discharge sensor is in communication connection with the trigger module; the trigger module is in communication connection with the main control module; the main control module is in communication connection with the multi-channel acquisition module; the multi-channel acquisition module is in communication connection with the partial discharge sensor. The power supply module provides power for all the module devices; the partial discharge sensor detects a partial discharge signal of a high-voltage cable, and after the trigger module determines that the detected discharge signal meets a certain condition, the trigger module transmits the discharge signal to the main control module so as to carry out partial discharge diagnosis, defect identification, fault positioning and comprehensive diagnosis processing. According to the invention, the technical problem that both online partial discharge detection equipment and portable partial discharge detection equipment in the prior art cannot meet the requirements of customers is solved.
Description
technical field [0001] The invention relates to the field of high-voltage cable partial discharge detection, in particular to a high-voltage cable partial discharge detection device. Background technique [0002] With the rapid development of urban economy, the cable rate of urban power grid continues to rise, and the total amount of high-voltage cable equipment maintains an average annual growth rate of 10%. The safe and stable operation of high-voltage cable network is very important to the entire power grid. On-line partial discharge monitoring of cables in operation can effectively grasp the operation status of cables, timely discover hidden dangers of insulation, and ensure their reliable operation. [0003] Based on the above-mentioned technical background, the technical problems to be solved by the present invention are as follows: [0004] Question 1: Generally, online partial discharge detection equipment is passive measurement, with a large amount of partial disch...
