Abstract

The invention provides a simulated partial discharge detection device for a switch cabinet. The simulated partial discharge detection device comprises a power supply module, a switch cabinet module and an electrical pulse partial discharge detection module, wherein the switch cabinet module consists of a cabinet body, an ultrasonic sensor, a high-frequency sensor, a TEV (Transient Earth Voltage) sensor, a video monitoring system and a discharge model, the power supply module outputs a stable voltage to the discharge model, the discharge model simulates the partial discharge phenomenon of the switch cabinet in the cabinet body, the ultrasonic sensor, the high-frequency sensor and the TEV sensor collect various parameters of the discharge model during simulating the partial discharge phenomenon of the switch cabinet, and sends the collected parameters to the electrical pulse partial discharge detection module, and the video monitoring system collects the image data during the partial discharge process of the discharge model. The discharge model can accurately simulate the partial discharge phenomenon of the switch cabinet, all sensing equipment accurately collect the parameters, and then the electrical pulse partial discharge detection module analyzes the parameters, so that complicated simulation detection operations are not required, the detection efficiency is high and various defects can be widely simulated.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a detection device for partial analog discharge of a switchgear. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, motor magnetic switches, various AC contactors, etc. Some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc., and some also have low-cycle load shedding to ensure the main equipment. . [0003] In the normal operation of the power grid, there will be partial discharge of the switchgear. At this time, it is necessary to detect the partial discharge of the switchgear, and make a corresponding treatment plan according to the detection results to ensure the normal and safe operation of the power gri...
