Switch cabinet partial discharge simulation device based on automatic control

Abstract

The invention discloses a switch cabinet partial discharge simulation device based on automatic control. The device comprises discharge electrode models, electric actuating mechanism and control unit,a flexible buffer, a camera and a dustproof cover, wherein the multiple discharge electrode models are correspondingly arranged above a plurality of busbars; the electric actuating mechanism and control unit comprise a linear module, an encoder and a controller; the linear module comprises a stepping motor and a lead screw sliding block which is driven by the stepping motor to move linearly; thecorresponding discharge electrode model is connected with the lead screw sliding block; the linear module drives the corresponding discharge electrode model to move up and down through the lead screwsliding block; the encoder is connected with the stepping motor and used for feeding back a position signal of the corresponding discharge electrode model; the flexible buffer is mounted on a copper bar electrode or the corresponding discharge electrode model; the camera is mounted on a cabinet body behind a busbar chamber; and the dustproof cover is arranged above the electric actuating mechanismand control unit in a covering manner. According to the device, various fault types in an operation state of a switch cabinet can be simulated, synchronous addition of interference signals can be realized, and inconvenience of manually adjusting the discharge models is avoided.

Description

technical field [0001] The invention belongs to the technical field of high-voltage discharge simulation, in particular to a partial discharge test simulation device for a switch cabinet. Background technique [0002] The switch cabinet is one of the main equipment of the power distribution system, and its operating status has a significant impact on the reliability of the power distribution system. The consequences of the failure of switchgear equipment in the distribution network are very serious. The direct harm is the damage of the lines and equipment protected by the electrical equipment, and the loss of electricity; Area blackouts reduce power supply reliability. However, the distribution network equipment has a large number and wide distribution, and the working environment is harsh; the insulation materials of the switchgear in the power distribution system have been exposed to high temperature, high voltage, vibration, oil, moisture and chemical substances for a lo...

AI Technical Summary

Problems solved by technology

[0003] There are various types of partial discharge. In order to let the operation and maintenance personnel to grasp the knowledge of partial discharge as soon as possible, improve the detection level of partial discharge, and apply it to practice, there are many switchgear partial discharge simulation devices on the market, but all of them are It is a manual mode, and it is necessary to manually shake the joystick to adjust and switch the electrodes, so there are problems such as inconvenient use, danger of the test personnel mishandling the electrodes during the boost test, inconvenient switching electrodes during the skill assessment, and students are easy to see the test model, etc.
