A partial discharge automatic detection device, system and method

Abstract

The invention discloses a partial discharge automatic detection apparatus, system and method. The apparatus comprises a robot body; and an extension module and a control module that are arranged thereon. The robot body comprises a horizontal movement module and a vertical lifting movement module which enable the extension module to move in a horizontal direction and a vertical direction respectively. The extension module performs an action of extending outward relative to the robot body, and drives a detection module disposed at the tail end of the extension module to move according to a control instruction sent by the control module until the detection module is attached to the surface of a detected device. The robot body is provided with an auxiliary positioning module thereon to mark the surface of the detected device, and the control module corrects the movement trajectory of the extension module according to the deviation between the marked point and a target point, so as to realize the automatic detection of the partial discharge of the position of each target point. According to the invention, the problems and defects can be discovered in time and the resulting huge loss canbe avoided.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a partial discharge automatic detection device, system and method. Background technique [0002] At this stage, my country's power system puts forward higher and higher requirements for the quality of electric energy, not only to ensure stable and reliable power supply, but also the safety of power supply is also an important requirement. In the power system, metal-enclosed switchgear is widely used. Therefore, whether the switchgear is stable and reliable is the most important thing. During the operation of electrical equipment, due to high temperature, voltage, vibration and other chemical effects, it will make it insulated. If the performance is reduced, partial discharge will occur, and at the same time, the deterioration of insulation will be accelerated, which will cause greater economic losses to the power system. [0003] For a long time, the partial discharge de...

Problems solved by technology

[0013] In order to solve the above problems, the present invention proposes a partial discharge automatic detection device, system and method. The present invention uses a three-dimensional laser radar to realize the acquisition of the environmental information of the robot in the switch cabinet room, and calculates the need to carry out by analyzing the acquired environmental information. The location of the detection point for partial discharge detection can reduce labor intensity and substation operation and maintenance costs, and can detect problems and defects in time to avoid huge losses
