Problems solved by technology

The problems of this method are: 1. It takes a long time to confirm the fault point; 2. The parts need to be operated and disassembled during the opening inspection, which will destroy the scene, and the evidence required for accident analysis is not easy to retain; 3. Due to the relatively large detection range However, digital ray detection has poor targeting and a large detection workload, which is prone to missed detection and false detection; 4. Component analysis takes a certain amount of time
Due to the existence of these problems, the existing methods cannot accurately and quickly determine the location and cause of GIS discharge accidents

Embodiment Construction

[0008] The invention is further described below in conjunction with specific embodiments:

[0009] The present invention utilizes color-changing paint and digital rays to quickly determine the method for the cause of GIS equipment discharge accidents. The location of the discharge accident can be determined by the color change of the color-changing paint, and then the location of the discharge accident is photographed by digital ray detection equipment to obtain the cause of the accident at the location of the discharge accident

[0010] In the present invention, the color-changing paint adopts general color-changing paint, and the digital ray detection equipment is an X-ray machine.

[0011] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technic...

Abstract

The invention discloses a method for rapidly determining causes of the discharge accident of GIS by use of chameleon paint and digital radiography. The GIS is included, the GIS is coated with the chameleon paint, when the discharge accident happens to the GIS, firstly, the discharge accident location can be determined according to color change of the chameleon paint, and then, digital radiography detection equipment is used for shooting the discharge accident location to acquire causes of the accident in the discharge accident location. Compared with the prior art, the method has the characteristics of being accurate in positioning, rapid in analysis and the like, and is particularly suitable for detecting the discharge accident of the GIS.

Description

technical field [0001] The invention relates to a method for quickly determining the cause of a GIS equipment discharge accident by using color-changing paint and digital rays, and belongs to the technical field of GIS equipment accident detection. Background technique [0002] Power GIS equipment is the abbreviation of combined electrical appliances composed of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, busbars, connectors and outlet terminals. SF filled with a certain pressure 6 Insulating gas, so it is also called SF 6 Fully enclosed combined electrical appliances. Compared with conventional substations (AIS), GIS has the advantages of compact structure, convenient installation, and no influence of atmospheric environmental factors such as pollution, rain, and salt fog. [0003] For GIS discharge accidents, the traditional analysis steps are: 1. Analyze the protection action; 2. Determine the accident compartment; 3. SF 6 4...
