Device and method for detecting operation state of ultra-high-voltage transformer in transformer substation based on 3D infrared panoramic image

Abstract

The invention discloses a device and method for detecting an operation state of an ultra-high-voltage transformer in a transformer substation based on a 3D infrared panoramic image, and aims to solve the problem that only parts of infrared thermal images of the transformer can be simultaneously obtained and a global temperature distribution thermal image of the transformer cannot be obtained when the operation state of the ultra-high-voltage transformer is detected traditionally. The device comprises a circular orbit paved around the transformer; the central axis of the transformer passes through the circle centre of the circular orbit; an intelligent controllable trolley is arranged on the circular orbit; a camera is arranged on the intelligent controllable trolley through a bracket; the camera comprises an infrared camera and a visible light camera; a panoramic fused image is formed by utilizing an image fusion technology; 3D left and right eye images are generated; recoding is carried out; and finally, the image is output onto a touch monitoring screen. According to the invention, the real-time operation state of the transformer can be reflected vividly; the operation state of the transformer can be observed without a dead angle from different angles; and operation faults can be judged in time.

Description

technical field [0001] The invention relates to a device for detecting the operating state of a transformer in an ultra-high voltage substation based on a 3D infrared panoramic image, and belongs to the technical field of detecting the operating state of the ultra-high voltage substation equipment. Background technique [0002] The safe operation of UHV substation transformers directly affects the safety and reliability of the power grid, so the status monitoring of UHV substation transformers is very necessary. Many faults of transformers are manifested by abnormal temperature, so the application of infrared thermal imager can detect transformer faults. Due to the huge size of the UHV transformer, the traditional infrared thermal image can only obtain the infrared heat map of the transformer part at the same time, and cannot know the overall temperature distribution heat map of the transformer. In addition, the infrared heat map information is single, which can only reflect...

Problems solved by technology

[0006] The purpose of the present invention is to provide a UHV substation transformer operating state detection device based on a 3D infrared panoramic image, which mainly solves the problem that the traditional infrared thermal image can only obtain the infrared thermal image of the transformer part at the same time when detecting the operating state of the UHV transformer, and cannot know The problem of the heat map of the global temperature distribution of the transformer, so the operating status of the transformer cannot be fully observed, and the operating fault cannot be judged early
