Abstract

The invention discloses a method for diagnosing equipment overheating defects by utilizing infrared spectrum analysis. The method comprises the following steps: establishing a standard spectrum library and a typical abnormal infrared spectrum library; acquiring an infrared chart of equipment on site and identifying and matching standing book information of the equipment; calculating related temperature indexes of the spectrum, and automatically extracting the most similar case spectrum; fully contrasting the standard spectrum, the typical abnormal spectrum and the most similar case spectrum, and analyzing and judging whether the equipment is overheated; judging and ranking the equipment state and defect degree, analyzing the risk and giving processing decision suggestions; and transmitting the state data and decision suggestions to a production management system. According to the method for diagnosing equipment overheating defects by utilizing infrared spectrum analysis, centralized management and information sharing of the spectrums are conveniently realized, the accuracy and reliability of spectrum analysis and diagnosis are improved, ad the method provides decision suggestions for field defect processing, is in interactive cooperation with the production management system and has a positive effect of thoroughly promoting equipment state maintenance.

Description

technical field [0001] The invention belongs to the field of live detection and diagnosis of electrical equipment, and in particular relates to a method for analyzing and diagnosing whether an overheating defect occurs in an electrical equipment during operation by using an infrared spectrum. Background technique [0002] Electrical equipment is often damaged due to overheating defects, and sometimes even lead to serious power grid accidents. Therefore, how to detect equipment overheating defects as early as possible and in time to ensure the health of equipment and the safety of power grid operation has become a concern for power companies. Infrared thermal imaging technology can quickly and real-time obtain equipment surface and internal temperature information, and does not need to directly contact live equipment in operation, so it can conveniently and accurately analyze and diagnose most equipment overheating defects, and can play an important role in the actual field. ...
