Abstract

The invention discloses an electric equipment fault analysis and diagnosis method and a system based on infrared imaging temperature measurement. According to the method, an online infrared imaging temperature measurer is employed to carry out temperature measurement and video shooting for a detection part of electric equipment to acquire temperature measurement data and video data which are together transmitted to a monitoring computer in real time, fault analysis and diagnosis on the electric equipment are realized through line temperature analysis, equivalent temperature analysis, gradient temperature field distribution analysis and largest continuous load overheat spot temperature analysis on the monitoring computer. Through the method, all-day-round monitoring can be realized, a problem of a fault of the electric equipment can not be timely discovered through hand-operated temperature measurement is effectively solved, the present basic picture analysis situation is effectively expanded, and temperature measurement analysis and present equipment state timeliness are improved.

Description

technical field [0001] The invention relates to a method and system for analyzing and diagnosing electric equipment faults, in particular to a method and system for analyzing and diagnosing electric equipment faults based on infrared imaging temperature measurement. Background technique [0002] The existing infrared temperature measurement of electric power equipment mainly has the following methods: 1. Using a handheld thermometer; 2. Using an intelligent robot; 3. On-line monitoring. Hand-held thermometers are seriously affected by the professional quality of photographers and environmental conditions, and cannot monitor the operating status of power equipment in real time. The temperature measurement data cannot truly reflect the status of the equipment under specific environmental conditions; the temperature measurement of intelligent robots is not only affected by the environmental climate, but also At the same time, there are also problems in accurately locating the d...
