Online accurate temperature measurement method and online accurate temperature measurement system for electric power equipment

Abstract

The invention discloses an online accurate temperature measurement method and an online accurate temperature measurement system for electric power equipment. Online infrared imaging temperature measurement instrument is employed to measure temperature of the electric power equipment, temperature, wind speed and humidity sensors are mounted around the electric power equipment, and normalization processing on environment conditions is carried out; a current heating equipment, temperature measured under the condition of low temperature is converted to temperature under the 20 DEG C condition, and heat radiation influence caused by wind speed is further converted. According to the method and the system, under the condition of the practical present environment climate, normalization correction on the temperature measurement data of the electric power equipment is carried out, influence of an environment climate factor is converted, and accurate measurement on temperature of crucial parts of the electric power equipment is realized.

Description

technical field [0001] The invention relates to a temperature measuring method and system for electric power equipment, in particular to an online accurate temperature measuring method and a temperature measuring system for electric power equipment. 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 At the same time, there are also problems in accurately locating the detection parts of the equip...

AI Technical Summary

Problems solved by technology

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 At the same time, there are also problems in accurately locating the detection parts of the equipment; at present, online infrared temperature measurement and monitoring is being carried out at home and abroad, but the temperature measurement method is rough, and it cannot achieve the purpose of accurate temperature measurement of key parts of power equipment

Moreover, these temperature measurement methods are mostly limited to heat map capture, post-event analysis, or limited to a fixed number of temperature measurement objects on the same screen.
