Description
technical field [0001] The present application relates to the technical field of substation temperature measurement, in particular to a substation infrared temperature measurement device and method based on temperature dynamic calibration. Background technique [0002] With the development of infrared temperature measurement technology, power grid enterprises use a large number of infrared temperature measurement equipment in substations to monitor the temperature of primary equipment in operation. Through temperature analysis, the operation of operating equipment in substations is analyzed to ensure the safe operation of the power grid. [0003] Due to the influence of infrared temperature measurement technology hand environment, personnel use method, equipment parameter setting and other factors, in the daily operation monitoring of substations, false alarms of defects often occur due to inaccurate infrared temperature measurement data. Therefore, it is necessary to config...
