Transformer charged detection system and method based on infrared temperature measurement

Abstract

The invention discloses a transformer charged detection system and a method based on infrared temperature measurement. A controller controls the shutter time of an infrared planar array detector and the focusing action of a lens; the infrared planar array detector acquires infrared data of the transformer; the controller receives the signals acquired by the infrared planar array detector; the signals are subjected to digital-to-analog conversion to obtain digital voltage signals; the digital voltage signals are filtered and the data are cached to a memory; an upper computer reads the data after filtering; a fault identification algorithm is used for carrying out early warning on fault possibly happening in the transformer, and the possible fault is imaged on an image for marking. The uncooled infrared focal plane array detector based on a microbolometer is used for reading voltage signals generated by the circuit, the working condition of the transformer is judged in real time through the fault detection algorithm, early warning is carried out before possible fault, and charged detection is realized.

Description

technical field [0001] The invention relates to a live detection system and method based on an infrared temperature measuring transformer. Background technique [0002] Transformer is the core equipment of my country's power system. It occupies an extremely important position in the operation and maintenance of the power system. Once a fault occurs, it is easy to cause the collapse of the power grid, affect production and life, and cause huge economic losses. Therefore, as long as it can be timely Finding the fault of the transformer and successfully repairing it can greatly improve the stability of the power system operation, while ordinary preventive maintenance and regular maintenance require power outage maintenance, which will reduce the reliability and economy of power supply, so It is necessary to use a method that can detect electricity under the continuous power situation. [0003] The commonly used infrared temperature measurement method now is to use a handheld the...
