Abstract

The invention relates to a substation power transformer overheating fault monitoring system based on a thermal infrared imager. A data acquisition module receives data output by the thermal infrared imager. The data acquisition module acquires infrared images obtained by the thermal infrared imager into a computer monitoring software system, and the infrared images are processed by an infrared image processing module. The data acquisition module transmits obtained temperature data information to a temperature measurement and display module. After format conversion is conducted on the infrared images acquired by the infrared image processing module, the infrared images are transmitted to an image displayer. The output end of the temperature measurement and display module is connected with a temperature displaying and alarming device. According to the substation power transformer overheating fault monitoring system based on the thermal infrared imager, online timed full-automatic temperature monitoring and intelligent fault alarming can be conducted on a transformer through the online monitoring software system, remote temperature monitoring of the unattended substation power transformer is achieved, manpower and material resources are saved greatly, and traditional planned maintenance of power equipment is converted into cognition-based maintenance of power equipment.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a substation power transformer overheating fault monitoring system based on an infrared thermal imager. Background technique [0002] The online monitoring system for overheating faults of substation power transformers based on infrared thermal imager realizes the functions of on-line monitoring and automatic alarm for overheating faults of substation power transformers. Substation power transformer is an important equipment for power system operation. Due to long-term operation and environmental factors, various failures occur, which affect the operation of the entire power supply system and cause economic losses. With the rapid development of the modern power industry, the power supply system has higher and higher requirements for the distribution quality of electric energy. Any problem in the production, transmission and distribution of electric energy in the power sys...
