with the substation construction and retrofit, gradually achieve the unattended substation operation, long-term high temperature operation is the main cause of equipment wear and tear, fault, in view of the continuously monitor equipment operation temperature, helps to discover the hidden trouble of equipment operation, master the equipment running status, improve the operating life of equipment. Temperature measuring technology as the main technical means, through continuous improvement to upgrade, there are so many ways to achieve, but the lack of standards and specifications. Through the comparison and analysis of the principle of the existing equipment temperature monitoring technology, concludes the key points of equipment temperature measurement technology, discusses the development trend of substation equipment temperature measurement technology, formation of substation equipment should have the characteristics of temperature monitoring technology. In substation operations management and equipment maintenance as the goal, combined with the Internet of things, the sensing technology, the realization of intelligent substation temperature measuring technology application.
