Description

technical field [0001] The invention relates to a temperature measuring sensor and a temperature measuring system, in particular to an infrared imaging temperature measuring sensor and a temperature measuring system. Background technique [0002] Temperature is an important parameter to characterize the operating state of electrical equipment. Actual operation experience and theoretical analysis show that all kinds of faults at busbars and cable joints are not a sudden process, because the local temperature of the equipment continues to rise, making the insulation gradually aging and the leakage current gradually increasing. The occurrence of breakdown is a process from quantitative change to qualitative change. Therefore, by continuously monitoring the temperature change of the equipment, it is possible to grasp its operating status, and carry out power outage maintenance in due course. Monitoring and evaluating the operating status of electrical equipment through real-ti...
