Based on the principle of infrared radiation,a non-contacted sensor which can be used on-line to monitor the temperature in high voltage device is developed. Some factors such as detection range, outside thermal source, surface condition and thermopile抯 temperature, which will affect the reliability and precision of the sensor are studied. Some measures which can improve the sensor抯 performance are given. The measures include deciding suitable detection range, eliminating the disturbance of the outside thermal source by a special shell and eliminating the effect of the varied surface by painting special paint. There are some innovation for the non-contacted sensor抯 reliability and precision which are based on the principle of infrared radiation in this research. It is considered that the present work has practical significance for improving the reliability of high voltage device and power system as well.
