概要

論文の詳細を見る
Based on the principle of infrared radiation, a non-contacted sensor that can be used on-line to monitor the temperature in switchgear is developed Some factors such as temperature detection range, ambient thermal source, object's surface condition and thermopile detector's temperature, which will affect the reliability and precision of the sensor are studied Some measurements that can improve the sensor's performance are given The measurements include deciding suitable temperature detection range, eliminating the disturbance of the ambient thermal source by a special shell, eliminating the effect of the varied surface hence different radiation rate by painting special dope, especially eliminating the influence of thermopile detector's temperature which vanes following the ambient temperature by using compensation technique through software.
