本文描述了环境温度变化对压缩气体电容器电容量的影响规律,提出了电容器的温度响应概念。对BF350—50T电容器进行了温度响应的试验,通过试验和本文所阐明的规律计算了对于BF350—50T电容器在一次四小时试验过程中环境气温均匀地变化2℃的严重情况下,其电容量变化也还是小于4×10~(-6)。若试验过程缩短为二小时,则电容量变化带来的误差小于1×10~(-6)。
This paper describes the influence of ambient temperature on the capacitance of compressed gas capacitor and puts forward the concept of temperature response of capacitor. The temperature response of BF350-50T capacitor was tested. The capacitance of BF350-50T capacitor was calculated by the experiment and the rule set forth in this paper in the severe case of BF350-50T capacitor whose temperature was changed by 2 ℃ in a four-hour test. Also less than 4 × 10 -6. If the test process is shortened to two hours, the error caused by the capacitance change is less than 1 × 10 -6.
