描述

(1)油枕:其容量约为互感器油量的8-10%。作用是:容纳互感器因温度的变化使互感器油体积变化,限制互感器油与空气的接触,减少油受潮和氧化程度。油枕上安装吸湿器,防止空气进入互感器。

(2)吸湿器和净油器:吸湿器又称呼吸器,内部充有吸附剂,为硅胶式活性氧化铝,其中常放入一部分变色硅胶,当由兰变红时,表明吸附剂已受潮,必须干燥或更换。净油器又称过滤器,净油缸内充满吸附剂,为硅胶式活性氧化铝等,当油经过净油器与吸附剂接触,其中的水份、酸和氧化物被吸收,使油清洁,延长油的使用年限。

(3)防爆管(安全气道):防爆管安装在互感器箱盖上,作为互感器内部发生故障时,防止油箱内产生高压力的释放保护。现代大型互感器已采用压力释放阀代替安全气道。当互感器内部发生故障压力升高,压力释放阀动作并接通触头报警或跳闸。此外,互感器还具有瓦斯保护,温度计、油表等安全保护装置。
