摘要
充油互感器全密封逆止呼吸器适应于35~220kV电压等级的油浸式电压、电流互感器压力释放,也适用于50kVA 以下变压器。当变压器油体积发生胀缩时产生的气体通过本呼吸器进行呼吸,自动释放压力(气体)并延迟自动关闭,保证内部有一定的微正压。防止外部潮湿污秽气体进入,避免了内部结露进水、变压器油受潮。减缓了变压器油的老化。
The totally-sealed irreversible respirator of oil-filled transformer is usedfor releasing pressure in the oil-immersed voltage or current transformers ofvoltage grade from 35kV to 220kV and for the transformers of power gradebelow 50kVA.when the volume of transformer oil expanded or contracted thegas produced respires by the respirator and the gas sressure will be automati cally released.The respirator can be closed with delay.There is a specifiedpositive micro-pressure in it.it is able to prevent external moist filthy gasentering and to avoid dew and water existence inside,therefore to slow downthe aging of the transfomer oil.
