一、工作原理Principleofoperation
BG外油式波纹储油柜采用先进的超柔性不锈钢波纹补偿器作为容积补偿元件和隔离密封元件,在彻底隔绝空气及湿气的条件下,实现对变压器绝缘油的体积补偿。如图1所示,波纹补偿器是一个内腔与大气相通的气囊,放置于绝缘油中,储油腔通过下部连接口与变压器油箱相通。波纹补偿器内腔通过呼吸口与外界大气相通。当绝缘油随温度变化产生体积膨胀或收缩时,促使波纹补偿器伸缩,从而改变柜内油腔大小,实现对绝缘油的体积变化补偿。储油柜各部件的名称及作用参见图1所示。

4.注油程序NormalProcesofOilInjection
注油→定油位→排气→调整油位
Oil injection → Positioning oil level → Gas discharge →Adjustingoillevel
①注油Oilinjection
打开呼吸口及排气口阀门,从变压器本体或注油口向储油柜内注油
Openthebreathventandtheexhaustvent,injectedthroughtransformeroroilinjectionvent
②定油位Positioningoillevel
注油后油位指示不断升高,当指示窗油位刻度达到与油温对应的数值时,关闭呼吸口。继续注油,直至储油柜内空气排净。

※注:1.图中温度为现场实际油温(平均);
2.根据产品使用地区的最低环境温度选择对应的曲线a、b、c、d(之一),以横坐标油温对应纵坐标油位;
3.储油柜油位计是通过与波纹补偿器活动端面相连的金属带做传导,波纹补偿器伸缩时产生窗口刻度的变化,显示0~10的油位,0为最低油位,10为最高油位,见本页上图。

③排气Gasdischarge④调整油位Adjustingoillevel
首次注油后静置1~2小时,然后再次排净打开呼吸口检查油位,并将油位调整到与油温储油柜内气体对应

※注油完毕后,将储油柜置于工作状态:呼吸口常开,排气口、注油口可靠密封。

5.注意事项Attentions
●储油柜吊装落位时,注意防止碰撞筒体及油位视窗;
●注油过程中,应将储油柜油腔内气体排净,以免形成假油位。排净气体的标准是:排气口连续稳定
出油。排净气体后,排气口阀门及注油口阀门关闭,同时用盖板可靠密封;
注:储油柜内滞留的气体因受热膨胀系数远大于绝缘油,将严重减少补偿空间。
●储油柜的工作状态应是:呼吸口阀门常开,排气口、注油口阀门关闭。
