互感器的鐵芯為環(huán)形和矩形鐵芯,二次繞組沿鐵芯圓周均勻分布,采用阻燃塑料做互感器的絕緣外殼。互感器的中間留有窗口,供一次母線穿過;
產(chǎn)品出線標記:一次進線端用P1標記,出線端用P2標記;P2流出時,二次電流由S1流出,經(jīng)過外部回路由S2流入,即為減極性;
該產(chǎn)品的特點:鐵芯由硅鋼片卷繞成形,沒有氣隙,磁性能高。二次繞組均勻繞制,漏磁很小,具有性能穩(wěn)定、重量輕、安裝方便等優(yōu)點。
工作條件:
1.安裝場所:戶內(nèi);
2.環(huán)境溫度:-5℃-40℃且日平均不超過30攝氏度;
3.環(huán)境濕度:空氣相對濕度不大于80%;
4.海拔高度:互感器安裝海拔高度不超過1000m;
5.額定電壓:0.66kV;
6.額定二次電流:5A,1A(需要另外定做);
7.額定一次電流:500A-1000A;
8.準確度:0.5級,0.2級(需要另外定做);
9.絕緣性能:一次繞組對二次繞組及地和二次繞組對地能承受工頻耐壓3kV歷時1min。
