造成鐵心飽和磁化,嚴重乃至燒毀線圈;同時,磁路飽和磁化后,使誤差增大。電流互感器在正常工作時,二次側與測量儀表和繼電器等電流線圈串聯使用,測量儀表和繼電器等電流線圈阻抗很小,二次側近似于短路。CT二次電流的大小由一次電流決定,二次電生的磁勢,是平衡一次電流的磁勢的。若突然使其開路,則勵磁電動勢由數值很小的值驟變?yōu)楹艽蟮闹担F芯中的磁通呈現嚴重飽和的平頂波,因此二次側繞組將在磁通過零時感應出很高的尖頂波,其值可達到數千甚至上萬伏,危及工作人員的及儀表的絕緣性能。另外,二次側開路使二次側電壓達幾百伏,一旦觸及將造成觸電事故。因此,電流互感器二次側都備有短路開關,防止二次側開路。在使用中。用于測量儀表的電流互感器宜裝在發(fā)電機中性點側。接線電流互感器的接線按其所接負載的運行要求確定。常用的接線為單相、三相星形和不完全星形三種,分別如圖4a、圖4b和圖4c。電流互感器接線電流互感器接線額定變比和誤差:電流互感器的額定變比KN指電流互感器的額定電流比。即:KNI1N/I2N電流互感器原邊電流在一定范圍內變動時,一般規(guī)定為10~120%I1N,副邊電流應按比例變化,而且原、副邊電壓(或電流)應該同相位。但由于互感器存在內阻抗、勵磁電流和損耗等因素而使比值及相位出現誤差,分別稱為比差和角差。比差為經折算后的二次電流與一次電流量值大小之差對后者之比,即fI為電流互感器的比差。
