電流互感器用來(lái)測(cè)量交流大電流或進(jìn)行交流高電壓下電流的測(cè)量，它是根據(jù)變壓器的變流原理制成的，即式中稱電流變比，。為已知常數(shù)，根據(jù)測(cè)出的就可算出待測(cè)的。電流互感器副邊繞組的額定電流表規(guī)定為5A或1A。下圖為電流互感器的接線圖。 并建議10kV側(cè)電容器組分組容量確定為2000、3000、6000kvar。（2）對(duì)于普通負(fù)荷的公用變的0.4kV低壓補(bǔ)償，可按配變?nèi)萘康?0%～30%進(jìn)行補(bǔ)償。（3）當(dāng)三相電壓不平衡時(shí)（如單相負(fù)荷較多），需考慮一定容量的分相補(bǔ)償。（4）對(duì)于企業(yè)變壓器的0.4kV低壓補(bǔ)償，可按配變?nèi)萘康?0%～60%進(jìn)行補(bǔ)償。 一般以“m*”表示。除非說(shuō)明書中另有說(shuō)明，一般觸點(diǎn)負(fù)載小于1A的繼電器用6Vd.c.，0.1A測(cè)量電阻，觸點(diǎn)負(fù)載大于1A的繼電器用6Vd.c.，1A測(cè)量電阻。1.2.1避免同一繼電器既通斷大負(fù)載又通斷小負(fù)載：因?yàn)橥〝噍^大負(fù)載時(shí)易產(chǎn)生觸點(diǎn)飛濺物，它們會(huì)附著于通斷微小負(fù)載的觸點(diǎn)上，導(dǎo)致觸點(diǎn)故障，因此，請(qǐng)避免同一繼電器既通斷大負(fù)載和又通斷小負(fù)載。

主觸頭一般接到主回路上,至于先后順序到時(shí)沒(méi)有特別要求,輔助觸頭接到控制回路上,一般要選擇是常開(kāi)觸點(diǎn)還是常閉觸點(diǎn).這個(gè)選擇是根據(jù)控制回路的要求而定,一般一個(gè)交流器如果常開(kāi)常閉觸點(diǎn)不夠用,以施耐德為例,可以在上方加上一個(gè)機(jī)構(gòu).類似于常開(kāi)常閉觸點(diǎn)可供使用。

2、斷相保護(hù)器又稱電機(jī)斷相保護(hù)器或者電源源相保護(hù)器，一般多用在三相電機(jī)電路上，如果缺少一路電，電機(jī)扭力會(huì)變小，轉(zhuǎn)子轉(zhuǎn)速會(huì)下降，從而導(dǎo)致其它兩路電流增大，燒毀電機(jī)繞組起原理就是通過(guò)不同，對(duì)三相電進(jìn)行?。 1、電磁系統(tǒng)。電磁系統(tǒng)由線圈、“E”形靜鐵心和銜鐵心組成，靜鐵心頭部裝有短路環(huán)，用于防止交流電流過(guò)零時(shí)銜鐵的振動(dòng)。2、觸頭部分包括三對(duì)主觸頭和四對(duì)輔助觸頭。主觸頭由三組橋式動(dòng)觸頭和上下兩側(cè)三對(duì)靜觸頭組成，觸頭材料為銀基合金，容量較大，允許通過(guò)較大的電流，起接通和斷開(kāi)主電路的作用。
