上海喆和定制銷售西門子電流互感器。按絕緣介質分類1、干式電流互感器[4]：由普通絕緣材料經(jīng)浸漆處理作為絕緣。2、澆注式電流互感器：用環(huán)氧樹脂或其他樹脂混合材料澆注成型的電流互感器。3、油浸式電流互感器：由絕緣紙和絕緣油作為絕緣，一般為戶外型。4、氣體絕緣電流互感器：主絕緣由氣體構成。按安裝方式分類1、貫穿式電流互感器[5]：用來穿過屏板或墻壁的電流互感器。2、支柱式電流互感器：安裝在平面或支柱上，兼做一次電路導體支柱用的電流互感器。3、套管式電流互感器：沒有一次導體和一次絕緣，直接套裝在絕緣的套管上的一種電流互感器。4：母線式電流互感器：沒有一次導體但有一次絕緣，直接套裝在母線上使用的一種電流互感器。按原理分類1、電磁式電流互感器根據(jù)電磁感應原理實現(xiàn)電流變換的電流互感器。2、電子式電流互感器[6]例如（1）光學電流互感器是指采用光學器件作被測電流傳感器，光學器件由光學玻璃、全光纖等構成。（2）空心線圈電流互感器。又稱為Rogowski線圈式電流互感器。空心線圈往往由漆包線均勻繞制在環(huán)形骨架上制成，骨架采用塑料、陶瓷等非鐵磁材料，其相對磁導率與空氣的相對磁導率相同。上海優(yōu)惠特賣電流互感器交貨快上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

電流互感器1次側只有1到幾匝，導線截面積大，串入被測電路。2次側匝數(shù)多，導線細，與阻抗較小的儀表(電流表/功率表的電流線圈）構成閉路。電流互感器的運行情況相當于2次側短路的變壓器，忽略勵磁電流，安匝數(shù)相等I1N1=I2N2電流互感器一次繞組電流I1與二次繞組I2的電流比，叫實際電流比I1/I2=N2/N1=k。勵磁電流是誤差的主要根源。測量用電流互感器的精度等級0.2/0.5/1/3,1表示變比誤差不超過±1%，另外還有0.2S和0.5S級。2、保護用電流互感器保護用電流互感器分為：1.過負荷保護電流互感器，2.差動保護電流互感器，3.接地保護電流互感器（零序電流互感器）保護用電流互感器主要與繼電裝置配合，在線路發(fā)生短路過載等故障時，向繼電裝置提供信號切斷故障電路，以保護供電系統(tǒng)的安全。保護用電流互感器的工作條件與測量用電流保護用電流互感器互感器完全不同，保護用互感器只是在比正常電流大幾倍幾十倍的電流時才開始有效的工作。保護用互感器主要要求：1.絕緣可靠，2.足夠大的準確限值系數(shù)，3.足夠的熱穩(wěn)定性和動穩(wěn)定性。
