韓國Jokwang ILI朝光JSV-HT52 20A折扣清倉! 切斷電流的觸頭固然重要，但真正重要的是如何切斷電弧。因為電弧引起的高溫和燒蝕，是決定觸頭壽命的關(guān)鍵。2、直流電流不容易切斷，是指直流電弧不容易切斷。原因在于直流電弧沒有“過零”的狀態(tài)，所以盡管有滅弧罩的冷卻，也不容易切斷電弧。 電流互感器的基本作用是信 變換和隔離。正因為有隔離，因此，二次回路在接地前是浮地系統(tǒng)，也就是說，其電位與地電位沒有固定關(guān)系。單點接地相當(dāng)于給接地點一個參考電位，并不形成回路，不會短路，也不會影響測量。如果多點接地，且接地前，這些接地點之間有電位差，那么，接地后就會形成回路，相當(dāng)于短路，將造成測量結(jié)果錯誤。
3.右手定則當(dāng)閉合電路中的一部分導(dǎo)線做切割磁感線運動時，感應(yīng)電流的方向可用右手定則來判斷：伸開右手，使大與其余四指垂直，并且都跟手掌在一個平面內(nèi)，讓磁感線垂直進入手心，大向?qū)w運動方向，這時四指所指的方向就是感應(yīng)電流的方向，如下圖所示。

十位代表常開觸點的數(shù)量，個位表示常閉觸點的數(shù)量。一般三相器一共有8個點，三路輸入，三路輸出，還有是控制點兩個。輸出和輸入是對應(yīng)的，很容易能看出來。如果要加自鎖的話，則還需要從輸出點的一個端子將線接到控制點上面。
