瞬間高壓會(huì)擊穿超過耐壓的電子器件，甚至超過器線圈本身的耐壓使線圈損壞。為了消除此影響，可以采取如下方法：1、在線圈兩端并聯(lián)電阻并聯(lián)電阻使線圈在突然斷電時(shí)仍有電流通路，這樣就降低了電流變化率，使自感電動(dòng)勢(shì)下降。

(：)這里需要注意的就是時(shí)間繼電器的觸點(diǎn)，帶有延時(shí)的觸點(diǎn)，是得電延時(shí)還是失電延時(shí)，一定要記牢才行，上學(xué)到的一個(gè)口訣，記住了也就好處理了。左凸右凹，延頭瞬尾；左凹右凸，瞬頭延尾；凹凸都有，延頭延尾；NONC看常態(tài)。 二次回路由電流互感器的二次線圈、儀表以及繼電器的電流線圈串聯(lián)組成。電流互感器大致可分為兩類，測量用電流互感器和保護(hù)用電流互感器。電流互感器的原理是依據(jù)電磁感應(yīng)原理，它的一次繞組經(jīng)常有線路的全部電流流過，電流互感器在工作時(shí)，它的2次回路始終是閉合的，因此測量儀表和保護(hù)回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。
