根據(jù)某地客戶反饋一臺彎箍機就出現(xiàn)了這樣的問題?？蛻舴从?，機器一旦通電啟動，觸摸控制臺就會觸電。這種電擊本質(zhì)上是由相對短路引起的。電機崩潰后，發(fā)現(xiàn)電機靠近裝置表面一側(cè)的軸承損壞，固定彈珠的花籃碎成幾塊，然后這些碎塊刮去了定子繞組的絕緣漆，導致漏電。觀察后發(fā)現(xiàn)，轉(zhuǎn)軸上的鍵槽也嚴重磨損。然后看輸送伺服的減速機，發(fā)現(xiàn)30度滾轉(zhuǎn)角的減速機沒有輸出。判斷是減速機故障導致?lián)p壞，從而引起觸電。鑒于這些問題，可能有必要安裝漏電保護器，以避免彎箍機的電氣控制系統(tǒng)出現(xiàn)問題。還有，電擊人體的原因是什么？這個問題對于電氣操作人員來說其實是一個非常重要的問題。電擊的本質(zhì)是人體有電流流過。當電流達到10mA時，人體會有觸電的感覺。

現(xiàn)場觸電一般是人站在地上，觸摸相電壓或觸摸帶電體引起的。當然，有時當人們需要觸摸帶電體時，此時好用右手背去觸摸。用右手是因為人的心臟一般是左的，可以避免電流通過心臟。用手背觸摸更方便人體快速脫離帶電體。還有一個小問題。當人們用手觸摸帶電體時，他們會觸電。電流從手指流到腳上，然后流到地上。但是為什么只有手指感覺到嫩，而身體的其他部位卻感覺不到呢？原因是手指較細，單位面積電流較大，所以手指有觸電的感覺，而身體與手指相關的截面積較大，單位面積電流較小，所以身體沒有觸電的感覺。
