【衛生間(jian)電器接地(di)(di)】插座為什么要(yao)接地(di)(di)線 怎(zen)樣(yang)判斷插座接地(di)(di)線了
插座為什么要接地線:
作用1、地線起保護作用
電(dian)器(qi)設備的(de)(de)外(wai)殼通過(guo)插(cha)頭與(yu)(yu)地(di)(di)線(xian)相(xiang)連(lian)。插(cha)座接地(di)(di)線(xian)一旦漏電(dian),電(dian)器(qi)設備的(de)(de)外(wai)殼就會(hui)帶電(dian),但由(you)于地(di)(di)線(xian)的(de)(de)作用(yong),保證(zheng)電(dian)器(qi)外(wai)殼與(yu)(yu)地(di)(di)線(xian)等電(dian)位,即對地(di)(di)電(dian)壓等于0,這樣就保證(zheng)了電(dian)器(qi)使用(yong)者的(de)(de)人(ren)身安全(quan)。
作用2、防漏電
帶有接地線的 孔插座可以將洗衣機,電(dian)(dian)(dian)冰箱的(de)外(wai)殼接(jie)(jie)(jie)地(di),在漏(lou)電(dian)(dian)(dian)的(de)情(qing)況下,保(bao)護人(ren)不(bu)觸電(dian)(dian)(dian)。當用電(dian)(dian)(dian)器漏(lou)電(dian)(dian)(dian)時,電(dian)(dian)(dian)流直(zhi)接(jie)(jie)(jie)通過地(di)線(xian)進(jin)入大(da)地(di)。防止(zhi)人(ren)觸摸用電(dian)(dian)(dian)器是(shi)(shi)(shi)被(bei)電(dian)(dian)(dian)擊。地(di)線(xian)是(shi)(shi)(shi)直(zhi)接(jie)(jie)(jie)與大(da)地(di)相(xiang)通的(de),它(ta)與大(da)地(di)之間的(de)電(dian)(dian)(dian)阻(zu)遠遠小于人(ren)身電(dian)(dian)(dian)阻(zu),所以地(di)線(xian)是(shi)(shi)(shi)相(xiang)當重要(yao)的(de)。你們家里的(de)電(dian)(dian)(dian)腦的(de)電(dian)(dian)(dian)源插座有沒有連接(jie)(jie)(jie)著地(di)線(xian)?比較精密(mi)的(de)電(dian)(dian)(dian)氣設備還可(ke)以釋放靜電(dian)(dian)(dian),保(bao)護電(dian)(dian)(dian)氣設備及時導走電(dian)(dian)(dian)器上(shang)產生(sheng)的(de)靜電(dian)(dian)(dian)或漏(lou)電(dian)(dian)(dian)。
怎(zen)樣判(pan)斷(duan)插座接(jie)地線了(le):
首先把(ba)屋(wu)(wu)里總電源斷掉(diao),找(zhao)一根長線(xian),一個手電燈泡(pao)一節大(da)電池,長線(xian)一頭插(cha)到(dao)其(qi)它插(cha)座(zuo)(可(ke)以是(shi)本(ben)屋(wu)(wu)也可(ke)以是(shi)其(qi)它屋(wu)(wu)的插(cha)座(zuo))地線(xian)那眼里,一頭接電池再接燈泡(pao),燈泡(pao)甩出來的另一頭插(cha)要測的插(cha)座(zuo)地線(xian)那眼里,利用屋(wu)(wu)里地線(xian)做(zuo)個回(hui)路(lu),燈泡(pao)著就沒問題,把(ba)所有的插(cha)座(zuo)地線(xian)眼都試試,證明屋(wu)(wu)里所有地線(xian)都沒問題!
小編總結:插座里的地線經專線通往大地,插頭上較長的那只腳與用電器的金屬外殼連接。當用電器出現漏電故障時或用電器使用時使外殼帶上正常的感應電時,這些電會通過地線被導入大地,以避免人員觸電,起到保護人身安全的作用。據調查統計,所有的因電熱水器、冰箱等用電(dian)器漏電(dian)造成的觸(chu)電(dian)死亡事故,用電(dian)器全(quan)部未(wei)接地線(xian)或地線(xian)接地不良。
