一、漏電開關的使用壽命以什么為限制

關(guan)于漏電(dian)開(kai)關(guan)的(de)使(shi)用(yong)(yong)(yong)壽(shou)命，有很(hen)多人(ren)持(chi)不同的(de)看法。有些(xie)人(ren)認(ren)為(wei)(wei)漏電(dian)開(kai)關(guan)的(de)使(shi)用(yong)(yong)(yong)壽(shou)命應(ying)該是(shi)以使(shi)用(yong)(yong)(yong)次數(shu)為(wei)(wei)限制(zhi)，也(ye)就是(shi)經過多少次使(shi)用(yong)(yong)(yong)后(hou)需(xu)要更(geng)換(huan)；而(er)有些(xie)人(ren)則認(ren)為(wei)(wei)漏電(dian)開(kai)關(guan)的(de)使(shi)用(yong)(yong)(yong)壽(shou)命應(ying)該是(shi)以年限為(wei)(wei)限制(zhi)，也(ye)就是(shi)經過多少年后(hou)需(xu)要更(geng)換(huan)。

實際上，漏電(dian)開(kai)關的(de)使用壽命應(ying)該是以時(shi)間(jian)為限制。由于漏電(dian)開(kai)關內部的(de)電(dian)氣元(yuan)件和(he)機械部件都會(hui)隨著時(shi)間(jian)的(de)延(yan)長而發生老(lao)化、磨損等(deng)情況(kuang)，因(yin)此漏電(dian)開(kai)關需要在(zai)一定的(de)時(shi)間(jian)周期內更換，以保障其(qi)正常使用和(he)保護作用。

二、漏電開關的壽命是多少年

一般來(lai)說，漏電開關的使(shi)(shi)用(yong)(yong)壽命應該在5年左右(you)。當然(ran)，具(ju)體(ti)的使(shi)(shi)用(yong)(yong)壽命還會(hui)受(shou)到漏電開關的品(pin)牌、質量、環境條件等(deng)多種(zhong)因素的影響，因此在實際使(shi)(shi)用(yong)(yong)中還需要根(gen)據(ju)具(ju)體(ti)情況(kuang)進行(xing)判(pan)斷(duan)。

三、漏電開關如何保養和維護

1、定(ding)期(qi)清掃灰塵，保持漏(lou)電開關外殼及其上(shang)部件(jian)、連(lian)接(jie)端子的(de)清潔(jie)、完(wan)好和牢(lao)固連(lian)接(jie)；漏(lou)電開關外殼膠木件(jian)的(de)溫度(du)(du)不得超過65攝氏(shi)度(du)(du)，外殼金(jin)屬件(jian)溫度(du)(du)不得超過55攝氏(shi)度(du)(du)。同(tong)時，還(huan)要保持漏(lou)電開關操作手柄動作靈(ling)活、可(ke)靠。

2、漏(lou)電開關安裝(zhuang)場(chang)所應(ying)通風(feng)、干燥，有預防雨(yu)淋、灰塵和(he)有害氣體(ti)侵(qin)蝕的措施。應(ying)盡量(liang)遠離其他鐵磁(ci)體(ti)和(he)電流(liu)很大的載流(liu)導體(ti)，避免磁(ci)場(chang)干擾。漏(lou)電開關安裝(zhuang)場(chang)所的環(huan)境溫度應(ying)在－5～40攝氏度之間。

3、至少應每月檢驗一次家(jia)用漏電開關(guan)動作的(de)可靠性。具(ju)體(ti)方法是：按(an)一下試驗按(an)鈕，如漏電開關(guan)正(zheng)確斷開，說明正(zheng)常；反之，則說明漏電開關(guan)存在故障(zhang)，應請有經驗、有資質(zhi)的(de)電工進行檢查更換。高溫多雨的(de)夏秋季(ji)節(jie)和農(nong)忙季(ji)節(jie)應增加(jia)試驗次數(shu)。

4、漏電(dian)(dian)(dian)(dian)(dian)開關(guan)使用一(yi)年后，應請專(zhuan)業電(dian)(dian)(dian)(dian)(dian)工對其進行檢(jian)(jian)(jian)修(xiu)，檢(jian)(jian)(jian)修(xiu)內容有：測試保(bao)護(hu)器漏電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)作值是(shi)(shi)否(fou)符合規定；檢(jian)(jian)(jian)查絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻，漏電(dian)(dian)(dian)(dian)(dian)開關(guan)一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)路各(ge)部絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻應在1．5兆(zhao)歐(ou)以(yi)上；測量(liang)家庭室內線路漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，消除各(ge)種漏電(dian)(dian)(dian)(dian)(dian)隱患；檢(jian)(jian)(jian)查漏電(dian)(dian)(dian)(dian)(dian)開關(guan)接(jie)(jie)(jie)線及保(bao)護(hu)接(jie)(jie)(jie)地(di)裝置是(shi)(shi)否(fou)松動(dong)(dong)和接(jie)(jie)(jie)觸不(bu)良等。檢(jian)(jian)(jian)修(xiu)完畢后，應在現場進行一(yi)次(ci)實(shi)際模擬試驗(yan)。方法是(shi)(shi)，用一(yi)支6千歐(ou)10瓦線繞電(dian)(dian)(dian)(dian)(dian)阻，兩(liang)端(duan)各(ge)接(jie)(jie)(jie)一(yi)絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)線，一(yi)頭插(cha)入(ru)插(cha)座的相(xiang)線孔(kong)，另一(yi)頭與(yu)大(da)地(di)連接(jie)(jie)(jie)，接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻與(yu)變壓器中性點接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻相(xiang)同。這時有一(yi)約40毫(hao)安的漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，如果(guo)漏電(dian)(dian)(dian)(dian)(dian)開關(guan)立即跳閘(zha)，則(ze)可(ke)以(yi)放心(xin)使用。

5、漏電(dian)(dian)開關動作后(hou)不(bu)強行送(song)電(dian)(dian)。保護器(qi)動作后(hou)，若經(jing)檢(jian)查(cha)未發現事故(gu)點，允許試送(song)電(dian)(dian)一(yi)次，如果再次動作，應查(cha)明原因，并采取相應措(cuo)施處理后(hou)方能恢復(fu)通電(dian)(dian)。尤其是漏電(dian)(dian)開關在檢(jian)測到漏電(dian)(dian)、短路現象后(hou)跳閘時，一(yi)定要查(cha)清和消(xiao)除存在的(de)電(dian)(dian)氣(qi)隱患，千萬(wan)不(bu)要隨意讓其退出(chu)運(yun)行，否則就會引發惡性事故(gu)。
