一、漏電開關的使用壽命以什么為限制

關(guan)于漏(lou)電(dian)開(kai)關(guan)的(de)(de)使(shi)用(yong)(yong)壽命，有很多(duo)人(ren)持不(bu)同的(de)(de)看(kan)法。有些人(ren)認(ren)為(wei)漏(lou)電(dian)開(kai)關(guan)的(de)(de)使(shi)用(yong)(yong)壽命應(ying)該(gai)是(shi)以使(shi)用(yong)(yong)次數為(wei)限(xian)制，也就(jiu)是(shi)經過(guo)多(duo)少次使(shi)用(yong)(yong)后(hou)需(xu)要更換；而有些人(ren)則認(ren)為(wei)漏(lou)電(dian)開(kai)關(guan)的(de)(de)使(shi)用(yong)(yong)壽命應(ying)該(gai)是(shi)以年限(xian)為(wei)限(xian)制，也就(jiu)是(shi)經過(guo)多(duo)少年后(hou)需(xu)要更換。

實際上，漏(lou)電開(kai)(kai)關的(de)使用壽命應該是(shi)以時間(jian)為限制。由于漏(lou)電開(kai)(kai)關內部的(de)電氣元件(jian)和(he)機械(xie)部件(jian)都會(hui)隨(sui)著時間(jian)的(de)延長而發(fa)生老化、磨(mo)損等情況，因此漏(lou)電開(kai)(kai)關需要在一定的(de)時間(jian)周期內更換，以保(bao)障其正常使用和(he)保(bao)護作用。

二、漏電開關的壽命是多少年

一般(ban)來說，漏電開(kai)關(guan)的(de)使用(yong)壽命(ming)應(ying)該在5年左右。當然，具(ju)體(ti)的(de)使用(yong)壽命(ming)還會受到漏電開(kai)關(guan)的(de)品牌(pai)、質量、環境(jing)條件等多種因素的(de)影響，因此在實(shi)際使用(yong)中(zhong)還需要根據具(ju)體(ti)情況進行判斷。

三、漏電開關如何保養和維護

1、定期(qi)清掃灰塵，保持(chi)漏電開關(guan)外殼(ke)(ke)及(ji)其(qi)上(shang)部件、連(lian)接端(duan)子的(de)清潔、完好和牢固連(lian)接；漏電開關(guan)外殼(ke)(ke)膠木(mu)件的(de)溫(wen)度(du)不(bu)得超(chao)(chao)過65攝(she)(she)氏度(du)，外殼(ke)(ke)金屬件溫(wen)度(du)不(bu)得超(chao)(chao)過55攝(she)(she)氏度(du)。同時，還要保持(chi)漏電開關(guan)操作(zuo)手柄動作(zuo)靈活(huo)、可(ke)靠。

2、漏(lou)電(dian)開關(guan)安裝場所應通風、干燥(zao)，有預防雨淋、灰塵和(he)有害氣體侵(qin)蝕的措施。應盡量(liang)遠離(li)其(qi)他鐵磁體和(he)電(dian)流很(hen)大的載流導體，避(bi)免磁場干擾。漏(lou)電(dian)開關(guan)安裝場所的環(huan)境溫度應在－5～40攝氏度之間(jian)。

3、至少應(ying)每月檢(jian)驗一(yi)次(ci)家(jia)用漏電(dian)開(kai)關動作的(de)可靠(kao)性。具體方法(fa)是(shi)：按(an)一(yi)下試驗按(an)鈕，如漏電(dian)開(kai)關正確斷開(kai)，說明正常；反(fan)之(zhi)，則(ze)說明漏電(dian)開(kai)關存在故障，應(ying)請有經(jing)驗、有資質(zhi)的(de)電(dian)工進(jin)行檢(jian)查更換。高溫多(duo)雨的(de)夏(xia)秋季(ji)節和農忙季(ji)節應(ying)增加試驗次(ci)數。

4、漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關使(shi)用(yong)一(yi)(yi)(yi)年后(hou)，應(ying)(ying)請專業(ye)電(dian)(dian)(dian)(dian)(dian)(dian)工對(dui)其進(jin)行檢(jian)修(xiu)，檢(jian)修(xiu)內容有(you)：測試保護器(qi)漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)動作值是(shi)否符合規定；檢(jian)查絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關一(yi)(yi)(yi)次電(dian)(dian)(dian)(dian)(dian)(dian)路各部(bu)絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)應(ying)(ying)在1．5兆(zhao)歐以上；測量家庭室內線路漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流，消除各種漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)隱患(huan)；檢(jian)查漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關接線及保護接地裝置是(shi)否松動和接觸不良等。檢(jian)修(xiu)完畢后(hou)，應(ying)(ying)在現場進(jin)行一(yi)(yi)(yi)次實際(ji)模擬(ni)試驗(yan)。方法是(shi)，用(yong)一(yi)(yi)(yi)支6千歐10瓦(wa)線繞電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，兩(liang)端各接一(yi)(yi)(yi)絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)線，一(yi)(yi)(yi)頭插入(ru)插座的相(xiang)線孔，另一(yi)(yi)(yi)頭與大地連接，接地電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)與變壓器(qi)中性(xing)點接地電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)相(xiang)同。這時有(you)一(yi)(yi)(yi)約(yue)40毫(hao)安的漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流，如果漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關立即(ji)跳閘，則可以放心使(shi)用(yong)。

5、漏(lou)電開(kai)關動(dong)作后(hou)不(bu)強行送電。保護器(qi)動(dong)作后(hou)，若經(jing)檢查未發現事故(gu)點，允許試送電一(yi)次，如果再次動(dong)作，應查明(ming)原因，并(bing)采取相應措施處(chu)理(li)后(hou)方(fang)能恢復通電。尤其(qi)是漏(lou)電開(kai)關在(zai)檢測(ce)到漏(lou)電、短(duan)路現象后(hou)跳閘(zha)時，一(yi)定(ding)要查清和(he)消除存在(zai)的電氣隱患，千萬不(bu)要隨意讓其(qi)退出運(yun)行，否則就會引發惡性(xing)事故(gu)。
