一、漏電開關的使用壽命以什么為限制

關(guan)于(yu)漏(lou)電開(kai)關(guan)的使(shi)用(yong)(yong)壽命(ming)，有很多人持不同(tong)的看(kan)法。有些(xie)人認為(wei)(wei)漏(lou)電開(kai)關(guan)的使(shi)用(yong)(yong)壽命(ming)應該是(shi)以使(shi)用(yong)(yong)次數為(wei)(wei)限制，也(ye)就(jiu)是(shi)經(jing)過(guo)多少次使(shi)用(yong)(yong)后需(xu)要更(geng)換；而(er)有些(xie)人則認為(wei)(wei)漏(lou)電開(kai)關(guan)的使(shi)用(yong)(yong)壽命(ming)應該是(shi)以年(nian)限為(wei)(wei)限制，也(ye)就(jiu)是(shi)經(jing)過(guo)多少年(nian)后需(xu)要更(geng)換。

實際上(shang)，漏(lou)電(dian)開(kai)關的(de)(de)使用(yong)(yong)壽(shou)命應該(gai)是(shi)以(yi)(yi)時(shi)間(jian)為限制。由于漏(lou)電(dian)開(kai)關內(nei)部(bu)的(de)(de)電(dian)氣元件和機(ji)械部(bu)件都(dou)會隨著時(shi)間(jian)的(de)(de)延長而發生老化、磨損等情況，因此漏(lou)電(dian)開(kai)關需(xu)要在一定的(de)(de)時(shi)間(jian)周期內(nei)更換，以(yi)(yi)保障其正(zheng)常使用(yong)(yong)和保護作(zuo)用(yong)(yong)。

二、漏電開關的壽命是多少年

一般來(lai)說(shuo)，漏(lou)電開(kai)關(guan)的(de)(de)使(shi)用(yong)(yong)(yong)壽(shou)命(ming)應該(gai)在5年左右。當然，具體的(de)(de)使(shi)用(yong)(yong)(yong)壽(shou)命(ming)還(huan)會受(shou)到(dao)漏(lou)電開(kai)關(guan)的(de)(de)品牌、質量、環境(jing)條件等多種因素(su)的(de)(de)影響，因此在實際使(shi)用(yong)(yong)(yong)中(zhong)還(huan)需(xu)要根據具體情況進行(xing)判(pan)斷(duan)。

三、漏電開關如何保養和維護

1、定期(qi)清(qing)掃灰塵，保(bao)持漏電(dian)開關(guan)(guan)外殼及其上(shang)部(bu)件(jian)、連(lian)接端子的清(qing)潔、完好和牢固連(lian)接；漏電(dian)開關(guan)(guan)外殼膠木件(jian)的溫(wen)(wen)度(du)不(bu)得(de)超(chao)過(guo)65攝氏度(du)，外殼金屬件(jian)溫(wen)(wen)度(du)不(bu)得(de)超(chao)過(guo)55攝氏度(du)。同時，還(huan)要保(bao)持漏電(dian)開關(guan)(guan)操(cao)作手柄動作靈活、可靠(kao)。

2、漏電(dian)(dian)開(kai)關安(an)裝場所應通風、干燥，有(you)預防(fang)雨淋、灰塵和(he)有(you)害氣體侵蝕的措施。應盡量遠離其他鐵磁體和(he)電(dian)(dian)流(liu)很大(da)的載流(liu)導體，避(bi)免磁場干擾。漏電(dian)(dian)開(kai)關安(an)裝場所的環(huan)境溫(wen)度(du)應在－5～40攝氏度(du)之間。

3、至少應每月檢(jian)驗一(yi)次家用漏電(dian)開關動作的(de)可靠性(xing)。具體(ti)方(fang)法是：按(an)一(yi)下試驗按(an)鈕，如漏電(dian)開關正確(que)斷開，說(shuo)明(ming)正常(chang)；反之，則說(shuo)明(ming)漏電(dian)開關存在故障，應請有(you)經驗、有(you)資質的(de)電(dian)工進行檢(jian)查(cha)更換。高溫多雨的(de)夏(xia)秋季(ji)節(jie)和農忙季(ji)節(jie)應增加試驗次數。

4、漏(lou)電(dian)(dian)(dian)(dian)開關使用一(yi)年(nian)后，應請專業電(dian)(dian)(dian)(dian)工對其進(jin)(jin)行檢(jian)修，檢(jian)修內(nei)容有：測試保護(hu)器漏(lou)電(dian)(dian)(dian)(dian)動(dong)作值是(shi)(shi)否符合規定；檢(jian)查絕(jue)(jue)緣(yuan)電(dian)(dian)(dian)(dian)阻，漏(lou)電(dian)(dian)(dian)(dian)開關一(yi)次電(dian)(dian)(dian)(dian)路(lu)各(ge)(ge)部絕(jue)(jue)緣(yuan)電(dian)(dian)(dian)(dian)阻應在1．5兆歐以上(shang)；測量家庭室內(nei)線路(lu)漏(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)，消除各(ge)(ge)種漏(lou)電(dian)(dian)(dian)(dian)隱患；檢(jian)查漏(lou)電(dian)(dian)(dian)(dian)開關接線及保護(hu)接地(di)裝置是(shi)(shi)否松動(dong)和接觸不(bu)良等(deng)。檢(jian)修完(wan)畢后，應在現場(chang)進(jin)(jin)行一(yi)次實際模擬試驗。方法是(shi)(shi)，用一(yi)支6千歐10瓦線繞電(dian)(dian)(dian)(dian)阻，兩端各(ge)(ge)接一(yi)絕(jue)(jue)緣(yuan)電(dian)(dian)(dian)(dian)線，一(yi)頭插入插座的(de)相線孔，另一(yi)頭與大地(di)連接，接地(di)電(dian)(dian)(dian)(dian)阻與變壓器中(zhong)性點(dian)接地(di)電(dian)(dian)(dian)(dian)阻相同。這時(shi)有一(yi)約40毫安的(de)漏(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)，如果漏(lou)電(dian)(dian)(dian)(dian)開關立即跳閘，則可以放心(xin)使用。

5、漏電(dian)(dian)(dian)開(kai)(kai)關動(dong)作后(hou)不強行(xing)送電(dian)(dian)(dian)。保(bao)護器動(dong)作后(hou)，若(ruo)經檢查未(wei)發(fa)現(xian)事故點，允許試送電(dian)(dian)(dian)一(yi)(yi)次，如果再次動(dong)作，應(ying)查明原因，并采取相(xiang)應(ying)措施處理后(hou)方能恢復(fu)通電(dian)(dian)(dian)。尤其是漏電(dian)(dian)(dian)開(kai)(kai)關在(zai)檢測(ce)到漏電(dian)(dian)(dian)、短路現(xian)象后(hou)跳閘時，一(yi)(yi)定要查清(qing)和消除存在(zai)的電(dian)(dian)(dian)氣隱患，千萬不要隨意讓其退出運(yun)行(xing)，否則就會(hui)引發(fa)惡性事故。
