一、漏電開關的使用壽命以什么為限制

關(guan)于漏電開(kai)關(guan)的使(shi)用(yong)壽(shou)命，有很(hen)多(duo)(duo)人(ren)持不同的看法。有些(xie)人(ren)認(ren)為(wei)(wei)漏電開(kai)關(guan)的使(shi)用(yong)壽(shou)命應該是以使(shi)用(yong)次(ci)數為(wei)(wei)限(xian)(xian)制，也就(jiu)(jiu)是經(jing)過(guo)多(duo)(duo)少次(ci)使(shi)用(yong)后需要(yao)更(geng)換；而有些(xie)人(ren)則(ze)認(ren)為(wei)(wei)漏電開(kai)關(guan)的使(shi)用(yong)壽(shou)命應該是以年(nian)限(xian)(xian)為(wei)(wei)限(xian)(xian)制，也就(jiu)(jiu)是經(jing)過(guo)多(duo)(duo)少年(nian)后需要(yao)更(geng)換。

實(shi)際上，漏電開關(guan)的使用壽(shou)命應該是以時間(jian)為限制。由于漏電開關(guan)內(nei)部(bu)的電氣(qi)元(yuan)件和機械部(bu)件都會隨著時間(jian)的延(yan)長而發生老化、磨(mo)損等情況，因此漏電開關(guan)需要在(zai)一定的時間(jian)周期內(nei)更換(huan)，以保障其(qi)正常使用和保護作用。

二、漏電開關的壽命是多少年

一般來(lai)說(shuo)，漏電(dian)開關的使用(yong)壽命應該在5年左右(you)。當然(ran)，具體(ti)的使用(yong)壽命還會受到漏電(dian)開關的品牌、質量、環境條件等多種(zhong)因素(su)的影響，因此在實際使用(yong)中還需要根據具體(ti)情況進行判斷(duan)。

三、漏電開關如何保養和維護

1、定期清掃灰塵，保(bao)持(chi)漏電(dian)開(kai)關(guan)外殼(ke)及其(qi)上(shang)部件、連接(jie)端子(zi)的(de)清潔、完好和牢固連接(jie)；漏電(dian)開(kai)關(guan)外殼(ke)膠木件的(de)溫度不得超(chao)過65攝氏(shi)度，外殼(ke)金(jin)屬件溫度不得超(chao)過55攝氏(shi)度。同時，還(huan)要保(bao)持(chi)漏電(dian)開(kai)關(guan)操作手(shou)柄動作靈活、可靠(kao)。

2、漏電開關安裝場(chang)所應通風(feng)、干(gan)燥，有(you)預防(fang)雨淋、灰塵和(he)有(you)害氣體(ti)侵蝕的(de)措施。應盡量遠(yuan)離其他鐵磁(ci)體(ti)和(he)電流很(hen)大的(de)載流導體(ti)，避(bi)免(mian)磁(ci)場(chang)干(gan)擾。漏電開關安裝場(chang)所的(de)環(huan)境(jing)溫度(du)應在－5～40攝氏度(du)之(zhi)間。

3、至少應每月檢驗一(yi)次家用漏(lou)電(dian)(dian)開(kai)關(guan)動作(zuo)的可靠性。具體方(fang)法(fa)是：按(an)一(yi)下試驗按(an)鈕，如漏(lou)電(dian)(dian)開(kai)關(guan)正確斷開(kai)，說明正常；反之(zhi)，則說明漏(lou)電(dian)(dian)開(kai)關(guan)存在故障，應請有(you)經驗、有(you)資質的電(dian)(dian)工(gong)進行檢查(cha)更換。高溫(wen)多雨的夏(xia)秋(qiu)季節和農(nong)忙(mang)季節應增加試驗次數。

4、漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)使用(yong)一(yi)年后(hou)(hou)，應(ying)請專業電(dian)(dian)(dian)(dian)(dian)工對其進(jin)行檢(jian)修(xiu)，檢(jian)修(xiu)內容有(you)：測試保護(hu)器漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)動(dong)作值是(shi)否符合規定；檢(jian)查絕(jue)緣(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)一(yi)次電(dian)(dian)(dian)(dian)(dian)路(lu)各部絕(jue)緣(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)應(ying)在(zai)1．5兆歐以(yi)上；測量家(jia)庭室內線(xian)(xian)(xian)(xian)路(lu)漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，消(xiao)除各種(zhong)漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)隱患(huan)；檢(jian)查漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)接(jie)線(xian)(xian)(xian)(xian)及(ji)保護(hu)接(jie)地(di)裝置是(shi)否松動(dong)和接(jie)觸不(bu)良(liang)等。檢(jian)修(xiu)完畢(bi)后(hou)(hou)，應(ying)在(zai)現(xian)場(chang)進(jin)行一(yi)次實際模擬試驗。方法是(shi)，用(yong)一(yi)支(zhi)6千歐10瓦線(xian)(xian)(xian)(xian)繞電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，兩端各接(jie)一(yi)絕(jue)緣(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)，一(yi)頭(tou)插入插座的相線(xian)(xian)(xian)(xian)孔，另一(yi)頭(tou)與大地(di)連接(jie)，接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)與變壓(ya)器中性點接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)相同。這(zhe)時(shi)有(you)一(yi)約40毫安的漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，如果漏(lou)(lou)(lou)(lou)(lou)電(dian)(dian)(dian)(dian)(dian)開(kai)關(guan)立即跳閘，則(ze)可以(yi)放心使用(yong)。

5、漏電(dian)(dian)開關動(dong)作后(hou)不強(qiang)行送電(dian)(dian)。保(bao)護器動(dong)作后(hou)，若經檢(jian)(jian)查未發現(xian)事故(gu)點(dian)，允許試送電(dian)(dian)一次，如果再次動(dong)作，應查明(ming)原因，并采取相應措施處理(li)后(hou)方能恢復通電(dian)(dian)。尤其是(shi)漏電(dian)(dian)開關在檢(jian)(jian)測(ce)到漏電(dian)(dian)、短路現(xian)象后(hou)跳閘時(shi)，一定要查清和消除存(cun)在的電(dian)(dian)氣隱患，千(qian)萬不要隨意讓其退出運行，否則就(jiu)會引(yin)發惡性事故(gu)。
