一、漏電開關的使用壽命以什么為限制

關于漏(lou)電(dian)(dian)開關的(de)使(shi)用(yong)壽命，有(you)很多人(ren)(ren)持不同的(de)看法。有(you)些(xie)(xie)人(ren)(ren)認(ren)為(wei)漏(lou)電(dian)(dian)開關的(de)使(shi)用(yong)壽命應(ying)該是以使(shi)用(yong)次數為(wei)限(xian)(xian)制，也就是經過(guo)多少次使(shi)用(yong)后需(xu)要更換(huan)；而有(you)些(xie)(xie)人(ren)(ren)則認(ren)為(wei)漏(lou)電(dian)(dian)開關的(de)使(shi)用(yong)壽命應(ying)該是以年(nian)限(xian)(xian)為(wei)限(xian)(xian)制，也就是經過(guo)多少年(nian)后需(xu)要更換(huan)。

實際上，漏(lou)電(dian)(dian)開(kai)關(guan)的(de)使用(yong)壽命應該是以時(shi)間(jian)為限制。由于漏(lou)電(dian)(dian)開(kai)關(guan)內部(bu)的(de)電(dian)(dian)氣元(yuan)件(jian)(jian)和機(ji)械部(bu)件(jian)(jian)都會(hui)隨著時(shi)間(jian)的(de)延長而發生老化、磨損等情(qing)況，因此漏(lou)電(dian)(dian)開(kai)關(guan)需要在一定(ding)的(de)時(shi)間(jian)周(zhou)期內更(geng)換，以保(bao)障其正常(chang)使用(yong)和保(bao)護(hu)作用(yong)。

二、漏電開關的壽命是多少年

一般來說，漏電開關的使用(yong)壽命應該在(zai)5年左右。當然，具體的使用(yong)壽命還會受到漏電開關的品牌(pai)、質量、環境(jing)條件等(deng)多種因(yin)素的影響，因(yin)此在(zai)實際使用(yong)中還需要根據(ju)具體情況進行判斷。

三、漏電開關如何保養和維護

1、定期清掃灰塵，保(bao)持漏電開關外殼(ke)(ke)及其上部件、連(lian)接端子的清潔、完好(hao)和牢固連(lian)接；漏電開關外殼(ke)(ke)膠(jiao)木件的溫(wen)度不(bu)得超(chao)(chao)過65攝(she)氏度，外殼(ke)(ke)金屬件溫(wen)度不(bu)得超(chao)(chao)過55攝(she)氏度。同(tong)時，還要保(bao)持漏電開關操作手(shou)柄動作靈活、可靠。

2、漏(lou)電(dian)(dian)開關(guan)(guan)安裝場所(suo)應(ying)通風(feng)、干燥，有(you)預(yu)防雨淋、灰塵(chen)和有(you)害(hai)氣(qi)體侵蝕的措施。應(ying)盡量遠離其他(ta)鐵磁體和電(dian)(dian)流(liu)很大(da)的載流(liu)導體，避免(mian)磁場干擾。漏(lou)電(dian)(dian)開關(guan)(guan)安裝場所(suo)的環境溫度(du)應(ying)在－5～40攝氏度(du)之間。

3、至(zhi)少應每月檢驗(yan)(yan)一次家(jia)用漏電(dian)開(kai)關(guan)(guan)動作的可(ke)靠(kao)性。具體方法是：按一下(xia)試驗(yan)(yan)按鈕，如漏電(dian)開(kai)關(guan)(guan)正確斷(duan)開(kai)，說明(ming)正常；反(fan)之，則說明(ming)漏電(dian)開(kai)關(guan)(guan)存在故(gu)障，應請有(you)經(jing)驗(yan)(yan)、有(you)資質的電(dian)工(gong)進行檢查(cha)更換。高溫多(duo)雨的夏秋季節和(he)農忙季節應增加試驗(yan)(yan)次數。

4、漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)使用(yong)一(yi)(yi)(yi)(yi)年后，應請專業電(dian)(dian)(dian)(dian)(dian)工對其進(jin)行檢(jian)(jian)修(xiu)，檢(jian)(jian)修(xiu)內(nei)(nei)容有：測(ce)試(shi)保(bao)護器(qi)漏電(dian)(dian)(dian)(dian)(dian)動作值是否符合規定；檢(jian)(jian)查絕緣電(dian)(dian)(dian)(dian)(dian)阻，漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)一(yi)(yi)(yi)(yi)次電(dian)(dian)(dian)(dian)(dian)路(lu)各(ge)部絕緣電(dian)(dian)(dian)(dian)(dian)阻應在(zai)1．5兆歐以上(shang)；測(ce)量(liang)家庭室(shi)內(nei)(nei)線(xian)路(lu)漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，消除各(ge)種(zhong)漏電(dian)(dian)(dian)(dian)(dian)隱患(huan)；檢(jian)(jian)查漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)接(jie)線(xian)及保(bao)護接(jie)地(di)裝置是否松動和接(jie)觸不良等(deng)。檢(jian)(jian)修(xiu)完畢(bi)后，應在(zai)現(xian)場(chang)進(jin)行一(yi)(yi)(yi)(yi)次實(shi)際(ji)模(mo)擬試(shi)驗。方法(fa)是，用(yong)一(yi)(yi)(yi)(yi)支6千(qian)歐10瓦線(xian)繞電(dian)(dian)(dian)(dian)(dian)阻，兩端各(ge)接(jie)一(yi)(yi)(yi)(yi)絕緣電(dian)(dian)(dian)(dian)(dian)線(xian)，一(yi)(yi)(yi)(yi)頭(tou)(tou)插入(ru)插座的相(xiang)線(xian)孔，另一(yi)(yi)(yi)(yi)頭(tou)(tou)與大(da)地(di)連(lian)接(jie)，接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻與變(bian)壓(ya)器(qi)中性點接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)阻相(xiang)同。這時有一(yi)(yi)(yi)(yi)約40毫(hao)安(an)的漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，如果漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)立即跳閘，則可以放心(xin)使用(yong)。

5、漏(lou)電開(kai)(kai)關動(dong)作(zuo)(zuo)后(hou)不(bu)強行(xing)送電。保護器動(dong)作(zuo)(zuo)后(hou)，若經檢查未發(fa)現事(shi)故(gu)點(dian)，允許試送電一次，如(ru)果(guo)再次動(dong)作(zuo)(zuo)，應(ying)查明原因，并采(cai)取(qu)相(xiang)應(ying)措施處理后(hou)方能恢復通電。尤其是(shi)漏(lou)電開(kai)(kai)關在檢測到(dao)漏(lou)電、短(duan)路(lu)現象(xiang)后(hou)跳閘時，一定要(yao)查清和消除存在的(de)電氣隱患，千萬不(bu)要(yao)隨(sui)意讓其退出(chu)運行(xing)，否(fou)則(ze)就會(hui)引發(fa)惡性(xing)事(shi)故(gu)。
