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)的使用壽命(ming)，有(you)很多人持不(bu)同的看法。有(you)些人認為(wei)(wei)(wei)漏電(dian)開(kai)關(guan)的使用壽命(ming)應該(gai)是(shi)以(yi)(yi)使用次(ci)數為(wei)(wei)(wei)限制(zhi)，也就(jiu)是(shi)經過(guo)多少次(ci)使用后(hou)需要(yao)更(geng)(geng)換；而(er)有(you)些人則認為(wei)(wei)(wei)漏電(dian)開(kai)關(guan)的使用壽命(ming)應該(gai)是(shi)以(yi)(yi)年限為(wei)(wei)(wei)限制(zhi)，也就(jiu)是(shi)經過(guo)多少年后(hou)需要(yao)更(geng)(geng)換。

實際上，漏電(dian)(dian)開關(guan)的使(shi)用壽(shou)命應該是以(yi)時間為限(xian)制。由(you)于漏電(dian)(dian)開關(guan)內(nei)部的電(dian)(dian)氣元件和(he)機械部件都會隨著時間的延長而發生老化(hua)、磨損等情況(kuang)，因此漏電(dian)(dian)開關(guan)需要在一定(ding)的時間周期內(nei)更換，以(yi)保(bao)障(zhang)其正常使(shi)用和(he)保(bao)護作用。

二、漏電開關的壽命是多少年

一般來說，漏電開(kai)關的(de)使(shi)(shi)用壽命(ming)應該在5年左右。當(dang)然，具體(ti)的(de)使(shi)(shi)用壽命(ming)還會受到漏電開(kai)關的(de)品牌、質量(liang)、環境條件等多種因(yin)素的(de)影響，因(yin)此在實際(ji)使(shi)(shi)用中還需要根據具體(ti)情況進行(xing)判斷(duan)。

三、漏電開關如何保養和維護

1、定期清(qing)掃(sao)灰塵，保持(chi)漏電(dian)開關(guan)外(wai)殼及(ji)其(qi)上(shang)部(bu)件(jian)、連接(jie)端子的清(qing)潔、完好(hao)和牢固連接(jie)；漏電(dian)開關(guan)外(wai)殼膠木件(jian)的溫度不得超過65攝氏(shi)度，外(wai)殼金屬(shu)件(jian)溫度不得超過55攝氏(shi)度。同時，還要保持(chi)漏電(dian)開關(guan)操(cao)作(zuo)手(shou)柄(bing)動(dong)作(zuo)靈活、可靠。

2、漏電(dian)開(kai)關(guan)安裝場(chang)(chang)所(suo)應通風(feng)、干燥，有預(yu)防雨淋、灰塵和有害氣體(ti)侵蝕的措施。應盡量(liang)遠離其他鐵磁體(ti)和電(dian)流很大的載流導(dao)體(ti)，避免磁場(chang)(chang)干擾(rao)。漏電(dian)開(kai)關(guan)安裝場(chang)(chang)所(suo)的環境溫度(du)應在－5～40攝氏(shi)度(du)之間(jian)。

3、至少應(ying)每月檢驗(yan)一(yi)次(ci)家用漏(lou)電開(kai)關(guan)動作的(de)可靠(kao)性。具體方(fang)法是：按一(yi)下試(shi)驗(yan)按鈕(niu)，如漏(lou)電開(kai)關(guan)正(zheng)確斷(duan)開(kai)，說明正(zheng)常；反之，則說明漏(lou)電開(kai)關(guan)存在故障，應(ying)請有(you)經驗(yan)、有(you)資質(zhi)的(de)電工進行檢查更(geng)換。高溫多雨(yu)的(de)夏秋季(ji)節(jie)和農忙季(ji)節(jie)應(ying)增加(jia)試(shi)驗(yan)次(ci)數。

4、漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關使用一(yi)(yi)(yi)年后(hou)，應請(qing)專業(ye)電(dian)(dian)(dian)(dian)(dian)工對其進行檢修(xiu)(xiu)，檢修(xiu)(xiu)內容有(you)：測試(shi)(shi)保(bao)護器漏電(dian)(dian)(dian)(dian)(dian)動作值是否符合規定；檢查絕緣電(dian)(dian)(dian)(dian)(dian)阻，漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關一(yi)(yi)(yi)次(ci)(ci)電(dian)(dian)(dian)(dian)(dian)路(lu)各(ge)(ge)(ge)部(bu)絕緣電(dian)(dian)(dian)(dian)(dian)阻應在(zai)1．5兆歐(ou)以上(shang)；測量家庭室(shi)內線(xian)(xian)路(lu)漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，消除各(ge)(ge)(ge)種漏電(dian)(dian)(dian)(dian)(dian)隱患；檢查漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關接線(xian)(xian)及保(bao)護接地裝置(zhi)是否松動和(he)接觸不良(liang)等。檢修(xiu)(xiu)完畢后(hou)，應在(zai)現場進行一(yi)(yi)(yi)次(ci)(ci)實際模擬(ni)試(shi)(shi)驗。方法是，用一(yi)(yi)(yi)支6千歐(ou)10瓦(wa)線(xian)(xian)繞電(dian)(dian)(dian)(dian)(dian)阻，兩端各(ge)(ge)(ge)接一(yi)(yi)(yi)絕緣電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)，一(yi)(yi)(yi)頭(tou)插(cha)入(ru)插(cha)座的相(xiang)線(xian)(xian)孔，另一(yi)(yi)(yi)頭(tou)與大地連接，接地電(dian)(dian)(dian)(dian)(dian)阻與變壓(ya)器中性點接地電(dian)(dian)(dian)(dian)(dian)阻相(xiang)同(tong)。這時有(you)一(yi)(yi)(yi)約(yue)40毫安(an)的漏電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，如(ru)果漏電(dian)(dian)(dian)(dian)(dian)開(kai)(kai)關立即跳(tiao)閘，則可(ke)以放心使用。

5、漏電(dian)(dian)(dian)開關(guan)動作后(hou)不強行送(song)(song)電(dian)(dian)(dian)。保護器(qi)動作后(hou)，若經檢查未發現事故點(dian)，允(yun)許(xu)試送(song)(song)電(dian)(dian)(dian)一次，如果(guo)再次動作，應(ying)查明(ming)原(yuan)因，并采(cai)取相應(ying)措(cuo)施(shi)處理后(hou)方能恢復通電(dian)(dian)(dian)。尤其是漏電(dian)(dian)(dian)開關(guan)在檢測(ce)到漏電(dian)(dian)(dian)、短(duan)路現象(xiang)后(hou)跳閘時，一定(ding)要查清(qing)和消除(chu)存在的電(dian)(dian)(dian)氣隱患(huan)，千萬(wan)不要隨意讓其退出運(yun)行，否則就(jiu)會引(yin)發惡性事故。
