一、漏電開關的使用壽命以什么為限制
關于漏(lou)(lou)(lou)電開關的使(shi)(shi)用(yong)壽命,有(you)很(hen)多(duo)人(ren)(ren)持不同(tong)的看法。有(you)些人(ren)(ren)認為(wei)漏(lou)(lou)(lou)電開關的使(shi)(shi)用(yong)壽命應該(gai)是(shi)以(yi)使(shi)(shi)用(yong)次(ci)數為(wei)限制,也(ye)就(jiu)是(shi)經過多(duo)少次(ci)使(shi)(shi)用(yong)后需要(yao)(yao)更(geng)(geng)換;而有(you)些人(ren)(ren)則認為(wei)漏(lou)(lou)(lou)電開關的使(shi)(shi)用(yong)壽命應該(gai)是(shi)以(yi)年限為(wei)限制,也(ye)就(jiu)是(shi)經過多(duo)少年后需要(yao)(yao)更(geng)(geng)換。
實際(ji)上,漏電開關(guan)的(de)使用壽命(ming)應該是以(yi)時間(jian)為限制。由于漏電開關(guan)內(nei)部的(de)電氣元件和機械部件都(dou)會隨著時間(jian)的(de)延(yan)長而發生(sheng)老化、磨損等情況(kuang),因此(ci)漏電開關(guan)需(xu)要在一定的(de)時間(jian)周期內(nei)更換,以(yi)保(bao)障其正常使用和保(bao)護作用。
二、漏電開關的壽命是多少年
一般來說,漏電開關(guan)的使用(yong)壽(shou)命(ming)應該在(zai)5年左右。當(dang)然,具體(ti)的使用(yong)壽(shou)命(ming)還(huan)會受到漏電開關(guan)的品牌、質量、環境條件等多種因素的影響,因此在(zai)實際使用(yong)中還(huan)需要(yao)根據具體(ti)情況(kuang)進行判(pan)斷。
三、漏電開關如何保養和維護
1、定期清掃灰塵(chen),保持(chi)漏電(dian)開關(guan)外(wai)殼(ke)及其上部件、連(lian)接端子(zi)的(de)清潔(jie)、完好和牢固連(lian)接;漏電(dian)開關(guan)外(wai)殼(ke)膠(jiao)木件的(de)溫度(du)不得超過65攝(she)氏(shi)(shi)度(du),外(wai)殼(ke)金屬件溫度(du)不得超過55攝(she)氏(shi)(shi)度(du)。同時,還要保持(chi)漏電(dian)開關(guan)操作(zuo)手柄動作(zuo)靈(ling)活、可靠。
2、漏電(dian)開(kai)關安(an)裝(zhuang)場所應(ying)通風、干(gan)燥,有預防雨淋、灰(hui)塵和有害氣體侵蝕的(de)措(cuo)施。應(ying)盡量遠(yuan)離其他鐵磁體和電(dian)流很大的(de)載(zai)流導體,避免磁場干(gan)擾(rao)。漏電(dian)開(kai)關安(an)裝(zhuang)場所的(de)環境溫度應(ying)在-5~40攝氏度之間。
3、至少應(ying)每月檢驗一次(ci)家用漏電(dian)開關(guan)動作的可(ke)靠性。具體方法是:按(an)一下試驗按(an)鈕,如漏電(dian)開關(guan)正確斷(duan)開,說明(ming)正常(chang);反之,則說明(ming)漏電(dian)開關(guan)存在故障,應(ying)請有經驗、有資質(zhi)的電(dian)工(gong)進(jin)行檢查更換。高溫多雨的夏秋季節和農忙季節應(ying)增加試驗次(ci)數。
4、漏(lou)(lou)電(dian)(dian)(dian)(dian)開關(guan)使用一年后(hou)(hou),應請(qing)專(zhuan)業電(dian)(dian)(dian)(dian)工對其進行(xing)檢(jian)修,檢(jian)修內(nei)容有:測試(shi)保護器(qi)漏(lou)(lou)電(dian)(dian)(dian)(dian)動作值(zhi)是(shi)(shi)否符(fu)合規定;檢(jian)查絕緣(yuan)電(dian)(dian)(dian)(dian)阻,漏(lou)(lou)電(dian)(dian)(dian)(dian)開關(guan)一次(ci)(ci)電(dian)(dian)(dian)(dian)路(lu)各部絕緣(yuan)電(dian)(dian)(dian)(dian)阻應在1.5兆歐以(yi)上(shang);測量家庭室內(nei)線(xian)路(lu)漏(lou)(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流,消除各種(zhong)漏(lou)(lou)電(dian)(dian)(dian)(dian)隱患;檢(jian)查漏(lou)(lou)電(dian)(dian)(dian)(dian)開關(guan)接(jie)(jie)線(xian)及保護接(jie)(jie)地(di)(di)裝置(zhi)是(shi)(shi)否松動和接(jie)(jie)觸不良等。檢(jian)修完畢后(hou)(hou),應在現場進行(xing)一次(ci)(ci)實際模擬試(shi)驗。方法是(shi)(shi),用一支6千歐10瓦線(xian)繞電(dian)(dian)(dian)(dian)阻,兩端(duan)各接(jie)(jie)一絕緣(yuan)電(dian)(dian)(dian)(dian)線(xian),一頭(tou)(tou)插入(ru)插座的相線(xian)孔,另一頭(tou)(tou)與大(da)地(di)(di)連接(jie)(jie),接(jie)(jie)地(di)(di)電(dian)(dian)(dian)(dian)阻與變壓(ya)器(qi)中(zhong)性點接(jie)(jie)地(di)(di)電(dian)(dian)(dian)(dian)阻相同。這(zhe)時有一約40毫安的漏(lou)(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流,如果漏(lou)(lou)電(dian)(dian)(dian)(dian)開關(guan)立(li)即跳閘,則可以(yi)放(fang)心使用。
5、漏(lou)(lou)電(dian)開關動作(zuo)后(hou)不(bu)強行(xing)送(song)(song)電(dian)。保護器動作(zuo)后(hou),若(ruo)經檢查未發(fa)現事故點,允許試送(song)(song)電(dian)一(yi)次,如果再次動作(zuo),應(ying)查明原因,并采取相應(ying)措施處理后(hou)方能恢復通電(dian)。尤(you)其(qi)是漏(lou)(lou)電(dian)開關在檢測到漏(lou)(lou)電(dian)、短路現象(xiang)后(hou)跳閘時,一(yi)定要查清和消(xiao)除(chu)存在的電(dian)氣隱(yin)患,千萬不(bu)要隨意讓其(qi)退出運行(xing),否(fou)則就會引(yin)發(fa)惡性(xing)事故。
