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(de)使(shi)(shi)(shi)(shi)用(yong)壽(shou)命,有(you)很多人持不(bu)同的(de)看法。有(you)些人認為(wei)漏電(dian)開(kai)關(guan)的(de)使(shi)(shi)(shi)(shi)用(yong)壽(shou)命應(ying)該是以(yi)使(shi)(shi)(shi)(shi)用(yong)次數為(wei)限(xian)(xian)制(zhi),也就是經(jing)過多少(shao)次使(shi)(shi)(shi)(shi)用(yong)后需要更換;而有(you)些人則認為(wei)漏電(dian)開(kai)關(guan)的(de)使(shi)(shi)(shi)(shi)用(yong)壽(shou)命應(ying)該是以(yi)年限(xian)(xian)為(wei)限(xian)(xian)制(zhi),也就是經(jing)過多少(shao)年后需要更換。
實際(ji)上,漏電(dian)(dian)(dian)開關(guan)(guan)的使用壽命應該(gai)是以(yi)時(shi)間為限制。由于漏電(dian)(dian)(dian)開關(guan)(guan)內部的電(dian)(dian)(dian)氣(qi)元件和機械(xie)部件都會(hui)隨著時(shi)間的延長而發生老化、磨(mo)損等情(qing)況,因此漏電(dian)(dian)(dian)開關(guan)(guan)需(xu)要在一定的時(shi)間周期內更(geng)換,以(yi)保(bao)(bao)障其正(zheng)常(chang)使用和保(bao)(bao)護作用。
二、漏電開關的壽命是多少年
一(yi)般來說(shuo),漏(lou)(lou)電(dian)開關的(de)使(shi)(shi)用壽命(ming)應該在5年左右。當然(ran),具體的(de)使(shi)(shi)用壽命(ming)還(huan)會受到(dao)漏(lou)(lou)電(dian)開關的(de)品牌(pai)、質量、環(huan)境條件等(deng)多種因(yin)素的(de)影響(xiang),因(yin)此在實際使(shi)(shi)用中(zhong)還(huan)需要根據具體情況進行(xing)判斷。
三、漏電開關如何保養和維護
1、定期清(qing)掃灰塵,保持漏電開(kai)關(guan)(guan)外殼(ke)(ke)及(ji)其上部件、連(lian)接端子的(de)清(qing)潔(jie)、完好(hao)和牢固連(lian)接;漏電開(kai)關(guan)(guan)外殼(ke)(ke)膠木件的(de)溫(wen)度(du)不(bu)得超過65攝(she)氏度(du),外殼(ke)(ke)金屬件溫(wen)度(du)不(bu)得超過55攝(she)氏度(du)。同時,還要保持漏電開(kai)關(guan)(guan)操作手柄動作靈活、可(ke)靠。
2、漏電(dian)開(kai)關(guan)安(an)裝場(chang)所應(ying)(ying)通風(feng)、干燥,有(you)預(yu)防(fang)雨淋(lin)、灰(hui)塵和有(you)害氣體(ti)(ti)侵蝕(shi)的(de)措施。應(ying)(ying)盡(jin)量(liang)遠(yuan)離其他鐵(tie)磁體(ti)(ti)和電(dian)流很大的(de)載流導體(ti)(ti),避免(mian)磁場(chang)干擾(rao)。漏電(dian)開(kai)關(guan)安(an)裝場(chang)所的(de)環境溫度(du)應(ying)(ying)在-5~40攝氏度(du)之間。
3、至少應每(mei)月檢驗(yan)一次(ci)家用漏(lou)電開關(guan)動作(zuo)的可靠性。具體方法(fa)是:按一下(xia)試(shi)驗(yan)按鈕,如(ru)漏(lou)電開關(guan)正確斷開,說明(ming)正常(chang);反之,則說明(ming)漏(lou)電開關(guan)存在(zai)故障(zhang),應請有經驗(yan)、有資(zi)質的電工進行檢查更(geng)換。高溫多雨(yu)的夏(xia)秋季(ji)節(jie)和農忙(mang)季(ji)節(jie)應增加試(shi)驗(yan)次(ci)數。
4、漏電(dian)(dian)(dian)(dian)開(kai)關(guan)使(shi)用(yong)(yong)一(yi)(yi)年后,應請專業電(dian)(dian)(dian)(dian)工對其進行檢(jian)修,檢(jian)修內容有:測(ce)試保護器漏電(dian)(dian)(dian)(dian)動作值(zhi)是(shi)(shi)否符合(he)規定;檢(jian)查(cha)絕緣電(dian)(dian)(dian)(dian)阻,漏電(dian)(dian)(dian)(dian)開(kai)關(guan)一(yi)(yi)次電(dian)(dian)(dian)(dian)路(lu)各部絕緣電(dian)(dian)(dian)(dian)阻應在1.5兆歐以上;測(ce)量家庭(ting)室(shi)內線(xian)(xian)(xian)路(lu)漏電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu),消(xiao)除各種(zhong)漏電(dian)(dian)(dian)(dian)隱(yin)患;檢(jian)查(cha)漏電(dian)(dian)(dian)(dian)開(kai)關(guan)接(jie)線(xian)(xian)(xian)及保護接(jie)地(di)裝(zhuang)置是(shi)(shi)否松動和(he)接(jie)觸不良等(deng)。檢(jian)修完畢后,應在現場進行一(yi)(yi)次實際模(mo)擬試驗。方法是(shi)(shi),用(yong)(yong)一(yi)(yi)支6千歐10瓦線(xian)(xian)(xian)繞(rao)電(dian)(dian)(dian)(dian)阻,兩(liang)端各接(jie)一(yi)(yi)絕緣電(dian)(dian)(dian)(dian)線(xian)(xian)(xian),一(yi)(yi)頭插(cha)入插(cha)座(zuo)的(de)相線(xian)(xian)(xian)孔,另一(yi)(yi)頭與大地(di)連接(jie),接(jie)地(di)電(dian)(dian)(dian)(dian)阻與變壓器中性點接(jie)地(di)電(dian)(dian)(dian)(dian)阻相同(tong)。這時有一(yi)(yi)約40毫安的(de)漏電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu),如(ru)果漏電(dian)(dian)(dian)(dian)開(kai)關(guan)立即跳閘,則可以放心(xin)使(shi)用(yong)(yong)。
5、漏(lou)電開關動(dong)作(zuo)后(hou)不強(qiang)行(xing)送電。保護器(qi)動(dong)作(zuo)后(hou),若(ruo)經檢查未(wei)發(fa)(fa)現事故點,允許試(shi)送電一(yi)次(ci),如果再次(ci)動(dong)作(zuo),應查明原因,并(bing)采取相應措施處理后(hou)方能恢(hui)復通電。尤其(qi)是漏(lou)電開關在檢測到漏(lou)電、短路現象后(hou)跳閘時,一(yi)定要查清(qing)和消(xiao)除存(cun)在的電氣隱患,千萬(wan)不要隨意(yi)讓其(qi)退出運行(xing),否則就會(hui)引發(fa)(fa)惡性事故。
