一、漏電開關的使用壽命以什么為限制
關(guan)于漏(lou)(lou)(lou)電(dian)(dian)開關(guan)的(de)使用(yong)壽(shou)(shou)命,有很(hen)多(duo)人(ren)持不(bu)同的(de)看(kan)法。有些(xie)人(ren)認為漏(lou)(lou)(lou)電(dian)(dian)開關(guan)的(de)使用(yong)壽(shou)(shou)命應(ying)該(gai)是以(yi)使用(yong)次數為限制,也就是經(jing)過多(duo)少(shao)次使用(yong)后需要更換;而有些(xie)人(ren)則認為漏(lou)(lou)(lou)電(dian)(dian)開關(guan)的(de)使用(yong)壽(shou)(shou)命應(ying)該(gai)是以(yi)年限為限制,也就是經(jing)過多(duo)少(shao)年后需要更換。
實際上,漏電開關(guan)的(de)使用(yong)壽命應該是以時(shi)間為限制。由于漏電開關(guan)內部的(de)電氣(qi)元件和機(ji)械(xie)部件都會隨著(zhu)時(shi)間的(de)延長而(er)發(fa)生老化、磨損等情況,因此漏電開關(guan)需要在一(yi)定(ding)的(de)時(shi)間周期內更換,以保障其正常使用(yong)和保護作用(yong)。
二、漏電開關的壽命是多少年
一般來說,漏電開關的(de)使(shi)(shi)用壽命應該(gai)在5年左右(you)。當然,具體的(de)使(shi)(shi)用壽命還(huan)會受(shou)到漏電開關的(de)品牌、質(zhi)量、環境條件(jian)等(deng)多(duo)種因素的(de)影響,因此(ci)在實際使(shi)(shi)用中還(huan)需(xu)要(yao)根據(ju)具體情況進行判(pan)斷。
三、漏電開關如何保養和維護
1、定期清(qing)掃灰塵(chen),保(bao)持漏電(dian)開(kai)關外殼及其上(shang)部件、連接端子的清(qing)潔、完好和牢固連接;漏電(dian)開(kai)關外殼膠木件的溫度(du)不得超過(guo)(guo)65攝氏(shi)度(du),外殼金屬件溫度(du)不得超過(guo)(guo)55攝氏(shi)度(du)。同(tong)時,還(huan)要保(bao)持漏電(dian)開(kai)關操作(zuo)手柄動作(zuo)靈(ling)活、可(ke)靠。
2、漏(lou)電開(kai)關安(an)裝(zhuang)場所應通風、干(gan)燥,有預(yu)防雨淋、灰塵(chen)和(he)有害氣體(ti)侵蝕(shi)的措施。應盡量遠離(li)其他鐵磁體(ti)和(he)電流很大的載流導體(ti),避(bi)免磁場干(gan)擾。漏(lou)電開(kai)關安(an)裝(zhuang)場所的環(huan)境溫(wen)度(du)應在(zai)-5~40攝氏度(du)之間。
3、至(zhi)少應每月檢(jian)驗(yan)一次家用漏電開(kai)(kai)關動作的可靠性。具體方(fang)法是:按一下試(shi)驗(yan)按鈕,如漏電開(kai)(kai)關正(zheng)確斷開(kai)(kai),說明正(zheng)常(chang);反之,則說明漏電開(kai)(kai)關存在故障,應請有經驗(yan)、有資(zi)質的電工進行(xing)檢(jian)查更換。高溫(wen)多雨(yu)的夏秋季(ji)節(jie)和農忙季(ji)節(jie)應增加試(shi)驗(yan)次數。
4、漏(lou)(lou)電(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)使用一(yi)(yi)年后,應(ying)請專業電(dian)(dian)(dian)(dian)工對其(qi)進(jin)(jin)行(xing)檢(jian)修(xiu),檢(jian)修(xiu)內(nei)容有(you):測(ce)試保護器(qi)漏(lou)(lou)電(dian)(dian)(dian)(dian)動作值(zhi)是否(fou)符合規定;檢(jian)查絕(jue)(jue)緣電(dian)(dian)(dian)(dian)阻(zu)(zu),漏(lou)(lou)電(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)一(yi)(yi)次電(dian)(dian)(dian)(dian)路(lu)各部(bu)絕(jue)(jue)緣電(dian)(dian)(dian)(dian)阻(zu)(zu)應(ying)在1.5兆(zhao)歐以(yi)上;測(ce)量家(jia)庭室內(nei)線路(lu)漏(lou)(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu),消除(chu)各種漏(lou)(lou)電(dian)(dian)(dian)(dian)隱患(huan);檢(jian)查漏(lou)(lou)電(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)接(jie)(jie)線及(ji)保護接(jie)(jie)地(di)(di)裝(zhuang)置是否(fou)松動和(he)接(jie)(jie)觸不良等。檢(jian)修(xiu)完畢后,應(ying)在現場(chang)進(jin)(jin)行(xing)一(yi)(yi)次實際(ji)模擬試驗。方法是,用一(yi)(yi)支6千歐10瓦(wa)線繞電(dian)(dian)(dian)(dian)阻(zu)(zu),兩端各接(jie)(jie)一(yi)(yi)絕(jue)(jue)緣電(dian)(dian)(dian)(dian)線,一(yi)(yi)頭插(cha)入插(cha)座的相線孔,另一(yi)(yi)頭與大地(di)(di)連接(jie)(jie),接(jie)(jie)地(di)(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)與變壓器(qi)中性點(dian)接(jie)(jie)地(di)(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)相同。這時有(you)一(yi)(yi)約(yue)40毫安的漏(lou)(lou)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu),如果漏(lou)(lou)電(dian)(dian)(dian)(dian)開(kai)(kai)關(guan)立即跳閘,則可以(yi)放心使用。
5、漏電(dian)開(kai)關(guan)動(dong)作后不強行送(song)電(dian)。保護器(qi)動(dong)作后,若(ruo)經檢查未發現事故點,允許試送(song)電(dian)一(yi)次,如(ru)果(guo)再次動(dong)作,應查明原(yuan)因,并(bing)采取相應措(cuo)施處理(li)后方(fang)能恢復通(tong)電(dian)。尤(you)其是漏電(dian)開(kai)關(guan)在(zai)檢測(ce)到漏電(dian)、短路現象后跳閘時,一(yi)定(ding)要(yao)查清(qing)和消除存(cun)在(zai)的電(dian)氣隱患,千萬不要(yao)隨意讓其退出(chu)運行,否(fou)則就會引發惡性事故。
