一、漏電開關的使用壽命以什么為限制
關(guan)于漏(lou)電(dian)開關(guan)的使(shi)(shi)用壽(shou)命(ming)(ming),有很多人(ren)持不同的看法(fa)。有些人(ren)認為(wei)(wei)漏(lou)電(dian)開關(guan)的使(shi)(shi)用壽(shou)命(ming)(ming)應該(gai)(gai)是(shi)(shi)以使(shi)(shi)用次(ci)數(shu)為(wei)(wei)限制(zhi),也(ye)就是(shi)(shi)經過(guo)多少(shao)次(ci)使(shi)(shi)用后(hou)需要(yao)更(geng)換(huan);而有些人(ren)則認為(wei)(wei)漏(lou)電(dian)開關(guan)的使(shi)(shi)用壽(shou)命(ming)(ming)應該(gai)(gai)是(shi)(shi)以年(nian)限為(wei)(wei)限制(zhi),也(ye)就是(shi)(shi)經過(guo)多少(shao)年(nian)后(hou)需要(yao)更(geng)換(huan)。
實(shi)際上,漏(lou)電(dian)(dian)(dian)開(kai)關的使用壽命應該是以時間(jian)為限制。由于漏(lou)電(dian)(dian)(dian)開(kai)關內部(bu)的電(dian)(dian)(dian)氣元(yuan)件(jian)和(he)機械部(bu)件(jian)都會隨著(zhu)時間(jian)的延長而(er)發生老(lao)化、磨損等情況,因此漏(lou)電(dian)(dian)(dian)開(kai)關需要在一定的時間(jian)周期內更換,以保障其正(zheng)常使用和(he)保護作(zuo)用。
二、漏電開關的壽命是多少年
一般(ban)來說,漏(lou)電(dian)開關的使(shi)(shi)(shi)用(yong)壽(shou)命(ming)應該(gai)在5年左右。當然,具體(ti)的使(shi)(shi)(shi)用(yong)壽(shou)命(ming)還會受到(dao)漏(lou)電(dian)開關的品(pin)牌、質量、環(huan)境條件等多(duo)種因素(su)的影響,因此在實際使(shi)(shi)(shi)用(yong)中還需要根據(ju)具體(ti)情(qing)況進(jin)行判斷。
三、漏電開關如何保養和維護
1、定期清掃灰塵,保持漏電(dian)開(kai)關(guan)(guan)外殼及(ji)其(qi)上(shang)部件(jian)、連接(jie)端(duan)子的清潔(jie)、完好和牢固連接(jie);漏電(dian)開(kai)關(guan)(guan)外殼膠木件(jian)的溫(wen)度(du)不(bu)得超過(guo)65攝氏(shi)(shi)度(du),外殼金屬件(jian)溫(wen)度(du)不(bu)得超過(guo)55攝氏(shi)(shi)度(du)。同時,還要保持漏電(dian)開(kai)關(guan)(guan)操(cao)作手(shou)柄動作靈活、可靠。
2、漏電(dian)開關安裝(zhuang)場所應通風、干(gan)燥,有預防雨淋、灰(hui)塵和有害氣體(ti)侵蝕(shi)的措施。應盡(jin)量遠離其他(ta)鐵磁體(ti)和電(dian)流很大的載流導(dao)體(ti),避免磁場干(gan)擾。漏電(dian)開關安裝(zhuang)場所的環境(jing)溫(wen)度(du)應在(zai)-5~40攝氏度(du)之間。
3、至(zhi)少(shao)應(ying)(ying)每月檢驗(yan)一次家用漏電(dian)開(kai)(kai)關(guan)動作的(de)可靠性。具體(ti)方(fang)法是:按(an)一下(xia)試驗(yan)按(an)鈕,如(ru)漏電(dian)開(kai)(kai)關(guan)正確斷開(kai)(kai),說明正常;反(fan)之,則(ze)說明漏電(dian)開(kai)(kai)關(guan)存在故障(zhang),應(ying)(ying)請有經驗(yan)、有資質的(de)電(dian)工進行檢查更換。高溫多雨(yu)的(de)夏秋季(ji)節和(he)農忙季(ji)節應(ying)(ying)增加試驗(yan)次數。
4、漏電(dian)(dian)(dian)開(kai)(kai)關(guan)(guan)使用(yong)(yong)一(yi)年后(hou),應(ying)請專業電(dian)(dian)(dian)工對其(qi)進行檢(jian)修,檢(jian)修內容有:測(ce)試(shi)保護器漏電(dian)(dian)(dian)動(dong)作值是(shi)否符合規定;檢(jian)查絕(jue)(jue)(jue)緣電(dian)(dian)(dian)阻(zu),漏電(dian)(dian)(dian)開(kai)(kai)關(guan)(guan)一(yi)次(ci)電(dian)(dian)(dian)路各部絕(jue)(jue)(jue)緣電(dian)(dian)(dian)阻(zu)應(ying)在1.5兆(zhao)歐以(yi)上(shang);測(ce)量家庭室(shi)內線(xian)路漏電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu),消除各種漏電(dian)(dian)(dian)隱患;檢(jian)查漏電(dian)(dian)(dian)開(kai)(kai)關(guan)(guan)接(jie)(jie)線(xian)及保護接(jie)(jie)地(di)裝置是(shi)否松(song)動(dong)和接(jie)(jie)觸不良等。檢(jian)修完畢(bi)后(hou),應(ying)在現場(chang)進行一(yi)次(ci)實際模擬試(shi)驗(yan)。方法是(shi),用(yong)(yong)一(yi)支(zhi)6千歐10瓦線(xian)繞電(dian)(dian)(dian)阻(zu),兩端(duan)各接(jie)(jie)一(yi)絕(jue)(jue)(jue)緣電(dian)(dian)(dian)線(xian),一(yi)頭插(cha)入插(cha)座的相(xiang)線(xian)孔,另一(yi)頭與大地(di)連接(jie)(jie),接(jie)(jie)地(di)電(dian)(dian)(dian)阻(zu)與變壓器中(zhong)性點接(jie)(jie)地(di)電(dian)(dian)(dian)阻(zu)相(xiang)同。這時有一(yi)約(yue)40毫(hao)安的漏電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu),如(ru)果漏電(dian)(dian)(dian)開(kai)(kai)關(guan)(guan)立即跳閘,則(ze)可(ke)以(yi)放心(xin)使用(yong)(yong)。
5、漏電(dian)開關動(dong)作后不強(qiang)行送電(dian)。保護(hu)器動(dong)作后,若(ruo)經(jing)檢查(cha)(cha)未發現(xian)事故點,允許試送電(dian)一(yi)次,如(ru)果再次動(dong)作,應查(cha)(cha)明原(yuan)因,并采取相應措施處(chu)理后方(fang)能恢復通電(dian)。尤(you)其是漏電(dian)開關在檢測到漏電(dian)、短路現(xian)象后跳(tiao)閘時(shi),一(yi)定(ding)要查(cha)(cha)清和消除存(cun)在的電(dian)氣隱患,千萬不要隨意讓其退出運行,否則(ze)就會引發惡性事故。
