山西高壓配電柜容易出(chu)現故(gu)障(zhang)的(de)元器件有哪些？
高(gao)(gao)壓(ya)(ya)配電(dian)(dian)(dian)柜是指用于電(dian)(dian)(dian)力系統發電(dian)(dian)(dian)、輸電(dian)(dian)(dian)、配電(dian)(dian)(dian)、電(dian)(dian)(dian)能轉換和消耗中起(qi)通斷、控制(zhi)或(huo)保護等作用，電(dian)(dian)(dian)壓(ya)(ya)等級在3.6kV~550kV的電(dian)(dian)(dian)器產品，主要包(bao)括高(gao)(gao)壓(ya)(ya)斷路器、高(gao)(gao)壓(ya)(ya)隔離(li)開(kai)(kai)關與接地開(kai)(kai)關、高(gao)(gao)壓(ya)(ya)負荷(he)開(kai)(kai)關、高(gao)(gao)壓(ya)(ya)自動重合與分段器，高(gao)(gao)壓(ya)(ya)操作機(ji)構、高(gao)(gao)壓(ya)(ya)防爆配電(dian)(dian)(dian)裝置等幾大(da)類。
通(tong)常高(gao)壓(ya)配(pei)(pei)電柜出(chu)現故(gu)障(zhang)，往(wang)往(wang)是(shi)其中一個(ge)或者幾個(ge)元(yuan)器件出(chu)現了故(gu)障(zhang)，從而影響了整(zheng)(zheng)體的運行。山西(xi)高(gao)壓(ya)配(pei)(pei)電柜容易出(chu)現故(gu)障(zhang)的元(yuan)器件有哪些？山西(xi)景泰電氣配(pei)(pei)電柜為您整(zheng)(zheng)理介紹：
1、電(dian)纜(lan)：電(dian)纜(lan)故(gu)障一般都是相間短路，即使是單相短路，由于放電(dian)時(shi)間長，也會慢慢演(yan)變為(wei)兩(liang)相或(huo)三相短路。這時(shi)候(hou)需要(yao)排查故(gu)障點，處理(li)好故(gu)障時(shi)候(hou)才能通電(dian)，否則會燒壞更多的設備。
2、電(dian)壓互(hu)(hu)感器(qi)：電(dian)壓互(hu)(hu)感器(qi)故障通常導(dao)致(zhi)(zhi)的(de)(de)結果是一(yi)次(ci)側熔(rong)(rong)(rong)(rong)絲熔(rong)(rong)(rong)(rong)斷，電(dian)壓互(hu)(hu)感器(qi)內部發生(sheng)匝間(jian)、層間(jian)、相間(jian)及(ji)一(yi)相接地都有可能(neng)導(dao)致(zhi)(zhi)一(yi)次(ci)側熔(rong)(rong)(rong)(rong)絲熔(rong)(rong)(rong)(rong)斷。電(dian)壓互(hu)(hu)感器(qi)二(er)次(ci)側故障時，如果二(er)次(ci)側熔(rong)(rong)(rong)(rong)絲選配過大(da)，也容(rong)易導(dao)致(zhi)(zhi)一(yi)次(ci)側熔(rong)(rong)(rong)(rong)斷器(qi)燒(shao)壞。10kv電(dian)源一(yi)相接地，另外(wai)兩相的(de)(de)對地電(dian)壓會(hui)增加為(wei)根號三倍，從而導(dao)致(zhi)(zhi)電(dian)流變(bian)大(da)，也會(hui)燒(shao)壞熔(rong)(rong)(rong)(rong)絲。
3、電(dian)流(liu)互(hu)感(gan)器(qi)(qi)：電(dian)流(liu)互(hu)感(gan)器(qi)(qi)的(de)故障(zhang)通常(chang)是鐵(tie)芯過熱，嚴重時(shi)容易炸裂(lie)互(hu)感(gan)器(qi)(qi)。電(dian)流(liu)互(hu)感(gan)器(qi)(qi)運行中(zhong)如果出現過負荷、二次開(kai)路(lu)或絕緣損壞引發放電(dian)，都會造成聲音異響(xiang)，這時(shi)候需要(yao)分析原因，采取相應(ying)措施解決故障(zhang)。
4、避(bi)(bi)雷器(qi)：避(bi)(bi)雷器(qi)作為保(bao)護開關設(she)備的主要元器(qi)件要定期檢修，通常避(bi)(bi)雷器(qi)故障有(you)磁絕緣損壞或(huo)者直(zhi)接炸了，避(bi)(bi)雷器(qi)一旦出現故障要及時更換。
