rvvp屏(ping)(ping)蔽(bi)(bi)線(xian)是一(yi)種性(xing)能較好的耐(nai)(nai)火rvvp屏(ping)(ping)蔽(bi)(bi)線(xian)。它由銅(tong)芯，銅(tong)護套和氧化鎂絕緣材(cai)料加工而(er)成(cheng)，簡稱為MIrvvp屏(ping)(ping)蔽(bi)(bi)線(xian)。該rvvp屏(ping)(ping)蔽(bi)(bi)線(xian)是完全由無(wu)機材(cai)料組成(cheng)的耐(nai)(nai)火層(ceng)，而(er)普通耐(nai)(nai)火rvvp屏(ping)(ping)蔽(bi)(bi)線(xian)的耐(nai)(nai)火層(ceng)是無(wu)機材(cai)料和一(yi)般有(you)機材(cai)料的復合材(cai)料。

2.rvvp屏蔽線運(yun)行維護過(guo)程中易出(chu)現問題

rvvp屏(ping)蔽(bi)線(xian)系(xi)統在運(yun)(yun)行(xing)(xing)(xing)(xing)的(de)(de)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)，由(you)(you)于(yu)自身性(xing)質(zhi)特點(dian)和(he)(he)敷(fu)設過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)的(de)(de)敷(fu)設方式問(wen)題(ti)(ti)；在運(yun)(yun)行(xing)(xing)(xing)(xing)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)外界環境的(de)(de)影響導致(zhi)rvvp屏(ping)蔽(bi)線(xian)運(yun)(yun)行(xing)(xing)(xing)(xing)出(chu)現(xian)故(gu)障問(wen)題(ti)(ti)。其中(zhong)(zhong)rvvp屏(ping)蔽(bi)線(xian)運(yun)(yun)行(xing)(xing)(xing)(xing)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)易出(chu)現(xian)的(de)(de)故(gu)障主要分為(wei)(wei)(wei)絕緣(yuan)性(xing)問(wen)題(ti)(ti)和(he)(he)接頭(tou)問(wen)題(ti)(ti)。其中(zhong)(zhong)絕緣(yuan)性(xing)問(wen)題(ti)(ti)產生主要是(shi)由(you)(you)于(yu)rvvp屏(ping)蔽(bi)線(xian)的(de)(de)材(cai)料(liao)(liao)性(xing)質(zhi)和(he)(he)鋪設問(wen)題(ti)(ti)引起的(de)(de)。我國目(mu)前(qian)rvvp屏(ping)蔽(bi)線(xian)鋪設采用(yong)的(de)(de)主要的(de)(de)絕緣(yuan)材(cai)料(liao)(liao)為(wei)(wei)(wei)橡皮(pi)絕緣(yuan)材(cai)料(liao)(liao)、塑料(liao)(liao)絕緣(yuan)材(cai)料(liao)(liao)、氣體絕緣(yuan)材(cai)料(liao)(liao)以及油浸紙絕緣(yuan)材(cai)料(liao)(liao)。在鋪設的(de)(de)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)可能因(yin)為(wei)(wei)(wei)造型不當、制作不良(liang)或者(zhe)(zhe)使用(yong)的(de)(de)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)長期過(guo)(guo)(guo)載、靠近(jin)熱(re)源等多(duo)種原(yuan)因(yin)，導致(zhi)rvvp屏(ping)蔽(bi)線(xian)易受到(dao)化學腐蝕和(he)(he)受潮，導致(zhi)rvvp屏(ping)蔽(bi)線(xian)在運(yun)(yun)行(xing)(xing)(xing)(xing)的(de)(de)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)會時(shi)常出(chu)現(xian)絕緣(yuan)、老(lao)化或者(zhe)(zhe)受潮等問(wen)題(ti)(ti)，造成(cheng)rvvp屏(ping)蔽(bi)線(xian)故(gu)障。關于(yu)接頭(tou)問(wen)題(ti)(ti)主要是(shi)因(yin)為(wei)(wei)(wei)rvvp屏(ping)蔽(bi)線(xian)鋪設的(de)(de)密封(feng)失效、連(lian)接不良(liang)、封(feng)鉛漏(lou)水或者(zhe)(zhe)在運(yun)(yun)行(xing)(xing)(xing)(xing)過(guo)(guo)(guo)程(cheng)中(zhong)(zhong)長期過(guo)(guo)(guo)負(fu)荷運(yun)(yun)行(xing)(xing)(xing)(xing)等原(yuan)因(yin)造成(cheng)的(de)(de)。rvvp屏(ping)蔽(bi)線(xian)接頭(tou)的(de)(de)故(gu)障主要表現(xian)為(wei)(wei)(wei)rvvp屏(ping)蔽(bi)線(xian)的(de)(de)終端頭(tou)或者(zhe)(zhe)中(zhong)(zhong)間接頭(tou)處(chu)發生爆炸。

為了減少火(huo)災事故(gu)中rvvp屏蔽線(xian)接(jie)(jie)頭的故(gu)障(zhang)率(lv)，在安(an)裝過程(cheng)中應盡可能減少接(jie)(jie)頭的數(shu)量，以(yi)確保rvvp屏蔽線(xian)在火(huo)災中能正常工作。如果需要分支接(jie)(jie)線(xian)，則必須對(dui)接(jie)(jie)頭做好防(fang)火(huo)處(chu)理。
