       如(ru)何(he)维护管型母线?
   1,应(ying)用开关(guan)电源部(bu)件的维(wei)护保养来清除系统总线(xian)故(gu)障(zhang)。
   针对不太关键的配(pei)电(dian)(dian)站(zhan),能够 应(ying)用(yong)第二(er)级维(wei)护(hu)保养的开(kai)关电(dian)(dian)源(yuan)部件(比(bi)如变电(dian)(dian)器)来(lai)清除管状(zhuang)系统总线故障。

   2,独特(te)的管(guan)状(zhuang)客(ke)车检修(xiu)。在下列(lie)状(zhuang)况下,应出示独特(te)的管(guan)状(zhuang)客(ke)车检修(xiu):
  (1)为保证 有选择拆卸(xie)110 kV及之上的(de)多管(guan)母线(xian)(xian)和按段式单管(guan)母线(xian)(xian)的(de)一(yi)切一(yi)部分,无故障时,管(guan)母线(xian)(xian)的(de)另(ling)一(yi)部分仍可(ke)再(zai)次运作(zuo)。应出示独特的(de)管(guan)状客车检修。
  (2)针对110 kV及之(zhi)上(shang)的(de)单管母(mu)线,髙压(ya)侧为110 kV及之(zhi)上(shang)的(de)关键降血压(ya)配电站的(de)35 kV列管式母(mu)线。依(yi)据规定(ding),对机(ji)器(qi)设备(bei)的(de)全部迅速(su)维护(hu)保养务必在安裝机(ji)器(qi)设备(bei)以(yi)前(qian)快速(su)清除管系统(tong)总(zong)线上(shang)的(de)缺点。
  (3)当管状母线产生短路故(gu)(gu)障(zhang)(zhang)(zhang)故(gu)(gu)障(zhang)(zhang)(zhang)(故(gu)(gu)障(zhang)(zhang)(zhang)在隔离(li)开关(guan)(guan)和电压互感器(qi)中间)或隔离(li)开关(guan)(guan)有(you)故(gu)(gu)障(zhang)(zhang)(zhang)时,假如(ru)路线配置了一些高频率(lv)维护保(bao)养(yang),则管状母线维护保(bao)养(yang)应终止髙(gao)压故(gu)(gu)障(zhang)(zhang)(zhang)。侧(ce)的高频率(lv)信号发射器(qi),并使相对性的高频率(lv)维护保(bao)养(yang)机器(qi)设(she)备跳离(li)隔离(li)开关(guan)(guan)。

  (4)当关键配(pei)电站的(de)管状(zhuang)(zhuang)母线(xian)产生(sheng)故(gu)障时,为(wei)防止隔离开关与故(gu)障的(de)管状(zhuang)(zhuang)母线(xian)重合,应(ying)在(zai)管状(zhuang)(zhuang)母线(xian)检(jian)修后明(ming)确路线(xian)重合闸。
  (5)为了(le)更好地使管状母线(xian)产生短路故(gu)(gu)障(zhang)(zhang)故(gu)(gu)障(zhang)(zhang),隔(ge)离开(kai)关故(gu)(gu)障(zhang)(zhang)或隔(ge)离开(kai)关与电压互感器(qi)中间存(cun)有故(gu)(gu)障(zhang)(zhang)。故(gu)(gu)障(zhang)(zhang)维护保养(yang)能够(gou) 靠谱地清除故(gu)(gu)障(zhang)(zhang)。当开(kai)展管状系统总(zong)线(xian)维护保养(yang)时,应逐(zhu)渐故(gu)(gu)障(zhang)(zhang)维护保养(yang)。
  (6)在500kV配电(dian)(dian)(dian)站中,当225kV侧管状(zhuang)母(mu)线(xian)(xian)(xian)跳(tiao)电(dian)(dian)(dian),变(bian)电(dian)(dian)(dian)器隔离(li)开(kai)关失效(xiao)(xiao)或(huo)225kV侧变(bian)电(dian)(dian)(dian)器隔离(li)开(kai)关失效(xiao)(xiao)时,相(xiang)对应的(de)管状(zhuang)母(mu)线(xian)(xian)(xian)应跳(tiao)电(dian)(dian)(dian)。这(zhei)时,管状(zhuang)母(mu)线(xian)(xian)(xian)的(de)维(wei)护保养姿势应逐(zhu)渐(jian)另一(yi)侧的(de)变(bian)电(dian)(dian)(dian)器的(de)维(wei)护保养行程(cheng)安排(pai)。
  (7)当变(bian)电(dian)(dian)器(qi)中产生(sheng)底压侧(ce)故(gu)障时,管(guan)母(mu)线(xian)(xian)侧(ce)隔(ge)离开关(guan)(guan)跳(tiao)电(dian)(dian),隔(ge)离开关(guan)(guan)故(gu)障,变(bian)电(dian)(dian)器(qi)维护保养(yang)设备消除管(guan)母(mu)线(xian)(xian)故(gu)障复合型工(gong)作电(dian)(dian)压锁住。
