10kV/20kV电缆测温系统

在10kV/20kV的(de)电(dian)(dian)缆(lan)配网中,电(dian)(dian)缆(lan)终端头与电(dian)(dian)缆(lan)本体相比,是薄(bo)弱(ruo)环节(jie),是电(dian)(dian)缆(lan)线路安(an)全运行(xing)的(de)短板。实际运行(xing)中电(dian)(dian)缆(lan)头发生故(gu)障前,往(wang)往(wang)有(you)出现发热,加速绝缘老化,最后造成击穿短路“放炮”的(de)过程。在此期间其(qi)电(dian)(dian)缆(lan)头温度会比正(zheng)常(chang)情况下(xia)高(gao)出许多,而且(qie)会持续相对较长的(de)一(yi)段时间,所以(yi)理论上是可以(yi)通(tong)过定期测量电(dian)(dian)缆(lan)终端温度及(ji)时发现可能存(cun)在的(de)缺陷情况。
