【摘要】 目前国内基于试验设备的情况和试验条件的限制,对于110kV交联电缆的耐压试验多数还是采用直流192kV、15分钟作为标准,IEC60840则对于交联电缆的耐压试验推荐采用交流系统最高运行电压、5分钟作为试验标准。110kV三蕉线前后两次分别采用了直流、交流作了试验,根据两次试验的结果,结合国内外形势发展趋势,有必要制订本行业关于110kV交联电缆(XLPE)竣工试验的标准。更多还原

【Abstract】 Limited by the test equipments and test conditions, DC 192kV/15minutes is still adopted as a standard for withstand voltage test of 110kV XLPE cable at home now. However according to IEC60840 this standard is recommended to be the max operation voltage of AC system/5minutes. DC test & AC test have been done separately in Sanjiao power cable line. According with the test results and combining the development trend inside and outside state, the author points out it is very need for the power supply industry to draw a commission test standard of 110kV XLPE cable.更多还原
