摘要:
根据对不同金属屏蔽层接地方式、不同敷设排列方式情况下的电缆金属屏蔽层感应电压及环流的计算，分析各种影响因素对环流值大小的影响，结合湖北地区110 kV及以上高压电力电缆运行现状，给出金属屏蔽层环流控制标准的参考值。
Based on calculations of induced voltage and circulation of metal shield layer in cable, regarding different grounding modes and different arrangement, the influence of various factors on circulation is investigated. The reference values of circulation control standard in metal shield layer are given, according to operation status of high voltage power cables of 110 kV or above in Hubei province.
