摘　　要：本文根据高压电缆交叉互联系统中护层电流异常时不能准确反映绝缘状况的现状,提出了电缆智能互联系统和新的护层电流监测的设计思路,并设计了由切换模块和时序控制模块组成的智能互联箱,在此基础上构建智能互联系统实现对每段每相护层电流的监测,为电缆监测和检修带来便利。According to the cross link high voltage cable system abnormal protection layer current can not accurately reflect the status of the insulation condition,a design of the cable intelligent interconnection system and a new protection layer current monitoring are put forward,an intelligent interconnected box composed of switching module and time series control module is designed.On this basis,the intelligent interconnection system is constructed to monitor protection layer current in each phase of each section,make the cable monitoring and maintenance convenient.
