摘要
Abstract
With the transformation and upgrading of the distribution network,the proportion of cable lines in the power supply network of Longkou Coal and Electricity Co.,Ltd.is increasing year by year.In view of the problem of limitations of terrain and other conditions during the process of cable laying,which can easily cause damage to the outer protective layers,especially for single-core cables,the outer sheath is prone to form a grounding loop after being damaged,generating grounding circulation current,causing the metal steel armor of the cable to heat up,reducing the cable transmission capacity,and affecting the normal power distribution of the cable line.Using the principles of step voltage and DC current,by comparing the data changes law between simulated faults and actual faults,the cable protective layer faults searching method and graphic data analysis are recorded in detail,providing theoretical basis and practical experience for cable protective layer faults searching,and quickly locating the fault point.关键词
