电力系统中一种大截面高压电缆锯断前的确认检测法

A Method of Verification before Sawing a Large Section of High Voltage Cable in Power Systems

电力系统中大截面电缆锯断前的确认检测一直是一个非常棘手的难题。近年来随着太钢新炼钢、新热轧、新高炉等大规模生产线的不断投运,供电系统的供电电压等级、供电容量也在不断地扩大,系统电缆已逐步更换为10 kV、35 kV、110 kV的大截面电缆,使得这一难题更加突出。就此棘手难题提出了技术改进构思,并阐述了技术改进方案及实施后的效果。

It is always a very difficult problem to confirm and detect the large section cable before sawing.In recent years,with the continuous put into operation of large-scale production lines such as new steelmaking,new hot rolling and new blast furnace in TISCO,the power supply system’s power supply voltage grade and power supply capacity are also constantly expanded.The cables of system has been gradually replaced with large-section cables of 10 kV,35 kV and 110 kV,which makes this problem more prominent.This paper puts forward the idea of technical improvement,and expounds the technical improvement scheme and the effect after implementation.
