摘要
本文针对供电线路中 ,当系统发生短路故障时 ,会产生较高的纵向感应电势 ,引起纵差保护装置误动 ,甚至电缆绝缘击穿这一现象 ,提出了抑制电磁干扰的对策 ,并由此设计研制了导引电缆。
A higher level of longitudinally induced potential may occur when the power line is short circuited,which may cause error action of the longitudinal difference protection and even breakdown of cable insulation. This paper presents a counter measure to prohibit EMI, upon which the pilot cable is designed.
