摘要
铠装屏蔽二次电缆在变电站中的使用日益广泛,但其接地线制作工艺不良会造成电缆发热、爆燃。因此,基于现场变电二次系统的运维检修经验,提出一种变电站用铠装屏蔽二次电缆接地线制作的“备、剥、接、核”四步操作法,并通过实践验证了该方法的有效性与可行性。
Armored shielded secondary cables have been increasingly applied in substations,but the poor techniques for making such grounding wires would cause cable heating and even deflagration.Therefore,based on the maintenance and overhaul experience of such secondary systems in a substation,a four-step operation approach of"prepare,strip,connect and check"for making armored shielded secondary cable grounding wires for substations is proposed and the approach is verified effective and feasible in the field practice of substations.
