一种可伸缩多转向线路接地线的研制与应用

The Development and Application of a Scalable and Multiple Steering Grounding Wire

目前上海地区使用的10 kV线路接地线存在不足之处,介绍了一种新型10 kV线路接地线的研制过程和实际试用结果。指出该接地线通过伸缩方式改变绝缘杆的长度,可满足较大距离下挂接接地线的需求;同时还能通过调整接地头的角度,将接地线挂接在引线桩头等部位上,避免了电力作业人员挂接接地线时距离带电部位过近的情况,从而保证作业安全。

This paper introduces a new 10 kV line grounding wire with scalable insulating rods and multiple steering joints.The new grounding wire changes the length of the insulating rods by telescopic means,which can meet the requirements of connecting the grounding wire at a large distance.At the same time,the grounding wire can be attached to the lead pile head and the like by adjusting the angle of the joint.The trial effect shows that the grounding wire can effectively prevent the electric power operator from being too close to the live part when the grounding wire is hooked,thereby ensuring the safety of the operation.And it can be conveniently attached to the lead pile head,thereby reducing the work intensity and improving the operation effectiveness.
