66kV线路钢管杆带电更换直线绝缘子所用杆头卡具
摘要：
本实用新型涉及66kV线路钢管杆带电更换直线绝缘子所用杆头卡具，它包括有承力上横梁、紧固下横梁、紧固螺栓和可调紧固螺栓，承力上横梁上开有螺孔和可调式长孔，承力上横梁的一端设置有U形槽，U形槽上连接有螺栓形成工具悬挂点，所述的紧固下横梁上设置有螺孔和可调式长孔，紧固螺栓和可调紧固螺栓分别穿过螺孔和可调式长孔将承力上横梁与紧固下横梁连接在一起。本实用新型可在带电线路上开展，提高了供电可靠性。适用所有单导线及复导线的钢管杆输电线路使用，提高了通用性。本实用新型安装在钢管杆横担头部的同时，也有效增加了带电导线对地距离、空气间隙、增强了绝缘工器具的绝缘系数及绝缘水平，提高了安全性。
摘要（英）：

The utility model relates to a rod head fixture for live change of a linear insulator on a steel pipe pole of a 66kV line, which comprises the components of: a force bearing upper crossbeam, a fastening lower crossbeam, a fastening bolt and an adjustable fastening bolt. The force bearing upper crossbeam is provided with a screw hole and an adjustable elongated hole. One end of the force bearing upper crossbeam is provided with a U-shaped tank which is connected with a bolt forming tool suspension point. The fastening lower crossbeam is provided with a screw hole and an adjustable elongated hole. The fastening bolt and the adjustable fastening bolt respectively penetrate through the screw holes and the adjustable elongated holes for connecting the force bearing upper crossbeam with the fastening lower crossbeam. The rod head fixture can be used on a live line and improves power supply reliability. The rod head fixture is suitable for use by all single-lead and multiple-lead steel pipe pole power transmission lines and improves versatility. When the rod head fixture is mounted on the cross arm head of the steel pipe pole, the rod head fixture performs the following functions: effectively enlarging a distance between a live lead and ground and an air gap, improving insulation coefficient and insulation level of an insulating tool, and improving safety.
