Connection system for tower and ground wires

一种杆塔地线连接系统

Abstract

本实用新型公开了一种杆塔地线连接系统,包括杆塔、设置在杆塔顶端两侧的普通地线和光纤复合架空地线,所述光纤复合架空地线通过地线绝缘子串固定在杆塔的一侧,光纤复合架空地线的连接处与耐张线夹相连接,耐张线夹固定在杆塔上。采用上述结构,由于光纤复合架空地线是通过地线绝缘子串固定在杆塔上,这样光纤复合架空地线就被地线绝缘子串分段绝缘了,只在相邻两盘光纤复合架空地线相连处通过耐张线夹与杆塔接地,从而改变了传统的光纤复合绝缘子逐塔接地的方式,这样光纤复合绝缘子也是分段绝缘,一点接地,减少地线环流的产生,大幅度降低了损耗,降低了电力生产的成本。
The utility model discloses a connection system for a transmission tower and ground wires. The system comprises the transmission tower, as well as an ordinary ground wire and a composite fiber-optic overhead ground wire which are arranged on two sides at the top end of the tower, the composite fiber-optic overhead ground wire is fixed on one side of the tower through a ground wire insulator string, the connection part of the composite fiber-optic overhead ground wire is connected with a strain wire clamp, and the strain wire clamp is fixed on the tower. The construction of the utility model involves fixing the composite fiber-optic overhead ground wire onto the tower through the ground wire insulator string, and in doing so the composite fiber-optic overhead ground wire is insulated segment by segment through the ground wire insulator string and is only grounded at the connection part of two neighboring composite fiber-optic overhead ground wire coils, together with the tower through the strain wire clamp. The utility model can also apply to a fiber-optic composite insulator which can be insulated segment by segment and grounded at one point, rather than being subject to the traditional method, e.g. being grounded tower by tower. The utility model has the advantages of reducing the occurrence of circumfluence arising in the ground wires, greatly reducing loss, and curtailing the cost of electrical production.
