输电线路砼杆接地引下线专用连接螺栓的研制

Research on Special Connecting Bolt for Ground Down Lead in Power Transmission Line Reinforced Concrete Pole

为解决输电线路砼杆接地引下线使用普通螺栓连接在运行中存在连接不可靠的问题,通过运行实例分析了普通螺栓的不足之处,根据电阻与接触面的关系理论,设计了一种新的专用连接螺栓。实际运用情况表明:该螺栓能成功地解决砼杆接地引下线在运行中与杆内接地引线连接不可靠的问题,有效地保证了输电线路的安全运行。

In order to solve the unreliability problem in connecting caused by the use of ordinary bolt in ground down lead of power transmission line reinforced concrete pole, the deficiencies of the ordinary bolt are analyzed through typical examples, then one kind of new connecting bolt is designed specially according to the theory of the relation between resistance and contact face. The actual indicates that the above problem can be solved successfully by using new bolt, and the capabilities of lightning protection and resistance reducing are enhanced greatly, which is the guarantee of the safety in power transmission line.
