Double-loop same-tower power transmission line electric field inlet and outlet device and method

The invention provides a double-loop same-tower power transmission line electric field inlet and outlet device and method. The device comprises an escalator, a first control rope and a second controlrope. The escalator is fixed on one end of a cross arm away from the tower body through two groups of connection components, and a flexible escalator is connected on the lower end of the escalator. One end of the first control rope is connected at the connection part between the cross arm and the escalator, and the other end is used for connecting the safety strap of the operator. One end of the second control rope is connected on the position of the cross arm exactly above a lead, and the other end is used for connecting the safety strap of the operator and the length of the second control rope is equal to the vertical distance between the cross arm and the lead. According to the double-loop same-tower power transmission line electric field inlet and outlet device and method, the problemsof complicated process of
