500kV power transmission line hot-line work rapid suspension device and operation method

Abstract

The invention discloses a 500kV power transmission line hot-line work rapid suspension device. A suspension point used for being connected with an unmanned aerial vehicle is arranged at the top end of the device, and the bottom end of the suspension point is connected with a suspension mechanism; the suspension mechanism comprises a connecting frame and a suspension main body; an elastic element is arranged on one side face of the opening and closing type suspension stretching rod, and the maximum stretching length is 100 mm; a suspension main body is arranged at the position, corresponding to the elastic element, of the other side face of the opening and closing type suspension stretching rod, the top end of the suspension main body is connected with an open hook used for being suspended on a wire, and the bottom end of the hook is connected with a pulley assembly. The connecting frame is arranged between the suspension point and the opening and closing type suspension stretching rod, or the connecting frame is arranged between the hook and the pulley assembly.

Description

technical field [0001] The invention belongs to the technical field of live work on high-voltage circuits, and in particular relates to a quick suspension device and an operation method for live work on 500kV transmission lines. Background technique [0002] The 500kV transmission line is the main grid for the transmission of electric energy. The transmission line is widely distributed. It is an important component of the power plant to transmit electric energy to the outside. A trip event occurs on the outbound transmission line of the station, which seriously leads to safety events that threaten the stable operation of the power grid, such as the DC unit lockout or the emergency shutdown of the nuclear power plant. The 500kV transmission line cannot be shut down for maintenance except for special reasons, and the live maintenance of the transmission line is an important maintenance method for the 500kV transmission line. [0003] The current live work methods and tools fo...

Problems solved by technology

[0002] The 500kV transmission line is the main grid for the transmission of electric energy. The transmission line is widely distributed. It is an important component of the power plant's external transmission of electric energy. A tripping event occurs on the outgoing transmission line of the station, which seriously leads to the blockage of the DC unit or the emergency shutdown of the nuclear power plant and other safety events that threaten the stable operation of the power grid.

[0003] The current live work methods and tools for transmission lines are relatively traditional and backward. The use of hanging ladders combined with elevators, in the traditional live work forms such as: spanning two short three methods, hanging ladder method and elevator method, the specific methods are mostly climbing poles and walking Lines and other links, the labor intensity of the operators is high, there are many operators on the tower, the operation time is long, and the safety risk is high, which is not conducive to extensively carrying out live work on multiple transmission lines
