Problems solved by technology
However, due to the increasing requirements of users on the reliability of power supply, power outages are difficult, and in the case of a large number of broken strands of overhead ground wires, due to the limited load capacity, disconnection accidents are very easy to occur, resulting in casualties and equipment damage. Serious consequences, so there have always been some difficulties in the maintenance of overhead ground wires

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with specific embodiments of the present invention and accompanying drawings.
[0016] Such as Figure 1-Figure 3 As shown, the appearance of the 220kv Li-Xu line overhead ground wire maintenance board ladder of the present invention is similar to the structure of the common board ladder. The board ladder 2 is made of insulating material, and each ladder section of the board ladder 2 is a circular insulating rod structure. The upper end of the board ladder 2 is provided with two pulleys 1, the pulleys 1 are provided with a locking device, so that the range of movement of the board ladder is not limited, and the board ladder can also be fixed by the locking device, and the two ends of the lower part of the board ladder are respectively provided with three The wire clamping groove 3, the wire clamping groove 3 can adjust the length and position according to the distance between the overhead ground wire...

The invention relates to a live maintenance overhead ground wire device, in particular to a 220kv Li-Xu line overhead ground wire inspection board ladder. It is a board ladder for overhauling overhead ground wires under the condition of ensuring that the line is not powered off and the safety of personnel and equipment is ensured. In the present invention, the two ends of the upper part of the board ladder are provided with pulleys respectively, and the two ends of the lower part of the board ladder are respectively provided with wire clamping grooves, and the lower end of the board ladder is connected with the soft ladder. Compared with the existing technology, the maintenance of overhead ground wires can be carried out through live work or equipotential work under the normal operation of the 220kv Li-Xu line, and part of the overhead ground wire load can be transferred to ensure the safety of personnel and equipment. It can not only greatly improve the reliability of power supply, but also ensure the safety of personal and equipment. Due to the use of pulleys as the moving medium, it has the characteristics of flexibility and is not limited by the point of failure. It also has the advantages of simple production of materials and utensils, easy portability, small investment, high safety, etc., and can be popularized and applied.
Description
technical field [0001] The invention relates to a live maintenance overhead ground wire device, in particular to a 220kv Li-Xu line overhead ground wire inspection board ladder. It is a board ladder for overhauling overhead ground wires under the condition of ensuring that the line is not powered off and the safety of personnel and equipment is ensured. Background technique [0002] At present, the maintenance work of the known overhead ground wires of transmission lines should be carried out in the case of power failure. Generally, a movable common board ladder is used. The top of the board ladder generally adopts two pulleys, which can slide freely on the wire, and the operation range is not limited. Use the soft ladder or directly enter the board ladder from the pole tower to repair the damaged part of the overhead ground wire. However, due to the increasing requirements of users on the reliability of power supply, power outages are difficult, and in the case of a large ...
