Problems solved by technology
One is that the scope of work is limited. When the terrain of the distribution line is uneven or there are many buildings around, the insulated arm truck cannot approach the working position, so the insulated arm truck cannot be used for operation
The insulating platform method is adopted, and the insulating platform is manually installed by electric workers. Due to the heavy weight of the insulating platform, it still needs multiple people to carry it in areas where the terrain is rough and cannot be reached by transport vehicles, and the operation is time-consuming and laborious.
[0006] Therefore, there is an urgent need to develop a special tool and method for the operator to use the foot buckle to climb the pole to complete the live installation of the ground potential operation method and replace the bird-repelling windmill, so as to overcome the time-consuming and labor-intensive problems that the insulated bucket truck cannot reach or the work of multiple people is time-consuming and laborious. , to ensure the safety of installing and replacing bird repelling windmills, and improve operating efficiency

The invention discloses a dedicated tool and method for replacing a bird repelling windmill with the power on by a ground potential working method. The dedicated tool comprises a main body alloy plate (1) in a shape as shown in the description, a fastening bolt (3) and the like. A connecting rod (4-2) of a bird repelling windmill (4) can be embedded into a U-shaped clamping groove (1-5) of the main body alloy plate (1) of the dedicated tool. A [-shaped fixing seat (4-3) of the bird repelling windmill (4) is placed in the main body alloy plate (1) in the shape as shown in the description of the dedicated tool. By connection of an insulated operating rod with a sleeve to the fastening bolt (3) of the dedicated tool or a windmill fastening bolt (5) and fastening, the fixation between the dedicated tool and the bird repelling windmill (4) or between the bird repelling windmill (4) and a power distribution lines cross arm (6) is realized to achieve the replacement of the bird repelling windmill. The dedicated tool and method in the invention have the advantages of simple structure, convenient use, safe operation, wide range of application, high mechanical strength, low manufacturing cost and high operation efficiency.
Description
Technical field: [0001] The invention relates to a special tool and method for live replacement of a bird-repelling windmill by the ground potential operation method, which is widely used in live installation and replacement of a bird-repellent windmill by the ground potential operation method in a 10kV power distribution line of a power system, and belongs to the live maintenance site of a power distribution line technology field. Background technique: [0002] In recent years, with the enhancement of people's awareness of environmental protection and the continuous improvement of the ecological environment, the population, number and range of activities of birds living in nature have gradually increased, and birds nest on the line towers. In the statistics of power line accidents in recent years, accidents such as trips caused by birds not only gradually increased, but also showed a rapid upward trend, which had a great impact on the safe operation of the power grid. This...
