Description

Technical Field

[0001] The present invention relates to the technical field of live-line working on distribution networks, and in particular to a live-line working conductor bearing and fixing device for distribution networks and a use method thereof. Background Art

[0002] With the continuous development and progress of society, the scale of distribution network construction is also expanding, and the workload of distribution network operation and maintenance is increasing. During the live operation of the distribution network, insulators, transformers, line fittings, etc. are often damaged and need to be replaced. They need to be replaced with tension insulators. Strain insulators can not only withstand the tension of the wires, but also have the function of isolating conductors and brackets, and can withstand harsh environments such as wind, rain, and ice.

[0003] At present, when performing live operations on the distribution network, the line needs to be lifted. The method of lifting the conductor in the prior art requires the cooperation of two insulating boom trucks. One insulating boom truck uses an insulating small crane to lift the live conductor from above the line, and the other insulating boom truck transports the workers to insulators, transformers, line hardware, etc. to perform live operations, or the workers climb to the top of the pole and use the insulating support rod method to lift the conductor. The first method wastes work costs, and the operation method using the insulating support rod has a large conductor weight and is more laborious to lift. In addition, the automation level is low, the labor intensity is high, and the efficiency is low. In addition, the operator directly contacts the high-voltage conductor, which is easy to cause electric shock accidents, posing a great safety hazard.
