Description

Technical Field

[0001] The invention belongs to the technical field of electric power maintenance devices, and in particular relates to a bypass down-lead cable load transfer device. Background Art

[0002] Line maintenance refers to the work carried out on the power transmission line based on the problems found in the inspection, inspection and test, aiming to eliminate defects, improve the health level of equipment, prevent accidents and ensure the safe operation of the line. It is a key task in the power industry and is essential to ensure the stable operation of the power system. In order to improve the safe operation performance of the line, increase the transmission capacity of the line and improve working conditions, it is necessary to improve or dismantle the line for maintenance work, such as replacing it with a large-section conductor, adding lightning arresters, increasing the number of insulators or replacing ordinary insulators with pollution-resistant insulators, replacing wooden poles with reinforced concrete poles (referred to as concrete poles) or iron towers, etc. The operation and maintenance unit should determine the planned maintenance items for the next year based on the health status of the line equipment, the inspection and inspection results, the maintenance cycle and the requirements of the anti-accident measures, prepare and report the annual maintenance plan, and implement it after approval by the superior production management department. The bypass downlead cable is an important equipment used in the non-stop operation of the distribution network. It can transfer the load by building a bypass loop without reducing the load, thereby ensuring that the power supply is not interrupted during the maintenance process. This cable usually has high flexibility and durability and can adapt to various complex operating environments. In the non-stop operation of the distribution network, the bypass down-lead cable is often used in scenarios such as replacing heating wire clamps with load and replacing pole-mounted disconnectors. It can also be used in conjunction with bypass load switches and other equipment to build a bypass loop to replace overhead lines and equipment with load. During the connection operation, due to the heavy weight of the bypass down-lead cable, if there is no external force intervention when connecting to the cable, there are safety hazards at the joint due to the large force.
