Description

Technical Field

[0001] The invention belongs to the technical field of insulator strings, and particularly relates to an installation auxiliary fitting for a four-circuit strain insulator string. Background Art

[0002] A conductor strain string is a group of insulator strings with all fittings and accessories, which bears the tension of a conductor or bundled conductors. Electric power fittings on a long-term operating transmission line have to withstand the severe tests of ice, snow, and storms. Strong winds, freezing rain, and ice coating are likely to cause faults such as conductor de-icing jumps, phase-to-phase short circuits, and conductors colliding with lightning conductors. Therefore, electric power fittings must have high mechanical strength and sufficient safety factors; a suspension string is an important fitting in a transmission line, which bears the weight of the conductor in the vertical direction, the weight of ice coating, and the wind force in the horizontal direction. The existing suspension strings have the following problems: First, the existing strain strings cannot meet multi-bundle requirements; second, due to the significant increase in the self-weight of the conductor, ice coating, and wind force in the horizontal direction, the existing strain strings can no longer meet the strength and stability requirements of the transmission line, and the reliability of the connection will also be affected when the conductor vibrates. Therefore, the overall reliability of the suspension string is not high, and its structure needs to be optimized; Therefore, it is very necessary to provide an installation auxiliary fitting for a four-circuit strain insulator string with reasonable structure, convenient use, realizing multi-bundle installation, and ensuring the safe and reliable operation of the line.
