Multi-split conductor bundle deicing and overturning prevention device

Abstract

The invention provides a multi-split conductor deicing and overturning prevention device which comprises a spacer, a swing rod and a balancing weight. The spacer is clamped on the multi-split conductor bundle and is provided with a central shaft; the upper end of the swing rod enters the spacer and is hinged with the central shaft of the spacer, and the lower end of the swing rod is connected withthe balancing weight, so that the problems of static twisting and torsional vibration of the multi-split conductor caused by uneven ice coating and asynchronous deicing of the sub-conductors are solved, the vibration time is shortened, the vibration can be stopped quickly, and the damage to the sub-conductors, the sub-conductor spacer and the inter-phase spacer is avoided. The multi-split conductor deicing and overturning prevention device has simple structure, the deicing and overturning phenomena of the multi-split conductor can be well prevented and treated, and the condition that the sub-conductors and the spacer are damaged due to deicing and overturning of the multi-split conductor is avoided; and the multi-split conductor deicing and overturning prevention device is convenient to install, high in reliability, adjustable in rigidity of the spring, weight of the balancing weight and distance between the upper edge of the balancing weight and the lower edge of the middle frame ofthe spacer, and wide in range of application.

Description

technical field [0001] The invention relates to the technical field of overhead power transmission lines, in particular to a device for preventing deicing and overturning of multi-split wire bundles. Background technique [0002] Transmission lines running across cold regions or in winter are prone to ice coating under suitable weather conditions. When the ambient temperature rises or the combined action of wind force and ice coating gravity, the ice coating will fall off from the ground wire, causing the ice load to increase. Suddenly unloading, resulting in a large vibration jump of the wire, this phenomenon is called deicing jump. De-icing jumps may lead to electrical accidents such as short circuits or flashovers, and mechanical damage accidents such as broken strands and broken wires, hardware and tower component damage, especially for multi-split wire bundles. It will cause static torsion of the multi-split wire bundle, and asynchronous deicing of the sub-wires may ca...
