Abstract

The invention discloses a multi-level composite energy-consuming anti-dancing moving spacer bar. The multi-level composite energy-consuming anti-dancing moving spacer bar includes a spacer bar body and a clamping fixture used for connecting split wires, wherein the spacer bar body includes an annular tube, a partition and a mass ball are arranged inside the annular tube, an inner ring of the annular tube is connected with upper and lower annular permanent magnets, a movable cylinder is arranged on an inner side, an outer ring of the movable cylinder is connected with a conductor plate, the conductor plate extends into a passage between the upper and lower permanent magnets, the movable cylinder and the annular tube are connected by a spring and a roller, and a drum equipped with the damping fluid is arranged in the movable cylinder.

Description

technical field [0001] The invention belongs to the field of power transmission line engineering, and in particular relates to a multi-stage composite energy-consuming anti-galling spacer, which is mainly used for controlling galloping of split conductors in power transmission lines under wind load. Background technique [0002] As an important lifeline project, the transmission tower-line system is closely related to people's normal life. With the development of society and economy, the requirements for the transmission tower-line system are increasing day by day. Due to the characteristics of high flexibility and large span of the transmission tower-line system, it is very susceptible to the effects of wind loads, among which galloping of the transmission conductor is a common phenomenon, that is, the conductor is excited by uneven ice coating and lateral wind. The low-frequency, large-amplitude self-excited vibration phenomenon that occurs in the wire. [0003] The space...
