Problems solved by technology

Due to the use of integral spacers on the split wires, in some cases, it is more likely to cause resonance and galloping, and the external conditions greatly increase the possibility of galloping; in addition, setting a suspension weight is also a way to reduce galloping , but the cost performance is too low, and a large mass is needed to reduce the galloping of a small part of the transmission line; secondly, a few researchers have developed a nonlinear passive control device, which can effectively reduce the vibration of the transmission line, but lacks self-regulation function, and the vibration suppression range is limited , if the power line moves too much, the device will not work properly

Abstract

The invention discloses a semi-active anti-dancing damping control device, comprising a connecting part, a limiting part and a control part. The connecting part is located at two ends of the whole device, respectively connected with an outward rigid bar of the limiting part and the control part and used for connecting with a transmission line spacer bar. The limiting part takes the hollow body surrounded by the periphery as the main body, is connected with an azimuth spacer rod through a rigid connecting rod, and drives four cylindrical cylinders to move through a partition plate; The controlsection is connected to a spacer rod in another orientation through a rigid connecting rod, and comprises an incompletely closed housing, four separate oil chambers and elastomers, a central cylinder,and an induction controller.

Description

technical field [0001] The invention belongs to the field of anti-galling control of transmission lines in transmission line engineering, and in particular relates to a semi-active anti-galling and vibration reduction control device, which is mainly used to control the galloping phenomenon of transmission lines under the action of wind load. technical background [0002] According to the national grid plan, "three longitudinal lines, three latitude and longitude lines and one circular line" will be built by 2020, and the importance of transmission lines as lifeline projects is becoming increasingly significant. With the development of the economy and society, the power load is increasing day by day, and the situation of the power grid facing the peak and overwintering is becoming more and more severe. Therefore, starting the research on anti-galling technology of high-voltage transmission line conductors has become one of the key problems that need to be solved urgently for t...
