Abstract

The spacer keeps a certain distance between the split sub-conductor to prevent the split sub-conductors from whipping each other. In addition, the spacer has a certain effect on suppressing the aeolian vibration of the transmission line. In recent years, due to improper design and selection of spacer, damage to the spacer and faults of worn wires have occurred from time to time. It is necessary to study the vibration characteristics and damping performance of the spacer in the anti-vibration design of the transmission lines. The mechanism of typical structural damper spacers to suppress the aeolian vibration is analyzed, and the mathematical model of aeolian vibration of the damper spacers for multi-split conductors is established. The stiffness-damping method and damping method are used to carry out experimental research on the damping characteristics of the spacer. The key parameters that characterize the vibration characteristics of damper spacer are presented, which provides a reference for the design of spacer.

阻尼垫片风成振动模型及阻尼特性试验研究

隔离器在分裂子导体之间保持一定的距离，以防止分裂子导体相互鞭打。此外，隔震器对抑制传输线的风振也有一定的作用。近年来，由于垫片的设计和选用不当，导致垫片损坏和钢丝磨损故障时有发生。在输电线路的减振设计中，有必要对隔震器的振动特性和阻尼性能进行研究。分析了典型结构阻尼垫片抑制风成振动的机理，建立了多分路导体阻尼垫片风成振动的数学模型。采用刚度-阻尼法和阻尼法对隔震器的阻尼特性进行了实验研究。给出了表征隔振器振动特性的关键参数，为隔振器的设计提供了参考。
