摘　　要：随着电力系统的发展,高压输电的电压等级逐渐升高。均压环的应用也日趋广泛。由风振引起的均压环振颤问题始终是影响输电安全不容忽视的因素。本文采用加装破坏共振的阻尼棒系统解决了750kV变电站绝缘子均压环振颤的问题,为该类设备技术改造提供了新的思路。With the development of the electric power system, the voltage grade of the high voltage electric power transmission is gradually going up. The application of the grading rings become widely. The grading rings vibration caused by fitful wind always influence the security of the electric power transmission. This paper using damping system solves insluator grading rings vibration, provides new idea for the design and manufacture.
