摘要

文中采用建模和仿真方法对安装于某水电厂的某一带气动操动机构的330 kV GIS断路器分、合闸操作异常振动问题展开研究。首先

建立了带气动操动机构断路器的运动模型

仿真分析了其操作时的振动特性及气动机构工作气压变化对振动特性的影响。然后

又对带液压操动机构断路器操作时的振动特性展开了建模和仿真分析。部分仿真结果也与试验结果进行了对比

能够较好吻合。通过对带两种不同操动机构断路器振动特性仿真结果的对比发现:液压操动机构断路器的振动强度比气动机构的要小

而且液压机构断路器振动强度的衰减速度更快

说明液压机构相比于气动机构更有利于减振。最后

还通过仿真分析了该断路器的安装基础结构对振动特性的影响

发现该水电厂大跨度的钢筋混凝土楼板结构是异常振动的重要诱因。

Abstract

Modeling and simulation methods are employed to analyze the switching induced abnormal vibration of the 330 kV GIS circuit breaker（CB） with pneumatic actuator in a hydro power plant. Firstly

a motion model of the CB with pneumatic actuator is established to simulate its vibration characteristic in action and the effect of working pressure of the pneumatic actuator on the vibration. Then

the vibration characteristic of the CB with hydraulic actuator in action is also modeled and simulated. Some simulation results are compared with the experimental ones

and they agree well with each other. Comparison of the simulation results between the CBs with respective hydraulic and pneumatic actuators indicates that hydraulic actuator leads to lower vibration strength and faster vibration strength attenuation of CB than pneumatic actuator

which implies hydraulic actuator is more favorable for reducing the vibration. In addition

the effect of foundation of CB on vibration characteristic is simulated and it is found that the long-span steel concrete structure is an important incentive of the abnormal vibration.
