针对特高压断路器管道系统中产生的液压冲击波对操动系统运行的影响，以蓄能器及其管道系统作为研究对象，在分析其压力波动产生机理的基础上，确立了管道子模型的选取原则，应用AMES-im软件建立了液压系统的综合仿真模型，对模型进行求解后得到了液压管道的压力波动特性，同时分析了管道长度和内径对压力波动幅度的影响。研究结果表明：现有管道系统的压力波动幅度较大，不利于系统的稳定运行；对管道长度和内径组合进行优化设计后，压力波动的降幅在50%以上。所采用的研究方法对特高压断路器管道系统的优化设计具有参考价值。

With the purpose of settling the impact of hydraulic shock in hydraulic operating system of UHV breaker,energy accumulator and its hydraulic pipeline system served as the research objects. Based on the analysis of pressure fluctuation mechanism,principles of selecting sub-model of pipeline were established.With the simulation of comprehensive model of the hydraulic system using software AMESim,characteristics of pressure fluctuation in the hydraulic pipeline was obtained.Meanwhile, impacts of length and diameter of pipeline on pressure fluctuation were analyzed.The results show that the existing pressure fluctuation amplitude is large,which is not conducive to the stable operation of the system.After combinatorial optimization of length and diameter of pipeline,pressure fluctua-tion is reduced by over 50%.The adopted research methods have certain theoretical guidance and practical value to optimal design of pipeline system in UHV breaker.
