摘要
液压弹簧操动机构是高压断路器的重要组成部分,决定了断路器的分合速度和工作稳定性,而缓冲结构在操动机构动作过程中起着不可或缺的作用。为研究和优化800 kV超高压断路器的缓冲结构,对其进行理论分析,利用SolidWorks和ADAMS软件建立内阶梯形缓冲结构的数学模型,建立基于AMESim和ADAMS软件的联合仿真模型,并对分闸缓冲进行试验测试。通过仿真分析和试验研究,得到缓冲结构的动态缓冲油压及流体特性,对五级阶梯形缓冲结构进行优化改进,进一步提高了液压弹簧操动机构的可靠性和适用性。
A hydraulic spring mechanism is an important part of high voltage circuit breaker,and it determines the circuit breaker speed and stability of the work.The buffer structure plays an integral role in the movement of actuator.The theoretical analysis of buffer structure is made to research and optimize the buffer structure of 800 kV extra-high voltage circuit breaker.A mathematical model of step-type buffer structure is simulated by SolidWorks and ADAMS.A co-simulation model based on AMESim and ADAMS is established and a test of break-brake buffer is carried out.The dynamic buffer oil pressure and the fluid characteristics of the buffer structure are studied by experimental methods and simulation modeling.We improve reliability and applicability of hydraulic spring actuator by optimizing the five-stage step-type buffer structure.
