摘要
SF6高压断路器是输变电系统中关键的控制和保护设备,主要由灭弧室与操动机构两个重要部分组成,操动机构驱动灭弧室进行开合操作。为获得二者间的动力学特性,以压气式SF6断路器为研究对象,依据能量守恒定律建立了灭弧室与弹簧操动机构的动力学数学模型。通过研究压气室压力与缓冲阻力的数学模型,并运用ADAMS与Matlab联合仿真建立了断路器虚拟样机模型,实现了断路器行程曲线的仿真计算、零部件的动态受力分析及结构优化设计,通过与断路器实测机械行程曲线的对比,证明了仿真方法的准确性。
SF6 high voltage circuit breaker, composing of two core components, namely arc quenching chamber and spring operating mechanism, is the most important control and protective equipment in power transmission system. The motion of arc quenching chamber is driven by spring operating mechanism. In order to investigate further, the following study is conducted concerning the puffer SF6 high voltage circuit breaker. The dynamic mathematical models for arc quenching chamber and spring operating mechanism are established based on the law of energy conservation. The mathematical models of puffer chamber pressure and buffer force is built and studied. The virtual prototype model of circuit breaker is obtained by co-simulation of ADAMS and Matlab. The mechanical displacement characteristics of circuit breaker are simulated, the dynamic force and structural optimum design of parts are calculated and analyzed. The simulation and experimental curves of mechanical displacement characteristics of circuit breaker, which can verify the accuracy of the simulation, is compared and contrasted.
