摘要:
针对真空断路器在增加触头弹簧压力时弹簧操动机构不能可靠分合的问题,在不改变储能弹簧和分闸弹簧能量的前提下,对环网柜用真空断路器弹簧操动机构凸轮轮廓、传动拐臂尺寸和角度、连板尺寸进行优化,建立优化后弹簧操动机构的数学模型,分别进行MATLAB和ADAMS仿真。MATLAB仿真结果表明,机构的出力特性与断路器的负载特性能够实现良好匹配,优化后触头弹簧压力为2 327 N,较优化前效率提高132%。动力学仿真显示,优化后的触头弹簧压力提高为2 286 N。试验表明,装配2 100 N触头弹簧压力时机构能可靠分合,合闸速度减小到065 m·s-1,合闸弹跳减小,验证了优化方案的有效性和可靠性。
Abstract:
Aiming at solving the problem of unsteady opening and closure of the spring operating mechanism of the vacuum circuit breaker at increased contact spring pressure,without changing the energy of the energy storage spring or the opening spring,an optimized spring operating mechanism is established in which its contour,the size and angle of the driving arm,and the size of the connecting plate are optimized,and the MATLAB and ADAMS simulations are performed respectively.MATLAB simulation results show that the output characteristics of the mechanism is well matched with the load characteristics of the circuit breaker,and the optimized contact spring pressure reaches 2 327 N,13.2% higher than the efficiency before optimizationdynamic simulation shows that the optimized contact spring pressure is increased to 2 286 Nthe test shows that the mechanism assembled with 2 100 N contact spring pressure can be opened and closed reliably with a reduced closing speed at 0.65 m·s-1 and reduced closing bounce,which verifies the effectiveness and reliability of the optimized scheme.
