Gaoya dianqi, 2004 对与真空断路器相配的弹簧操动机构而言,其输出力特性和开关负载特性的合理匹配取决于凸轮机构的合理设计。按全程输出力大于阻力的原则,采用分段多项式方法确定了凸轮轮廓线。凸轮机构的理论计算与试验结果比较吻合,表明该方法能够有效地实现凸轮机构的优化设计,在满足操动机构运动特性的前提下,可降低弹簧刚度和输出力。

Gaoya dianqi, 2020 为了实现负荷开关弹簧操作机构的故障诊断,建立了储能电机的动态仿真模型对储能电机电流和操作机构力矩关系进行了验证,同时进行了故障模拟试验,测量并分析了负荷开关操作机构分合闸弹簧卡涩、传动齿轮卡涩的储能电机电流的变化规律,并与正常情况下的结果进行了对比,研究了储能电机电流的特征量对操作机构状态的影响,并采用皮尔森相关系数法对特征量进行降维处理;针对负荷开关操作机构出现的主要故障问题,采用基于决策树的支持向量机实现对负荷开关正常状态、传动齿轮卡涩、储能弹簧卡涩的3种状态进行辨识 ...

Gaoya dianqi, 1985 扭簧是操动机构里常用的复位弹簧。为保证机构动作可靠,在设计扭簧时,应对它的回复时间进行验算。 现举一例:下图a～d是CD10直流电磁操动机构合闸过程的示意图。扭簧5起着使支架2复位的作用。当合闸线圈通电后 ...
