下面再介绍本发明实施例的模块化弹簧操作机构的各个功能的实现:
1、 储能过程:
所述的电机组件 319通过驱动曲轴 305下方的齿轮 318驱动曲轴 305转动,如图 Ί和 图 8所示, 曲轴 305带动两个棘爪 317驱动棘轮盘 307旋转, 棘轮盘 307带动定位销 308 移动, 定位销 308通过链条 311带动合闸弹簧模块 1装配的链轮轴 107旋转, 链轮轴 107 旋转时通过设在链轮轴 107下端的链条 106,链条 106拉动压板组件 104压缩合闸弹簧 103 储能; 当棘轮盘 307在棘爪 317的驱动下使定位销 308刚过位移的最大点时, 棘轮盘 307 被储能保持组件 310的储能保持掣子 3102挡住限位销 309而停止旋转, 储能动作完成, 机构保持在储能状态。在此运动过程中, 压板组件 104上设置的拨杆 105拨动螺旋滑槽轴 110使储能指示牌 111旋转指示所述模块化弹簧操作机构为储能状态。
2、 合闸过程:
合闸电磁铁 3107受到电磁脉冲而推动储能限位组件 310的合闸掣子 3105旋转,合闸 掣子 3105与储能保持掣子 3102脱离, 储能保持掣子 3102与棘轮盘 307上的限位销 309 脱离, 棘轮盘 307在合闸弹簧 103回复力的作用下带动传动轴 303旋转, 传动轴 303带动 凸轮 306推动刚性的传动拐臂 312旋转, 传动拐臂 312在旋转的过程中压缩分闸弹簧 202 并带动输出轴 304旋转,输出轴 304带动输出拐臂 314和合闸保持拐臂 313旋转进行合闸 动作, 当合闸到位时, 合闸保持掣子 402在复位弹簧 405力的作用下运动到合闸保持拐臂 313的下方, 当合闸保持拐臂 313在分闸弹簧 202回复力的作用下反向运动时与合闸保持 掣子组件 402接触, 由于合间保持掣子组件 402在二级掣子组件 403和分间掣子组件 404 的限制下不能转动,所以合闸保持拐臂 313不能旋转而使本发明模块化弹簧操作机构处于 合闸位置。在此运动过程中合闸弹簧 103释放能量, 压板组件 104上设置的拨杆 105拨动 螺旋滑槽轴 110使储能指示牌 111旋转指示机构为释能状态。同时由于传动拐臂 312的旋 转带动拨杆 315旋转, 拨杆 315拨动辅助开关及计数器模块 5的拨叉 502旋转, 拨叉 502 通过齿轮 503、 504驱动辅助开关 505的轴旋转切换分 /合闸信号, 同时辅助开关 505的轴 带动分 /合闸指示牌 506 旋转指示本发明的模块化弹簧操作机构为合闸状态, 同时设在拨 叉 502上的螺柱 507拉动计数器 508进行分 /合闸操作的计数。
3、 分闸操作:
在本发明模块化弹簧操作机构完成合闸操作而处在合闸位置时,合闸保持模块 4的分 闸电磁铁 408受到电磁脉冲推动分闸掣子组件 402旋转与二级掣子组件 403脱离, 同时二 级掣子组件 403与合闸保持掣子 402脱离, 合闸保持掣子 402与合闸保持拐臂 313脱离, 合闸保持拐臂 313失去支撑后与传动拐臂 312和输出拐臂 314在分闸弹簧 202回复力的作 用下绕输出轴 304旋转,输出轴 304带动输出拐臂 312向分闸的方向旋转而实现分闸操作。 同时由于传动拐臂 312的旋转带动拨杆 315旋转, 拨杆 315拨动辅助开关及计数器模块 5 的拨叉 502旋转,拨叉 502通过齿轮 503、 504驱动辅助开关 505轴旋转切换分 /合闸信号, 同时辅助开关 505的轴带动分 /合闸指示牌 506旋转指示机构为分闸状态 。
4、 防空合及防跳跃的过程:
合闸操作时: 输出拐臂 312在合闸过程中带动拨销 316拨动防空合组件 320的拨叉 3202, 拨叉 3202拨动限位销 3203移动到合闸掣子 3105的前方, 此时若有合闸信号, 由 于合闸掣子 3105被限位销 3203阻挡,合闸电磁铁 3107无法推开合闸掣子 3105实现合闸, 从而实现防空合的目的; 若多次或连续施加合闸信号时, 由于上述防空合组件 320对合闸 状态的锁定, 能有效的防止断路器跳跃现象的发生。
综上所述, 虽然本发明已以较佳实施例揭示如上, 然其并非用以限定本发明, 本领域 技术人员应当意识到在不脱离本发明所附的权利要求所揭示的本发明的范围和精神的情 况下所作的更动与润饰, 均属本发明的权利要求的保护范围之内。
