分闸半轴31上设置有一片分闸铁片37，分闸铁片37整体沿竖直方向设置，分闸铁片37一侧固定在分闸半轴31侧面并且分闸铁片37沿分闸半轴31的径向设置，分闸线圈38固定在壳体1上并且位于分闸铁片37的一侧，分闸线圈38用于对分闸半轴31进行自动的旋转控制。
本申请的一种高可靠高寿命充气柜断路器的工作原理为：电机或手动储能驱动储能动力机构(齿轮传动比Z1/Z2＝21/45)，通过动力机构的储能从动轴拉开储能弹簧机构进行储能。储能完成后，可以通过机械分合闸(即手动旋转分闸半轴组件和合闸半轴组件)及分合闸线圈分合闸。先进行合闸动作，让合闸半轴组件转过一定角度，让合闸楔子脱扣(即V型储能扣从合闸凹口穿过)，把储能弹簧部分能量传递给分合闸传动机构，让分合闸传动机构驱动断路器开关主轴转动，实现合闸；并能部分能量传递给分闸弹簧机构，使弹簧拉开并为分 闸储能；同时储能弹簧可以进行预储能。再进行分闸动作，让分闸半轴组件转过一定角度，让分闸楔子脱扣(即分闸传动拐臂从分闸凹口穿过)，将分闸弹簧的能量传递给分合闸传动机构，让分合闸传动机构驱动断路器开关主轴回位，实现分闸。完成一个循环过程。
本申请通过对断路器个机构的传动结构进行改进设计，并对断路器机构的分合闸的传动机构输入轴拐臂及输出主轴拐臂的外形轮廓进行改进和结构强度优化，解决了现有技术不合理阻尼过大的问题，从而实现了断路器机构机械寿命试验15000次以上；本申请的储能弹簧采用双弹簧结构设计，首先加大了整体的结构强度，延长了使用寿命，其次主弹簧断裂后副弹簧依然能够使用，减少弹簧断裂带来的风险问题；现有断路器机构分闸弹簧机构压缩进行储能且单端固定，可靠性不高，本申请采用分闸弹簧机构拉升进行储能且双端固定，提高可靠性。
本说明书中所描述的以上内容仅仅是对本申请所作的举例说明。本申请所属技术领域的技术人员可以对所描述的具体实施例做各种修改或补充或采用类似的方式替代，只要不偏离本申请说明书的内容或者超越本权利要求书所定义的范围，均应属于本申请的保护范围。
