还包括一第二复位弹簧 152, 在所述的触发转块 37被按压后, 所述的第五联动 块 14与触发转块 37分离, 所述的第二复位弹簧 152用以使所述的第五联动块 14 绕轴转动。 . . .
请参阅图 5所示, 其为本发明具有机械式短路自锁功能的框架式断路器短路自 锁功能部分机械分解立体示意图;其为本发明的重点所在,从功能实现上讲其包括: 一短路检测件, 其在所述的框架式断路器本体中处于轴接状态, 当连接所述框 架式断路器本体 1的相线出现短路故障, 则必然形成强磁场, 由于所述的短路检测 件为轴接状态, 则会产生一旋转机械动作; 所述的短路检测件为至少一导磁转动件 23 , 也可以具有三个导磁转动件 23分别和每一个出线连接块 112对应, 在产生短 路磁场时, 其产生转动动作, 一复位弹簧 251设置于所述的导磁转动件 23的转轴 上, 所述的导磁转动件 23 绕轴转动, 并具有一感应段和一按压段, 所述的感应段 位于所述的出线连接块 112或进线连接块 111附近, 本实施例是设置于所述的出线 连接块 112下部。
一短路动作触发机构, 其与所述的短路检测件相结合, 并具有的一触发端与所 述的框架式断路器本体 1中的分断机构相结合, 在所述的短路动作触发机构因所述 的短路检测件的旋转机械动作产生联动时, 所述的触发端触发所述的分断机构产生 分断动作; 所述的短路动作触发机构包括:
第一联动件 241, 其绕一轴转动, 其第一端与所述导磁转动件 23的按压段相抵 靠, 还包括: 一复位弹簧 252设置于所述的第一联动件 241的轴上, 用以实现其复 位;
第一联动杆 242 , 其第一端与所述第一联动件 241的第二端相连接;
一转轴 245, 所述的第一联动杆 242的第二端带动所述的转轴 245转动; 一触发部 246, 其套设在所述的转轴 245上, 并且与所述的触发转块 37上的按 压部相对应, 通过按压所述的按压部使所述的框架式断路器本体 1产生断路动作。
当然在短路故障发生时, 上述结构已经可以实现所述的框架式断路器本体的跳 闸动作, 但是一旦跳闸新电后上述的短路动作触发机构因为没有磁场作用在复位弹 簧 251、 252 的作用下就会复位, 相应的合闸命令就能令所述的框架式断路器本体 重新合闸, 但是如果短路故障没有解除, 则又会通过上述作为短路检测件的导磁转 动件 23 以及短路动作触发机构联动, 从而实现再次的断路动作, 周而复始从而使 所述的框架式断路器本体不断的在合闸和跳闹之间切换, 从而会对所述的框架式断 路器本体自身的寿命, 或是电网的其他设备造成影响。
为了实现较佳的技术效果, 本发明还提供一个机械式自锁机构, 其使所述的分 断机构不能自动复位。 其中, 所述的机械式自锁机构包括:
一圓环 247, 其与所述的转轴 245相固接, 所述的圓环 247的内侧设有自锁缺 槽 2471;
一自锁外壳 22, 其上具有一缺口 221, 所述的自锁外壳 22 固定在所述的框架 式断路器本体 1外壳上;
一自锁块 21 , 其内部设有一第三复位弹簧, 并具有一自锁端, 其与所述的圓环 247内环相抵靠, 当发生短路时, 所述的自锁端嵌入所述的自锁缺槽 2471。
请参阅图 6A和图 6B所示, 其分别为本发明具有机械式短路自锁功能的框架式 断路器正常状态下未合闸剖视示意图以及正常状态下未合闹侧视示意图; 此时本发 明所述的具有机械式短路自锁功能的框架式断路器处于断路状态, 所述的导电动触 块 113与所述的进线连接块 111分离; 所述的导磁转动块 113在所述的出线连接块 112 下部, 因没有短路磁场所以没有转动; 同时所述的短路动作触发机构也处于正 常状态; .所述的自锁块 21与所述的自锁缺槽.2471分离。
请参阅图 7A和图 7B所示, 其分别为本发明具有机械式短路自锁功能的框架式 断路器正常状态下合闸后剖视示意图以及正常状态下合闸后侧视示意图; 与上图相 比较, 此时本发明所述的具有机械式短路自锁功能的框架式断路器处于通路状态, 所述的导电动触块 113与所述的进线连接块 111接触; 所述的导磁转动块 113在所 述的出线连接块 112下部, 因没有短路磁场所以没有转动; 同样所述的短路动作触 发机构也处于正常工作的状态; 所述的自锁块 21与所述的自锁缺槽 2471分离。
请参阅图 8A和图 8B所示, 其分别为本发明具有机械式短路自锁功能的框架式 断路器短路状态剖视示意图以及短路状态侧视示意图, 此时由于短路发生, 从而产 生强大的磁场, 所述导磁转动件 23的感应段向所述的出线连接块 112摆动, 从而 使所述的按压段按压所述的第一联动件 241, 从而使所述的第一联动件 241摆动, 从而顶推所述的第一联动杆 242 , 进而使所述的转轴 245转动, 然后所述的触发部 246摆动, 造成了对所述的触发转块 37上的按压部的按压, 通过按压所述的按压部 使所述的框架式断路器本体 1产生断路动作。
同时所述的圆环 247因所述的转轴 245转动, 从而使所述的自锁块 21的自锁 端嵌入所述的自锁缺槽 2471, 并在所述的第三复位弹簧 211的顶推下, 从所述自锁 外壳 22上的缺口 221上伸出。
这样虽然所述的框架式断路器本体处于断路状态, 此时短路造成的强磁场消 失, 所述的导磁转动件 23在所述的复位弹簧 251的作用下复位。 但是由于自锁块 21伸出所述自锁外壳 22上的缺口 221 ,使所述的自锁端无法与所述的自锁缺槽 2471 分离, 这样所述的转轴 245无法转动, 这样所述的触发部 246仍然按压在所述的触 发转块 37上的按压部上, 从而形成自锁。
请参阅图 9A和图 9B所示, 其分别为本发明具有机械式短路自锁功能的框架式 断路器短路状态发生后剖视示意图以及短路状态发生后侧视示意图; 其是经过人为 的将所述的自锁块 21按回到所述的自锁外壳 22内, 使所述的自锁端与所述的自锁 缺槽 2471分离, 这样通过设置在所述第一联动件 241的转轴上的复位弹簧 252使 所述的触发部 246与所述的触发转块 37上的按压部分离, 实现解锁, 然后才能实 现再次合闸。 .
并且在发生短路的情况下, 引起断路动作, 通过所述的自锁块 21从所述自锁 外壳 22上的缺口 221上伸出, 起到了指示作用。
以上所述仅为本发明的较佳实施例, 对本发明而言仅仅是说明性的, 而非限制 性的。 本专业技术人员理解, 在本发明权利要求所限定的精神和范围内可对其进行 许多改变, 修改, 甚至等效, 但都将落入本发明的保护范围内。
