具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限 制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。此外，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“设置”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
请参照图1至图3，本实施例提供一种远程分闸机构，包括壳体、储能组件110和脱扣组件120，储能组件110包括锁扣111、储能簧112、转轴113以及与转轴113连接的储能盘114，储能盘114上设置有抵持部1142，储能簧112的第一端与壳体卡接，储能簧112的第二端能够与抵持部1142抵持；锁扣111包括与壳体铰接的铰接部1111、对储能簧112的第二端限位的限位部1112，以及与脱扣组件120配合的脱扣部1113，锁扣111与壳体之间设置有弹性件130，以使脱扣部1113具有朝向脱扣组件120运动的趋势；脱扣组件120用于使限位部1112解除对储能簧112的第二端的限位，以使转轴113转动至分闸位置。
具体的，本发明实施例对转轴113与储能盘114之间的连接形式不作具体限制，只要能够满足所需的传动需求和稳定的连接即可。示例的，转轴113与储能盘114之间可采用固定连接的形式，如铆接、焊接或一体成型等，也可采用装配连接的形式，如套接、卡接或螺纹连接等形式。
另外，本申请对储能簧112的设置位置不作具体限制，示例的，储能簧112可以套设在转轴113上，也可以设置在壳体上，只要能够保证储能簧112的第一端卡接固定，第二端能够与储能盘114的抵持部1142相抵持，以使转轴113转动时，能够使储能簧112储能即可。在储能簧112套设在转轴113上时，储能簧112可采用扭簧的形式；在储能簧112设置在壳体上时，可以采用扭簧的形式，也可以采用拉伸弹簧或压缩弹簧的形式，采用拉伸弹簧或压缩弹簧时，壳体上对应设置有拉伸弹簧或压缩弹簧伸缩的通道即可。
可以理解的，脱扣组件120用于接收控制信号，根据控制信号动作，能够使锁扣111解除对储能簧112第二端的限位即可。示例的，可以向脱扣部1113施加作用力，使脱扣部1113向远离脱扣组件120所在位置运动。当脱扣部1113向脱扣组件120远离过程中，锁扣111的铰接部1111与壳体之间发生相对转动，使得锁扣111的限位部1112发生位置移动，不再对储能簧112的第二端进行限位，储能簧112便可以恢复弹性形变，带动储能盘114转动，使储能盘114转动至分闸的位置，从而完成旋转开关的分闸操作。
本发明实施例提供的远程分闸机构，通过转轴113以及与转轴113连接的储能盘114，储能盘114上设置有抵持部1142，储能簧112的第一端与壳体卡接，储能簧112的第二端与抵持部1142相抵持，当转动转轴113使储能盘114跟随转轴113同步转动时，储能盘114的抵持部1142推动储能簧112的第二端跟随储能盘114运动，而储能簧112的第一端与壳体卡接，在储能盘114运动过程中使储能簧112发生弹性形变，进而产生弹性势能，同时使旋转开关合闸。锁扣111包括与壳体铰接的铰接部1111、对储能簧112的第二端限位的限位部1112，以及与脱扣组件120配合的脱扣部1113，锁扣111与壳体之间设置有弹性件130，以使脱扣部1113具有朝向脱扣组件120运动的趋势。由于脱扣部1113具有朝向脱扣组件120运动的趋势，且锁扣111的铰接部1111与壳体铰接，在储能盘114的抵持部1142推动储能簧112的第二端跟随储能盘114运动过程中，储能簧112的第二端与限位部1112卡接，使得储能簧112产生的弹性势能得以保持。当脱扣组件120动作时，克服弹性件130的作用力推动脱扣部1113朝向远离脱扣组件120运动，使得储能簧112的第二端脱离锁扣111的限位部1112，锁扣111不再对储能簧112的第二端进行限位，储能簧112恢复弹性形变的过程中，通过储能盘114的抵持部1142带动储能盘114往回转动，以使旋转开关分闸。分闸过程中通过储能簧112积蓄的弹性势能实现，无需通过电机带动，能够提升旋转开关切换时的响应时间。
如图5所示，壳体包括上盖140，上盖140上设置有限位槽142，储能簧112的第一端通过限位槽142与壳体卡接。这样一来，可以使储能簧112的第一端与壳体之间位置的相对固定，有利于提升储能簧112使用时的稳定性，确保储能簧112能够正常储能，并在恢复弹性形变过程中带动储能盘114转动，有利于提升分闸时的稳定性。
请再参考图5，上盖140上还设置有空心柱144,转轴113穿过空心柱144，且与上盖140转动连接。具体的，转轴113连接于上盖140的内侧和外侧，以通过转轴113与旋转开关进行交互操作。通过将转轴113穿过空心柱144设置，可以提升转轴113转动时的平稳定，避免转轴113在径向 上晃动，有利于提升转动连接时的精度和稳定性。
如图5和图6所示，储能簧112包括储能本体1122，以及分别与储能本体1122连接的第一扭臂1124和第二扭臂1126，储能本体1122套设于空心柱144外圈。
具体的，通过将储能本体1122套设于空心柱144外圈，可以对储能簧112进行限位，防止储能簧112侧向偏移，影响储能簧112的第一端(即第一扭臂1124)与壳体之间的卡接。同时，也可以保证储能簧112的第二端(即第二扭臂1126)与储能盘114上抵持部1142的抵持，避免发生错位，影响储能簧112的储能。另外，也使得储能簧112的第二扭臂1126与锁扣111上的限位部1112更好的配合，避免因储能簧112晃动造成第二扭臂1126与限位部1112之间脱离，影响储能簧112的储能。
采用上述设置形式，不仅能保证储能簧112使用时的稳定性，也可以使储能簧112、上盖140和转轴113之间的配合更加紧凑，充分利用内部空间，有利于实现远程分闸机构的小型化。
如图3和图4所示，铰接部1111与限位部1112之间设置有导向面1114，限位部1112背离导向面1114的一侧设置有限位面1115。
具体的，当转轴113带动储能盘114转动时，储能盘114上的抵持部1142带动第二扭臂1126跟随储能盘114转动，在第二扭臂1126运动时，第二扭臂1126与导向面1114抵持，并沿着导向面1114向限位部1112所在位置移动。当第二扭臂1126移动至限位部1112背离导向面1114的一侧，即第二扭臂1126移动至限位部1112设置有限位面1115的一侧时，第二扭臂1126被限位部1112限位，即使储能盘114不再对第二扭臂1126施加作用力，第二扭臂1126也不能恢复至初始状态，从而实现对储能簧112的储能操作。
当脱扣组件120收到脱扣信号时，脱扣组件120动作，以使脱扣部1113克服弹性件130的作用力向远离脱扣组件120所在位置运动，在脱扣部1113运动过程中，限位面1115对储能簧112的第二扭臂1126的限位量逐渐减小，直至第二扭臂1126脱离限位部1112的限位作用。在第二扭臂1126脱离锁扣111的限位部1112作用后，储能簧112积蓄的弹性势能释放，通过抵持部1142带动储能盘114向分闸位置转动，以使旋转开关分闸。
如图4所示，脱扣部1113与限位部1112之间设置有限位凸起1116，壳体还包括与上盖140连接的安装基座(图中未示出)，限位凸起1116与安装基座配合，以对锁扣111进行限位。
具体的，在脱扣组件120恢复至动作前的状态时，锁扣111在弹性件130的作用下，使得锁扣111通过铰接部1111转动，以使脱扣部1113具有朝向脱扣组件120运动的趋势。通过在脱扣部1113与限位部1112之间设置的限位凸起1116，在脱扣部1113向脱扣组件120运动的过程中，使得安装基座对锁扣111的运动范围进行限位，避免脱扣部1113与脱扣组件120之间撞击，有利于提升脱扣组件120使用时的稳定性。
在本发明的可选实施例中，弹性件130可设置在锁扣111与上盖140之间，或，弹性件130设置在锁扣111与安装基座之间。
具体的，当弹性件130设置在锁扣111与上盖140之间时，该弹性件130可以采用压缩弹簧或者弹片等形式，以使锁扣111与上盖140之间具有斥力，从而使得脱扣部1113具有朝向脱扣组件120运动的趋势。当弹性件130设置在锁扣111与安装基座之间时，该弹性件130可以采用拉伸弹簧或者弹性绳等形式，以使脱扣部1113具有朝向脱扣组件120运动的趋势。确保限位部1112能够对储能簧112的第二扭臂1126稳定的限位。
如图7所示，锁扣111包括支撑本体1117，脱扣部1113包括与支撑本体1117连接的折边1118，以及与折边1118连接的受力部1119。具体的，折边1118所在平面与支撑本体1117所在平面具有预设夹角，该夹角优选为90°，这样一来，可以提升锁扣111与脱扣组件120的接触可靠性，保证脱扣组件120动作时能够可靠驱动锁扣111，使锁扣111解除对储能簧112的限位。
可选地，脱扣组件120为磁通变换器、分离脱扣器、欠压脱扣器、过压脱扣器的任意一种。以通过电信号来控制脱扣组件120的动作，从而使锁扣111解除对储能簧112的限制，以使旋转开关急速响应，实现远程分闸功能。
本发明实施例还公开了一种旋转开关，包括前述实施例中的远程分闸机构，以及与远程分闸机构连接的通断组件，通断组件包括静触头组件以及与远程分闸机构传动连接的动触头组件。通过远程分闸机构带动静触头组件运动，以实现分闸或合闸。该旋转开关包含与前述实施例中的远程分闸机构相同的结构和有益效果。远程分闸机构的结构和有益效果已经在前述实施例中进行了详细描述，在此不再赘述。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
