具体实施方式
以下结合附图给出的实施例，进一步说明本发明的旋转隔离开关的具体实施方式。本发明的旋转隔离 开关不限于以下实施例的描述。
如图1-2所示，为本发明旋转隔离开关的一个实施例。
本实施例的旋转隔离开关包括操作机构和开关本体，开关本体包括转动设置的支持轴10以及至少一组接触系统，接触系统包括配合使用的动触头和静触头，支持轴10用于承载动触头，也即是动触头安装在支持轴10上，操作机构与支持轴10传动相连而驱动动触头与静触头闭合和断开，即旋转隔离开关合闸和分闸。进一步的，所述开关本体包括两组及两组以上的接触系统，各接触系统上下层叠设置，操作机构层叠在最上方的接触系统上，各接触系统的动触头均设置在支持轴10上，支持轴10与操作机构驱动相连，操作机构通过支持轴10驱动各动触头同步转动，分别与对应的静触头闭合和分断。参见图1-2，所述操作机构包括旋钮，外力转动旋钮驱动操作机构动作，进而驱动操作机构的转轴11转动，同时转轴11驱动支持轴10转动，实现各动触头的同步转动。

进一步的，如图12-13所示，所述转盘60与相邻触头支持40通过插接结构传动相连。进一步的，所述开关本体中，各相邻触头支持40通过插接结构传动相连(图中未示出)。上述结构设计有利于简化装配操作，提高装配效率。具体的，所述插接结构包括插头和插孔，一个设置在触头支持40上，另一个设置在转盘60上，也即是，触头支持40和转盘60中，一个设有插头，另一个设有插孔，本实施例中触头优选设置在触头支持40上，插孔优选设置在转盘60上；所述插头包括主插头40-101和副插头40-100，轴线o-o从主插头40-101中部穿过，两组副插头40-100分别设置在主插头40-101两侧；所述插孔包括主插孔60-5和副插孔60-6，分别与主插头40-101和副插头40-100对应配合，两组副插孔60-6分别设置在主插孔60-5两侧。进一步的，所述主插头40-101的横截面为长条形结构，副插头40-100的横截面为扇面形结构，两组副插头40-100对称设置在主触头40-101两侧。进一步的，两组所述副插头40-100的圆心在轴线o-o上。
进一步的，如图10、12-13所示，所述转盘60包括转盘连接孔60-1，转盘连接孔60-1位于转盘60的转动中心的一侧，也即是转盘连接孔60-1位于轴线o-o一侧，传动杆1转动插置在转盘连接孔60-1内；所述转轴11往复转动时，通过传动杆1与转盘连接孔60-1配合，驱动转盘60绕轴线o-0转动设置。
进一步的，如图13所示，所述转盘60还包括加强围挡60-10，加强围挡60-10设置在转盘连接孔60-1面向机构支架0的一端外侧，加强围挡60-10有利于增强转盘连接孔60-1的结构强度，延长转盘60的使用寿命。
进一步的，如图12所示，所述转盘60还包括转盘主板60-3和转盘轴台60-2，转盘连接孔60-1设置在转盘主板60-3上，转盘轴台60-2设置在转盘主板60-3背离机构支架s的一侧上，也即是转盘轴台60-2设置在转盘主板60-3面向开关本体200的一侧上；所述操作机构100的机构壳体h设有转盘轴孔，转盘轴台60-2转动设置在转盘轴孔内。

进一步的，如图10和22所示，所述操作机构还包括机构壳体h和主体，主体包括机构支架0、连杆结构、驱动轴结构、转轴11和传动结构34，主体和转盘60均设置在机构壳体h内，转盘60在其轴向上位于主体一侧；所述转盘60包括转盘连接孔60-1和防呆结构，传动杆1一端为用于与转盘连接孔60-1插接配合的插接端，防呆结构用于与未插入转盘连接孔60-1内的插接端相抵，阻止主体安装到位。装配时，所述转盘60先于主体装入机构壳体h内，插入端未插入转盘连接孔60-1内，则插接端与防呆结构相抵，阻止主体安装到位，也即使主体不能以正确姿态装入机构壳体h内。所述防呆结构可避免传动杆1与转盘60在未正确组装的情况下，阻止主体在机构壳体h内安装到位，从而避免因主体和转盘60未正确组装而返工，提高产品组装的合格率和效率。
进一步的，如图22所示，所述转盘60面向主体的一侧为配合侧；所述防呆结构为设置在配合侧上的挡面，也即是，主体在装入机构壳体h内的过程中，若传动杆1的插接端未插入转盘60的转盘连接孔60-1内，则插接端抵压在挡面上，使主体不能安装到位，从而提示操作人员存在安装不正确的情况发生。
进一步的，所述转盘60的最大转动角度为行程角度；在垂直于所述转盘60的转动轴线(也即是轴线o-o)的投影上，挡面至少覆盖两个弧形区域，每个弧形区域一端与转盘连接孔60-1相连，每个弧形区域的圆心均与转盘60的转动中心重合，每个弧形区域的圆心角为行程角度的一半，两个弧形区域以转盘连 接孔60-1的圆心与转盘60的转动中线为对称轴对称分布。
具体的，如图5所示，所述转盘60包括转盘主板60m和转盘外延板，转盘外延板环绕转盘主板60m的周向侧面设置，转盘外延板的圆心角小于360°，也即是转盘外延板是环绕转盘60m的周向侧面设置的弧形板；在垂直于所述转盘60的转动轴线的投影上，两个弧形区域的外沿(也即弧形区域远离转盘60的转动中心的侧沿)在转盘外延板上，弧形区域的内沿(也即是弧形区域靠近转盘60的转动中心的侧沿)位于转盘外延板上(也即是弧形区域整个都位于转盘外延板上)或者位于转盘主板60m上(也即是弧形区域沿转盘60的径向跨设在转盘主板60m和转盘外延板上)，转盘主板60m和转盘外延板面向主体的一侧共平面为主平面60-3p；所述转盘60还包括设置在主平面60-3p上的第一凸台和第二凸台，第一凸台和第二凸台沿转盘60的轴向凸起设置，转盘连接孔60-1设置在第一凸台上，第一凸台的台面为第一台面60-1p，第二凸台的台面为第二台面60-2p，第一台面60-1p、第二台面60-2p和主平面60-3p沿转盘60的轴向依次平行设置且逐次远离主体，第一台面60-1p与转盘连接孔60-1的入口端平齐。上述结构设计，既保证了转盘连接孔60-1的外侧壁的结构强度，增加了转盘60的使用寿命，又起到了防呆作用，减少了材料用量，降低了生产成本，而且提高了转盘60的整体结构强度。装配时，所述传动杆1的插接端未插入转盘60的转盘连接孔60-1内，则随着传动杆1与转盘60的相对位置的变化，插接端抵靠在第一挡面60-1p或第二挡面60-2p或第三挡面60-3p上。
作为其它实施例，所述挡面至少覆盖与转盘连接孔60-1的直径等宽的环形区域，转盘连接孔60-1在其轴向上的投影上位于环形区域内，从而无论转盘60转动角度是多少，传动杆1的插接端只要没有插入转盘连接孔60-1内，就会与挡面相抵。当然，由于操作机构的结构设计的限制，转盘60仅可以在一定角度范围内转动。进一步的，所述挡面覆盖配合侧除转盘连接孔60-0以外的全部区域，有利于降低转盘60的设计难度。
如图15-19所示，所述连杆结构还包括设置在锁扣件13和再扣件14之间的复位弹簧27；所述再扣件14包括弯折相连的竖臂14-0和横臂14-1；复位弹簧27的两个弹簧臂分别与锁扣件13和竖臂4-0配合；所述操作机构正常分闸和合闸状态时，锁扣件13和跳扣件12保持搭扣配合且与横臂14-1保持第一限位配合；所述再扣件14受外力驱动而转动，横臂14-1解除与锁扣件13的第一限位配合，锁扣件13和跳扣件12分别转动而解除搭扣配合，操作机构脱扣，锁扣件13与横臂14-1建立第二限位配合；所述横臂14-0包括设置在其面向锁扣件13一侧上的弹簧限位槽14-01以及设置在弹簧限位槽14-01一侧的避让缺口14-00；所述复位弹簧27与竖臂14-0配合的弹簧臂(以下称为第二臂27-2)被拨动，经由避让缺口14-00进入弹簧限位槽14-01内，具体是：装配时，复位弹簧27首先被套设在弹簧轴上且复位弹簧27与锁扣件13配合的弹簧臂(以下称为第一臂27-1)被置于再扣件14和锁扣件13之间，然后第二臂27-2被外力拨动，由竖臂14-0一侧(背离锁扣件13的一侧)经由避让缺口14-00摆动至竖臂14-0另一侧(面向锁扣件13的一侧)，然后将第二臂27-2放置在弹簧限位槽14-01内从而完成复位弹簧27的装配，在第二臂27-2被拨动的过程中，第一臂27-1始终抵靠在锁扣件13上。现有操作机构组装时，复位弹簧的两个弹簧臂，一个紧靠锁扣件的锁扣件主体，另一个抵靠在再扣件的弹簧限位槽内，然后外力克服复位弹簧的弹力，将再扣件装配在支架上；所述复位弹簧在储能状态下被装入支架，易导致再扣件和锁扣件倾斜，需装配后进行校正，影响装配效率。本发明操作机构组装时，再扣件14的避让缺口14-00和弹簧限位槽14-01的结构设计，使得操作机构在组装过程中，可以先完成锁扣件13、再扣件14、复位弹簧27和弹簧轴，与机构支架0的装配，在机构支架0的上侧板6和下侧板7完成彼此固定后(例如上侧板6和下侧板7通过连接轴固定连接在一起)，然后再完成复位弹簧27与再扣件14之间的装配，从而简化了装配操作，降低了复位弹簧27的装配难度，提高了装配效率。
如图16和17所示，所述复位弹簧27使锁扣件13和再扣件14具有向同一方向转动的趋势。具体的，如图16和17所示方向，所述复位弹簧27使锁扣件13和再扣件14均具有向顺时针方向转动的趋势。进一步的，所述锁扣件13的锁扣件主体13-0的两端分别为锁扣件枢置端和锁扣件配合端，锁扣件主体13-0通过锁扣件枢置端转动设置在机构支架0上；所述再扣件14的横臂14-1与锁扣件配合端相对，竖臂14-0的自由端(也即是竖臂14-0远离横臂14-1的一端)与锁扣件枢置端相对；所述复位弹簧27的两个弹簧臂中，一个与锁扣件配合端配合，另一个与竖臂14-0的自由端配合，从而使锁扣件13和再扣件14具有向同一方向转动的趋势。
如图15-17所示，所述锁扣件13通过第八轴8s转动设置在机构支架0上，第八轴8s作为弹簧轴，有利于减少操作机构的零部件数量。
作为其它实施例，如图20-21所示，所述复位弹簧27为扭簧，锁扣件13包括设置在锁扣件主体13-0上的弹簧支撑臂13-3，复位弹簧27套设在弹簧支撑臂13-3上，一个弹簧臂与锁扣件13配合，另一个弹簧臂与再扣件14配合。进一步的，所述锁扣件13还包括锁扣件支撑指13-2，两个锁扣件支撑指13-2分别设置在锁扣件主体13-0分别靠近机构支架0的上侧板6和下侧板7的两端上，两个锁扣件支撑指13-2分别转动设置在上侧板6和下侧板7上，上侧板6和下侧板7优选分别设有锁扣件转轴孔，两个锁扣件支撑指13-2分别转动插置在两个锁扣件转轴孔内。进一步的，所述锁扣件主体13-0包括锁扣件主板13-00和锁扣件侧板13-01，两个锁扣件侧板13-01相对且分别与锁扣件主板13-00两端弯折相连，两个锁扣件支撑指13-2分别设置在两个锁扣件侧板13-01上，弹簧支撑臂13-3一端与一个锁扣件侧板13-01弯折相连且与锁扣件主板13-00并排相对，锁扣件长臂13-1一端与锁扣件主板13-00弯折相连。作为上述实施例的一种变形，所述锁扣件13还可以不设置锁扣件支撑指13-2，而是两个锁扣件侧板13-01通过第八轴8s转动设置在机构支架0上，第八轴8s穿过两个锁扣件侧板13-01且两端分别设置在上侧板6和下侧板 7上。
另外需要指出的，所述复位弹簧27并不仅限于扭簧，其可以设置在机构支架0或锁扣件13上，只要其具有两个分别与锁扣件13和再扣件14配合的弹簧臂，分别向锁扣件13和再扣件14施加作用力，使二者具有向同一方向转动的趋势即可；例如，所述复位弹簧27为V形弹簧片，其折弯处设置在机构支架0或锁扣件13上，其两个弹簧臂分别与锁扣件13和再扣件14配合。
如图18-19所示，所述再扣件14中，竖臂14-0一端与横臂14-1弯折相连，另一端的面向锁扣件13的一侧设有弹簧限位槽14-01，竖臂14-0和横臂14-1的弯折连接处转动设置在支架13上。进一步的，所述竖臂14-0包括竖臂主板14-02、竖臂侧板14-03和竖臂加强筋14-04，两块竖臂侧板14-03并排且分别与竖臂主板14-02弯折相连，两块竖臂侧板14-03优选与竖臂主板14-02两端弯折相连且整体的横截面呈ㄩ形结构，竖臂主板14-02和竖臂侧板14-03一端分别与横臂14-1一侧相连，竖臂侧板14-03优选与横臂14-1两端弯折相连且整体ㄩ形结构，竖臂加强筋14-04设置在竖臂主板14-02中部且位于两块竖臂侧板14-03之间，竖臂加强筋14-04两端分别与两块竖臂侧板14-03相连且与横臂14-1并排，弹簧限位槽14-01靠近一块竖臂侧板14-03设置，弹簧限位槽14-01和横臂14-1分别位于竖臂加强筋14-04两侧。所述再扣件14整体为框架型结构，结构简单且强度高，而且整体质量轻巧，节约生产材料和成本。
如图17-18所示，所述再扣件14还包括设置在横臂14-1上的限位面14-100，锁扣件13通过锁扣件主体13-0转动设置在机构支架0上；所述操作机构在脱扣状态下，限位面14-100抵靠在锁扣件主体13-0一端上而阻止再扣件14复位，也即是阻止再扣件14在复位弹簧27的作用力下转动，再扣件14与锁扣件13保持在第二限位配合状态，无法切换至第一限位配合状态。进一步的，所述再扣件14包括设置在横臂14-1上的限位凸台14-10，限位凸台14-10面向竖臂14-0的侧面为限位面14-100。进一步的，所述操作机构在脱扣状态下，限位面14-100与锁扣件主体13-0的一端线接触或面接触。具体的，所述操作机构在脱扣状态下，限位面14-100与锁扣件主体13-0的锁扣件配合端的端头线接触。
如图17所示，所述再扣件14的竖臂14-0的中心线与限位面14-100的夹角α＞90°，从而保证操作机构再扣时，锁扣件13能顺利与限位面14-100分离而复位，避免再扣件14和锁扣件13发生死扣，导致操作机构失效。
如图19所示，所述再扣件14的竖臂侧板14-03与横臂14-1相连的一端设有供第九轴9s穿过的再扣轴孔。
如图18-20所示，所述再扣轴14还包括设置在竖臂14-0上的行程限位轴14-2，机构支架0上设有行程限位孔，行程限位轴14-2活动插置在行程限位孔内，限定再扣件14的转动行程。进一步的，所述再扣件14包括分别设置在竖臂14-0两侧上的两个行程限位轴14-2(具体的，两个所述行程限位轴14-2分别设置在竖臂14-0的两个竖臂侧板14-02上)，机构支架0的上侧板6和下侧板7均设有行程限位孔，两个行程限位轴14-2分别活动插置在两个行程限位孔内。
如图15-17所示，所述操作机构脱扣后，锁扣件13与跳扣件12相抵，阻止锁扣件13复位，从而避免锁扣件13与跳扣件12恢复搭扣配合时形成死扣，而且在摇臂5驱动跳扣件12转动以与锁扣件13恢复搭扣配合的整个过程中，跳扣件12始终抵压锁扣件13，直至二者恢复搭扣配合。具体的，如图15-17、21所示，所述锁扣件13包括锁扣件长臂13-1，操作机构在脱扣状态下，跳扣件12与锁扣件长臂13-1相抵阻止锁扣件13复位，也即是锁扣件13在复位弹簧27和跳扣件12的共同作用下保持静止状态。进一步的，所述锁扣件长臂13-1一端与锁扣件13的锁扣件主体13-0相连，另一端与跳扣件12配合。
如图11和14所示，所述操作机构还包括缓冲件41，操作机构分闸时，输出结构撞击并停靠在缓冲件41上，输出结构包括转轴11和传动杆1，也即是，操作机构分闸时，输出结构撞击缓冲件41使输出结构停止转动(也即是使转轴11停止转动)，输出结构最终抵靠在缓冲件41上而停留在断开位置上，此时输出结构也带动动触头机构停留在其断开位置上。所述缓冲件41由柔性材料制成，例如塑料、橡胶等，对操作机构起到缓冲作用，确保操作机构在分闸过程中不会因硬力撞击而脱扣，致使操作机构瓦解。进一步的，所述输出结构的传动杆1，在操作机构分闸时，撞击并停靠在缓冲件41上。进-步的，所述缓冲件41通过缓冲件装配部固定在机构支架0上，缓冲件缓冲部设置在缓冲件装配部上，缓冲件缓冲部位V形板结构，其两端分别与缓冲件装配部相连且尖端朝向转轴11。当然，所述缓冲件缓冲部还可以是其他形状的结构，例如弧形板、波浪形板或单层板等，还有其他多种形式，在此不再一一列举。
作为其它实施例，所述操作机构分闸时，输出结构的转轴11撞击并停靠在缓冲件41上。
如图11和14所示，所述转轴11包括转轴侧板11a和转轴连接板11b，两块转轴侧板11a相对间隔设置且分别与转轴连接板11b弯折相连，两块转轴侧板11a中部绕轴线o-o转动，两端分别与连接结构、传动杆1传动相连。进一步的，两块所述转轴侧板11a转动设置在机构支架0上，一端通过第四轴4s与第二连杆15转动相连，另一端用于与动触头机构传动相连(该端用于与传动杆1相连，且通过传动杆1驱动转盘60转动，转盘60带动动触头机构转动)。进一步的，两块所述转轴侧板11a均设有转轴轴孔，两块转轴侧板11a通过转轴轴孔套设在驱动轴结构的驱动轴2上，从而实现转动安装在机构支架0上。
如图11和14所示，所述操作机构还包括作用于跳扣件12的辅助弹簧19，在锁扣件13和跳扣件12解除搭扣配合后，主弹簧9和辅助弹簧19用于驱动跳扣件12向同一方向转动，也即是，主弹簧9和辅助弹簧19均向跳扣件12施加作用力，两个作用力均使跳扣件12向同一方向转动，跳扣件12转动而远离锁扣件13，并且沿脱扣方向转动至脱扣位置后，与摇臂5限位配合使跳扣件12与摇臂5保持相对静止。所述主弹簧9和辅助弹簧19配合，显著提高操作机构的瓦解速度和脱扣速度，减少操作机构的动作时间，而且主弹簧9和辅助弹簧19均可以通过跳扣件12、第二连杆15、第一连杆8和转轴11驱动动触头机构 向断开位置转动，有助于提高动触头机构与静触头的分断效率，提高隔离开关的分断能力。
进一步的，所述跳扣件15中部转动设置在机构支架0上，一端与锁扣件13搭扣配合，另一端与辅助弹簧19相连。进一步的，所述辅助弹簧19一端与跳扣件12相连，另一端固定设置在机构支架0上。进一步的，所述机构支架0设有支架挂簧部，跳扣件12设有跳扣件挂簧部，辅助弹簧19两端分别连接至支架挂簧部和跳扣件挂簧部。进一步的，所述支架挂簧部和/或跳扣件挂簧部为挂钩或挂孔。
如图14所示，所述操作机构不设置复位轴17，摇臂5还包括复位部5-3，复位部5-3设置在摇臂腿5-1上，跳扣件12包括复位凸起12-1；所述操作机构脱扣后，摇臂5在脱扣位置，其向分闸位置摆动时，同步通过复位部5-3抵压复位凸起12-1使跳扣件12复位至与锁扣件13恢复搭扣配合。进一步的，所述复位部5-3为与摇臂腿5-1弯折相连的复位板，复位凸起12-1包括复位凸起弧形面，复位板抵压复位凸起弧形面使跳扣件12复位至与锁扣件13恢复搭扣配合。进一步的，所述跳扣件12通过复位凸起12-1与第一连杆8转动相连。
如图14所示，所述操作机构不设置单独的止动件16，操作机构的第五轴5s作为止动件16。
如图14所示，为本实施例旋转隔离开关的操作机构的一种布局方式：所述机构支架0的两块侧板之间形成安装空间；所述跳扣件12、主弹簧9、第二连杆15、第一连杆8、锁扣件13、再扣件14、转轴11以及辅助弹簧19均位于安装空间内；在所述安装空间的第一方向上，安装空间的两端分别为第一端和第二端，摇臂5的摇臂横梁5-0位于安装空间的第一端外侧，转轴11位于安装空间的第二端内；在所述安装空间的第二方向上，安装空间的两端分别为第三端和第四端，锁扣件13和再扣件14位于安装空间的第三端内，辅助弹簧19位于安装空间的第四端内，跳扣件12从第三端延伸至第四端；所述第一方向和第二方向均平行于机构支架0的两块侧板且第一方向和第二方向相交。进一步的，在所述安装空间的第二方向上，缓冲件41设置在第四端内，转轴11位于缓冲件41和摇臂5的摇臂横梁5-0之间；所述跳扣件止动轴设置在第四端内，跳扣件止动轴和辅助弹簧19，在安装空间的第一方向上，位于跳扣件12两侧。所述操作机构布局合理紧凑，有利于减少所述空间。具体的，所述第一方向为图14的左右方向，第二方向为图14的上下方向。
