结合图2a、图2b和图2d所示，滑动板202上具有第一驱动槽221、第二驱动槽222、解锁槽223和联锁槽224。主轴203上安装有第一悬臂231和第二悬臂232。第一悬臂231具有分叉的第一驱动杆233和联锁杆234，第二悬臂232具有分叉的第二驱动杆235和解锁杆236。如图所示，第一驱动槽221和联锁槽224沿一直线排列，并且第一驱动槽221和联锁槽224与第一悬臂上的第一驱动杆233和联锁杆234形成驱动耦合。第一驱动杆233和联锁杆234从第一悬臂231的张开角度与第一驱动槽221和联锁槽224的间隔相匹配。在动作时，第一驱动杆233与第一驱动槽221配合，联锁杆234与联锁槽224配合。第二驱动槽222和解锁槽223也是沿一直线排列，并且第二驱动槽222和解锁槽223与第二悬臂上的第二驱动杆235和解锁杆236形成驱动耦合。第二驱动杆235和解锁杆236从第二悬臂232的张开角度与第二驱动槽222和解锁槽223的间隔相匹配。在动作时，第二驱动杆235与第二驱动槽222配合，解锁杆236与解锁槽223配合。在图示的实施例中，滑动板202上还具有导向槽225，导向槽225在滑动板移动时进行导向，滑动板202沿着导向槽225移动。
结合图2b、图2c和图2d所示，主轴203的两端安装有传动齿轮237。托板204的底部呈圆形且具有传动齿241，传动齿241与传动齿轮237咬合，主轴203转动带动托板204转动。由于主轴203和托板204是通过齿轮咬合的方式传动，因此主轴203和托板204的转动方向是相反的。参考图2c所 示，托板204的内侧壁向顶部延伸形成联锁板242，托板的顶部的内侧端形成驱动凹槽243，托板的顶部的外侧端形成连接面244，托板的外侧壁的顶部呈凸角，形成退出驱动部245。
图3揭示了根据本发明的一实施例的电开关装置中锁紧机构的结构图。驱动机构驱动锁紧机构使得锁紧机构驱动电连接装置的夹紧机构，电连接装置夹紧或者放松断路器本体的母排。参考图3所示，锁紧机构包括：锁紧齿轮301、锁紧传动轴302和锁紧齿条303。锁紧齿轮301安装在抽屉装置上，锁紧齿轮301能转动。锁紧传动轴302连接锁紧齿轮301和电连接装置102的夹紧机构。在图示的实施例中，锁紧传动轴302与锁紧齿轮301同轴，锁紧传动轴302和锁紧齿轮301同步转动。锁紧齿轮301转动，锁紧传动轴302跟随锁紧齿轮301转动，锁紧传动轴302连接到电连接装置的夹紧机构，锁紧传动轴302带动夹紧机构夹紧或者放松断路器本体的母排。电连接装置的夹紧机构夹紧或者放松断路器母排的结构在诸如CN111403939A、CN111403938A、CN211017487U、CN211045800U的专利申请及专利中描述。锁紧齿条303形成在滑动板202上，锁紧齿条303从滑动板202的内侧端开始朝向外侧延伸。滑动板向内侧移动，锁紧齿条303与锁紧齿轮301接触并咬合，带动锁紧齿轮按夹紧方向转动，通过锁紧传动轴302带动夹紧机构夹紧断路器本体的母排。滑动板向外侧移动，带动锁紧齿轮301按放松方向转动，通过锁紧传动轴302带动夹紧机构放松断路器本体的母排。滑动板202继续向外侧移动，由于锁紧齿轮301的位置是固定的，在滑动板202向外侧移动足够的距离之后，锁紧齿条303与锁紧齿轮301脱离，锁紧齿轮301不再转动，电连接装置的夹紧机构也就不再动作。在一个实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式，与之相对应的，电连接装置具有足够大的夹紧行程，以满足在分离位置和试验位置下，母排尚未插入电连接装置时，电连接装置空转的需求。具体而言，滑动板202向外侧外侧移动到位后，锁紧齿条303与锁紧齿轮301可以仍然处于接触咬合状态，在该实施例中，需要电连接装置102的夹紧行程足够大，在分离位置和试验位置滑动板的移动过程中，电连接装置102空转夹紧但是依旧有足够的空间间距，使得断路器本体母排151进入电连接装置102的过程中不受到夹紧力。该种实施例的优点是，锁紧齿条303与锁紧齿轮301保持咬合而使得整个系统一直处于耦合状态，避免了因零部件之间的装配间隙而影响重新咬合。该种实 施例具有更加稳定的工作性能。
联锁机构包括：抽屉联锁件401、抽屉推杆402和联锁板242。图4揭示了根据本发明的一实施例的电开关装置中联锁机构的抽屉联锁件的结构图。抽屉联锁件401安装在抽屉装置上，抽屉联锁件401的安装位置靠近抽屉装置101的外侧。参考图4所示，抽屉联锁件401的外侧端和内侧端分别形成凸出的联锁部411和412，抽屉联锁件的中间形成凹进的释放部413。抽屉推杆402可以参考图5，图5揭示了根据本发明的一实施例的电开关装置的整体结构图。抽屉推杆402安装在抽屉装置上，抽屉推杆402位于抽屉联锁件401的内侧，抽屉推杆402的中部通过转轴转动连接到抽屉装置。抽屉推杆的顶部是水平向的联锁杆421，抽屉推杆的底部是倾斜向的触发杆422，抽屉推杆具有联锁位置和释放位置。在联锁位置联锁杆421向下方压下，在释放位置联锁杆421向上方抬起，抽屉推杆具有推杆弹簧(图中未示出)，推杆弹簧的弹簧力使得抽屉推杆朝向释放位置转动。联锁板242由托板204的内侧壁向顶部延伸形成，联锁板242可参考图2c所示。
图5揭示了根据本发明的一实施例的电开关装置的整体结构图。图5去除了抽屉装置和断路器本体，更加清晰地展示了电连接装置102、驱动机构、锁紧机构和连锁机构的结构。由于角度的关系，在图5中锁紧机构中的锁紧齿轮和锁紧传动轴没有被示出，但位于滑动板内侧端的锁紧齿条清晰可见。图5中可见装配完成的驱动轴201、滑动板202、主轴203和托板204。在图5所示的实施例中，驱动机构还包括侧面滑板205，侧面滑板205上具有进入轴销251和退出轴销252，断路器本体安装在侧面滑板205上。侧面滑板205的进入轴销251和退出轴销252与托板204配合，带动断路器本体进入或者退出抽屉装置。图5中展示了抽屉联锁件401和抽屉推杆402位置，抽屉联锁件401和抽屉推杆402与断路器本体上的脱扣杆501配合，脱扣杆501决定断路器本体是否可以合闸。脱扣杆501被锁定，断路器本体不能合闸，脱扣杆501被释放，断路器本体能合闸。
下面分别介绍断路器本体与抽屉装置在四个相对位置的状态。在断路器本体进入抽屉装置的过程中，会依次经过分离位置、试验位置、连接未夹紧位置和连接夹紧位置。
首先是分离位置。在分离位置的要求是断路器本体的母排与电连接装置分离，并且断路器本体不能合闸。图6揭示了根据本发明的一实施例的电开 关装置在分离位置的侧面结构图。图7a和图7b揭示了根据本发明的一实施例的电开关装置的驱动机构在分离位置的结构图。如图7a和7b所示，在分离位置，主轴203位于分离角度，第一驱动杆233位于第一驱动槽221中，第二驱动杆235位于第二驱动槽222中。解锁杆236与解锁槽223互相分离不作用，联锁杆234与联锁槽224也互相分离不作用。结合图6、图7a和图7b，在分离位置，主轴203位于分离角度，托板204也位于分离角度。侧面滑板205的进入轴销251位于托板204的驱动凹槽243中。放置在侧面滑板上的断路器本体位于分离位置。在分离位置，抽屉联锁件401的外侧端的联锁部411压住并锁定脱扣杆501，使得断路器本体不能合闸。在分离位置，锁紧齿轮与锁紧齿条脱离，因此锁紧机构不会动作。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。
然后是试验位置。在试验位置的要求是断路器本体的母排与电连接装置分离，但断路器本体能合闸。试验位置主要是测试电开关装置对于断路器本体的操作功能，试验合闸和分闸的操作，因此需要断路器本体在试验位置能够进行合闸和分闸操作。但试验位置仅是对于断路器本体的操作功能的试验，断路器本体尚未接入到主回路中，所以断路器本体的母排与电连接装置还是分离的。图8揭示了根据本发明的一实施例的电开关装置在试验位置的侧面结构图。图9a和图9b揭示了根据本发明的一实施例的电开关装置的驱动机构在试验位置的结构图。如图9a和9b所示，从分离位置移动到试验位置的过程中，滑动板202在驱动轴201的作用下沿着导向槽225朝向抽屉装置的内侧移动，第一驱动槽221的外侧端推动第一驱动杆233，第二驱动槽222的外侧端推动第二驱动杆235。由于第一悬臂231和第二悬臂232是固定在主轴上，第一驱动杆和第二驱动杆在第一驱动槽和第二驱动槽的推动下移动，带动第一悬臂和第二悬臂移动，带动主轴203转动，使得主轴203从分离角度转动到试验角度。在这个过程中解锁杆与解锁槽不作用，联锁杆与联锁槽也不作用。结合图8、图9a和图9b，从分离位置移动到试验位置，主轴203从分离角度转动到试验角度，通过传动齿轮237与主轴咬合的托板204也被带动而从分离角度转动到试验角度。需要说明的是，因为托板204与主轴203是通过齿轮咬合，因此托板与主轴的转动方向是相反的，主轴顺时针转动时，托板逆时针转动。主轴逆时针转动时，托板顺指针转动。托板的驱动凹槽243 的外侧端推动侧面滑板205的进入轴销251。托板从分离角度转动到试验角度，通过侧面滑板205带动断路器本体从分离位置移动到试验位置。在从分离位置移动到试验位置的过程中，断路器本体向内侧移动，脱扣杆501也向内侧移动而进入到抽屉联锁件401中间的凹进的释放部413。释放部413是向内凹进，因此脱扣杆501被释放，断路器本体能进行合闸操作，满足试验位置的要求。在试验位置，锁紧齿轮与锁紧齿条依旧是脱离的，因此锁紧机构不会动作。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。
接下来是连接未夹紧位置。在连接未夹紧位置的要求是断路器本体的母排与电连接装置接触，电连接装置未夹紧母排，断路器本体不能合闸。从试验位置进入到连接未夹紧位置，断路器本体的母排开始进入电连接装置的区域。但是在母排完全插入电连接装置并且被夹紧之前，主回路需要保持断开的状态，因此在此过程中断路器本体不能合闸。图10揭示了根据本发明的一实施例的电开关装置在连接未夹紧位置的侧面结构图。图11a和图11b揭示了根据本发明的一实施例的电开关装置的驱动机构在连接未夹紧位置的结构图。如图11a和11b所示，从试验位置移动到连接未夹紧位置的过程中，滑动板202在驱动轴201的作用下沿着导向槽225继续朝向抽屉装置的内侧移动。第一驱动槽221的外侧端推动第一驱动杆233直至第一驱动杆233脱出第一驱动槽221(参考图11b)。第二驱动槽222的外侧端推动第二驱动杆235直至第二驱动杆235脱出第二驱动槽222(参考图11b)。这事主轴203转动到连接未夹紧角度。处于连接未夹紧角度的主轴的第一驱动杆和第二驱动杆已经从第一驱动槽和第二驱动槽中脱出。联锁杆234尚未进入到联锁槽224中。而解锁杆236虽然进入到了解锁槽223中，但解锁槽223是一个比较长的槽，因此解锁杆236与解锁槽223在这个位置不作用。于是，在到达连接未夹紧位置后，滑动板与主轴之间暂时不互相作用。结合图10、图11a和图11b，从试验位置移动到连接未夹紧位置，主轴203从试验角度转动到连接未夹紧角度，通过传动齿轮237与主轴咬合的托板204也被带动而从试验角度转动到连接未夹紧角度。在这个过程中，驱动凹槽243的外侧端推动侧面滑板205的进入轴销251，通过侧面滑板205带动断路器本体从试验位置移动到连接未夹紧位置。当主轴和托板都转动到连接未夹紧角度，侧面滑板和断路器本体也抵达连接未夹紧位置后，进入轴销251从驱动凹槽243中 脱出并停留在托板204的连接面244上。连接面244是一个连续的弧面，因此当进入轴销251位于在连接面244上时，托板204的继续转动就不会再推动连接轴销251，也就是说，托板204继续转动，侧面滑板和断路器本体的位置不再移动。从试验位置移动到连接未夹紧位置的过程中，断路器本体向内侧移动，脱扣杆501从抽屉联锁件401的释放部413脱出，重新被抽屉联锁件内侧端的联锁部412压住并锁定，使得断路器本体不能合闸。断路器本体继续向内侧移动，托板204上的联锁板242随托板转动并与抽屉推杆402的触发杆422接触。在联锁板242的作用下，抽屉推杆402克服推杆弹簧的弹簧力，从释放位置转动到联锁位置，抽屉推杆402的联锁杆421向下压。脱扣杆501跟随断路器本体向内侧移动并与抽屉联锁件401分离后，脱扣杆501继续被抽屉推杆402的联锁杆421压下并锁定，断路器本体依旧维持不能合闸的状态。在从试验位置移动到连接未夹紧位置的过程中，锁紧机构有两种实现模式：第一种模式下，从试验位置移动到连接未夹紧位置的过程中，滑动板202和断路器本体向内侧移动，断路器本体的母排逐步进入电连接装置102中，锁紧齿条303与锁紧齿轮301咬合，随着滑动板的移动，锁紧齿条同步带动锁紧齿轮按夹紧方向转动，电连接装置102的夹紧机构开始逐步夹紧断路器本体的母排。在第一种模式中，锁紧齿条303的长度较长，从滑动板的内侧端延伸比较长的距离，当滑动板过了试验位置之后，锁紧齿条就开始与锁紧齿轮咬合，断路器本体的母排进入电连接装置和电连接装置夹紧母排的动作同步进行。第二种模式下，从试验位置移动到连接未夹紧位置，滑动板和断路器本体向内侧移动，断路器本体的母排逐步进入电连接装置中，但锁紧齿条与锁紧齿轮依旧保持脱离。在第二种模式中，锁紧齿条303的长度较短，从滑动板的内侧端延伸比较短的距离，在滑动板抵达连接未夹紧位置之前，锁紧齿条与锁紧齿轮始终是分离的，断路器本体的母排进入电连接装置和电连接装置夹紧母排的动作是分开进行。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。
最后是连接夹紧位置。在连接夹紧位置的要求是断路器本体的母排与电连接装置接触，电连接装置夹紧母排，断路器本体能合闸。连接夹紧位置就是正常使用的位置，断路器本体的母排与电连接装置充分接触并且被夹紧，断路器本体接入到主回路中并正常工作，因此在连接夹紧位置断路器本体要 能够合闸。图12揭示了根据本发明的一实施例的电开关装置在连接夹紧位置的侧面结构图。图13a和图13b揭示了根据本发明的一实施例的电开关装置的驱动机构在连接夹紧位置的结构图。如图13a和13b所示，从连接未夹紧位置移动到连接夹紧位置，滑动板202在驱动轴201的作用下沿着导向槽225继续朝向抽屉装置的内侧移动。此时解锁杆236位于解锁槽223中，由于解锁槽223是一个比较长的槽，在解锁槽223的外侧端接触到解锁杆236之前，滑动板202与主轴203之间并无相互作用，此时滑动板继续向内侧移动的主要作用是使得设置在滑动板内侧端的锁紧齿条303带动锁紧齿轮转动，使得电连接装置夹紧断路器本体的母排。在锁紧到位后，滑动板202移动到了连接夹紧位置，这时解锁槽223的外侧端接触并且推动解锁杆236使得主轴203转动到连接夹紧角度。于此同时，在主轴转动到连接夹紧角度时，联锁杆234进入到联锁槽224中，但联锁杆234与联锁槽224并不作用。联锁杆234进入到联锁槽224中是为了断路器本体退出时，可以利用联锁杆234和联锁槽224来使得断路器本体重新被锁定不能合闸。结合图12、图13a和图13b，从连接未夹紧位置移动到连接夹紧位置后，主轴203从连接未夹紧角度转动到连接夹紧角度，通过传动齿轮237与主轴咬合的托板204也被带动而从连接未夹紧角度转动到连接夹紧角度。在这个过程中，侧面滑板205的进入轴销251在托板204的连接面244上滑移，托板204与进入轴销251之间不作用，因此侧面滑板和断路器本体的位置都不移动。从连接未夹紧位置移动到连接夹紧位置的过程中，托板204从连接未夹紧角度转动到连接夹紧角度，虽然与侧面滑板不再作用，但联锁板242随托板204转动并与抽屉推杆402的触发杆422分离。这时抽屉推杆402在推杆弹簧的作用下重新从联锁位置转动到释放位置，抽屉推杆402的联锁杆421释放脱扣杆501，断路器本体能合闸。对于锁紧机构来说，无论是使用前述的哪一种模式(锁紧齿条长或者锁紧齿条短)，在从连接未夹紧位置移动到连接夹紧位置的过程中，锁紧齿条都会与锁紧齿轮咬合。在这个过程中，断路器本体不移动，断路器本体的母排完全进入电连接装置中，滑动板202继续向内侧移动，锁紧齿条303与锁紧齿轮咬合，带动锁紧齿轮继续按夹紧方向转动，夹紧机构夹紧断路器本体的母排。
图14a、图14b、图14c和图14d揭示了在不同的位置下滑动板和主轴的配合关系。进一步展示了滑动板202上的第一驱动槽221、第二驱动槽222、 解锁槽223和联锁槽224与主轴的第一悬臂231、第二悬臂232上的第一驱动杆233、联锁杆234、第二驱动杆235和解锁杆236在断路器本体推进过程中的配合过程。在分离位置，参考图14a所示，主轴位于分离角度，第一驱动杆位于第一驱动槽中(由于角度关系第一驱动杆和第一驱动槽在图14a中被遮挡)，第二驱动杆235位于第二驱动槽222中，解锁杆236与解锁槽223分离并且不作用，联锁杆234与联锁槽224分离并且不作用。从分离位置移动到试验位置，参考图14b所示，滑动板202朝向抽屉装置的内侧移动，图14a、图14b、图14c和图14d中箭头所指的方向为滑动板202的移动方向。第一驱动槽的外侧端推动第一驱动杆(由于角度关系第一驱动杆和第一驱动槽在图14b中被遮挡)，第二驱动槽222的外侧端推动第二驱动杆235，使得主轴转动到试验角度，解锁杆236与解锁槽223不作用，联锁杆234与联锁槽224也不作用。从试验位置移动到连接未夹紧位置，参考图14c所示，滑动板202继续朝向抽屉装置的内侧移动，第一驱动槽的外侧端推动第一驱动杆直至第一驱动杆脱出第一驱动槽(由于角度关系第一驱动杆和第一驱动槽在图14c中被遮挡)，第二驱动槽222的外侧端推动第二驱动杆235直至第二驱动杆脱出第二驱动槽。使得主轴转动到连接未夹紧角度。此时解锁杆236进入解锁槽223，但解锁槽223是一个比较长的槽，所以解锁杆236与解锁槽223不作用，联锁杆234还没有进入联锁槽224所以联锁杆234与联锁槽224也不作用。从连接未夹紧位置移动到连接夹紧位置，参考图14d所示，滑动板202继续朝向抽屉装置的内侧移动，解锁槽223的外侧端接触解锁杆236并且推动解锁杆236使得主轴转动到连接夹紧角度。主轴转动到连接夹紧角度时，联锁杆234进入到联锁槽224但联锁杆234与联锁槽224并不作用。联锁杆234进入到联锁槽224是为了在退出的时候联锁槽224的内侧端可以作用于联锁杆234使得断路器本体的脱扣杆被锁定而不能合闸。
断路器本体退出抽屉装置的过程和上述的过程正好相反，依次经过连接夹紧位置、连接未夹紧位置、试验位置和分离位置。
在连接夹紧位置，参考图12、图13a和图13b。主轴203位于连接夹紧角度，联锁杆234位于联锁槽224中，解锁杆236位于解锁槽223中，第一驱动杆与第一驱动槽不作用，第二驱动杆与第二驱动槽不作用。在连接夹紧位置，主轴203位于连接夹紧角度，托板204同样位于连接夹紧角度，侧面滑板205的进入轴销251位于托板204的连接面244上，侧面滑板205的退 出轴销252与托板204也不接触。在连接夹紧位置，联锁板242与抽屉推杆402的触发杆422分离，抽屉推杆402在推杆弹簧的作用下位于释放位置，联锁杆421向上抬起，脱扣杆501被释放，断路器本体能合闸。
从连接夹紧位置移动到连接未夹紧位置，参考图10、图11a和图11b。滑动板202在驱动轴201的作用下沿导向槽225朝向抽屉装置的外侧移动，联锁槽224的内侧端推动联锁杆234直至联锁杆234脱出联锁槽224，使得主轴203转动到连接未夹紧角度。在主轴转动到连接未夹紧角度之前，解锁杆236仅是位于解锁槽223中但解锁杆236与解锁槽223不作用。第一驱动杆与第一驱动槽不作用，第二驱动杆与第二驱动槽不作用。从连接夹紧位置移动到连接未夹紧位置，主轴203从连接夹紧角度转动到连接未夹紧角度，通过传动齿轮237与主轴咬合的托板204也被带动而从连接夹紧角度转动到连接未夹紧角度。进入轴销251在托板204的连接面244上滑移，退出轴销252与托板204还没有接触，托板204与进入轴销251以及退出轴销252均不作用，侧面滑板205和断路器本体都不移动。从连接夹紧位置移动到连接未夹紧位置，侧面滑板和断路器本体虽然不移动，但联锁板242随托板204转动并与抽屉推杆402的触发杆422接触，抽屉推杆402在联锁板242的作用下克服推杆弹簧的弹簧力，从释放位置转动到联锁位置，抽屉推杆402的联锁杆421压下并锁定脱扣杆501，断路器本体不能合闸。从连接夹紧位置移动到连接未夹紧位置，侧面滑板和断路器本体不移动，滑动板向外侧移动，锁紧齿条303与锁紧齿轮咬合，锁紧齿条303带动锁紧齿轮按放松方向转动，使得夹紧机构放松断路器本体的母排。在使用较短的锁紧齿条的模式下(对应前述的第二种模式)，在抵达连接未夹紧位置时，锁紧齿条与锁紧齿轮脱离，电连接装置放松母排和断路器本体的母排退出电连接装置的动作是分开进行的。在使用较长的锁紧齿条的模式下(对应前述的第一种模式)，在抵达连接未夹紧位置时，锁紧齿条与锁紧齿轮依旧咬合尚未脱离，电连接装置放松母排和断路器本体的母排退出电连接装置的动作是同步进行的。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。如果是始终咬合的形式，那么锁紧齿条与锁紧齿轮并不脱离。
从连接未夹紧位置到试验位置，参考图8、图9a和图9b。滑动板202在驱动轴201的作用下沿导向槽225朝向抽屉装置的外侧移动，解锁槽223 的内侧端推动解锁杆236，使得主轴203从连接未夹紧角度向试验角度转动。在此过程中，第一驱动杆233进入到第一驱动槽221中，第二驱动杆235进入到第二驱动槽222中。解锁槽223的内侧端持续推动解锁杆236直至解锁杆236脱出解锁槽233，然后，第一驱动槽221的内侧端继续推动第一驱动杆233，第二驱动槽222的内侧端继续推动第二驱动杆235，使得主轴203持续转动直到转动到试验角度。从连接未夹紧位置到试验位置，主轴203从连接未夹紧角度转动到试验角度，通过传动齿轮237与主轴咬合的托板204也被带动而从连接未夹紧角度转动到试验角度。托板204的退出驱动部245接触并推动退出轴销252，使得侧面滑板205带动断路器本体向外侧移动，同时进入轴销251从托板的连接面进入到驱动凹槽243中。托板204继续转动，退出轴销252与托板的退出驱动部245分离，接下来由托板的驱动凹槽243的内侧端推动进入轴销251，使得侧面滑板205带动断路器本体继续向外侧移动至试验位置。在另一个实施例中，也可以始终由退出驱动部245一直推动退出轴销252直至试验位置，而进入轴销251并不参与退出的过程。从连接未夹紧位置到试验位置的过程中，断路器本体向外侧移动，脱扣杆501与抽屉推杆402的联锁杆421分离但继续被抽屉联锁件401内侧端的联锁部413压下并锁定，断路器本体不能合闸。断路器本体移动到试验位置，脱扣杆501进入抽屉联锁件401中间的凹进的释放部413，脱扣杆501被释放，断路器本体能合闸。从连接未夹紧位置到试验位置，滑动板和断路器本体向外侧移动，断路器本体的母排逐步退出电连接装置。在使用较长的锁紧齿条的模式下(对应前述的第一种模式)，锁紧齿条与锁紧齿轮依旧咬合，带动锁紧齿轮继续按放松方向转动，夹紧机构继续放松，滑动板和断路器本体向外侧移动到试验位置，断路器本体的母排与电连接装置分离，锁紧齿条与锁紧齿轮脱离。在使用较短的锁紧齿条的模式下(对应前述的第二种模式)，锁紧齿条与锁紧齿轮在连接未夹紧位置就已经脱离，从连接未夹紧位置到试验位置，滑动板和断路器本体向外侧移动，断路器本体的母排逐步退出电连接装置。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。如果是始终咬合的形式，那么锁紧齿条与锁紧齿轮并不脱离。
从试验位置到分离位置，参考图6、图7a和图7b。滑动板202在驱动轴201的作用下沿导向槽225朝向抽屉装置的外侧移动，第一驱动槽221的 内侧端推动第一驱动杆233，第二驱动槽222的内侧端推动第二驱动杆235，使得主轴转动到分离角度，第一驱动杆233保持在第一驱动槽221中，第二驱动杆235保持在第二驱动槽222中，为下一次的进入过程做好准备。从试验位置到分离位置，主轴从试验角度转动到分离角度，通过传动齿轮237与主轴咬合的托板204也被带动而从试验角度转动到分离角度，驱动凹槽243的内侧端推动进入轴销251，使得侧面滑板205和断路器本体向外侧移动至分离位置。在另一个实施例中，也可以始终由退出驱动部245一直推动退出轴销252直至分离位置，而进入轴销251并不参与退出的过程。从试验位置到分离位置，断路器本体向外侧移动，脱扣杆501从抽屉联锁件401的释放部413脱出，被抽屉联锁件外侧端的联锁部411锁定，断路器本体不能合闸。从试验位置到分离位置，锁紧齿轮与锁紧齿条脱离，锁紧机构不动作。如前面所介绍的，在电连接装置具有足够大的夹紧行程的情况下，在一些实施例中，也可以将锁紧齿条和锁紧齿轮配置成始终咬合的形式。如果是始终咬合的形式，那么锁紧齿条与锁紧齿轮并不脱离。
本发明的电开关装置具有新结构的电连接装置，该电连接装置可以根据需要配置大的夹紧力来夹紧本体母排，使得电器装置的整体接触电阻大幅度减小，尤其在长期的使用中大幅度降低功耗，大大节约使用成本，电器装置的额定电流越高，这种优势则更加显著。另一方面，接触电阻的减小，使得产品的温升降低，电器装置的发热减小，不需要考虑大的散热空间，有力于减小产品的尺寸，提高长期使用的可靠性。本发明的电开关装置提供与该电连接装置配套的抽屉装置、驱动机构、锁紧机构和联锁机构，结合该电连接装置的特点，本发明的电开关装置具有分离位置、试验位置、连接未夹紧位置和连接夹紧位置四个工作位置，确保电开关装置的可操作性和安全性。另一方面，断路器本体母排进入电连接装置以及两者之间的电接触夹紧分成连接未夹紧和连接夹紧两个过程，断路器本体运动的操作力和电连接装置夹紧力相互不受影响，大大减小了断路器本体进入抽屉装置整个过程的操作力，两种力之间不需要进行相互妥协。
上述实施例是提供给熟悉本领域内的人员来实现或使用本发明的，熟悉本领域的人员可在不脱离本发明的发明思想的情况下，对上述实施例做出种种修改或变化，因而本发明的保护范围并不被上述实施例所限，而应该是符合权利要求书提到的创新性特征的最大范围。
