具体实施方式
以下结合附图1至20给出的实施例，进一步说明本发明的断路器的电动操作装置的具体实施方式。本发明的断路器的电动操作装置不限于以下实施例的描述。
如图1-5所示，一种断路器的电动操作装置，其壳体1的一个侧壁作为操作面11设有第一滑槽101，第一滑槽101与断路器的手柄5正对，壳体1内安装有驱动断路器的手柄5分闸、合闸的驱动件，壳体1内安装有滑动杆102，驱动件安装于滑动杆102上，所述驱动件可从第一滑槽101中伸出壳体1外并在壳体1内的传动机构的操作下沿第一滑槽101运动用于操作断路器手柄5分闸或合闸。
所述驱动件包括合闸操作部31a和分闸操作部31b，如图3所示，在初始状态时，驱动件的合闸操作部31a和分闸操作部31b之间预留有空间，合闸操作部31a位于分闸操作部31b的下方，断路器的手柄5伸入该空间内。如图4所示，当需要使断路器合闸时，传动机构驱动合闸操作部31a沿第一滑槽101向上运动，推动断路器的手柄5向上合闸；如图5所示，当需要使断路器分闸时，传动机构驱动分闸操作部31b向下运动，推动断路器的手柄5向下分闸。需要指出的是，上下设置是相对的，显然也可以，分闸操作部31b位于合闸操作部31a的下方，分闸操作部31b向上运动推动断路器的手柄5分闸。优选的，在初始状态时，即不进行分合闸操作时，合闸操作部31a和分闸操作部31b均不会接触到断路器的手柄5，并且在合闸驱动件或分闸驱动件驱动断路器的手柄动作后能够自动恢复到初始状态等待下一次的指令。在合闸驱动件与分闸驱动件之间预留的空间使合闸驱动件、分闸驱动件在初始状态时不与手柄5接触，当合闸驱动件或分闸驱动件驱动手柄5动作后能恢复初始状态，避免合闸驱动件或分闸驱动件产生误动作，造成断路器的损坏。具体为，当合闸驱动件操作断路器的手柄5合闸后恢复至初始状态，分闸驱动件操作断路器的手柄5分闸后恢复至初始状态，这样就可以避免合闸驱动件干扰分闸驱动件的分闸动作，分闸驱动件干扰合闸驱动件的合闸动作，一种实施方式为在传动机构内设置有位置识别开关，在位置识别开关被触发后通过控制电路控制传动机构动作操作合闸驱动件或分闸驱动件回到初始位置。
这种设置在断路器手柄5正面的电动操作装置，而非传统的设置的断路器的侧壁，可以应用于横向空间有限的机柜中，也可以避免在操作断路器的手柄5过程中产生倾斜，引起断路器触头不同步，或者避免需给每极断路器单独配置电动操作装置。
作为一种实施例，所述的合闸操作部31a和分闸操作部31b的宽度可以根据需要加宽，同时驱动多极断路器的手柄5同时动作。
优选的，作为一种实施例，如图3所示，在电动操作装置上还设有移动装置6，与操作面11相对的侧壁作为连接面12安装有用于位移的移动装置6，其连接面12如图2所示，电动操作装置通过移动装置6安装在移动轨道(图中未示出)上，移动装置6能够带动电动操作装置沿移动轨道移动分别与不同的断路器的手柄5对应，以驱动不同的断路器做不同的合闸和分闸动作。
作为一种实施例，如图6、7所示，在断路器的电动操作装置的壳体1内设有支架，所述支架将壳体1内的空间划分为驱动空间和传动空间；所述支架具体包括间隔设置的第一支架103和第二支架104，第一支架103与第二支架104 之间的空间作为安装传动装置的传动空间，第一支架103与操作面11之间的空间作为安装驱动件的驱动空间。优选的在驱动空间内安装有滑动杆102，驱动件滑动安装于滑动杆102上并在传动机构的操作下在滑动杆102上沿着第一滑槽101运动。第一支架103、第二支架104将壳体1内空间划分出两个相对独立的部分，为传动机构和驱动件提供工作区，避免因各功能部件的相互干扰而造成性能不稳定。
优选的，传动机构包括电机201和与电机201连接的齿轮组，所述齿轮组包括分合闸输出齿轮，分合闸输出齿轮设有传动轴，所述驱动件上设有与传动轴配合的联动槽，电机201驱动齿轮组转动，通过分合闸输出齿轮的传动轴与驱动件的联动槽的配合，使驱动件在滑动杆102上滑动以操作断路器的手柄5合闸或分闸。所述齿轮组安装在第一支架103与第二支架104之间的传动空间。
优选的，所述分合闸输出齿轮的传动比周期性变化，为驱动件提供周期性变化的驱动力和动作速度，分合闸输出齿轮的周期性传动比在合闸前期为驱动件提供较大的驱动力，在合闸后期为驱动件提供较大的合闸速度，以此减少触头的烧损或断路器的故障。一种优选方案为，分合闸输出齿轮优选为椭圆齿轮，这样可以设置合适的传动力和杠杆比，使驱动件在合闸、分闸中获得周期性变化的驱动力和动作速度，避免产生触头烧损或断路器故障，采用这种非圆齿轮组成的齿轮副能够实现周期变化的传动比，结构紧凑、刚性较好且能保证传动较为平稳。显然，分合闸输出齿轮也可以为圆形齿轮，但其无法获得周期性传动比。
在图10、11的实施例中，分合闸输出齿轮包括合闸输出齿轮205和分闸输出齿轮206，分合闸输出齿轮上的传动轴包括设置于合闸输出齿轮205上的合闸传动轴205a和设置于分闸输出齿轮206上的分闸传动轴206a，合闸传动轴205a用于操作驱动件的合闸操作部31a使断路器的手柄5合闸，分闸传动轴206a用于操作驱动件的分闸操作部31b使断路器的手柄5分闸。优选的，合闸输出齿轮205和分闸输出齿轮206彼此啮合，可以同时驱动控制。
所述合闸输出齿轮205和分闸输出齿轮206优选为由金属材料制作的椭圆齿轮，椭圆齿轮的节曲线为椭圆或高阶椭圆，由于椭圆齿轮的每个轮齿所对应的圆心角大小不总是相等，因而使合闸输出齿轮205与分闸输出齿轮206啮合转动过程中做非匀速转动并且这种非匀速转动呈现周期性的转速变化，根据这一特点设计合适的传动力和杠杆比，使合闸操作部31a在合闸前期能够获得较大的合闸驱动力，在合闸后期获得较快的合闸速度。在合闸前期，即从合闸开始时到快要合闸这一时段，分闸输出齿轮206的椭圆长边与合闸输出齿轮205的椭圆短边接触配合，使合闸操作部31a获得较大的合闸驱动力；在合闸后期时，即快要合闸的时候到合闸完全合闸这一时段，分闸输出齿轮206的椭圆短边与合闸输出齿轮205的椭圆长边接触配合，使合闸操作部31a获得较快的合闸速度；在转动过程中，其中心距固定保证合闸输出齿轮205和分闸输出齿轮206时刻保持良好的啮合，与此同时，传动力和杠杆与断路器的动作过程配合，使合闸瞬间动作快，即在动触头与静触头接触的瞬间增大合闸前期的合闸力。合闸输出齿轮205和分闸输出齿轮206采用这种非圆齿轮组成的齿轮副能够实现周期变化的传动比，结构紧凑、刚性较好且能保证传动较为平稳；金属材料的椭圆齿轮利于延长使用寿命。显然，合闸输出齿轮205和分闸输出齿轮206也可以均圆形齿轮，但其无法获得周期性传动比。
具体的，所述齿轮组还包括一级齿轮202、二级齿轮203和三级齿轮204；所述电机201通过蜗杆与一级齿轮202啮合，一级齿轮202与二级齿轮203啮合，二级齿轮203与三级齿轮204啮合，三级齿轮204安装有分合闸输出齿轮；如图8、10和11所示，所述三级齿轮204设置有合闸输出齿轮205和分闸输出 齿轮206，所述合闸输出齿轮205与分闸输出齿轮206彼此啮合，合闸输出齿轮205和三级齿轮204由同一转动轴带动，合闸输出齿轮205的转动轴为偏心设置，即合闸输出齿轮205的转动轴并非设置在合闸输出齿轮205的中心，分闸输出齿轮206与合闸输出齿轮205啮合，分闸输出齿轮206的转动轴为偏心设置，即分闸输出齿轮206的转动轴并非设置在分闸输出齿轮206的中心，合闸输出齿轮205上设有合闸传动轴205a，分闸输出齿轮206上设有分闸传动轴206a，偏心设置使得两个椭圆齿轮的转动中心保持一定距离。当然，也可以三级齿轮204与分闸输出齿轮206同一转动轴带动，由分闸输出齿轮206驱动合闸输出齿轮205转动。
如图21、22所示，在传动机构还包括一个控制齿轮207和多个位置识别开关，所述控制齿轮207上设有一个凸起的触发台207a，多个位置识别开关固定安装于壳体1内，且间隔设置在与控制齿轮207同轴的圆周上，优选位置为靠近第二支架104的一侧(第二支架104参见图6、7)，所述多个位置识别开关分别用于与触发台207a相配合提供位置信号，控制电机的正转，反转和停止转动。所述多个位置识别开关包括初始位置识别开关208a、合闸位置识别开关208b和分闸位置识别开关208c；所述控制齿轮207与分闸输出齿轮206同一转动轴安装，分闸输出齿轮206转动带动控制齿轮207转动。所述电机201依次驱动合闸输出齿轮205、分闸输出齿轮206和控制齿轮207转动。
合闸过程：当电机201在一级齿轮202、二级齿轮203、三级齿轮204的传动下带动合闸输出齿轮205向合闸方向转动，以合闸输出齿轮逆时针转动为例(参见图22的方向)，此时分闸输出齿轮206、控制齿轮207及触发台207a均为顺时针转动(参见图21的方向为逆时针转动)，触发台207a从初始位置识别开关208a向合闸位置识别开关208b方向转动，合闸输出齿轮205通过合闸传动轴205a使合闸驱动件的合闸操作部31a操作断路器的手柄5合闸，当触发台207a触发合闸位置识别开关208b时，控制电机201反向转动向分闸方向转动，当触发台207a触发初始位置识别开关208a时，合闸操作部31a被控制回到初始位置，电机201停止转动。
分闸过程：当电机201在一级齿轮202、二级齿轮203、三级齿轮204的传动下带动合闸输出齿轮205向分闸方向转动，以合闸输出齿轮205顺时针转动为例(参见图22的方向)，此时分闸输出齿轮206、控制齿轮207及触发台207a均为逆时针转动(参见图21的方向为顺时针转动)，触发台207a从初始位置识别开关208a向分闸位置识别开关208c方向转动，分闸输出齿轮206向分闸方向转动且通过分闸传动轴206a使分闸操作部31b操作断路器的手柄5分闸，当触发台207a触发分闸位置识别开关208c，控制电机201反向转动向合闸方向转动，当触发台207a触发初始位置识别开关208a时，分闸操作部31b被控制回到初始位置。
本发明通过多个位置识别开关提供合闸、分闸和初始位置的到位信号，控制电机的正转和反转，位置识别开关和控制电机201可以分别与控制电路连接，控制电路可以通过电路实现，也可以通过单片机实现，控制电路可以设置在壳体1内，也可以设置在客体1外，通过远程方式控制。
作为一种实施，所述传动机构上设有传动轴，所述驱动件包括合闸驱动件和分闸驱动件，所述合闸驱动件和分闸驱动件分别设有合闸操作部31a和分闸操作部31b，所述合闸驱动件和分闸驱动件分别设有联动槽，两者的联动槽设有方向相反的敞口用于周期性与传动机构的传动轴配合、分离。优选的，驱动件包括与传动机构连接的联动件，在联动件上设置联动槽用于与传动轴连接。
所述驱动件的联动槽能将分合闸输出齿轮的圆周运动转化为直线运动，在联动槽与传动轴的配合下，驱动件在第一滑槽101内做直线运动，驱动件的合 闸操作部31a、分闸操作部31b分别操作断路器的手柄5合闸、分闸，驱动件的直线运动优选沿滑动杆102进行。具体的，如图8所示，合闸驱动件的联动槽为第一联动槽30a，分闸驱动件的联动槽为第二联动槽30c，当传动轴与合闸驱动件上的第一联动槽30a配合时，传动轴与分闸驱动件的第二联动槽30c分离防止分闸驱动件产生误动作；当传动轴与分闸驱动件的第二联动槽30c配合时，传动轴与合闸驱动件的第一联动槽30a分离防止合闸驱动件产生误动作。
具体的，如图8、13、15所示，传动轴包括合闸传动轴205a和分闸传动轴206a，第一联动槽30a与第二联动槽30c均包括一个封闭端和一个敞开端，第一联动槽30a的封闭端与合闸传动轴205a配合带动第一联动件运动，第一联动槽30a的敞开端用于使合闸传动轴205a在合闸完毕后能够转出以此实现与第一联动件的分离，防止合闸操作部31a在分闸时产生误动作；同理，第二联动槽30c的封闭端与分闸传动轴206a配合带动第二联动件运动，第二联动件的敞开端用于使分闸传动轴206a在分闸完毕后能够转出以此实现与第二联动件的分离，防止分闸操作部31b在合闸时产生误动作。
具体的如图7、8所示，所述驱动件包括联动件和由联动件带动的操作件，传动机构与联动件连接，联动件安装在滑动杆102上，操作件与联动件联动，在联动件上设置联动槽用于与传动轴连接，在操作件上设有合闸操作部31a和分闸操作部31b。所述联动件具体包括第一联动件和第二联动件，第一联动件设有周期性与合闸传动轴205a配合的第一联动槽30a，第二联动件设有周期性与分闸传动轴206a配合的第二联动槽30c；操作件包括设有合闸操作部31a的合闸件和分闸操作部31b的分闸件。优选的，所述联动件与操作件之间设有弹性的缓冲件4，所述弹性的缓冲件4用于吸收分合闸余量，防止合闸操作部31a和分闸操作部31b对手柄5进行硬冲击，使手柄5不能准确推到位甚至被折断。当然，弹性的缓冲件4可以都不设置，或者可以仅设置于合闸驱动件上，分闸驱动件上可以省略。
具体如图12、14所示，所述驱动件包括设有合闸操作部31a的合闸驱动件和设有分闸操作部31b的分闸驱动件，合闸件和分闸件作为被联动件带动的操作件。具体的，所述合闸驱动件包括第一联动件和合闸件，第一联动件安装在滑动杆102上，合闸件安装在滑动杆102上且与第一联动件联动，第一联动件上设有与合闸传动轴205a配合的第一联动槽30a，合闸件上设置有用于操作断路器的手柄5的合闸操作部31a，第一联动件与合闸件之间优选的设置有弹性的缓冲件4；分闸驱动件包括第二联动件和分闸件，第二联动件安装在滑动杆102上，分闸件安装在滑动杆102上且与第二联动件联动，第二联动件上设有与分闸传动轴206a配合的第二联动槽30c，分闸件上设置有用于操作断路器的手柄5的分闸操作部31b，第二联动件与分闸件之间优选的设置有弹性的缓冲件4。
合闸驱动件与分闸驱动件彼此独立设置，合闸驱动件、分闸驱动件分别由传动机构带动用于操作断路器的手柄5合闸、分闸。如图6所示，在合闸驱动件与分闸驱动件之间设有压缩弹簧7，所述压缩弹簧7用于辅助配合合闸驱动件与分闸驱动件的复位，同时也能减少合闸驱动件与分闸驱动件两者配合时的间隙影响；合闸驱动件在合闸过程中所做的直线运动使压缩弹簧7形变蓄能，当合闸完毕后，压缩弹簧7的弹力为合闸驱动件回到初始位置提供辅助驱动力；同理，分闸驱动件在分闸过程中所做的直线运动使压缩弹簧7形变蓄能，压缩弹簧7的弹力为分闸驱动件回到初始位置提供辅助驱动力。优选的在合闸驱动件与分闸驱动件两者之间的滑动杆102上套设有压缩弹簧7，既可以作为压缩弹簧7也可以为在第一联动件与第二联动件的复位提供驱动力，保证复位速度。
如图13所示，第一联动件由第一联动壁301、第三联动壁303和第二联动壁302依次连接形成敞口朝向第一滑槽101的U形结构，相对的第一联动壁301 和第二联动壁302上设有供滑动杆102穿过的通孔，第一联动壁301上设有用于连接合闸件的连接槽30b；在第三联动壁303上设有第一联动槽30a，第一联动槽30a的内径大致相等，第一联动槽30a具有一个封闭端和一个敞开端，第一联动槽30a包括连通的第一平直段和第一圆弧段，第一平直段垂直于滑动杆102，第一圆弧段呈四分之一圆弧状，所述封闭端位于第一平直段端部，第一平直段平行于第一联动壁301，敞开端位于第一圆弧段端部，其敞口设置于第二联动壁302与第三联动壁303的连接处，当电机201转动驱动传动机构的合闸输出齿轮205向合闸方向转动时，合闸传动轴205a从第一联动槽30a的敞开端转入第一联动槽30a，且沿第一联动槽30a转动。
如图12所示，合闸件优选小于第一联动件且将合闸件设置于第一联动件内部，所述合闸件由第一侧壁311、第一连接壁315和第二侧壁312依次连接形成U形结构，相对的所述第一侧壁311、第二侧壁312上设有用于穿接滑动杆102的通孔，第一连接壁315穿过第一联动件的连接槽30b使合闸件的第二侧壁312位于第一联动件内部，在第二侧壁312与第一联动件之间的滑动杆102上套设有弹性的缓冲件4，第一侧壁311或第二侧壁312设有用于操作断路器手柄5合闸的合闸操作部31a，所述合闸操作部31a伸出第一滑槽101并优选由第一侧壁311的中部边缘向第一滑槽101方向延伸形成，所述合闸操作部31a的端部向下弯折。
如图15所示，第二联动件由第四联动壁304、第六联动壁306和第五联动壁305依次连接形成U形结构，相对的所述第四联动壁304、第五联动壁305上设有供滑动杆102穿过的通孔，第六联动壁306上设有弧形的第二联动槽30c，所述分闸传动轴206a伸入第二联动槽30c内带动第二联动件运动。第二联动槽30c包括依次包括连通的第二平直段和第二圆弧段，第二平直段平行于滑动杆102，第二圆弧段接近半圆圆弧状，所述封闭端位于第二圆弧段端部，第二圆弧段的一侧呈圆弧侧壁，另一侧为直线侧壁，敞开端位于第二平直段端部，敞开端的敞口设置于第四联动壁304与第六联动壁306的连接处。当分闸传动轴206a从敞开端转入沿圆弧侧壁移动至封闭端带动第二联动件运动，随后沿直线侧壁转出与第二联动件分离，防止在合闸时产生误动作。
所述分闸件设置于第二联动件内，分闸件由第三侧壁313、第二连接壁316和第四侧壁314依次连接形成U形结构，相对的所述第三侧壁313、第四侧壁314上设有供滑动杆102穿过的通孔，所述第三侧壁313或第四侧壁314设有用于操作断路器的手柄5分闸的分闸操作部31b，优选的由第三侧壁313一体形成分闸操作部31b，所述分闸操作部31b整体呈敞口向上的U形体，所述U形体具有一个用于与第三侧壁313连接的长侧壁和一个用于与断路器的手柄5接触的短侧壁。分闸件位于第四联动壁304与第五联动壁305之间，位于第四侧壁314与第四联动壁304之间的滑动杆102上套接有弹性的缓冲件4，所述弹性的缓冲件4优选为弹簧。
特别的，作为一种实施例如图6、16所示，可以将第二联动槽30c设置于分闸件的第二连接壁315上，不设置联动件，由分闸传动轴206a通过第二联动槽30c带动分闸件在第一滑槽101内作直线运动，此时第二联动槽30c的敞开端的敞口设置于第三侧壁313与第二连接壁316的连接处，由此可以省略第二联动件以及设置在第二联动件与分闸件之间的弹性的缓冲件4，图6中的分闸件即为省略掉第二联动件和弹性的缓冲件4。
需要指出的是，由于合闸输出齿轮205和分闸输出齿轮206彼此啮合，两者的转动方向相反，因此第一联动槽30a，第二联动槽30c两者的敞开端的敞口方向错位相对,两者的封闭端相对错位，第一联动槽30a的敞开端到封闭端的方向与第二联动槽30c的敞开端到封闭端的方向相反，两者的转动方向相反。如 图8所示，第一联动槽30a的封闭端在第一联动件的左边，第二联动槽30c的封闭端在第二联动件的右边；第一联动槽30a的敞开端位于第一联动件的右上方，第二联动槽30c的敞开端位于第二联动件的左下方。
如图17-20所示的实施例，采用一个联动件和一个操作件，合闸操作部31a和分闸操作部31b为一体结构。所述驱动件包括联动件和操作件，联动件与传动机构配合，联动件安装在滑动杆102上，操作件安装在滑动杆102上且与联动件联动，联动件与操作件之间设有弹性的缓冲件4；所述联动件上设有联动槽3a，操作件包括连接在一起的合闸操作部31a和分闸操作部31b；传动机构的分合闸输出齿轮设有传动轴，所述传动轴与联动槽3a配合带动驱动件沿滑动杆102做直线运动，操作件的合闸操作部用于操作断路器的手柄5合闸，分闸操作部用于操作断路器的手柄5分闸。
本实施例中，传动机构只需设置一个分合闸输出齿轮，无需分别设置合闸输出齿轮205和分闸输出齿轮206，分合闸输出齿轮上设置一个分合闸传动轴，，分合闸输出齿轮可以采用圆齿轮，分合闸传动轴与联动件的联动槽3a连接通过操作合闸操作部31a使断路器的手柄5合闸，通过操作分闸操作部31b使断路器的手柄5分闸。
如图17、18所示的，所述联动件由两个横向联动壁31和一个竖向联动壁32连接形成一个敞口朝向第一滑槽101的U形结构，所述两个横向联动壁31设有供滑动杆102穿过的通孔，竖向联动壁32上设有联动槽3a，所述联动槽3a与传动机构配合使联动件带动驱动件沿滑动杆102运动来操作断路器的手柄5分闸或合闸。优选的，设置于竖向联动壁32上的联动槽3a为两端封闭的且呈条形的联动槽3a，所述联动槽3a的中心轴线与滑动杆102相垂直，分合闸传动轴伸入联动槽3a内带动联动件沿滑动杆作直线运动。
