进一步的，本实施例中还给出了传动组件的具体结构，如图2所示，所述传动组件包括主动齿轮11、第一传动齿轮12、第二传动齿轮13、传动轴14和从动齿轮15；
具体的，所述主动齿轮11固定套装在减速机5的输出轴上，所述从动齿轮15固定套装在机构转轴4上；所述第一传动齿轮12、第二传动齿轮13固定套装在传动轴14上，所述传动轴14能够转动的安装在壳体3内壁上，且位于减速机5的输出轴与机构转轴4之间；所述第一传动齿轮12与主动齿轮11啮合，所述第二传动齿轮13与从动齿轮15啮合。
减速机5转动时，减速机5的输出轴带动主动齿轮11转动；由于主动齿轮11与第一传动齿轮12啮合，因此主动齿轮11转动能够带动第一传动齿轮12及传动轴14转动，同时传动轴14转动能够带动第二传动齿轮13转动，由于第二传动齿轮13与从动齿轮15啮合，进而第二传动齿轮13转动能够带动从动齿轮15及机构转轴4转动。
作为优选的方式，如图2—4所示，本实施例中所述传动组件还包括第一法兰盘16、第二法兰盘17和转轴套筒18；具体的，所述第一法兰盘16固定套装在机构转轴4上；所述第二法兰盘17和转轴套筒18均活动套装在机构转轴4上，第二法兰盘17的一侧与转轴套筒18固定连接，其另一侧设有法兰拨杆19；所述第一法兰盘16上设有配合法兰拨杆19的弧形通孔20；所述从动齿轮15通过键固定套装在转轴套筒18上；所述第二法兰盘17上的法兰拨杆19配合第一法兰盘16上的弧形通孔20能够为减速机5的动作提供空行程。同时通过该空行程可也避免手动操作与电动操作的相互影响。
作为优选的方式，本实施例中所述机构转轴4和隔离开关主轴6上均设有连接孔25，机构转轴4和隔离开关主轴6之间通过连接套及穿过连接套和连接孔25的销轴连接。
作为优选的方式，本实施例中所述隔离开关主轴6远离机构转轴4的一端安装有手动操作分合闸操作板26，通过手动操作分合闸操作板26能够对隔离开关主轴6进行手动合分闸操作。
在本实用新型的另一实施例中，为了配合隔离开关的辅助开关24，如图3所示，所述电控机构箱1还包括设于壳体3内的辅助开关切联动组件；
具体的，所述辅助开关切换机构包括拨杆21、拨叉22和转换板23；所述拨杆21和转换板23均设置于拨叉22上，所述转换板23一侧与机构转轴4的另一端固定连接，转换板23另一侧的偏心位置与隔离开关的辅助开关24的主轴连接；当机构转轴4转动时，所述转换板23通过拨杆21和拨叉22能够将隔离开关的辅助开关24的主轴的转动角度增大至90度，使隔离开关的辅助开关24能够真实反映开关分合闸状态。
该用于隔离开关分合闸的智能电动操控装置的具体操作过程如下：
由于隔离开关的开合角度较小，机构转轴4直接连接辅助开关无法保证其可靠转换，所以设计了拨叉22、拨杆21、转换板23的结构将二者连接，并将转换板23与机构转轴4的连接采用偏心的形式，在隔离开关分合闸时增加辅助开关的转换角度，使辅助开关跟随隔离开关分合闸实现可靠转换。当开关分合闸完成，辅助开关跟随完成转换，提供信号指示，辅助开关接点对数可根据实际需要提供。
所述电控机构箱1与控制箱2采用分离的设置方式，控制箱2设置于人员易操作的地方，通过线路与电控机构箱1连接，为电控机构箱1的减速机5提供电源，并接收电控机构箱1内微动开关组件的分合闸到位信号接点。由于微动开关8和9采用常开触点开关，当按下控制箱2的分合闸按钮，减速机5开始动作，机构转轴4上的凸轮7压到微动开关8和9常开触点后，微动开关8和9与控制箱2连接的回路闭合，提供了开关分合闸到位信号，控制箱2的分闸或者合闸指示灯亮起，代表开关分闸或合闸到位，减速机5停止工作。为实现电机保护，控制箱2的电路板可以写入电机堵转保护程序，当电控机构箱1或隔离开关工作过程中出现卡死等故障造成减速机5堵转时，控制箱2可控制减速机5停止工作，并使电机反转一定角度，解除齿轮卡死状态，防止减速机5损坏。控制箱2还设有异常情况下使用的停止按钮，当工作过程中发生异常情况时，可按下停止按钮，使电控机构箱1的减速机5立即停止工作。
具体的工作过程如下：当隔离开关处于合闸状态，按下分闸按钮，减速机5开始工作，机构转轴4带动隔离开关主轴6开始转动，隔离开关主轴6在机构转轴4的带动下开始分闸，机构传动轴14上的凸轮7随着机构转轴4转动，当开关分闸到位，机构转轴4上的凸轮7压动分闸的微动开关8，分闸的微动开关8常开触点闭合，为控制箱2提供分闸到位信号，减速机5停止工作，隔离开关分闸完成；同理，当隔离开关处于分闸状态时，按下合闸按钮，机构转轴4上的凸轮7随着机构转轴4反转，凸轮7压动合闸的微动开关9，合闸的微动开 关9常开触点闭合，为控制箱2提供合闸到位信号，即可完成隔离开关的合闸。
隔离开关主轴6另一侧上装有手动操作分合闸操作板26，可以通过绝缘拉杆手动操作隔离开关分合闸时，由于传动组件提供的空行程，使得隔离开关的电动操作与手动操作不会相互产生影响，所以将该用于隔离开关分合闸的智能电动操控装置安装在隔离开关上，除了能实现隔离开关的电动操作外，也可手动操作隔离开关分合闸，为隔离开关的分合闸操作提供了双重保证。
以上，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
