如图4所示，所述分合指示器24通过齿轮组与第一输出轴7传动连接，所述齿轮组包括圆柱齿轮组29和圆锥齿轮组，通过两个齿轮组，第一输出轴7的转动角度就能通过分合指示器24的指针显示，使现场操作人员能清楚的知道高压开关的分合闸情况。
所述辅助开关由三个并列开关组成，中间为一号开关26，两边分别为二号开关25和三号开关27，其中，位于中间位置的一号开关26通过辅助开关传动齿轮组28与蜗轮蜗杆减速机21的第二输出轴相连，一号开关26和二号开关25、三号开关27之间通过平行四连杆联动。在其他实施方式中，所述辅助开关也可以通过两边的二号开关25或三号开关27与蜗轮蜗杆减速机21的第二输出轴相连，因为三个并列开关是联动的，任意一个连接所述第二输出轴均可。
本发明实施例的高压开关中，控制器4构成整个高压开关设备的控制装置的核心控制元件，在高压开关正常运行时，控制器4下达分合闸指令，这些指令通过光纤及动力电缆6输送至操作装置2内的伺服电机23，伺服电机23根据这些指令驱动传动机构动作，将分合闸动作传递给开关本体1，进而使开关本体1完成分合闸动作。在整个开关动作的过程中，伺服电机23在动作的同时还不停地对控制器4反馈伺服电机23的运动状态信号，这些运动状态信号主要是位置信号，控制器4根据伺服电机23反馈回来的位置信号进行处理并确定伺服电机23是否运动到位；
所述控制柜3外壁设有将控制器4处理后的反馈信号进行显示的显示器5，操作人员可以通过显示器5上的信息对高压开关的工作情况进行监控，一方面可以在高压开关的工作发生异常时及时进行调整，避免因发现不及时造成异常现象恶化的情况发生；另一方面，操作人员还可以根据显示器5上的信息变化情况对高压开关的工作情况进行预测，根据预测结构对装置进行提前调整，在异常现象发生之前将异常源处理掉，从而实现高压开关设备的智能化控制，提高高压开关设备的运行可靠性；
作为一种实现方式，所述控制柜3还可以设置声光报警部件，在高压开关的工作发生异常时，进行声光报警。
此外，控制器4与伺服电机23之间通过光纤通讯，具有极强的防电磁干扰性能，能够有效避免其他干扰带来的开关误动。控制柜3设置有屏蔽外壳，具有抗电磁干扰性能，可以防止其他信号对控制柜3内的控制装置产生干扰，造成控制系统紊乱。
传动机构的核心是蜗轮蜗杆减速机21，将原操动机构中分散在机架各个部位的传动机构由一个核心传动机构蜗轮蜗杆减速机21代替，不仅实现了传动机构的集中布置，减小了装置的体积。而且，蜗轮蜗杆减速机21本身自带机壳，可以对机壳内的部分进行单独保护，在实际使用过程中能有效的降低传动机构的故障率。另一方面，传动机构的这种结构设计也有效的降低了操作装置2的零件数量，降低了故障源数量，从而提高了操作装置2的运行可靠性，也降低了操作装置2的装配难度。
分合指示器24和辅助开关通过齿轮组设置在蜗轮蜗杆减速机21的与分输出轴平行的侧面处，将蜗轮蜗杆减速机21的四周包围，不仅充分利用蜗轮蜗杆减速机21的四周空间，而且齿轮传动本身结构紧凑，这样使整个机构看起来紧凑集中，进一步减小了操作装置2的整体体积。
本发明的高压开关，不仅通过控制装置的设置实现高压开关运动过程 的闭环控制，实现高压开关运动过程的智能化控制，提高了高压开关的运行可靠性。而且操作装置2的集成布置式的设计不仅减小了操作装置2的装置体积，而且降低了操作装置2的故障率，进一步提高了高压开关的运行可靠性。
作为本发明的另一种实施方式，所述分合指示器24和辅助开关也可以设置在蜗轮蜗杆减速机21的两个相对的侧面处，这样，能适用更多的应用场合。
作为本发明的另一种实施方式，所述传动机构也可以不设置行星减速机22，这样，虽然传动机构的速度调控范围减小，但机构更精简，运行更可靠。
作为本发明的另一种实施方式，分合指示器24和辅助开关也可以通过齿轮齿条或齿轮链条等方式与蜗轮蜗杆减速机21的输出轴传动连接，这样，虽然设备占用空间变大，但结构更简单，更便于维护。
作为本发明的另一种实施方式，所述伺服电机23也可以是其它控制电机，如步进电机；还可以是由液压缸加直线运动变旋转运动机构组合的可以输出旋转运动的其它驱动机构代替；这样，可以适用更多应用场合。
作为本发明的另一种实施方式，所述控制器4和显示器5也可以不设置在控制柜3中。例如，当本装置在气体绝缘金属封闭开关设备(GIS，GAS insulated SWITCHGEAR)系统中使用时，如果GIS间隔汇控柜空间允许，可将控制器4、显示器5及其他附件安装于汇控柜内而不设置控制柜3，这样，可以进一步节省设备占用的空间。
