 背景技术
隔离开关，即在分位置时，触头间有符合规定要求的绝缘距离和明显的断开标志；在合位置时，能承载正常回路条件下的电流及在规定时间内异常条件下的电流的开关设备。
隔离开关的操作机构一般设有储能机构，如弹簧，通过储能机构蓄能，瞬时释放，瞬时接通与断开触头结构，使合闸时的接通时间和分闸时的分断时间与操作手柄的操作速度无关，进而提高了各项电气性能与机械性能。目前现有常见的用于隔离开关的操作机构，其内一般只设置一个储能机构，如专利CN201610764579.8所公开的隔离开关的操作装置，其中只设置一个储能机构，即设置在联动盘与壳体之间的两个蓄力弹簧，这样的结构存在问题：分闸时， 输出轴转动角度为储能机构释放的能量所推动，储能机构释放的能量有限和转动角度有限，导致输出轴转动角度无法达到预期，也就是分闸时开度可能出现不够的问题。

所述输入轮与壳体之间设有第一储能机构；
所述输入轮与输出轮或第一输出轴之间设有第二储能机构；
所述第一输入轴由合闸位置旋转至分闸位置的旋转路径中，所述第一储能机构具有储能状态和释能状态，当所述第一储能机构为储能状态时，所述联动件位于联动槽内滑移，所述限位机构保持第一位置，所述第二储能机构为储能状态；当所述第一储能机构为释能状态时，所述联动件抵接联动面，所述限位机构为第二位置，所述第二储能机构为释能状态。

 本发明的最佳实施方式
如图1-图3所示，一种隔离开关的双储能操作机构，包括壳体1，所述壳体1内转动设置有第一输入轴2及第一输出轴3，所述第一输出轴3至少一端延伸至壳体1外作为与隔离开关联动的输出端，所述第一输入轴2至少一端延伸至壳体1外作为操作端，所述壳体1内设有与第一输出轴3同轴设置的输入轮6、与第一输出轴3同轴设置的且与其周向联动的输出轮4以及至少部分材质为弹性材质且被周向锁定的限位机构5，所述输出轮4上设有第一限位部401和联动槽402，所述限位机构5上设有第二限位部501和具有推动斜面506的第一推动部502，所述输入轮6上设有部分位于联动槽402内的联动件601和与第一推动部502配合的第二推动部602，所述联动槽402周向两端设置有与联动件601抵配的联动面403，在所述第一输入轴2转动的至少部分路径中所述第一输入轴2带动输入轮6转动，所述第二推动部602与限位机构5中的弹性材质部分相互作用且在所述输入轮6的旋转路径中第二推动部602与推动斜面506始终保持抵触使所述限位机构5具有第二限位部501与第一限位部401互相抵扣使输出轮4被周向锁定的第一位置，以及第二限位部501与第一限位部401分开使输出轮4解锁为可转动状态的第二位置；
所述输入轮6与壳体1之间设有第一储能机构7；
所述输入轮6与输出轮4或第一输出轴3之间设有第二储能机构8；
所述第一输入轴2由合闸位置旋转至分闸位置的旋转路径中，所述第一储能机构7具有储能状态和释能状态，当所述第一储能机构7为储能状态时，所述联动件601位于联动槽402内滑移，所述限位机构5保持第一位置，所述第二储能机构8为储能状态；当所述第一储能机构7为释能状态时，所述联动件601抵接联动面403，所述限位机构5为第二位置，所述第二储能机构8为释能状态。
在输入轮与壳体之间和输入轮与输出轮或第一输出轴之间分别设置第一储能机构和第二储能机构，并对输出轮设置限位机构，限位机构在第一储能机构储能时对输出轮形成锁定作用，进而使第二储能机构同时进行储能，在第一储能机构开始释能时解除限位机构的锁定作用，使输出轮和第一输出轴可转动，第一储能机构和第二储能机构同时释放能量，形成双重储能助推作用，第一输出轴转动的角度更大，提高隔离开关各项电气性能与机械性能。
如图5-图7所示，所述限位机构5设置在输出轮4与壳体1内壁之间。所述限位机构5包括固定部503，所述第二限位部501、第一推动部502、固定部503依次连接，所述固定部503与壳体1内壁保持连接，所述第一限位部401为凸起的台阶部，所述第二限位部501抵住第一限位部401，所述第一推动部502在壳体1内壁与输出轮4之间倾斜设置，所述第一推动部502为弹性材质制成。
所述限位机构5包括两个关于第一输出轴3轴心对称设置的固定部503，所述固定部503两侧向外向输出轮4方向倾斜延伸形成两个弧形的第一推动部502，所述第一推动部502靠近输出轮4的外端部凸起形成第二限位部501，所述输入轮6上设有两个关于轴心对称的第二推动部602，所述输出轮4对应设有两个关于轴心对称的第一限位部401。
如图6所示，限位机构5为呈环形的由金属材质一体成型的簧片，从固定部503两侧开始拱起，在外端部凸起形成第二限位部501。
如图7所示，所述第一限位部401设有导向斜面405，所述导向斜面405对所述第二限位部501形成沿输出轮4从分闸转向合闸方向的导向作用。所述壳体1内壁设有与所述固定部503适配的限位凹槽101，所述固定部503卡设在限位凹槽101内。导向斜面405便于合闸时限位机构5的复位。
所述第二推动部602为联动件601的端部，所述联动件601穿过联动槽402，且在所述输入轮6的旋转路径中其端部与推动斜面506保持抵触。
所述第二储能机构8为弹簧，所述弹簧的两端分别抵接联动件601和输出轮4。
所述输出轮4上设有环形槽406、与所述环形槽406连通的第一限位槽407，所述第二储能机构8设置在环形槽406内且一端固定在第一限位槽407内，另一端固定在第二限位滑槽408内与联动件601联动配合。
所述第一储能机构7为弹簧，所述弹簧的两端分别连接输入轮6和壳体1。
其中，输出轮4也可以在边缘和其它部位被锁住和脱扣。
其中，固定部503也可以采取通过胶黏剂连接、通过螺栓连接的方式固定，不过在本实施例中，限位机构夹设在壳体内壁与输出轮4之间，限位机构本身又具备一定弹力，所以输出轮4以及第二推动部602对限位机构的推力使固定部503可以很好地保持在限位凹槽101内，这样更好组装。
如图11-13所示，所述第一输入轴2上同轴且周向联动设置有第一齿轮9，所述输入轮6上同轴且周向联动设置有第二齿轮10，所述第一齿轮9与第二齿轮10呈垂直排布且相对设置，所述第一齿轮9与第二齿轮10之间设有传动机构11，所述传动机构11具有与第一齿轮9啮合的第一齿1101、与第二齿轮10啮合的第二齿1102，在第一齿轮9转动的至少部分路径中通过该传动机构11使第二齿轮10转动。这样的结构，传动更加稳定、准确。
所述传动机构11包括第一齿条1103和第二齿条1104，所述第二齿条1104上设有与第一齿条1103适配的第一限位滑槽1105，所述第一齿条1103位于第一限位滑槽1105内沿直线与所述第二齿条1104滑移配合，所述第一齿1101设置在第一齿条1103上，所述第二齿1102设置在第二齿条1104上，所述第一限位滑槽1105两端设有与所述第一齿条1103抵配的挡块1106。
所述壳体1内壁设有与所述传动机构11适配的第二限位滑槽102，所述传动机构11位于第二限位滑槽102内沿直线与壳体1之间滑移配合。
当旋转操作手柄13时，先带动第一齿条1103在第一限位滑槽1105内滑移，当第一齿条1103抵触至一端的挡块1106时，第一齿条1103带动第二齿条1104在第二限位滑槽102内滑移，进而使第二齿轮10、输入轮6转动，且第二限位滑槽102内在传动机构11底部位置嵌设有金属弹性片12，所述金属片12拱起对传动机构11形成向第一齿轮9方向的推力，通过以上的联动设计，可以使第一齿轮9和第一齿1101更好的啮合更可靠，同时可以使传动机构和限位滑槽 102之间的摩擦系数降低大大的提升机械寿命。
输入轮6上设有一个插孔603，可以根据不同的工况在插孔603内通过插接连接有与输入轮6周向联动的第二输入轴14，使操作的位置进行调整，第二输入轴14也可以更换与第一输出轴3联动的第二输出轴15，形成双输出端的操作结构。
如图16所示，以旋转角度为90°的操作机构为例，输入轴由合闸旋转到分闸然后再旋转到合闸，第二推动部、输出轮、限位机构三者的位置关系变化，如图16（a）所示，合闸状态下，限位机构5的第一推动部502卡在输出轮4的第一限位部401（台阶）一侧，使输出轮无法转动；如图16（b）所示，从合闸转到分闸逆时针旋转45°，第一储能机构7完成储能，第二储能机构8完成储能，第一推动部502被第二推动部602推动离开第一限位部401（台阶）一侧，同时联动件601抵触联动面403，第一储能机构7释放能量，推动输出轮4逆时针转动，且第二储能机构8释放能量，助推输出轮4逆时针转动；如图16（c）第三视图所示，完成分闸时，限位机构5抵接导向斜面405。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
