Description

断路器的操作机构 技术领域
本发明涉及低压电器领域，更具体地说，涉及开关电器的操作机构。
背景技术
断路器是低压配电网中主要的起到保护作用的开关电器，断路器为线路提供过载和短路保护。塑料外壳式断路器是其中的一种，而大容量塑壳断路器是指额定电流达到或超过800A的断路器，该断路器通常为三极和四极结构，即该断路器具有三组或者四组触头，对应三相或者四相电路。为了满足电力系统中一定的选择性保护要求，断路器必须有一定的短时耐受能力。因此，大容量塑壳断路器的触头组件，尤其是多极的传动组件必须有较高的强度与刚度，满足多极的触头压力、超程等参数的均一性。另一方面，考虑到成本和应用市场，大容量塑壳断路器的操作机构绝大部分为手动操作型式，在满足人力操作力的要求下，操作机构的输出功率往往有限，因此断路器手动操作机构往往要求输出功率尽可能高，又能够保证多极触头参数的均一性。
现有的大容量塑壳断路器的触头系统和传动机构通常为分开的结构，由于传动机构的强度和刚度问题，其触头参数很难保证均一，很难达到选择性保护的要求，另一方面现有的操作机构本身的性能，比如操作力和脱扣力、动作速度、机械寿命等较差，难以满足高性能断路器的需要。
在一些产品中，多极触头被铆接在绝缘件上，绝缘件内包有金属轴以提高强度和刚度。断路器的操作机构通过驱动某一极触头系统来绝缘件驱动多极触头。然而，随着温度、湿度及机械应力的变化，绝缘件的绝缘层往往产生松动，使得多极触头钣金支架与绝缘件的铆接失效，多极触头参数较难保证均一。
在另一些产品中，多极触头安装在整体绝缘转轴上，绝缘转轴通过相 间的圆柱面与断路器壳体内腔进行配合，形成转动副。该种传动方式结构紧凑，安装方便，但对绝缘件的工艺及材料要求较高，往往随着操作次数的增加，多极触头参数很难保证均一，另外转动副的摩擦较大，操作机构的使用效率得到较大程度的限制。
还有一部分大容量塑壳断路器的操作机构考虑了触头参数均一性的问题。比如公开号为CN99805429.1的专利申请揭示了一种高电动力强度的低压多极断路器，包括一个由绝缘材料制成的盒体，该盒分成用于存放打开和闭合操作断路器的操作机构的前仓、和由中间壁从前仓分开的后仓。后仓被分隔部分再分成单独仓，每个单独仓存放断路器的一个电极。操作机构连接到所有电极的公共电极轴。电极轴位于后仓中、并由穿过分隔部分的轴承支撑。该专利申请所揭示的方案中的电极轴成型工艺效率较低，导致方案实现成本高，较难获得具有竞争力的成本优势。而且多极动触头系统与电极轴及与操作机构本身的安装较复杂，对厂商的制造和装配要求较高。
公开号为CN200680016460.7的专利申请揭示了一种用于低电压系统的单极或多极开关。开关包括一个外壳，外壳对于每个电极包含至少一个固定触头和至少一个可移动触头，两者可彼此连接/分开。可移动触头被容纳在一个适当的底座中，底座布置在可移动部件上。开关还包括一个能量积累控制机构，控制机构可操作地连接到可移动部件上，以允许其运动。根据本发明的开关优选地配置有轴向支撑装置，轴向支撑装置可操作地连接到可移动部件，用于承受沿可移动部件本身转轴所产生的重力冲击，重力冲击是在轴相对于大致水平面倾斜时产生的。该专利申请的方案中将动触头组件安装在整体的绝缘件上，并将该绝缘件的转动中心通过销轴与钣金件固定到操作机构侧板上，形成悬浮结构。该绝缘件的成型工艺极复杂，具有多面抽芯结构，生产效率较低，对工艺要求极高，导致实现成本过高。

在一个实施例中，杠杆组件和主轴组件上具有隔离装置，隔离装置在动触头熔焊时限制操作手柄，使操作手柄不能进行分闸。

在一个实施例中，锁扣组件包括钣金件、轴承、锁扣组件弹簧和转轴。钣金件安装在转轴上，锁扣组件弹簧套在转轴上，锁扣组件弹簧对钣金件施加弹簧力，轴承安装在钣金件上，轴承与跳扣第二端的第二斜面接触，锁扣组件限制跳扣组件。
在一个实施例中，半轴组件包括半轴，半轴的两端分别安装在左侧板组件和右侧板组件上，钣金件与半轴组件接触。跳扣组件、锁扣组件和半轴组件共同构成二级锁扣。
在一个实施例中，第二斜面包括圆弧面。
在一个实施例中，主轴组件包括主轴，主轴上具有多个悬臂，主轴上还具有主轴限位件，主轴限位件固定轴共同限制分闸过程中操作机构的行程，固定轴固定在左侧板组件和右侧板组件上。

在一个实施例中，隔离装置包括位于主轴限位件上的限位块和位于钣金折弯件上的浅钩形的延伸部。
本发明的断路器的操作机构适用于具有一定选择性保护的大容量塑壳断路器，是手动的操作机构。该操作机构基于外置金属主轴传递触头参数，保证触头参数的均一性。实现成本较低，要求的工艺难度也较低，具有较高的装配便捷性，能够有效提升操作机构的性能，满足高性能断路器的需要。

结合图1、图2a、图2b、图3a、图3b、图4a、图4b、图5、图6a、图6b、图7a和图7b，跳扣组件100、左侧板组件101、锁扣组件102、半轴组件103、右侧板组件104、杠杆组件105和主轴组件106以如下的方式组装成操作机构107。跳扣组件100的转轴208的两端分别安装在左侧板组件101的跳扣安装孔280(位于左侧板209上)和右侧板组件104的跳扣安装孔281(位于右侧板309上)。杠杆组件105的钣金折弯件228的两侧侧壁底部的半圆形的缺口241分别架设在左侧板组件101和右侧板组件104的转轴213上。如前面所述的，转轴213是短轴，两个转轴213分别安装在左侧板209和右侧板309上，转轴213朝向内侧的端部具有端 盖，端盖的直径大于转轴，端盖对钣金折弯件228的侧壁进行横向的限位。杠杆组件105中的杠杆组件弹簧231底部的连接孔234与上连杆201下端的连接孔236对齐，连接轴235穿过连接孔234和连接孔236，将杠杆组件弹簧231与上连杆201连接。主轴组件106的主轴237穿过两个安装配件的第一部分242上的孔，使得主轴237被连接到两个安装配件上。主轴237被放置到左侧板组件101的半圆形缺口299(位于左侧板209上)和右侧板组件104的半圆形缺口399(位于右侧板309上)中，两个安装配件的第二部分243上的螺孔分别对准左侧板组件101上的安装孔290(位于左侧板209上)和右侧板组件104上的安装孔291(位于右侧板309上)。螺钉穿过两个安装配件的第二部分243上的螺孔以及安装孔290、291，将安装配件固定在左侧板组件和右侧板组件上，也完成主轴组件106与左侧板组件101和右侧板组件104的装配。主轴组件106的其中一个悬臂238与跳扣组件100的下连杆202连接，悬臂238上的连接孔与下连杆202下端的连接孔282由销轴246连接(销轴246在图11中揭示)，形成连杆结构，主轴组件106与跳扣组件100实现连接。对于具有多极结构的多相电路来说，主轴组件106上具有多个悬臂238，每个悬臂238对应一极，操作机构107安装在其中某一极的结构上。对应该极的悬臂238与操作机构的跳扣组件中的下连杆连接。对于左侧板组件101和右侧板组件104来说，除了借助于锁扣组件102的转轴217进行固定之外，在相对于锁扣组件102的另一端还具有另一个固定轴247。固定轴247同样穿过位于左侧板组件和右侧板组件上的孔并由螺钉固定，固定轴247和转轴217一起将左侧板组件101和右侧板组件104固定在一起。
参考图8～图10，揭示了操作机构107与断路器108的装配结构图。其中图8和图9是去除断路器的顶盖后的结构图，图10是盖上断路器的顶盖后的结构图。参考图8和图9所示，断路器108包括基座109和中盖159。在图示的实施例中，断路器108是一个多极断路器，具有对应多相电路的多极动触头110。操作机构107安装在其中一极的动触头上。螺钉 249与操作机构的左侧板组件101和右侧板组件104上的螺母211配合，将左侧板组件101和右侧板组件104固定在中盖159上，从而将操作机构107安装到其中一极的动触头上。多极动触头110通过销轴250分别连接到主轴组件106的对应的悬臂238上，每一极的动触头110连接到与之对应的悬臂238。销轴250固定在悬臂238上的连接孔中。参考图7a，每一个悬臂238上具有两个连接孔，其中上方的连接孔用于与跳扣组件连接，下方的连接孔用于与动触头连接。操作手柄230安装在杠杆组件105上，更加具体地说，操作手柄230安装在安装轴229上。图10是断路器108盖上顶盖后的结构图，在盖上顶盖后，图10所示的断路器108可见到基座109、中盖159、顶盖和操作手柄230。
该断路器108实现各个功能的动作过程如下：
图11a和图11b揭示了根据本发明的一实施例的操作机构带动动触头进行合闸的过程。图11a主要揭示了操作机构的合闸过程，图11b揭示了操作机构带动动触头合闸的过程。在进行合闸时，跳扣组件100中的跳扣204的尾端，钩形的外侧所形成第二斜面253被轴承221顶住并被轴承221所限制。锁扣组件102的钣金件219被半轴组件103的半轴223所限制。杠杆组件105在人力作用下绕转轴213逆时针运动，比如，人力推动操作手柄230来带动杠杆组件转动。在图11a和图11b所示的实施例中，图示的合闸方向如箭头所指，是使得杠杆组件逆时针转动。在推动杠杆组件105逆时针转动后，杠杆组件弹簧231驱动上连杆201以销轴203为转轴转动，上连杆201绕销轴203顺时针转动。上连杆201带动下连杆202运动。下连杆202通过销轴246带动主轴组件106的悬臂238(该悬臂238于跳扣组件100连接)，悬臂238进一步带动主轴237围绕主轴的轴心106A转动，主轴237围绕轴心106A顺时针转动。主轴237的转动带动其他的悬臂238联动，各个悬臂238通过销轴250带动各个动触头110完成合闸。各个动触头110围绕各自的转动中心255逆时针转动。回到图2a，上连杆201顺时针转动的极限位置被限位销钉205所限制，当上连杆201转动 至与限位销钉205接触时，上连杆201不再转动。于是，合闸完成后，上连杆201由限位销钉205进行限位。
图12a和图12b揭示了根据本发明的一实施例的操作机构带动动触头进行分闸的过程。图12a主要揭示了操作机构的分闸过程，图12b揭示了操作机构带动动触头分闸的过程。在进行分闸时，杠杆组件105在人力作用下绕转轴213顺时针运动，比如，人力推动操作手柄230来带动杠杆组件转动。在图12a和图12b所示的实施例中，图示的分闸方向如箭头所指，是使得杠杆组件顺时针转动。在推动杠杆组件105顺时针转动后，杠杆组件弹簧231驱动上连杆201以销轴203为转轴转动，上连杆201绕销轴203逆时针转动。上连杆201带动下连杆202运动。下连杆202通过销轴246带动主轴组件106的悬臂238(该悬臂238与跳扣组件100连接)，悬臂238进一步带动主轴237围绕主轴的轴心106A转动，主轴237围绕轴心106A逆时针转动。主轴237的转动带动其他的悬臂238联动，各个悬臂238通过销轴250带动各个动触头110完成分闸。各个动触头110围绕各自的转动中心255顺时针转动。结合参考图7a，主轴237逆时针转动的极限位置由主轴限位件239、240和固定轴247所决定。参考图12a和图12b，当主轴限位件239、240与固定轴247接触时，主轴部件不再转动。
图13a和图13b揭示了根据本发明的一实施例的操作机构处于自由脱扣位置的结构图。图13a主要揭示了操作机构在自由脱扣位置的状态，图13b揭示了操作机构和动触头在自由脱扣位置的状态。在断路器108处于合闸状态时，操作机构107的半轴组件103接收到脱扣信号，脱扣信号可以由安装在半轴223上的第一故障接收件224和第二故障接收件225接收(参考图1)。接收脱扣信号的形式可以是外力推动第一故障接收件224和/或第二故障接收件225，带动半轴223转动。半轴223转动后，半轴组件103解锁锁扣组件102，锁扣组件102在锁扣组件弹簧222的作用下逆时针旋转(参考图3b)，轴承211不再限制跳扣组件100尾部的第二斜 面253，锁扣组件102解锁跳扣组件100。由于跳扣组件100中的上连杆201被限位销轴205限制定位(参考图2a)，在杠杆组件105的杠杆组件弹簧231的作用下，跳扣组件100，或者说是跳扣204以转轴208的中心208A为轴心转动，跳扣204的转动方向为逆时针。跳扣204的转动通过上连杆201、下连杆202和悬臂238(该悬臂238与跳扣组件100连接)传递到主轴237，实现跳扣组件101带动主轴组件106的转动。主轴237围绕轴心106A逆时针转动。主轴237的转动带动其他的悬臂238联动，各个悬臂238通过销轴250带动各个动触头110围绕各自的转动中心顺时针转动，动触头打开完成脱扣。自由脱扣动作完成后，在杠杆组件弹簧231作用下，杠杆组件105，或者说操作手柄230指示到自由脱扣位置，即操作手柄230处于竖直向上的位置，与水平面呈90度角。主轴限位件239、240与固定轴247接触，使得主轴237的转动被限位。跳扣204的第二端，钩形的内侧所形成的第一斜面256与杠杆组件105上的限位轴257接触，跳扣204被杠杆组件105所限位。
继续参考图13a和图13b，当断路器108处于自由脱扣位置时，断路器还可以进行再扣动作，或者说是复位动作。人力操作杠杆组件105，更具体地说是操作操作手柄230围绕转轴213顺时针转动。杠杆组件105的限位轴257压迫跳扣204的第一斜面256，带动跳扣204(或者说是跳扣组件100)至图12a所示的位置(分闸位置)。跳扣204的第二斜面253重新与轴承221接触并被轴承221所限制，锁扣组件102也重新由半轴组件103所限制。断路器再次处于分闸位置。
图14a和图14b揭示了根据本发明的一实施例的操作机构进行熔焊隔离指示的结构图。图14a主要揭示了操作机构在进行熔焊隔离指示的结构图，图14b揭示了操作机构和动触头在进行熔焊隔离指示的结构图。当多级动触头中的动触头110出现熔焊时，动触头110由于熔焊而与静触头188固定，无法再绕转动中心255转动。由于主轴组件106与动触头110联动，因此在动触头熔焊时，主轴组件106也不能绕转动中心106A转动，或者 说，主轴组件106被锁定在合闸位置。此时，如果人力操作杠杆组件105进行分闸，由于主轴组件106被锁死，容易造成机构损坏。为了避免这种情况，本发明的操作机构对熔焊状态下的操作机构设置了隔离保护功能。隔离保护功能由主轴限位件239和240的端部的限位块259和钣金折弯件228上“靴子”造型的浅钩形的延伸部258共同构成。参考图14a和图14b，当出现熔焊时，如果人力操作操作手柄230顺时针转动，准备进行分闸，那么当杠杆组件105顺指针转过一定的角度后，限位块259和“靴子”造型的浅钩形的延伸部258接触，使得杠杆组件105不能继续转动，无法抵达分闸位置。在人力消失后，在杠杆组件弹簧231的作用下，存在力矩，该力矩的力臂为L1，杠杆组件弹簧231通过力臂L1产生力矩使得杠杆组件105绕转轴213逆时针转动，重新回到合闸位置。图14a中箭头所指的方向为杠杆组件105在力矩的作用下自动复位的方向，为逆时针转动。
本发明的操作机构在合闸状态下提供二级锁扣功能。图15a和图15b揭示了根据本发明的一实施例的操作机构的二级锁扣示意图。如图所示，当跳扣204的第二斜面253被轴承221顶住而锁定时，存在力臂L5，锁扣组件弹簧222利用该力臂L5产生力矩驱使钣金件219绕转轴217逆时针转动，钣金件219的端部219A压紧半轴223。套在转轴217上的锁扣组件弹簧222利用力臂L5产生力矩。当进行再扣(复位)时，为保证轴承能够可靠地进入到第二斜面253并与之锁定，必须使得跳扣204存在过行程，在再扣的过程中，轴承221会压紧跳扣204上的面204A以及第二斜面253，并且与面204A和第二斜面253相切。前面提到，第二斜面253是一个圆弧面或者至少包括一部分的圆弧面，因此，圆弧形的面253能够保证力臂L5保持基本不变，以防止自锁现象的发生。
本发明的断路器的操作机构适用于具有一定选择性保护的大容量塑壳断路器，是手动的操作机构。该操作机构基于外置金属主轴传递触头参数，保证触头参数的均一性。实现成本较低，要求的工艺难度也较低，具有较高的装配便捷性，能够有效提升操作机构的性能，满足高性能断路器的需 要。
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。
