具体实施方式
以下结合附图1至7给出本实用新型的实施例，进一步说明本实用新型的断路器锁定装置具体实施方式。本实用新型的断路器锁定装置不限于以下实施例的描述。
如图1所示本实用新型的结构示意图，本实用新型的断路器锁定装置，包括执行杠杆1和压板2，所述的执行杠杆1孔轴旋转安装在断路器的基座3内，并且执行杠杆1的一端与基座3之间设有弹性件111，执行杠杆1的另一端设有可与压板2一侧的锁定部210锁定连接的锁定端120。所述的压板2安装在 基座3内且可相对于基座3旋转摆动，如图3所示压板2一侧的锁定部210包括与锁定端120分别对应设置的解锁面211和锁定面212，并且解锁面211与锁定面212相邻设置且中间设有滑动台阶213，压板2另一侧设有可与断路器操作机构接触连接的接触部220，压板2的上方还对应设有可驱动压板2摆动的磁通5，断路器故障时磁通5可推动压板2摆动使置于解锁面211内的锁定端120在弹性件111释能的作用力下沿滑动台阶213滑至锁定面212内将压板2锁定，同时随压板2摆动的接触部220可限制操作机构的分闸半轴恢复到最高位置即可合闸位置。本实用新型采用执行杠杆锁定压板可实现在断路器故障后操作机构的分闸半轴无法恢复至最高点完成合闸，以便用户查找故障及排除故障后能安全的操作断路器的合闸，确保了操作人员的安全及供电设备的安全运行。
特别地，所述的基座3内还设有可夹持安装压板2的支架4，压板2旋转安装在支架4内并与磁通5对应设置，所述磁通5在断路器故障时可收到控制器脱扣指令即推动压板2相对于支架4旋转摆动从而使锁定端120与锁定面212锁定连接。支架不仅便于锁定装置的组装，同时在压板摆动旋转时提供稳定支撑提高了锁定过程的稳定可靠性。
如图2所示本实用新型执行杠杆1的结构示意图，所述执行杠杆1的两端分别为与弹性件111对应设置的复位驱动端110和与压板2对应设置的锁定端120，所述的锁定端120包括呈V字型结构相互连接的第一作用面121和第二作用面122，所述第二作用面122与执行杠杆1端部相连接且平行于执行杠杆1设置，并且第一作用面121和第二作用面122连接处形成的作用端123可与锁定面212接触连接，第一作用面121可与滑动台阶213的对应侧接触连接，从而在锁定时锁定面212、第一作用面121与滑动台阶213的一侧可形成三角形结构。V型结构的锁定端实现了在执行杠杆锁定压板时，锁定端、锁定面及滑动台阶形成稳定的三角形结构，使锁定后的压板不易发生晃动，提高了锁定装置的稳定性。特别地，滑动台阶213的顶部可设有便于锁定端120从解锁面211滑动至锁定面212的圆弧面213a，本实用新型V字型结构的第一作用面121和滑动台阶131倾斜作用接触，因此第一作用面121可稳定地圆弧面213a之间接触连接且不发生滑动，保证了锁定连接的稳定性。所述的复位驱动端110 可在装置复位时使弹性件111储能从而使锁定端120从锁定面212滑回至解锁面211。容易想到的是，断路器故障后锁定装置处于锁定状态，此时弹性件111处于释能状态提供锁定端120与锁定面212接触锁定的作用力，若故障排除将锁定装置复位时可通过手动的方式将复位驱动端110下压，此时锁定端120移至解锁面211且弹性件111重新处于储能状态。
执行杠杆1的中部还设有用于与基座3的侧壁孔轴旋转连接的支点安装孔130，所述的支点安装孔内可安装有轴销131。执行杠杆与基座侧壁稳定旋转安装，保证了执行杠杆的锁定端在由复位驱动端驱动时的稳定性，提高了执行杠杆摆动动作的可靠性。特别地，弹性件111可为设置在执行杠杆1端部与基座3之间的弹簧，并且执行杠杆1一端的底部设有用于限位固定弹簧的圆台112。弹簧结构简单且安装方便，不仅提高了锁定装置的安装效率，同时保证了装置锁定及复位时的稳定性。
如图3所示本实用新型压板2的结构示意图，所述的压板2安装在基座3内的支架4上，压板2的两侧分别延伸设有锁定部210和接触部220，压板2的中部设有与磁通5对应设置的驱动部240，所述驱动部240还延伸出旋转安装部230，所述旋转安装部230对应压板2的两侧分别设有可与支架4孔轴旋转连接的安装圆台231，断路器故障时磁通5可推动驱动部240使压板2沿安装圆台231并相对于支架4向下摆动。压板的结构设计简单且压板安装在基座的支架内，保证了压板旋转摆动时的可靠性。特别地，所述的锁定部210包括相邻设置的解锁面211和锁定面212，并且所述解锁面211与锁定面212之间设有滑动台阶213。特别地，所述滑动台阶213的顶部设有可与锁定端120底部滑动接触的圆弧面213a。圆弧面使锁定端从解锁面滑至锁定面的过程更为轻松流畅，保证了执行杠杆锁定压板的动作不会发生失效，提高了装置的可靠性。并且所述的锁定部210上还设有与压板2一侧壁对应设置的挡板214，并且挡板214对应锁定面212的端部与压板2的侧壁之间设有连接挡板215，所述的连接挡板215、挡板214、压板2的一侧壁以及滑动台阶213的一侧壁共同构成了可与锁定端120对应设置的槽结构216。挡板可用于定位锁定端，防止在锁定过程中锁定端失效提高了锁定装置的稳定性，同时锁定面四周形成有封闭结构的槽结构，提高了锁定时的可靠性。此外，所述的接触部220为L型结构 包括相互垂直连接的水平挡板221和竖直挡板222，所述的竖直挡板222垂直于压板2的一侧壁上，水平挡板221与压板2的侧面平行，所述的水平挡板221可随压板2旋转摆动从而阻挡操作机构的分闸半轴恢复至最高位置即可合闸位置。L型的接触部结构简单便于加工安装，并且水平挡板可有效阻挡操作机构复位提高了锁定装置工作性能。
如图4所示本实用新型初始状态的正面结构示意图，执行杠杆1通过轴销131安装在基座3一侧，执行杠杆1的锁定端120与安装在支架4上的压板2的锁定部210接触连接。本实用新型的初始状态即断路器未发生故障从而锁定装置未触发锁定时，压板2处于水平位置从而接触部220未能阻挡操作机构的分闸半轴正常合闸。如图5所示图4虚线内沿A-A方向的部分结构剖视图，初始状态时执行杠杆1的复位驱动端110的弹性件111处于储能状态，执行杠杆1另一端的锁定端120置于解锁面211内，并且锁定端120的第二作用面122靠在滑动台阶213对应解锁面211的一侧壁上。
如图6所示本实用新型锁定状态的正面结构示意图，所述的安装圆台231上安装有可驱动压板2回至初始位置的复位弹簧232，并且所述复位弹簧232的两端分别与压板2和支架4连接。锁定端从锁定面退回到解锁面时压板可在复位弹簧的复位作用力下带动接触部回到初始位置从而使操作机构的分闸半轴可恢复至最高位置即可合闸位置，保证了复位后压板可回到准确的初始位置，提高了装置的工作准确性。本实用新型的锁定状态即断路器发生故障从而锁定装置触发锁定时，磁通5推动压板2克服复位弹簧232的回复力相对于支架4顺时针摆动旋转，并且执行杠杆1的锁定端120将锁定部210锁定，进而接触部220随压板2顺时针摆动至可阻挡操作机构的分闸半轴恢复至最高位置即可合闸位置。如图7所示图6虚线内沿B-B方向的部分结构剖视图，锁定过程中由于滑动台阶213随压板2摆动使得第二作用面122失去支撑从而锁定端120在弹性件111释能的作用力下滑至锁定面212内完成锁定，锁定状态时作用端123与锁定面212接触同时锁定面212、第一作用面121以及滑动台阶213的一侧可形成三角形结构。特别地，滑动台阶213对应第一作用面121的一侧设有可与第一作用面121匹配接触连接的斜面213b，斜面213b与锁定面212之间为钝角。滑动台阶一侧设置的斜面使得第一作用面与滑动台阶的作用接触面积 增大，防止了接触面之间发生滑动脱落，保证了压板得到有效地锁定。V型结构的锁定端使得第一作用面121与滑动台阶是倾斜接触的，斜面213b的设置可有效保证接触的稳定性。如果第一作用面121与滑动台阶不是倾斜接触的，则斜面213b反而会使锁定端更加易于脱落。在经过用户排除断路器故障，并确认无误对锁定装置解锁时，可手动按下复位驱动端110使弹性件111重新储能同时锁定端120离开锁定面212，压板2失去锁定端120的锁定后在复位弹簧232的回复力作用下恢复初始位置，此时锁定端120重新置于解锁面211内完成复位。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本实用新型的保护范围。
