一种断路器，包括外壳以及至少两个断路器极，在所述外壳内还设置有如上所述的试验按钮回路装置，试验回路的一端与一个断路器极的进线端连接，试验回路的另一端与另一个断路器极的出线端连接。
优选的，所述试验按钮回路装置与断路器的手柄机构设置于外壳的上部，导电件转动装配于手柄机构与弹性按钮之间，在导电件远离弹性按钮的一侧有设置试验电阻。
本发明的一种试验按钮回路装置，试验回路仅具有一个由接触部与导电件 形成的断点，随着断路器的分合闸使导电件联动，在合闸时，按压弹性按钮可以接通试验回路，在分闸时，按压弹性按钮无法导通试验回路，使其具备双断点结构的保护效果，能够防止反接线带来的分闸后带电问题，又具有单断点结构的结构简单、装配效率高以及可靠性高的优点。
此外，导电件转动安装，通过导电件的第二端随断路器的分合闸动作摆动，通过调整导电件的第二端与接触部之间的距离，使接触部在合闸时与导电件的第二端配合接触，在分闸时无法接触，进一步简化其结构，提高可靠性。
此外，在外壳设置限位槽，由限位槽限制导电件的第二端运动轨迹，提高接触部与导电件的配合程度。
此外，通过第一限位部、第二限位部配合限制弹性按钮的按压行程，避免弹性按钮按压行程过长造成操作不便，同时也保证在分闸状态下，弹性按钮无法与导电件的第二端接触。
本发明的断路器，采用结构简单、安全性高的试验按钮回路装置，简化了断路器的装配难度，利于缩小断路器的体积。

具体实施方式
以下结合附图1至5给出的实施例，进一步说明本发明的一种试验按钮回路装置和断路器的具体实施方式。本发明的一种试验按钮回路装置和断路器不限于以下实施例的描述。
一种试验按钮回路装置，包括形成试验回路的弹性按钮和导电件4，弹性按钮包括与导电件4配合的接触部511以及按压接触部511的按钮件52，导电件4与断路器的手柄机构12或操作机构13或动触头141联动，在断路器合闸时， 断路器的手柄机构12或操作机构13或动触头141驱动导电件4靠近接触部511，此时按下按钮件52驱动接触部511移动能够与导电件4接触以导通试验回路；在分闸时，断路器的手柄机构12或操作机构13或动触头141驱动导电件4远离接触部511，此时按下按钮件52驱动接触部511移动也无法与导电件4接触。
本发明的一种试验按钮回路装置，试验回路仅具有一个由接触部511与导电件4形成的断点，随着断路器的分合闸使导电件4联动，在合闸时，按压弹性按钮可以接通试验回路，在分闸时，按压弹性按钮无法导通试验回路，使其具备双断点结构的保护效果，能够防止反接线带来的分闸后带电问题，又具有单断点结构的结构简单、装配效率高以及可靠性高。
结合图1-5提供一种断路器的实施例，所述断路器包括外壳，在外壳内并列设置有至少两个断路器极1，每个断路器极1包括设置于两端的接线端子11，两个接线端子11形成断路器的接线端，具体由其中一个接线端子11作为进线端，另一个接线端子11作为出线端，相邻两个断路器极1的进线端(出线端)位于同一侧。另外，每个断路器极1可以单独设置相极外壳，由所有相极外壳拼装形成断路器的外壳，或者，相邻两个断路器极1通过隔板2分隔，由一个底座、一个上盖以及至少一个隔板2共同形成断路器的外壳。
至少在其中一个断路器极1还设置有手柄机构12、操作机构13、触头机构、灭弧系统15、短路保护机构16和过载保护机构17，如图4所示，所述手柄机构12与操作机构13联动连接并设置于该断路器极1的上部，触头机构包括相互配合的动触头141和静触头142，动触头141连接于操作机构13的下部，静触头142、灭弧系统15固定于该断路器极1的中部，动触头141、静触头142分别与两个接线端子11连接，短路保护机构16设置在手柄机构12与灭弧系统15之间，过载保护机构17设置于一个接线端子11与动触头141之间，短路保护机构16的一端以及过载保护机构17的活动端分别与操作机构13相对，在发生短路或过载故障时触发操作机构13脱扣。
具体的，所述操作机构13包括转动装配的杠杆，在所述杠杆上转动装配有跳扣、锁扣131和触头支持，在跳扣与手柄机构12之间连接有连杆，跳扣与锁扣131的一端搭扣配合，短路保护机构16的一端与锁扣131的另一端相对，在锁扣131的另一端还连接有脱扣挂钩，所述脱扣挂钩与过载保护机构17的活动 端相对，动触头141通过触头支持连接在杠杆上，在本实施例中，锁扣131通过凸轴132转动连接在杠杆上，凸轴132的一端凸出且可以穿过设置在隔板2或相极外壳上的避让孔伸入相邻断路器极1内，使相邻两个断路器极1的锁扣131由凸轴132联动。
如图1-3、5所示，在本实施例的一个断路器极1内还设置有试验按钮回路装置，所述试验按钮回路装置贴合该断路器极1的隔板2设置，试验按钮回路装置包括形成试验回路的弹性按钮、试验电阻3以及导电件4，试验回路的一端与一个断路器极1的进线端连接，另一端与另一个断路器极1的出线端连接，在该断路器极1的隔板2上部设置有供弹性按钮滑动装配的按钮孔，优选按钮孔与该断路器极1的手柄机构12并列设置于隔板2的上部，导电件4转动装配于手柄机构12与弹性按钮之间，试验电阻3设置在导电件4远离弹性按钮的一侧，也就是将试验电阻3设置于手柄机构12的下方，导电件4通过试验电阻3与断路器的一个接线端连接，导电件4的第一端41与操作机构13联动，具体由锁扣131的凸轴132与导电件4的第一端41联动，使导电件4的第二端42随断路器的分合闸进行摆动，弹性按钮包括与断路器的另一个接线端电连接的接触部511以及按压接触部511的按钮件52，在本实施例中，试验电阻3的一端焊接于一个断路器极1的出线端子，弹性按钮的接触部511通过导线与另一个断路器极1的进线端子连接。相比现有双断点试验按钮回路结构，本实施例的试验按钮回路装置结构简单，充分利于内部空隙设置，占据空间较小，利于断路器的小型化设计。
如图2、3所示，在手柄机构12与弹性按钮之间的外壳内侧壁(也就是在隔板2的侧壁)设置有限位槽21和限位凸台22，其中限位槽21为设置在手柄机构12一侧的弧形槽，导电件4的第二端42在限位槽21内进行摆动，以提高导电件4与弹性按钮的配合程度；所述限位凸台22对应于限位槽21的上方，使接触部511沿限位凸台22进行滑动，图2、3中限位凸台22与限位槽21的上侧边缘衔接。当然，省略限位槽21和/或限位凸台22也同样适用。另外，在弹性按钮与外壳内侧壁之间还设置有相互配合的第一限位部23和第二限位部524，在按压弹性按钮时，通过第一限位部23和第二限位部524配合以限制弹性按钮的按压行程，避免弹性按钮的按压行程过长不便操作，也可以防止试验 回路在分闸状态被导通，当然，通过控制弹性按钮的弹性形变量，或者控制接触部511与导电件4的第二端42之间间距同样可以避免分闸状态下导通试验回路。
结合图2、3和5提供一种导电件4的结构，所述导电件4包括扭簧，所述扭簧的主体43转动装配于隔板2上，优选在隔板2上设置有供主体43转动连接的连接轴或连接槽，试验电阻3的一端与扭簧的主体43连接，主体43的两端分别向主体43两侧的方向延伸形成导电件4的第一端41和导电件4的第二端42，图2、3中导电件4的第一端41向弹性按钮的方向延伸，导电件4的第一端41末端弯曲形成环状结构，锁扣131的凸轴132伸入环状结构内带动导电件4转动，导电件4的第二端42向手柄机构12的方向延伸，导电件4的第二端42末端弯折朝向外壳一侧，优选导电件4的第二端42末端伸入限位槽21内与限位槽21滑动配合。
如图2、3所示，所述弹性按钮包括被按钮件52按压的导电弹簧51，所述导电弹簧51的一端通过导线与一个作为进线端的接线端子11连接，导电弹簧51的另一端向一侧延伸形成接触部511，图中接触部511向手柄机构12的方向延伸并对应于导电件4的第二端42的上方。
所述按钮件52包括一体成型的操作部521、连接部522以及按压部523，所述操作部521与外壳的按钮孔滑动配合并伸出外壳，连接部522以及按压部523连接在操作部521位于外壳内的一端，连接部522沿平行于按钮孔的中心轴线的方向延伸并与导电弹簧51的一端连接以按压导电弹簧51，按压部523沿垂直于按钮孔的中心轴线的方向延伸，按压部523与接触部511限位配合用于按压接触部511，优选在按压部523设有与接触部511卡合的凹槽结构，在按压部523的中部凸出设有作为第二限位部524的凸台。
在断路器合闸时，如图3所示，手柄机构12以及操作机构13顺时针转动，锁扣131的凸轴132带动导电件4的第一端41向下转动，导电件4的第二端42沿限位槽21向上摆动，此时导电件4与接触部511之间的距离最小，此时按下弹性按钮，导电弹簧51被压缩，按压部523向下按压接触部511，使接触部511与导电件4的第二端42接触以导通试验回路；在分闸时，如图2所示，手柄机构12以及操作机构13逆时针转动，锁扣131的凸轴132带动导电件4的第一 端41向上转动，导电件4的第二端42沿限位槽21向下摆动，此时导电件4的第二端42远离接触部511，此时按下按钮件52，即使接触部511被向下按压，但是由于接触部511与导电件4的第二端42之间距离较远以及第一限位部23、第二限位部524对弹性按钮行程的限制，使接触部511无法与导电件4的第二端42接触，使试验回路不被导通。
当然，在本实施例中，试验回路中还可以设置其他断点。
提供本申请的另一个实施例，所述断路器与上述实施例相同，断路器包括外壳以及至少两个断路器极1，在其中一个断路器极设置有与上述实施例相同的试验按钮回路装置，与上述实施例所不同的是，导电件4的第一端41与断路器的动触头141联动，使导电件4的第二端42随动触头141的分合闸动作而摆动，从而调节导电件4的第二端42与接触部511之间的距离。
提供本申请的又一个实施例，所述断路器与上述实施例相同，断路器包括外壳以及至少两个断路器极1，在其中一个断路器极1设置有与上述实施例相同的试验按钮回路装置，与上述实施例所不同的是，导电件4的第一端41与断路器的手柄机构12联动，使导电件4的第二端42随手柄机构12的分合闸摆动而摆动，从而调节导电件4的第二端42与接触部511之间的距离，优选在本实施例中，导电件4的第一端41设置在靠近手柄机构12的一侧，导电件4的第二端42设置在靠近弹性按钮的一侧，接触部511的长度可以适当缩短。
当然，在上述三个实施例中，导电件4也可以采用其他形状的结构，例如导电杆，或者其他形状的弹性件，例如片簧等，另外，锁扣131的凸轴132、动触头141、手柄机构12或其他断路器的动作机构与导电件4的联动可以是直接联动，也可以是间接联动。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
