前后驱动装置包括横向设于架体 1-1上部的前后驱动气缸 1-501、 与前后 驱动气缸 1-501活动端固接且与架体 1-1横向滑动连接的顶板 1-502, 前后驱 动气缸 1—501的动作带动顶板 1-502在架体 1-1上前后滑动。 前后驱动装置设 有分别与输出侧机械手 1-6及进入侧机械手 1-5固接的两顶板 1-502, 两顶板 1 -502之间通过连杆 1 -512固接，输出侧机械手 1-6及进入侧机械手 1 -5均包括 竖向固接于顶板 1-502且与架体 1-1横向滑动连接的底板 1-503、 缸体固接于 底板 1-503且活动端向下的上下驱动气缸 1-504 (双行程气缸）、 与上下驱动气 缸 1—504活动端连接的安装板 1-505、一端固接在安装板 1-505上且与底板 1-503 竖向滑动连接的上下移动拖板 1-506, 顶板 1-502的前后滑动带动底板 1-503 在架体 1-1上前后滑动使输出侧机械手 1-6及进入侧机械手 1-5同步前后移动， 上下驱动气缸 1-504的动作带动安装板 1-505及上下移动拖板 1-506在架体 1-1 上竖直滑动实现机械手的上下移动。握持部包括固定于安装板 1-505底面的夹 紧气缸 1-507、 分别与夹紧气缸 1-507两活动端连接的两气爪 1-508、 与气爪 1-508外侧面连接的绝缘块 1-509, 绝缘块 1-509外侧螺接一与夹紧气缸 1-507 活动端连接的连板 1-510, 两气爪 1-508的相对侧设有半圓槽形成与穿心铜棒 1-2相配的夹持孔 1-511 ,夹紧气缸 1-507的动作带动连板 1-510、绝缘块 1-509 动作以控制两气爪 1-508的开合度实现握持或松开穿心铜棒 1-2。
为了提高检测效率并避免电流过大而产生的高温，检定系统包括绝缘试验 装置 5绝缘试验和误差检定模块 6, 绝缘试验装置 5和误差检定模块 6均包括 两穿心机构， 一穿心机构包括所述进入侧机械手 1-5、 输出侧机械手 1-6及穿 心铜棒 1-2。 两穿心机构通过一继电器与电源连接， 通过继电器切换实现两穿 心铜棒 1-2依次通过大电流以保证在同一时刻只有一穿心铜棒 1-2通过大电 流， 而另一穿心铜棒 1-2处于待机状态。
在一工装板 1-7装载两母线式电流互感器 1-3 , 三工装板 1-7为一组， 在 输送线 1-4的带动下六个母线式电流互感器 1-3依次穿入或穿出穿心铜棒 1-2, 实现对六个母线式电流互感器 1-3同时检测的目的。 12个母线式电流互感器依 次完成在一绝缘试验装置 5或误差检定模块 6中的检测。
本发明实施例所述互感器穿心铜棒 1-2在中心位置不动， 由输送线 1-4带 着互感器进行穿心。 使得绝缘试验装置 5和误差检定模块 6结构紧凑、 筒单， 穿心成功率高。
由于不同互感器的中心孔和二次绕组的高度都有 4艮大差异，为适应所有类 型的互感器的一次穿心和二次压接，一次穿心机构和二次压接机构具体都可以 采用双行程气缸， 可根据不同尺寸调节运动行程。
参见图 4, 由于被检的各类型互感器穿心孔径和中心高度不同， 若穿心铜 棒 1-2只保持一种高度难以实现对所有类型互感器的一次穿心动作。采用双行 程气缸 1-504, 可带动夹具和一次铜棒在检定输送线体的垂直方向进行位移， 实现一次铜棒具有两个高度位置， 可满足所有类型互感器的一次穿心要求。
待机状态时机械手和穿心铜棒停靠在检定输送线 4体的另一侧，与复匝式 互感器夹具对称布置， 当母线式互感器输送至检定工位前，机械手连同穿心铜 棒一起平移至检定输送线 4中心， 等待并完成一次穿心和一次压接动作。
所述二次接压线机构包括与架体连接的能上下移动的二次接压线上下驱 动组件，二次接压线上下驱动组件下端设有复数个竖直的用于和互感器二次端 连接的导电棒。
如图 16所示， 所述的二次接压线机构 5-7包括与架体 5-1连接的能上下 移动的二次接压线上下驱动组件 5-701 ,所述的二次接压线上下驱动组件 5-701 下端设有复数个竖直的用于和互感器二次端连接的导电棒 5-702。
下面以用于误差试验的二次压线机构为例进行说明。绝缘试验装置 5的二 次压线机构的结构基本相同， 区别为绝缘试验装置 5具有两排导电棒， 绝缘试 验装置 5的两排导电棒分别用于连同峰值电压表和升压源输出端，完成匝间绝 缘试验、 绝缘电阻测试和工频耐压试验， 在此不再详述。
如图 8-10所示， 本发明所述用于误差试验的二次压线机构包括架体 3-1、 设于架体 3-1下方的条状绝缘块 3-2、设于架体 3-1与绝缘块 3-2之间以驱动绝 缘块 3-2上下移动的气缸 3-3 (双行程气缸）、 连接在架体 3-1和绝缘块 3-2上 的导杆 3-12及设于绝缘块 3-2上用于和互感器二次端压接的复数个并排设置 的试验探针 3-4, 试验探针 3-4的上端连接导线。
架体 3-1与绝缘块 3-2之间设有两气缸 3-3 , 两气缸 3-3分设于绝缘块 3-2 的两端， 气缸 3-3的缸体通过连接板 3-5垂直向下安装在架体 3-1的下端面， 气缸 3-3的活动端通过底板 3-6固定在绝缘块 3-2上用于为绝缘块 3-2的上下 移动提供驱动力。
架体 3-1下端面开设两条螺母安装槽， 槽内嵌有螺母块， 连接板 3-5通过 螺釘与螺母安装槽内的螺母块锁紧， 气缸 3-3的缸体通过连接件固定在连接板 3-5的下端面实现气缸 3-3缸体固定在架体 3-1上。
试验探针 3-4外套有弹簧 3-7, 绝缘块 3-2上设有复数个试验探针插孔， 试验探针 3-4中部设用于和弹簧 3-7相抵的凸肩， 试验探针 3-4套接弹簧 3-7 后插入试验探针插孔，试验探针 3-4的下端设外螺纹以与用于和互感器二次端 相抵的铜头 3-8螺接； 弹簧 3-7—端与试验探针 3-4的凸肩相抵， 其另一端与 绝缘块 3-2相抵使绝缘块 3-2下移后试验探针 3-4能与互感器二次端可靠接触。 试验探针插孔的上下端均设有内螺纹以分别与两轴套 3-9的外螺纹螺接；位于 试验探针 3-4上端的轴套 3-9, 其下端面与试验探针 3-4的凸肩之间设有外套 于试验探针 3-4的弹簧 3-7;在待机时，试验探针 3-4的凸肩在弹簧 3-7的弹力 作用下与位于试验探针插孔下端的轴套 3-9抵触。 导杆 3-12上设有并排的 12 个试验探针插孔分别插接 12个试验探针 3-4。 连接架体 3-1和绝缘块 3-2的导 杆 3-12为两个，导杆 3-12的下端通过法兰 3-10固定在绝缘块 3-2上，架体 3-1 上设有用于穿设导杆 3-12的导杆孔， 一导杆孔内设有分别与绝缘块 3-2上、 下端面通过螺釘固接的两滑动轴承 3-11。与试验探针 3-4上端连接的导线接入 互感器校验仪以检测互感器误差试验时的二次绕组电流，铜头 3-8下端设倒角 以避免在压接时与互感器二次绕组中间的绝缘挡块干涉。试验探针 3-4与上端 接接导线共同组成了互感器误差检定所需的二次绕组回路接线， 试验探针 3-4 压接时的接触电阻和上端连接导线的电阻之和为需满足计量检定规程要求的 互感器检定的二次回路阻抗。
二次压接机构可完成六只互感器的二次绕组同时压接，在误差试验过程中 同一互感器二次绕组的两个试验探针 3-4通过继电器短接， 处于短路状态， 通 过依次切换继电器实现六只互感器依次接入互感器校验仪中，按照互感器检定 规程进行误差试验。
参见图 8, 由于被检各类型的互感器二次端子具有两类不同高度， 具体可 以采用双行程气缸 3-3可使试验探针向下运动时具有两个可选行程，根据互感 器类型尺寸的不同，选择合理的行程， 实现所有类型互感器二次绕组端子的可 靠压接。
母线式和复匝式互感器的二次端子位置相同，因此本发明采用同一套二次 绕组压接机构。 绝缘试验装置 5中的二次绕组压接机构具有两排端子， 一排用 于完成绝缘电阻测量和工频耐压试验， 通过继电器切换， 二次端子可输出 DC 500V和 AC 3000V的电压， 而通过在接地端测量泄露电流可测得被检互感器 的绝缘电阻。 另一排端子连接测量装置，但一次绕组通过被检互感器额定电流 时，二次端子测量并监控互感器二次开路产生的峰值电压， 判断互感器匝间绝 缘强度。 测量及监控装置完成互感器一次绕组升流能力、 二次绕组峰值电压、 接地端泄露电流等的测量和监控。误差检定装置布置在检定输送线 4旁，在绝 缘试验装置 5之后， 主要由带升流器的电流互感器、 一次导线、 一次绕组压接 机构、 二次绕组压接结构、 程控电源、 互感器校验仪、 负荷箱等组成。 绝缘试 验装置 5主要完成低压电流互感器的基本误差测量和磁饱和裕度试验项目。误 差检定装置 6中的带升流器的电流互感器、 一次导线、 一次绕组压接机构、 程 控电源都与绝缘试验装置 5相同。其中二次绕组压接机构只有一排端子， 连接 到互感器校验仪中， 用于测量互感器二次绕组的输出电流。 互感器校验仪和负 荷箱都为程控式， 可实现全自动检定功能。
如图 11-图 13所示， 本发明实施例所述互感器在线检测用工装板 (即图 1 中工装板 10 ), 包括底板 4-1 , 所述底板 4-1上装有两能前后位移的档杆 4-2, 处于档杆下方的底板 4-1上装有绝缘垫板 4-3。 所述底板 4-1 中心线上设有两 导轨 4-4, 所述导轨 4-4上滑动连接一滑块 4-5 , 所述滑块 4-5上装有档杆 4-2, 所述导轨 4-4的两侧各装有一绝缘垫板 4-3 ,所述档杆 4-2与绝缘垫板 4-3间隙 配合。 所述滑块 4-5被一气缸 4-6驱动。 所述绝缘垫板 4-3前后边缘位置各开 有一定位孔， 所述底板 4-1上设有与定位孔相匹配的定位销 4-7。 所述绝缘垫 板 4-3中间开有前后向的凹槽 4-8。
工作过程： 当自动化流水线体进行互感器 4-9上料部分， 气缸 4-6将挡杆 4-2退回， 一上料机械手可将互感器箱内互感器 4-9取出， 放在绝缘垫板 4-3 上后， 气缸 4-6伸出， 挡杆 4-2将互感器 4-9浮动卡紧， 然后进入自动化流水 线体进行检测检定工作。
检定管理系统包括任务管理功能模块、输送控制功能模块、检定控制功能 模块、 数据处理及分析功能模块。
任务管理功能模块用于从生产调度平台中获得工作任务，并向仓储系统发 起出库申请， 根据该生产任务对不同检定单元和不同工位进行任务分解。
输送控制功能模块用于触发上、 下料机器人自动上下料、控制输送线体将 被检互感器分配至对应检定工位、完成多套检定装置和多个检定单元的有序上 下料。
检定控制功能模块用于自动完成互感器检定项目所需要的一次绕组和二 次绕组压接动作、 控制升流升压器和测量仪器完成检定项目、 存储误差数据。
数据处理及分析功能模块用于对互感器检定合格与否进行判断、对互感器 检定任务的完成率、 故障率进行分析统计。
参见图 2, 该图为本发明实施例所述互感器全自动化检定系统工作流程 图。 本发明实施例所述互感器全自动化检定系统对应的检定方法包括以下步 骤：
1 )供料步骤。
将互感器从仓储系统的出库口经供料输送线 2传输至上料工位；
2 )上料步骤。
机器人将位于供料输送线 2上的互感器抓取至位于检定输送线 4的工装板 10上， 将工装板 10和对应互感器的条码信息绑定， 记录互感器信息；
3 )外观检查步骤。
工装板 10在检定输送线 4的带动下进入外观检查工位， 相机对互感器进 行拍照，外观检查装置通过所拍的照片与已存储的对应图片进行对比以分析被 检互感器铭牌内容是否完整、 器身是否完好， 并记录；
4 )绝缘试验（预防性试验） 步骤。
工装板 10随着检定输送线 4到达绝缘试验工位， 一定数量的工装板 10 在检定输送线 4的带动下进入对应的绝缘试验工位，绝缘试验工位上的绝缘试 验装置 5对互感器一次绕组、二次绕组进行压接，程控电源输出 380V或 220V 电压至升流器、 升压器， 根据不同的试验项目升流器产生低压大电流、 升压器 产生直流和交流电压，依次完成低压电流互感器的匝间绝缘试验、绝缘电阻试 马全和工频耐压试马全；
5 )误差检定步骤。
绝缘试验完毕，被测互感器跟随检定输送线 4流入误差检定工位，误差检 定工位上的误差检定装置对互感器一次绕组、二次绕组进行压接，程控电源输 出 380V或 220V电压至升流器， 升流器产生低压大电流， 低压大电流通过与 升流器输出端连接的一次导线流经串联的待测互感器一次绕组，通过与二次绕 组压接机构连接的互感器校验仪测量互感器二次绕组的输出电流，完成误差试 验和磁饱和裕度试验， 实现全自动检定， 记录不合格产品；
6 )激光打标步骤。
误差检定完毕， 工装板 10随着检定输送线 4进入激光打标工位， 激光打 标机将在检定合格的互感器器身上刻蚀一段代码。检定不合格的互感器不进行 激光打标， 自动流转入下料工位， 等待异常处理。
所述代码用于标识检定合格、 检定日期、 检定人员等信息；
7 ) 下料步骤。
机器人将位于检定输送线 4工装板 10上的合格的互感器抓取放至位于供 料输送线 2上的箱体中， 装箱后， 箱体随供料输送线 2至仓储系统。
其中，绝缘试验装置 5及误差检定装置 6均分为第一检定单元及第二检定 单元， 一组 12个互感器平分为两小组， 依次进入第一检定单元及第二检定单 元； 绝缘试验装置 5的第一检定单元对 6个互感器通电测试时绝缘试验装置 5 的第二检定单元完成一、 二次绕组的接线， 并处于等待通电测试状态； 待绝缘 试验装置 5的第一检定单元对 6个互感器通电测试完毕，绝缘试验装置 5的第 二检定单元开始通电测试，接着位于绝缘试验装置 5的第一检定单元的 6个互 感器流入误差检定装置 6的第一检定单元， 对 6个互感器接线后通电测试，待 绝缘试验装置 5的第二检定单元对 6个互感器通电测试完毕后流入误差检定装 置 6的第二检定单元的 6个互感器通电测试。
在本技术方案中，分别对母线式及复匝式电流互感器设计有不同的一次接 线机构以满足其不同的接线要求，而二种不同型号互感器因其二次端尺寸一致 因此采用一套二次端子接压线机构。在二次匝间绝缘检定时因为要长时间地通 过大电流因此在一次接线机构中会产生大量的热量，而温升的大幅上升又会降 低大电流导线及机构的使用寿命， 因此在设计本装置时把一批 12个互感器分 成左右两组机构每组 6个工位。以减少每个机构的通电时间并使其有更多的时 间散热。
一、本装置在对母线式电流互感器进行绝缘试验及误差检定时其运作步骤 :¾口下：
1) 检定管理系统软件从生产调度平台获得工作任务，将该任务分解到不 同检定装置的不同表位。 互感器自动化检定装置的检定控制软件获取该任务， 做好相关的准备工作。
2 ) 当检定装置确认本批次检定对象为母线式互感器时， 绝缘试验装置的 第一检定单元的母线式电流互感器一次接线机构推至输送线中间位置，使穿心 铜棒上下高度与前后位置与输送线上的互感器中心孔位置保持一致。 3)当被检互感器在输送线体分拣工位被挡停时，通过身份识别环节确定该 批次互感器应进入的自动化检定装置。
4 ) 自动化检定装置获得输送管理软件发过来的触发信号时， 绝缘试验单 元的进入侧机械手 5-502下端的气爪 5-504松开穿心铜棒， 随后进入侧机械手 5-502上升让出互感器流入通道， 此时穿心铜棒处于单边悬握状态。
5)被检互感器从装置的左面穿入穿心铜棒至检测工位后， 由工位上的档停 机构同时将定位反馈信号传给检定控制软件，检定控制软件接到上述信号后认 为互感器已到达检测工位， 就控制输出侧机械手下降， 气爪 5-504握紧穿心铜 棒。
6)悬挂在第一检定单元上方的二次接压线机构 5-7的二次接压线上下驱动 组件 5-701下降使导电棒 5-702压接互感器二次端。
7)互感器一二次绕组接线结束后检定装置对互感器进行预升流来检测每 个互感器二次端的开路电压， 用于验证互感器一二次绕组接线是否可靠。
8)接线完成后绝缘试验装置上的检定仪器根据检定规程的要求分别对其 进行绝缘电阻.工频耐压.二次匝间绝缘试验， 并将试验结果上传到检定控制软 件。
9)在绝缘试验装置的第一检定单元检测的同时，检定控制软件控制第二检 定单元动作， 其动作过程与第一组母线式电流互感器进入第一检定单元相同， 完成第二组被检互感器的绝缘试验自动接线和自动测试
10)第一检定单元各项检测完成后， 输出侧的机械手下端的气爪 5-504松 开穿心铜棒， 输出侧的机械手上升， 此时穿心铜棒再次处于单边悬握状态， 互 感器向右流出工位。
11)当工位上互感器全部流出后， 输送线上的红外感应器和计数器将反馈 互感器已全部流出铜棒的确认信号，输出侧机械手下降， 其下端的气夹握持穿 心铜棒，接着母线式电流互感器前后驱动组件将整个母线式电流互感器一次接 线机构移离输送带， 放置于安全位置。
12)第二检定单元的互感器完成检测后，其流出过程与第一组互感器相同。
13)第一组互感器在完成绝缘试验后直接流入误差检定装置的第一检定单 元， 第二组互感器在完成绝缘试验后流入误差检定装置的第二检定单元， 两组 互感器流入及流出过程与在绝缘试验装置时相似。 二、本装置在对复匝式电流互感器进行绝缘试验及误差检定时其运作步骤 ：¾口下：
本装置在做复匝式电流互感器时其检定方式与母线式基本一致， 区别在 于： 在复匝式电流互感器进入时， 第一或第二的检定单元的复匝式电流互感器 一次接线机构动作， 而母线式电流互感器一次接线机构不动， 复匝式电流互感 器前后驱动组件向输送带移动， 接着由压接组件 5-602夹持互感器一次侧端， 使复数个互感器一次侧串联。 检定结束后， 压接组件 5-602松开互感器一次侧 端， 前后驱动组件背离输送带， 退出测试工位。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局 限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易 想到的变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护 范围应该以权利要求的保护范围为准。
