Description

隔离开关综合测试仪 技术领域
本发明涉及开关的测试装置技术领域，尤其涉及一种隔离开关综合测试仪。
背景技术
开距：是指当隔离开关分闸到达终止位置后，触头与触指之间的距离。隔离开关的作用是将带电部分隔开，使检修部分有一个明显的断开点，一般情况下，一是，隔离开关触指端或者触头端在隔离开关分闸后一端带电，如果开距不够会造成不带电一侧在空气中被击穿；二是，开距过大或者过小，会影响隔离开关三相的同期和直度，所以开距是在检修中必须检测的项目。
触头：触头与触指座间隙：隔离开关在完全合闸后，触头与触指座之间的距离，即图9中，位置A到位置B之间的直线距离。
隔离开关分合闸同期：隔离开关一般三相为一组，且三相一般有联动的要求，也就是用同一台操动机构操作，使得三相隔离开关同步动作，完成分、合闸，如图10所示。所谓同期，也就是三相开关合闸、分闸是否同步，隔离开关同期不合格将影响电力系统稳定。
隔离开关开距测试技术与方法：目前测量隔离开关开距的方法是靠人工使用卷尺对触头和触指之间的距离进行测量。这种测量方法带来的问题，一是，由于开距数值较大，并且人员高处作业受空间、光照等影响测量精度不够；二是，高电压等级隔离开关绝缘子高度较高，触指和触头都置于绝缘子顶端，并且当高电压等级隔离开关分闸后，触指与触头开距很大，220KV的电压等级隔离开关开距一般在2.5米以上，绝缘子高度在2米以上，人员无法使用卷尺进行测量，使得高电压等级隔离开关开距测量成为盲点，大大影响检修隔离开关的质量。
隔离开关触头与触指座间隙测试技术与方法：目前测量隔离开关触头与触指座间隙的方法是靠人工使用板尺，在隔离开关合闸后的位置对插入深度进行测量，高电压等级隔离开关绝缘子高度较高，220KV的电压等级隔离开关一般绝缘子高度在2米以上，人员无法使用板尺等其他长度测量工具进行测量或者人员高处 作业受空间、光照等影响测量精度不够，使得高电压等级隔离开关触头与触指座间隙测量成为盲点，大大影响检修隔离开关的质量。
隔离开关分合闸同期测试技术与方法：目前测量隔离开关分合闸同期的方法是合闸同期将隔离开关进行合闸，接近合闸终了时，依靠肉眼观察三对触指与触头的距离然后人工使用卷尺对触头和触指之间的距离进行测量，判断合闸同期是否合格；分闸同期将隔离开关进行分闸，接近分闸一半行程时，依靠肉眼观察三对触指与触头的距离然后人工使用卷尺对触头和触指之间的距离进行测量，判断分闸同期是否合格。依靠肉眼观察，测量工具受空间、位置、高度的限制，同时人员作业受空间、光线等严重影响测量精度，并且要求同期不合格数值很小，测量精度不高大大影响检修隔离开关的质量。

如图1-2所示，所述开距与同期测量组件1包括开距测量超声波探头11、分闸同期测试超声波探头12、合闸同期测试超声波探头13、第一数据处理及无线发射模块、固定架组件和第一水平仪15。所述开距测量超声波探头11、分闸同期测试超声波探头12和合闸同期测试超声波探头13与所述第一数据处理及无线发射模块电连接，所述第一数据处理及无线发射模块固定在第一封装盒14内。开距测量超声波探头11、分闸同期测试超声波探头12、合闸同期测试超声波探头13 内嵌在第一封装盒14的一侧，所述固定架组件固定在第一封装盒14的另一侧。所述开距测量超声波探头11与固定架组件垂直，分闸同期测试超声波探头12与固定架组件之间夹角的角度大于合闸同期测试超声波探头13与固定架组件之间夹角的角度。所述固定架组件包括倒“L”型固定框架16和夹紧螺栓17，所述夹紧螺栓17穿透倒“L”型固定框架16的一个侧边并部分进入框架内。所述第一水平仪15固定在所述倒“L”型固定框架16的上表面。
如图3-5所示，所述触头与触指座间隙测量组件2包括位移传感器21、位移传感器固定框架22、固定框架紧固螺栓23、第二数据处理及无线发射模块和第二水平仪26。所述位移传感器21固定在所述位移传感器固定框架22内，所述位移传感器21通过其底部的滑动槽轨25可左右移动的设置在位移传感器固定框架22的内部。所述第二数据处理及无线发射模块与所述位移传感器21电连接，所述第二数据处理及无线发射模块位于第二封装盒24内，第二封装盒24固定在所述框架一条侧边的外侧，所述固定框架紧固螺栓23穿透所述位移传感器固定框架22的一个侧边并部分进入框架内。所述第二水平仪26固定在位移传感器固定框架22上侧的外部。
开距与同期测量组件共三个，分别安装于隔离开关的A、B、C三相触指端导电臂上，夹在导电臂上后，使用组件上的水平仪校正，然后拧紧夹紧螺栓完成固定。触头与触指座间隙测量组件共三个，分别安装于隔离开关的A、B、C三相触指的防雨罩上，夹在触指的防雨罩上后，使用组件上的水平仪校正，然后拧紧紧固螺栓完成固定，如图7所示。
在触头与触指座间隙测量组件的位移传感器固定框架底部，开有一个滑动槽轨，位移传感器可沿着滑动槽轨左右滑动调整位移传感器的位置，以适应不同厂家和电压等级的隔离开关，当位移传感器位置调整好以后，拧紧位移传感器紧固螺丝完成调整。
位移传感器是触头与触指座间隙测量组件的核心部件，对于测量触头与触指座间隙的位移传感器进行了单独设计。通过松动量程调整紧固螺丝29，可使位移传感器的测量杆左右滑动进行量程调整。通过松动位移传感器测量杆高度调整紧固螺丝，可使位移传感器测量触头上下滑动进行高度调整，以适应不同厂家 和电压等级的隔离开关。
数据接收分析终端是隔离开关综合测试仪的主要部分，结构如图6所示。在开距与同期测量组件和触头与触指座间隙测量组件的启动按钮按下后，再按下数据接收分析终端的启动按钮后，数据接收分析终端与开距与同期测量组件和触头与触指座间隙测量组件通过数据处理及无线发射模块进行无线通讯。
数据接收分析终端的触摸屏上设有图形化操作界面，在程序设计上共分为三个模块，主体是测量工作模块，附件模块是查看历史记录模块和终端设置模块。按下数据接收分析终端启动按钮后，首先通过数据处理及无线发射模块和测量部分中的开距与同期测量组件和触头与触指座间隙测量组件进行通讯连接，当连接好以后进入欢迎提示接面，如果出现连接通讯故障或者测量部分的启动按钮没有打开则出现故障提示界面。
测量工作模块：点击测量工作按钮后，进入测量工作模块，首先是变电站和测试设备记录界面，输入完毕后按下确定按钮，完成保存测量设备的信息记录。因为使用仪器时隔离开关要在分闸状态，要在分闸状态安装开距与同期测量组件和触头与触指座间隙测量组件。所以，完成保存测量组件的信息记录后，首先要测量的是隔离开关的开距，进入开距测量界面。
当开距测量结果测出后，与预先编制好的设备参数数据库进行对比，当与相应电压等级相应设备型号的设备比较在设备参数数据库合理的范围内时出现合格界面，假如A相超出合理的范围时出现图不合格界面，重新测量后合格时进入合格界面，按下所有重新测量按钮后进入重新测量界面，不合格时再进入不合格界面。当按下保存结果按钮后，保存开距测量结果并进入合闸不同期测量界面。

按下触头与触指座间隙按钮后进行触头与触指座间隙测量界面。当触头与触指座间隙测量结果测出后，与预先编制好的设备参数数据库进行对比，当与相应电压等级相应设备型号的设备比较在设备参数数据库合理的范围内时出现合格界面，假如A相超出合理的范围时出现图不合格界面，按下所有重新测量按钮后进入图重新测量界面，重新测量后合格时进入合格界面，不合格时再进入不合格界面。当按下保存结果按钮后，保存触头与触指座间隙结果并进入分闸不同期测量界面。
按下测量分闸不同期按钮后进行分闸不同期测量，给出三分之二分闸位置时A相触指和触头的距离、B相触指和触头的距离、C相触指和触头的距离，用以比较哪一相快，哪一相慢，并给出分闸不同期界面。当分闸不同期结果测出后，与预先编制好的设备参数数据库进行对比，当与相应电压等级相应设备型号的设备比较在设备参数数据库合理的范围内时出现合格界面，假如A相超出合理的范围时出现不合格界面，重新测量后合格时进入合格界面，按下所有重新测量按钮进入重新测量界面，不合格时再进入不合格界面。当按下保存结果按钮后，保存合闸不同期结果并进入测量完毕，显示测量结果界面。测量完毕，进入显示测量结果界面后显示测量的详细信息。按下返回功能选择界面，返回最初界面。
<2>查看历史记录模块：测量工作模块记录的数据全部存储在Micro SD卡上，点击查看历史记录按钮，进入查看历史记录模块，读取Micro SD卡上的数据，按箭头按钮翻页。<3>设置模块：设置模块，主要是对时间日期进行设置。
开距测量原理：使用超声波测距原理，当超声波发出探测波，探测波沿直线传播，当遇到障碍物，也就是测量物时，反弹回来，成为接收波，再根据波的传播速度和时间得出距离再除以2。超声波探头也是有一定长度的，设其长度为L头，波的行程设为L1，所以开距L开＝L头+L1，在给数据接收分析终端的程序设计中要考虑超声波探头的长度。
合闸不同期测量原理与开距测量原理一样，也是利用使用超声波测距原理，隔 离开关合闸同期的测量方法是，在合闸过程中，合闸接近终了时(触头与触指距离大约为100mm的分闸位置)A、B、C三相的超声波探测距离设为LA合、LB合、LC合，三个距离互相做差，ΔL合AB＝LA合-LB合、ΔL合BC＝LB合-LC合、ΔL合AC＝LA合-LC合，取ΔL合AB、ΔL合BC、ΔL合AC这三个数绝对值最大的为合闸不同期测试结果。由于合闸不同期是做差得出的数值，所以不用考虑超声波探头的长度。
分闸不同期测量原理与开距测量原理一样，也是利用使用超声波测距原理。隔离开关分闸同期的测量方法是，在分闸过程中，分闸行程约完成三分之二的位置，保持三分之二分闸位置时A、B、C三相的超声波探测距离设为LA分、LB分、LC分，三个距离互相做差，ΔL分AB＝LA分-LB分、ΔL分BC＝LB分-LC分、ΔL分AC＝LA分-LC分，取ΔL分AB、ΔL分BC、ΔL分AC这三个数绝对值最大的为分闸不同期测试结果。由于分闸不同期也是做差得出的数值，所以不用考虑超声波探头的长度。
触头与触指座间隙测量原理，是利用位移传感器所走行程来间接测量触头与触指座间隙的，隔离开关分合闸的方式是触指臂与触头臂以其支柱绝缘子为圆心，绕圆心做90度角转动。触头与触指座间隙测量组件固定在防雨罩上，因为位移传感器的测量杆与两个触指排平行，所以当触头刚接触到位移传感器测量触头开始设为初始位置，如图8所示。在安装所述触头与触指座间隙测量组件时，需要保证位移传感器测量杆的最左端与触指座的最右端相齐平，在隔离开关触头插入过程中，测量杆在触头的作用下向左移动，假设测量杆的整体长度为L测 量杆，通过位移传感器测量的触头插入深度为L触头插入深度，则需要测量的触头与触指座间隙值为L测量杆-L触头插入深度，即图9中A到B之间的直线距离。数据接收分析终端程序设计流程图如图11所示。
所述测试仪包括两个部分，即测量部分和数据接收分析终端。测量部分通过使用超声波探头对隔离开关开距以及分合闸同期进行测量，通过使用位移传感器对触头与触指座间隙进行测量，然后将测量的数据通过数据接收分析终端对其进行处理，得到需要的检测值。在整个测试的过程中，操作人员测量数据非常方便，并且通过使用电子器件，避免了人为操作带来的误差，测量精确度高。
