Description

自动展开式高压互感器现场检定车 技术领域
本发明涉及电力领域，特别是涉及一种自动展开式高压互感器现场检定车。
背景技术
在本发明提出之前，一般的高压互感器现场检定车包括驾驶室和车厢，车厢内通过轨道滑动安装有移动平台，车厢的后车门背面铺设有可与车厢内的轨道对接的轨道，该移动平台上安装有各种试验用仪器和设备(如GIS式试验变压器与标准电压互感器总成等，其中GIS为Gas Insulation Switchgear的缩写，中文译为“气体绝缘开关装置”，也称为“全封闭组合电器”)。该检定车使用时：首先，将后车门打开，并使后车门上的轨道与车厢内的轨道对接；然后，将移动平台移动到后车门上的轨道上(由于传统GIS式试验变压器与标准电压互感器总成为直套管结构，所以必须使GIS式试验变压器与标准电压互感器总成完全移出车厢外即移动平台完全移动到后车门上，才能保证GIS式试验变压器与标准电压互感器总成的均压环完全露于车厢外)；接着，在本车的周围圈围一圈工作安全区域；最后，便可开始互感器的现场计量检定试验。该检定车在使用过程中存在以下问题：
1、由于试验现场通常需要调整移动平台与被试品之间的位置，所以每次调整位置，都需要将移动平台和后车门全部收起后再展开，工作效率极低；
2、后车门上的轨道与车厢内的轨道对接非常费时且可靠性差；
3、由于移动平台上的各种试验用仪器和设备重量较大，所以后车门容易受压变形；
4、由于传统GIS式试验变压器与标准电压互感器总成为直套管结构，所以该总成的高度较高，从而导致车厢的高度也很高，影响了行车安全及车辆的通过性。
发明内容
本发明的目的是为了克服上述背景技术的不足，提供一种工作效率高且可靠性好 的自动展开式高压互感器现场检定车。

本发明与现有技术对比，充分显示其优越性在于：
1、通过将所述试验变压器与标准电压互感器总成的绝缘套管斜向布置，这样，所述移动平台与移动车厢的配合即可将所述绝缘套管上端的均压环移出车厢外，而无需额外在后车门上铺设将所述试验变压器与标准电压互感器总成整体移出车厢外的轨道，从而解决了因需调整移动平台与被试品之间的位置而导致的工作效率低的问题；
2、由于无需在后车门上铺设将所述试验变压器与标准电压互感器总成整体移出车厢外的轨道，所以本检定车不存在轨道对接费时和可靠性差以及后车门容易受压变形的问题；
3、通过采用卧式试验变压器和卧式标准电压互感器，并将两者竖直叠放安装，减小了所述试验变压器与标准电压互感器总成的横向尺寸，从而缩短了本检定车的整体长度；同时，通过将所述绝缘套管斜向布置，减小了所述试验变压器与标准电压互感器总成的高度，从而降低了本检定车的整体高度；
4、通过优化所述绝缘套管的倾斜角，使其即能保证所述均压环能完全移出车厢外，又能保证本检定车的试验安全性，同时进一步地减小了所述试验变压器与标准电压互感器总成的横向尺寸，缩短了本检定车的整体长度；
5、加设的支撑安装件保证了所述试验变压器与标准电压互感器总成的安装稳固性；

如图1所示，本实施例提供一种自动展开式高压互感器现场检定车，包括驾驶室1、车厢2和电力互感器检定系统，所述车厢2后部设有可沿所述车厢2前后滑动的移动车厢3，所述移动车厢3后部设有后车门4，所述车厢2与所述移动车厢3之间的收纳空间 包括试验区2a和操作区2b，所述试验区2a和操作区2b之间通过滑门中隔断11隔开，所述操作区2b内安装有控制柜5，所述试验区2a内沿所述检定车前后方向滑动安装有移动平台6，所述电力互感器检定系统包括电压互感器校验仪器7，所述电压互感器校验仪器7又包括试验变压器与标准电压互感器总成7a、补偿电抗器7b、互感器校验仪7c、电压负载箱7d和调压器7e，所述互感器校验仪7c、电压负载箱7d和调压器7e分别安装在所述控制柜5内，所述试验变压器与标准电压互感器总成7a和补偿电抗器7b分别安装在所述移动平台6上，所述试验变压器与标准电压互感器总成7a包括卧式试验变压器7a1、卧式标准电压互感器7a2和带均压环7a3的绝缘套管7a4，所述卧式标准电压互感器7a2安装在所述卧式试验变压器7a1的顶部，所述绝缘套管7a4斜向安装在所述卧式试验变压器7a1的端部。通过将所述试验变压器与标准电压互感器总成7a的绝缘套管7a4斜向布置，这样，所述移动平台6与移动车厢3的配合即可将所述绝缘套管7a4上端的均压环7a3移出车厢2外，而无需额外在后车门4上铺设将所述试验变压器与标准电压互感器总成7a整体移出车厢2外的轨道，从而解决了因需调整移动平台6与被试品之间的位置而导致的工作效率低的问题；同时，由于无需在后车门4上铺设将所述试验变压器与标准电压互感器总成7a整体移出车厢2外的轨道，所以本检定车不存在轨道对接费时和可靠性差以及后车门容易受压变形的问题；而且，通过采用卧式试验变压器7a1和卧式标准电压互感器7a2，并将两者竖直叠放安装，减小了所述试验变压器与标准电压互感器总成7a的横向尺寸，从而缩短了本检定车的整体长度；再且，减小了所述试验变压器与标准电压互感器总成7a的高度，从而降低了本检定车的整体高度。
上述试验变压器与标准电压互感器总成7a为GIS式试验变压器与标准电压互感器总成，即所述卧式试验变压器7a1采用卧式GIS式试验变压器。
上述绝缘套管7a4的倾斜角为15～75°，该角度范围即能保证所述均压环7a3能完全移出车厢2外，又能保证本检定车的试验安全性。所述均压环7a3位于所述绝缘套管7a4的上端，所述绝缘套管7a4的下端与所述卧式试验变压器7a1的端部相连。

上述绝缘套管7a4与所述卧式试验变压器7a1之间通过端部支筒7a6连接固定。所述端部支筒7a6包括相互配合的上端部支筒7a6a和下端部支筒7a6b，所述下端部支筒7a6b设置在所述卧式试验变压器7a1的端部，所述上端部支筒7a6a设置在所述绝缘套管7a4的下端，所述上端部支筒7a6a和下端部支筒7a6b之间通过法兰方式密封连接。
上述卧式试验变压器7a1底部和所述端部支筒7a6下部分别通过支撑安装件7a7固定安装在所述移动平台6上，该支撑安装件7a7保证了所述试验变压器与标准电压互感器总成7a的安装稳固性，该支撑安装件7a7的数量和布置位置可根据实际需要设计。
上述电力互感器检定系统还包括电流互感器校验仪器8，所述电流互感器校验仪器8又包括标准电流互感器装置8a、升流器8b和电流负载箱8c，所述标准电流互感器装置8a和升流器8b分别通过滑动托盘安装在所述检定车底部的附件箱9内，所述电流负载箱8c安装在所述控制柜5内。
上述检定车底部的四角处分别设有调平支撑腿10，所述调平支撑腿10分别与所述检定车的供电系统连接，所述检定车的供电系统可以为本检定车的蓄电池或额外增设的蓄电池，也可直接采用外接电源。本检定车只需设置四个调平支撑腿10即可保证所述移动平台6的水平度，水平调节更简单方便。
本检定车可在所述操作区2b内安装双人转椅和工作台面等，以方便试验人员试验操作。本检定车还可在驾驶室1与车厢2之间的驾驶侧设置爬梯，在车厢顶面设置围栏，以方便试验人员接线与检修。本检定车还可加设辅助系统，如车内照明灯、场地照明灯、升降照明灯、视频监控系统、顶置冷暖空调、呼唱系统、电动电缆盘(电源线和地线)等。
通过以上配置，使得本检定车可以安全、准确、快捷、高效的完成互感器现场检定的电压和电流试验。
本发明进行互感器现场检定电压试验时：
首先，将本检定车底部的四个调平支撑腿10伸出至地面，并自动调整长度使本检定车底板保持水平；然后，打开后车门4并固定；接着，向车头方向滑动移动车厢3，并向车尾方向滑动移动平台6，直至绝缘套管7a4上端的均压环7a3完全露出并到达试验安全距离；最后，进行试验接线和试验操作，完成互感器现场检定电压试验即可。
本发明进行互感器现场检定电流试验时：
首先，打开装有标准电流互感器装置8a和升流器8b的附件箱9的门板；然后将装载有标准电流互感器装置8a和升流器8b的滑动托盘从所述附件箱9内拖出；最后，进行试验接线和试验操作，完成互感器现场检定电流试验即可。
本发明通过将所述试验变压器与标准电压互感器总成7a的绝缘套管7a4斜向布置，这样，所述移动平台6与移动车厢3的配合即可将所述绝缘套管7a4上端的均压环7a3移出车厢2外，而无需额外在后车门4上铺设将所述试验变压器与标准电压互感器总成7a整体移出车厢2外的轨道，从而解决了因需调整移动平台6与被试品之间的位置而导致的工作效率低的问题；由于无需在后车门4上铺设将所述试验变压器与标准电压互感器总成7a整体移出车厢2外的轨道，所以本检定车不存在轨道对接费时和可靠性差以及后车门容易受压变形的问题；通过采用卧式试验变压器7a1和卧式标准电压互感器7a2，并将两者竖直叠放安装，减小了所述试验变压器与标准电压互感器总成7a的横向尺寸，从而缩短了本检定车的整体长度；通过将所述绝缘套管斜向布置，减小了所述试验变压器与标准电压互感器总成的高度，从而降低了本检定车的整体高度；通过优化所述绝缘套管7a4的倾斜角，使其即能保证所述均压环7a3能完全移出车厢2外，又能保证本检定车的试验安全性，同时进一步地减小了所述试验变压器与标准电压互感器总成7a的横向尺寸，缩短了本检定车的整体长度；加设的支撑安装件7a7保证了所述试验变压器与标准电压互感器总成7a的安装稳固性；本检定车只需设置四个调平支撑腿10即可保证所述移动平台6的水平度，水平调节更简单方便。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
