定位器是电气化铁路接触网系列设备中的重要部件,是保持接触线正常工作状态的关键设备之一。快速、高速电气化铁路对定位器提出了很高的要求。北京首铁科技工程公司在借鉴国外高速铁路同类产品的基础上,结合我国实际情况研制开发了JlD-3系列多功能定位器。该装置在技术研究和开发上实现了创新和发展(获国家专利),并通过了铁路行业质量检测。该装置适用于200km/h以上电气化铁路,目前在京郑、朔黄、京秦等线路上推广使用,运用状况良好,为保证既有线路安全可靠及高速电气化铁路的发展提供了
The locator is an important part in the series equipment of the electrified railway contact net and is one of the key equipment for keeping the contact line in normal working condition. Fast, high-speed electrified railways place high demands on the positioner. Based on the similar products of high-speed railway in foreign countries, Beijing First Rail Technology Engineering Co., Ltd. developed the JlD-3 series multi-function positioner with the actual situation in our country. The device in the technical research and development to achieve innovation and development (by the national patent), and adopted the railway industry quality testing. The device is suitable for electrified railway above 200km / h. It is currently being used on the lines of Jingzheng, Shuohuang, Jingqin, etc. and is in good condition. It is provided to ensure the safe and reliable operation of existing lines and the development of high-speed electrified railway
