摘要
传统巡视和检修方式在铁路低压配电线路上效率低下,无法实时监测变压器的运行状态。为解决这一问题,提出了一种远程控制低压配电线路隔离开关的方法。首先,介绍了电力固定牵引装置在新朔铁路系统的应用,引入远程控制技术,提高运行机动性;其次,对电气化火车站进行电力分区,根据示意图确定控制的隔离开关;然后,确定一次设备的状态感知方法,进而设计隔离开关的远程控制系统;最后,根据所设计的接口继电器面板对隔离开关进行控制,使用PLC对二次电路进行设计并且完成试验验证。结果表明,所设计的隔离开关远程控制系统将提高铁路交通控制的效率和安全性。此外,所提出的方法显著改善了铁路低压配电线路的管理,通过对隔离开关的状态感知,提高隔离开关的可靠性、安全性和运行效率。
The traditional inspection and maintenance methods are inefficient on railway low-voltage distribution lines and cannot monitor the operating status of transformers in real-time.To address this issue,this study proposes a method for remotely controlling low-voltage distribution line isolation switches.Firstly,the application of electric fixed traction devices in the Xinshuo Railway system was introduced,and remote control technology was introduced to improve operational mobility.Secondly,the electrified train station is divided into power zones and the isolation switches for control are determined based on the schematic diagram.Then,first determine the state perception method of the equipment,and then design a remote control system for the isolation switch.Finally,control the isolation switch based on the designed interface relay panel,use PLC to design the secondary circuit,and complete experimental verification.The results indicate that the isolation switch remote control system designed in this article will improve the efficiency and safety of railway traffic control.In addition,the method proposed in this article significantly improves the management of railway low-voltage distribution lines,improving the reliability,safety,and operational efficiency of isolation switches by sensing their state.
