一种基于电压电流信息检测列车位置的地面带电过分相系统

A Type of Ground Energized Passing of Neutral Section System based on Inspection of Train Location by Voltage and Current Information

过分相是困扰电气化铁路供电的一大难题,本文提出一种地面带电自动过分相系统,通过牵引网的电压电流量检测获得受电弓的位置,进而控制电子开关的动作。本文介绍了该系统智能分相器的电路结构、开关时序、受电弓位置检测原理和电子开关的切换控制逻辑。

Passing of neutral section is a difficult problem existed in power supply for electrified railway,the paper puts forward a type of ground energized passing of neutral section system,which is also called intelligent phase break,is able to obtain the location of pantograph by inspection of voltage and current quantity of traction network and control the action of electronic switches.The paper introduces the circuit structure,switching time sequence,position inspection principle for pantograph and train,as well as the switching control logic of the electronic switches of the intelligent phase break of the system.
