Description
Technical field
The present invention relates to a kind of electric railway section post automatic neutral-section passing system and automatic passing over of neutral section method thereof.
Background technology
China's electric railway generally adopts single phase industrial frequency AC system, and for making the Three-phase Power Systems balance as far as possible of loading, electric railway often adopts the scheme of rotation phase sequence, phase-splitting switched-mode power supply.Between the adjacent service area at phase-splitting subregion place, with air or insulator, cut apart, form insulated electro phase-splitting, be called for short electric phase-splitting or phase-splitting.
For preventing that electric locomotive is charged, by a minute phase factor arcing, burn out overhead contact line parts, even cause the accidents such as phase fault, the undue phase time of train, driver needs a series of M/Cs, completes phase process, is commonly called as to fall and bends phase-splitting.Along with the lifting of train speed is with too mutually frequent, driver's labour intensity reacts not as good as greatly or manually and cannot complete, must adopt other measure, major measure is for adopting automatic passing over of neutral section technology, as contriver " a kind of electric railway self-monitoring automatic neutral-section passing system and automatic passing over of neutral section method thereof " (application number 201310199444.8), its core is to utilize on contact system the comparison of the electric current that the current transformer that seals near electric segmentation place and the current transformer on electric sectional parallel branch road measure, judging power train is subject to stream situation and this train to arrive the position of electric phase-splitting, by normal open switch, carry out the closed and disconnected of contact system one and contact system two and neutral section, realize the automatic passing over of neutral section of power train.It is suitable for keeping the power train being flowed to cross phase-splitting situation before logical phase splitting.As power train was not flowed before electric phase-splitting, and need to be flowed when arriving neutral section, two switches that now connect neutral section are all in off-state, current transformer cannot detect train and pass through signal, cause train all cannot be flowed by whole neutral section, there is power supply blind area, reduce train speed and traffic potential.Meanwhile, this application, when subregion train automatic passing over of neutral section of living in, still needs the switching action of two switches, and it operates relative complex.
Summary of the invention
The first goal of the invention of the present invention is just to provide a kind of electric railway section post automatic neutral-section passing system, this system can realize under various operating modes electric locomotive in the residing automatic passing over of neutral section of subregion, undue phase time is without the dead electricity time, switching manipulation number of operations is few, structure with control simple, can be more complete, the automatic passing over of neutral section that realizes to safety and reliability electric railway section post.
The present invention realizes the technical scheme that its first goal of the invention adopts, a kind of electric railway section post automatic neutral-section passing system, comprise contact system one, contact system two, neutral section, contact system one is connected with neutral section by electric segmentation one, contact system two is connected with neutral section by electric segmentation two, it is characterized in that:
