Train neutral section passing switch assembly switching method, neutral section passing method, switching device and neutral section passing device

Abstract

The invention discloses a train neutral section passing switch assembly switching method, a neutral section passing method, a switching device and a neutral section passing device, which belong to thetechnical field of neutral section passing, and are used for solving the technical problem of low neutral section passing reliability at present. A combination of position detection and current detection is adopted, a train is detected to enter or leave a passing neutral section through a position detection part, the position of a pantograph is detected through current changes of a common sectionof the neutral section, switching of all switch assemblies is controlled through time delay, and therefore the train can smoothly pass through the neutral section without power failure. The whole technical scheme has the advantages of being simple, reliable, accurate in detection, easy to implement, low in cost, free of interference sources and the like.

Description

technical field [0001] The invention mainly relates to the technical field of over-phase separation, in particular to a switching method for a train over-phase-separation switch assembly, a method for over-phase separation, a switching device and an over-phase-splitting device. Background technique [0002] The electrified railway traction power supply catenary is a special single-phase power supply network. In order to ensure that the terminal voltage of the catenary is not lower than the minimum operating voltage of the train, it is generally necessary to install an electric phase splitting device every 20-30km. The continuous improvement of traffic volume and running speed requires the train to run continuously in the neutral zone of the electric separation phase. In order to improve the ability of train over-phase separation, reduce the speed loss of trains during the period of over-phase separation and avoid problems such as out-of-phase short circuit, the current autom...

Problems solved by technology

The principle of this detection method is relatively simple, but the radar detection distance is short, the echo signal is weak, and it is easily interfered by adjacent signal sources, and its reliability is relatively low under all-weather conditions.

[0012] In each of the above technical solutions, when the train enters the phase-splitting area, it is not possible to determine whether the pantograph of the train is raising the front bow or the rear bow, so it is necessary to extend the length of the non-electric zone of the neutral section to adapt to various lifting bows of the train In extreme cases, such as when there is no electricity or a fault in the neutral section, the longer the no-electricity zone, especially when the line is on an uphill section, the train cannot leave the long-distance neutral section due to a drop in speed or a stop due to power failure. sexual zone, which can easily cause line block or paralysis
