Embodiment Construction
[0026] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
[0027] Figures 1A-1B It is a structural schematic diagram of a railway catenary pressure difference elimination system provided by an embodiment of the present invention. Such as Figures 1A-1B As shown, the catenary is divided into a first catenary segment and a second catenary segment due to electrical segmentation, and the elimination system includes: a first vacuum contactor 1 and a control device 2, wherein the first vacuum contactor The device 1 is connected between the first catenary section and the second catenary section; the control device 2 is connected with the vacuum...

The embodiment of the invention provides a railway overhead line system differential pressure elimination system and method and a machine readable storage medium, which belong to the field of railways. The overhead line system is divided into a first overhead line system section and a second overhead line system section due to electric segmentation. The elimination system comprises a first vacuumcontactor and a control device, and the first vacuum contactor is connected between the first overhead line system section and the second overhead line system section; the control device is connectedwith the vacuum contactor and is used for acquiring the position of a train; and when the train approaches, the first vacuum contactor is controlled to be switched on so as to communicate the first overhead line system section and the second overhead line system section, and when the train leaves, the first vacuum contactor is controlled to be switched off so as to disconnect the first overhead line system section and the second overhead line system section. Electric arcs caused by the pantograph of the train can be avoided, and dangers are prevented.
Description
technical field [0001] The present invention relates to the field of railways, in particular to a system, method and machine-readable storage medium for eliminating pressure difference of railway catenary. Background technique [0002] In order to significantly increase the railway transportation capacity, this will require the improvement of railway-related equipment capabilities. As far as the catenary on the line is concerned, more current is required to provide running locomotives. In the reconstruction project of the line catenary, in order to reduce the cost of equipment technical transformation, it is proposed to adjust the original power supply interval to the power supply mode of dividing the power supply section into two, and adopt the method of strengthening the power supply line to supply power to the second half of the catenary. Program. However, due to the unavoidable voltage difference at the catenary section of this scheme, if effective voltage balancing me...
