Auto-passing phase separation apparatus and method for electric locomotive

Abstract

The invention discloses an automatic neutral-section passing device and a method for an electric locomotive and solves the technical problems of making the electric locomotive pass through neutral sections safely. A reader of the device is arranged on the electric locomotive and connected with a neutral-section passing device arranged on the electric locomotive. When the electric locomotive passes through a phrase-change point, the reader is wirelessly connected with an electronic tag for communication. The method comprises the following steps: when the electric locomotive passes through the phrase-change point, the reader acquires and decodes position and control information sent by the electronic tag and sends data to the neutral-section passing device on the electric locomotive for the neutral-section passing device to carry out neutral-section passing operation. Compared with the prior art, the device and the method adopt ultrahigh frequency communication based on radio frequency identification, have the reader for acquiring information stored in the electronic tag when the electric locomotive passes through the phrase-change point, have the neutral-section passing device of the electric locomotive for sending a corresponding control signal according to the content of the information, thereby making the electric locomotive pass through neutral sections automatically, and are adaptive to a speed of more than 300km / h of the electric locomotive.

Description

Technical field [0001] The invention relates to an automatic control device and method for an electric locomotive, in particular to an automatic phase passing device and method for an electric locomotive. Background technique [0002] On electric traction railway lines, the power provided by the power system is three-phase alternating current, but the catenary must provide single-phase alternating current to the electric locomotive. In order to make the catenary obtain the current balance from the three-phase AC grid, the catenary adopts the method of segmented and phased to obtain the current. In this way, the catenary is divided into different phase sections, and the interconnected phase sections are powered by different two phases. When the electric locomotive passes through these catenary phase separation areas, if there is a heavy electrical load, when the pantograph crosses the insulation section of the adjacent two phases, arcing will occur, which will burn the catenary an...

AI Technical Summary

Problems solved by technology

A little negligence will lead to electrification and phase splitting, resulting in a short circuit between phases, burning out the insulating phase splitter, and causing accidents

With the continuous improvement of train speed, the running time of trains in an insulating phase separation section is reduced, especially for high-speed railways. If the traditional manual phase separation method is still used, the driver's reaction and operation time will be reduced, and mistakes will cause accidents. greatly increased likelihood
