Title:
INTELLIGENT ELECTRIC PHASE SPLITTING DEVICE FOR ALTERNATING-CURRENT ELECTRIFIED RAILWAY
Document Type and Number:
WIPO Patent Application WO/2017/005017
Kind Code:
A1
Abstract:
An intelligent electric phase splitting device for an alternating-current electrified railway comprises a first switch (6) for connecting a first power supply arm (1) and a phase splitting zone (3) and a first impedor (4) connected therewith in parallel, a second switch (7) for connecting the phase splitting zone (3) and a second power supply arm (2) and a second impedor (5) connected therewith in parallel, a sensor for detecting the current and the voltage of the first switch (6), a sensor for detecting the current and the voltage of the second switch (7), and the like. The device can automatically recognize the position of a pantograph (11) of a train by using information about the voltage of two ends of a first switch (6) and a second switch (7) and information about the current flowing through the first switch (6) and the second switch (7), and can automatically switch on or off the first switch (6) and the second switch (7) according to the recognized position of the pantograph (11), thereby enabling a phase splitting zone (3) to obtain or cut off electric energy of power supply arms (1, 2); and a circuit structure of the switches (6, 7) and impedors (4, 5) connected therewith in parallel can be replaced by a circuit structure that two ends of step-down transformers (9, 10) and low-voltage windings (9b, 10b) thereof are connected to the switches (6, 7). The device is not required to install a train position detection mechanism on a track, the structure is simple, and the use and the maintenance are convenient.
