Abstract

The invention discloses a motor train unit subsidiary loop split-phase passing uninterruptible power supply device which comprises a pantograph, a main circuit breaker, a transformer, a traction motor, a four-quadrant rectifier, a static inverter and a subsidiary current converter, wherein a subsidiary load of a motor train unit is powered from the middle direct current loop link and inverted by the subsidiary current converter; and the motor train unit subsidiary loop split-phase passing uninterruptible power supply device ensures that the subsidiary load of the motor train unit is not powered off when passing through a split phase, prevents the frequent start of the subsidiary load, improves the service life of the subsidiary load, eliminates passenger panic and other troubles caused bysuddenly powering off, and the like and improves the comfort and satisfaction of passengers.

Description

technical field [0001] The invention belongs to the technical field of complete rail transit equipment, in particular to an uninterrupted power supply device for over-phase separation of an auxiliary circuit of an EMU. Background technique [0002] Since the railway traction catenary uses a single power frequency alternating current, in order to balance the three-phase load of the power system and improve the utilization rate of the power grid, it is required that the electrified railway catenary is powered by segments and phases. Segmentation becomes phase separation. When passing through the phase-splitting area, the EMU needs to disconnect the main breaker or the input side of the main and auxiliary converters, and the pantograph will pass through the phase-splitting area in a state of no current. [0003] The structure diagram of the existing traction control system is as follows: figure 1 As shown, including pantograph 1, main circuit breaker 3, transformer 5, tractio...
