Abstract

The invention relates to an energy absorption device for a double-current system vehicle. The energy absorption device comprises a first voltage output device and a second voltage output device; the output terminal of the first voltage output device is connected with a voltage comparator; the output terminal of the voltage comparator is connected with a rectifier; the output terminal of the rectifier is connected with an energy-absorbing resistor; the output terminal of the second voltage output device is connected with a three-phase-to-single-phase converter; the energy absorption device is further provided with a transformer. The output terminal of the transformer is connected with the rectifier; the output terminal of the transformer is also provided with a transformation joint; and the output terminal of the transformation joint is connected with the input terminal of the voltage comparator. The device has the advantages that when a vehicle is braked, energy generated on the overhead line system through the return line is subjected to voltage reduction through the transformer and then is transmitted to the energy absorption resistor through the rectifier to be absorbed, the current is effectively prevented from feeding back power to a power grid through the return line, the power utilization requirement of the power grid is met, and safety is good.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an energy-absorbing device for dual-flow vehicle manufacturing. Background technique [0002] With the development of urban and rural construction, there is an urgent need to establish a fast track connecting "central cities" and "suburban cities". The scope of urban rail transit continues to expand, and urban railways for connecting central cities and satellite cities and between satellite cities have emerged as the times require. At present, AC25kV has been successfully applied on high-speed railway lines, and the technology has reached the international leading level. The integration on the same train can meet both DC power supply and AC power supply. However, there are following defects and deficiencies in the dual-stream car manufacturing in the prior art: [0003] First of all, in the dual-current manufacturing vehicles in the prior art, the return line is grounded a...
