Abstract

The present invention relates to an energy-absorbing device for double-stream manufacturing vehicles. The energy-absorbing device includes a first voltage output device and a second voltage output device; the output end of the first voltage output device is connected with a voltage comparator; The output end of the described voltage comparator is connected with a rectifier; the output end of the described rectifier is connected with an energy absorbing resistor; the output end of the second voltage output device is connected with a three-phase to single-phase converter; The energy device is also provided with a transformer; the output end of the transformer is connected to the rectifier; the output end of the transformer is also provided with a transformer connector; the output end of the transformer connector is connected to the input end of the voltage comparator. Its advantages are as follows: when the vehicle is braking, the energy generated by the return line in the catenary, after being stepped down by the transformer, is transmitted to the energy-absorbing resistor for absorption through the rectifier, effectively preventing the current from feeding back power to the grid through the return line, It meets the power requirements of the grid and has good safety.

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...
