The invention belongs to the technical field of traction power supply of electrified railways, and particularly relates to a power fusion device for a traction power supply section station of an electrified railway. Compared with an existing power fusion device, the power fusion device is mainly additionally provided with a transformer and a single-phase PWM rectifier, but compared with the existing power fusion device, when the same power is transmitted, the capacity of the transformer and the capacity of a converter can be reduced to be lower than 1/2 of the original capacity, the equipment and construction cost of the fusion device is reduced, and the power fusion device is suitable for popularization and application. The loss reduction amplitude is not less than 65.5%, and the efficiency of the power fusion device is improved.
本发明属于电气化铁道在牵引供电技术领域,具体的说是涉及一种电气化铁道牵引供电分区所功率融通装置。本发明相对于现有功率融通装置,主要是增加了一个变压器和一个单相PWM整流器,但是与现有的功率融通装置相比,传送相同功率时,本发明可以将变压器和变流器容量降到原来的1/2以下,降低了融通装置的设备和建设成本,损耗降低幅度不低于65.5%,提高了功率融通装置效率。
