The invention relates to the technical field of power transmission, in particular to a main circuit of a traction substation. The traction substation main circuit comprises a traction transformer, a rectifying device and an inversion device, the input end of the traction transformer is connected with a power system; the traction transformer is used for converting three-phase electricity of the power system into two-phase electricity and transmitting the two-phase electricity to the rectifying device; the rectifying device is used for converting the two-phase power into direct current and transmitting the direct current to the inverting device; and the inversion device is used for converting the direct current into alternating current required by the traction network and transmitting the alternating current to the traction network. The system is used for overcoming the defects that in the prior art, when an AC-DC-AC traction substation is used for solving the problems of electric energy quality and electric phase splitting, the transformation difficulty is large, cost is high, and adaptability is poor, high-reliability power supply is provided for a traction network, and the adaptability of the AC-DC-AC traction substation is enhanced while the problems of electric energy quality and electric phase splitting are solved.

    本发明涉及电力传输技术领域,尤其涉及一种牵引变电所主电路。该牵引变电所主电路包括牵引变压器、整流装置和逆变装置;牵引变压器的输入端连接电力系统;牵引变压器,用于将电力系统的三相电转换为两相电,并将两相电传输给整流装置;整流装置,用于将两相电转换成直流电,并将直流电传输给逆变装置;逆变装置,用于将直流电转换成牵引网所需的交流电,并传输给牵引网。本发明用以解决现有技术中交直交牵引变电所为解决电能质量和电分相问题时,改造难度大、成本高、适应性差的缺陷,实现为牵引网提供高可靠供电,在解决电能质量和电分相问题的同时,增强交直交牵引变电所适应性。
