The invention provides a control circuit and a control method for passing neutral section continuous power supply of an electric locomotive, belongs to the technical field of traction power supply, and solves the problem of hidden dangers existing in power-off operation when the electric locomotive passes neutral section in the prior art. Comprising a first power supply traction network, a second power supply traction network and a traction network neutral section located between the first power supply traction network and the second power supply traction network, and a primary side of a first transformer is connected in series between the first power supply traction network and the traction network neutral section; a primary side of a second transformer is connected in series between the second power supply traction network and the traction network neutral section; the secondary side of the first transformer is connected with a first change-over switch, and the secondary side of the second transformer is connected with a second change-over switch; the traction network can continuously supply power to the electric locomotive in the split-phase region, so that the effect that the electric locomotive passes through the split-phase region without power failure is achieved, and the hidden danger that the locomotive stops in the split-phase region is eliminated.

    本发明提供一种电力机车过分相连续供电的控制电路及控制方法,属于牵引供电技术领域,解决了现有技术中电力机车过分相时断电运行存在的隐患问题;包括第一供电牵引网、第二供电牵引网和位于二者之间的牵引网中性段,在第一供电牵引网和牵引网中性段之间,以串联方式接入有第一变压器的一次侧;在第二供电牵引网和牵引网中性段之间,以串联方式接入有第二变压器的一次侧;所述第一变压器的二次侧连接有第一切换开关,所述第二变压器的二次侧连接有第二切换开关;本发明使牵引网在分相区也能对电力机车进行连续供电,从而实现电力机车不断电过分相的效果,消除机车停运于分相区的隐患。
