The invention provides an electronic switch full-standby main circuit and a ground automatic neutral section passing system and method, and relates to the technical field of train ground automatic neutral section passing. According to the invention, the first switch valve group, the second switch valve group and the corresponding isolating switches are arranged and can be selected according to a user, or when one of the switch valve groups breaks down, the corresponding isolating switches are turned on and turned off respectively, so that the use and standby exchange among the switch valve groups can be realized. After the main circuit is put into operation, the ground automatic neutral section passing performance is not affected, meanwhile, online overhaul and maintenance of an electronic switch full standby scheme and a mechanical switch standby scheme are met, and the working stability of the circuit is greatly improved; the overvoltage generated when the train travels to the neutral region is further absorbed through the overvoltage absorption loop, the stability of a semiconductor device in the neutral region circuit is improved, and the stability of the ground automatic neutral section passing performance is guaranteed.
本发明提出一种电子开关全备用主电路、地面自动过分相系统及方法,涉及列车地面自动过分相的技术领域。本发明设置有第一开关阀组、第二开关阀组和相应的隔离开关,可根据用户进行选择,或者当其中一开关阀组发生故障后,分别导通和关断相应的隔离开关,即可实现开关阀组之间的使用和备用调换。主电路投入运行后地面自动过分相性能不受影响,同时满足了电子开关全备用方案及机械开关备用方案的在线检修与维护,大大提高电路工作的稳定性;本发明进一步通过过电压吸收回路吸收列车行驶至中性区时产生的过电压,提高中性区电路中半导体器件的稳定性,保证地面自动过分相性能的稳定性。
