The invention relates to the technical field of neutral section passing, in particular to a ground electrified automatic neutral section passing main wiring system and a switching method.The ground electrified automatic neutral section passing main wiring system comprises a third switching unit, a first switching unit and a second switching unit, the first switching unit is arranged between a switch QS1 and a high-voltage switch V1, the second switching unit is arranged between a switch QS2 and a high-voltage switch V2, and the third switching unit comprises a switch QF3 and a switch QF6; when a high-voltage switch V1 and a high-voltage switch V2 break down, a switch QF3 and a switch QF6 can be controlled to be switched off or switched on for standby application, so that after the high-voltage switch breaks down, the third switching unit is switched on to replace work of the A-phase switch unit and the B-phase switch unit, and power failure inspection and maintenance of the ground electrified automatic neutral section passing system when the high-voltage switch breaks down are avoided.
本发明涉及过分相技术领域,具体涉及一种地面带电自动过分相主接线系统及切换方法,包括第三切换单元、设置在开关QS1和高压开关V1之间的第一切换单元和设置在开关QS2和高压开关V2之间的第二切换单元,第三切换单元包括开关QF3和开关QF6,使得在高压开关V1与高压开关V2故障时能够通过控制开关QF3与开关QF6的断开或闭合作为备用,从而使得高压开关故障后第三切换单元闭合代替A相开关单元与B相开关单元的工作,避免高压开关故障时地面带电自动过分相系统停电检查检修。
