The invention discloses an integrated metro overhead line system switching device which comprises at least two overhead line isolation switches and at least one cross-zone isolation switch, and every two adjacent overhead line isolation switches are connected through one cross-zone isolation switch. The network access isolation switch comprises a first underframe, a first moving contact, a first static contact, a grounding contact, a wire inlet row and a first transmission mechanism. The cross-zone isolation switch comprises a second underframe, a second moving contact, a second static contact and a second transmission mechanism. The two networking isolation switches and the cross-zone isolation switch are integrated, an integrated device is provided, debugging and assembling are completed when leaving a factory, the workload and the working difficulty of on-site workers are reduced, a three-station networking isolation switch is used for replacing a two-station networking isolation switch, a complex electrical interlocking relation is avoided, the grounding process of the power loop is simplified, and the safety of the power loop is improved.
本发明公开一种集成式地铁接触网切换装置,包括:至少两个上网隔离开关和至少一个越区隔离开关,每相邻两个上网隔离开关之间经一个越区隔离开关连接;上网隔离开关包括第一底架、第一动触头、第一静触头、接地触头、进线排以及第一传动机构,越区隔离开关包括第二底架、第二动触头、第二静触头以及第二传动机构。通过集成两个上网隔离开关和越区隔离开关与一体,提供集成式装置,在出厂时完成调试和拼装,减小现场工作人员的工作量和工作难度,用三工位上网隔离开关替代两工位上网隔离开关,避免复杂的电气联锁关系,简化电力回路的接地过程、提升电力回路的安全性。
