The invention relates to a subway overhead line system direct current power supply integrated device, and the device comprises a device body, and a first switch module, a second switch module and a cross-zone load switch are arranged in the device body. The first switch module comprises a first isolation switch, and the second switch module comprises a second isolation switch. The first isolationswitch and the second isolation switch are both three-station isolation switches and are provided with three independent stations including a closing station, a separating station and a grounding station. According to the subway contact network direct-current power supply integrated device and method, the contact network isolation switch closing state, the contact network isolation switch openingstate and the contact network isolation switch grounding state are all remotely visible, the isolation fracture image intelligent recognition function is achieved, and large bilateral mode switching can be conducted with loads without affecting driving; external interlocking is avoided, internal interlocking is simple, and misoperation can be effectively prevented; the device is safe, reliable andlow in cost.
本发明涉及一种地铁接触网直流供电一体化装置,包括装置的主体,主体内设置有第一开关模块、第二开关模块及越区负荷开关;第一开关模块包括第一隔离开关,第二开关模块包括第二隔离开关;第一隔离开关和第二隔离开关均为三工位隔离开关,具有三个独立工位,包括:合位、分位和接地位。本发明提供了一种地铁接触网直流供电一体化装置及方法,其接触网隔离开关合位、分位、接地状态均远程可视,具有隔离断口图像智能识别功能,且可以带负荷进行大双边模式切换而不影响行车;无外部联锁,内部联锁简单,可有效防止误操作;设备安全可靠、成本较低。
