description The invention relates to a direct-current feeder screen, and belongs to the technical field of substations. The direct-current feeder screen comprises an intelligent switch module, the intelligent switch module comprises a miniature circuit breaker for controlling and monitoring a primary side direct-current loop, the feeder screen further comprises a maintenance bypass, the maintenance bypass is arranged in the primary side direct-current loop and connected with the miniature circuit breaker in parallel, and the maintenance bypass comprises a jack. The jacks are used for being connected with maintenance plug-ins, when the maintenance plug-ins are inserted into the jacks, the maintenance bypass is switched on, normal direct-current power supply is not affected under the condition that the switch module is switched on and switched off at will, the direct-current loop can be maintained without electrification under the condition that the direct-current loop is not powered off, and then upgrading and reconstruct
