The utility model discloses a UNL13300 rectification screen with an AC/DC isolation switch. An alternating-current isolating switch, a direct-current isolating switch, a connecting copper bar, a UNL13300 rectifying unit and a screen body frame form a whole. When the UNL13300 rectifying unit breaks down and needs to be overhauled on line, the alternating-current and direct-current isolating switches are sequentially switched off, the faulted rectifying unit is electrically isolated from a main loop, after on-line repairing is completed, the alternating-current and direct-current isolating switches are sequentially switched on, the repaired rectifying screen is put into operation, and the reliability of continuous operation of the excitation system is improved. The utility model has the characteristics of simple structure, convenience in operation, low cost and the like, and the structure of the original UNL13300 rectifying unit is not changed. 本实用新型公开一种带交直流隔离开关的UNL13300整流屏。由交流隔离开关、直流隔离开关、连接铜排、UNL13300整流单元和屏体框架
