The utility model discloses a bypass operation trolley capable of being used to replace a distribution transformer without cutting off power. The bypass operation trolley capable of being used to replace the distribution transformer without cutting off the power comprises a chassis, a low-voltage fast-connecting connector, a high-voltage fast-input connector and a high-voltage fast-output connector. A low-voltage switch cabinet, a high-voltage switch cabinet and a transformer are arranged on the chassis. The low-voltage fast-connecting connector is connected with the low-voltage switch cabinet through a first low-voltage cable, the low-voltage switch cabinet is connected with the transformer through a second low-voltage cable, the transformer is connected with the high-voltage switch cabinet through a first high-voltage flexible cable, the high-voltage switch cabinet is connected with the high-voltage fast-input connector through a second high-voltage flexible cable, and the high-voltage switch cabinet is connected with the high-voltage fast-output connector through a third high-voltage soft cable. According to the bypass operation trolley capable of being used to replace the distribution transformer without cutting off the power, a transport trolley frame is used, flexible dispatching is facilitated, cross-area rush-repair work is achieved, and the bypass operation trolley capable of being used to replace the distribution transformer without cutting off the power has strong adaptability and high application ability.
