The invention discloses an uninterruptible assembled/disassembled mobile distribution transformer. The distribution transformer, a low voltage distribution box and a wood pole are arranged on a flat car. A high voltage fuse and a high voltage lightning arrester are arranged on the wood pole. The upper end of the high voltage fuse is installed on a high voltage phase line through a high voltage lead and an installing line clamp while the lower end of the high voltage fuse is connected with the upper end of the high voltage lightning arrester and the upper end of a high voltage sleeve of the distribution transformer. The lower end of the high voltage lightning arrester is connected with a grounding device. The upper end of a general switch in the low voltage distribution box is connected with the upper end of a low voltage sleeve of the distribution transformer, and the lower end of the general switch in the low voltage distribution box is connected with each branch switch which is used for being connected with electric equipment. The bottoms of the distribution transformer and the low voltage distribution box are respectively grounded through the grounding device. The distribution transformer can be drawn to field for installation and application along a 10-35kV line requiring power, and can be drawn back to a storeroom to be stored when not used, so that the power demand for agricultural irrigation is guaranteed.
