Instrument observation hole, one side of the housing is installed with an inspection door, a transformer is installed in the housing and the lower part of the control room, a partition is installed in the control room, a primary terminal is installed on the upper part of the partition, and a control line wiring is installed on the partition and the lower part of the primary terminal Terminals, moving wheels are installed at the bottom of the transformer, and the four corners of the transformer are connected with the bottom plate of the housing by bolts. The two outer sides of the bottom of the transformer in the length direction are installed with movable frames, and the length of the movable frame is equal to the length of the transformer. There are 3 primary terminals and 5 control terminals. A protective cover is installed outside the top of the casing, and the control room is arranged on the upper surface of the protective cover. The upper end of the control room is provided with an instrument chamber cover and a wiring chamber cover, and the first small cable entry room, the second small cable entry room and the third small cable entry room are arranged side by side on the rear side wall of the control room.

The utility model has the advantages that: on the partition plate of the control room, connecting terminals are set so that all electrical components in the controller are connected through the connecting terminals, and the connecting terminals can be set according to the explosion-proof requirements, so that the explosion-proof performance of the charger is further improved. A moving wheel is set at the bottom of the transformer, and the bottom plate set at the bottom of the transformer is connected with the bottom plate of the charger casing by bolts, so that when the transformer is being maintained, the transformer can be moved outside the charger casing for maintenance only by breaking off the bolts , so that the maintenance is simple and fast, without damaging the transformer.
