Dry-type transformer for safe operation of power distribution system

The utility model discloses a dry-type transformer for safe operation of a power distribution system, which relates to the technical field of transformers and comprises a protective shell, a sealing door is movably sleeved outside the protective shell, a threaded rod is movably sleeved inside the protective shell, and a movable base is sleeved outside the threaded rod in a threaded manner. A threaded rod is fixedly installed on the top of the movable base, and rolling wheels which are evenly distributed are arranged at the bottom of the movable base. According to the dry-type transformer for safe operation of the power distribution system, through cooperative use of an air pump, a communicating pipe and an air exhaust connector, after the protective shell and the sealing door are closed, the air pump can be started, and the air pump exhausts air in the protective shell and the sealing door through the communicating pipe and the air exhaust connector; therefore, open fire is prevented from being generated when
