The invention discloses a ground burying type transformer which solves the problem that a radiating effect is poor, water is easy to accumulate in a ground pit, and a cover plate can prevent theft. The ground burying type transformer comprises the ground pit, a transformer body arranged in the ground pit and an overground part arranged at the upper end of the ground pit. The overground part comprises a ventilating window and a cover plate component. The ventilating window comprises a window body arranged on the wall upper end face of the ground pit and defined by a front lateral frame, a rear lateral frame, a left lateral frame and a right lateral frame. The front lateral frame and the rear lateral frame are both divided into a plurality of front window frames and rear window frames. The left lateral frame and right lateral frame are both divided into a plurality of left window frames and right window frames. Stainless steel wire net plates and shutters are arranged on each front window frame, each rear window frame, each left window frame and each right window frame. The cover plate component comprises a left turning cover, a right turning cover, a cover plate anti-falling mechanism and an anti-theft lock. The left turning cover is hinged to the upper end of the left lateral frame through a plurality of anti-theft hinges, and the right turning cover is hinged to the upper end of the right lateral frame through a plurality of anti-theft hinges. The cover plate anti-falling mechanism comprises two left supporting pieces and two right supporting pieces. The anti-theft lock comprises a lock catch base, two lock catches and a padlock.
