The invention relates to the technical field of power
supply and distribution of a power
system, and discloses a separated compact buried box-type substation, which comprises an underground box installed under the ground, a ventilation column installed at the top of the ground, a heat dissipation box and a low-
voltage cabinet installed on the upper surface of the ground, and a wire outlet hole formed in one side of the underground box, a waterproof chuck is installed in the wire outlet hole, a wire outlet
pipe is arranged in the waterproof chuck, the other end of the wire outlet
pipe is communicated with the low-
voltage cabinet, a bridge frame is fixedly connected to the inner wall of one side of the underground box, a
transformer is installed in the underground box, an air inlet hole is formed in one side of the underground box, and an air inlet
pipe is arranged in the air inlet hole. The box-type substation can be split into three independent modules, namely the underground box, theheat dissipation box and the low-
voltage cabinet, free and flexible combination and installation are realized, the limitation of
a site is avoided, the high-voltage cabinet does not need to be configured on site, only the low-voltage cabinet and the ventilation column which occupy extremely small ground are left on the ground part, and the occupied area is reduced.
