The compact transformer substation is in a triangle array, that is, the transformer is integrated with the HV device and the LV device inside the box, which are separated by metal plates to make the HV side, the LV side (including measurement and reactive power compensation) and the transformer relatively independent and related to each other as an organic whole of a complete power distribution substation.
The HV side can adopt the pressure-operated load switch, the vacuum load switch or the SF6 load switch, while the LV side adopts various ACBs and MCCBs; the transformer is fully airtight and exposed. The substation adopts natural ventilation and cooling.
