Three-column type amorphous alloy dry-type grounding transformer

A three-column type amorphous alloy dry-type grounding transformer in the technical field of a power system comprises a grounding transformer frame, an iron core, insulation cylinders, high voltage coils, a winding connection lead, a device body cushion block and a pressure nail, wherein three high voltage coils and three insulation cylinders are sheathed on the iron core in sequence from the outside to the inside, the high voltage coils are connected through the winding connection lead, and the upper ends and the lower ends of the high voltage coils are fixedly arranged on the grounding transformer frame through the device body cushion block and the pressure nail. The three-column type amorphous alloy dry-type grounding transformer adopts a rectangular amorphous alloy iron core and a high voltage winding with a sectional type rectangular structure, greatly reduces the no-load loss of the product, improves the work efficiency of the product, and saves the energy consumption.
