Indoor single-phase large-capacity electromagnetic voltage transformer

An indoor single-phase large-capacity electromagnetic voltage transformer comprises a base body, a protective cover, screws with cheese heads and sealing holes, a base plate and a high voltage primary terminal and is characterized in that the base body, the protective cover, the screws with the cheese heads and the sealing holes, the base plate and the high voltage primary terminal are assembled according to a structure and form a complete-sealing pillar-type whole. The base body is formed by vacuum pouring of a transformer body, a ball head embedded nut, a secondary protective cover embedded nut and a grading ring by adopting red epoxy resin mixture. The transformer body is fixedly formed by a U-shaped iron core, a concentric cylinder-type secondary winding sleeved on the core column of the U-shaped iron core, a primary winding with well welded primary leads and clamping elements of the transformer body by stainless steel throat locks.
