[0002] A transformer, also known as an instrument transformer, is a general term for current transformers and voltage transformers, which is a device used to convert high voltage and large current into low voltage and small current, and is used for measurement or protection systems. During the production of transformers, a protection box is needed to protect the iron core components.

[0003] In the prior art, a Chinese patent with the publication number CN104599812A discloses a transformer housing, which includes a housing. A hollow hole groove for installing the primary current copper sheet of the transformer is formed in the middle of the housing. The hole groove is roughly in an inverted water droplet shape. At least one first rack is provided at the top of the inner wall of the hole groove, and at least one serrated second rack is formed by the inward depression of the side wall of the hole groove. The length of the hole groove is equal to the diameter of the inner arc of the primary current copper sheet, and the height of the hole groove is equal to the radius of the outer arc of the primary current copper sheet. It is integrally injection-molded, with a simple structure, which simplifies the manufacturing process, reduces the manufacturing cost, makes the overall product more beautiful and tidy, and correspondingly improves the electrical performance of the transformer, and the economic benefits are more obvious.
