Problems solved by technology

[0002] At present, silicon steel sheets in transformers mostly use high-silicon steel sheets, which have good magnetic properties, but are relatively brittle. Usually, additional protective measures are required, which increases the cost of use. Therefore, the structure of silicon steel sheets can be improved.

Abstract

The invention discloses a silicon steel sheet for a transformer, comprising a plurality of superimposed silicon steel sheet bodies and fixing bolts, and is characterized in that: the silicon steel sheet body is provided with a positioning groove and a plurality of fixing through holes, and the positioning groove There is a strip-shaped shock-absorbing pad, a ring-shaped shock pad is arranged on the side wall of the fixing through hole, and the fixing bolts connect the silicon steel sheet bodies together through the corresponding fixing through-holes. The invention has novel structure, shock absorption design, good anti-break effect and strong practicability.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a silicon steel sheet for transformers with novel structural design. Background technique [0002] At present, silicon steel sheets in transformers mostly use high-silicon steel sheets, which have good magnetic properties but are brittle in texture. Usually, additional protective measures are required, which increases the cost of use. Therefore, the structure of silicon steel sheets can be improved. Contents of the invention [0003] In view of the above technical problems, the present invention provides a silicon steel sheet for transformers, which has a novel structure, a shock-absorbing design, good anti-fracture effect, and strong practicability. [0004] The technical solution adopted in the present invention is: a silicon steel sheet used for transformers, including several superimposed silicon steel sheet bodies and fixing bolts, characterized in that: the silicon s...
