Mortise and tenon joint type transformer iron core clamping piece

Abstract

The invention provides a mortise and tenon joint type transformer iron core clamping piece which comprises a clamping piece pressing plate and side beams, and the clamping piece pressing plate and theside beams are connected in a mortise and tenon joint manner to form a firm frame structure. The iron core clamping piece has the characteristics that the clamping force is stronger, and the formed frame structure is firmer and is not easy to loosen.

Description

technical field [0001] The invention belongs to the technical field of transformer components, in particular to a mortise and tenon type transformer core clip. Background technique [0002] The transformer core is composed of a core body, a coil, a core clamp, and an insulator. The core includes a core column and an iron yoke. The core clamp is used to clamp the iron yoke and compress the coil wound on the core column. The core clip is usually detachably connected by two clips and two connecting plates, usually using bolts. [0003] However, there are many shortcomings in the existing connection methods. For example, during the working process of the transformer, the bolts will loosen, causing the coil to fall off during the working process, resulting in short-circuit impact; the bolt connection uses metal parts, and it is easy to form a sharp discharge during use. cause partial discharge. In order to prevent this damage, an insulator should be added between the core clamp...
