Description

Core winding mandrel

This application claims the priority of a Chinese patent application filed on August 02, 2018 with the Chinese Patent Office, application number 201810870530.X, and the invention name is "wound core mold for iron core", the entire contents of which are incorporated herein by reference. Applying.

Background technique

In transformers, amorphous alloy transformers are widely used because of their significant energy-saving and environmental protection performance. Among them, the core used in amorphous alloy transformers usually uses a three-dimensional triangular amorphous alloy core.

The three-dimensional triangle structure amorphous alloy transformer is assembled by three three-dimensional triangle structure amorphous alloy iron cores. The three-dimensional triangle structure amorphous alloy iron core is a rectangular frame with a semi-circular cross-section. The crystal alloy strip is wound from the inside out. During processing, the winding core mold is used to maintain the winding shape of the core, and the subsequent annealing process is performed with the core. After the core is glued and fixed, the winding core mold is removed, in order to prevent the core from being easily disassembled during disassembly. Deformed, the winding core mold is set as a split core, and adjacent cores are detachably connected. The split butt surfaces of the adjacent cores are sloped, and the connection is achieved through the fastener passing through the split butt surface.

However, when assembling the winding core mold, it is necessary to fix the adjacent cores through the outer limit structure. After positioning, the adjacent cores are fixed by the fasteners, and then the outer limit structure is removed. When assembling, it needs to be fixed and positioned by the outer limit position limiting structure, which results in low assembly efficiency of the winding core mold.
