Iron core loosening internal stress change reducing assembly for environment-friendly transformer protection

The invention relates to the technical field of transformer protection, and discloses an iron core loosening internal stress change reducing assembly for environment-friendly transformer protection. The assembly comprises an iron core, the iron core is fixedly mounted in a fixed table, and the fixed table is mounted at the inner side of a clamping port; the clamping port is fixedly connected with a silicon steel sheet, the outer side of the silicon steel sheet is provided with a gap bin, and the gap bin is movably arranged at the inner side of the extrusion protruding block. According to the iron core loosening and internal stress change reducing assembly for protecting the environment-friendly transformer, a wire at the outer side of a plugging block is electrified, and then current passes through the surface of a change block under the action of current, so that the magnetic poles of the change block are changed to be same as the magnetic poles at the opposite sides of a fixed magnetic block under the action of the current and a coil, and the fixed magnetic block drives a linkage block and a pull rod to move towards the inner side under the action of repulsion of magnetic poles, and then the pull rod drives a transverse pressing block to make contact with the fixed table, and accordingly the loosening phenomenon of an iron core is limited, and the fault rate of the transformer is reduced.
