The invention discloses a local high-temperature optical change self-reminding type
transformer, and belongs to the field of transformers. According to the local high-temperature optical change self-reminding type
transformer, through the arrangement of a plurality of optical change
mushroom balls, when local heat at cooling fins is high, the heat enters optical change hemispheres along magnetic attraction heat conduction rods, and a
high heat conduction gas is heated to expand; and an air support spacer is pushed to expand towards one side of a ball containing groove, and the expanded air support spacer pulls the opening part of an elastic
pipe so that fluorescent color balls fall into the optical change cavity and are longitudinally distributed, the surface of the optical change
mushroom ball near the position where the heat is locally higher presents a
colored optical spot phenomenon, and therefore the effect of reminding workers is achieved. Working personnel can maintain uneven local
heat distribution in time, and potential safety hazards are reduced. And in addition, after being heated, an
external pressure air core gradually expands to extrude a fluorescent liquid so that the liquid level rises, the light emitting range of the fluorescent color balls is effectively enlarged, and the reminding effect on the workers is remarkably improved.
