s2, leading high temperature generated by open fire into the mounting hole through the heat conduction pipe (12), melting the soluble barrier block (17) in the mounting hole at the high temperature, and mixing the effervescent disintegrant (16) in the longitudinal hollow bracket (11) with the aqueous solution (15) in the transverse hollow bracket (14) to release carbon dioxide;
s3, when external impact is caused, the transformer body (4) extrudes the carbonic acid solution (19) in the interception net (18), so that the carbonic acid solution (19) expands in the interception net (18), and the impact force between the transformer body (4) and the supporting frame (2) is reduced;
s4, when open fire occurs in the transformer body (4), the burning residues in the transformer body (4) are intercepted through the expanded intercepting net (18), and more serious fire caused by the dropping of the residues is effectively prevented.
