Abstract
A converter radiating structure of an explosion-proof instrument comprises a shell, an instrument transformer and a heating element arranged inside the shell. The utility model is characterized in that: the shell is internally provided with a metal radiating body; a heat conducting and inflaming retarding resin is filled between the metal radiating body and the instrument transformer; heat conducting insulating gaskets which are closely stuck and fixed mutually are arranged between the metal radiating body and the heating element as well as between the metal radiating body and the shell.
