The invention discloses an explosion-proof manufacturing process for a voltage transformer, which comprises the following steps of: concentrically winding a secondary winding and a primary winding on an insulating framework, winding the primary winding in two stages, adding an electrostatic screen outside each stage, sleeving an iron core with the wound primary winding after winding, forming a coil device body after insulation and buffer binding, and fixing the coil device body in a pouring mold, a primary insert is fixed after a primary lead is wound into a spring shape, a shielding net is fixed by a mold core mold, the primary insert is wound and connected together by adopting a bare copper wire, a secondary wiring terminal is connected, an insulation distance is adjusted, and epoxy resin is adopted for vacuum pouring and curing to form an integrated structure, so that a main insulator is formed; an explosion-proof device is installed on the top of the main insulator, if heat generated by the primary windin
