Amorphous alloy iron core structure used for photovoltaic transformer and capable of preventing heat emission

Abstract

The invention provides an amorphous alloy iron core structure used for a photovoltaic transformer and capable of preventing heat emission, wherein the amorphous alloy iron core structure used for the photovoltaic transformer comprises an amorphous alloy iron core, a silicon steel sheet and a winding, wherein the amorphous alloy iron core is used for conducting magnetism; the silicon steel sheet is arranged at the innermost layer of the amorphous alloy iron core and used for keeping the strength of the amorphous alloy iron core; a plurality of notches are arranged at different positions in the width direction of the silicon steel sheet, such that the section area of the silicon steel sheet is reduced; and the winding is wound on the amorphous alloy iron core and the silicon steel sheet and used for transmitting electric current, such that electric energy is converted into electromagnetic energy. According to the invention, eddy current generated by magnetic leakage in the iron core can be reduced; local overheat faults of the iron core can be eliminated; and simultaneously, the structural strength of the amorphous alloy iron core cannot be destroyed.
