Abstract
The invention relates to an iron core of a large-power reactor. The iron core comprises an iron core body. The iron core body is characterized in that the iron core body comprises multiple rectangular iron core units which are circumferentially and uniformly arranged, and the multiple rectangular iron core units form an annular array structure and are fixed through an iron core fixing mechanism. The iron core body with the annular array structure is composed of the rectangular iron core units which are circumferentially and uniformly arranged, so that the heat radiation area and heat radiation space of the iron core can be increased, and the heat generated by the iron core of the reactor can be reduced. Rubber plates are arranged in air gaps of the rectangular iron core units, so that a damping effect is achieved, and the inductance value of the reactor is convenient to adjust. The iron core fixing mechanism is made of stainless steel materials, so that a heating phenomenon of the iron core fixing mechanism due to magnetic leakage can be prevented.
