Novel alternating current resistor structure

The utility model discloses a novel alternating current resistor structure. A resistance card is formed by winding a manganese-base alloy or nickel-base alloy resistance wire on a skeleton of the resistance card by adopting a non-inductive winding method, wherein the skeleton of the resistance card selects a flat plate which is made of high-frequency porcelain; a plurality of laminated resistance cards are fixed by screw rods, and are encapsulated into a metal shell or a plastic shell coated by a metal film; outgoing lines of the resistance cards are connected with one another in parallel, and have a shielding function; the adjacent resistance cards are isolated by insulating gaskets at the joints of the screw rods; an encapsulation shell of the resistor is provided with four end buttons; two end buttons are connected to the outgoing line at one end of each of the resistance cards which are connected in parallel; the other two end buttons are connected to the outgoing line at the other end of each of the resi
