Abstract

The invention relates to the technical field of power equipment, and particularly discloses a radial iron core cake-based iron core assembly structure. The radial iron core cake-based iron core assembly structure comprises an upper-part fastening fitting, a lower-part fastening fitting, iron core posts and upper-lower fastening bolts, wherein multiple groups of iron core posts are arranged betweenthe upper-part fastening fitting and the lower-part fastening fitting, each group of iron core post is fixedly connected with the upper-part fastening fitting and the lower-part fastening fitting bythe upper-lower fastening bolts, one end of each upper-lower fastening bolt extends out of the upper-part fastening fitting, the other end of the upper-lower fastening bolt extends out of the lower-part fastening fitting, each group of iron core post comprises a plurality of radial iron core cakes, and the plurality of radial iron core cakes of each group of iron core post are arranged in a lamination way. The invention also discloses a reactor. When the radial iron core cake-based iron core assembly structure provided by the invention is applied to the reactor, the loss can be effectively reduced, and the problem of relatively large loss in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of electric equipment, in particular to an iron core assembly structure based on a radial iron core cake and a reactor comprising the iron core assembly structure based on a radial iron core cake. Background technique [0002] Small and medium-sized reactors with a capacity below 12000kvar, the iron core adopts a stacked screw clamping structure, consisting of silicon steel sheets, baffles, air gap spacers, grounding belts, fastening fittings for the yoke, upper and lower pressing fittings and double ends for fixing bolts etc. The noise and loss of this structure are relatively large when the capacity is 5000kvar to 12000kvar. [0003] Therefore, how to reduce the noise and loss of the reactor has become an urgent technical problem to be solved by those skilled in the art. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the...
