Return yoke folding screen supporting structure for electric reactor

Abstract

The invention relates to the technical field of electric reactors, and particularly relates to a return yoke folding screen supporting structure for an electric reactor. The supporting structure structurally comprises a return yoke, a return yoke pulling plate and a return yoke folding screen, supports are arranged at the corners of the return yoke and between the return yoke and the return yoke folding screen, each support comprises a supporting arm and an arc arm, one end of each supporting arm is fixed on the return yoke pulling plate, and the other end of each supporting arm is fixedly connected with the arc arm. According to the supporting structure, the manufacturing process is simple and easy to implement, the shape of an electrode in oil is rounded, oil gaps are distributed evenly, the field strength of the oil at the corner of the return yoke folding screen is reduced, and the insulation margin is increased.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a reactor side yoke surrounding screen support structure. Background technique [0002] The corner position of the side yoke part of the existing reactor is a right angle, and the side yoke enclosure screen is not only difficult to surround at the corner due to the small bending arc, but also easily damages the ground screen. The electrode shape is relatively sharp, and the oil gap distribution is not uniform. The sharp electrode shape will increase the oil field strength value at the corner, which will inevitably reduce the insulation margin there. Contents of the invention [0003] In order to solve the above problems, the present invention provides a reactor side yoke enclosure supporting structure, which increases the arc at the corner of the side yoke enclosure and improves the insulation margin. [0004] The specific scheme adopted in the present invention is as follow...
