Switching reactor with novel coil structure

Abstract

The invention belongs to the technical field of manufacturing of transformer products, and particularly relates to a switching reactor with a novel coil structure. The switching reactor comprises a double-arm coil, an iron core part and an iron core clamping part, wherein the iron core part is of a three-phase three-column structure, and the core column of each phase is sleeved with the double-armcoil; the double-arm coil comprises a first arm coil body and a second arm coil body, and the first arm coil body and the second arm coil body are oppositely wound on the core column to form a firstarm inner layer coil body and a second arm inner layer coil body respectively; the first arm coil and the second arm coil are crossed and transposed in the middle of the core column in the height direction to rise to the outer layer to be wound to form a first arm outer-layer coil and a second arm outer-layer coil. By adopting a crossed coil distribution structure, the two arm coils of the switching reactor are completely symmetrical in structural space and magnetic field space positions, and the distance between the two arm coils is reduced as much as possible on the premise that the two armcoils meet the insulation requirement, so that the magnetic coupling performance of the two arm coils is improved, and the performance requirements of the switching reactor in a non-bridging state anda bridging state are met.

Description

technical field [0001] The invention belongs to the technical field of manufacturing transformer products, in particular to a switching reactor with a novel coil structure. Background technique [0002] Switched reactor is a device used in reactive switching voltage regulation. Usually, the two-arm coils of switched reactors adopt a double U-shaped structure or an axial arrangement structure. This type of coil type operates in a non-bridge state However, due to the poor magnetic coupling of the coils of this type of switching reactor, the switching reactor cannot achieve the effect of minimizing the voltage division of the two-arm coils in the bridging state, making the voltage regulation There is a big difference in precision performance. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a switched reactor with a new coil structure to solve the problem that the voltage deviation of the corresponding tap p...
