High-voltage orthogonal magnetized single-phase controllable reactor

Abstract

The invention relates to a high-voltage orthogonal magnetized single-phase controllable reactor which comprises a working iron core, a working winding (2), control iron cores (5, 7) and control windings (6, 8), wherein the working iron core is formed by a main iron core column (1), a first side yoke (11), a second side yoke (12), a first side column (3) and a second side column (4). The main ironcore column (1) is a single column with a constant cross section and is formed by superposing a plurality of iron core cakes with gaps; the first side column (3) and the second side column (4) are ofconstant-cross-section iron cores without air gaps and are arranged in a bilateral symmetry manner with respect to the main iron core column (1); the first side yoke (11) and the second side yoke (12) are of constant-cross-section iron cores without air gaps and are arranged in an up and down symmetry manner with respect to the main iron core column (1); the working winding (2) is sheathed on themain iron core column (1); the two control iron cores (5, 7) are orthogonal to the main iron core column (1); and the control windings (6, 8) are respectively sheathed on control side columns of the control iron cores (5, 7).

Description

technical field [0001] The invention relates to a reactor used in a power system, in particular to a controllable reactor based on the principle of orthogonal magnetization. Background technique [0002] At present, the controllable reactor with adjustable magnetic bias can be divided into two types from the structure of the core: the magnetic valve type and the core column saturation type controllable reactor. Among them, the magnetic valve type controllable reactor, such as Chinese patent 95223137.9, etc.; the core column saturated type controllable reactor, such as Chinese patent: 99250344.2, etc. The magnetic valve type controllable reactor is to change the reactance of the winding by controlling the magnetic saturation state of the small section section provided on the main iron core column, so as to achieve the purpose of changing the reactance value of the reactor. Its structural characteristics are: the iron core has two The main iron core column and the correspondi...
