Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment, the patent of the present invention is described in further detail:

[0011] figure 1 It is a schematic diagram of the invented working iron core structure. like figure 1 As shown, the main core column 1 , the first side column 3 , the second side column 4 , the first side yoke 11 , and the second side yoke 12 together form a working iron core with a "day"-shaped structure lying down. The main core column 1 is a single column with equal cross-section, and is formed by stacking a plurality of core cakes with gaps. The first side column 3 and the second side column 4 are equal-section cores without air gaps, and are arranged symmetrically about the main core column 1; the first side yoke 11 and the second side yoke 12 are equal-section iron cores without air gaps , arranged symmetrically up and down with respect to the main core column 1.

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...
