Abstract
The invention discloses a controllable reactor with orthogonal magnetic rings. Each iron core column, side column or iron yoke is formed by alternatively laminating a plurality of magnetic ring modules and a plurality of cushion blocks which have the same or different shapes and sizes. Each magnetic ring module consists of iron magnetic materials and orthogonal control windings which are wound on the iron magnetic materials. The orthogonal control windings and the cushion blocks are arranged on a plane of the magnetic ring module alternatively. The inner and outer circles of the cushion blocks are arranged along the radial direction of the plane of the magnetic ring module, or one or more circles of the cushion blocks are arranged along the radial direction of the plane of the magnetic ring module. When the orthogonal control windings work in an alternating current supply way, the winding directions of adjacent windings are opposite; and when the orthogonal control windings work in a direct current supply way, the winding directions of adjacent windings are the same or opposite. By changing current of the control windings and a magnetic field, which is produced by the orthogonal control windings and is vertical to main flux, in the magnetic ring modules, the magnetic conductivity of the iron cores of the magnetic rings is changed, so reactance values of alternating current work windings are changed.
Description
Technical field
The present invention relates to a kind of reactor, the controlled reactor of the quadrature magnetic bias type that uses in particularly a kind of electric power system.
Background technology
Controlled reactor can be divided into two types usually, and one type is based on magnetically saturated controlled reactor, and it divides into two kinds of forms from core construction: i.e. magnetic valve type and stem saturation type controlled reactor.Chinese patent 95223137.9 proposes a kind of magnetic valve type controllable reactor, and the magnetic saturation state of the small bore section that is provided with through control main core post changes the reactance of winding, to reach the purpose of the reactance value that changes reactor.Its architectural feature is: iron core has two main core posts and corresponding iron yoke piece to become, and is equipped with a small bore section on two main core posts; Respectively be with one on each core limb and be divided into up and down two-part winding, the number of turn that is connected between the winding tap at controllable silicon two ends is 5% of every post winding total number of turns, and the winding of wherein working belongs to a winding with the control winding.The control winding has the effect of extracting the required magnetization energy of D.C. magnetic biasing concurrently.Its weak point is, owing to be equipped with the small bore section on two main core posts, so its complex structure, manufacturability is poor, cost is high.The stem magnetic saturation type controlled reactor that Chinese patent 99250344.2 proposes has similar structures, it is characterized in that core limb is a uiform section, and its sectional area is less than iron yoke sectional area; Be with the winding of independently working in the control winding outside, this structure is applicable to the voltage levels electric power system.This type reactor is because rated operation point is set in the inelastic region, and the magnetization voltage and current is non-linear, thereby produces very important harmonic wave.In addition, also be prone to produce high induced electromotive force in the control winding of such reactor.Another kind of is novel controlled reactor based on cross magnetization, and the non-contact controllable reactor that Chinese patent 200510130709.4 proposes is a kind of, the use air core coil reactor of this reactor, and reactance value is less, and capacity is less.
