Multilevel Orthogonal Magnetic Saturation Controllable Reactor

Abstract

The invention relates to a multilevel orthogonal magnetic saturation-type controlled reactor. A reactor main body structurally consists of an upper yoke, a lower yoke, a magnetic conduction core column, a return yoke and a working winding, wherein the working winding is sleeved on the magnetic conduction core column. The reactor is characterized in that the magnetic conduction core column is formed by alternatively arraying and overlying a plurality of orthogonal magnetic control iron core cakes and uncontrollable iron cores; each orthogonal magnetic control iron core cake consists of a magnetic control iron core and a control winding which is wound on the iron core, exciting current passes by the control windings so as to generate control magnetic flux in the orthogonal magnetic control iron core cakes, and the direction of the control magnetic flux and the direction of the alternating current main flux of the reactor form 90-degree orthogonality; and the uncontrollable iron cores are always in unsaturated states, and the magnetic saturation degree of the orthogonal magnetic control iron core cakes is controlled according to the size of the exiting current. The multilevel orthogonal magnetic saturation-type controlled reactor not only can realize variable smooth regulation, but also responds fast and has small harmonic content.

Description

Technical field [0001] The invention relates to a reactor, which is a multi-stage orthogonal magnetic saturation type controllable reactor used in power transmission, power supply and distribution systems. Background technique [0002] The controllable reactor, as an important irreplaceable equipment in the power system, plays a huge role in compensating capacitive reactive power, limiting overvoltage, improving power quality, and reducing line active power loss. There are many types of controllable reactors. Among them, magnetron reactors based on the principle of DC magnetic saturation control occupy a very important position in controllable reactors. They have the advantages of high reliability, small control capacity, and continuously adjustable reactance values. But there are also problems of slow response speed and large harmonic content.
