Single-phase double-column oblique angle oval iron core magnetically controlled reactor

Abstract

A single-phase double-column oblique angle oval iron core magnetically controlled reactor is characterized in that iron cores utilizes single-phase iron cores, each iron core comprises two core columns, each reactor is composed of three groups of single-phase double-column iron cores, the main iron core column is connected with an upper-lower iron yoke into a whole, the joint of the main iron core column ad the upper-lower iron yoke is an inclined joint, and the main iron core column is ladder-shaped multi-level section which is oval. By means of the special iron core structure, controllable silicon connected with a coil of the single-phase double-column oblique angle oval iron core magnetically controlled reactor is respectively triggered and communicated in a period of power voltage, and therefore a circulate loop is provided for controlling magnetic flow to enable the work main iron core column to be saturated. By regulation of a controllable silicon communication angle, volume and corresponding iron core magnetic saturation of current can be controlled by changing direct current, and therefore the volume of the reactor can be regulated continuously. The reactor can be directly regulated without a direct current power supply, operation is convenient, equipment is simplified, and economical benefits are obvious.

Description

technical field [0001] The invention relates to a power equipment in a power grid, in particular to a reactor. Background technique [0002] Reactor is a common electrical equipment for reactive power compensation in grid operation. Most of the reactors currently used are non-adjustable in capacity, and the capacity cannot be changed with the change of reactive power of the system. The magnetron reactor can smoothly and continuously adjust the capacity of the reactor by controlling the conduction angle of the thyristor to achieve the best compensation effect. Usually, the magnetic control reactor needs to use an external DC power supply to control the adjustment capacity of the reactor by the thyristor, which complicates the structure of the magnetic control reactor and reduces the safety and reliability of use. Contents of the invention [0003] Aiming at the defects of existing reactors, the invention proposes a magnetically controlled reactor with self-coupling DC exc...
