Double three column oblique angle elliptic iron core magnetically controlled reactor

Abstract

Provided is a double three column oblique angle elliptic iron core magnetically controlled reactor. According to an iron core of the reactor, two three column triangle iron cores are arranged side by side, a main iron core column and an up-and-down iron yoke are integrally connected, and an insulating plate is arranged between a transverse yoke iron core and a main iron core. A juncture of the main iron core column and an up-and-down iron yoke iron core is an oblique juncture, the main iron core column is a step-shaped multistage section, and the section is elliptic. Due to a unique iron core structure, silicon controlled rectifiers connected to a coil of the double three column triangle oblique angle elliptic iron core magnetically controlled reactor are respectively triggered and communicated in a conducted mode within a cycle of supply voltage, thus the up-and-down iron yoke provides a circulation loop for controlling magnetic flow, and working main iron core column magnetic saturation is achieved. Through regulation of conduction angles of the silicon controlled rectifiers, the size of direct current control currents and the corresponding iron core magnetic saturation degree can be changed, and thus the capacity of the reactor can be continuously adjusted. A direct current power supply is not needed to be provided, the reactor can be directly adjusted, operation is convenient, equipment is simplified, and economic benefits are remarkable.

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...
