Double three-column rectangular circular iron core magnetically controlled reactor

Abstract

Provided is a double three-column rectangular circular iron core magnetically controlled reactor. Two three-column iron cores are adopted to be arranged side by side, a main iron core column is integrally connected with an up-down iron yoke, 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-down iron yoke iron core is a straight juncture, the main iron core column is in a stair-shaped multistage section, and the section is circular. Due to the unique iron core structure, silicon controlled rectifiers connected to a coil of the double three-column rectangular circular iron core magnetically controlled reactor are respectively triggered and communicated in a conductive mode in a cycle of supply voltage, and thus an up-down iron yoke provides a circulating loop to control magnetic flow, and a work main magnetic iron core column is saturated. Through the adjustment of conduction angles of the silicon controlled rectifiers, the size of direct current control currents and corresponding iron core magnetic saturation degree can be changed, and thus capacity of the reactor is difficult to be continuously adjustable. By means of the structure, the reactor can be directly adjusted without providing of a direct current power supply, 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 through 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 D...
