Magnetic controllable reactor with single-phase double-column oblique-angle circular iron cores

Abstract

A magnetic controllable reactor with single-phase double-column oblique-angle circular iron cores is characterized in that the iron cores are single-phase iron cores, and each iron core has two core columns. Each reactor is composed of three groups of single-phase double-column iron cores. The core columns of a main iron core are connected with an upper iron yoke and a lower iron yoke to form a whole. Seams between the core columns of the main iron core and an upper iron yoke iron core and seams between the core columns of the main iron core and a lower iron yoke iron core are oblique. The core columns of the main iron core are stair-shaped multistage sections which are circular. Due to the unique iron core structures, controllable silicon connected with coils of the magnetic controllable reactor is respectively triggered and powered up in a cycle of power supply voltage, magnitude of direct-current control currents and corresponding iron core magnetic saturation can be changed, and accordingly capacity of the reactor can be continuous and adjustable. According to the structure, a direct-current power supply is needless to be provided, the reactor can be directly adjusted, operation is convenient, equipment is simplified, and economic 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...
