Double-three-column oblique angle round iron core magnetically controlled reactor

Abstract

Provided is a double-three-column oblique angle round iron core magnetically controlled reactor. According to the double-three-column oblique angle round iron core magnetically controlled reactor, an iron core comprises two three-column iron cores which are arranged in an abreast mode, a main iron core column is connected with an upper iron yoke and a lower iron yoke into a whole, and an insulating plate is placed between a horizontal yoke iron core and a main iron core. A joint between a main iron core column and an upper iron yoke iron core and a joint between the main iron core column and a lower iron yoke iron core are inclined joints. The main iron core column is a stair-shaped multi-step section which is oval. Due to the unique iron core structure, controllable silicon connected on a coil of the double-three-column oblique angle round iron core magnetically controlled reactor is enabled to be respectively activated to be conductive in a period of a power supply voltage, control for magnetic flux is provided with a circulating return circuit through the upper iron yoke and the lower iron yoke, and a working main iron core column is enabled to be in magnetic saturation. The magnitude of a direct current control current and a corresponding iron core magnetic saturation degree can be changed through adjustment of a controllable silicon conductive angle, and therefore capacity of the double-three-column triangular right-angle oval iron core magnetically controlled reactor is capable of being continuously adjustable. Due to the fact that the reactor can be directly adjusted without a provision of a direct current power source, the double-three-column triangular right-angle oval iron core magnetically controlled reactor is convenient to operate, simplified in equipment, and remarkable in economic benefit.

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...
