Double-three-column right-angle oval iron core magnetic control electric reactor

Abstract

Disclosed is a double-three-column right-angle oval iron core magnetic control electric reactor. Two three-column iron cores which are side by side arranged are adopted by iron cores of the double-three-column right-angle oval iron core magnetic control electric reactor, a core column of a main iron core is connected with an upper yoke and a lower yoke into a whole, and an insulating plate is placed between a horizontal yoke iron core and the main iron core. Seams of the main iron core column and the upper yoke and the lower yoke are straight seams, the main iron core column is in a stair-step shape with a multi-stage cross section, and the cross section is in an oval shape. Due to the unique iron core structure, controllable silicon connected with a coil of the double-three-column right-angle oval iron core magnetic control electric reactor is respectively triggered to be in breakovern state in one cycle of supply voltage, a control magnetic flux is provided with a circulation loop through the upper yoke and the lower yoke, and the working main iron core column is enabled to be in a magnetic saturation state. By adjusting a controllable silicon conduction angle, the size of the direct current control current and the magnetic saturation level of the corresponding iron core can be changed, and therefore the capacity of the electric reactor is enabled to be adjusted continuously. According to the double-three-column right-angle oval iron core magnetic control electric reactor, the electric reactor can be directly adjusted without the provision of a direct current power supply, the operation is convenient, the equipment is simplified, and the 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 in use are of non-adjustable capacity, and the capacity cannot be changed with the change of system reactive power. 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. Generally, the magnetron reactor needs to use an external DC power supply to control the capacity of the reactor by the thyristor, which complicates the structure of the magnetron reactor and reduces the safety and reliability of use. Summary of the invention [0003] Aiming at the defects of the existing reactor, the present invention proposes a magnetron reactor with auto-coupling direct current excitation, convenient operatio...
