Abstract
The utility model relates to a double triple-column iron core magnetically controlled reactor with a horizontal yoke. The iron core structure thereof is that a main iron core adopts paratactic double triple-column iron cores which are connected with six horizontal yoke iron cores (three at upper side and three at lower side). The stem of the main iron core is provided with one or a plurality of small sections. Because of the special iron core structure, silicon controlled connected with a double triple-column iron core coil is respectively triggered and conducted in one power frequency period of power voltage and consequently provides a circulation loop for controlling magnetic flow by the horizontal joke. The small section of the working stem has magnetic saturation. The DC control current and the corresponding iron core magnetic saturation can be changed by adjusting the conduction angle of the silicon controlled; consequently, the capability of the reactor can be adjusted continuously. The utility model can directly adjust the reactor smoothly and continuously without increasing extra DC power supply. The utility model has the advantages of simple structure, convenient operation and good safety and credibility.
Description
Technical field
The utility model relates to power equipment in a kind of electrical network, relates to a kind of magnet controlled reactor of electric power system specifically.
Background technology
Reactor is the electric equipment commonly used that carries out reactive power compensation in the operation of power networks.At present mostly to be capacity non-adjustable for the reactor that uses, can not be along with the idle variation of system the change capacity.And magnet controlled reactor can smoothly be regulated the reactor capacity continuously by control thyristor operating angle size, to reach best compensation effect.Usually magnet controlled reactor need use external dc power supply to control the reactor pondage by controllable silicon, makes its magnet controlled reactor structure complicated, and safety and reliability reduce.
Summary of the invention
The utility model proposes a kind of self coupling DC excitation at the defective that existing reactor exists, the magnet controlled reactor that adjusted is convenient, simple in structure.
The concrete technical scheme that addresses the above problem is: a kind of two three-limb core magnet controlled reactors that have horizontal yoke, it is characterized in that: iron core adopts two three-limb cores arranged side by side, be shaped on small bore on the main iron core stem stem, be connected with each three horizontal yoke core up and down, be equipped with insulation board between horizontal yoke core and the main iron core, be with two windings up and down on each stem stem of main iron core, two winding interconnections arranged side by side, the centre tap of winding connects the controllable silicon trigger board, and trigger board links with controller through the photoelectricity isolation.
The utility model has the advantages that: because this unique core structure, the controllable silicon that connects on feasible two three-limb core coils difference triggering and conducting in a power frequency period of supply voltage, thereby for the control magnetic flux provides flow cycle, make the magnetic saturation of work stem stem by horizontal yoke.By regulating thyristor operating angle, can change the size and the corresponding iron core magnetic saturation of DC control electric current, thereby make that the capacity of reactor can be adjustable continuously.This structure just can directly be regulated reactor without external dc power supply, and is simple in structure, easy to operate, safe and reliable.

Among the figure: 1 main iron core, yoke core on 2,3 lower yoke cores, 4 horizontal yoke cores.
Embodiment
Accompanying drawings structure of the present utility model: a kind of two three-limb core magnet controlled reactors that have horizontal yoke, its core structure is the two three-limb core structures of three-phase, as depicted in figs. 1 and 2, six main iron cores 1 adopt two three-limb cores arranged side by side, be connected with each three horizontal yoke core 4 up and down, separate with insulation board between horizontal yoke core 4 and the main iron core 1.
Be shaped on one or more snippets small bore on main iron core 1 stem stem.Stem stem is with winding outward, and the winding centre tap connects the controllable silicon trigger board in the usual way, and trigger board is through photoelectricity isolation connection controller.The main iron core stem stem is a circular cross-section, and main iron core yoke up and down is rectangle or circular cross-section, and horizontal yoke core 2 is a rectangle.
The sheet shape of main iron core 1, last yoke core 2, lower yoke core 3, horizontal yoke core 4 has nothing in common with each other, folded separately system main iron core 1 and horizontal yoke core 4, each having independent clamping element clamps, main iron core 1 has overlapped coil, make up again after the single device body assembling, and separate with insulation board between horizontal yoke core 4 and the main iron core 1, do not form short circuit, before and after device body main iron core 1 ground connection that connects together, each horizontal yoke core 4 carries out ground connection separately.
