Abstract

The utility model provides a magnetic-control electric reactor with double three-column right-angle circular iron cores. Two three-column iron cores are arranged side by side; main iron core columns are connected with upper and lower iron yokes into a whole; insulation plates are disposed between cross yoke iron cores and the main iron cores; the junctures between the main iron core columns and the upper and lower iron yoke iron cores are straight junctures; and the main iron core columns are in the shape of multi-stage steps and have circular sections. The unique iron core structure enables silicon controller rectifiers connected to coils of the magnetic-control electric reactor with the double three-column right-angle circular iron cores to be triggered and turned on separately in a period of supply voltage, so that a circulation return circuit can be provided by the upper and lower iron yokes for controlling magnetic flow and thus magnetic saturation of the working main iron core columns is realized. Through adjustment of the turn-on angle of the silicon controller rectifiers, the magnitude of direct current control current and the corresponding magnetic saturation of the iron cores can be changed, so that the capacity of the electric reactor can be adjusted continuously. With such a structure, the electric reactor can be adjusted directly without the supply of direct current supply, thereby being characterized by easy operation, simplification of equipment and relatively significant economical benefit.

Description

The circular magnet controlled reactor unshakable in one's determination in two three post right angles

Technical field

The utility model relates to power equipment in a kind of electrical network, is specifically related to a kind of reactor.

Background technology

Reactor is the electric equipment commonly used that carries out reactive power compensation in the operation of power networks.Mostly the reactor that uses at present is that capacity is non-adjustable, 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 through the size of control thyristor operating angle, 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.

The utility model content

The utility model proposes a kind of self coupling DC excitation to the defective that existing reactor exists, the magnet controlled reactor that adjusted is convenient, simple in structure.

Technical scheme

The utility model solves the technical scheme that its technical problem adopted: the circular magnet controlled reactor unshakable in one's determination in a kind of two three post right angles; It is characterized in that: two three post iron cores of employing unshakable in one's determination are arranged side by side; Main core stem and last lower yoke link into an integrated entity, and are placed with insulation board between the horizontal yoke heart and the main core.Main core stem and iron yoke heart seam up and down be direct seam, and the main core stem is stepped multistage cross section, and the cross section is a circle.Be with two windings on each stem of main core, two winding interconnections arranged side by side, the centre tap of winding connects the controllable silicon trigger board, and trigger board is isolated through photoelectricity and is connected with controller.

The beneficial effect of the utility model

Because this unique core construction; The controllable silicon difference triggering and conducting in the one-period of supply voltage that connects on the coil of the circular magnet controlled reactor unshakable in one's determination in feasible two three post right angles; Thereby for the control magnetic flux provides flow cycle, make the magnetic saturation of work main core post through last lower yoke.Through regulating thyristor operating angle, can change the size and the corresponding magnetic saturation unshakable in one's determination of DC control electric current, thereby make that the capacity of reactor can be adjustable continuously.This structure need not provide DC power supply just can directly regulate reactor, and is easy to operate, and equipment is oversimplified, and economic benefit is more remarkable.

Embodiment

The structure of accompanying drawings the utility model: the circular magnet controlled reactor unshakable in one's determination in a kind of two three post right angles, its iron core of electric reactor structure is two three rod structures of three-phase, and is as shown in Figure 1.Main core 1 adopts two three post iron cores to be arranged side by side, and links into an integrated entity with each three horizontal yoke heart 4 up and down, is placed with insulation board between the horizontal yoke heart 4 and the main core 1.Main core 1 is directly to stitch with upper yoke unshakable in one's determination 2 and lower yoke 3 seams unshakable in one's determination.Six coils of reactor are enclosed within respectively on six main core stems, press usual manner and connect controllable silicon and diode through outside lead, constitute control circuit.

Pair three post iron cores that adopt unshakable in one's determination are arranged side by side, and the main core stem is multistage stepped, and the cross section is circular, as shown in Figure 3.The iron yoke heart is a circular cross-section up and down.The cross section of the horizontal yoke heart 4 is a rectangle.The cross section of last lower yoke is bigger than the cross section of stem unshakable in one's determination, satisfies the normal magnetic circuit that exchanges on the one hand, satisfies the DC loop of control on the other hand, and the iron yoke heart is unsaturated up and down so that make.

The sheet shape of main core 1, upper yoke iron core 2, lower yoke iron core 3, the horizontal yoke heart 4 has nothing in common with each other.Add the folded separately main core 1 and the horizontal yoke heart 4 made in man-hour.Main core 1 has overlapped and has made up after coil has assembled again, and separates with insulation board between the horizontal yoke heart 4 and the main core 1, does not form short circuit.Two main cores 1 ground connection that connects together, each 4 independent grounding of three horizontal yoke hearts up and down.
