Abstract

The utility model relates to a magnetically controlled reactor with double bevelled triangular right-angled elliptic three-column iron cores. Double triangular three-column iron cores are adopted and are arranged side by side, a central column of the main iron core is connected with an upper yoke and a lower yoke into a whole, and an insulating board is placed between the iron core of a horizontal yoke and the main iron core. Two ends of iron core sheets of the upper yoke and the lower yoke are folded into obtuse angles to be spliced on three columns of each iron core to form a structure with a linear end part and a triangular middle part. Lapped seams between the central column of the main iron core and the iron core of the upper yoke and between the central column of the main iron core and the iron core of the lower yoke are straight lapped seams, and the central column of the main iron core has a multistage stepped section which is elliptic. Due to the adoption of the unique iron core structure, a silicon controlled rectifier connected to a coil of the magnetically controlled reactor with the double bevelled triangular right-angled elliptic three-column iron cores is respectively triggered and conducted within one period of a power voltage, so that a circulation loop for controlling a magnetic flux is provided through the upper yoke and the lower yoke and the central column of the working main iron core is magnetically saturated. Through adjusting the conduction angle of the silicon controlled rectifier, the direct current control current and the magnetic saturation of the corresponding iron core can be changed, so that the capacity of the reactor can be continuously adjusted. By using the structure, the reactor can be directly adjusted without a direct current power source, and is convenient to operate, simple in equipment and relatively remarkable in economic benefit.

Description

The oval magnet controlled reactor unshakable in one's determination in the two three post triangle right angles of fold angle type

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 oval magnet controlled reactor unshakable in one's determination in the two three post triangle right angles of a kind of fold angle type; It is characterized in that: the unshakable in one's determination arrangement of two three post triangles of employing unshakable in one's determination; 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.Iron yoke lamination two ends are folded into the obtuse angle up and down, are plugged on three core limbs, and forming an end is structure triangular in shape in the middle of the straight line.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 an ellipse.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; Make the controllable silicon that connects on the coil of the oval magnet controlled reactor unshakable in one's determination in the two three post triangle right angles of fold angle type triggering and conducting respectively in the one-period of supply voltage; 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 oval magnet controlled reactor unshakable in one's determination in the two three post triangle right angles of a kind of fold angle type, its iron core of electric reactor structure is the two three post triangular structures of three-phase, and is as shown in Figure 1.Main core 1 adopts two three post triangle 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.Iron yoke lamination two ends are folded into the obtuse angle up and down, are plugged on three core limbs, and forming an end is structure triangular in shape in the middle of the straight line.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 triangle 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 oval, as shown in Figure 3.The iron yoke heart is an elliptic 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.
