Abstract
A magnetically-controlled reactor with double elliptic three-column iron cores with a bevel is disclosed, wherein two three-column iron cores are used and arranged in parallel, the core column of the main iron core is integrally connected with an upper iron yoke and a lower iron yoke, and an insulated plate is placed between a transversal yoke iron core and the main iron core. The seams of the core column of the main iron core and the iron cores of the upper iron yoke and the lower iron yoke are bevel seams, the core column of the main iron core is a stair-shaped multi-step section, and the section is elliptic. Due to the adoption of the unique iron core structure, the switch-on of silicon controlled rectifiers connected to the coil of the magnetically-controlled reactor with double elliptic three-column iron cores with a bevel is triggered during one cycle of a power supply voltage respectively, so that a circulation loop for control on a flux is provided via the upper iron yoke and the lower iron yoke, and the core column of the working main iron core is magnetically saturated. The magnitude of a direct-current control current and the magnetic saturation of the corresponding iron core can be changed by adjusting the conduction angles of the silicon controlled rectifiers, so that the capacity of the reactor is continuously adjustable. Due to the application of the structure, the reactor can be directly adjusted without the provision of a direct-current power supply; and the magnetically-controlled reactor with double elliptic three-column iron cores with a bevel is convenient in operation, simplified in equipment, and remarkable in economic benefit.
Description
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 a kind of two three post oblique 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.The main core stem is a mitre with iron yoke heart seam up and down, and the main core stem is stepped multistage cross section, and the cross section be 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; The controllable silicon difference triggering and conducting in the one-period of supply voltage that connects on the coil of the oval magnet controlled reactor unshakable in one's determination in feasible two three post oblique 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.
Description of drawings:
Below in conjunction with accompanying drawing and execution mode the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is 1 vertical view.
Fig. 3 is the A-A view of Fig. 1.
Embodiment
The structure of accompanying drawings the utility model: the oval magnet controlled reactor unshakable in one's determination in a kind of two three post oblique 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 a mitre 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 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.
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.
