Abstract
The invention discloses a novel structural electric reactor iron core, and belongs to general parts of a transformer or an inductor, wherein the iron core is especially applied to dry-type series electric reactors and oil-immersed series electric reactors. The novel structural electric reactor iron core comprises core columns, cross yokes and longitudinal yokes, and is characterized in that two structures shaped like a Chinese character 'ri' are respectively composed of the three core columns and the cross yokes and are arranged in a front and back mode, the longitudinal yokes connect the two structures shaped like the Chinese character 'ri' at the front and the back together through clamping pieces, the two structures are fixed and clamped through the clamping pieces, the height of the longitudinal yokes is the same with that of the cross yokes, the upper end face and the lower end face of each longitudinal yoke are flush with the upper end face and the lower end face of each cross yoke, and the core columns, the cross yokes and the longitudinal yokes are connected mutually for forming a three-phase closed magnetic circuit. According to the novel structural electric reactor iron core, original alternating current and direct current magnetic yokes are optimized and integrated, the height of a device body is effectively reduced, and the use amount of the iron core, transformer oil and an oil tank is reduced. In the manufacturing process, the iron core is integrally solidified after being piled up to reach the thickness, labor hours are saved, operation is flexible, and the integral strength is high. The novel structural electric reactor iron core can be applied to electric equipment such as dry-type electric reactors, oil-immersed electric reactors and arc suppression coils.
Description
Technical field
The invention belongs to the general parts of transformer or inductor, particularly be applied to the iron core of dry type, oil immersed type series reactor.
Background technology
In the power equipments such as dry reactor, oil-immersed electric reactor, when alternating current path and DC channel existed simultaneously, two magnetic fluxs had respectively independently passage, and circulate in passage separately.For building both paths, transverse and longitudinal and vertical yoke are arranged above and below, as shown in Figure 3.This structure has increased the materials'use amount of device height degree with iron core, transformer oil, fuel tank etc., and cost is corresponding increase also.
Summary of the invention
For two magnetic fluxs that overcome existing reactor have respectively the device height that passage independently causes, the deficiency that consumptive material is many, the invention provides a kind of new structure iron core of electric reactor, this new structure iron core of electric reactor only has an iron yoke, the iron yoke is become with vertical yoke piece by horizontal yoke, can consist of simultaneously the path of alternating current-direct current magnetic flux, iron yoke and stem consist of the magnetic circuit of reactor, and that this mode can be applied to is single-phase, three equate multiple magnetic structures.
The technical solution adopted for the present invention to solve the technical problems is: a kind of new structure iron core of electric reactor, comprise stem, horizontal yoke, vertical yoke, it is characterized in that: two day font structure in tandems that formed by three radical center posts and horizontal yoke, vertical yoke by folder with former and later two days font structure be linked together, and use folder to fix and clamp; Wherein, the height of vertical yoke is identical with horizontal yoke, and the upper and lower end face is also concordant with horizontal yoke; Stem, horizontal yoke, vertical yoke three are coupled to each other and form the three-phase closed magnetic circuit.
The cross section of described stem is rectangle, circle or oval.
The manufacture method of this new structure iron core of electric reactor is, stem and horizontal yoke be closed assembly simultaneously, and two-layer silicon steel sheet discharges successively up and down, mutually connects, the thickness that every stack is certain, and carefully shaping makes it to reach technological requirement and effectively is connected into an integral body.With stand up after the parts such as folder, pull bar connect, and use and without the colligation of latitude band or painting brush lacquer unshakable in one's determination stem solidified as a wholely, reach enough intensity after the oven dry of heating, the impact when resisting the equipment operation.Vertical yoke is according to the size of drawing requirement, and the silicon steel sheet closed assembly is neat, and uses folder to clamp.
The technical thought of this patent is followed electromagnetic induction principle, has improved the correlation of alternating current-direct current magnetic circuit part, and dc circuit magnetic loop is arranged between two stems.During equipment work, induce alternating flux in iron core, behind the rectangular area that process stem, horizontal yoke, vertical yoke three cross, the alternating current-direct current magnetic flux forms path along transverse and longitudinal yoke and stem respectively, thereby erects path separately.
This structure Effective Raise service efficiency and the balanced ratio of magnetic circuit, even in limit saturation condition, also can satisfy instructions for use, in addition, this structure is the corresponding core loss that reduced also.
This structure is the draw bail that product improvement by repeatedly and test etc. are developed, and by with the Distribution of Magnetic Field of calculating two paths under the different magnetic permeabilitys, both is optimized and combined.This structure Effective Raise service efficiency and the balanced ratio of magnetic circuit, even in limit saturation condition, also can satisfy instructions for use; Simultaneously, also effective lowering device height degree reduces the consumption of the materials such as silicon steel sheet, transformer oil and fuel tank, thereby saves cost.Take the reactor of 3000kvar as example, this product total height reduces 280mm, and total weight reduces 820kg.
The invention has the beneficial effects as follows that this patent is that original alternating current-direct current yoke is optimized and combined, effectively lowering device height degree reduces the consumption of iron core, transformer oil and fuel tank, thereby saves cost.Closed assembly unshakable in one's determination reaches integrally curing behind the specific thickness in the making, saves man-hour, flexible operation, and bulk strength is high.This structure can be applied in the power equipments such as dry reactor, oil-immersed electric reactor, arc suppression coil.
