Abstract
The utility model relates to a cylindrical iron-core reactor without yoke, comprising an iron core made from ferromagnetic materials in an integral form, and a reactor winding composed of a plurality of encapsulating layers and equipped around the iron core. The iron core is a cylinder, composed of an inner and an outer insulation cylinders and silicon steel sheets therebetween; air duct insulation battens are equipped between each encapsulating layer of the reactor to form heat-dissipating airways. Because the cylindrical iron core, formed by the silicon steel sheets arrayed in a radial pattern and the inner and outer insulation cylinders rolled, is added into the inner cavity of traditional hollow reactors, the magnetoconductivity of the magnetic circuit of the reactor and the usage rate of the iron core are improved, and thereby the volume of the reactor and the additional losses are greatly reduced. The utility model is simple in structure, low in cost and suitable for products of various capacities.
Description
The utility model relates to the iron-free yoke cylindrical shape iron core reactor that a kind of electric power system is used.
Existing reactor kind is more, structure is different.As a kind of dry-type iron-core reactor, its main flux stacks the magnetic core and the last lower yoke closure of common composition through the magnetic cake alternatively layered of the gap-gas segregating ring of non-magnet material and permeability magnetic material, and lower yoke need consume more ferromagnetic material on it, and product cost is higher relatively.Another kind of half core dry reactor, its magnetic circuit is made up of cylindricality magnetic core and extraneous air, is identical with the non-iron yoke core type reactor of mentioning in the research article of Soviet Union's power industry monograph in 1974.Because its permeability magnetic material utilance is very low, material consumption is more, and product cost is still higher, and loss is bigger, and heat dispersion is relatively poor, and therefore, difficulty is applied to medium above capacity product.Also have a kind of hollow dry-type reactor, owing in its magnetic circuit, do not have permeability magnetic material, thereby volume is bigger.
The purpose of this utility model aim to provide a kind of simple in structure, volume is little, cost is low, loss is little, can be suitable for various capacity products and thermal diffusivity iron-free yoke cylindrical shape iron core reactor preferably, to overcome the deficiencies in the prior art part.
A kind of iron-free yoke cylindrical shape iron core reactor by this purpose design, comprise by the one-time formed iron core of ferromagnetic material, wound core be provided with by the multi-layered enveloped reactor winding of forming, its architectural feature is that described iron core is cylindric, is made up of inside and outside insulating cylinder and silicon steel sheet therebetween; Between each layer of reactor sealed and iron core and innermost layer be provided with the air channel insulating stay between sealing, to constitute the heat radiation air flue.
Described silicon steel sheet is arranged radially around the center of circle of cylindric iron core, and inside and outside insulating cylinder body is wrapped up in and put its appearance.Described reactor upper end is provided with outlet terminal and lifting rod, and the lower end is provided with lower wire end and locating piece.
The utility model is owing to wrap up in the cylindric iron core of putting in traditional air core reactor inner chamber adding by the radial arrangement of silicon steel sheet and by inside and outside insulating cylinder, improved the magnetic conductivity of reactor magnetic circuit, improve the utilance of iron core simultaneously, thereby significantly reduced the volume of reactor; Outlet is simple up and down, and no starframe outlet arm does not have any closed-loop path, has significantly reduced supplementary load loss.Thereby it is simple in structure, cost is low, loss is little, and it is good, non-maintaining to be suitable for various capacity products and thermal diffusivity, all can adopt indoor and outdoor.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is embodiment master's TV structure schematic diagram;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of looking up of Fig. 1;
Fig. 4 is cylindric iron core cross-sectional structure enlarged diagram.
Referring to accompanying drawing, this iron-free yoke cylindrical shape iron core reactor, inner chamber are the one-time formed cylindric iron core 1 of ferromagnetic material, are provided with by four layers around cylindric iron core and seal the 2 reactor windings of forming.The silicon steel sheet 9 of iron core 1 is arranged radially around the center of circle of cylindric iron core, and inside and outside insulating cylinder body 8,7 is wrapped up in and put its appearance.Between each layer of reactor sealed and iron core and innermost layer be provided with uniform air channel insulating stay 3 between sealing, to constitute the heat radiation air flue.The reactor upper end is provided with outlet terminal 4 and lifting rod 6, and the lower end is provided with outlet terminal 4 and locating piece 5, so that its support level and lifting position to be provided.
