Abstract
The utility model relates to a non-iron yoke core type reactor, which is used on a power system. The utility model comprises an insulating cylinder which is arranged around a magnetic core, a winding of the reactor, an upper wire outlet press frame and a lower wire outlet press frame. The winding is arranged around the insulating cylinder. The magnetic core is formed by that a partition board of non-magnetic conduct materials and a magnetic cake of magnetic conduct materials are alternatively and hierarchically overlapped. The magnetic core is combined with the insulating cylinder to form integration. An iron yoke is not arranged on a main magnetic circuit structure of the utility model and the partition board of non-magnetic conduct materials and the iron cake of magnetic conduct materials are alternatively and hierarchically overlapped to form the magnetic core, so the utility model has the advantages of simple structure, low cost, low loss and better radiating performance, the utility model is suitable for various capacity products and the utility model can be used in doors and out of door.
Description
The utility model relates to the non-iron yoke core type reactor that a kind of electric power system is used.
The title beginning of non-iron yoke core type reactor sees in the research article of Soviet Union electrician industry monograph in 1974, and this field is being developed always.At present, a kind of dry-type iron-core reactor is arranged, its main flux stacks the magnetic core and the last lower yoke closure of common composition through the magnetic cake alternatively layered of the dividing plate of non-magnet material and permeability magnetic material, and last lower yoke need consume more permeability magnetic material, and product cost is higher relatively.Another kind of half core dry reactor, its magnetic core is made by permeability magnetic material fully.Cut off magnetic core owing to lack the dividing plate of non-magnet material, eddy current loss is bigger in the magnetic core, and total losses are also bigger.Because of eddy current loss will cause local overheating in magnetic core, so this kind structure difficulty is applied on the medium above capacity product, reason is that the magnetic core size of medium above capacity product is bigger, and it is more difficult to dispel the heat, and can aggravate local overheating, thereby jeopardize product normal useful life.
The purpose of this utility model aims to provide a kind of simple in structure, low-cost, low-loss, can be suitable for various capacity products and the non-iron yoke core type reactor preferably that dispels the heat, to overcome the deficiencies in the prior art part.
Press the non-iron yoke core type reactor of a kind of electric power system use of this purpose design, comprise the insulating cylinder body that wounded core is provided with, around the reactor winding of insulating cylinder body setting with go out the line pressure frame up and down, to be described magnetic core stack into column by the dividing plate of non-magnet material with the magnetic cake alternatively layered of permeability magnetic material to its architectural feature constitutes, and magnetic core and insulating cylinder body form a whole.
Described magnetic cake cross section is polygon or circle.Polygonal corresponding sides are zigzag.Dividing plate is circular or corresponding with the shape of magnetic cake.Be evenly equipped with heat dissipation channel between described insulating cylinder body and the reactor winding.
The utility model is not owing to have the iron yoke on the main magnetic circuit structure, have only the magnetic cake alternatively layered of the dividing plate of non-magnet material and permeability magnetic material to stack the magnetic core of common composition, thereby simple in structure, cost is low, loss is low, non-maintaining, can be suitable for various capacity products and heat radiation better, 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 a magnetic cake cross sectional representation;
Fig. 4 is the partition shape schematic diagram;
Fig. 5 stacks main TV structure schematic diagram for dividing plate and magnetic cake alternatively layered;
Fig. 6 is the plan structure schematic diagram that magnetic core combines with insulating cylinder body.
Referring to accompanying drawing, the magnetic cake 5 that permeability magnetic material is made is similar octagon, and corresponding four edges is a zigzag.The dividing plate 6 that non-magnet material is made is for circular, and its external diameter and magnetic cake profile are approaching.Magnetic cake 5 with after dividing plate 6 alternatively layereds stack into column magnetic core 1, is formed a whole with insulating cylinder body 7.Reactor winding 2 and magnetic core arranged concentric, uniform concentric annular heat radiation air flue 3 is provided with out line pressure frame 4 in two ends up and down at reactor between insulating cylinder body and reactor winding.
Described dividing plate is that marble or glass fiber reinforced plastics composite material are made.
