Abstract
The utility model relates to a half-core dry reactor which is provided with a magnetic core 1 integrally made from magnetic conductivity materials once. Reactor coils 2 surrounds the magnetic core; an interval supporting insulating rod 3 is arranged between the magnetic core and the reactor coil; the upper and the lower ends of the integration of the magnetic core and the reactor coil are provided with a star-shaped pressing frame 4. The utility model which has the advantages of simple structure, small size, low loss, good integral performance and no noise problem caused by loose can be used indoors and outdoors.
Description
The utility model belongs to the reactor that electric power system is used.
In the prior art, a kind of reactor with T-shaped core, its magnetic core are to form complete magnetic loop around whole reactor winding, thereby the consumption of materials of magnetic core is big, the cost height; Cause the magnetic core size huge, complicated in mechanical structure, easily loosening when also causing operation to be used, noise is big; Its magnetic core is to be exposed in the air in addition, can not be used for the open air, requires also higher to indoor environment.Another kind of its core of dry-type air-core reactor does not have permeability magnetic material and does fuse, and air is fuse, but air reluctance is big, and permeability is low, thereby core section is long-pending big, and overall volume is big, and loss is also just big.
The purpose of this utility model provides a kind of semi-core type dry reactor, make its permeability height, simple in structure, volume is little, loss is low, overall performance is good, noiselessness, indoor outer all can use.
This purpose realizes with following technical proposal: this semi-core type dry reactor, it has by the one-time formed magnetic core of permeability magnetic material, wounded core and is provided with reactor winding, between magnetic core and reactor winding, be provided with and support insulating rod at interval, and be provided with star pressure frame at the upper and lower end of their formation one.
The utility model is because its magnetic core one-time cast-forming is an one, thereby good integrity, and simple in structure, the non-loosening noise problem all can adopt indoor and outdoor.Core section is little in addition, and whole reactor volume is dwindled significantly, and simultaneously because smaller volume, coil also dwindles, thus the length of every wire turn will reduce, that is to say reactor main loss---coil loss is reduced largely.
Provide an embodiment below in conjunction with accompanying drawing:
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
As shown in Figure 1, 2: this semi-core type dry reactor, have by silicon steel sheet and build up cylinder shape magnetic core 1, again it is solidified into integral body with poured with epoxy resin; Then flat excellent 3 of pulling moulding is arranged around magnetic core, be fastened, make it as support (being beneficial to heat radiation) at interval with the impregnation glass fiber; Reactor winding 2 usefulness impregnation glass fiber will be sealed formation inside and outside the wire turn; Star is pressed frame 4 and reactor winding 2 up and down at last, and magnetic core 1 usefulness impregnation glass fiber colligation is tightened to one.Advance baking oven then after 130 ℃～150 ℃ curing, promptly make the unified integral body of sound construction, spray antiultraviolet lacquer again.
