Abstract
The invention discloses a kind of manufacture method of iron powder iron core power reactor.It may further comprise the steps: with the main material of iron powder as the iron core of reactor, add a spot of silicon and aluminium again, the shared percentage by weight of iron sial is respectively 85%, 9% and 6%, adds the epoxy resin of 0.05wt% again, is mixed by blender; Mixed iron powder and epoxy resin are put into mould, at 3T/cm
3Under the pressure condition, be warmed to 110 ℃, be pressed into ring-shaped core, coil again.The iron powder iron core power reactor that adopts the inventive method to produce has reduced the magnetic hysteresis loss and the eddy current loss of iron core, has reduced vibrating noise, and iron core is unsaturated, has favorable linearity, and whole reactor volume is little.
Description
Technical field
The present invention relates to a kind of manufacture method of iron powder iron core power reactor.
Background technology
In the existing power system, use the series and parallel reactor in a large number, mainly be divided into iron core and hollow two big classes.Wherein air core reactor has advantages such as good linearity, mechanical strength height, noise are little, obtained application in the occasion that does not need big inductance value, but it has self intrinsic shortcoming, such as: inductance value is little, is difficult to realize big inductance and big capacity; Bulky, floor space is big, is not easy to centralized management; Do not have closed magnetic loop so that magnetic field to disperse seriously, to around stronger electromagnetic pollution is arranged, and the restriction also be subjected to surrounding environment is installed.Than air core reactor, iron core reactor has obtained extensive use with advantages such as its big inductance value, small size and electromagnetic interference are little in some occasion.But existing iron core reactor certainly will increase the total losses of reactor because the existence of iron core magnetic material has increased magnetic hysteresis loss and eddy current loss; Iron core is easily saturated, makes inductance value change, and has reduced the action effect of reactor, and the also inevitable loss that has further strengthened reactor makes electrical network have destabilizing factor; The mechanical oscillation noise is big, and is particularly particularly outstanding than problem under the serious situation at the system harmonics damage ratio, thereby surrounding environment is caused certain noise pollution, also shortens the useful life of reactor simultaneously.
Summary of the invention
In order to solve the big and easily saturated technical problem of the existing ubiquitous noise of iron core reactor, the present invention proposes a kind of manufacture method of iron powder iron core power reactor.Iron powder iron core power reactor of the present invention has reduced the magnetic hysteresis loss and the eddy current loss of iron core, has reduced vibrating noise, and iron core is unsaturated, has favorable linearity, and whole reactor volume is little.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: with the main material of iron powder as the iron core of reactor, add a spot of silicon and aluminium again, the shared percentage of iron sial is respectively 85%, 9% and 6%, adds the epoxy resin of 0.05wt% again, is mixed by blender; Mixed iron powder and epoxy resin are put into mould, at 3T/cm
3Under the pressure condition, be warmed to 110 ℃, be pressed into ring-shaped core, coil again.
Technique effect of the present invention is: the present invention uses the core material of iron powder as reactor, add the ring iron core reactor that an amount of silicon, aluminium and epoxy resin are made, have following advantage: 1) the magnetic hysteresis coefficient of dilatation of iron core is near zero, thereby the iron core that weakened to mechanical transformation of energy, has also reduced the magnetic hysteresis loss and the eddy current loss of iron core with electromagnetic energy simultaneously; 2) equivalent permeability of iron powder iron core is about 60, and has reduced the volume of reactor, has reduced the floor space of equipment, can realize reactor is put into the control cubicle centralized management; 3) iron core is difficult for saturatedly, has favorable linearity, can guarantee that stablizing of reactance value is constant, makes that its effect is brought into play to greatest extent; Greatly reduce vibration noise simultaneously, alleviated noise pollution, prolong the useful life of reactor.
The present invention is further described below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structure chart of annular core reactor of the present invention.
Embodiment
Annular core reactor as shown in Figure 1, wherein annular core 1 is made up of three kinds of elements of iron sial and epoxy resin mixing, and the shared percentage of each element of iron sial is respectively 85%, 9% and 6%, adds the epoxy resin of 0.05wt% in iron powder,, mix by blender; Mixed iron powder and epoxy resin are put into mould, at 3T/cm
3Under the pressure condition, be warmed to 110 ℃, be pressed into ring-shaped core, coil 2 again and promptly make the annular core reactor.
