Description
Technical field
The utility model relates to reactor technical field more particularly to a kind of reactors of low noise highly resistance direct current biasing.
Background technique
Amorphous alloy iron core of electric reactor on the market in the prior art, mostly using greatly is c-type iron core, way be winding,
Molding, annealing, dipping lacquer, drying, cutting, grinding, and in cutting, waste of material is generated, loss, excitation will increase,
Powder particle can be generated between amorphous sheet in grinding, loss, excitation can also will increase, and iron core of electric reactor zero load is caused to be damaged
Consumption is big, noise is big；In addition, anti-direct current biasing is bad since c-type iron core is coiling and molding and there are the angles R, overload Decay Rate
It is bad.
And in the prior art, as patent document CN201465728U record a kind of splice type amorphous iron core of reactor, then
Without being wound, cut, grind, loss, the noise of amorphous alloy iron core of electric reactor are reduced, since there is no the angle R, so
Anti- direct current biasing is good, and overload Decay Rate is good.
And in the prior art, it is generally only using the reactor of the splice type amorphous iron core of reactor to bind steel band to it
Iron yoke and stem are bound to tightening state, the technological deficiency that there are appearances is simple and crude, stationary state is bad.
For this purpose, can be by designing the reactor of low noise highly resistance direct current biasing a kind of, to meet the needs of users.
Utility model content
The purpose of this utility model is that providing a kind of low noise highly resistance direct current biasing in order to overcome the deficiencies of the prior art
Reactor.
The reactor of low noise highly resistance direct current biasing, comprising: including stem and be set to the iron of the stem upper and lower ends
Yoke, the stem outside are provided around coil, the coil and the stem insulation set；Folder is provided in the iron yoke at both ends
Part, the folder include the cavity matched with the iron yoke, and the cavity two sides, which are extended, wing plate, the wing plate setting
There is connecting hole；The folder at both ends is connected with fastening bolt by the connecting hole.
Its working principles are as follows:
The folder is socketed on the iron yoke by the way that the cavity is arranged to match, and meets the fixed demand of iron yoke part,
And further by connecting hole in wing plates on two sides to connect fastening bolt, realize the connection between the folder of two sides, and further with
The mode that two sides clamp, meets the whole fixed demand of the splice type iron core of electric reactor.
Further, the stem upper and lower ends are socketed with partition；The coil is set between two endplate, institute
It states partition side and is contacted with the folder, the other side is contacted with the coil.
By the application of the partition, when the folder at both ends is clamped by fastening bolt, the partition at both ends is pressed from both sides
Pressing for part and it is whole press to the coil, to carry out pressing fixation to the coil；The electricity of splice type described in further satisfaction
The whole fixed demand of anti-device iron core.
Further, the coil is compassingly set at the stem periphery in a manner of and is formed with the stem so that copper wire is vertical
Gap is provided with insulating materials between the stem and the coil, vertical around set-up mode by copper wire, meets the reactor
Functional requirement while, so that the reactor is had preferable heat-sinking capability.
Further, the iron yoke is coated with sound-absorbing resin, and the running noise of the reactor is effectively reduced.
Further, amorphous stack of laminations made of the iron yoke and stem are folded by several amorphous thin slices is constituted；Pass through
Using the identical amorphous thin slice of several size specifications being cut out with amorphous band, amorphous bulk lamination made of bonding is folded
Group is used as iron yoke and stem, and after splicing, the vertical copper coil around setting of cooperation is configured, and applies need with meet reactor
It asks.
As being using bulk amorphous alloy iron core of electric reactor made of folding, application need to only shear amorphous alloy strip
Material will not generate damage, unlike c-type iron core needs to cut and grind and c-type iron core be caused to increase loss and noise, and blocky
Amorphous alloy iron core of electric reactor the angle R is not present, so the reactor of the utility model has, loss is low, noise is low, anti-true stream
It biases, the advantageous effects such as the Decay Rate that overloads is good.
Further, air gap plate is provided between the iron yoke and the stem.
The beneficial effect of the utility model compared with prior art is:
1, by the combined application of the folder and partition, meet the whole fixed demand of the splice type iron core of electric reactor.
2, the iron yoke and stem are constituted by amorphous stack of laminations made of folding with amorphous thin slice, meets reactor application
On the basis of, have the beneficial effect that anti-direct current biasing is good, and overload Decay Rate is good and running noise is small.
