Abstract
The utility model relates to a damping ring for a magnetic saturated reactor, which comprises a boxed casing and a winding type annular iron core arranged inside the boxed casing and wound with iron-nickel based alloy strips. A box and a box cover of the boxed casing are respectively provided with a through hole having an inner wall and used for being sleeved on a busbar, the winding type annular iron core is connected with the inner wall of the boxed casing through a silicon rubber fixing layer, and the shape and the size of a hole arranged in the middle of the winding type annular iron core are the same as those of the through hole having the inner wall and arranged on the box cover. The damping ring has the advantages that the winding type annular iron core is wound with the iron-nickel based alloy strips having high magnetic permeability and low vortex, and accordingly the magnetic saturated reactor comprising the damping ring circularly sleeve on the busbar is high in inductance, easy in saturation point adjustment, smaller in volume and easy in installation.
Description
Technical field
The utility model relates to a kind of magnetic saturation reactor damping ring, and the magnetic saturation reactor of forming with this damping ring is used for the electronic circuit be made up of thyristor.
Background technology
In the electronic circuit of forming by thyristor; be the sudden change (di/dt) that is limited in electric current in the main circuit; the protection electronic devices and components; usually use saturable reactor, saturable reactor commonly used has two kinds, and first kind is the damping ring that adopts the Ferrite Material compacting to form around knot; the above-mentioned damping ring of some is enclosed within upward composition saturable reactor of bus row; the quantity of damping ring is calculated according to the characteristic and the load of main circuit, and the shortcoming of this saturable reactor is that inductance value is little, and saturation point is adjusted difficulty.Second kind be on the iron core that builds up with silicon steel sheet around on the saturable reactor made of winding, be characterized in that volume is bigger, noise is also bigger.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly has that inductance value is big, saturation point is easily adjusted, volume is less, easy-to-install magnetic saturation reactor damping ring.
The technical scheme that its technical problem that solves the utility model adopts:
The utility model comprises cassette shell and is positioned at the winding type annular core that is turned to by the iron nickel base alloy band of cassette shell; Be respectively equipped with the through hole that has inwall that is used to be enclosed within on the bus row on the box body of described cassette shell and the lid, described winding type annular core is connected with the inwall of described cassette shell by the silicon rubber fixed bed, the shape of the through hole that has inwall on the hole that is positioned at described winding type annular core middle part and the described lid and big or small identical.
In the utility model, on described lid and box body, be respectively equipped with the equal round boss of height of four symmetries.
The beneficial effects of the utility model are because the winding type annular core that adopts permeability height, iron nickel base alloy band that eddy current is little to turn to, so be enclosed within the inductance value of the last magnetic saturation reactor of forming of bus row with this damping ring big, saturation point is easily adjusted, and volume is less, is easy to install.
