A kind of ER type three-phase reactor
Technical field
The utility model relates to a kind of reactor, relates in particular to a kind of ER type three-phase reactor.
Background technology
Traditional three-phase reactor exists that the length of magnetic path is unequal, sensibility reciprocal is lower, need the problems such as more copper cash while being wound around winding, performance is single larger limitation, and the magnetic core of metal-powder-core is generally not easy to make three-phase integrated reactor, because its magnetic permeability is low, easy three-phase imbalance.
Utility model content
For solving existing problem in above-mentioned prior art, the utility model provides a kind of ER type three-phase reactor.
The utility model adopts following technical scheme to realize: a kind of ER type three-phase reactor, comprise ER type magnetic core and three windings, described ER type magnetic core comprises yoke on the magnetic core that is magnet, left stem magnetic core, newel magnetic core, yoke under right stem magnetic core and magnetic core, yoke on described magnetic core, left stem magnetic core, newel magnetic core, under right stem magnetic core and magnetic core, yoke is metal-powder-core and makes, described left stem magnetic core, newel magnetic core, right stem magnetic core is set in parallel in yoke on described magnetic core, under magnetic core between yoke, described left stem magnetic core, newel magnetic core, the top of right stem magnetic core contacts with yoke on described magnetic core, described left stem magnetic core, newel magnetic core, the bottom of right stem magnetic core contacts with yoke under described magnetic core, described newel magnetic core is cylinder, yoke on described magnetic core, left stem magnetic core, newel magnetic core, under right stem magnetic core and magnetic core, yoke forms closed magnetic circuit, three consistent being wrapped on described newel magnetic core of described winding direction.
As further improvement of the utility model, on described magnetic core, under yoke, magnetic core, yoke parallels, and described left stem magnetic core, newel magnetic core, right stem magnetic core are perpendicular to yoke under yoke, magnetic core on described magnetic core.
As further improvement of the utility model, on described magnetic core, under yoke, magnetic core, yoke such as is at the large cuboid.
As further improvement of the utility model, described left stem magnetic core, right stem magnetic core such as are at the large cuboid.
As further improvement of the utility model, the cross-sectional area of described newel magnetic core is the twice of the cross-sectional area of described left stem magnetic core, right stem magnetic core.
Compared with prior art, the utlity model has following beneficial effect: the utility model adopts and on newel magnetic core, is wound around three windings that direction is consistent, solved the unequal problem of the length of magnetic path, guaranteed the balance of three-phase, meanwhile, the design of the cylinder of newel magnetic core, be more conducive to the raising of sensibility reciprocal, and while being wound around winding, can more economize copper cash, save cost, better meet performance requirement.
