Abstract
The utility model relates to a core type reactor magnetic conducting plate, which belongs to the technical field of reactor manufacturing. The technical scheme includes that the magnetic conducting plate comprises an upper magnetic shielding plate (1) and a lower magnetic shielding plate (2) which are formed by overlaying silicon steel plates, wherein the upper magnetic shielding plate is disposed between an iron core post (3) and an upper iron yoke (4), and the lower magnetic shielding plate is arranged between the iron core post and a lower iron yoke (5). The magnetic conducting plate has the advantages that the magnetic conducting plate actively and effectively leads partial magnetic flux leakage into a main flux via the upper magnetic shielding plate and the lower magnetic shielding plate, thereby achieving the purpose of controlling magnetic flux leakage; the structure requires no copper shielding or magnetic shielding installed on a box wall, thereby saving materials; simultaneously, the magnetic shielding has the advantages of simple manufacturing, convenient installation and the like, and material can be bits and pieces of silicon steel sheets so as to further save cost; and additionally, the magnetic shielding nearly covering a coil is capable of applying pressing force on the upper portion of the upper iron yoke in press mounting of a reactor body, and simultaneously pressing the iron core post and the coil so as to lower noise and vibration of a reactor.
Description
Affiliated technical field:
The utility model relates to a kind of core type reactor magnetic conductive board, belongs to reactor manufacturing technology field.
Background technology:
Electric energy is a kind of cleaning basic energy resource of easy controlled extensive use in worldwide again.In electric power system, reactor is mainly used in the building-out capacitor electric current, weaken capacity effect, the restriction system power-frequency voltage raises, and can effectively suppress switching overvoltage, can also play the self-excitation phenomenon that produces when eliminating the unloaded long line of synchronous generator band, thereby the reliability service of assurance circuit is one of most important power equipment.Reactor mainly is divided into two big classes, and the one,, be not called air core reactor with reactor unshakable in one's determination, the 2nd, the reactor that band is unshakable in one's determination is called core type reactor.Core type reactor mainly is made up of unshakable in one's determination and coil two parts.
For core type reactor, when passing to alternating current in the coil of iron-core reactor, it just produces two parts magnetic flux, and a part is a main flux, and it is along iron circuit (air gap, iron yoke etc. between cake unshakable in one's determination, cake) closure, with whole wire turn intersecting chains; Another part is a leakage flux, and it is mainly along the closures such as magnetic screen on air, oil, fuel tank tank wall or the tank wall.The reactance of reactor is the principal reactance of main flux generation and the leakage reactance sum that leakage flux produces.Reactor leakage magnetic flux is excessive, reduced the linearity of reactor, reduced the efficient of reactor, and leakage flux enters hardware generation eddy current, increase the loss of reactor,, the possibility that produces local overheating is just arranged if leakage flux is too concentrated, even the cracking transformer oil, cause whole reactor to work.Leakage field how to control reactor is the key point that reactor manufactures and designs.At present, for reduce the reactor leakage field influence, method commonly used has: 1, permeability magnetic materials such as silicon steel sheet are installed on the fuel tank tank wall, are reduced the eddy current loss that leakage flux produces.2, diamagnetic material such as copper coin is installed on the fuel tank tank wall, is prevented that leakage field from entering tank wall.Though first method has reduced the loss that leakage field produces, in fact do not reduce the leakage flux of reactor; Though the second method copper shield has resisted leakage field, can't guarantee that the leakage field of keeping out enters into main flux, also leakage field might be imported other structural member, have uncontrollability.These two kinds of methods all have defective separately, all belong to the category of passive defense.
The utility model content:
The utility model purpose provides a kind of core type reactor magnetic conductive board, initiatively effectively the part leakage field is introduced main flux, has reached the purpose of control leakage field, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
The core type reactor magnetic conductive board comprises last magnetic shield panel and the following magnetic shield panel with silicon steel sheet stack one-tenth, and last magnetic shield panel is arranged between core limb and the upper yoke, and following magnetic shield panel is arranged between core limb and the lower yoke.
Last magnetic shield panel is the same with following magnetic shield panel shape, is rectangle or square, and area coverage can be close according to magnetic in calculating adjustment size control leakage field and the magnetic screen, to guarantee shield effectiveness.
Last magnetic shield panel and following magnetic shield panel play shielding, guide magnetic flux, and the stack direction of its silicon steel sheet is perpendicular to the axle center of reactor, and the grain orientation direction of silicon steel sheet is also perpendicular to the axle center of reactor.
Between upper and lower magnetic shield panel and the core limb air gap is arranged, and between the upper and lower iron yoke insulation board is arranged, both guaranteed the diffraction of magnetic circuit, prevent that again magnetic flux from forming circulation between magnetic screen and iron yoke.
The beneficial effects of the utility model: by upper and lower magnetic shield panel, initiatively effectively the part leakage field is introduced main flux, reached the purpose of control leakage field; This structure need not installed copper shield or magnetic screen on tank wall, saved material; Simultaneously, this magnetic screen has makes characteristics such as simple, easy for installation, and material can be chosen the silicon steel sheet tailing, has saved cost again; In addition, because this magnetic screen almost can cover coil, apply thrust on upper yoke top when reactor device body press-fits, magnetic shield panel can play the effect of while compacted iron stem and coil, has reduced the noise and the vibration of reactor.
