Abstract
The utility model relates to an electric capacitor energy storage type magnetizing machine of a circular iron core, which comprises a control device and a host machine. An iron core adopts an annular core which is composed of a plurality of annular silicon steel sheets in lap winding and is formed by that a whole silicon steel sheet is curled in radial direction and is longitudinally cut opening. The utility model can overcome the defects of the present laminated ring-shaped iron core with gap magnetic leakage, inconsistent magnetic domain arrange, big magneto resistance, etc. The utility model improves magnetizing magnetic circuits and is especially suitable for large magnetic materials with high coercivity to magnetize.
Description
The utility model relates to the device that magnetic material is magnetized, particularly a kind of annular core capacitance energy storage type magnet charger.
Magnet charger mainly is made of two parts, the main frame that iron core and coil constitute; The controller of power supply and corresponding control is provided.But traditional magnet charger more and more can not satisfy the requirement of social development, the making of especially super-huge magnetic material.At first, traditional magnet charger adopts stacked core structure, have the overlapping slit between the silicon steel sheet, so loss is big, efficient is low, easy heating; And the magnetic circuit that silicon steel sheet builds up has the magnetic domain orientation inconsistent (for toroid) of considerable part, causes that magnetic resistance is big, magnetic flux density is not high.Secondly, the controller of traditional magnet charger adopts three-phase alternating current to obtain the high-power power supply, and not only the interference to electrical network is big, and influenced by the destabilizing factor of electrical network, causes magnetize inconsistent.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide on a kind of toroid magnetic domain to arrange and remain unanimity, the magnetic flux density height, magnetic loss is low, the annular core capacitance energy storage type magnet charger that efficient is high.
The technical solution of the utility model is as follows: annular core capacitance energy storage type magnet charger comprises controller and main frame two parts; its middle controller is made up of protective circuit, voltage regulator circuit, energy storage capacitor group, pre exciting switch circuit and control circuit thereof; main frame is made of iron core, magnetize line bag and supporting member; special feature is to have by the bulk silicon steel disc radially to reel, the annular core by multi-disc ring-shaped silicon steel sheet lap wound that forms after the axial cut-outs again.Further, annular core is fixed on the supporting member of approximate " V " shape by adjusting yoke.
Adopt said structure, make to the utlity model has following advantage:
1, reduced silicon steel sheet overlapping slit, magnetic loss is few;
2, the magnetic domain direction unanimity on the iron core has improved magnetic flux density;
3, core volume is less, regulates easy.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is the composition frame chart of the utility model controller;
Fig. 2 is the structural representation of the utility model main frame.
See figures.1.and.2, present embodiment uses 220 volts single-phase alternating current, and input obtains being higher than 450 volts direct current by voltage regulator circuit 2 voltage multiplying rectifiers after protective circuit 1, to 3 chargings of energy storage capacitor group.Charging voltage is adjustable continuously at the 0-450 volt, stops charging when being controlled at preset value by control circuit 5 automatically, and the voltage of energy storage capacitor group 3 is not changed with the variation of supply voltage.The electric energy that capacitor group 3 stores is discharged to the main frame that is connected with lead-out terminal 7 fast by the controllable silicon noncontacting switch of pre exciting switch circuit 4 again, produces pulsed magnetic field magnetic material is magnetized.
Lead-out terminal 7 connects the line bag 9 that magnetizes, and the line bag 9 that magnetizes is wound on the annular core 8, and annular core 8 is radially to be reeled by the bulk silicon steel disc, and what form after the axial cut-outs is formed by multi-disc ring-shaped silicon steel sheet lap wound again.And annular core 8 is fixed on by adjusting yoke 11 on the supporting member 10 of approximate " V " shape, leaves the gap between mandrel lower and the supporting member 10, tightens up or loosens adjusting yoke 11 and can regulate magnetize mouthfuls 12 width and make it parallel of iron core.
With reference to Fig. 2, mouth 12 is that axial cut-outs forms owing to magnetizing, each silicon steel sheet can scatter because of tension force in incision, be the raising effect that magnetizes, at mouthful 12 two ends of magnetizing respectively with tightening up tight constraint on the pull bar 13, two tighten up between the pull bar 13 and are connected firmly by copper supporting bracket 6, to prevent mouthful 12 flick of magnetizing.
