Description
The utility model relates to a kind of voltage regulator.
China's utility application discloses the saturated magnetic shunt formula of a kind of short magnetic circuit shell-type arc welding transformer for No. 90205820.7, the short magnetic circuit shell type core of this transformer adopting constitutes main magnetic circuit, two magnetic shunt iron cores and two magnetic shunt field windings are set, on the stem stem primary and secondary winding is set respectively up and down at main magnetic circuit, regulates the size of welding current by the magnetic shunt field winding.With regard to above-mentioned existing transformer, though can realize voltage regulation function, structure is comparatively complicated, thus the defective of existing.
The purpose of this utility model provides a kind of magnetic voltage regulator of structure tube list.
The purpose of this utility model realizes in the following manner: increase a magnetic shunt iron core between the iron core twin columns of transformer, coiling direct current winding on this magnetic shunt iron core, first and second winding of transformer respectively winding in both sides by the iron core of magnetic shunt iron core disjunction.Its working mechanism is: when not having current flowing in the direct current winding, the exchange flux that produces in the transformer stem stem by magnetic shunt shunt, there is not the magnetic flux coupling basically in first and second winding, the secondary winding output voltage approaches zero; When flowing through maximum direct current in the direct current winding, the magnetic saturation of magnetic shunt own, magnetic resistance increases, force exchange flux to withdraw from magnetic shunt and itself have the loop of one's own along stem stem and yoke portion, between this moment two windings coupling the strongest, secondary winding output ceiling voltage.Specifically, magnetic voltage regulator of the present utility model is except that being arranged with winding and secondary winding on the pillar iron core, also between per two pillar iron cores, be horizontally arranged with the magnetic shunt iron core especially, be wound with the direct current winding on this magnetic shunt iron core, a described winding and secondary winding lay respectively at the both sides of magnetic shunt iron core.In the utility model, when the pillar iron core is two, just only be provided with one across the magnetic shunt iron core between two stem stems.When the pillar iron core surpasses two (as three), then can be between per two stem stems magnetic shunt iron core of horizontally set, and correspondingly on each bar magnetic shunt iron core, the direct current winding is set.
Magnetic voltage regulating transformer of the present utility model is compared with aforementioned existing product, and it controls the magnetic flux degree of coupling of first and second winding by the size that changes magnetic resistance, and then changes the output voltage of secondary winding, has characteristic of simple structure.In addition, this magnetic voltage regulator also has the following advantages: 1, range of regulation is big.Range of regulation reaches 19 times, substantially exceeds required standard.2, the reaction time is fast.Being pressure regulation time Chang Xiaoxiao, only is 0.1 second.3, wave distortion and harmonic components are little.Because the direct current flux in the magnetic shunt has the loop of one's own in member, and always become an angle of 90 degrees with exchange flux, can get rid of the influence of direct current flux to exchange flux, thus the waveform of exchange flux not because of influence of direct current changes, it is sinusoidal wave that the voltage of output, current waveform are essentially.4, efficient height.Because These characteristics, the waveform of direct current winding does not have any influence to interchange, and the thermal loss that dc pulse width is controlled in the magnetic shunt is just few, thereby has improved efficient.5, volume little, economize with material, it almost is equal to common transformer with the material amount.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of voltage regulator among the embodiment.
Fig. 2 is the A-A profile.
Fig. 3 is the B-B cutaway view.
Shown in Fig. 1～3, the band magnetic shunt magnetic voltage regulator in the present embodiment is arranged with winding 2 and secondary winding 3 on pillar iron core 1.In the present embodiment, between per two pillar iron cores, be horizontally arranged with magnetic shunt iron core 4 especially, on this magnetic shunt iron core, be wound with direct current winding 5.Winding 2 and secondary winding 3 lay respectively at the both sides of magnetic shunt iron core 4.Pillar iron core 1 is three in this example, and is corresponding with it, and the magnetic shunt iron core 4 of horizontally set is two.During the electric current that in regulating direct current winding 5, passes through, i.e. the voltage of scalable secondary winding 3 outputs.
