Description
The invention relates to electric class voltage regulator, the particularly invention of contact mutual inductance voltage regulator.It is by the mutual inductance principle, utilizes the way of contact secondary coil directly to be carried out a kind of special voltage regulator of pressure regulation.
Existing voltage regulator, main use variable-voltage transformer, induction voltage regulator, moving coil voltage regulator, magnetic voltage regulator, silicon-controlled voltage regulation device etc. are arranged, the voltage adjustment characteristic that they have is good, but capacity is little; The capacity that has is big, but complex structure, cost height; The volume that has is little, in light weight, but the pressure regulation waveform is bad.In real work, most widely used model, variable-voltage transformer the most generally, the topmost characteristics of this voltage regulator are that volume is little, in light weight, easy to use, voltage waveform and voltage adjustment characteristic are good, and seem economical especially in voltage ratio near 1 occasion; But it is that electrical communication is arranged.Range of regulation is also little, and capacity is also smaller, so still be subjected to certain restriction on using.
Task of the present invention provides a kind of improved variable-voltage transformer, and it does not only have electrical communication, and range of regulation is big, and capacity is also big; And voltage ratio near one occasion can also be the self-coupling use.
Task of the present invention is finished as follows; It is identical with variable-voltage transformer substantially structurally, has just mainly increased by one group of secondary coil, becomes the mutual inductance principle by self-induction.Specifically be, by one group of primary coil on annular core, again by one group of secondary coil on primary coil, brush holder is fixed in the rotating shaft, again rotating shaft is put into the center of shell, and the also fixing bottom in the enclosure of the annular core that is wound with coil, and concentric with rotating shaft; The tie of primary and secondary coil is fixed on the terminal block of shell side, then brush is put into brush holder, and the metal surface of contact secondary coil, whole casing should fix; The top of shell have one with the concentric fixing dial of rotating shaft, use as indication for the pointer that is fixed in the rotating shaft; Insert power supply with primary coil this moment, and rotation is fixed on the uppermost handwheel of rotating shaft, just can change the position that electrically contacts of brush and secondary coil, thereby obtain level and smooth output voltage.The primary coil of this voltage regulator can be designed to connect separately a certain voltage, also can be designed to tap so that connect different brackets voltage; Secondary coil can be designed to the low pressure winding type, also can be designed to the high pressure winding type; Simultaneously, secondary coil also can be designed to tapped, is self-coupling usefulness so that also manage to make do; More as the secondary coil number of turn on around primary coil, when long-pending what position, plane is not enough, can be designed to the secondary coil of multilayer winding, can reach this moment by change over switch one-level or the several grades of smooth adjustment purpose of voltage on a large scale; As design jumbo, also can be with the contact mutual inductance voltage regulator of several equivalent capacity dress repeatedly, brush holder should be contained on the same shaft axis, primary and secondary coil adopts connection in parallel respectively; As design contact three-phase mutual inductance voltage regulator, and need to adopt the contact mutual inductance voltage regulator of three equivalent capacity repeatedly to adorn, brush holder also should be contained on the same shaft axis, and primary and secondary coil can adopt the star-star connection method respectively.
Contact mutual inductance voltage regulator of the present invention uses single phase alternating current power supply.It is to have increased by one group of secondary coil on the basis of variable-voltage transformer, so simple in structure, cost is also low accordingly; Simultaneously because therefore adjustable large-scale voltage solved the difficulty of regulating high pressure; Because primary and secondary coil does not have electrical communication, use in addition, especially be applied to save in some rectifying installations a rectifier transformer so can be used as transformer for hand lamp.
Further improvement of the present invention is also can to can be used as self-coupling and use or make its capacity to increase or make the voltage regulator of three-phase type by assembling, wiring, add ons.
