Abstract

The utility model discloses an add-subtract type energy-saving voltage regulator used for regulating voltage of the circuit with 220V or 380V power supply voltage. The voltage inducted by the voltage regulator and the power supply voltage are plus or minus through the phase relationship of the sine alternating current to regulate the power supply voltage. The voltage regulator is provided with two sets of windings. A primary winding is connected to the power. A junction point in a secondary winding is connected with one end of the primary winding. When the voltage regulator works, the junction point is communicated with one end of the power. A movable contact can arbitrarily move on the secondary winding and is used as one end of the output voltage. The end and the other end of the power form the output part of the voltage regulator.

Description

Add-subtract type energy-saving voltge regulator

The utility model relates to a kind of electrical equipment of adjusting voltage.Promptly be used for exchanging 220 volts and 380V circuit and adjust the voltage regulator of voltage.

In the ordinary course of things, because the difference of mains supply situation and the influence of power load, supply voltage (220 volts and 380 volts) is not a rated value, but on the low side or higher phenomenon is arranged.For guaranteeing the normal operation of consuming device, often dispose voltage regulator.Before the utility model was made, used voltage regulator was the self-coupling type voltage regulator usually.As seen from Figure 1, the coil of importation and output is a same group of coil, and A, B are input, C, D are output, and B and D are the public end of input with output, and C is a movable contact, can move at coiler part, changing the height of output voltage, thereby play the purpose of pressure regulation.When using this voltage regulator, the power of voltage regulator should like this, just make that the volume of voltage regulator is big greater than the power of electrical appliance, Heavy Weight, and the material of consumption is many; In addition, use this voltage regulator, the electric current of load all flows through the coil of voltage regulator, the electric energy (being commonly called as copper loss) that consumes is just some more, simultaneously, iron core part is also more because of the electric energy (being commonly called as iron loss) of magnetic hysteresis and the loss of eddy current institute, these in vain the electric energy of loss be converted into heat again, this is especially unfavorable to improving the assembling machine performance.Because present voltage regulator cost is bigger, can not popularize family and use, often there is the fluorescent lamp can not normal starting, the disadvantage of household electrical appliance cisco unity malfunctions such as television set.

In order to overcome above-mentioned weak point, provide a kind of plus-minus formula energy-conservation voltage regulator.The energy-conservation voltage regulator of this plus-minus formula is to add and subtract according to the phase relation of sinusoidal ac to adjust the voltage height.When supply voltage is on the low side, if voltage regulator of the present invention provide one group with supply voltage frequency, voltage that waveform phase is consistent, with its addition, replenish the insufficient section of supply voltage; When supply voltage is higher, as long as voltage regulator of the present invention provides one group of frequency, waveform with supply voltage identical, and the opposite voltage of phase place subtracts each other with it, promptly balance out the part that supply voltage exceeds, thereby reach the purpose of output rated voltage.

The effect of the energy-conservation voltage regulator of the utility model plus-minus formula: owing to adopt plus-minus formula voltage regulator, the voltage that this voltage regulator provided only accounts for the sub-fraction of output voltage, that is the power born of this voltage regulator only accounts for the sub-fraction of power output.So generally speaking, the power of this voltage regulator self need only electrical appliance power 1/10th to 1/5th can be competent at a job.

The description of the energy-conservation voltage regulator of plus-minus formula of the present utility model is as follows: the entity of the energy-conservation voltage regulator of plus-minus formula is a mutual inductance type voltage regulator, and from Fig. 2, A, B are elementary winding, and on annular iron core, elementary winding directly connects power supply with framework for it.E, F are secondary winding, and its circle is enclosed the land around annular iron core by one.One tie point D is arranged on secondary winding, and it links to each other with an end of elementary winding, and it communicates with an end of power supply during work.C is an armature contact, can slide arbitrarily on secondary winding.C forms output as an end of output voltage with the other end of power supply.If armature contact C moves in D, E zone, output voltage is risen; And armature contact C moves in D, F zone, and output voltage is descended.Like this, the variable voltage of responding to by this voltage regulator directly goes with the supply voltage addition, subtracts, thereby reaches the purpose of adjusting the back output rated voltage.

Be further elaborated below in conjunction with drawings and Examples.

Description of drawings:

Fig. 1 is the schematic diagram of the present self-coupling type voltage regulator that uses.

Fig. 2 schematic diagram that to be the energy-conservation voltage regulator of plus-minus formula of the present invention use in 220 volts or 380 hint roads.

Fig. 3 is the schematic diagram that the energy-conservation voltage regulator of plus-minus formula of the present invention is used in the three-phase power line.

Adding and subtracting the energy-conservation voltage regulator of formula with Fig. 2 uses as embodiment in 220 hint roads.Iron core is GE1 sections core (being common square transformer core), and tongue is wide 32 millimeters, changes thick 50 millimeters, and power can reach 100 watts, every volt 3.5 circles.Elementary winding A, B are 770 circles, 0.49 millimeter of enamelled wire line footpath φ; 1.12 millimeters of secondary winding line footpath φ, per 18 circles (promptly 5 volts) are taken out one, totally 9 statures.One end of the 5th tap D and elementary winding joins.During work, elementary winding connects power supply, and D also communicates with an end of power supply.C is an armature contact, and it can contact respectively with 9 taps on secondary winding E, the F.C is an end of output voltage, and the other end of it and power supply is formed the output of this voltage regulator.C changes in the tap of secondary winding D, E part, can make output voltage raise 5 volts, 10 volts, 15 volts and 20 volts respectively; In the tap of D, F part, change, can make output voltage descend 5 volts, 10 volts, 15 volts and 20 volts respectively; According to need can, the buck scope also can enlarge, as uses the annular core coiling, it is just meticulousr to adjust voltage.Though the power of the voltage regulator of present embodiment own has only 100 watts, it can be with 500～700 watts load.Even it is bigger.

As a same reason, the energy-conservation voltage regulator of plus-minus formula also can be applied in the three-phase power line, and winding diagram as shown in Figure 3.

The advantage of the Add-subtract type energy-saving voltge regulator of utility model:

Because voltage and supply voltage two parts that output voltage is this pressure regulator to be provided form. And the voltage that this pressure regulator provides only accounts for the very little part of output voltage. That is to say that power output that this pressure regulator is born only accounts for the very little part of bearing power, namely 1/10th to 1/5th, and most of power is directly provided by power supply, thereby Add-subtract type energy-saving voltge regulator is littler than common pressure regulator volume, in light weight, few with material, price reduces, and is particularly suitable for family and popularizes use. Because the power of Add-subtract type energy-saving voltge regulator itself only has ten of bearing power / one to 1/5th, thereby Add-subtract type energy-saving voltge regulator reduces than the electric energy loss of common pressure regulator, caloric value reduces.
