Abstract
The utility model relates to an add subtract typed voltage regulator, a primary winding L is directly connected with the power source, S is a secondary winding which is wound on the external layer of the primary winding, E is a moveable terminal vertex which is contacted with the primary winding, one phrase of the input end of the power source is connected with a single-pole double-throw switch that throws to the both ends of the secondary winding respectively, E and the other phrase of the power source act as the output voltage. The utility model has the advantages that the add subtract typed voltage regulator is smaller in volume, lighter in weight, less material consumption and lower price than the existing voltage regulator, the self power of the add subtract typed voltage regulator is only one tenth to one fifth of the load rate, therefore, the add subtract typed voltage regulator has less electric energy consumption and less heating power than the existing voltage regulator.
Description
The utility model relates to a kind of electrical equipment of adjusting voltage.Be particularly useful for adjusting in 220 volts of alternating currents and the 380V circuit 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 is not a rated value, but on the low side or higher phenomenon is arranged.For the normal operation of protection consuming device, often dispose voltage regulator.Before the utility model is made, usually used voltage regulator is the autocoupling type voltage regulator, 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, B and D are the public end of input with output, and C is an armature 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.
In order to overcome above-mentioned weak point, a kind of plus-minus formula voltage regulator is provided, this voltage regulator is to add and subtract according to the phase relation of sinusoidal ac to adjust the voltage height.The voltage that this voltage regulator provided only accounts for the sub-fraction of output voltage, and the power of this voltage regulator self need only electrical appliance power 1/10th to 1/5th can be competent at a job, thereby volume is little, and in light weight, it is few to consume material; The load current of this voltage regulator only partly flows through the coil of voltage regulator, and consumed power lacks relatively, and the complete machine performance is good.
The description of plus-minus formula voltage regulator of the present utility model is as follows: the entity of plus-minus formula voltage regulator is a mutual inductance type transformer.L is elementary winding, and it uses enamelled wire on annular iron core or square iron core.Elementary winding L directly is connected with power supply.S is a secondary winding, around the skin of elementary winding.E is that armature contact and secondary winding contact, and slides arbitrarily on secondary winding.End in the power supply input connects a single-pole double-throw switch (SPDT), connects the two ends of secondary winding respectively.The other end of armature contact E and power supply is an output voltage.When the P of single-pole double-throw switch (SPDT) and secondary winding termination was logical, the voltage of responding between PE was consistent with the phase place of supply voltage, as output voltage, plays the effect of boosting after this two parts magnitude of voltage addition.Logical when the Q of single-pole double-throw switch (SPDT) and secondary winding termination, then the phase place of the induced voltage between QE is opposite with the phase place of supply voltage, and this two parts magnitude of voltage subtracts each other the back as output voltage, has played hypotensive effect.
Be further elaborated below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the structure chart of the autocoupling type voltage regulator of prior art use.The input of A, B among the figure, CD are output.
Fig. 2 is the structure chart that plus-minus formula voltage regulator of the present utility model is used in 220 hint roads.1-input among the figure, the elementary winding L of 2-, 3-secondary winding S, 4-single-pole double-throw switch (SPDT) K, 5-armature contact E, 6-output.
Fig. 3 is the structure chart that plus-minus formula voltage regulator of the present utility model is used in the three-phase power line.
Add and subtract the utilization of formula voltage regulator in 220 hint roads as embodiment of the present utility model with Fig. 2.L is elementary winding (2), and on square iron core, iron core is a GE1 sections core with enamelled wire, and tongue is wide 32 millimeters, changes thick 50 millimeters, and power can reach 100 watts, and elementary winding L (2) is 770 circles, 0.49 millimeter of enamelled wire line footpath φ.Elementary winding L (2) directly is connected with power supply.S is secondary winding (3), and around the skin of elementary winding (2), secondary winding (3) is 162 circles, and per 18 circles are taken out one, totally 9 taps, 1.12 millimeters of line footpath φ.E is armature contact (5), and 9 taps of secondary winding (3) contact, and can go up arbitrarily at secondary winding (3) and slide.End at power input (1) connects a single-pole double-throw switch (SPDT) K (4), can connect the two ends P and the Q of secondary winding (3) respectively, and the other end of armature contact E and power supply is made output voltage.
Advantage of the present utility model: output voltage is voltage and the supply voltage two parts group that this pressure regulator provides Become. And the voltage that this pressure regulator provides only accounts for the very little part of output voltage. That is to say this pressure regulator institute The power output of bearing only accounts for the very little part of bearing power, and most of power is directly provided by power supply, because of And Add-subtract type voltage regulator is littler than existing pressure regulator volume, and is in light weight, few with material, and price reduces, and is particularly suitable for Family popularizes and uses. Because the power of Add-subtract type energy-saving voltge regulator itself only has 1/10th to five minutes of load factor One of, thereby Add-subtract type voltage regulator reduces than the electric energy loss of existing pressure regulator, caloric value reduces.
