Description

Material-saving transformer

Technical field

Transformer is manufactured

Background technology

After the mankind have found electromagnetic induction, just manufactured power electric generator, with various power machines, drive generator generating people electricity consumption that mains supply system is provided, from then on people just enter the epoch of electricity consumption, such electric power system is utilized electric energy and safe electricity consumption for high efficiency, and people have invented again transformer.

Progress along with human society, the appearance of various electrical appliances has brought convenient and has enjoyed to people's life, in order to meet the various voltage requirements of these electrical appliances, various transformers have just been manufactured now, there is power transformer, have power transformer, they have respectively again step-up transformer and step-down transformer.The high frequency transformer of using in electronics aspect in addition etc. all carrys out work by electromagnetic induction, and power and efficiency that electromagnetic induction produces are all how many with height, the wire circle of voltage height, size of current, frequency, the size of coil turn and whether relevant with the size of cored, iron core etc.No matter any transformer, their input and output are all deferring to wire circle and voltage is proportional.

Summary of the invention

Material-saving transformer, its feature: in the middle of the iron core at transformer coiling position, the outside in undercutting of length that accounts for greatly wound core total length 1/4 is gone, the degree of depth of surrounding about 1/4, the girth that makes this part iron core is original girth 1/2, Er Heng Load area is only original 1/4, at this, prescinded the secondary coil (output winding) that is coiled into transformation on the position of iron core with coil, the wire diameter of secondary coil be original same volume with on the whole complete iron core of power around 1/4 wire diameter of secondary coil, and secondary coil is identical with the original number of turns but saved 3/4 coil method than former transformer.

Under equal alternating voltage and frequency, the inductance of the just generation less than circle that coil turn is large is large, the voltage that it can bear is just high than the coil of ringlet, Here it is manufactures the parameter of transformer, the manufacture of transformer is all generally to coil on iron core-closed, the size of iron core has just determined the number of the coiling number of turns, large iron-core coil is just less, the little iron core line number of turns is just some more, the prerequisite condition of input (primary coil) of Here it is transformer, and output (secondary coil) just not necessarily, it is the amount doesn't matter, many is exactly step-up transformer, and few be exactly step-down transformer.The voltage of exporting is directly proportional with wire circle, and electric current is inversely proportional to exactly, and the voltage that is exactly the more outputs of output coil is just higher, and electric current is just less, and the voltage of the fewer output of wire circle of output is just lower, but electric current is just larger.

Just because of output does not possess, do not have the effect of bearing voltage, wire circle is the amount doesn't matter.Normal operation depends primarily on the primary coil of input, and primary coil has designed, and it just can defer to the theory that the number of turns and voltage are directly proportional.So I have just utilized this principle design to go out new efficient material-saving transformer.

It is the rule of transformer that wire circle and voltage are directly proportional, much no matter it has around Heng Load face, no matter be not always the case on great iron core in other words, only, in primary coil, the area of the number of turns is large, and its circumference is just long with line, the magnetic flux of induction is just large, induction reactance resistance just increases, and receive the just can the number of turns few of power supply, and number of turns area is little, its girth is just short with line, the magnetic flux of induction is just little, and induction reactance resistance is just little, so receive the number of turns of power supply, must increase.

Understood that the coil size that connects power supply only plays a part to mate with supply voltage with how many, and its output coil size is not important, main or coil number, directly form the Voltage-output of transformer, I have passed through experiment and have attempted reducing the Tie Xin Heng Load area in secondary coil position like this, so around the lead loop girth on iron core just along with minimizing, but as long as the number of turns is enough, the not oversize work that just can not affect whole transformer of the minimizing part of iron core is with normal.

The resistance of wire is directly proportional with length, with wire diameter, be inversely proportional to, the number of turns made of copper too, the same wire diameter, its longer resistance of length is just larger, and the same length, its larger resistance of wire diameter is just less.It is again the material-saving theory that has around this principle realized me, now with English, represent to lift a row explanation, such as there being now its output secondary coil total length of individual transformer, be L, resistance is H, wire diameter is O, 1/4 (as Fig. 3) of transformer core position occupied in the position of whole secondary coil, and power output is W, and efficiency is P.The secondary coil now designing, position is the middle in wound core position, the position that it accounts for is that 1/4 (as Fig. 1) will prescind at the iron core of this part, general surrounding is the size that 1/4 the length of side is gone in undercutting inwards, make the iron core girth prescinding reduce half, Er Heng Load area is original 1/4, around superincumbent loop length, just subtract and be a half like this, it is original 1/2, so total length is 1/2L, minimizing due to length, its resistance is also along with reducing half, so the resistance of resistance is also 1/2H, half that so just can reduce equally wire diameter realizes resistance and original identical resistance is all H, loop length subtracts and is a half so, in fact saving copper wire material half, coil minimizing wire diameter in this 1/2L length realizes identical with original resistance value again, actual 1/2 the copper wire material that goes at joint again, only 1/4 the copper wire material using so real, than originally having saved 3/4 copper wire material.But the voltage and current of making like this various factors process experiment output that can or can not have influence on original transformation does not all have to change, and power is still W, as long as your efficiency on the contrary that not only do not affect reasonable in design has also obtained corresponding raising.

Because the Ohm's law of complete closure is that internal resistance equals extrernal resistance, the power of its output is maximum, when resistance (D.C. resistance) resistance that the electrical appliance outside that is to say is added up equals the resistance of electric power system (battery, generator, transformer), the power of the circuit output of power supply is maximum, but if the electrical appliance resistance of outside is while being greater than interior resistance (electric power system), the electricity of outside is exactly that resistance is higher with regard to efficiency more greatly with device, and the fewer power consumption efficiency that just can outwards provide of interior resistance that is exactly on the contrary power supply is just higher.

Although having reduced wire diameter, material-saving transformer make resistance identical, but dividing, the resistance exchanging has pure resistance, induction reactance resistance and capacitive reactance resistance, so the resistance of material-saving transformer is with original identical, can the girth of coil and the area of iron core reduced, the induction reactance that it produces is also along with having reduced, and still efficiency aspect is improved thus.

Embodiment

On the wound core position of transformer, from mid portion, prescind the area of whole surrounding, making its Heng Load area is 1/4 original (as Fig. 2), girth is original half, i.e. 1/2 size, and the iron core prescinding is 1/4 (as Fig. 1) of former whole wound core length, this sunk iron core position is exactly the coiling position of the output secondary coil of transformer, its coil is around till the position of iron core is come in Plain, because the wire diameter of coil had deducted half than originally, so just around following the original number of turns, then two of line along iron core to an output, at whole iron core and secondary coil, all with insulating material, wrap again around primary coil (as Fig. 4) above the coil winding is also wrapped with insulating material, two of coil is to the other end output of iron core.

Because of the output winding voltage of transformer, just follow the number of turns and have relation, and and the length of the size line girth of circle there is no great relation, so can be artificial design reduces the use line length that reduces coil at the Tie Xin Heng Load area of secondary coil part, resistance because of coil is directly proportional with length again, with wire diameter, be inversely proportional to, so can reduce not only wire diameter when length reduces, reach resistance with original identical but also can reduce again the object that has reached material saving with wire material, do so coil method that whole secondary coil uses only original transformer 1/4, saved out 3/4 coil method.

If reasonable in design, the attention insulation of height, just can produce in this way range transformer, can make step-up transformer, can make step-down transformer, various power transformers can be produced, the various high frequency transformers that various power transformers (being three-phase transformer) and electronics aspect are used can be produced again.Being also noted that in addition particularly can not be oversize in the cut place of iron core, and the flux path that retain it can produce the close access of high-intensity magnetic field.This transformer can only be done output use, must not use conversely, the secondary coil of output can not be received to power supply exactly and use.
