Description
Technical field
It the utility model is related to T ＆ D Technology field, more particularly to a kind of dry type or oil-immersed type transformer coil.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, it have a public iron core and with
Its several winding being crosslinked, and the locus between them is constant.When some winding receives AC energy from power supply, lead to
Inductance magnetisation is crossed, the electromagnetic induction principle of magnetic strength life electricity changes voltage, with same frequency, different voltage transmission in remaining winding
AC energy.Drum type brake transformer is one kind of transformer, and its primary structure is that iron core is arranged on centre, and coil is using iron core in
Heart ring-wound, each winding just form a circle, during as adjustable transformer, per circle on will be provided with tap, tap is got over
At most adjustable scope is wider.In the prior art the coiling to drum type brake transformer coil essentially using the wider one side of coil as
Then bottom surface forms a circle with this surface layer layer coiling, a subsequently coiling forms several numbers of turn, and concrete structure is with reference to figure 1.
Because the section of coil needs to meet safety standard, therefore the change that the size of coil can not be random, in order to obtain more preferable regulation
Precision would have to increase whole transformer, and so the increase of whole volume of transformer is to installing and using causing certain shadow
Ring.For this utility model be on the basis of whole volume of transformer is not changed by new winding method increase the number of turn with up to
To the raising of adjustable accuracy.
The content of the invention
The utility model is directed to deficiency of the prior art, there is provided a kind of cylindrical voltage regulation coil, can be existing
Improve the number of turn under volume as far as possible, obtain more accurate adjustable accuracy, solve to need when improving degree of regulation in the past to increase whole
The problem of individual device volume.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of drum type brake is adjusted
Line ball circle, including base, winding board is provided with described base, several circle windings are provided with described winding board, it is described
Winding is entwined by wire rod continuous horizontal, and described wire rod is the strip of rectangular cross-section, and described section includes narrower
A while and during wider b, described wire rod include with a while for wide A faces and using b as wide B faces, with the wire width
Narrower A faces are fitted in that the enterprising water-filling of winding board is flat to be wound winding.
In above-mentioned technical proposal, it is preferred that be both provided with tap on each described winding.
In above-mentioned technical proposal, it is preferred that be coated with insulated paint on described wire rod.
In above-mentioned technical proposal, it is preferred that be wound with empire cloth in described tap.
In above-mentioned technical proposal, it is preferred that described a while with the lenth ratio 1 during b：2~4.
Existing adjustable transformer is substantially using the wider one side of wire rod both B faces as bottom surface and then with this surface layer layer coiling
A circle is formed, because this winding method is the most simple and convenient, the phenomenon to misplace will not occur in the process of coiling.But with this
If necessary to the precision of increase regulation when kind of method carries out coiling, then need to improve the height of whole device, and the utility model
Coiling is carried out by bottom surface of narrower one side so that the number of turn improves original long side and times of short side ratio under identical height
Number, the precision both adjusted under identical height greatly increase.
Compared with prior art, the beneficial effects of the utility model are：It can be improved as far as possible under existing volume
The number of turn, more accurate adjustable accuracy is obtained, solve the problems, such as to need to increase whole device volume when improving degree of regulation in the past.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 2 and 3, a kind of cylindrical voltage regulation coil, including base 1, winding board 2 is provided with described base 1,
Several circle windings 3 are provided with described winding board 2, described winding 3 is entwined by the continuous horizontal of wire rod 4, described line
Material 4 is the strip of rectangular cross-section, and described section includes narrower a at 42 and wider b 41, described a sides 42 and b
The lenth ratio 1 on side 41：2~4.Described wire rod include with a while 41 for wide A faces 44 and with b while 42 be wide B faces 43, with institute
The A faces 44 for stating the narrower width of wire rod 4 are fitted in that 2 enterprising water-filling of winding board is flat to be wound winding 3.On each described winding 3
Tap 5 is provided with, empire cloth is wound with described tap 5.Insulated paint is coated with described wire rod 4.
As shown in figure 1, it is the state that adjustable transformer winding 3 is wound in the prior art, both with the wider width of wire rod 4
B faces 43 be fitted in that 2 enterprising water-filling of winding board is flat to be wound winding 3, be both provided with tap 5 on each described winding 3.In phase
With volume under, the quantity of tap 5 on adjustable transformer as described in Figure 1 is far fewer than taking out on adjustable transformer as described in Figure 2
First 5 quantity, both adjustable amplitude, the accuracy adjustable transformer of the prior art of regulation can not show a candle to the utility model.
