Abstract
The invention includes at least a primary winding and a secondary winding, where the primary winding are separated into several segments by several taps, including even series-parallel segments as well as several tap segments, the series-parallel switches are led through cables to series-parallel switches, and the tap segments are led through cables to tap switches, it adjusts the series-parallel switches to connect in series or parallel with each series-parallel segment so as to implement voltage conversion and adjusts the tap switches to cut off or connect parts of the tap segments so as to achieve the purpose of increasing/decreasing number of turns and then implement fine voltage adjustment, thus making the turn voltage and output voltage constant as a transformer operates at high and low voltages. Its output voltage is stable, its operation is reliable, its resistance is low, it makes full use of number of winding turns, its road loss is low and it has the characters of small bulk, operating convenience and so on.
Description
Technical field:
The invention belongs to and a kind ofly be suitable for two kinds of different voltages and transformer that output voltage remains unchanged, belong to transformer manufacture technology.
Background technology:
In existing power transformer product, the electric pressure and the transformation ratio of a common transformer are fixed, and one time winding can only be got a kind of electric pressure, induces the another kind of voltage of secondary winding, and the number of turn and common circle voltage remain unchanged always separately for they.But some areas abroad, electric power is a kind of rival commodities, the user can select different Utilities Electric Co.s, it near the transformer the different electrical network of two-way, two kinds of different voltages are provided respectively, even the user wishes that under the situation that output voltage remains unchanged with voltage transformer can switch between two-way voltage electrical network.Also have another kind of situation to be exactly, in places such as China Qinghai, Gansu, be faced with the possibility of electrical network upgrading, voltage changes normal voltage into by original off-standard voltage, is consistent with domestic other provinces.If present transformer can not be applicable to two kinds of obstructed voltages under the constant situation of output voltage, then regional transformer will all suffer exit after the electric network reconstruction, change the transformer that is fit to new electric pressure, cause huge waste.
But existing voltage regulating transformer technically at present, a kind of is to realize by the winding that increases voltage regulation function, as the patent No. is that 92216008 Chinese patent (single-phase adjustable transformer) is by increasing the purpose that a pressure regulation winding reaches pressure regulation, another kind of scheme is not increase new winding, to export section of winding, and adopt access or cut-out winding to reach the purpose of pressure regulation.Also have some other voltage regulating mode simultaneously, but all can only be applicable to miniature transformer, its architectural feature can not satisfy the electric pressure and the capacity requirement of power transformer.For above the whole bag of tricks, all there is common shortcoming, exactly when carrying out Winding Design, need calculate umber of turn and sectional area of wire (number of turn is many when getting high voltage, and electric current is big when getting low voltage) under the various design voltages respectively, umber of turn and winding sectional area all will be selected maximum design, when low voltage operation, remove the unnecessary number of turn by switch, be not used.Its umber of turn is many in a word, conductor cross-section is big, and small product size is big, and waste of material is serious.Simultaneously, pressure regulation process middle impedance and load loss also can great changes will take place, do not reach the purpose of saving metal material and energy, therefore can not get extensive use.
Summary of the invention:
The object of the invention is to overcome above-mentioned shortcoming provides a kind of primary side can adapt to two kinds of different voltages, and secondary side is exported a kind of burning voltage, and load loss is little simultaneously, and the low transformer of cost.
The present invention realizes by the following method: the present invention includes at least one winding and secondary winding and a shunting switch and a series parallel switch, one time winding is drawn some taps, winding is divided into plurality of sections, comprise even number connection in series-parallel section and several tap sections, each connection in series-parallel section size is identical, the tap of connection in series-parallel section causes on the series parallel switch by cable, the tap of tap section causes on the shunting switch by cable, by regulating in parallel or each connection in series-parallel section of connecting of series parallel switch, realize voltage transitions, by regulating the shunting switch excision or inserting part tap section, reach number of turn increase and decrease purpose, realize the fine setting of voltage, make transformer at height, keep the invariable of circle voltage and output voltage when voltage moves down in low two.The present invention can move two kinds of different voltages with winding of a transformer, compared with prior art, has reduced cost, can reduce simultaneously a winding resistance, made full use of umber of turn, reduce load loss.

Embodiment:
Be that example is described the present invention in detail below with the three-phase transformer.
As shown in Figure 1, when the present invention designs in three phases winding at primary side, each is divided into two connection in series-parallel sections mutually (as two sections of Fz1-Fz3, the Fz2-Fz4 of C phase winding, as shown in the figure), and several tap sections are (as the Z2 of C phase～Z9), with cable Fz1, Fz3, Fz2, Fz4 are caused the corresponding joints of series parallel switch 2 respectively, with cable Z2～Z9 is caused the corresponding joints of shunting switch 1 more respectively.When primary voltage operation high voltage, see the series circuit schematic diagram of Fig. 4, by by-pass cock 2 Fz0 and Fz1 are connected, Fz2 and Fz3 connect, and realize the series operation of two winding segments; When primary voltage operation low-voltage, see Fig. 3 parallel circuits schematic diagram, by by-pass cock 2 Fz1 and Fz2 are connected, Fz3 and Fz4 connect, and realize the parallel running of two winding segments, and the number of turn reduces for low voltage operation.In all cases, can be by regulating shunting switch 1 excision or insert part tap section between Z2～Z9, the number of turn of a winding is increased and decreased among a small circle, reach voltage pressure regulation purpose among a small circle, final purpose will keep secondary voltage constant.
A better embodiment of the present invention is the combination that is superimposed of series parallel switch 2 and shunting switch 1 levels as a whole, forms the double-layer composite change over switch, as shown in Figure 2.Wherein shunting switch 1 is regulated X2～X9, Y2～Y9, Z2～Z9, and series parallel switch 2 is regulated Fx0～Fx4, Fy0～Fy4, Fz0～Fz4.The two-layer compound switch that designs in this example has reduced volume of switch, has reduced the fuel tank volume, saves the space, and is easy to operate.
Output voltage stabilization of the present invention, reliable, cost is low, and the resistance of a winding is little, Take full advantage of umber of turn, load loss is low, has little, the easy to operate characteristics of volume.
