A low voltage coil 1, a high-voltage coil and a low-voltage coil 2 are sequentially arranged from an iron core inside out, wherein the low-voltage coil 1 and the low-voltage coil 2 are respectively provided with voltage regulation taps or connected with independent voltage regulation coils. The low-voltage regulation coil device of the traction transformer is provided with only one high-voltage coil, voltage of the low-voltage coils and voltage in voltage regulation are low, changers are mature in technology, so that the insulation structure is quite simple, levels of voltage regulation leads and insulation of the changers are low, design and manufacture can be realized easily, reliability is high, cost for design and manufacturing is low, and impedance deviations during limit tapping are consistent.
Description
Technical field
The present invention relates to a kind of traction transformer, particularly a kind of traction transformer low pressure voltage regulation coil device.
Background technology
At present; The traction transformer that uses in China all is high pressure pressure regulation (primary side); The traction circuit is 27.5kV (secondary side) to the voltage of track without exception; And give the line voltage of the three-phase electrical power system of traction line powering was 110kV (primary side) in the past mostly, and present oriented 220kV even 330kV Development Trend.
See also shown in Figure 1; The loop construction of traditional traction transformer high pressure pressure regulation is: be followed successively by low pressure 1 coil, high pressure voltage regulation coil, high-tension coil, low pressure 2 coils outward from iron core, because the electric pressure of high pressure voltage regulation coil, high-tension coil is all very high, therefore; All to guarantee very big distance between four coils; And high pressure pressure regulation lead-in wire all need increase distance to guarantee the insulation between them, insulation system and complicacy thereof, switch insulation grade height over the ground and to high pressure, low pressure; Design difficulty is very big, and reliability is low and cost is higher.And because i low pressure impedance deviation when limit tap that two low pressure are arranged in is also inconsistent.
In view of above problem, be necessary to provide a kind of traction transformer low pressure voltage regulation coil device that can overcome above-mentioned defective in fact.
Summary of the invention
The invention provides a kind of traction transformer low pressure voltage regulation coil device, simple in structure, insulation system is simple, and pressure regulation is convenient.
The present invention adopts following technical scheme:
A kind of traction transformer low pressure voltage regulation coil device is followed successively by low pressure 1 coil, high-tension coil, low pressure 2 coils outward from iron core, and wherein, low pressure 1 coil and low pressure 2 coils all carry tap changer or all are connected with independent voltage regulation coil.
Compared with prior art, traction transformer low pressure voltage regulation coil device of the present invention has following beneficial effect at least: in traction transformer low pressure voltage regulation coil device of the present invention, have only a high-tension coil; And the voltage of pressure regulation, low pressure is all very low; And switch also has existing matured product, and therefore, insulation system is fairly simple; Pressure regulation lead-in wire and switch insulation grade are low; Manufacture and design easily and reliability high, design and manufacture cost has great advantage, the impedance deviation also is consistent when limit tap.
Description of drawings
Fig. 1 is the structural representation of traction transformer high pressure voltage regulation coil device in the background technology.
Fig. 2 is the structural representation of traction transformer low pressure voltage regulation coil device of the present invention.
Embodiment
Below in conjunction with accompanying drawing an execution mode of traction transformer low pressure voltage regulation coil device of the present invention is done and to be further described:
See also shown in Figure 2; Traction transformer low pressure voltage regulation coil device of the present invention; Be followed successively by low pressure 1 coil, high-tension coil, low pressure 2 coils outward from iron core, wherein, low pressure 1 coil and low pressure 2 coils all carry tap changer or all are connected with independent voltage regulation coil.
In traction transformer low pressure voltage regulation coil device of the present invention, can find out that the present invention has only a high-tension coil, and the voltage of pressure regulation, low pressure is all very low; And switch also has existing matured product, and therefore, insulation system is fairly simple; Pressure regulation lead-in wire and switch insulation grade are low; Manufacture and design easily and reliability high, design and manufacture cost has great advantage, the impedance deviation also is consistent when limit tap.
Characteristics of the present invention and advantage thereof are:
1. with respect to the high pressure voltage regulating mode, adopt the low pressure voltage regulating mode simple in structure, dependable performance, and tap changer can use existing matured product;
2. reaching under the prerequisite of same performance, through calculating, it is about 20% that the comparable high pressure voltage regulating mode of low pressure voltage regulating mode is saved cost, economic performance and excellence thereof, and reliability is higher;
The above is merely one embodiment of the present invention; It or not whole or unique execution mode; The conversion of any equivalence that those of ordinary skills take technical scheme of the present invention through reading specification of the present invention is claim of the present invention and contains.
