Abstract
The invention discloses a structure of a continuous main transformer with a station power supply, comprising a transformer winding and iron cores, wherein the transformer winding comprises a low-voltage winding and a high-voltage winding; and a station transformer winding is arranged at any position on a winding at any phase on a core column winding of each iron core. When the main transformer is designed, the station transformer winding is designed at any position on the winding at any phase on each core column winding of the main transformer according to the capacity and the voltage class of a station transformer, and thus the main transformer capable of supplying electricity for illumination, power utilization and being used for electricity transmission in a transformer substation can be provided, and a selection mode is added for the design of the transformer substation, simultaneously, the floor area and the cost of the transformer substation are saved; and two transformers are combined together, and thus electricity transmission and distribution systems are combined well, and the system efficiency is improved.
Description
Technical field
The present invention relates to a kind of transformer, the transformer that a kind of needs provide power supply for power transformation place relevant device, especially a kind of continous way main transformer tape station uses power supply architecture.
Background technology
Modern power systems is huge, a tight integral body.Require reliablely, have certain flexibility, operation should be simple as far as possible, convenient, reasonable economically, should have the possibility of enlarging simultaneously.In the transformer station of 110kV electric pressure 110kV is arranged at present, 35kV, 10kV loads, and also has the load of station electricity consumption simultaneously.The power load of wherein standing mainly is meant living load and lighting load.Conventional transformer station's design is confirmed to stand and is used the capacity that becomes at the total load according to power-equipment and lighting apparatus, designs a transformer separately.In master-plan and when planning, need to consider the station like this, position, and safe distance or the like problem with the floor space that becomes.Increase product cost virtually.Transformer station's capital construction of present large-and-medium size cities is had a large population and a few land at sub-civic center, and land resource is extremely valuable.Standing can increase cost with the independent design that becomes.
Summary of the invention
Goal of the invention: to the problems and shortcomings that exist in the prior art, the present invention provides a kind of continous way main transformer tape station of standing with transformer, minimizing floor space and reduction project investment that practices thrift to use power supply architecture.According to high-voltage variable power station power supply characteristics (be generally 110kV and become 10.5kV or 35kV change 10.5kV etc.), transformer station need provide illumination and equipment to use LVPS.Therefore general transformer station disposes a station in addition and use transformer, and The present invention be directed to present 110kV level and following electric pressure needs the improved transformer of standing with the transformer station of variable power source of design separately.
Technical scheme: a kind of continous way main transformer tape station uses power supply architecture, comprises Transformer Winding and iron core; Said Transformer Winding comprises low pressure winding and high pressure winding; Any position on any phase winding on the stem stem winding of said each iron core is provided with a station with becoming winding.
Said Transformer Winding comprises continous way, laminar, spiral and multistage layering winding type with the station with the coiling mode that becomes winding.
Said station is located at top, below, middle any position of low pressure winding or high pressure winding with the change winding.
Beneficial effect: compared with prior art; Continous way main transformer provided by the present invention tape station uses power supply architecture; When main transformer designs; Use the change winding according to the station with the capacity that becomes and station of any Position Design of electric pressure on wherein any phase winding on each stem stem winding of main transformer, satisfy electric current, voltage, the capacity of station, also satisfy the secured electrical distance simultaneously with heat light and power equipment.Transformer station's intraoral illumination and power electricity consumption can not only be provided, the main transformer of the usefulness of also transmitting electricity.For the design of transformer station increases a kind of selection mode, practiced thrift the floor space and the cost of transformer station simultaneously, two kinds of transformer group lump together, and have better made up electrical power trans mission/distribution system, have improved system effectiveness.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
As shown in Figure 1, main transformer structure of the prior art comprises low pressure winding 1, high pressure winding 2, transformer core 3.
As shown in Figure 2, transformer is used at low capacity station of configuration in existing transformer station, and is very little with transformer capacity because of standing; Be generally below the 80kVA; Only account for main transformer capacity 0.1～0.3%, its version is basic to be similar to main transformer, can with the shared iron core of main transformer, fuel tank etc.; As shown in Figure 2, stand with becoming top that winding 4 can be arranged on low pressure winding or high pressure winding 2, below, middle any position.Improve the back transformer and also have the station, can provide the station to use power supply with becoming winding.The main transformer winding can be the general any coiling mode of transformer industry with the station with the coiling form that becomes winding 4, includes but not limited to winding types such as continous way, laminar, spiral, multistage layering.
The present invention can be used for oil-filled transformer, also can be used for dry-type transformer.If oil-filled transformer is as shown in Figure 3, comprise that the station is with becoming sleeve pipe 10, bushing 11, low-tension bushing 12, standing with becoming winding 4, Transformer Winding 14, oil tank of transformer 15, transformer core 3, oil conservator 17.Stand with becoming the top that winding 4 is located at high pressure winding 2.
If dry-type transformer is as shown in Figure 4, mainly by transformer core 3, stand and form with becoming winding 4, Transformer Winding 14 etc.Stand with becoming the below that winding 4 is located at Transformer Winding 14.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
