Abstract

The utility model discloses a continuous main transformer power supply structure for a substation. The continuous main transformer power supply structure comprises a transformer winding and a core. The transformer winding comprises a low-voltage winding and a high-voltage winding, and a transformer winding for the substation is arranged at any position on any one-phase winding on a core column winding of each core. During design of a main transformer, the transformer winding for the substation is designed at any position on any one-phase winding on each core column winding of the main transformer according to the capacity and voltage level of the transformer for the substation, lighting and electricity for motive power in a substation can be provided, and the main transformer can transmit power. A selecting method is added for the design of the substation, simultaneously covered area and cost of the substation are saved, the two transformers are combined together, a power transmission system and a power distribution system are combined well, and system efficiency is improved.

Description

A kind of continous way main transformer tape station power supply architecture

Technical field

The utility model relates to a kind of transformer, a kind of transformer that power supply need to be provided to power transformation place relevant device, especially a kind of continous way main transformer tape station 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, and reasonable in economy 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 simultaneously the load of station electricity consumption.The power load of wherein standing mainly refers to living load and lighting load.Conventional Substation Design is determined the station capacity that becomes at the total load according to power-equipment and lighting apparatus, designs separately a transformer.Like this in master-plan and when planning, need to consider the station with the floor space that becomes, position, and safe distance etc. problem.Virtually increase product cost.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.

The utility model content

The utility model purpose: with not enough, the utility model provides a kind of continous way main transformer tape station power supply architecture of standing with transformer, minimizing floor space and reduction project investment of saving for problems of the prior art.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 to provide illumination and equipment LVPS.Therefore general transformer station disposes a station transformer in addition, and the present invention be directed to present 110kV level and following electric pressure needs independent design station to use the transformer station of variable power source and improved transformer.

Technical scheme: a kind of continous way main transformer tape station power supply architecture comprises Transformer Winding and iron core; Described Transformer Winding comprises low pressure winding and high pressure winding; Any position on any phase winding on the stem stem winding of described each iron core is provided with a station with becoming winding.

Described Transformer Winding and station comprise continous way, laminar, spiral and multistage layering winding type with the winding method that becomes winding.

Described 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 utility model tape station power supply architecture, when main transformer designs, according to the station with the capacity that becomes and electric pressure on each stem stem winding of main transformer wherein the station of any Position Design on any phase winding with becoming winding, satisfy the station with electric current, voltage, the capacity of heat light and power equipment, also satisfy the secured electrical distance simultaneously.Can not only provide transformer station's intraoral illumination and power electricity consumption, the main transformer of the usefulness of also transmitting electricity.For the design of transformer station increases a kind of selection mode, saved simultaneously floor space and the cost of transformer station, two kinds of transformer group are combined, and have better made up electrical power trans mission/distribution system, have improved system effectiveness.

Description of drawings

Fig. 1 is winding arrangement structure schematic diagram in the prior art;

Fig. 2 is the winding arrangement structure schematic diagram of the utility model embodiment;

Fig. 3 is that the utility model is used in the structural representation in the oil-filled transformer;

Fig. 4 is that the utility model is used in the structural representation in the dry-type transformer.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

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, at low capacity station transformer of existing transformer station's configuration, very little with transformer capacity because standing, be generally below the 80kVA, only account for main transformer capacity 0.1～0.3%, its version is basic and main transformer is approximate, can share iron core, fuel tank etc. with main transformer, as shown in Figure 2, stand with the top that becomes winding 4 and can be arranged on low pressure winding or high pressure winding 2, below, middle any position.Transformer is also used with the station and is become winding after improving, and the station power supply can be provided.Main transformer winding and station can be the general any winding methods of transformer industry with the coiling form of change winding 4, include but not limited to the winding types such as continous way, laminar, spiral, multistage layering.

The utility model can be used for oil-filled transformer, also can be used for dry-type transformer.If oil-filled transformer as shown in Figure 3, comprises 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 and be located at the top of high pressure winding 2 with change winding 4.

If dry-type transformer, as shown in Figure 4, mainly by transformer core 3, standing forms with becoming winding 4, Transformer Winding 14 etc.Stand and be located at the below of Transformer Winding 14 with change winding 4.

The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
