The application of ±800kV (HY14) of UHV converter transformer can significantly improve the economy of the UHV substation, and matches well with the transmission capacity of UHV lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 1500MVA/1000kV UHV AC transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV Transformer” as a key scientific research projects, and entrusted BTW to carry out the research.
During the process of research and development, BTW adopted the advanced design technology and modular design, the transformer can be transported disassembly and with advantages of compact core and winding body, less transportation weight and low transportation cost, effectively solves the need of UHV construction in the transportation restricted areas. By using the most advanced 3D magnetic field calculation software, BTW performed detailed analysis and calculation for the magnetic flux leakage and eddy current loss of the transformer coil, iron core and oil tank steel structures. Besides, by using of the advanced electric field calculation software, BTW performed detailed analysis and calculation of main longitudinal insulation, and mastered the arrangement of the main longitudinal insulation of large capacity UHV transformer and the control of distribution of winding magnetic flux leakage. All of which make the products with low loss, low noise, small volume, strong anti short circuit ability, no local overheating and other significant advantages, and guarantee the long-term safe and stable operation.
The world's first on-site assembled large capacity UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of 1500MVA/1000k transformer, which marks BTW has fully occupied the world transformer industry technical peak. The successful development of the product filled the gaps in the domestic technology and met the urgent need of UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.
- Q:220 kv transformer capacity range,
- GB GB / T6451 made a detailed provision, the latest version of the 2008 revision. (Boost, buck), three laps without load (boost, buck), autotransformed (boost, buck), the two-lane, There are several types of auto-load (boost, buck) and so on, there are about 31.5,40,50,63,90,120,150,180,240,370,400 MVA several grades, but corresponding to different types of transformers, Capacity level is slightly different, do not know what type of capacity you ask the range?
- Q:Transformer Amorphous Alloy and Silicon Steel Sheet Advantages and Disadvantages
- The use of magnetic properties of the protruding amorphous alloy, used to make the core material of the transformer, and ultimately get a very low loss value. But it has many features that must be ensured and considered in design and manufacturing. The main body is the following aspects:
(1) amorphous alloy sheet material hardness is very high, with conventional tools is difficult to cut, so the design should consider reducing the amount of shear.
(2) amorphous alloy monolithic thickness is very thin, the material surface is not very flat, then the core fill factor is low.
- Q:Transformer turns around the number and how much V is calculated
- Transformer turns around the number and how many V calculation method:
1. Find the number of turns per volt:
Number of turns per revolution = 55 / core cross section
For example, the core section = 3.5 ╳ 1.6 = 5.6 square centimeters
Therefore, the number of turns per revolution = 55 / 5.6 = 9.8 turns
- Q:Can the transformer be replaced with a component?
- If you say the transformer is a small power frequency transformer, then you can use switching power supply instead. If the substation with high-power transformers, there is no thing to replace.
- Q:This transformer outputs AC or DC
- Hello, the transformer is normally working when the input and output should be alternating current, some inverter transformer input may be pulsating DC, but the output must be AC. Because the transformer is by electromagnetic conversion to achieve voltage conversion, the primary changes in the current to produce changes in the magnetic field, through the magnetic field changes in the magnetic flux in the secondary electromagnetic induction, induced secondary electromotive force, is the secondary output. Pure DC power through the transformer coil can produce a magnetic field, but can not produce a continuous change in the magnetic field, and the transformer from the primary induction to the secondary, the medium is the change of magnetic field changes in the magnetic flux.
- Q:Is the transformer a power adapter?
- No, the transformer should be a device that performs impedance matching in order to achieve maximum power transmission.
In turn, "power adapter is a transformer" is also unsatisfactory, at least the general power adapter contains a transformer.
As a power adapter requires a common power supply into a device required power, voltage, current, impedance and other aspects of the match, of course, it needs a transformer. Since it has the function of changing the voltage, call it "transformer" is no harm. I would like to say that the power adapter is not only transformer, it needs to achieve in addition to the voltage other than the parameters of the match, for example, the most simple general-purpose DC adapter in addition to transformer that there is a "rectification" process. The transformer, narrow sense that it is just a component only, like resistors, capacitors, transistors and so on.
- Q:Transformer oil filter method
- 2, vacuum oil filter to ensure that there is a certain number of power, taking into account the size of your transformer, oil pillow position level, the oil filter is too small may not go oil cycle
3, the oil circulation from the oil pillow on the opening of the valve, where the best open after the bandaged, to prevent other debris in the filter oil fall into the transformer oil pillow.
4, filter oil after a certain time, take oil samples. Qualified to stop the oil filter, add the oil inside the oil can be closed after the oil pillow upper check valve. The transformer can be powered by one night after standing.
- Q:Know the rated capacity of the transformer, how to calculate its rated current?
- If it is a power transformer, its calculation method: rated current = rated capacity ÷ root 3 ÷ output voltage
Such as the rated capacity of 1250KVA, the rated current = 1250000 ÷ 1.732 ÷ 400 = 1804A
- Q:Transformer depreciation period is not specified?
- Article 60 In addition to the provisions of the financial and taxation departments of the State Council, the minimum years for calculating depreciation shall be as follows:
(A) houses, buildings, for 20 years;
(B) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;
(C) with the relevant utensils, tools, furniture, etc., for 5 years;
(D) aircraft, trains, ships other than the means of transport for 4 years;
(E) electronic equipment for 3 years.
Tax law and the provisions of the age is basically the same is not a big difference, but the provisions of the tax law more intuitive
Your company can choose according to the above I think is (b)
The above is the minimum depreciation period stipulated by the enterprise. The enterprise can choose the appropriate depreciation period according to the actual situation (not lower than the minimum standard stipulated in the tax law). But not to say that the enterprise can arbitrarily extend the depreciation period according to the "hundred years" requirement to depreciate because it is compensation tax The shortest possible time to recover the expenditure to enhance the taxpayer's operating capacity
- Q:My device has 50KW should be used with much transformer
- On the use of 50KVA transformer on the line, because your device will not appear at the same time the maximum power.
