 Description

 

The application of 1140MVA/500kV Three-phase integrated 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 1140MVA/500kV Three-phase integrated 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 the 1140MVA/500kV Three-phase integrated 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:How do I select a transformer connection group?
Connection group can not be arbitrarily selected, depending on the primary transformer connection group. If the higher-level transformer for the star angle, the next level on the election star angle
Q:More on transformers storyWhere to turn?
Get the animated series. They totally rock!
Q:800kw motor how much transformer
Transformer power factor is generally 0.8 (also 0.7), then the total power transformer = 800 / 0.8 = 1000KW. According to the "Power Engineering Design Manual", the transformer capacity, for a simple load of a single transformer, the load rate is generally about 85%, so the above example, the transformer capacity = 1000/85% = 1176KVA, select 1176KVA above capacity transformer. If it is a single motor, due to the starting current, even if the measures taken, but also increase the corresponding transformer capacity. If the three-phase imbalance, but also a corresponding increase in transformer capacity.
Q:Which Autobots and Decepticons r going to be in Transformer-2?? Any ideas?
Soundwave. Optimus Prime 3
Q:630kva dry-type transformer rated current is how much
If it is a 10kV transformer, Then the rated current = 630 / 10.5 / √3 = 34.64A, which refers to a current, phase current
Q:Using mains transformers as speaker transformers in valve (tube) amplifiers?
you have 2 issues there. a million. Voltage; 2. Frequency. to that end, the two are against you. NZ has 50Hz mains frequency at 240V. in case you're relatively fortunate, the transformer could have twin windings on the universal, or a 220/240V. faucet. in case you do no longer understand what you're doing, seek for suggestion from an electrician or electronics tech. to have them examine regardless of if it relatively is twin voltage, and alter it. The frequency distinction can recommend incredibly much less performance, the transformer could get a sprint warmer in operation. even in spite of the shown fact that it may be high quality. you basically different thoughts are to alter the transformer (get one for twin voltages?), or use a 240/110V stepdown transformer earlier than it. The stepdown transformer could have a sufficient potential score for the interest.
Q:Transformer confusion.?
You are confusing VA (power ratings) with transformer ratios 120/16 7.5 :1 3300/120 27.5 : 1 So connect 7Vrms to 16 input to give output 1 52.5V Now connect this 120 (52.5V) output to the 120V input of the 120/3300 transformer The output should be approx 52.5 x 27.5 1444 Volts Use the 16/120 to step up and then the 120/3300 to step up again Take the function generator voltage to its lowest and measure at all points now gradually increase the generator voltage measuring at all points until you get what you want If the voltages are not as you expect then the VA ratings may be a problem Remember to be extra careful with High Voltages
Q:80 kilowatts of electrical appliances need much transformer?
The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can
Q:changing halogen light bulb contacts/transformer?
You are putting too much energy into the transformer. You need a circuit breaker in your circuit in order to reduce the amount of power that goes through the transformer. Because so much power is going through the transformer, it can only put out so much, so fast, and, therefore, your halogen lights are not turning it on. You can google circuit breakers or resistors, or take the lights in to any hardware store to see if they can fix them.
Q:Taiwan, Taiwan, the concept of transformer
Transformer refers to equipment; Taiwan change is installed in a place of the transformer, is specifically installed, running a transformer; Taiwan area refers to the regional range of variable power supply. Metering point is for the two sides to determine the installation of electric energy meter position, in general, the measurement point should be set at the demarcation point of property rights.
