Description

The application of the 31.5MVA/220kV single phase traction transformer, 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 31.5MVA/220kV single phase traction 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 31.5MVA/220kV single phase traction 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 you test this transformer with a multi-test meter? It was in a gong style door bell system. The 'clanger' unit has two windings withe the striker arm parallel to the end of the windings. Elaborate please. parts are difficult at my location.: Are you testing the transformer or the door bell solenoid coil? If it's the transformer: 1. ANY transformer has to be AC doesn't it? 2. 16V. x 10A. 160VA. 3. With your multi -tester set for continuity or OHMS: a. test both coils for continuity.(Low resistance) b. test both coils for non-continuity to the frame, (ground). There should be no flow, very high resistance. If it's the chime coils: Test both coils for continuity, (There will probably be a 'common' 'return' connection) and for insulation, (no continuity to ground - the frame.) If the above check out, the unit should work unless there's some mechanical damage. Look for a jammed operating rod etc.

Q: How we can check the output wattage of any voltage transformer? For example if we buy a voltage stabliser for television or A/C, how we can be certain that the output watts provided by the stabiliser will suit our appliance? Is there any device to check the output watts, if yes, then how to?Please help.: Watts is the volts x amps. You will know the supply voltage and you can use an amp meter to find out the amps. For example 230V x 3A is 690 Watts.

Q: I want you guys to tell me if the movie transformers its a good movie or not? Why?Thanks, See Ya!: First off, I did NOT want to see it. I'm not really into cars and all that kind of stuff. But my husband rented it last night and we watched it. And I will say I was surprised. I actually REALLY enjoyed it. It has a really good storyline and some pretty good acting as well! The effects are incredible too! Overall, it was a very good and entertaining movie! You should definately watch it. You won't be disappointed

Q: I bought my first ever Transformers toys which are the movie line, Ironhide and Barricade. However it is noted on the side of the box classes name; Voyager and Deluxe. What is the difference between both? I've search around the internet but none has given definitive description about it. All I know is that there is Deluxe, Voyager, and Leader class, and some more lower grades.Does the classes defines scale, size and complexity of the transformation?: Transformers Leader Class

Q: I need to run 12 amps through a 5-ohm electromagnet which means 60 volts must fall across it. I am building a power supply bridge rectifier circuit to fit my needs. I have a transformer capable of handling the wattage requirements but I am having trouble figuring out the amount of turns on the transformer to have on both the primary and secondary. The primary will be connected to an American outlet and I just don't understand how to get 60 volts DC out since the AC RMS voltage will be different than the rectified DC voltage.: If you want a different amplitude without using a resistor network, you probably need to transform before you rectify. You need a little more than half of the voltage you are starting with so not quite a 2:1 turns ratio. Make sure you have big enough wires for 60 A or they will get too hot.

Q: anyone have any pictures ideas on how to do a transformers cake???? i need one for this sunday any help would be appreciated: I would like to answer your question , If I could actually know what you mean.

Q: I have a power transformer and i forget where it came from. It has two leads from a wall outlet plug and then goes to the main (square) casing. there are three wires that come out the other side. They are from left to right, red,white and red. I assume its a 9v ac to dc transformer but am not positive. Can someone help me? I suspect that the white wire is ground. Any help would be great.: There's no reason to assume anything, except that the primary side (with the line cord and plug) is probably intended for 115 Volts, AC. If it's a transformer (rather than a power supply) it's not AC to DC at any voltage. Transformers convert AC to AC. With those colors on the secondary, there's a pretty good chance it's center-tapped. Red-to-red will be twice the voltage of either red-to-white. Nothing should be grounded to the transformer case.

Q: Hello, I'm new to electronics and I would like to know how is the current affected by a step-up or step down transformer. EX: Lets say you have a pure AC wave (60Hz , 25vac, 5A) hooked up to a 1:4 power transformer with a current rating of 10A, What will the voltage and current be and why? Thank you!: Given: Primary Voltage (Vp) 25 Volts Primary current (Ip) 5 Amps Turns ratio 1 :4 Calculated: Secondary Voltage (Vs) (Vp)*(turns ratio) (25V)*(4) 100 Volts Secondary current (Is) (Ip)/(turns ratio) (5A)/(4) 1.25 Amps Why? Because the turns ratio steps up the Voltage by a factor of 4. The resistance connected to the secondary is reflected back into the primary at a value such that (Vp)*(Ip) (Vs)*(Is). (25V)*(5A) (100V)*(1.25A). In this example the load resistance was 100V/1.25A 80 Ohms. But this 80 Ohms is reflected back in to the primary as 25V/5 5 Ohms. If no losses a transformer's resistance ratio always equals the turns ratio squared. Thus in this example; (80 Ohms)/(5 Ohms) (4^2). The primary current is always determined by the secondary current which is determined by the load impedance. But in this example the primary current (5A) was given and it was necessary to use the turns ratio to calculate the necessary secondary current that determined the 5A primary current. Additional comment: Hang in there Dr Jim. I was unable to follow your explanations in this particular problem but I am sure that every thing is going to be all right in the long haul of things. After all there are other things in life besides transformers.

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.
