Description
The application of the 40MVA/20kV split auxiliary 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 200-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of the 40MVA/20kV split auxiliary 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 40MVA/20kV split auxiliary 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:hi can anyone tell me when installing/replacing a door bell transformer when switching off power supply at main source will that make it safe to work with the connections, it keeps telling us to turn fuses off well it dont have fuses its a circuit breaker. so do we turn circuit breaker off asweel as main supply into house. may be a silly question to ask but dont wnat any trips to A nad E lol thanks guys xxx
- Although, I have not tested a unit like you mention, I would get the 1.5a unit because that is the maximum it puts out in amperage. If your bell uses less its OK
- Q:I am powering a lighting system with a mixture of SCR dimmers and HID lamps. I am pulling approx 285 amps/leg at 120/208V through a 150 kVA transformer. The 120/208V service coming from that transformer is indicated to be 400A/leg, but it seems to get pretty hot at 285A.
- From your readings ,the transformer is within it's rating. Power Transformers are usually rated to operate at 75 Deg. C and above. Sometimes up to 95 Deg. C. The data and limit will be on the nameplate. 75 Deg. C is uncomfortably hot. 95 Deg. C. will burn you. Note; SCR dimmers WILL produce harmonic currents that will increase the 'neutral load' well above 'phase load' on 'common neutral' circuits, and might be producing some high frequency heating in that T/F.
- Q:Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?
- Air cooling can improve so much no sure no problem, and now a lot of transformer air cooling and self cooling ratio is 100: 80, 100: 70, there are 100: 60.
- Q:I just saw the mythbusters use a neon transformer to spark a methane explosion and the arch looked like a continuous irredecent light. So are neon transformers a part of neon lights? That and if you know, what is the inert gass inside the lights?
- Neon transformers step up the 120 Volt power to several thousand volts - enough to create a long spark in air. Every neon sign has a neon transformer either as part of it or very close by. The gas inside the neon tube and the color of the glass the tube is made of control what color the tube will shine. Neon gives a reddish-orange-ish color. Other gasses, such as argon, helium, xenon, krypton, etc., will glow different colors when enough voltage is applied to them, causing the gasses to ionize and produce light. Using colored glass tubes also controls the color. The inside of the tube may also be coated with a phosphor - much like a fluorescent lamp - to produce a particular color. For more information, see:
- Q:I thought the movie was great, but the death of Megatron seems really rushed and just unsatisfying? Agree?
- Well there's going to be a second one and there has to be a villian, right? Wait for the new one! comes out on june 26
- 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?

- Q:i have a bunch of transformers and they have the dates like i have optimus prime it says takara hasbro 1980-1982 and all the other toys say hasbro or takara! and most are made from 1982 -1985 also i have jet fire but the stamp doesn't say hasbro or takara but it does say bandai 1984!
- i'll answer throughly. bandai is a japanese brand which produce toys. but you asked how do i tell if my transformers are G1 or real. you can tell by its looks. g1 models looks like a box (quite square in shape), but the latest 1 looks modern.
- Q:How to use a multimeter to determine the quality of small transformers
- Generally with the smallest ohm file to measure whether the primary tap, if not, then damaged. Use the X10K stall above the ohm stalls to measure the primary and secondary, primary secondary and iron core for short circuit or leakage. If there is connectivity, then the insulation is bad or has been burned or breakdown.
- Q:How to distinguish between large, medium and small transformers
- Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on. Commonly used transformer classification can be summarized as follows: 1, according to the number of points: 1) single-phase transformer: for single-phase load and three-phase transformer group. 2) three-phase transformer: for three-phase system of the rise and fall voltage. 2, according to the cooling method points: 1) Dry-type transformers: rely on air convection for natural cooling or increase fan cooling, used for high-rise buildings, high-speed toll stations and local lighting, electronic circuits and other small-capacity transformers. 2) oil-immersed transformers: rely on oil as a cooling medium, such as oil from the cold, oil-cooled, cold water, forced oil circulation.
- Q:I have two questions:1. Can somebody please explain to me how transformer coupling is so good for maximum power transfer? Please be thorough. Is it because of the primary ac resistance and bjt output impedance being equal? I mean this should work because the power on the primary coil is the same as the power on the secondary coil so the power delivered to the primary coil which is the maximum power in this case, would ideally be delivered to the secondary coil, right? 2. And how can transformers be used to increase the overall voltage gain of a two stage common emitter based amplifier, something like
