Description

The application of the 68MVA/500kV standby transformer power plant, 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 68MVA/500kV standby transformer power plant. 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 68MVA/500kV standby transformer power plant, 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:I personally thought transformers was worse but very similar to the avengers.: I liked the Avengers more.

Q:KW how to know how much transformer?: Know the number of KW, how to calculate how much transformer is needed. In general, our calculation is based on the nature of the equipment, the production process, the development prospects of the production enterprises to analyze the size of the transformer, some companies, how many kilowatts to choose the number of KVA, and some enterprises have all the equipment must boot Run, then, on the choice of a little bigger, the machinery industry enterprises, generally in accordance with the installed capacity of 4-5 fold to select the transformer capacity. For reference only.

Q:What is the primary side of the transformer: Step-down transformer: primary side of the high-pressure side (primary side) Secondary side refers to the low side (secondary side) Boost transformer: primary side of the low side (primary side) Secondary side refers to the high pressure side (secondary side)

Q:I know that vector groups basically determine the phase shift, and paralleling two transformers with different phase shifts is a genuine disaster.Some phase shifts can occur due to difference in the dot place, but for Wye-Delta connection the phase shift is 30 degree even with same dot on the primary and secondary. Why ?: This Site Might Help You. RE: What exactly causes the phase shift in transformers ? I know that vector groups basically determine the phase shift, and paralleling two transformers with different phase shifts is a genuine disaster. Some phase shifts can occur due to difference in the dot place, but for Wye-Delta connection the phase shift is 30 degree even with same dot on the

Q:Transformer how to do no load test: 3, through the no-load test can be found in the transformer the following defects: Poor insulation between silicon steel sheets. Between the core, between the pieces of local short circuit burn. Wear the core bolts or tie the strip, the pressure plate, the yoke and other insulation part of the damage, the formation of short circuit. Magnetic circuit in the silicon steel loose, dislocation, air gap is too large. Core multi-point grounding. The coil has turns, inter-layer short circuit or parallel branch turns ranging from ampere-turns and so on. Misuse of high consumption of low quality silicon steel sheet or design calculation is wrong.

Q:Can anyone explain what each wire does in this spicific microwave transformer: transformers is a movie, silly. your microwave is not an autobot, dont worry

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: Years ago 25+ Friedland bell transformers had two glass fuses 0.5amp,these very small glass fuses protected the transformer windings.These could be the fuses they are referring to,the main supply,as you have pointed out is fed from your circuit board. Isolate that breaker and remove the cover on your transformer and have a look for your fuses,these glass fuses are about half an inch long.Hope you are successful.

Q:I'll be going to Peru for 2 weeks and I was wondering if I could plug in my electronics over there. I read that they have both North American and European outlets and the voltage is 220 V and 60 Hz. My iPod wall charger and phone charger say 100~240 V (and my laptop charger says 100-240 V) and 50/60 Hz. Would I need to buy a transformer while I'm there so my stuff doesn't get all burnt out?: no you dont need to. its pretty much the same w electronics over there.

Q:Transformer Lightning: Dry coil internal coil will burst open, so that the transformer outside the four sides of the shell will be bulging. Cylinders on the porcelain will burn black, porcelain will be black and cracked. The line breaker is tripped.

Q:High-rise residential basement transformer noise is too large, how to solve, whether the need to shift, there is no other way to solve! Thank you as much as possible! If you have to do this project also please educated us!: Transformer noise is mainly caused by magnetostriction of silicon steel sheet. method: 1, choose a reasonable magnetic density; 2, core clamping; 3, pad to take shock measures; 4, the tank within the parts fastening, does not allow loose metal parts or standard; 5, all the accessories on the tank must be tightened; 6, the use of low noise fan; 7, the installation of the basic level. Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important
