Description

The application of the 360MVA/500kV three-phase self coupling OLTC interconnecting transformer power plant.can significantly improve the economy of the OLTC substation, and matches well with the transmission capacity of OLTC 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 the 360MVA/500kV three-phase self coupling OLTC interconnecting transformer power plant. In order to make the products applicable to any OLTC substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity OLTC 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 OLTC 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 OLTCtransformer 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 OLTC Transformer’s right at the first time once again filled the gap in the field of OLTC transformer research after Chinese transformer industry overcame the difficulty of integral transport of the 360MVA/500kV three-phase self coupling OLTC interconnecting 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?: You are right. The value of a coil is measured in Henries and is determined by number of turns, size of wire, type of wire (commonly copper or aluminum). That is the reason you should not leave adapters and chargers plugged in. When not in use they should always be un plugged from power source.

Q: can someone please give me transformers war for cybertron ps3 controlls: Don't know

Q: Transformers, broken, how to repair: Some of the transformer buried inside an insurance, first look at the said

Q: Want to use in the air compressor, I do not know it?: Transformer oil can not be lubricating oil, because the main role of transformer oil insulation is not lubrication. The main role of transformer oil: (1) insulation: transformer oil has much higher than the air insulation strength. Insulation material immersed in oil, not only can improve the insulation strength, but also from the erosion of moisture. (2) heat dissipation: transformer oil specific heat, often used as coolant. Transformers run the heat generated close to the core and the winding of the oil heat up and down, through the oil up and down convection, heat dissipated through the radiator to ensure the normal operation of the transformer. (3) arc suppression effect: In the oil circuit breaker and transformer on-load regulator switch, the contact will produce an arc switch. As the transformer oil thermal conductivity is good, and in the arc under the action of high temperature can touch a lot of gas, resulting in greater pressure, thereby enhancing the dielectric arc performance, so that the arc quickly extinguished.

Q: Transformer capacity unit KVA? Transformer capacity unit KVA is how is it? 10KVA transformer, the maximum number of KW can be connected to electrical appliances? Supplementary - 2006-07-27 10:00:32 30KVA transformer, the maximum number of KW can be connected to electrical appliances? We plan to rent a workshop, there are power 380V, transformer capacity 30KVA. I want to install an electric furnace 75KW, welding machine 53KW, there are other small power appliances. Transformer capacity enough? I am full of transformer on the layman, please explain in detail, do not rhetoric.: What is the difference between kv, kva and mva? The kilovolt ampere (kVA) is the power measurement standard that is 1 kilovolt ampere. KVA is equivalent to the current in a circuit generated by the voltage of that line, usually measured in the transformer, that is he is a current unit. And kilowatts refers to the power of an electrical, that is, the power of the unit. The rated capacity represents the guaranteed value of the transformer output power under rated operating conditions and is the apparent power of the transformer. That is, the maximum output power of the transformer capacity, the transformer can not be the actual output power and capacity to be confused. The units are voltammetry (VA), kVA, and MVA.

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 ?: Transformer Phase Shift

Q: How to make a current transformer more linear? Except change the core.Thank you!: Ideal linearity is reached when B and H are linear. Use air as medium. It may give less output but linearity will be perfect!

Q: I have a transformer 12v and 12v need to reduce these further to be able to grow or shrink the rotational speed electromotor.Which device or component would be used to reduce the speed of electromotor?I making a mini escalators: A transformer has AC output, so first get DC, which needs a rectifier and capacitor. Following this is a voltage regulator using an LM317 (adjustable 3 terminal regulator). This can delivers ~1 amp. You should know what maximum current your motor draws under load. The first link is an example for 1.25V-15 V with an 18V transformer. Use a 12V transformer, and a 1000 ohm potentiometer as a variable resistor instead of 2000 ohms (R2). This will give voltages from 1.25V to 7.0V DC. Use the formula to calculate other resistors for a different voltage. Get the LM317 in a TO220 package, and you will need a heat sink, at least as big as in the picture. You can probably find a kit of parts for this in an electronics shop.

Q: I am in a verge of purchasing a house that is located very adjacent to a polyphase transformer. I hear of the stories that say about the adverse effects that are caused by these transformers to various electronic goods that are there in the house. Please clarify.: Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.

Q: What is the transformer absorption ratio (R60 / R15): Generally, the absorption ratio should be greater than or equal to 1.3 as the absorption ratio is acceptable.
