Description

The application of 32MVA/220kV main 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 32MVA/220kV main 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 32MVA/220kV main 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:Hi, I replaced two 12V 20W halogen bulbs (wired in parallel) by two 3W 12V LEDs also in parallel. The problem is that the transformer (in a kitchen fume hood) seems to shut down when both LEDs are connect. It can take one but the two cause problems. I guess this might be caused by the very low resistances of the the 2 LEDs connected in parallel that short circuit the transformer? How can I reduce this short circuit without causing significant voltage drop for the LEDs? I tried using them in series but they won't work because they will then each have half the required voltage. Of course the idea is o find a solution that will also not significantly interfere with the energy savings associated with the change of halogen by LED. Btw, the LEDs are MR16 and have their own little voltage regulator/stabilizer circuit (or whatever that is).Thanks!: Low Voltage transformers (ELV or MLV) are tricky. Just because you have the voltages the same doesn't mean you have the right current being drawn by the LED's.It could be too low or too high. Were the original halogens MR16 form factor as well? I'm guessing the xfmr was specifically designed for a set voltage/current/power. Consider this: Two 20W halogens 40W. PowerVoltage*Current 2012*I I 1.67 amps through each bulb, 3.33 amps total drawn from the xfmr Transformers operate on the principle of Power in Power Out. The xfmr is probably designed to provide 40W, regardless of whatever current draw you put on the transformer. The LED's only need 6W from the xfmr. However, the xfmr probably doesn't care. It's still spitting out 40W at 3.33A. 0.5A (2*3W/12V) is all the LED's need. If the xfmr is still trying to provide 40W at 0.5 amps, the output voltage is compensated up to 80V coming from the xfmr. Most LED bulbs have protection for this in the engine, (the regulator/stabilizer as you call it), called over-voltage protection. This is probably whats causing the bulbs/transformer to fail. The problem is, especially with transformers, is that you must match the load. If the transformer is expecting a specific load and you give it something it can't handle, it'll either destroy the load or damage the transformer. The easiest way to avoid this is to always match the power of the original load to the load you intend to put in. 40W of halogens should be matched with 40W of LED. This is the gimmick with retrofit bulbs like the MR-16. You're not really saving any energy when you use retrofit bulbs. You just get a longer bulb life and a lot more light from the same power draw. LED lighting is a niche market. If you can't figure it out, wait a few months and LED lighting fixtures will decrease as the market is flooded with new product and becomes more competitive. I'd recommend investing in something like that instead of retrofitting.

Q:The core part of the transformer is composed of sub-and sub-components, which are generally divided into two transformers. Urgent, quick answer What is the core part of the "what" and "what" sub-composition ah? The "What" son, this "what" is to fill you ah.: The core part of the transformer is composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".

Q:Sichuan transformer manufacturer that a best?: Sichuan Meishan New Transformer Co., Ltd.'s products have the strongest load capacity, up to 200%

Q:I mean i want to watch transformers 3, do i have to watch 1 and 2 to enjoy the film ?: Yes, Transformers: Dark of the Moon follows Transformers and Transformers: Revenge of the Fallen. I don't think the story's so complex that you won't be able to follow it, but I would recommend watching the first two films if you have the time.

Q:i have an epcos 565-2 transformer and i want to know how much it will raise the electrical output of a standard 1.5 volt battery. i really do not know much about transformers, but i bought a motor, assuming that i would be able to do fun things with it, and i hooked it up to all the power i could(solar batteries, and numerous amounts of AA batteries) but it wouldn't spin anything that i attached to it more than probably 60 rpm. i bought a transformer to boost the power, and spin the motor much faster. the motor is graded for 3000 rpm maximum, but i just want it to be above 250. any help would be appreciated.: cule is totally wrong. Transformers only work with AC, not DC But even with AC, transformers do not boost power, they only boost voltage, with a lower current. Use more batteries, such as several 9 volt batteries

Q:1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?: Transformers animated ended last Saturday with Endgame part II. It was ended because of the movie coming out and Hasbro wanted to focus on movie merchandise. There's been some talk of maybe it starting up again after the movie or even a new cartoon.

Q:Does the production transformer require 3C certification? Does the country have any specific requirements?: The so-called 3C certification "China Compulsory Certification" Is China's mandatory product certification referred to. If your company's products can be sold publicly, without the need for 3C certification, it does not require mandatory certification.

Q:I have 14 gauge wire and some 28 gauge wire. Do both lengths of wire have to be insulated? Is it as easy as winding the 14gauge wire top to bottom and then do the 28 gauge wire top to bottom also? I'm guessing this is a step up transformer because the battery is going through the 14 gauge wire and then the lightbulb is hooked to the 28 gauge wire?Does the direction on winding matter at all? Say, CW for the 14g and then CW with the 28 gauge?: ferrite rods are not customarily used for transformers. at RF they are sometimes used as a core for a loop antenna. your application sounds like an ignition coil as you need an interrupter on the DC input (like points on a car ignition). the primary wire (14 gauge) would just be a few turns and not likely to run the full length top to bottom, the secondary (28 gauge) would be a lot of turns like 10 or 20 times as many. direction of winding would not matter in this application as capacitive coupling between the windings should be insignificant. all wire has to be insulated as a shorted turn spoils the transformer effect. wire used for transformers is customarily insulated with lacquer as plastic adds too much bulk to make tight windings. if you already have bare wire, then you made have some success by dipping the wire in lacquer paint first. it sounds like you are duplicating a project you have seen elsewhere. without knowing the source, it is hard for us to guess what the circuit parameters need to be for the transformer. but as i pointed out initially, i am skeptical that you will get this to function in the manner you are expecting. AC power transformers of the kind that use these wire gauges always use a torroidal core ferrite, never a rod. static DC cannot be transformed at all.

Q:I understand that transformers used to lower voltage for AC power transmission, simultaneously change both the voltage and current, but if such a transformer were in used in say a 12 volt dc power adapter that plugged into the wall outlet, then it would be counterproductive if the voltage lowering transformer upped the current as too much power would be dissipated, and a current boost would be unwanted, right? Same with transformer for PC power supplies. They must lower voltage without upping the current, right? Thanks a lot.: Transformers are power transmission devices. For a given load and turns ratio, a transformer will convert the input voltage and output voltage per the turns ratio. The current is determined by the load, not the transformer. This current is then transferred to the primary per the turns ratio. For example, if you have a 10:1 transformer that converts 120VAC to 12VAC, but there is no load connected, the current will be zero. So, while you still measure 12V at the secondary, no current can flow because there is nothing connected. If you connect a 1A load, the current at the primary will be one tenth or 0.1A. Thus, the power at the primary (120V * 0.1A) is equal to the power at the secondary (12V * 1A) or 12 watts. Of course, real transformers have losses, so the currents won't come out exact since a small amount of power is lost in the core of the transformer. Exactly how much power loss ocurrs depends on the construction of the transformer. So, transformers convert the primary voltage per the turns ratio, and the secondary current is transformed in the other direction.

Q:I know my user name indicates that I looooove X-Men but I loooove Transformers too. I was wondering if anyone knew who the transformer that comes out of the pool is. I have looked at the concept art and can't figure it out.: Looks like Megatron to me, but this movie is going to suck ***. It has shia lebouef in it and he is such a crappy actor.
