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:I have a standard transformer with 7 wires:2 black2 red2 yellow1 red/yellow stripedWhat connections do these wires correspond to?That is, which should connect internally to the primary coil, the secondary coil, and coil-taps (based on the number of wires, I assume that the secondary coil is tapped).I must determine this in order to connect the wires (externally) appropriately.Any help is greatly appreciated!: The odds are fairly good that the black wires are primary, the red wires are one secondary, the yellow wires are another, and the striped wire is a center-tap on one of the secondaries. There is a standard ritual for identifying the characteristics of an unknown transformer: first, use an ohmmeter to identify which wires to a single winding, and which winding has the highest resistance. Next, apply power; the safest way is to use a 40-watt (or thereabouts) light bulb in series with a 120 volt source, and connect this to the highest-resistance winding. Now measure the voltages across each winding. That will give you the turns ratios, and you can get an indication from the physical size of the device as to how much power it can handle.

Q:I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you: What you see is normal, until the transformer is grounded the voltage floats. It is the same with the power for your house, the secondary of the transformer is normally grounded at the utility transformer, and at your ground rods, and to your water lines. X2 is the normal side grounded, although this has never made sense to me. You can imagine this, connecting one end of a flashlight battery to the frame of a car does nothing, you could then attach the other end of the battery to a light bulb, and the other bulb connection to the end of the battery or the frame, it only shorts if you connect the hot to the ground if you don't connect through a correctly rated load. Edit: Yes, ground it to the ground screw that the 208v ground wire is connected to, just to be clear, 208v connections H1 and H2 should not be grounded, and either x1 OR x2 needs be grounded, normally x2, grounding the transformer connection that is not connected to fuses.

Q:I am an avid stop motion animator, and I have been looking for Transformers toys to buy and animate. I have one, Deluxe Class Cliffjumper, and he's really great, pretty much the same as Deluxe Class Bumblebee. He works very well for stop motion. He transforms great, he looks cool, he's got good feet, he has stiff joints, and is very flexible and poseable. But I've been looking for another Transformer toy that can do the same job. So far I've bought two, and they have not been the same quality. I bought Deluxe Classes Barricade and Bonecrusher, but Barricade was too flimsy and Bonecrusher is too top heavy with terrible feet for poseability. Anyone familiar with the Transformers toys that could give me any ideas for the better toys for animations? (Under $40, please.) Thanks!: Do you mean the monster will say rates as he kills, or do you mean the full soundtrack would be rates. So, if he have been to have a communication, all of his communication may be sampled from different video clips? If it is the later subject, then i might propose getting Jack Nicholson video clips. His voice is so creepy and he has made maximum of flicks, you have have been given to be waiting to come across something you will need. If it is the former (the place he's in basic terms quoting type video clips), i admire: Wait'll they get a load of me! Jack in Batman right this is Johnny! Jack interior the Shining you are able to not shield the fact! Jack in some reliable adult males How a pair of superb interest of chess? the pc in conflict video games hi, Clarise.

Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means: Three-phase three-winding transformer high voltage, medium pressure, low voltage that the three sets of winding (rated) voltage level. Three windings have three windings per phase. When one winding is connected to AC power, the other two windings induce different potentials, which are used for loads of 2 different voltage levels. Power plants and substations are usually three different levels of voltage, so the three-winding transformer in the power system is widely used. Each phase of the high and low voltage winding are set on the same core column. In order to use a reasonable insulation, usually the high-voltage winding on the outermost layer, the pressure and low-voltage winding on the inner layer.

Q:does anywon kno if michael bay will bring back any robots that died from his previous movies? like jazz or bonecrusher or brawl anything like that. and i know that their making transformers 3 but does anyone know whats its going to be called or what are some new transformers? thank u for all ur answers. exept the crappy wons. il just delet thos. even tho u cant. ???: Okay let me start off by saying i'm not a nerd i just love transformers. lol. But from what I've heard the title is Transformers: Ascendents of Cybertron. The main villian is Shockwave. Megatron, Starscream and Soundwave are the only three that have been confirmed to be in the third one as of now. For the autobots Optimus, Bumblebee, Ironhide, Ratchet, Sideswipe, and the twins who Bay said weren't coming back are coming back. New characters for autobots include a robot named Silverbolt a red ferrari, a purple car, a blue car, and an autobot scientist. Also there introducing a new team of robots that will work with the autobots called the Wreckers, three nascars. There will also be two robot assasins ( decepticons ). And as for any returning unknown but i can tell you this they have comics that take place in between the movies and there coming out with a comic series called Transformers: Nefari or something like that which takes place after the second film and somehow Ravage the dog like decepticon who was killed by Bumblebee somehow comes back to life and Alice that robot chick from college somehow comes back and was captured by sideswipe after stealing an RV and was taking to NEST for tests. Oh and one more thing. The film is supposed to start of during the days where John F. Kennedy was president and something with a decepticon on the moon happens. But the film supposely says that the decepticons had something to do with the cold war and World War II. Hoped this helps

Q:Transformer is not the main and vice two coils? Resistance into which ah?: The significance of no - load power factor of power transformer The power transformer is likely to run without load, while the low power factor will increase the grid supply voltage. When the power transformer is unloaded, the no-load current is mainly used to establish the transformer core excitation and provide the excitation loss. The excitation current is part of the current current is reactive current, the general design, the power transformer power factor is low. When the power transformer winding side of the application of sinusoidal AC, the magnetic field is also sinusoidal changes in the magnetic field. However, the core of the transformer is a non-linear magnetically permeable material, so the field current that produces the magnetic field must be non-sinusoidal. Generally appear as "steeple". Figure 1 for a single-phase transformer no-load current waveform and its harmonic spectrum. Transformer no-load operation, the output power is zero, no-load power is equal to no-load loss. In the case of loss of fixed, the smaller the no-load current, the higher the no-load power factor. Therefore, the power transformer no-load power factor is higher, the better the no-load current is better. Increasing the no-load power factor is one of the main technical research directions of power transformer manufacturers, and reducing the no-load current is an important technical means to improve the no-load power factor.

Q:I have a 150 watt bank of photovoltaic cells that run at 12 volts (PWM mode non-mppt charge controller). My question is, by substituting a dc transformer (one that boosts current and steps down to 12v) for a current boosting mppt, can I run the solar panels at their full rating even though they are connected to a 12 volt battery bank? The 12v batteries, when directly connected to the solar panels, drop the output because the panels output their full current at a higher voltage.I am also wanting to apply this logic to a wind turbine that outputs a maximum of 30 volts dc. I am thinking that if the switching transformer works for the solar panels, it would also work to step down the wind turbine's harsh dc voltage to a current boosted 12v state. Would this theoretically work?: Transformers don't work on DC. You need a DC to DC converter.

Q:Is the transformer a power supply?: Here, are relatively speaking. 1, if your equipment behind the transformer, then the output of the transformer is your power. 2, if your equipment in front of the transformer (such as a substation or generator), then the transformer is your load. 3, for example: at home, the adapter (to the phone with a transformer device), it is for your phone, that is, power, you said the socket, it is the load. 4, but if it is necessary to define it as what equipment, then it does not belong to the power supply equipment (power supply with a large generator, a small dry battery). It is able to change the power supply mode of the device.

Q:i would say transformers alll the way: Thank you!!!! :D Definitely Transformers. Even the second one too. The second one was even better than the first one. The first Transformers will blow both Twilight movies away combined! Hehe, sorry I love Transformers I'm sick of hearing about that Twilight franchise:P

Q:I have a 120v X 24v step down transformer that is capable of supplying 30 amperes. I need to convert the output to dc to supply a project I am working on. I have a bridge rectifier capable of handling 10 amps continuously, but nothing that could handle the 30 amp output. What would occur if I put the rectifier on the input side (with no filter capacitors) and fed the xfmr the DC voltage with 120hz ripple? I suspect the xfmr wont like the 120hz input and generate excessive heat. Anybody know for sure? The xfmr has a laminated iron core and copper windings.: You are asking some strange questions. You do not have a very good understanding of transformers. A transformer ONLY works with AC. This is why Tesla argued for AC being supplied to houses. With a simple transformer, the voltage could be increased for less loss on transmission lines and then with a step down transformer, the AC could be brought into homes. Edison, on the other hand, loved DC and wanted all houses to be supplied with DC. Edison, in an attempt to prove Tesla wrong, invented the electric chair to show how dangerous the larger voltages would be. Edison even electrocuted animals in his electric chair to demonstrate the effects of higher voltages. Fortunately, Tesla won the argument, or we would not be able to transmit electricity over high power lines from generators to homes. Now, a rectifier in the strict sense, does not change AC to DC (with ripple) but simply reflects the negative wave to make it positive. Thus adding a DC component and doubling the frequency. The DC component will simply pass through the transformer (no heating) and the higher frequency will work just great with the transformer. In fact, you can make smaller transformers by using higher frequencies. This was a technique that Sony used many years ago to make great amplifiers and Fisher and Paykel use to make better appliances. (Other companies might also, but I am not aware of them.) So, your transformer will only see an input of 60 V AC and step that down to 12 V. Thus, you will not have the 24 v you need. Why don't you get a better bridge??
