Description

The application of the 150MVA/345kV three phases self coupling generator interconnection transformer.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 150MVA/345kV three phases self coupling generator interconnection transformer. 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 150MVA/345kV three phases self coupling generator interconnection 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 OLTCconstruction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of OLTC Transformer products.

Q: What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.: (3) split impedance: two short-circuit between the low-voltage winding impedance, that is, high-voltage winding open circuit, a low-voltage winding short circuit, another low-voltage winding power supply when the equivalent impedance. Where the reactance component is called split reactance.

Q: Transformer fever how to do?: ???National standard (oil-immersed transformer) the top of the oil temperature is generally adjusted at 85 ℃, if more than 85 ℃, to analyze the reasons: 1, if it is because the room temperature is too high, heavy load and other slowly rising, you can continue to run more than 85 ℃, but The maximum temperature can not exceed 95 ℃ (when the transformer core core or winding is 105 ℃, will seriously damage the insulation, shorten the life or burn the transformer); 2, the transformer running at 85 ℃, the transformer oil temperature and room temperature difference can not exceed 55 ℃, if it is over, may be a serious overload, the voltage is too low, the current is too large, internal failure, etc., continue to run will seriously damage the insulation, shorten the life or burn the transformer.

Q: I have been reading wikipedia and have gotten confused.Va.Number of Coils on side a---- ._________________Vb.Number of Coils on side bwikipedia mentioned how power companys use transformers for converting to high voltage power li nes then use transformers to bring the voltage back down.Focusing on the transformer that jacks the voltage upwirea-[side a-Transformerxyz- side b]-wirebso assum wireb is the high voltage power line.--Which side of transformerxyz would have more coils ? My guess is that side b has more coils then side a--Is it safe to say that the wattage of side a is equal to side b?--they said something about magnetic flux, does this just mean that the material connecting side a to side b has to be magnetic?--they said that the insulation wears down in transformers over time due to heat. what is causing this heat?--they said something about leakage and spacing of coils, what does this mean?tyVVVVVVVm: The previous answer is correct, but the following may be helpful. A transformer works by the linking of changing magnetic flux produced by one loop or coil (the primary winding) with another coil (the secondary). That is why transformers only work with alternating current or pulses. Magnetic iron has the ability to increase the magnetic flux produced by a coil. This is called its magnetic permeability and can increase the flux produced by factors of several thousand or more. Leakage flux in a real transformer is the amount of flux produced by the primary that does not link the secondary. This flux is wasted and reduces the efficiency of the transformer. Heating of the wire insulaltion not only comes from the resistive heat of the windings, but also the heat produced in the magnetic material (core) of the transformer. These losses are called eddy current and hysteresis losses and can be quite substantial. The reason that cores of transformers are laminated (stacked thin sheets of magnetic iron) is to reduce the eddy current losses.

Q: The main transformer is chosen in principle: Transformer selection, you can refer to the following, but still according to the actual production needs! 1, the number of transformers to determine ???(1), the number of main transformer to determine the principle is to ensure the reliability of power supply. When one of the following conditions is met, two or more transformers shall be installed. ???①, there are a lot of first-class load and although the secondary load but need to set from the security (such as fire, etc.). ???②, when the seasonal load changes greatly. ???③, when the load is large. ???For large-scale hub substation, according to the specific circumstances of the project can be installed 2 to 4 main transformer. ???When installing multiple transformers, it is appropriate to group the transformer according to the characteristics and changes of the load in order to flexibly switch the corresponding transformer group. Transformers should be operated in the sorted manner. Transformer low-voltage outlet of the neutral and neutral ground wire should be laid separately. For the convenience of testing, in the ground circuit, close to the transformer to do a removable connection device. ???(2), the general three-level load or capacity is not too much power and lighting should be a load with only one transformer. ???(3), when any of the following circumstances, can be dedicated transformer ???①, when the lighting load is large or power and lighting using a common transformer seriously affect the lighting quality and lamp life, can be set for lighting special transformer. ???②, single single-phase load is large, should be set single-phase transformer. ???③, the impact of a larger load, seriously affect the power quality, can be set for shock load special transformer. ???④, when the seasonal load (such as air conditioning equipment, etc.) about the total load of the project 1/3 and above, it is appropriate to configure a dedicated transformer.

Q: I can find them at Wal-Mart, but the smallest size they have is a 4/5 and that is too big. I am looking for 3T or 4T sizes.I saw a Transformers jacket in size 3T and 4T at Wal-Mart, but they didn't have any shirts.Thanks!: You can buy those Transformers or Ben 10 clothing in Kmart,Big W, some chinese shops and OKorder.

Q: I know there has been plenty of Transformers anime over the years, but is there any Transformers manga?: Have you tried googling it? Good luck! I remember seeing Transformers in JPN since I was little I think they've been around since the 80s. At least I've seen the toys in JPN since then.

Q: I would like to use this circuit to power arrays of high power LED'sI understand the properties required to power LED'sI have beginners knowledge in electric circuits and have done some research on this circuit. I have come across several posts stating it is dangerous to connect this circuit straight to mains power. I don't understand is what makes it is so dangerous?AndIf possible, how can it be made safe without using a transformer.: Your circuit will be fine without an isolation transformer if you connect a fast blow fuse, with the same current rating as your diodes or a bit less in the hot line to your voltage source. Your electric shock hazard is increased slightly without the isolation transformer. Your LEDs are vulnerable to power line spikes, even if you have an isolation transformer, but perhaps the transformer helps a little. An MOV rated about 190 volts in parallel with C, may provide some protection for your LEDs if the LED operating voltage is a bit less than 190 volts. Other MOV voltages are available at least rarely. Several hundred micro farads for C also suppresses spikes not only or your LEDs but also for other devices, connected to your ac source. A large value for C however means your diode bridge should be rated 25 amps or more.

Q: hey all , i have 2 phase welding machine fed from 30A 3 phase circuit breaker , at high loads above 40A CB cut off the Supply . the problem is i cant change the CB size bcoz it Contrary to legislation in the country . Can i used scott t transformer to balance the load at the main 3 phase ?: you're starting to be to be meant a single section welding device. This unit includes 2 supply lines. those lines may be linked to any 2 lines of a three-phse ability supply device.only connect one line to L1 and the different line to L2, only examine the line to line voltage of the flexibility supply. It must be the comparable by way of fact the welding device score, say, 380VOLTS, 50 Hz.

Q: about transformers: Leaving aside the double negative, the problem is your use of cancel - what do you expect - that it will go back to the generator and kill it? The transformer produces an output voltage which tries to do work against a resistance or inductance - the work it does produces a back EMF which the supply voltage works against so the generator has to do work. If there were no EMF in the primary, it would behave like a short circuit and blow the circuit - which is does in a small scale in the starting surge that you have to allow for when turning on equipment.

Q: I want to start watching Transformers Prime on TV, but I want all the backstory of just THAT universe, because i know there are MANY Transformer universes from Bay to Generation 1 to this. I just want to know what to read and watch before watching this series. Thanks!: Transformers Prime is set in a new continuity family, launched recently by Hasbro and also includes the War for Cybertron video games. It's really complicated, but in short, you only need to know that you do not need to watch, play or read any previous Transformers material to watch this series. Even the War for Cybertron games, which are supposed to be in the same continuity family, actually clash with the events of the TV series to the point that they're effectively a separate continuity. I myself have not played the game and it's perfectly fine. Also, I've provided links for the ultimate Transformers wiki so that you can do research on whatever aspect of the Transformers universe that you want. Don't worry, the show is fine to watch from the Darkness Rising: Part 1
