Q: Transformer parameter interpretation: I, temperature rise and cooling: transformer winding or the upper oil temperature and the temperature difference between the ambient temperature of the transformer, known as the winding or the upper oil temperature rise. Oil-immersed transformer winding temperature rise limit of 65K, oil surface temperature rise 55K. There are a variety of cooling methods: oil from the cold, forced air-cooled, water-cooled, tube, chip and so on. J, Insulation level: Insulation class standard. Insulation level of the method for the following example: high voltage rated voltage of 35kV level, low voltage rated voltage of 10kV level transformer insulation level expressed as LI200AC85 / LI75AC35, which LI200 said the transformer high voltage lightning impulse withstand voltage of 200kV, power frequency withstand voltage For the 85kV, low voltage lightning impulse withstand voltage of 75kV, power frequency withstand voltage of 35kV. Oaks High Technology Co., Ltd. The current oil-immersed transformer product insulation level LI75AC35, said the transformer high voltage lightning impulse withstand voltage of 75kV, power frequency Withstand voltage of 35kV, because the low pressure is 400V, can not be considered. K, the connection group label: According to the transformer one. Secondary winding phase relationship, the transformer winding connected into a variety of different combinations, known as the winding group. In order to distinguish between different groups, often using the clock representation, that is, the high voltage side of the voltage phase of the clock as a long needle, fixed on 12, low voltage side of the phase voltage as the clock short needle, (A) is a (triangular) joint, and the secondary winding is a (star) junction with a center point, and the group number is (11).

Q: How to understand the secondary side of the transformer: Primary side, is the primary, is connected to a fixed power grid. Secondary side, secondary conversion into what we need, or the power needed by the device. Secondary side output also has high pressure and low pressure points. The principle is that the transformer becomes the voltage we need to use.

Q: How many transformers are used in a hundred households?: Depending on the specific use of electrical power. First select the rated voltage of the transformer. The voltage on the high voltage side is equal to the voltage of the connected grid. The voltage on the low voltage side is 10% or 5% higher than the voltage of the low voltage side (depending on the voltage level of the transformer and the magnitude of the impedance voltage). Calculate the size of the load carried by the transformer (requires the maximum statistical load, the conversion of the operating load kW value into apparent power kVA). If two transformers are used, the capacity of each transformer can be selected according to 70% of the maximum integrated load. The transformer should be considered for the total load and leave the appropriate margin. Other brand name parameters can be combined with the appropriate consideration of the transformer product. For example: select 35 / 10kV transformer. Assuming a maximum load of 3500kW, power factor of 0.8, choose two transformers, capacity S = 0.7 × 3500 / 0.8 = 3062kVA, 3150kVA transformer can choose, the voltage ratio of 35kV / 10.5kV. Select the model from the catalog.

Q: What is the meaning of the Y D11 on the transformer?: Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).

Q: 2500KVA transformer bearing current how much calculation: Did not give the voltage data to transformer primary and secondary side rated voltage 10KV / 0.4KV as an example: Primary side rated current: I = P / 1.732 / U = 2500 / 1.732 / 10 ≈ 144 (A) Secondary side rated current: I = P / 1.732 / U = 2500 / 1.732 / 0.4 ≈ 3609 (A)

Q: How much W?: Ee22 transformer can be 20W. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.

Q: Hi, i need help on this issue: I bought a laser printer that operates at 1080W, but my 110V-240V step up/down transformer has a maximum capacity of 1000W, and now i cant even turn on my battery charger which uses 110V-240V. can anyone explain what went wrong?: It's not quite clear how your battery charger and step up/down transformer are associated or if you tried to use the step up/down transformer to power the laser. I'm guessing you tried and it didn't work and now your step up/down transformer doesn't work either. Since you've exceeded the power output of the step up/down transformer by using the laser, one of several things may have happened: 1. there is a safety fuse that has been blown in the step up/down transformer 2. there is a built-in circuit breaker that has been tripped in the step up/down transformer 3. you've damaged the circuitry/wiring in the step up/down transformer permanently 4. if the battery charger was plugged in at the same time (theorizing it is a separate device) it may have been damaged by the low power available by the power draw of the laser that the step up/down transformer was trying to supply You should always verify the power requirements of equipment to that of the supply before using them together and remember to calculate for total power of everything that is plugged into the supply that is being used at the same time. It is recommended that laser printers should not be plugged into power strips or surge protectors unless they are specifically designed for that heavy of a power load as most are not. If you haven't already, try removing them all from power for a few minutes or a couple of hours and then try plugging them in one at a time to a standard wall outlet to see how they respond. I would have to see them all to evaluate specifically what was wrong. Best of luck.

Q: Exactly what is the storyline of the Transformers. As far back as I know, there were two brother, Unicron and Primus who fought each other because Unicron wanted to suck up Universes. But where did these two come from? Does it even say?: I am a fan but I haven't been able to find that out myself, if you find out let me know.

Q: Hello everyoneA 240-110 stepdown transformer is used with quite a lot of equipement in my home and I have recently become a bit concerned about the effects that they have on the equipement.Thanks to some web page I stumbled across saying that transformers can 'overheat' your equipement etc.And since most transformers aren't made by any big name brands, there really isn't a way to tell if the one in posession is a 'high quality' one or not.So my question is, do transformers actually damage your equipement?Anyone have expertise in this area?Thank you very much.: All transformers do is change voltage. As long as the equipment you are using is rated for the output voltage of the transformer, there shouldn't be any problems. There is a small possibility that you might get a little bit of humming and line noise from the transformer's windings, and if you're concerned about that, such as with audio equipment or computers, you can use a line conditioner to filter out the noise. I'm not sure what kind of equipment you mean. If you mean equipment that uses large motors or other inductance devices with a low power factor, I have heard that it can cause buckingbut really this is more of a danger to the transformer than the equipment. So, basicallyNO, a transformer isn't going to cause any damage to equipment as long as it's rated for the output voltage of the transformer.

Q: I want to get the asus transformer, and on the web, there is stuff like asus transformer prime, and i want to know the differences between both and the negatives and positives of each. Asus transformer prime is $100 more than the asus transformer, so I want to know if it's worth it or not. Thanks!: Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.
