2. General

With the advanced technology brought in from overseas, we developed SC9、SCB9 series and SC10、SCB10 series padding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy, therefore the resin insulating dry-type transformer is flame-retardant, explosion-proof, free from maintenance and pollution, and it is compacted and can go deep into load center, besides, with scientific and reasonable design and coating craft work, it has advantages of low partial discharge capacity, low noise, good heat dispersion and it can run over a long time with 125% rated load in the circumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault or the temperature is exceeded and switch off as the function of “black box”. It can be monitored and controlled by connecting it to the computer through its RS485 serial interface.

Therefore, it is widely used in the places such as hotel, restaurant, airport, power plant, hospital, skyscraper, shopping center, and residential areas and other adverse environments like subways, smelt and power plant, ship, offshore drilling platform, etc.

Q: What is the use of the lower part of the transformer made of rail?: Transformer parts are equipped with a roller. You can easily pull the transformer into or out of the transformer room. After the transformer is positioned, do not weld the wheels and rails. Another support also received.

Q: 10KV distribution transformer how to calculate the tap voltage: 10kV distribution transformer tap voltage can be Ue ± Ue X% (X is the percentage of each range of adjustment). General distribution transformer tap adjustment range of Ue ± 2 × 2.5%; tap for 1 - 5, the tap voltage is calculated as follows: 1 ----- 10+ (10 x (2 x 2.5%)) = 10.5 kV 2 ----- = 10 + (10 x 2.5%) = 10.25 kV 3 ----- 10kV rated voltage, 4 ----- = 10- (10 x 2.5%) = 9.75 kV 5 ------ 10- (10 x (2 x 2.5%)) = 9.5 kV Transformer tap on the high side, according to the needs of the low side to adjust the high pressure side of the tap position. If the low voltage side of the low pressure should be raised to 4 or 5, and vice versa to 2 or 1 up. Because the adjustment tap is used to change the transformer ratio. In the case of a transformer with a rated voltage of 10 / 0.4kV, its change ratio K = U1 / U2 = 10 / 0.4 = 25; when the secondary voltage is low, if the split is set to 4, the position K4 = U1 / U2 = 9.75 / 0.4 = 24.375, the primary voltage is still 10kV secondary voltage = 10 / 24.375 = 410V. Increased secondary voltage. In fact the adjustment of the split is adjusted by the number of turns of the coil, the change in the ratio and the number of turns of the secondary coil is constant. To reduce the secondary voltage, increase the number of turns of the coil.

Q: What is the meaning of the transformer capacity unit KVA?: KV.A is the capacity in the transformer KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW

Q: I know that a step up transformer (stabilizer) increases/decreases the voltage that is received from the main electrical lines thus allowing gadgets to work properly. Keeping this in mind will the following idea work:1.You start a motor with the help of a battery,2.The motor then turns a dynamo using a strap (connected like a chain on a bicycle) 3.The dynamo produces electricity, this electricity is sent through a step up transformer, this then increases the output of power received from the dynamo.4.This increased power is then sent to a set of plugs, where devices can be plugged in to use the increased power. One permanent plug/use will be to recharge the battery or to run the motor by using a changeover switch (battery to motor ---- output from dynamo to motor): Transformers do NOT increase power, in fact they lose power through various means. A step-up transformer will increase the voltage at the expense of the current. Ignoring losses, the power out equals the power in, so if the input is 10 volts at 10 amps (100 watts) and the output is 100 volts, the current must be 1 amp to maintain the same power. What you propose is just a variation on an old idea for perpetual motion. I remember thinking of it myself as a child. You can't get more power out of a system than the power you put in. Thanks to the losses inherent in any practical system, you always get less out. It is similar to the idea of using the hydrogen and oxygen, which gets called HHO by the scammers and the gullible, to power an engine which drives the car and the alternator that recharges the battery to drive the electrolysis.etc. Same system but with even more losses built in. Read about the Laws of Thermodynamics.

Q: i am recently watching transformers prime and i am a big fan of all transformers but now i am confused.i generation 1 and 2 was good then they ended.does transformers cybortron trilogy a sequel to g2 or new start and then is tranformers prime a sequel to transformers fall of cybortrons?: 1) In the G1 timeline we have a sequel series made exclusively for Japanese audiences. They completely ignore the events in the American ending and go in a completely different direction. 1) Transformers: Headmasters 2) Transformers: Super-God Masterforce 3) Transformers: Victory 4) Transformers: Zone Then there's Beast Wars and Beast Machines is a sequel/prequel to the G1 series. ___________________________ 2) Transformers: Robots in Disguise (RiD) aka Transfomers: Car Robots in Japan is a complete standalone series, no relation to any other existing TF series ____________________________ 3) The Unicron Trilogy is it's own timeline that has 3 series. US - JP Armada - Micron Legend Energon - Superlink Cybertron - Galaxy Force but the 3rd series, Cybertron, was originally a self-contained series, the American version edits the dialogue to make it appear as a sequel to Armada and Energon. Also, the character Override, who is female in the US version, is male in the Japanese. In other words in Japan the first 2 are in the same continuity and the 3rd is a another reboot.

Q: Step-up transformer, low-voltage winding put the middle, that is, low-high; Step-down transformer, medium voltage winding in the middle, that is, low high. For the step-up transformer, the input is low and the output is high or medium; the low-lying intermediate makes it possible to minimize the distance in the low-high, low-, thereby reducing the distance traveled by the magnetic energy, Loss, reduced low - high, low - in the leakage resistance, thereby reducing the low - high, low - between the short - circuit voltage percentage, thereby reducing the reactance, thereby improving the energy conversion efficiency of the transformer. For buck transformer, the input is high, the output is low or medium, similar to the step-up transformer, the optimal arrangement should be low, high, medium. However, due to insulation safety problems, the high voltage side must be placed at the outermost end. So the arrangement of sub-optimal way to low, medium and high.: In theory, these two arrangements can meet the needs of the operation, manufacturing the same difficulty. If it is a step-down transformer. Low - medium - high permutations are commonly used, while mid - low - high permutations rarely encounter.

Q: Transformer voltage range of 10.5 ± 2 * 2.5% kV and 10.5 ± 5% kV What is the difference: Two transformers of the same voltage range, but the tap is not the same, the previous one is 5-speed regulator, select the relatively small, more adaptable. The latter is the third gear regulator, sometimes with the actual time required to have the voltage difference, mainly to see that your load is stable and unstable. These two kinds of voltage regulator for the basic price of the transformer has no effect.

Q: Transformer rated capacity 500 / 750KVA (AN / AF) What does it mean?: Transformer under natural cooling conditions, the maximum capacity of 500kVA, air-cooled conditions, the maximum 750kVA A refers to air, N refers to the natural cycle, F refers to forced circulation

Q: I am throwing my sons 7th birthday party, and again this year it is Transformers. He is asking to have some unique foods as oppose to traditional party pizza. We, of course will still have a cake but I am drawing blanks to food ideas. Does anyone have any suggestions? Thanks in advance!!: Robot Party Food

Q: What are the serious consequences of transformer circulation?: The connection group number must be the same, the wiring group is different, the transformer secondary voltage phase is different, at least 30 °, the voltage difference will be a great circulation, burn the transformer.
