2. General

With the advanced technology brought in from overseas, we developed SC9SCB9 series and SC10SCB10 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:I need a transformer that can produce 10 volts from a 1/2 volt change in the primary winding, but don't know how they are classified. The transformers I've seen on the internet give no clue of the winding ratio, just a serial number. Thanks.
This is a voltage step up transformer. What is needed is winding turns ratio of 1 to 20. This means that for every turn of wire in the primary, the corresponding number of turn in the secondary is 20 thus if a voltage of one volt is applied in the primary, the output will be 20 volts. It should follow that if the input is 1/2 volt, the ouitput will be 10 volt.
Q:Hello friendsi need transformer for my project (regulated power supply) i need 220 50hz ac input and 3 volt 50hz out put ac voltage is this possible.what is wattage of that rating transformer?thanks a lot
not enough information wattage is determined by the load demand and the efficiency of the transformer all we can tell for what you provided would be the step down windings turn ratios what is being powered on the 3 vac side of your project?
Q:"A transformer ratio is 110/11, then it is" "A transformer ratio of 110 / 10.5, it is" "A transformer ratio of 121 / 10.5, it is"
For example, 10KV system, the transformer primary winding rated voltage of 10KV and 10,5KV, secondary winding rated voltage of 10.5 and 11KV. 110KV system, the transformer primary winding rated voltage of 110KV, secondary winding rated voltage of 121KV. 220KV system, the transformer primary winding rated voltage of 220KV, secondary winding rated voltage of 242KV. and many more. 110KV is a winding, that is, 110 variable 10.5KV course is the buck variable. Secondary winding for the 121KV, that is, 10.5 variable 121KV course, the pressure has changed.
Q:The specification states that the 35KV substation is capable of obtaining the power supply after the main transformer is powered down. Therefore, in this case, the transformer used should be connected to the power supply side of the circuit breaker. My question is that the main transformer which, the main transformer is not connected to the power supply side of the circuit breaker?
Main Transformer: Main transformer, referred to as the main transformer, English name: generator step-up transformer, referred to as GSU transformer or GSU. The main transformer refers to a unit or substation of the total step-down transformer, its capacity is generally relatively large. Other transformers used as power distribution, commonly known as distribution transformers, the capacity is slightly smaller. On the main transformer protection, as the main transformer, in general, relatively large capacity, requiring a higher reliability of the work. For different capacity of the transformer, the required installation of the protection category is not the same. Transformers used: In general, substation high voltage switchgear need to provide 220V power supply, DC screen also need 220 power supply continued float. As in the operation of high voltage cabinet, there is no low-voltage power supply, so in the high-voltage cabinet set a very small capacity of the transformer. Thus providing the first power supply required for the operation of the high voltage cabinet. When the transformer is put into operation, the low voltage cabinet has the second power supply of the low voltage power supply circuit, and then automatically switches to the normal low side power supply as the operating power source. Features: Thermal stability, high reliability, long service life. Low loss, low noise, maintenance-free. Small size, light weight, less space, low installation costs.
Q:I am doing a school project of a Wind Turbine; and I need to show a transformer or what a transformer is in a wind turbine. I have just 1 question. WHY DO PEOPLE USE TRANSFORMERS?
Kiran okorder
Q:Transformer winding maximum temperature at?
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:anyone else see the trailor for this movielooks kinda goodthough, it may be were the transformers are bad guys, i dunno
Ehhhh I'm not sold on the concept yet. I want to see a real finished transformer first. I'm sure they'll get the transforming part right, but the sound I think will be wrong and stupid, and they'll probably look like those robots from Sky Captain
Q:Two different impedance of the transformer, parallel load how to allocate?
The impedance voltage is equivalent to the power supply resistance. Two impedance voltage is not equal to the parallel operation of the transformer, the impedance of the load distribution of small, low impedance voltage transformer load distribution. Basically inversely proportional. Generally the same type of transformer, the impedance voltage and capacity is basically inversely proportional to the large transformer impedance voltage is smaller than the small transformer impedance voltage. Parallel operation after the load distribution is basically proportional to the capacity of the transformer. But this ratio is not exactly the same, so even if the same type of transformer, the capacity difference is too large (more than 3 times), it is not allowed to run side by side. If it is different types of transformers, the impedance voltage and capacity is not completely inversely proportional to the capacity. The load distribution is even worse.
Q:i took it out. on one side of the transformer i have a black and a red im hooking those up to a battery on the other side i have five wires 2 red, 2 white, and 1 blue i dont know what these do or how to get current to them. does anyone know how to complete the circuit???
Heck no, there is no way I would take my 4 year old son who LOVES Transformers (no idea why he loves them, he's never even seen the cartoon, just has the toys). I took him to see a PG rated movie Saturday (Up) and regretted it b/c I'm still not sure it was appropriate for his age (he was very scared many times throughout the movie and put his head under my arm to hide).
Q:Transformer total circuit breaker rated current 380v, rated current 1000a, the rated capacity and output power how to calculate, I did not learn more points
KVA is apparent power, kW is active power. inspecting power: S = 1.732UI = 1.732 x 0.38 x 1000 ≈ 658 (kVA) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × 0.8 ≈ 526 (kW) AC power, power divided into three kinds of power, active power P, reactive power Q and apparent power S, at any time these three power always exist at the same time. ????? The cosine of the phase difference (Φ) between the voltage and the current is called the power factor, denoted by the symbol cosΦ, where the power factor is the ratio of the active power to the apparent power, that is, cosΦ = P / S ????? Three power and power factors cosΦ is a right-angle power triangular relationship: two right-angled edges are active power P, reactive power Q, and oblique edge is apparent power S. ????? S? = P? + Q? S = √ (P? + Q?) ????? Apparent power S = 1.732UI ????? Active power P = 1.732UIcosΦ ????? Reactive power Q = 1.732UIsinΦ ?? ????? DC = P = UI = U? / R = I?R
