Q:What are the specifications of the transformer capacity?
Select the transformer capacity, to the existing load as the basis, appropriate consideration of load development, select the transformer capacity can be determined in accordance with the 5-year power development plan. When 5 years of power development is clear, little change and then the load is not less than 30% of the transformer capacity:     SN = KS ΣPH / (cosφ η)     Where: SN - box change in 5 years required configuration capacity, kVA ΣPH - 5 years old with financial calculations, kW KS - at the same time, generally 0.7 to 0.8 Cosφ - power factor, generally 0.8 ~ 0.85 Η - transformer efficiency, generally 0.8 ~ 0.9     According to the formula generally KS = 0.75, cosφ = 0.8, η = 0.8     SN = 0.75ΣPH / (0.8 × 0.8) = 1.17ΣPH     Example: a district in accordance with 50W / m2 design, then     PH = 50 × 19200 = 960kW     SN = 1.17 x 960 = 1123 kW     So the district selected three 400kVA transformer.
Q:how big are the transformers?
i think of Spiderman 3 would be greater valuable and earn greater money. the subject i'm able to be certain happening is that Transformers will circulate the way of Inspector gadget and not resemble its source cloth adequate to garner a fabulous following. I hear you will honestly see Optimus Primes mouth, and megatron isn't a gun anymore Spiderman has its divergences from the comedian, are not getting me incorrect i think of he would desire to have had webshooters, not organic and organic webs. regardless of the undeniable fact that it nevertheless maintains to be actual to the Spiderman tale. i don't think of the studios will difficulty sticking to what transformers became approximately, they are going to greater probably advance up the particular outcomes and merchandise the hell out of it. With large power comes large accountability. Megatron would desire to be stopped, no count the fee Dun dun dun dun, you acquire the touch. you acquire the flexibility!!!!!!!!!!! Yeah!!!
Q:Transformers 2 question.?
The movie is called Transformers: Revenge of the Fallen. It comes out June 26th. Decepticon forces return to Earth on a mission to take Sam Witwicky prisoner, after the young hero learns the truth about the ancient origins of the Transformers. Joining the mission to protect humankind is Optimus Prime, who forms an alliance with international armies for a second epic battle.
Q:Transformers Revenge of the Fallen DS help?
Well, it sort-of has a create a bot feature, but not quite. In the beginning of the game, when you get your transformer as a protoform and once you get to do actual missions, you get to choose out of only three types of vehicles: A light but fast car, an all evened out sports car, or a heavy armoured tank (sort of like another game). However, you can only chose one because you are stuck with that form for the rest of the game. HOWEVER,with energon you pick up fighting other enemies and scanning computers or machines, you can customize stats (attack, agility, defence, ranged attacks, health, and regeneration of health) an customize your robot with different weapons. The game is not a wander-around game like its predecessor, but challenges are available. I guess after you beat the game or when going throughout levels, you play as transformers such as Starscream (beginning of Decepticons) or Optimus Prime (beginning of Autobots).
Q:rheostat on DC transformer?
Transformers do not rectify and filter the output. It's AC in and AC out. A transformer either steps up the voltage or steps it down, depending upon direction. A transformer is only the first step in converting 110vac to a DC voltage. After the transformer has stepped down the 110v to 30v (AC!), it needs to be rectified into pulsating DC. Using 2 diodes (half wave rectifier), the DC will be 21v (still pulsating an unreliable for your use). If you use 4 diodes (full wave bridge), the resultant pulsating DC will be 42v. Now you need to filter it using capacitors so that it's a steady DC. You COULD use a potentiometer (rheostat) in a voltage divider network to dial down the voltage that you want to use, but fluctuations in the 110v will still be transmitted to the finished DC. So you also want to use a voltage regulator chip. That way, you get a steady, filtered, reliable DC voltage.
Q:What is a transformer paused?
5. Users who charge the basic electricity charges according to the maximum demand shall apply for the suspension of all the capacity (including high-voltage motors that do not pass the receiving transformers) and comply with the relevant provisions of Clauses 1 to 4 of this Regulation.
Transformers was a AWESOME MOVIE!, but it really annoys me when people tell me that the only thing good was the special affects. It takes really talented actors to play only on green screen, and the acting was very funny AND dramatic. My favorite are the Deceptions, just cause they have those really small things that can turn into stuff. I can't remember what they were though. My favorite transformer is Bubblebee, because it can talk through the radio which when I was kid was what I wished I could do. I my favorite scene probably is when the Autobots are causing mayhem while Sam is trying to find the glasses. I love it that Mojo peed on that one.
Q:Three-phase transformer how four ways to connect it?
If the three-phase transformer has four windings can not have four kinds of wiring way?
Q:Physics Help Solving transformer problems?
1:150 implies a Voltage Step Up transformer. Hence the secondary voltage is 4500 x 150 675000 V 675 KV. 45 W at 4500 V means Ipri 45 / 4500 1/100 A or 10 mA. Secondary current 10 mA / 150 66.6 uA If they meant a 150:1 transformer the answers would be:- Secondary Voltage 4500 / 150 30 V. Primary Current 45 / 4500 1/100 A or 10 mA AGAIN; Secondary Current 10 mA x 150 1.5 A.
Q:Transformer insulation level L175 AC35 / 5 What does it mean
The voltage withstand voltage is 480kV, the power frequency withstand voltage is 200kV, the middle voltage side of the neutral point of the lightning impulse withstand voltage is 250kV, power frequency withstand voltage is 95kV; low side of the terminal side of the lightning Impact withstand voltage is 75kV, power frequency withstand voltage is 35kV; 3, "LI 75 AC 35" means that the 10kV transformer high voltage winding lead side of the lightning impulse withstand voltage is 75kV, power frequency withstand voltage is 35kV.
