Performance characteristics

1.The features of this product are high efficiency and low loss.It can save a lot of operation cost,and the social benefits are very significant.

2.The iron cores are made of the imported high-conduction magnetism,cold-roll,and grain-oriented silicon-steel sheets.The iron cores and windings adopt the vacuum drying and vacuum oil-filling processes,which make the internal moisture down to the very low level.

3.The conservator is hermetically sealed,which make the internal running oil to insolate with oxygen and moisture efficiently.

4.The above features guarantee the transformer does not need do replace the oil during the normal operation,greatly decrease the maintenance cost,and prolong the service life.

Q:Rated capacity of three-phase transformer S = √3 * U * I: S is the total capacity of the three phases, is the apparent power, the unit is KVA. The sum of the three phases is equal to the sum of the three single-phase capacities, ie S = 3UI where U is the phase voltage and I is the phase current. If the line voltage line current, then S = √3UI This is because when the winding is triangular connected, the line voltage is equal to the phase voltage, the phase current is equal to 1 / √3 times the line current, 3 / √3 = Similarly, when the star is connected, the phase current is equal to the line current, the phase voltage is equal to 1 / √3 times the line voltage, the same 3 / √3 =

Q:Hi, I need a High Frequency( example~200khz) High voltage(200 000v) power supply at low microcurrent, I know that a Tesla coil fits the bill very easily . But I need to manually VARY the frequency(say from 100khz to 200khz ) while keeping the High voltage the same? Is this possible, Can some one guide me where I can buy or build this? Can I just for instance connect just a van de graaf or a rectified Tesla Coil to a function generator? If not what do I need to do to achieve what I want? I have been searching without help so your support is much appreciatedThanks: The Tesla coil needs to operate at the same resonant frequency on both the primary and secondary sides of the loosely coupled transformer. The resonant frequency is set by the inductance and capacitance of each side. The problem is there are no high voltage solid state capacitors (varactor diodes like you see in r.f. receivers that adjust the tank circuit frequency) on the primary side, and no way to adjust the top hat toroid capacitor on the secondary side (unless maybe it was a mylar covered balloon with vacuum deposited aluminum that could be remotely inflated or deflated). So you are stuck with whatever high voltage capacitor and toroid top hat you have on hand, and the inductance of the coils you wind that ends up being the resonant frequency. Even then it takes a lot of fiddling to get both in tune to give the maximum voltage output. The input frequency to the primary coil (the 555 circuit used in the step up with the flyback transformer- its frequency was chosen solely due to the flyback's frequency design) has little to do with the primary's resonant frequency; again that is set by the capacitor used and the size and number of turns of the primary coil.

Q:A 8000kva transformer can bring the maximum load: A good transformer can work at full capacity. But affect the service life. It is best to 80% of the power of this transformer is the best.

Q:Altium designer DXP transformer in the same name how to change?: The same name is a painting of about 2-3mil radius of the solid circle, can not directly change, must be copied from the source file to the schematic library file can be changed, that is, to re-create schematic symbols.

Q:I have a Whirlwind microphone splitter box with a direct out and a transformer isolated output. What's the reason for the transformer isolated output?: A mic splitter is used when you have to feed two different mixers (for example, a front of house and monitor mixer). The main reason for the transformer isolation is to prevent ground loops. You've heard 'emthat 60Hz hum you get when audio equipment is connected incorrectly. The transformer breaks the direct connection between the mic and the second mixer. The mic will get it's ground through the direct connection to the first console. Another benefit is that loading is reduced on the mic. This preserves the frequency response. Also, the transformer isolation prevents any weirdness if phantom power happens to be turned on at both mixers. Back to ground loops now. If instead of using an iso box, you simply Y'd the connections all together, here's what could happen. With that scenario, you've now tied the grounds of two different mixes together. Now, each mixer had it's own path to ground through the 3rd pin of the AC power cable. Now, they have 2 pathsthrough the AC power cable and through the shield of the mic cable and back through the other console. When you get a loop like that, current flows and causes hum, possible shocks, all kinds of nasty things. That's why in audio the 1st commandment is Thou shall have one and only one path to ground. One final pointalways use the direct output of the iso box first. Otherwise, your mic isn't grounded. Greetings from Austin, TX Ken

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:I need to find a transformer that will convert 480 input to 240 output for a motor controller. Where can I get this type of transformer? I've only been able to find 120/240 transformers.Thanks.: you're looking for a step down transformer. as for where to find them, i'm not sure. try ordering online (OKorder or some of those electronic store) or Radioshack/the Source by Circuit city.

Q:I enjoyed both of these titles' first games very much. I am a big Transformers fan but I also love the first person shooting action Borderlands has to offer. I only have enough money to pre-order one and get it on its release date but I can't decide. What are your opinions? What will I get better gameplay value out of? Which do you think has a better pre-order bonus? I welcome any and all opinions and answers!: Hi, okorder

Q:Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household? Thanks-jj: This Site Might Help You. RE: is pole mounted transformer emf harmful? Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it.

Q:Do you think transformers is a good movie?Whos your favourite team autobots or decepticons?Whos your favourite transformer?And whats the best scene in the film?: It was pretty cool, nice trip down memory lane. Autobots and Bumble Bee and the bit when he blasts who's gonna drive you home cheesy and funny!!!
