Product Description:

Scope of application

The transformers are applicable to AC50-60HZ circuits,it could be widely used on control power supply for mechanical equipments such an bridge crane,ship,wind power generation,photovoltaic power generation,testing machines,local lighting,signal lamps and others.


It has charachteristics of excellent performance,reliable operation,low energy consumption,small volume,safe wiring and wide application,and as it can work for a long term under rated load,it is an ideal variable voltage power supply.

Q:How long will it take to fix a transformer?
As long as the power company has transformers and all other damaged equipment in stock, they should be able to have everything repaired soon. It is hard for me to predict how long because there may be other things involved, not just the transformer. Is this transformer on a platform, or pad-mount? Could it actually be the feeder wires that caught fire in addition to or instead of the transformer? Is it possible that the fire damaged feeder wires from the transformer to the stores? If so, the store owner(s) may be responsible for making those repairs. The best way to get an answer as to how long this repair will take is to ask your store manager or owner, for the power company should be willing to give time estimates to them.
Q:AC-DC transformer?
The transformer only responds to AC voltage and is basically a short to DC voltage. In order to achieve your desired result, you'll need to configure a voltage multiplier circuit and it's much better to keep your AC input, installing capacitors in line with 110 Vac input and in parallel across your resistive load. Performing this feat with 6-12Vdc would involve switching circuits across capacitor banks and little or no available current.
Q:630KVA transformer can use the maximum number of power appliances
General transformer power factor is 0.85 or so 630X0.85 = 535.5KW, you should be installed capacity of 590KW, if it is not necessarily open at the same time, there is no problem. On the contrary, you can also increase the capacitor to improve the power factor to run .300KW If not more than 150 meters, then available 3X120 +50 copper cable, the distance from the increase in the line by.
Q:How the transformers arcs work and end?
G1 never really ended it was a cliff hanger that they wanted to expand into a series called Head Masters (only aired in japan) where Armada, Energon, and Cyberton (aka the Unicron trilogy) all played into each other Armada ending with the aurobots returning to cybertron, Energon the death of Unicron, and Cybertron the closing of the black hole Unicrons death created.
Q:Inverter Transformer Question?
The equation V 4.44fNaB determines what is required for a transformer to avoid saturation. V is the voltage, f is the frequency, N is the number of turns of wire in the winding, a is the area of the core, and B is the peak magnetic flux density. The transformer has presumably been designed so that the peak flux density is as high as it can be without saturating the core. For an existing transformer, V/f a constant. If you increase f, you can increase V so that V/f remains constant. However, the hysteresis losses increase in proportion to the frequency increase and the eddy current losses increase in proportion to frequency squared. In addition, skin effect will increase the copper losses at higher frequencies. Reducing the copper losses by reducing the current would compensate for the skin effect. Reducing the copper losses would tend to compensate for the increased iron losses, but it is hard to say how much a cooler coil will compensate for a hotter core.
Q:What does an isolated transformer output on a microphone splitter do?
This Site Might Help You. RE: What does an isolated transformer output on a microphone splitter do? 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?
Q:how to maintain dry transformer winding?
there is no oil for transformers. they are kept dry by all the heat they generate. it cooks the moisture out. if there is a specific reason you are worried, please do tell. is it going to be stored or go unused for a while? is there a lot of moisture in the area of operation? if not, i would not worry about it. it sounds as if it might be near the end of its life cycle as is. on the bright side transformers dont just burn out. there must be a reason for the failure. moisture is not too bad, but water is.
Q:Step up transformers?
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:about power transformer?
1, less susceptible to parasitic thermocouples and pressure drop along the wire resistance and temperature drift of the transmission line can be very inexpensive twisted pair wire finer; 2, in the current source output resistance is large enough, the magnetic field sensor coupled to the wire the voltage loop will not have a significant impact, because the interference caused by the current is very small, usually using twisted pair can reduce the interference resistance; 3, the capacitive resistance of the receiver causes interference on the error, both for 4 ~ 20mA wire loop, the receiver resistance is usually 250 (sample Uout 1 ~ 5V) that resistance small enough to produce significant errors, therefore, can allow the cable length longer than the voltage telemetry system further; 4, each single display device or recording device can be read in the wire lengths between the different channels for access, not caused by wire length ranging between accuracy; 5, 4mA to zero level, to determine the open circuit or sensor is damaged (0mA state) is very convenient. 6, in the easy addition of two-line outlet surge and lightning protection devices, is conducive to safe mine explosion.
Q:Should I get Transformers: Fall of Cybertron or Just Cause 2?
^^^ I disagree, Just cause 2 is just a bunch of flying around with your unrealistic/infinate parachute while shooting people. (Not that transformers is realistic) but still. Just cause 2 will bore you to tears i kid you not.
