1. Product introduction

The furnacetransformer is a transformer for power supply to furnace electricalsource. It is used to reducea voltage from a high voltage to an operational voltage needed by furnace.
Accordingto many different types of furnaces,there are many varieties of furnace transformer to fit it.At present, the furnace transformers produced by ourcompany are: electric arc furnace transformerused for steel-making furnace (including on-load and no-loadhigh voltage and enclosing reactortype); the furnace transformers (single - -phase, three-phase on-load and no-load voltage regulating) usedfor smelting various ferroalloy, silicon compounds, mineralssuch as calcium carbide, are all the low-loss energy-saving products.

Q: A 120 kVA, 7000/277 V (What does this rating mean) distribution transformer has the following resistances and reactances: Rp 5.5 ohms Xp 6.5 ohms Rs 0.007 ohms Xs 0.008 ohms Rc 55 kohms Xm 15 kohms The excitation branch impedance are given referred to the low voltage side of the transformer: a) What's the equivalent circuit of the transformer referred to the low voltage side b) What's the the per unit equivalent circuit c) Assume that this is supplying rated load at 277V and 0.89 lagging power factor, What is the transformer input: 120 kVA, 7000/277 V (What does this rating mean) Primary voltage rating: 7000 V, secondary voltage rating: 277 V, rated load: 120 kVA It is unclear whether this is a single-phase or three-phase transformer. You probably need to assume it is single-phase. The equivalent circuit of a 3-phase transformer is analyzed as one of three single-phase transformers that could be connected to make the equivalent Y-Y three-phase transformer. The secondary voltage, 277 V, is the line to neutral voltage for a 480 V, wye distribution system. That is a USA standard system voltage. The primary would be 12,124 V L-L, 7000 V L-N. That would a reasonable primary distribution system voltage. Referring the circuit to the low side means changing the primary component values to the equivalent secondary values and moving the ideal transformer to the primary side of the circuit as shown below. To change the primary impedance values, multiply by (Sec V/Pri V)^2.

Q: i have a transformer and i dont know anything about it. can someone help me with it.ps: i dont know how many turn the transformer have. dont the voltage either: _IF_ the toroid replaced into under pressure out to function off 50-60 Hz, and you are able to grant a prevalent transformer which will grant a similar AC output (the two voltage and modern means), then it is going to artwork. even nonetheless, if that toroid is a factor of a switching ability grant, then a prevalent transformer won't artwork. So the question maintains to be, is there an number of digital factors under pressure out around this toroid? if so, then you somewhat could desire to acquire a sparkling toroid, or in case you have a large style of time on your palms, rewire the prevailing one. (diploma and eliminate latest twine, noting their association and counting the turns as you circulate). If the toroid is meant to artwork on 50-60 Hz, then you somewhat ought to have some situation getting a prevalent transformer to greater healthy interior the lamp, yet i think you are able to make it exterior and placed it into this is very own container, equivalent to a modular grant.

Q: What are the malfunctions and abnormal operation of the transformer? What is the difference between them and the line?: Transformer failure: can be divided into the tank failure and tank failure. Fuel tank failure: a short circuit between the windings, short-circuit between the turns, direct grounding system side winding short circuit. Outside the tank failure: There is a short circuit between the casing and the lead wire and the ground short circuit (direct grounding system side). Transformer is not working properly: there are external faults caused by over-current, overload, oil level and due to over-voltage or frequency caused by over-excitation and so on. Line fault: phase short circuit (including three-phase short circuit, two-phase short circuit), two-phase ground short circuit, single-phase ground short circuit, transmission line disconnection.

Q: 1.) What is the function of a transformer?a.) It is a device that can change the voltage of an AC supply.b.) It can change a low voltage supply into a high voltage supply or vice versa.c.) It is a device used mainly to change AC into DC.d.) A and B are correct.2.) What is the function of a transformer at a power station?a.) To convert DC into ACb.) To produce very high voltagesc.) To produce the currents in the power linesd.) None of the above.: Sorry but I don't know about this

Q: 1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,: If the enter is 24 volts, the output would be 440 volts, yet do no longer try this via fact which you will likely dissipate the transformer. you could word any voltage below the rated enter and the output would be proportionately decrease. in case you word 6 volts, you will get a hundred and ten volts out. i wish this enables.

Q: I have a few questions about flyback transformers: How high of a frequency can they go without alot of losses?Can I get a negative High voltage by reversing the polarity of the primary?How can I make the flyback safe from the capacitive charge that it holds?: The flyback transformers used in TV's work at about 15000 hertz (the horizontal scan frequency). The transformers used in switching power supplies are smaller and work at a higher frequency, but they normally have a low voltage output. The transformer produces a high AC voltage, and a rectifier diode changes it to DC. Reversing the diode gives you a negative output. The picture tube provides capacitance to smooth out the voltage and holds the voltage for a while after the power is turned off. If you don't use a picture tube, you might need a capacitor if you want a steady output voltage. Shorting out the capacitor will remove the voltage.

Q: How the transformer is transformer: The role of the core is to strengthen the magnetic coupling between the two coils. In order to reduce the iron in the eddy current and hysteresis loss, the core from the painted silicon steel sheet laminated; between the two coils there is no electrical connection, the coil by the insulated copper wire (or aluminum) A coil connected to the AC power supply is called the primary coil (or the original coil), and the other coil is called the secondary coil (or secondary coil). The actual transformer is very complicated, inevitably there is copper loss (coil resistance heating), iron loss (core fever) and magnetic flux leakage (by air closed magnetic induction line), etc., in order to simplify the discussion here only describes the ideal transformer. The ideal transformer is set up under the condition that the leakage flux is ignored and the resistance of the original and secondary coils is ignored. The loss of the core is ignored and the no-load current is ignored (the current in the secondary coil turns the original coil). For example, when the power transformer is running at full load (the secondary coil output rated power) is close to the ideal transformer situation.

Q: I have a small question concerning flyback transformers. I have run into some confusing problems when i tried testing the flyback using the High voltage power supply project: You might find whether your transformer is broken with an ohmmeter between the ultor cap and a pin by trying each with the meter set to a high ohms range, with (I think) the black meter lead connected to the ultor. If you don't see a result 1st. time around, try swapping the meter leads. If you get a result, try the 24V test there. If you don't, and using his method also fails, I think you have a dud. So far as the 9V test, I think that has a fatal flaw. A digital multimeter, or usually also an analogue one, cannot respond fast enough to a single pulse. A digital meter only samples at a certain rate, and if the voltage does not align with the sampling, you see nothing. Even if it does, I think you would only see an instantaneous reading before next sample sees nothing. Apart from that, the voltage spike will be well over 200V! The object is to sort out input direction in the primary. I would suggest you sort out the primary connections, and build the circuit. I have not looked at it, but I think if you fire it up, you will either have + HV coming from the ultor cap, or nothing. If nothing, reverse the primary. DON'T TEST IT WITH YOUR FINGERS!!!
