Product Description:



Furnace transformer of HS9,HSZ9,HSP9 series


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:House near a polyphase transformer?
Poly-phase transformers which are merely 3-phase transformers don't really cause anymore interference than any other transformer. If the thing was up against your wall, then maybe it would mess with radio or cell phone communications, but really your main interference concerns would be if you were near high voltage transmission lines. Why not ask the previous owners or neighbors in the area if this transformer has interfered with their electronics.I doubt it.
Q:Two Transformers Parallel Operation
The total capacity of the two transformers in parallel is not a simple addition of the capacity of the two transformers. Even if the rated capacity of the two transformers is exactly the same, the impedance of the two transformers can not be exactly the same due to the existence of design / manufacturing errors. Based on the principle of the parallel circuit, the transformer with a small impedance will share a larger current, A transformer has been overloaded and another transformer is not yet fully loaded. Can be based on the measured value of two transformer impedance (on the nameplate). Calculate the transformer with a small impedance to reach full load, the load of another transformer, the sum of the two is the total capacity of the two transformers in parallel. In fact, the transformer capacity selection is usually about 25% greater than the actual load, so the reality is usually not a full load, while the other has been a serious overload situation.
Q:Do transformers (110V-220V) drain much power?
Mike, here is an easy approximation with no tech talk you can perform. Leave the power on to the transformer but remove the load and let temp stabilize. Feel how hot or better yet put a thermometer on the transformer. This heat is a direct result of transformer losses while idle. Next remove power to the transformer and devise a metal box to put a lamp in to heat the transformer overnight. Try to capture all of the lamp heat into the transformer to heat the core. Try this using various lamp wattages. When the temperature rise from the lamp equals the temperature rise from running the transformer idle the lamp wattage will be a close estimate of the power wasted by the transformer at idle. A wattmeter will also tell you this but they can be expensive. A good meter and an oscilloscope will be necessary otherwise but that is another story. Heat is always wasted energy the more produced the more it costs you to run. Regarding if you should let it run the answer is sure why not. You probably already have transformers running in your house all of the time. Door bell, Furnace, hot water tank, may be a few.
Q:20) A step-up transformer is connected to a generator that is delivering131 V and 96 A. The?
Vp Voltage Primary Vs Voltage Secondary Np Number of Turns Primary etc The values you have given are primary, why? Because its Generator Transformer (GCSE stuff) Equation : Vp/Vs Np/Ns 131 / Vs 1 / 859 Vs 112529 V (large cause its a step UP transformer) 2). This equation is similar just slight different order: Vp / Vs Is / Ip (Hence you can rearrange this for power but not needed here) 131 / 112529 Is / 96 Is 0.11 A (2dp) Yet again you'd expect it to be small, because your transforming your voltage upwards to reduce your current (which of course creates less heat so less heat energy lost etc)
Q:Transformer and the middle of what is the difference
In the week is the IF transformer or inductance coil, is a fixed resonant circuit with a transformer, the resonant circuit can be fine-tuning within a certain range, so that access to the circuit can achieve a stable resonant frequency.
Q:Flyback transformer usage?
A 'flyback' transformer won't do anything but blow the breaker if you plug it into the wall. They're designed to run at 15,750 Hz. and yes, they do couple a 'sawtooth' waveform out to the horizontal deflection coils of the 'yoke' around the base of the CRT which deflect the electron beam to produce an image. If you want some -great- sparks, go out on the 'net and look ou plans for a 'Tesla Coil'. I've built a couple of those that would draw an arc several inches long. And since they're very low-current (on the secondary side) they're quite safe to play with. HTH, Doug
Q:Step Down Voltage Transformer / Regulator?
a regulator
Q:Can someone give me a pinout for an Audio Transformer?
I guess you know that if you use a transformer with two separate windings, they are electrically isolated. The audio transformer is used to match a 4 ohms load such as a speaker, to an amplifier which does well with say, a 100 ohms load. In that case, you use a step down transformer with ratio N 5. Note that N^2 is 25 and 100 ohms divided by 4 ohm is 25. The voltage is brought down by a factor of 5 while the current the transformer can deliver increases to five times that the amplifier can deliver. So it is used as an impedance matching device. Just as a 23VA transformer operate at 230V takes 100mA and delivers about 1 amp at 23V if it is a step down transformer of 10:1. the secondary voltage is 23V.
Q:Power Transformer help!?
If you assume no losses, the power remains constant. If the voltage is stepped up, the current is stepped down in the same ratio. The input current will depend on the output current drawn by the load. With a transformer stepping up 1:4, 25 volts becomes 100 volts and the current is determined by the resistance of the load. If you assume it to be 100 ohms, for example, the current will be 1 amp. This is reflected as a current of 4 amps at the input.
Q:Proteus transformer how to adjust the parameters, the 220V into 14V output.
2, in the Proteus simulation diagram, double-click the transformer symbol, open the transformer parameter settings dialog box, which                 Primary Inductance 1H (set: can be fixed)                 Secondary Inductance 0.00406H (set by press)
