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:I am going to see Transformers 3 today with some friends. Can someone give a detailed summary of what happens in Transformers 1 and 2 because i haven't seen them. Thanks to whoever helps.
- here okorder
- Q:i wish to construct a transformer with 220/120v,60hz,5watt,plz help me
- Transformer is a thing which can reduce or increase voltage. In your question, You want to make such a transformer which can reduce the voltage is called a step down transformer. In transformer there are two coils. One is Primary and the rest of them is Second nary coil. Primary Coil is connected with input(220v) and Second nary with output(120v).To get 120v in output the transformation ratio should be 220:120 means 11:6.
- Q:Who knows the density of the transformer oil is how much?
- 25 # transformer oil: 895kg / m3 877.6kg / m3 45 # transformer oil: 895kg / m3 879.0kg / m3
- Q:I need to make a small transformer (that uses AC obviously) that would boost an input voltage of 20-30 millivolts at 1.5 mA to a output voltage of 1 volt (with a current that would obviously be very small) How must I design and build the transformer to accomplish this? Thank you.
- Transformers follow Ohm's Law and multiply or divide voltages based on the number of turns making each coil. You need only ensure your two coils have the appropriate number of windings. As for actual numbers for the windings, 1.5mA is an absolutely tiny amount of current, so you have considerable flexibility in this. If you are looking to build a transformer, you should look up the information on what you're planning to use for a core, to be able to calculate the voltage across the secondary coil.
- Q:How long does it take to restart the transformer?
- (4) power failure operation, the first load side of the switch, after the power side of the switch (multi-side power from low to high stop); first pull the transformer side of the knife, after pulling the bus side of the switch. Power supply operation is reversed. (5) into the backup transformer, the device should be based on the actual location and instructions to determine the load has been taken in order to make the operation of the transformer power failure. Diagonal and 3/2 wires on the transformer, although the transformer has been out of power, but the transformer's heavy gas and differential protection action can still cause its ring side of the switch trip. Should be based on the actual situation and the site of the gas protection to change the signal location or retreat gas out. (6) station transformer does not allow long-term side by side. Can be used to cut low-pressure low-pressure side of the cutting machine, with high-pressure knife cut off the station with a transformer.
- Q:does anyone know if there will be a next transformers?? there were rumors that there will be a 2nd in 2009 but with the same actors/actresses????I CANT WAIT THAT LONG :-(
- Yes , if you saw the credits the 3rd scene it shows starscream going to space.
- Q:27. Two transformer A and B with identical ratings, are to be designed with fux densities of 1.2 and 1.4 wb/m2 respectively. The weight of transformer A per KVA is(a) More than that of transformer B(b) Less than that of transformer B(c) Equal to that of transformer B(d) None28. Transformer action requires which type of flux?(a) Pulsating magnetic flux(b) Constant(c) Increasing(d) Alternating electric flux29. In what capacity transformer natural oil cooling with tubes is used(a) 3000 KVA(c) 500 KVA(b) 30 KVA(d) 750 KVA30. In full rating of transformer is 90 KW at a pf of 0.9, then its KVA rating is(a) 100(c) 90(b) 150(d) 80
- 27. (a) More than that of transformer B 28. (a) Pulsating magnetic flux 29. I do not think there is such a limitation on ONAN transformers. 30. (a) 100
- Q:i want what does a transformer exactly do and not how it works
- A transformer is used to increase or decrease voltage, but only for alternating current. It won't work with direct current. When a current alternates in a current carrying conductor a magnetic field expands and collapses, changes polarity and expands and collapses again. It then repeats the process for each cycle of the alternating current. If you have another current carrying conductor within this changing magnetic field, then another current is induced into that conductor as a result of the magnetic field cutting the conductor. This is called induction. So an alternating current in one conductor can induce a current in an adjacent conductor. In a transformer we have two coils, the primary and the secondary. If we have twice as many turns in the secondary to the primary we have a step up transformer - it steps up according to the ratio of turns between the two coils. Here the ratio oi 2:1 so the voltage is increased by 2.
- Q:Electrical Machinery, electrical machines, transformers
- A transformer steel core's remanence means that it retains a static magnetic field when power is removed. When power is then reapplied, the residual field will cause a high inrush current until the effect of the remanent magnetism is reduced, usually after a few cycles of the applied alternating current. Overcurrent protection devices such as fuses must be selected to allow this harmless inrush to pass. When a transformer is livened, the magnetizing inrush currents are estimated as multiples of the transformer's nameplate kVA. Time Current (sec) - (amps) 0.01 -- 25x 0.10 -- 12x In addition, during the normal life of a transformer you can expect hot-load and cold-load pick-up events. These are estimated as Time Current 1.00 -- 6x 10.0 -- 3x 100. -- 2x You must select transformer fusing that will not be damaged by these events. Drop me an e-mail for a more detailed explanation.
