1.Product Feature The sz9 on-load tap-changer power transformer is widely applies to urban and rural electric network construetion. The iron core is in ladder shape and changes the traditional piling way of iron core as well as the inner distribution of magnetic way. It also decrease the no-load consurmption, no-load current consurmption and noise pollution all by 20%. The new product applies CAD tool and marked with advanced design, reasonable structure, high quality material. It accords with GB1094-1996 and GB/T64511999. 2.Technical Specification

- Q: For my proposed new aluminium extrusion factory I ve the load of 250 kw heater and 670 HP of motors.Whats the kva rating of the transformer I should go for?Pls advice.
- The total load is around 750kW but allowing for low power factor on the motors I would suggest you make it 1000kVA' get that or the next size up transformer off the shelf. Fit automatic power factor correction to reduce the load and save money.
- Q: What is the use of the lower part of the transformer made of rail?
- This approach facilitates the handling and installation of the transformer, but due to the large and larger transformers, the use of wheels is already less. Transformer The lower part of the box has two structures: (1) Set the wheels, which requires the installation of the track on the basis of the transformer, and then the wheels fixed on the I-beam track, this way to facilitate the maintenance and installation of the transformer handling, but because of the large and larger transformers, the use of wheels Has been less; (2) set I-beam or channel as a load-bearing beam. This transformer does not need to set the track, on the basis of the transformer relative to the location of the beam weighing embedded flat steel, the transformer in place after the load-bearing beam fixed fixed on the base embedded parts. Need to move the transformer, the chisel spot welding, with the hoist and other machinery will slowly drag the transformer.
- Q: I have a 120v X 24v step down transformer that is capable of supplying 30 amperes. I need to convert the output to dc to supply a project I am working on. I have a bridge rectifier capable of handling 10 amps continuously, but nothing that could handle the 30 amp output. What would occur if I put the rectifier on the input side (with no filter capacitors) and fed the xfmr the DC voltage with 120hz ripple? I suspect the xfmr wont like the 120hz input and generate excessive heat. Anybody know for sure? The xfmr has a laminated iron core and copper windings.
- You are asking some strange questions. You do not have a very good understanding of transformers. A transformer ONLY works with AC. This is why Tesla argued for AC being supplied to houses. With a simple transformer, the voltage could be increased for less loss on transmission lines and then with a step down transformer, the AC could be brought into homes. Edison, on the other hand, loved DC and wanted all houses to be supplied with DC. Edison, in an attempt to prove Tesla wrong, invented the electric chair to show how dangerous the larger voltages would be. Edison even electrocuted animals in his electric chair to demonstrate the effects of higher voltages. Fortunately, Tesla won the argument, or we would not be able to transmit electricity over high power lines from generators to homes. Now, a rectifier in the strict sense, does not change AC to DC (with ripple) but simply reflects the negative wave to make it positive. Thus adding a DC component and doubling the frequency. The DC component will simply pass through the transformer (no heating) and the higher frequency will work just great with the transformer. In fact, you can make smaller transformers by using higher frequencies. This was a technique that Sony used many years ago to make great amplifiers and Fisher and Paykel use to make better appliances. (Other companies might also, but I am not aware of them.) So, your transformer will only see an input of 60 V AC and step that down to 12 V. Thus, you will not have the 24 v you need. Why don't you get a better bridge??
- Q: A 1:150 transformer has a primary voltage of 4500 V. (a) What is the voltage in the secondary coil? (b) If the transformer consumes 45 W, what are the currents in the primary and secondary coils?
- Secondary voltage is 4500*150 If transformer losses are neglected, and a load is assumed in secondary, the load resistance is E^2/P (4500*150)^2/45. Current in secondary 45/(4500*150). Pri current is 150 times current in secondary.
- Q: i wann no wat type (kind, year, color) each transformer is, plz add the transformers name (i'd like them from BOTH the 1st and 2nd movie) plz and thank u!!!
- I'm sure Wikipedia has the answer.
- Q: Is the secondary current rating of the transformer line current or phase current?
- For star-wiring products, the line current = phase current For triangular wiring products, the rated current refers to the line current (phase to phase current)
- Q: I can't remember the funny scenes from any the Transformers movies, especially 1 and 2.It's driving me nuts.I saw the third one just last week so I remember a couple of funny scenes, but other than that, no luck.If you can, could you please include a link to a video clip of the scene?Thanks so much! (:
- When the car turns into bumblebee and the guy says to the girl its probably japanese
- Q: I hate feeling the need to justify myself, but I've seen a lot of answers telling askers to do their own homework. I'm trying to do so, but can't find any equations in the book relating power to voltage as well as turn number. Is it PviN? I've just seen Pvi, but that wouldn't apply to multiple loops. This is for ideal transformers by the way, so power for the secondary and primary coils is the same right? But are their vi's equal, or their viN's?The primary coil of a transformer has 200 turns and the secondary coil has 800 turns. The power supplied to the primary coil is 400 watts. What is the power generated in the secondary coil if it is terminated by a 20-ohm resistor?
- The turns ratio is 4:1 of the primary. The power supplied to the primary is 400W. So regardless of anything else, in a ideal transformer, 400W is available on the secondary. But voltage will be 4x higher, current 4x smaller, than the voltage and current in the primary. Disregarding all that, if there is 400W of power flowing in the primary, then 400W will be being dissipated in the 20 ohm resistor. Watts in watts out, but secondary load (resistance) controls the wattage. There is no way to tell the output voltage and current, without knowing the input voltage and current. But whatever they are, the product of voltage x current will be 400W, in this instance.
- Q: 1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?
- In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.
- Q: Transformer three-phase imbalance which harm
- 1, when the line is not full-phase operation, the zero sequence current is equivalent to the load current, then the line with its adjacent line zero sequence current may be large, even greater than the zero sequence backup protection settings, if not quickly cut Non-full-phase operation of the line, it may lead to adjacent line malfunction, leap-off; 2, for 220kV and above generator transformer group and machine-side circuit breaker, due to non-full phase operation during a larger negative sequence current, the generator, the transformer may cause a greater damage to the equipment.
