Product Description:

Product structure:
1.It's with small volume and compact conformation. It covers just about 1/3 to 1/5 of the usual European-style substations, which have same capacity with it.
2.It's full-sealed and all-insulated. And it uses the S11-type transformer, which has low-wastage, low-voice and strong ability of overloading. adorpts devides box type.this type protects the transformer from polluting by the oil which is in box.

4.high voltage side adopts double fuses all range protective makes cost less . can be used as ring net ,and also as end,cable lug can be insected and extracted when it is 200A loading current. body is honeycomb double sandwich composite panels type,has  thermal insulating and heat release performance.this technical is our patent.

Q:Transformers. Optimus Prime?
Q:What type of transformer do I need?
Assuming you wire the bulbs in parallel. You need a similar transformer (6v secondary) but one that is rated at 240 watts (or a bit more), 40 amps. Note that the current will be 40 amps and will need quite a heavy wire, #4 or 5. You could also put the bulbs in series, and would need a 48 volt secondary, still at 240 watts. You would have problems of any series string, if one bulb goes out, they all go out. You can also use parallel series combos, 3 pairs, or 2 strings of 3 each as a compromise. edit. Later thought of another alternative that may help. Get a transformer with a 12vCT 240W secondary. Wire like you would 2 phase house wiring, 3 bulbs to each outside terminal, and all 6 to the CT. This means the wire only has to handle 20 amps and can be smaller, and you will not have the series string problem. 12VCT transformers are fairly common. Or if you can find it, and the wiring is still a problem, get a transformer with 2 secondaries each of 12VCT at 10 amps.
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:10KV distribution transformer how to calculate the tap voltage
10kV distribution transformer tap voltage can be Ue ± Ue X% (X is the percentage of each range of adjustment). General distribution transformer tap adjustment range of Ue ± 2 × 2.5%; tap for 1 - 5, the tap voltage is calculated as follows: 1 ----- 10+ (10 x (2 x 2.5%)) = 10.5 kV 2 ----- = 10 + (10 x 2.5%) = 10.25 kV 3 ----- 10kV rated voltage, 4 ----- = 10- (10 x 2.5%) = 9.75 kV 5 ------ 10- (10 x (2 x 2.5%)) = 9.5 kV Transformer tap on the high side, according to the needs of the low side to adjust the high pressure side of the tap position. If the low voltage side of the low pressure should be raised to 4 or 5, and vice versa to 2 or 1 up. Because the adjustment tap is used to change the transformer ratio. In the case of a transformer with a rated voltage of 10 / 0.4kV, its change ratio K = U1 / U2 = 10 / 0.4 = 25; when the secondary voltage is low, if the split is set to 4, the position K4 = U1 / U2 = 9.75 / 0.4 = 24.375, the primary voltage is still 10kV secondary voltage = 10 / 24.375 = 410V. Increased secondary voltage. In fact the adjustment of the split is adjusted by the number of turns of the coil, the change in the ratio and the number of turns of the secondary coil is constant. To reduce the secondary voltage, increase the number of turns of the coil.
Q:KW how to know how much transformer?
Know the number of KW, how to calculate how much transformer is needed. In general, our calculation is based on the nature of the equipment, the production process, the development prospects of the production enterprises to analyze the size of the transformer, some companies, how many kilowatts to choose the number of KVA, and some enterprises have all the equipment must boot Run, then, on the choice of a little bigger, the machinery industry enterprises, generally in accordance with the installed capacity of 4-5 fold to select the transformer capacity. For reference only.
Q:Switching Transformer, Alternative to MPPT Charge Controller? (wind+solar)?
Homemade okorder
Q:What is the difference between AC transformers and DC transformers?
DC transformer to change the voltage first to use the electronic components of the DC current into alternating current, and then transform the voltage with the transformer. This device is called the inverter.
Q:why cant a transformer work in dc?
Transformers do not work with direct current (DC), where the current constantly flows in the same direction.
Q:How would I wire a microwave transformer to create arcs?
here you go
Q:What is the meaning of the transformer without excitation?
General power transformers are equipped with tap-changer, can be carried out in a small range of voltage regulation to meet the grid voltage fluctuations, as far as possible to the transformer output side of the voltage stability. There are two ways: 1, on-load regulation: it can be in the transformer with load, automatic or manual tap position switch. Because the switch is completed in an instant, so it will not affect the normal operation, that is, once, the second side are not power failure can be carried out under the circumstances. 2, no excitation voltage regulator (sometimes mistakenly said no load voltage regulator): is to be in the primary side and the secondary side are power outages, put the isolation switch to open the case, to ensure that the transformer in the absence of electricity, adjust the tap position , The regulator. 3, in the past, it is possible from the English No Load (no load) or On Load (contained) translated over, said to be no load regulator. This is not accurate, it is easy to be misinterpreted as: the transformer can be in the absence of load (current) when the regulator, without the need to control whether the power side. This is very dangerous, no excitation voltage regulator, it is very accurate, to the transformer side, the secondary side are power, in the absence of any excitation circumstances, to operate. 4, therefore, our professionals must change No - Load to Off - Eirecuit - Tap - Changing.
