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.
3.it 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 way.it makes cost less .
5.it can be used as ring net ,and also as end,cable lug can be insected and extracted when it is 200A loading current.
6.box body is honeycomb double sandwich composite panels type,has thermal insulating and heat release performance.this technical is our patent.

- Q: i dont get it. at the end of the movie. they did not kill one of the bad guys and he flew off to out of space?? do u think transformers 2 is gonna come out ???
- With or without Bay, they will make a Transformers 2. Actually there are a couple still alive. Barricade never showed up to the final fight. Starscream flew out into space. Maybe to go get more Decepticons. Plus who know what other Decepticons were already on Earth that just didn't show up to the fight.
- Q: How do I determine if a transformer is beyond the normal temp range and is at risk of failure?A 225 kva installed in 1996 is running hot. I removed the cover and using a digital thermal meter read approx 125 degrees F on each winding. 243 degrees F on the top metal (winding support) frame. It's got parallel 750's off the load side and would be an expensive and difficult change.
- The temperatures you measured seem hot but might be acceptable for the type of materials used to insulate the coil inside the transformer. Only the designer of the transformer could tell if it's too hot or not. One rule of thumb : for non industrial electrical devices, the outside temperature of the device should remain at a temperature that lets you touch it without feeling pain. But one thing is sure: high temperature is not good because the transformer will age faster and it's less efficient (and therefore generates more heat). The transformer can overheat for 2 reasons : either your load is above the nominal rating or the transformer is not able to cool down as designed (usually because it's in an enclosure which doesn't let the heat get out). If you are indeed getting 750kva from it, then you are definitely at risk. That's more than 3 times the nominal rating. I would be surprised that it lasted for so long. If you can't reduce the load (best option), try to let more air flow freely around it by removing stuff around it. Last resort try cooling it down by forcing cool air to flow around it with a fan. But this can be tricky because the bottleneck of the heat exchange could be inside the transformer so the outside might get cooler and the inside could remain very hot.
- Q: A transformer has a 100-turn primary coil and 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary os connected to an electrical devic with a resistance of 1000 ohms.what will the voltage output of the secondary be?what current flows in the secondary circuit?what is the power in the seconday coil?what is the power in the primary coil ?what is the current drawn by the primary coil?
- If the secondary has 10 times as many turns, it will multiply the voltage by 10 times. 120 VAC x 10 1200 VAC Use Ohm's law, EIR for the current. Voltage Current times Resistance, Volts Amps x Ohms 1200 I x 1000 I 1.2 Amps Power in Watts E x R (Volts x Amps) 1200 V x 1.2 A 1440 Watts For a 100% efficient transformer, the input power matches the output power. In real life, a bit more power goes in than comes out. That's why the transformer gets warm. For this problem, with a perfect transformer, the input power will be 1440 Watts. That makes the input current 12 Amps. What they want you to see in this exercise is that the transformer, because it has a 1:10 ratio in the windings, is that the secondary will have 10x the voltage and 1/10th the current. The primary will have 1/10th the voltage and 10x the current. And they want to make sure you understand the power in matches the power out.
- Q: Design a control circuit to step-up/step-down the voltage either in primary or secondary side of the transformer. The tapping (step-up/step-down) of the transformer must be auto controlled by VB program.For example, suppose if the desire voltage in the secondary of the transformer is 15V, but because of the loss, the voltage might drop to 12V. So, a sensor is used to detect this drop and send the message to VB. VB will process the message and send the reply signal to control circuit so that the voltage will step up (compensated) to 15 V. If the voltage exceeds 15 V, VB has to rectify it also.Can anyone please show me some guidances or circuit diagram of this project? Thank you!!!!
- Thank okorder
- Q: I just finish watching Transformers Revenge of the Fallen for the third time. IT was awesome I 'm getting it on DVD and hoping for it to come out as another transformers.
- i think no coz of the fight between megan and the director of thr movie he said he is tired of her already and is not planning to do the next one , unless somebody else direct it
- Q: The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
- You can explain the specific situation, your multi-power situation is what kind of situation, because we have not seen you refer to the "book"
- Q: I'll be going to Peru for 2 weeks and I was wondering if I could plug in my electronics over there. I read that they have both North American and European outlets and the voltage is 220 V and 60 Hz. My iPod wall charger and phone charger say 100~240 V (and my laptop charger says 100-240 V) and 50/60 Hz. Would I need to buy a transformer while I'm there so my stuff doesn't get all burnt out?
- If the charger/adapter says 100~240V it means you can plug it directly to the wall. Otherwise, you will have to buy a step-down transformer (240V to 120V). While you could buy a transformer at Walmart, Radioshack or BestBuy, I'd recommend buying it at any hardware store in Peru. They tend to be cheaper in Peru by some reason (less than $10). I would also recommend buying one of those plug adapters, since power outlets in Peru don't have a hole for the ground pin (they use 2-pin connectors).
- Q: I would like to attend a Transformers 2 Premiere where the cast will be present. Is that possible? Are these shows usually closed/private? Do I have to be in Hollywood? What should I do?
- I think so.
- Q: i can't seem to think of the name or artists of this song. All I could remember it has transformer lyrics (not the theme song). it has an old school hip hop/rap vibe to it but i need help of what's the name of it, thanks!!!
- Kurtis okorder
- Q: The zero line of the transformer can be connected with the ground wire. Why not leave it?
- Transformer ground is a neutral point directly grounded, and then there are protective grounding, just with it. The rest of the place, in addition to protecting the ground, the power system can no longer be grounded
