Performance characteristics

1.The features of this product are high efficiency and low loss.It can save a lot of operation cost,and the social benefits are very significant.

2.The iron cores are made of the imported high-conduction magnetism,cold-roll,and grain-oriented silicon-steel sheets.The iron cores and windings adopt the vacuum drying and vacuum oil-filling processes,which make the internal moisture down to the very low level.

3.The conservator is hermetically sealed,which make the internal running oil to insolate with oxygen and moisture efficiently.

4.The above features guarantee the transformer does not need do replace the oil during the normal operation,greatly decrease the maintenance cost,and prolong the service life.

Q: New on the transformer reported to stop, how to do,: First, if it is the implementation of non-industrial nature of electricity, there is no need to apply for stop procedures, directly out of the transformer on it.

Q: A CD player uses two 1.5 v batteries. If you want to plug it into a 120 v outlet, what kind of transformer will you need (Step up or Step down)? What must be the ratio of the number of turns in the primary to the number of turns in the secondary?: there is not any longer something incorrect with the turns ratio; the topic is that the sq. wave has severe frequency harmonics that are no longer nicely taken care of by technique of the ferrite. extra importantly, you're turning out to be to be magnetic saturation of the ferrite. you should do a calculation, based on the meant familiar contemporary, of the magnetization of the ferrite (a wisdom sheet on the middle will help), and from which you will calculate a suitable style of familiar turns.

Q: Transformers have any way of cooling: Selection of strong air-cooled cooling mode, when the pump and fan lose power supply, the transformer can not run for a long time. Even if no load can not run for a long time. Therefore, two separate power supplies should be selected for use by the cooler. ????When the oil-water cooling method is selected, it can not be operated when the pump cooling water loses power. The power supply should select two independent power supplies.

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.

Q: i want to know the actual lyrics for the Transformers theme that was re-covered by Mute Math. i heard that they changed some of the lyrics but i would like to know the exact changes, thanks.: Whoa she just gave you the best answer!!

Q: I was wondering which comic is the best read for an ongoing series about the the Transformers? It can be old or newMarvel, Dreamwave, or iDW. I was just curious because I have been a huge fan of the franchise since the first set of figures and generation 1 cartoon series but never read a single comic about them (which is actually very weird considering I am a huge comic geek) and just wanted to check one out.: transformers are crap why do you read them?!?!?!?!?!?!

Q: HI I recently heard a linkin park song and I forgot the title of it. My friend said this song is a theme song or something that's in the transformer movie I want to know the title of the song please help: Transformers-What I've Done Transformers:Revenge of the Fallen-New Divide

Q: What is his calculation? Trouble you prawn.: 250KVA transformer, the maximum capacity to load how much KW power? This is a bit of a problem, it is difficult to correct answer. Is it possible to ask how much the maximum load of the 250KVA transformer is KW? Or, how much amperes the maximum output current? If you ask, then answer you, the maximum output current is about 250 × 1.445 ≈ 361A or so

Q: How do I select a transformer connection group?: Both transformers are center-point direct-to-ground transformers. Dyn11 wiring group of the transformer because of its high-voltage winding is triangular wiring, so when the user produces three and three times the harmonic, can be formed in the triangular winding circulation, resulting in magnetic flux to eliminate this harmonic pollution for the grid. The Yyn0 transformer because there is no triangular winding, without this function. If only an independent power supply of small capacity transformer, you can use Yyn0 transformer, such a transformer everywhere, good production. If there is a transformer that may be supplied in parallel with other transformers, or as a backup power source for other power supplies, the same wiring group as other transformers should be selected. If it is recommended for large-capacity industrial transformers Dyn11 transformers are recommended to reduce the contamination of the grid by three or three times the number of harmonics.
