Product Description:

6-10kV Oil-immersed DistributionTransformers


1.   Introduction

6-10kV oil-immersed distributiontransformers with capacity 30-3150kVA are suitable for 6-10kV distributionnetwork system. Product complies with GB/T6451-2008 standards.

Type 9, 11 and 13 are classified byloss standard. Two types of oil tank are provided, they are sealed corrugatedradiating and sheet radiator. Voltage can be adjusted with load through switchinstalled.  

2.  Characteristics

Fully sealed corrugated tank has corrugatedsheet for transformer oil natural cooling. There is no oil storage cabinetneeded, so the oil is completely isolated from air. This design slows down theaging of oil, eliminates maintenance and extends the transformer life.

Q:Considerations when building a HV RF transformer?
Last transformer I made had a 1000 volt secondary, a 28 volt primary, ran at 22kHz, and a 20mA capability. It was wound on a ferrite form and was a cube about 1.5 inches on each side. I had a lot of difficulty keeping it from shorting out. I used lots of special HV insulating tape between winding layers, and managed to get a few working, but it was difficult. It was used in a voltage doubler to generate 2500 volts DC, so the entire winding had to withstand that voltage. Remember that there are only a few volts between consecutive turns, but after a hundred turns, that builds up to hundreds of volts. .
Q:Bridge rectifier, transformer vibrates and gets hot?
As Bill R says for working it out. As to how to answer in an exam, First write what is known, and what is wanted down. Write the appropriate equation(s) down and substitute values/simplify equation down as far as possible, you haven't been given all the information required to get that answer in the question. If you don't have all the data provided, and aren't expected to make assumptions then I'd argue the correct answer is actually the formulae produced when you've correctly put all that known in. But quite often you ARE expected to make reasonable assumptions. Sometimes an exam might have a cover page with assumptions to be made (if you don't make them you'll not get the answer right) sometimes you've just got to know how to make reasonable assumptions without being told. as it's 60Hz mains you're probably in the US. I'm in the UK so would it be reasonable for me to assume 50Hz mains if I were sitting the exam here? In cases where you have to make assumptions, it's usually a good idea to then state you are making an assumption. I suggest showing the difference which can happen if f is at least two different values eg finish with assuming f50Hz as mains is in the UK, then C needs to be C1followed on the next line by assuming f60Hz as mains is in the US, then C needs to be C2If you were feeling a little annoyed at those who wrote the exam, and wanted to make your point extra clear you might even throw in the case of f 120Hz. I believe many aircraft alternators generate AC at that f. Ask your teacher/lecturer about what kind of assumptions you might be expected to make. If they skirt around the issue maybe quote some Charles Babbage, and hope they laugh at the sarcasm ' On two occasions I have been asked,—Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out? I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.' —Charles Babbage, Passages from the Life of a Philosopher
Q:transformers history?
The gods Primus and Unicron nearly destroy the universe fighting until Primus tricks Unicron by imprisoning them both in metal planetoids. Unicron becomes giant transforming world devourer and Primus becomes Cybertron, bringing to life the transformer race that will fight Unicron in his stead. The robots of Cybertron eventually begin civil war which go on for millions of years, the evil Decepticons vs the heroic Autobots. Unicron finds Cybertron, the Autobot leader destroys him with the Matrix, the transformers fulfill their destiny. Their war continues until Cybertron is nearly depleted so the planet is reformatted and the race adopt Maximal and Predacon castes. New wars begin until balance is struck and Cybertron becomes technorganic paradise
Q:What kind of transformer is required to convert a 110 v microscope with a 6v, 10w bulb to a 220 v instrument?
You do not say what country you are in, so cannot give you links to an exact transformer. You are looking for a 220 to 110V step-down transformer. I am assuming you are going to plug the microscope into the transformer, rather than actually replacing the transformer in the microscope? The rating should be at least 10VA, personally I would go for at least 15VA for safety. That is quite a low rating and if you are lucky, you might be able to find a transformer meant for electric shavers really cheaply that should do the job. There is just one thing that concerns me, are you sure the transformer will only be powering the light and nothing else? If so, you will need a transformer that will handle a greater load. Somewhere on the microscope, or the PSU, or even it's box, there should be a rating Label, you can take the power supply rating from that. It is NOT true that VA Watts, but for something needing so little power, it should be near enough to give you the minimum rating. Good luck!
Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means
transformer: Transformer is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:How do you choose the public transformer capacity?
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:Altium designer DXP transformer in the same name how to change?
The same name is a painting of about 2-3mil radius of the solid circle, can not directly change, must be copied from the source file to the schematic library file can be changed, that is, to re-create schematic symbols.
Q:Transformers Revenge of the Fallen DS help?
Well, it sort-of has a create a bot feature, but not quite. In the beginning of the game, when you get your transformer as a protoform and once you get to do actual missions, you get to choose out of only three types of vehicles: A light but fast car, an all evened out sports car, or a heavy armoured tank (sort of like another game). However, you can only chose one because you are stuck with that form for the rest of the game. HOWEVER,with energon you pick up fighting other enemies and scanning computers or machines, you can customize stats (attack, agility, defence, ranged attacks, health, and regeneration of health) an customize your robot with different weapons. The game is not a wander-around game like its predecessor, but challenges are available. I guess after you beat the game or when going throughout levels, you play as transformers such as Starscream (beginning of Decepticons) or Optimus Prime (beginning of Autobots).
Q:Transformers- Autobots Post?
Transformers are cool!!!!!!! Transformers movie freaken awesome!!!!!! Transformers Animated its OK could be better, but still OK. Also can't wait until the next Transformers movie to come out!!!!!!!!!!!
Q:What Do You Think Of Transformers?
Yes I liked Transformers. It wasn't the best summer movie of all time when it came out last year but it was decent enough to satisfy. Megan Fox and Shia LaBeouf were very good in Transformers. I can't wait to see the second one.
