Q:Wire sizes in the interior of transformers?
You might want to review the source below to help you understand how power transformers operate. I'll try to explain how they are able to use smaller wire gauge to serve the same load you have to use larger wire gauge for. You recognized that if you can cool a conductor, then it may call more current.
Q:Bridge rectifier, transformer vibrates and gets hot?
The transformer may be vibrating because the winding inside have loosened up and vibrating due to the varying magnetic field. But it is quite possible it may have a shorted winding this will definitely make it heat up and vibrate. Disconnect the filter capacitors and plug it back in if the transformer stops vibrating and/ or the transformer doesn't overheat you have a leaky filter capacitor.
Q:Why is the transformer coil insulation?
Because the transformer is used in different environments, according to different insulation level selection, can extend the life of the transformer. 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:What is the transformer absorption ratio (R60 / R15)
Absorption ratio = R60 〃 / R15 〃 For the same insulating material: the moisture or defective absorption curve will change, so you can determine the insulation curve based on the insulation is good or bad, usually in megger in 15 seconds and 60 seconds of the insulation resistance ratio (This is the absorption ratio, expressed by the K value), because the insulation of the degree of moisture increases, the leakage current increase than the increase in the starting value of the absorption current is much more, expressed in the insulation resistance is: megger in 15 seconds and 60 seconds of the insulation resistance is basically equal, so the K value is close to 1; when the insulating medium is dry, because the leakage current is small, the current absorption is relatively large, so the K value is greater than 1. Experience: When the K value is greater than 1.3, the insulating medium is dry, so that by measuring the absorption ratio of the insulating medium, it is possible to determine whether the insulating medium is damped and K is a ratio which eliminates the geometric dimensions of the insulating structure , And it is the same temperature measured under the value, without going through the temperature conversion, the comparison of measurement results is very convenient.
Q:Power transformer primary current and secondary current
Once refers to the power side, the second refers to the load side
Q:Transformers and frequency question?
Your answer is correct. The frequency has no effect on the turns ratio. The frequency does effect the required primary inductance, however. More turns with 50Hz, about 20% more for same magnetizing current as with 60Hz. I am assuming your generator can change frequency.
Q:How is the transformer sorted?
4, according to the winding form points: 1) Double winding transformer: Used to connect two voltage levels in the power system. 2) Three-winding transformer: generally used in power system area substation, connect three voltage levels. 3) Autotransformer: Power system for connecting different voltages. Can also be used as a normal step-up or down transformer. 5, according to the core form points: 1) core transformer: for high voltage power transformers. 2) Amorphous alloy transformer: Amorphous alloy core transformer is a new type of magnetic materials, no-load current drop of about 80%, is the energy-saving effect of the ideal distribution transformer, especially for rural power grids and developing regions such as load rate Lower place. 3) shell transformers: special transformers for high current, such as electric furnace transformers, welding transformers; or for electronic equipment and television, radio and other power transformers.
It was pretty cool, nice trip down memory lane. Autobots and Bumble Bee and the bit when he blasts who's gonna drive you home cheesy and funny!!!
Q:The specific steps and procedures for installing the transformer
Hello, you said it should be the frequency transformer installation steps it. Steps are as follows: first equipped with skeleton Oh, and then use the winding machine around the enameled wire, and then add the fuse (if the customer specified to), then dip tin, dip tin is the dressing, the package is finished shake the film, shake the film is Plus shell, such a transformer to do a good job. I hope I can help you.
Q:iPod Touch Transformer Question?
I feel your pain, but Transformer only works on itouches with the firmware 2.2 or under. If your still want a iphone look-a-like this is what I did and I works great Maybe even better than tranfromer!: 1. Download iCall, textPlus, and Flicket off app store. 2. Download CompassF app off cydia. 3. Download theme iPhoney theme off Cydia 4. Download Better 3G WiFi (turns wifi bars into 3g) 5. turn on the 2 themes ATT bars will be added w/ iPhoney automadiclly 6. Download SBSettings, extras, and turn on the numeric battery. (like 3Gs) 7. Lastly, if you want to go that extra mile Im working on a Theme that changes the iTouch settings to iPhone ones with wallpaper on main page. And thats it, the Icons and names of the 3 app store apps should change to camera, messages, and phone. The spotlight should say, Seach iPhone and thats pretty much it. Not only does the phone work with wifi now looking just like the iphone dialpad, and so does messages. So I think this is better than Transformer and wont mess up ur touch like transformer would. Hav fun messing with your friends minds lol! :)
