Q:Resistor in series with transformer primary?
Placing a resistor in series with the primary of a transformer has the same effect as placing a resistor in series with a resistive load: that is, depending on how much current is flowing, there will be a voltage drop across the series resistor which decreases the voltage seen by the primary of the transformer and a corresponding drop in the voltage produced at the secondary. If there is no current flowing, then there is no voltage drop at the primary and no drop at the secondary. For example, your 120:6 transformer produces 6 volts at the secondary with 120 volts applied to the primary. Suppose your secondary load draws 1 ampere, then the power is 6 watts and the load is 6/1 6 ohms. This current reflected back to the primary is 1/20 .05 ampere. The secondary impedance reflected back to the primary is 120/1/20 2400 ohms. So any load in the secondary is reflected back to the primary by the square of the transformer turns ratio: 20^2 400 in this case. 6 ohms in the secondary is reflected back to the primary as 6 * 400 2400 ohms in the primary. So now you can compute the voltage seen by the primary when you place a resistor in series with it. If the reflected load is Rr and the series resistor is Rs then the voltage seen by the primary will be Vp 120 * Rp/(Rs +Rp) and the secondary voltage will be 1/20 of that.
Q:Transformers are divided into several. What is the role of each? To be specific!
Types and characteristics of commonly used transformers      Commonly used transformer classification can be summarized as follows:      1, according to the number of points:      (1) single-phase transformer: for single-phase load and three-phase transformer group.      (2) three-phase transformer: for three-phase system of the rise and fall voltage.      2, according to the cooling method points:      (1) dry-type transformers: rely on air convection cooling, generally used for local lighting, electronic circuits and other small-capacity transformers.      (2) oil-immersed transformers: rely on oil as a cooling medium, such as oil from the cold, oil-cooled air-cooled, oil-soaked water, forced oil circulation.      3, according to the use of points:     (1) power transformer: for the transmission and distribution system of the rise and fall voltage.      (2) instrument with transformers: such as voltage transformers, current transformers, for measuring instruments and relay protection devices.      (3) test transformer: to produce high pressure, the electrical equipment for high-pressure test.      (4) special transformers: such as electric furnace transformers, rectifier transformers, adjust the transformer and so on.      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, connecting 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) 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.
Q:ok, i have a transformer and i need to know how high boost the electrical output.?
In addition, the number you gave is a part number for a transformer and the part number seldom, if ever tells you the turns ratio. And transformers only convert AC. I am afraid their information was totally wrong.
Q:Transformer ONAN?
Transformer ONAN cooling method for the internal oil natural convection cooling, that is commonly referred to as oil-immersed self-cooling. The cooling mode of the transformer is determined by the cooling medium and the circulation method. Since the oil-immersed transformer is also divided into the internal cooling mode of the tank and the external cooling mode of the tank, the cooling mode of the oil-immersed transformer is represented by four letters. The first letter: the cooling medium in contact with the winding. O -------- mineral oil or ignition of more than 300 ℃ of insulating liquid; K -------- Insulation liquid with ignition point greater than 300 ℃; L -------- ignition can not be measured insulation liquid; The second letter: the way the internal cooling medium is circulated. N -------- The oil flow flowing through the cooling equipment and the windings is a natural thermal convection cycle; F -------- The oil flow in the cooling equipment is forced to circulate and the oil flow flowing through the windings is the thermal convection cycle; D -------- The oil flow in the cooling equipment is forced to circulate, at least in the main winding oil flow is forced to guide the cycle; Third letter: external cooling medium. A -------- air; W -------- water; The fourth letter: the way the external cooling medium is circulated. N -------- natural convection; F -------- Forced circulation (fan, pump, etc.).
Q:What is an isolated ring transformer?
Isolated ring-type transformer is mainly focused on its insulation performance, between the primary and secondary must have a double insulation, so that the isolation of its own high efficiency, effective protection of equipment safety.
Q:High Voltage RF transformer design? ?
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:Transformer and the middle of what is the difference
In the week is the IF transformer or inductance coil, is a fixed resonant circuit with a transformer, the resonant circuit can be fine-tuning within a certain range, so that access to the circuit can achieve a stable resonant frequency.

Q:Transformer copper row selection
A general use of cable out, select 120mm2 line can be; second to use two 100 × 10mm copper, copper is to tin treatment. Copper specifications table recommended to find the national standard, see the copper discharge capacity and installation methods, after all, the transformer must be produced to meet the national standard.
