How do you get a transformer to increase power, and how does a transformer change voltage?

The power of the finished transformer has been fixed, and if you want to change the output power, you must even change the primary wire diameter, because the primary power is secondary power, and at the same time, the window space of the iron core may not be able to accommodate the increased wire diameter. The secondary can be changed to a larger voltage, but it is also limited by the core window space and primary power, and the enameled wire with a smaller diameter than the original wire must be rewound (the voltage increases and the current decreases the original power), because the number of turns of the original coil must be increased by nearly double.

First of all, you have to determine what you are doing, and the question you ask is problematic, because voltage and power are two different things, and to make it 24V, you only need to add a few turns to the secondary coil.

First of all, the power of the transformer is determined by the core and wire diameter, and it is not easy to increase the power. The output from 9V to 24V does not increase the power, but only increases the output voltage (the maximum output current decreases).

The output voltage can be increased by increasing the number of turns of the secondary.

The easiest thing is that you go to change the transformer, you will have a lot of problems yourself, and there will be danger if you don't get it right.

You should say that you want to increase the voltage, and you can get it by using a few diodes and capacitors to form a voltage doubling circuit.

Look at the original number of ties of the input coil is recorded as n1 and the number of ties of the output is n2 According to the principle of transformer: n1 nx=u2 u1, then nx=u1n1 u2, so reduce the number of ties of the output coil (n2-nx).

It is a device that uses the principle of electromagnetic induction to change the alternating voltage. In our lives, transformers can be seen everywhere in order to ensure the normal current**. Now our society is becoming more and more enlarged, and the role of electrical energy in our lives is becoming more and more extensive.

Without electricity, we would have no energy in our lives, all kinds. Food, clothing, housing and transportation cannot be carried out normally, so electricity plays a pivotal role in our lives. However, the transportation of electrical energy is also relatively complex, and one of the most important devices is the transformer.

The main structure of the transformer is a device composed of a primary coil, a secondary coil and an iron core, which seems very simple for those who have studied electrical engineering, but it is indeed a bit difficult for us. On the question of how a transformer changes voltage, I have the following observations.

First, let's talk about the principle of transformer.

The principle of the transformer is to use the principle of electromagnetic induction to change the alternating voltage. It is a large device commonly used as a type of large-scale device for raising and lowering voltage, matching impedance and safety isolation in some electrical equipment and wireless circuits. In both cases, the value of the magnetic field passing through is constant, so the AC voltage can be changed.

Second, and then according to the structure of the transformer to know.

The composition of the transformer is roughly divided into two parts, one part is the iron core, and the other part is the outer coil. The core and coil create a magnetic field that senses an electric potential when an electric current passes through the magnetic field, and then the electric potential rises and falls. The core is the main part of the magnetic circuit in the transformer, which is usually composed of some iron with a high silicon content.

Third, finally, let's talk about the classification of transformers.

Transformers are mainly divided into five categories: power transformers, distribution transformers, dry-type transformers, amorphous alloy transformers and coiled core transformers. These types of transformers have their own unique roles and play a very important role in the current power system.

A transformer is a device that converts a certain value of current or voltage into another value of voltage or current of the same frequency.

The wires that pass through it undergo a current conversion to reduce the way the electrons are made, and then the voltage is changed and transported throughout the country.

It is through electromagnetic induction and then changes the voltage, and by changing the number of turns of the coil, the pressure is controlled, and the principle is not very complicated.

Some of the things in this will be blocked by electromagnetism, so that the voltage will be changed, which is also a physical principle.

The alternating magnetic flux is generated through the alternating current, and the magnetic conductivity of the iron core is used to induce the momentum of the alternating current and change the circuit voltage of the transmission.

The transformer can change the voltage, current, and impedance. The power cannot be changed.

The power of the transformer is determined by the magnetic flux cross-section of the transformer core, if the transformer core is selected, its signal beam power can not be increased arbitrarily (only allowed to be reduced), otherwise it will be hot and damaged.

On the other hand, if the wire wrapping is wound, then its number of turns per volt and the maximum allowable amount of current will also be confirmed, even if the input output power is not increased, it is not possible to increase the working voltage and current at will.

Due to the expansion of production capacity demand, the original application for the use of electricity capacity (usually calculated according to the capacity of the transformer, the unit is KVA) has been blocked to meet the needs of production and operation, and must apply for an increase in capacity on the original basis.

The transformer is composed of an iron core (or magnetic core) and a coil, the coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the rest of the windings are called secondary coils. It can transform AC voltage, current, and impedance. The simplest core transformer consists of a core made of soft magnetic material and two coils with different turns on the core.

Extended Materials. The transformer transformer principle was first discovered by Faraday, but it was not until the 80s of the nineteenth century that it began to be applied in practice. In the competition between direct current and alternating current, the ability to use transformers for alternating current is one of its advantages.

The transformer can convert the electric energy into a high-voltage and low-current form, and then convert it back, so the loss of electric energy in the transmission process is greatly reduced, so that the economic transmission distance of electric energy reaches farther. In this way, the power plant can be built far away from the electricity used. Most of the world's electricity goes through a series of transformers before it reaches the consumer.

The answer is that when the number of turns of the primary winding of the transformer increases, the capacity of the voltage regulator decreases to the capacity required for heat insulation.

Transformers cannot change power, but they can change power matching, which is often used in electronic circuits to maximize the output power of the circuit. Because the power depends on the voltage and current sensitivity, there are several ways to increase the power: first, the voltage remains the same, then the current must increase; Second, if the current remains the same, then the voltage must be increased; Third, the voltage and current are increased at the same time.

The maximum power of the transformer is determined by the magnetic flux cross-section of the core, once the core selection track is vacant, its maximum power can not be increased at will (only allowed to decrease), otherwise it will heat up, or even burn out. In addition, once the state and wire wrapping are made, then its turns per volt and the maximum allowable current are also determined, even if the input power is not increased, the voltage and current can not be increased at will, otherwise, it will also heat up or even burn out. The principle of the transformer is to change the voltage, not the current.

The methods of regulating the active power of the transformer are:1Adjust the voltage output of the transformer:

Adjusting the voltage output of the transformer can change the active power, and usually, as the voltage output increases, the active power also increases. 2.Change the loss of the transformer:

Adjusting the loss of the transformer can change the active power, and in general, with the decrease of the loss, the active power will also be reduced. 3.Adjust the coil of the transformer:

The coil of the regulating transformer can change the active power, and in general, as the radius of the coil increases, the active power also increases.

Summary. Hello dear, happy to answer your <>

The load current can be reduced according to the current of each line in each phase transformer, and sometimes the bus voltage needs to be adjusted. Based on the rated capacity of the transformer or field data, the active power is reduced by controlling the current in the field. Adjust the opening degree of the tap box of the transformer, change the current distribution coefficient between the phases in the transformer, make the current distribution more uniform, and reduce the active power.

Light-load commissioning tests of transformers are carried out in the field. The active power is reduced by adjusting the light load to achieve the purpose of energy saving. Adjust the load reasonably to reduce the active power of the transformer and reduce the loss of the equipment.

How to adjust the active power of the transformer.

Hello dear, happy to answer your <>

The load current can be reduced according to the current of each line in each phase transformer, and sometimes the bus voltage needs to be adjusted. According to the rated capacity of the variable voltage or field data, the active power is reduced by controlling the current in the field. Adjust the opening degree of the tap box of the transformer, change the current distribution coefficient between the phases in the transformer, make the current distribution more uniform, and reduce the active power.

The light load commissioning test of the transformer is carried out on site. By adjusting the light load, the power of the front is reduced, and the purpose of energy saving is achieved. Adjust the load reasonably to reduce the active power of the transformer and reduce the loss of the equipment.
