Hey. Users themselves can't turn! If you want to transfer, you can only transfer it by the manufacturer.
Because: for signal sampling of ordinary compensators, there are usually two modes: non-in-phase mode and cross-phase mode.
The same mode is to take the voltage and current of the same phase and sample 220V. In cross-phase mode, the phase voltage of one of the two phases and the current of the other phase are taken, and 380V is sampled. There is a phase difference of 90 degrees between in-phase and cross-phase, so for the 220V compensator and the 380V compensator, it is not only a matter of voltage amplitude, but also a big difference in signal processing, so the user cannot turn it by himself.
For more questions about reactive power compensation, you can go to our company to learn: please search for "Shenzhen Aote Electric Technology Center FAQ". Don't let send ** address, please forgive me!

Depending on what type of reactive power compensator you have, if you use a single-phase capacitor inside the capacitor, the voltage level will change to 380V. There is also a look at the voltage level of the capacitor.
Normally, the capacitor can work for a long time at times the rated voltage, but the life of the capacitor will be shortened!

As the old ladybug said, the voltage fluctuates more in this way, and the gains outweigh the losses.
UPS drops the voltage to 12V, which is to match the voltage of the battery, and its inverter output has a voltage stabilization function, which is not the same thing as a conventional passive transformer.
Electronic voltage regulators using the principle of reactive power compensation can be tried, but 220V is rare, and most are 380V.
If it's just a voltage problem, you are willing to spend some money, you can buy a constant voltage transformer, the performance is good, and it will come out at once.

Summary. The reactive power compensation device is mainly capacitors. It needs to compensate for the reactive power when the electrical equipment at the voltage level of 380 volts affects the power output due to the reactive power substandard.
Low-voltage reactive power compensation device is used in the occasion of more inductive loads, and there are many high-power inductive equipment in general factories. The reactive power compensation device can save electric energy and improve the power factor.

Use a three-phase ionization transformer for a kilometer, what method is used to stabilize the voltage.
1. The primary side is equipped with an on-load voltage regulating switch, 2. Appropriately reduce the impedance of the hand whisperer (there is no way to reduce the finished product, and if you reduce the impedance voltage carefully, the short-circuit current will increase).
Does a kilometer of three-phase ionization transformer affect the operation of the motor?
Influential, pro.
So what is the way to make the motor work properly?
Dear, this kind of dangerous work, it is better to ask a professional to come to your door to solve it for you.
Is there any way to solve it.
The power voltage booster adopts the principle of combining electromagnetic induction, electromagnetism, and frequency conversion to change the inductance of electrical appliances, change the capacitance of transmission lines and equipment, reduce line loss, and reduce reactive power to progressive voltage. An electric voltage booster (also known as a voltage booster) is a device that increases voltage. Some plant main power rises below normal and the source terminal voltage can be pushed up to normal or higher.

1) Estimate according to the transformer capacity.
The conventional design is 20% 40% of the transformer capacity, and more than 30%, for example, 1000kva transformer compensates 300kvar, 1600kva compensates 480kvar or 500kvar, and 2000kva compensates 600kvar.
2) Calculate by checking the "Reactive Power Compensation Capacity Calculation Coefficient Table".
The power output of the grid consists of two parts:
The first is active power: directly consume electric energy, convert electrical energy into mechanical energy, thermal energy, chemical energy or sound energy, and use these energy to do work, this part of the power is called active power;
The second is reactive power: it consumes electric energy, but only converts electric energy into another form of energy, which is a necessary condition for electrical equipment to be able to do work, and this energy is periodically converted with electric energy in the power grid, and this part of the power is called reactive power (such as the electric energy occupied by the electromagnetic components to establish the magnetic field, and the electric energy occupied by the capacitor to establish the electric field).

Summary. Because there is no need for isolation, a capacitor with reactive impedance can be used to step down the voltage in series, and the voltage limiting tube after the rectifier bridge is used, pay attention to the load situation, and the capacitor is formed as a constant current source.
380V to 24V: How to get 24V DC from 380V? No transformers are used.
Because there is no need for isolation, you can use a capacitor with no rock grinding impedance to step down the voltage in series, and limit the voltage of the stable limb jujube wax pressure tube after passing through the rectifier bridge, pay attention to the load situation, and the capacitor is formed by a constant current source.
The specific amount of current required.
Pro, that is, the output voltage is 24 volts, the current is ampere, and the frequency is 50 hertz per second. 50Hz, AC refers to rolling or alternating current, and 50Hz is the frequency. is with load capacity, 24 watt brigade standby). That is, the maximum energy band is 36 watts.
Yes. Voltage and current are the maximum power.
