The working principle of a small booster transformer is amazing!
In general, R-type booster transformers are mainly used to convert low-value alternating voltage into another high-value alternating voltage transformer. At present, there are relatively few transformer manufacturers in China that can effectively achieve instantaneous boost, and the boost transformer requires strong instantaneous start boost capacity and good boost effect. The difference between him and the ordinary transformer is that there is no excitation pressure regulation switch, no load transfer gear ability, in general, this tap-changer has a short disconnection process in the process of shifting gears. Disconnecting the load current can cause the arc between the contacts to burn out the tap-changer or short circuit, so the transformer needs to be powered off when it needs to adjust the gear.
The principle of the booster transformer is to convert low AC voltage, large current and small impedance into high AC voltage, small current and large impedance. When there is alternating current in the main coil, AC flux is generated in the core, which senses the voltage in the secondary coil. If you use a battery, because it is DC, you need to add a switching circuit to the input circuit and convert it to a constantly changing voltage. Only in this way can a high alternating voltage be obtained at the output end.
The input of the transformer must be an alternating power supply, and its output voltage is proportional to the ratio of turns of the input coil. The main function of the booster transformer is for electrical isolation, one is to maintain equipment, the other is to maintain personal safety and prevent dangerous voltage. The input and output capacitive coupling of the booster transformer is very small, which has a more effective effect on the interference of lightning, discharge, power grid switching, motor starting and other power grid noise.
The feature of the booster transformer is that the use of the booster transformer can generate a new neutral line to prevent the abnormal operation of the equipment due to poor neutral lines in the power grid. It can also prevent the waveform distortion caused by nonlinear load, so as to avoid the nonlinear current distortion affecting the normal operation of the communication power supply. The above are some of the working principles and characteristics of small booster transformers, hoping to help us play a reference role in the selection of booster transformers.
