The voltage stabilizing transformer is to install the voltage regulator and the transformer in a case, and adopts the modular configuration wiring, so that the transformer maintenance equipment is very convenient in maintenance. And save space, reduce purchasing costs and reduce line loss to provide efficiency, can withstand the moment high voltage, high current and bad temperature, humidity, vibration environment.
Component component of voltage stabilizing transformer
The transformer stabilizing machine mainly consists of an iron core, a primary winding, a secondary winding, a magnetic shunt, a resonant capacitor and a compensating winding.
Working principle of voltage stabilizing transformer
The no-load voltage stabilizing transformer, assuming the primary voltage U1, current I1, coil number N1, it is I1N1 due to magnetic flux leakage flux, loop air gap and air reluctance larger, so most of the magnetic flux through the secondary coil closed, little magnetic leakage.
When the load transformer is in load, the secondary current is I2, the secondary turns are N2, and the secondary magnetic flux is I2N2. The transformer core flux, common primary secondary, secondary flux can also be divided into a part, and a part of primary turns into the main flux, partly by magnetic leakage and secondary windings or even the only core for leakage reluctance generated by the main flux, secondary and primary instead.
In a general transformer, the secondary reverse magnetic flux is generated, and the primary current is increased to counteract the secondary flux, which essentially keeps the primary magnetic flux constant.
In the voltage transformer, the magnetic shunt, a secondary current same, produce the same flux, but to become a part of the flux leakage part to offset the main magnetic flux in the primary coil, the offset part is less, so the primary current increases little, really used to establish a secondary main flux is reduced.
Working performance of voltage stabilizing transformer
Due to the existence of the resonant coil, the current generated by the formation of magnetic flux and magnetic flux phase, the secondary working condition in deep saturation, and the primary work in non saturation, forming a stable alternating magnetic field magnetic circuit. Coupled with the compensation coil and the secondary coil of Nk series (reverse polarity), thus ensuring that when the input voltage changes within a certain range, the secondary output voltage unchanged, in order to achieve the stability of the output voltage.
