250KVA Three Phase step-up transformer

A three-phase step-up transformer is an electrical device used to convert low-voltage three-phase alternating current to high-voltage three-phase alternating current. It acts as a step-up transformer to provide the appropriate voltage for power supply equipment. The transformer mainly consists of three independent windings: a set of low-voltage windings, access to the low-voltage power supply; a set of high-voltage windings, the output of high-voltage current; and finally a set of neutral windings, used to connect the ground and provide current balance.
When the low-voltage winding inputs alternating current, the magnetic field will be transferred to the high-voltage winding through magnetic induction, thus generating high voltage in the high-voltage winding. This is due to the time phase difference of the three-phase currents causing the magnetic field to rotate as the transformer operates, thus multiplying the current. The three-phase step-up transformer uses the principle of magnetic induction, which utilizes the interaction of the magnetic fields created by the current in the transformer windings to change the voltage. The principle of operation can be described simply as the magnetic field generated on the windings feeding the lower voltage is transferred to the higher voltage windings, thereby increasing the voltage. Depending on the voltage ratio and the change in the winding, different degrees of boosting can be realized.
Three-phase step-up transformer has the following advantages: high efficiency, lower losses, reliability, stability, and long life. Therefore, it is widely used in various industrial and municipal fields, power transmission, grid regulation, and power supply backup.
