Working principle of 630 KVA-0.4/0.4 KV isolation dry-type transformer
630 KVA-0.4/0.4 KV isolation dry-type transformer works based on the principle of electromagnetic induction. Its core components include iron core and winding. The iron core is made of high-permeability, low-loss high-quality silicon steel sheets, which can efficiently concentrate and conduct magnetic fields and reduce hysteresis and eddy current losses. When 400V AC is input into the primary winding, an alternating magnetic field is generated in the iron core. According to the law of electromagnetic induction, this alternating magnetic field will induce voltage in the secondary winding. Since the voltage conversion ratio of the transformer is 400V to 400V, the turns ratio of the primary winding and the secondary winding is carefully designed to ensure the stability and precise matching of the input and output voltages.
