1, insulation isolation: isolation transformer can be the input power and output load isolation, in order to ensure the safety of electrical appliances at the same time, can effectively prevent the power supply of electromagnetic interference and noise pollution; ordinary transformers do not have this isolation function, the input and output are directly connected.
2, insulation voltage: isolation transformer high-voltage windings and low-voltage windings have a good insulation between the isolation, has a very high insulation voltage capability, for 1500V and above. The ordinary transformer has no isolation function, its insulation withstand voltage only 1000V, for the higher requirements of electrical equipment is not applicable.
3, safety: isolation transformer can effectively protect personal safety, has high electrical safety, the use of safer and more reliable. Ordinary transformer has no insulation isolation function, once the leakage or other faults, will cause harm to personnel and equipment.
4, the scope of application: isolation transformer for medical, electronics, communications and other high requirements of the field; ordinary transformers for household appliances, lighting and power equipment and other occasions.
5, isolation transformer is the input winding and output winding with electrical isolation of the transformer, isolation transformer to avoid accidentally touching the charged body at the same time, the isolation of the transformer is to isolate the original and secondary winding coil of the respective current.
