The definition of isolation transformer and ordinary transformer
An isolation transformer, known as a safety transformer, is a type of transformer that separates the input power supply from the output load. Its main function is to reduce the AC voltage from the high voltage side and output it to the low voltage load through insulation isolation. The isolation transformer has excellent insulation and safety performance, which can effectively avoid electric shock injury and fire accident.
A common transformer, known as a non-isolated transformer, is a transformer that connects the input power supply and the output load to each other. It completes the voltage rise and fall by changing the number of windings. Ordinary transformers have the advantages of simplicity, high efficiency and low cost, but lack of isolation and insulation functions, and there are certain security risks in use.
The difference between isolation transformer and ordinary transformer
1. Insulation isolation: the isolation transformer can isolate the input power supply and the output load, which can effectively prevent electromagnetic interference and noise pollution of the power supply while ensuring the safety of the electrical appliance; Ordinary transformers do not have this isolation function, and the input and output are directly connected.
2. Insulation and voltage resistance: There is good insulation isolation between the high voltage winding and the low voltage winding of the isolation transformer, and it has a high insulation and voltage resistance, usually 1500V and above. The ordinary transformer has no isolation function, and its insulation voltage is generally only about 1000V, which is not suitable for occasions with high requirements for electrical equipment.
3. Safety: Isolation transformer can effectively protect personal safety, has a high electrical safety, the use of more safe and reliable. Ordinary transformers do not have insulation isolation function, in the event of leakage or other failures, may cause harm to personnel and equipment.
4. Scope of application: Isolation transformer is suitable for medical, electronics, communication and other high-demand fields; Ordinary transformer is suitable for household appliances, lighting and general power equipment and other occasions.
Conclusion
The above is the difference between the isolation transformer and the ordinary transformer, each transformer has its own application, it is very important to choose the right transformer according to the actual needs. If there are high requirements for safety and insulation, it is recommended to choose an isolation transformer, otherwise you can choose an ordinary transformer. At the same time, in the process of installing and using the transformer, it is also necessary to pay attention to the relevant safety specifications and operating guidelines to avoid accidents.
