Equipment power need to use isolation transformer ,?
Isolation Transformer, the main role of the isolation transformer is to make the primary side and the secondary side of the electrical completely insulated, but also to make the circuit isolated. Usually we use the AC power supply voltage a line and the earth connected to the other line and the earth between the potential difference of 220V, people contact will produce electric shock, and the secondary isolation transformer is not connected to the earth, it is any two lines and the earth there is no potential difference between the people touching any of the line will not occur electric shock, so it is safer.
The role of the isolation transformer
Many medical equipment, machine tools and mechanical equipment, etc., in order to protect personal safety, to prevent leakage of current, usually installed isolation transformer with the use of the safety maintenance of color TV, air-conditioning, commonly used in 1 to 1 isolation transformer for safety isolation to prevent the risk of electrocution, isolation transformer, the output and the input are completely different from each other. Isolation transformer output and input is completely "disconnected" isolation, so effectively on the input side of the transformer (grid supply supply voltage) has played a good filtering, anti-interference role, so as to provide a pure power supply voltage to the electrical equipment.
