Isolation transformers are used widely in our daily life, such as medical equipment, autonomous equipment, home appliance audio equipment and security monitoring equipment. However, many users don’t know under what situation should we use isolation transformers. This article will analyse when is it needed by combining the function of isolation transformers.
1. When it needs to protect personal electricity safety from dangerous voltage, we need to use isolation transformers.
The main function of isolation transformer is to completely insulate the primary and secondary electric and isolate the loop. Usually when we connect a wire of ac supply voltage to the ground, the potential difference of the other wire and the ground is 220V. Electric shock will happen when people touch the wire. On the contrary, the secondary wire of isolation transformer doesn’t connect to the ground. There is no potential difference between any two wires of isolation transformer and the ground. It is safe that electric shock will not happen whichever wire people touch.
Isolation transformers are usually installed in many medical equipment, machine tool and mechanical equipment to protect personal safety from leakage current.
Moreover, while maintaining TV or air conditioner, 1:1 isolation transformer is commonly used for safety isolation to prevent the risk of electric shock.
2. If the power third harmonic and interference signal are serious, isolation transformer needs to be used to remove the third harmonic and reduce the interference signal.
The input and output of isolation transformer are isolated in open circuit completely which will help the input of transformer has a good filter and interference immunity, providing pure power voltage to the electric equipment.
Like the class A audio amplifier, many user choose isolation transformers. Besides, isolation transformers are used for preventing interference on the metro, in the high-rise building, at the airport, at the station, at the dock, in some mining companies, in the tunnel and other places of power transmission and distribution.
The above are just two common situations as examples. Additionally, there are still many occasions and situations where isolation transformers need to be used. Depending on its functions and advantages, isolation transformers are necessary in our life. While purchasing isolation transformers, we must choose the suppliers with quality assurance to avoid a counterproductive effect.
Ecko adopt high-quality 16000 gauss silicon steel sheet and pure copper wire in our isolation transformer. In addition to routine isolating process, we add the double copper foil electrostatic shield, ground lead, central insulation laye and 4000V high voltage resistance in our isolation transformer to avoid the electric shock, protect your personal safety and let you satisfied and assured in using our transformers.
