Safety isolation transformerThe primary function is to completely insulate the primary side from the secondary side and isolate the circuit. Other companies use the high-frequency loss of their iron cores, and then suppress the high-frequency clutter into the control circuit. It can only be used in occasions where the power supply company is relatively small and the line is short. At the moment, the system's capacitance current to ground is too small to form a kind of damage to personal relations. There is also a very important way to protect their personal safety! This method can get very good isolation technique for risk analysis of voltage.
The safety isolation transformer belongs to the safety power supply and is generally used for maintenance, lightning protection and filtering in machine repair and overhaul. It is also a 1/1 device. The primary single-phase 220V, the secondary single-phase 220V, or the primary phase 380V, the secondary single-phase 380A line is connected to the soil, and the potential difference between the other line and the soil is 220V.
Electric shock occurs when people touch it. However, its secondary is not connected to the earth, and only half of the input voltage is needed between its arbitrary two lines and the earth. So when people get an electric shock, it's relatively safe. Another is that its output coupling to the input is completely "open circuit" isolated, so that it is useful to have an excellent filtering effect on its input. Then supply the pure power supply voltage to the electrical equipment.
Safety isolation transformerThe principle and general principle are the same. All through the use of various electromagnetic induction technology principles. It generally refers to a 1:1 device. Because these subordinates are poorly connected. There is no potential difference between any secondary line and ground. Use information security. Often used as a power supply for repair work.
