The main function of the series is to isolate electrical equipment from the power grid Used in safety or anti-interference situations (often using D/Y, D/Yn △/Yo or Yo/△ connections) where there is no direct electrical connection between electrical equipment and power supply. Widely used in places such as subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises, and tunnels for power transmission and distribution, as well as for the use of import and export equipment.
Function of isolation transformer:
1. Electrical safety isolation
2. Has filtering and anti-interference function
3. Can effectively suppress the interference caused by high-order harmonics and lightning electromagnetic pulses introduced from the power line to this system
4. Can effectively suppress high-order harmonics emitted by electronic devices in this system from entering the power distribution network and causing interference to other devices and systems
5. It can fundamentally prevent system malfunction, data loss, or errors caused by ground potential disturbances
6. It can effectively prevent the hardware equipment in the system from being counterattacked and destroyed due to the sharp increase in the potential of the steel bars as a reference ground when the lightning protection device of the building is exposed to lightning
7. The reason why isolation transformers are widely used in construction is mainly because the secondary of the isolation transformer is not connected to the ground, and there is no potential difference between any two wires of the isolation transformer and the ground. So it's relatively safe. Isolation transformers are commonly used in electronic devices with electronic tubes and high operating voltages, such as tube amplifiers, oscilloscopes, etc. They can also be used for repairing power supplies
8. Overcoming center drift and improving power imbalance
9. Anti surge impact.
