350 KVA 400V to 140V Al wire 3PH isolation transformer

Three-phase isolation transformer series products are widely used in industrial and mining enterprises, power plants, airports, high-rise buildings, subways, and other places with high safety and fire prevention requirements, for voltage conversion, lighting electrical facilities, power supply, and rectifier power supply.
Three-phase isolation transformer plays an important role in the power system, not only improves the safety and stability of the power system but also protects the connected equipment from electrical interference and damage.
Main advantages:
1, electrical safety isolation: three-phase isolation transformer of the primary side and the secondary side of the electrical completely isolated, the use of isolation transformer to make the secondary side of the ground suspension, so that the system of the ground current is not small enough to cause harm to the person. This isolation measure can effectively prevent the occurrence of electric shock accidents and protect personal safety.

2, filtering anti-interference: A three-phase isolation transformer with a filtering anti-interference function, effectively inhibits the introduction of high harmonics from the power line and lightning electromagnetic pulse on the system generated by the interference, but also inhibits the system of electronic equipment issued by the high harmonics into the power distribution network of other equipment generated by the interference.
3, inhibit high harmonics and lightning electromagnetic pulse interference: through specific wiring (such as Y / △ connection), a three-phase isolation transformer is conducive to the inhibition of the network side of the third harmonic, to reduce the impact of harmonics on the power system.
4, prevent the building lightning protection device flashback, hardware equipment destroyed by the counterattack: in the building lightning protection device flashback, the use of isolation transformers can prevent as a reference ground for the rebar potential rising sharply resulting in the system hardware equipment destroyed by the counterattack.
5, overcome the center point drift, and improve power supply imbalance: a three-phase isolation transformer can overcome the center point drift, improve power supply imbalance, and improve the stability of the power system.
6, anti-surge impact and filtering function: A three-phase isolation transformer also has an anti-surge impact and filtering function, and can start a large load of equipment to reduce the impact on the system voltage, to protect the equipment from the damage of surge current.
