1.Isolation transformer refers to a transformer in which the input winding and output winding are electrically isolated from each other to avoid the danger caused by accidentally touching live objects (or metal parts that may be live due to insulation damage) and the earth at the same time. Its principle Like ordinary dry-type transformers, it also uses the principle of electromagnetic induction to mainly isolate the primary power circuit and float the secondary circuit to the ground to ensure the safety of electricity.
2.The isolation transformer is a safe power supply and is generally used for machine repair and maintenance. It plays a role in protection, lightning protection, and filtering.
3.The secondary of the isolation transformer is not connected to the earth, and there is no potential difference between any two lines of the isolation transformer and the earth. People will not get electric shock if they touch any line, ensuring safety.
4.The output end of the isolation transformer is completely isolated from the input end by "open circuit", which effectively plays a good filtering effect on the input end of the transformer (power supply voltage supplied by the power grid), thus providing pure electrical equipment. supply voltage.
Product Feature
1.Low loss, low partial discharge, low noise, strong heat dissipation, and can operate at 120% rated load under forced air cooling conditions.
2.It has good moisture-proof performance and can operate normally under 100% humidity. It can be put into operation without pre-drying after shutdown.
3.It is safe to operate, fireproof, and pollution-free, and can be installed directly in the load center.
4.Equipped with a complete temperature protection control system to provide reliable guarantee for the safe operation of the transformer.Maintenance-free, simple installation and low overall operating cost.
Three Phase Dry Type Transformer Core
The core is beveled and stepped for maximum performance and minimal bulk. After the magnetic steel is produced by the cutting machine, it is continuously cut into specific lengths by the automatic stacking machine, and then automatically stacked. The correct size is ensured during the entire stacking and assembly process to ensure the high quality of the product.
Dry Type Distribution Transformer Winding
The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.
Dry Type Power Transformer Accessories
All the accessories you need to customize our products to your needs.
The casing is made from bolts on a steel plate with removable panels for attachment and tape. Depending on the application and your requirements, the surface treatment can be galvanized, painted. The design is optimized to ensure the required cooling of the transformer at all levels of protection. The enclosure can be shipped assembled on the transformer or flat packed for on-site assembly.
