All-In-One Hybrid Transformer to be Installed at Construction Site

摘要

The transformer according to the present invention is an integrated hybrid transformer for installation on a construction site that transforms using three primary coils and three secondary coils that share the three primary coils and the core, respectively, and is a three-phase high voltage of 22900V and 60Hz. To supply 3-phase power to the 1st, 2nd, and 3rd high-voltage bushing terminals that receive inputs, the 4th, 5th, and 6th high-voltage bushing terminals that output the three-phase high-voltage of 3300V or 6600V and 60Hz, and the electric equipment for 380V 60Hz. It has three low-voltage bushing terminals and a neutral wire bushing terminal, and each of the three primary coils has one end connected in common and the other end connected to the first, second, and third high-voltage bushing terminals, respectively, and the three two Each of the car coils has one end connected in common to the neutral wire bushing terminal and the other end connected to the three low-voltage bushing terminals, respectively, and the 4th, 5th, and 6th high voltage outputting the three-phase high voltage of 3300V or 6600V and 60Hz as described above. Bushing terminals are characterized in that each is connected to the intermediate point of the primary coil.
