Transformers for rectifier

Transformers for rectifier (Serie: TTR)

Description Construction:

The windings of these transformers are made ​​of copper wire (double insulated with Class H insulation or double Nomex tape) or performed with aluminum tape. On request, a copper band version is possible.

The transformers are protected by a vacuum pressure impregnation with a solvent-free polyester resin and anschließßender heat treatment. The magnetic core is made from grain oriented sheets. The transformer is designed for natural air cooling. With enhanced cooling size and weight can be reduced.

Applications:

These transformers are used in power rectifiers. They are used both for isolation and voltage matching between the main network and load. Transformers with one secondary winding (Dy11) are suitable for 6-pulse rectifier and f ¨ r 12-pulse rectifier used those with two secondary windings (Dd0y11).

Three-phase transformers (Serie: TTR)
