摘要： The invention relates to EMC protection for a distribution transformer to eliminate health-endangering effects of magnetic fields in the vicinity of a dry-type transformer. According to the invention, a uniform and substantially seamless metal jacket (4) which damps the magnetic fields is disposed over a distribution transformer (1) and all of its four sides, substantially along their entire height, enclosing the distribution transformer from a small distance. Further, closed air circulation is provided between the metal jacket and the transformer, in which case a heat exchanger (6) is provided in connection with the metal jacket to cool the air circulation.

摘要： The invention relates to an electricity distribution structure including a low voltage transformer (1) and, connected thereto, a feed connection (2) on the high voltage side and a distribution busbar system (3) on the low voltage side. According to the invention, the low voltage transformer (1) is surrounded by a substantially solid metal shield (4) which provides the EMC protection, and the distribution busbar system (3) is supported on the inner surface of the metal shield. Furthermore, supported on the metal shield is a number of switch boxes (5), their switches (6) being coupled to the distribution busbar system, and being open to the transformer and provided on the outside with opening and closing metal hatches (7). In addition, inside the metal shield there is a cooling air circulation (8) for cooling the transformer and the switches.
