SHIELD COMBINATION DEVICE OF THE ULTRA HIGH VOLTAGE TRANSFORMER

摘要

PURPOSE: A shield combination device of an ultra high voltage transformer is provided to reduce an enclosure size and insulating oil by reducing insulating distance between the enclosure and a shield. CONSTITUTION: A male screw unit is formed in the outer circumference of a connection unit(3). A female screw unit corresponding to the male screw unit is formed in the inner circumference of a shield. The connection unit and the shield are combined with a screw assembly method. The shield includes a first shield(21) forming a cylindrical shaped shield and a second shield(22). A binding rail(23) is formed in the lateral edge of the first shield in a longitudinal direction. The first shield and the second shield are combined by inserting the binding rail into a guide groove(24). A stopper(25) is formed in the inner circumference of the first and the second shield. A bolt(26) is formed in the upper side of the stopper. The bolt is combined with a screwnut through a bolt hole of the connection unit.
