Abstract

An aspect of the present disclosure provides a shield (300) for a terminal (206) of a high-voltage electrical device (200) comprising a first shield element (301) having at least one axial opening (304) and at least one lateral opening (305), and at least one second shield element (302, 303), wherein the at least one second shield element (302, 303) is movable between a first shield position and a second shield position for selectively opening and closing at least one of the at least one axial opening (304) and the at least one first lateral opening (305). Further aspects provide a high-voltage electrical bushing (200) comprising a shield (300) according to the aspect above, and a transformer (100) comprising said high-voltage electrical bushing (200). Yet a further aspect provides a method (400) for installing a high-voltage bushing having a shield according to the aspect above.

Description

technical field [0001] Embodiments of the present disclosure generally relate to shielding for terminals of high voltage electrical equipment, in particular high voltage electrical bushings for transformers. In particular, embodiments of the present disclosure relate to shields for terminals having at least one lateral opening and at least one axial opening, wherein the shield is configurable such that the openings can be selectively opened or closed. More particularly, embodiments of the present disclosure relate to a method for installing a high voltage bushing having a shield according to the above aspect. Background technique [0002] High voltage transformers typically include a plurality of electrical bushings disposed therein to facilitate isolating conductors passing through a barrier, such as a grounded transformer housing. Electrical bushings for high voltage applications may include a dielectric component and means for mounting the bushing to a mounting surface. ...
