Abstract: The present invention relates to a transformer substation (6) comprising high-voltage switchgear (1), a low-voltage switchboard (3) and a transformer (2) which are electrically interconnected on the upper cover (5) of the transformer (2) through a shielded direct single-pole connection. The high-voltage electric connection (4) is carried out by means of a connection device (8) which, in combination with a control/protection device (10), allows carrying out the safe and integral protection of people and property against possible malfunctions in the transformer substation (6), limiting said malfunctions and preventing disturbances of the high-voltage and low-voltage network.

Abstract: The coupling system is of the type composed of a connector (1) which includes an insulating envelope (2), inside which are housed some conducting elements, which incorporates a semi-conducting layer 3) on the external surface of the envelope (2). This system incorporates a protection device (6) placed around the semi-conducting layer (3). The protection device (6) can, optionally, consist of a conducting ring connected to earth that the arc length in case of a dielectric failure of the coupling system. The protection device may incorporate an inductive current gauge and/or a capacitive voltage gauge that allow obtaining various electrical magnitudes of the high-voltage equipment.

This system incorporates a protection device (6) placed around the semi-conducting layer (3). The protection device (6) can, optionally, consist of a conducting ring connected to earth that minimises the arc length in case of a dielectric failure of the coupling system. The protection device may incorporate an inductive current gauge and/or a capacitive voltage gauge that allow obtaining various electrical magnitudes of the high-voltage equipment.
