The present invention is mainly directed to a disconnector for an electrical substation for very high voltage in excess of 1100 kV, of the horizontal displacement type comprising a first moving part (2) and a second moving part (4), the said first moving part (2) and second moving part (4) each comprising at least two articulated arms (14, 16, 114, 116) which are arranged to make contact with each other through a free end. In the closed position, which is the closed position of the disconnector, the first arms (14, 114) and the second arms (16, 116) of each of the moving parts together define a non-flat angle (α) so that they form an arch, the two second arms (16, 116) being aligned with each other in a substantially horizontal position.
A horizontal displacement type disconnector for an electrical substation working at very high voltages in excess of 1100 kV, having a first moving part mounted movably on a first insulating support, and a second moving part mounted movably on a second insulating support, the said first and second moving parts each comprising a first arm and a second arm articulated relative to each other, the first arms being mounted on the respective insulating supports by a first longitudinal end, the second arms being arranged to make contact with each other through a second longitudinal end, wherein, with the disconnector in its closed position, the first arm and the second arm of each of the moving parts together define a non-flat angle so that they form an arch, the two second arms being aligned with each other in a substantially horizontal position.
An electrical substation for very high voltage of the order of 1100 kV, including at least one horizontal displacement type disconnector having a first moving part mounted movably on a first insulating support, and a second moving part mounted movably on a second insulating support, the said first and second moving parts each comprising a first arm and a second arm articulated relative to each other, the first arms being mounted on the respective insulating supports by a first longitudinal end, the second arms being arranged to make contact with each other through a second longitudinal end, wherein, with the disconnector in its closed position, the first arm and the second arm of each of the moving parts together define a non-flat angle so that they form an arch, the two second arms being aligned with each other in a substantially horizontal position.
