| 摘要 |
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.
