Electromechanical disconnector between a high-voltage overhead transmission line and a voltage transformer

An electromechanical disconnector installed between an high-voltage overhead conductor of an high-voltage overhead transmission line and a voltage transformer mounted on a transmission tower for high-voltage overhead line conductors;

• said electromechanical disconnector comprising:
• a sectioning element and a sacrificial element arranged in series so as to electrically connect said conductor to said voltage transformer;
• said sacrificial element being made of a material suited to melt upon a passage of a fault current;
• and
• said sectioning element being suited to place itself at an air electrical insulation distance from said conductor following the melting of said sacrificial element.
