Abstract
An overvoltage protection system for a transformer, designed to conduct a surge which has strayed into an electric line to earth, said transformer comprising a frame (1) and, mounted on top of it, feedthrough insulator (2), to which the electricity from the line conductors (3) flows via downleads (4), overvoltage protection being formed by a spark gap (7) provided between protective horns (5, 6) mounted in connection with the feedthrough insulator (2). The overvoltage protection system comprises a by-pass rail (8) extending substantially horizontally from the top end of the feedthrough insulator (2), the downlead (4) from the disconnector above being passed to one end of this rail, a downward directed first protective horn attached to the end of the by-pass rail (8) and forming an essentially straight extension to the downlead, and a second protective horn (6) mounted on the transformer frame (1) and placed below the first protective horn (5), said second protective horn (6) being connected from the transformer frame to earth by means of a separate earth conductor (10).
