Abstract
Improvements in medium voltage limiter fuses with built- in cut-out. The medium voltage limiter fuse with built-in cut-out, according to the invention, is formed of a tubular casing 1 at whose ends two contact caps 2 are fitted and inside which is a ceramic body 3 with high melting point fuse elements 4, with the special characteristic that included between one of the ends and the ceramic body itself 3 there is a labyrinth chamber 11, duly coupled with the ceramic body 3 and equipped with one or more hermetically sealed tubes 14, in which the low melting point fuse elements 14 are housed, these being connected to the fuse elements 4, to form as a whole a medium voltage limiter fuse with a built-in cut-out useful for protecting transformers in medium and low voltage electricity sub- stations, with highly efficient electric arc cut-out at low current intensities.
