FUSE FOR HIGH-VOLTAGE APPLICATIONS

摘要

A current-limiting fuse for use at voltages between 23 kilovolts (kV) and 38 kV includes a body including a sidewall that at least partially defines an interior space; a fuse element in the interior space of the body, the fuse element wrapped around a non-conductive core and connected to first and second electrically conductive plates; and a non-bound particulate material in the interior space of the body, the non-bound particulate material including a plurality of pieces of the material with voids between at least some of the pieces. A fuse holder for use at voltages between 23 kV and 38 kV includes a housing for insertion in a sidewall of a transformer. The housing includes an exterior surface that defines an interior region. A fuse assembly is received in the interior region of the housing, the fuse assembly being configured to be replaced without opening the tank of the transformer.
