PROCESS FOR PRODUCING A CURRENT-LIMITING ELEMENT

摘要

The proposed process for producing a current-limiting element with shape memory effect is distinctive by using a rod made of epoxy composite material with graphite filler that expands under temperature. The weight of the filler is 15 ... 20 % of the weight of the material. The rod is deformed to the deformation value of 30 ... 45 % in a mold under compressing force, then cooled in the loaded state to a temperature that is lower then the vitrification temperature, and held at temperature of 50 ... 80 ?C until the initial length of the rod is restored.
