Title:
FUSE COMPRISING PERMANENT MAGNET FOR INDUCING ARC DIRECTIVITY
Document Type and Number:
WIPO Patent Application WO/2020/138580
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the disconnection speed of an element (that is, decrease the blocking speed of a fault current) by arranging a magnet on the inner surface, the outer surface, or the inside of a porcelain tube included in a fuse and orienting, in a condensed manner, the traveling direction of arc energy into a constant direction according to Fleming's left-hand law by means of the magnetic field direction of the arranged magnet, thereby increasing the fault current blocking performance of the fuse. In particular, the present invention is characterized in that the location of the magnet arranged on the porcelain tube is arranged at the intermediate point between notching parts, a notching part point, or the porcelain tube corresponding to the intermediate point between notching parts and the notching part point.
