The present invention relates to a high voltage fuse. An insulating housing (30) forms the appearance of the high voltage fuse of the present invention. An internal space (34) is formed inside the insulating housing (30). The internal space (34) is filled with arc extinguishing sand. A sleeve (50) is installed on the inner surface of the internal space (34). The sleeve (50) blocks explosive power by sparks generated from a melting part (62) of a fuse terminal (60) in the internal space (34) from influencing the insulating housing (30). A guide rib (54) is formed in the sleeve (50) to face both sides in the width direction of the fuse terminal (60). A guide slope (56) is formed in the guide rib (54) to distribute the explosive power by the sparks. A fixing protrusion (52) is formed to protrude in a position corresponding to the guide rib (54) on the outer surface of the sleeve (50). The fixing protrusion (52) is mounted in a fixing groove (36) of the insulating housing (30) to set a position in which the sleeve (50) is to be installed. The high voltage fuse according to the present invention as above can block the sparks from being transmitted to the outside by preventing damage to the insulating housing (30) by the sparks generated when the melting part (62) is melted, thereby preventing occurrence of fire. |
