Study of Deterioration Improvement of Power Fuse

Abstract This paper aims to solve the problem deterioration of power fuses. The deterioration of a power fuse isa cause of failure misoperation by a normal current flowing reduplicatively to fuse the element. An extension survey of a load feature rerating power fuse examined the power fuse deterioration removal, the cause of the deterioration of the power fuse, the front-after, and the thermal variation of the inside transformer room electric power equipment. The transformer showed an average improvement of 6[ ℃ ].. The temperature of the electrical line showed 7~8[ ℃ ] improvement. The static condenser and direct reactor was 2~3[ ℃ ] high-state maintenance the temperature and equipment syntonization relationship. In the subject of study 0.5~1.0[ ℃ ] stabilizing three phase power fuse temperature differential was. Suggestion in the transformer room environment power equipment between the cause temperature happen elimination to deterioration of power fuse and temperature rise control Key Words :
