Title:
高圧溶断装置
Document Type and Number:
Japanese Patent JP7228684
Kind Code:
B2
Abstract:
A high-voltage fusing apparatus includes a current fuse, a temperature fuse, and a current-carrying fuse. The current fuse is connected in series with the temperature fuse, and a series branch of the current fuse and the temperature fuse is connected in parallel with the current-carrying fuse. A resistance value of the current-carrying fuse is less than a resistance value of the current fuse, and a fusing temperature of the current-carrying fuse is lower than a fusing temperature of the temperature fuse. The high-voltage fusing apparatus of the present invention can cut off a high-voltage circuit quickly, and effectively protect the high-voltage heating circuit from overheating.
