Title:
HIGH-VOLTAGE FUSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/147327
Kind Code:
A1
Abstract:
A high-voltage fusing apparatus, comprising: a current fuse, a temperature fuse and a current-carrying fuse, wherein the current fuse is connected to the temperature fuse in series; series branches of the current fuse and the temperature fuse are connected to the current-carrying fuse in parallel; a resistance value of the current-carrying fuse is less than a resistance value of the current fuse; and a fusing temperature in the current-carrying fuse is lower than a fusing temperature of the temperature fuse. The high-voltage fusing apparatus of the present application can quickly cut off a high-voltage circuit, and can effectively perform overheating protection on a high-voltage heating circuit.
