一种具有反时限特性曲线的栅式熔丝片
摘要：
一种具有反时限特性曲线的栅式熔丝片，属紧急保护装置领域。包括熔断体，其熔断体为偶数根；在熔断体的两端分别对应设置第一和第二连接片，其在熔断体与第一和第二连接片的连接处采用银钎焊方式，将所述熔断体的两端与第一和第二连接片分别固接为一体；然后将成为一体的栅式熔丝片整体进行退火处理；通过采用上述制作工艺和焊接方法，使得所述栅式熔丝片的耐电流冲击能力得以大幅度提高；具有反时限保护特点，其在流过1.3倍额定负载电流时确保在1个小时内不熔断；在流过2倍额定负载电流时确保在1个小时内必须熔断。可广泛用于户外低压配变熔丝箱用栅式熔丝的制造领域。
摘要（英）：

The invention discloses a grid type fuse wire sheet with an inverse-time characteristic curve, and belongs to the field of an emergency protection apparatus. The grid type fuse wire sheet comprises even number of fuse links, wherein first and second connecting sheets are correspondingly arranged at the two ends of the fuse links; the connection parts between the fuse links and the first and second connecting sheets are subjected to a silver soldering way for fixedly connecting the two ends of the fuse links and the first and second connecting sheets into a whole body; then the integrated grid type fuse wire sheet is subjected to annealing treatment wholly; by adoption of the manufacturing process and the welding method, the current impact resistance of the grid type fuse wire sheet is greatly improved; the grid type fuse wire sheet has the inverse-time protection characteristic; it is ensured that the grid type fuse wire sheet is not fused within 1h when 1.3 times of rated load current passes through the fuse wire sheet; and it is ensured that the grid type fuse wire sheet needs to be fused for sure within 1h when 2 times of rated load current passes through the fuse wire sheet. The grid type fuse wire sheet can be widely applied to the manufacturing field of the grid type fuse wires of an outdoor low-voltage distribution transformation fuse wire box.
