200A rated current's fuse -link and fuse -element thereof

The utility model discloses a 200A rated current's fuse -link and fuse -element thereof, the fuse of a photovoltaic fuse comprises a fuse body, length direction along the fuse -element body on the fuse -element body offers the soldering tin groove that the ordered series of numbers was provided with soldering tin, every the soldering tin groove includes the minor face of the long limit of two parallels, two parallels and connects four hypotenuses of long limit and minor face, whenever is listed as that the minor face in different soldering tin grooves is parallel to each other in the soldering tin groove, the hypotenuse is 0.29 with the tangent of the contained angle that the minor face becomes. The beneficial effect of the utility model: when passing through overload or short -circuit current on the fuse -element, it is fast to fuse. 本实用新型公开了种200A额定电流的熔断体及其熔体，包括熔体本体，所述熔体本体上沿着熔体本体的长度方向开设有数列设置有焊锡的焊锡槽，每个所述焊锡槽包括两条平行的长边、两条平行的短边以及连接长边和短边的四条斜边，每列焊锡槽中不同焊锡槽的短边相互平行，所述斜边与短边所成夹角的正切值为0.29。本实用新型的有益效果：熔体上通过过载或短路电流时，熔断速度快。
