Each has a minimum melt melting current. Corresponding to different temperatures, different minimum melting current. Although the current impact of the external environment by, but in practical applications can not consider. Rated current ratio is generally defined minimum fusing current melt and melt melting coefficient Jiaozuo smallest high-voltage fuse, commonly melt melting coefficient greater than 1.25 Xinxiang high voltage fuses, ie melt rated current of 10A current not blow when 12.5A less. Expulsion fuse is installed in the melt by a solid insulating tube gas material. The solid material can be gas or electric and plexiglass anti paperboard materials. When the short-circuit current through the melt Suizhou high voltage fuses, fuse melt immediately arcing, high temperature gas arc solid materials decompose rapidly produce large amounts of high-pressure gas, which will ionized gas pipe with both ends of the arc spray fuse issue great sound and light, and extinguish the arc AC current zero and breaking current. The insulating tube is typically mounted on an insulating holder, the overall composition of the fuse. Sometimes the upper pipe insulation made of movable type, in breaking current immediately after disengagement and fall, this jet, commonly known as drop-out fuse fuse. Generally applicable to a voltage higher than 6 kV outdoor occasions. Shiyan high-voltage fuse fuse _ _ Huayi electricity provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
