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 is passed through a melt fuse Hangzhou Which is good, then the melt blown fuses Which Hohhot arcing high temperature arc gas solid materials decompose rapidly produce large amounts of high-pressure gas, which will ionized gas with the arc tube both ends of the spray, issued a great sound and light the fuse Nanjing Which is good, and the AC current zero to extinguish the arc 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. An electrical fuse is low voltage distribution systems play a security role, the fuse is widely used in electrical equipment, power protection and protection fuses, electrical equipment when the power grid or a short circuit or overload fault, it can automatically cut off the circuit, Avoid electrical equipment damage, to prevent accidents from spreading. Which is good Handan fuses, fuse, power is supplied by the Xi'an Huayi 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. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
