Enclosed Fuse: Closed divided filler fuses and fuse no fuse two fillers, shown in Figure 3 and Figure 4. Filler generally with a square ceramic tube fuse, built quartz sand and melt Taizhou high-voltage fuse, breaking ability, for voltage below 500V, current levels 1KA following circuit. No filler sealed fuse will melt into the closed cylinder, breaking capacity fuses smaller, less for 500V, 600A under the power grid or distribution equipment. Visits to check the fuse: 1, check the fuse and melt rating is compatible with the protection device; 2, check the fuse look for damage, deformation Yancheng high-voltage fuse, porcelain insulator part or without blinking traces of discharge; 3 Check the fuse is intact the contact point, in close contact, with or without overheating; 4, blown fuse indicator signal is normal. Jinhua high voltage 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!
