Abstract

The present invention discloses a high-voltage drop-out fuse tube which comprises an arc-extinguishing tube and a high temperature resistance epoxy glass cloth wrapped insulating tube. The arc-extinguishing tube is sleeved in the high temperature resistance epoxy glass cloth wrapped insulating tube and is made of an arc quenching material. The arc quenching material comprises, by weight, 60% to 65% of polyester, 20% -25% of epoxy adhesion agents, and 10% -20% of melamine filler. Through the above mode, the high-voltage drop-out fuse tube has strong anti-drop performance and is difficult to be damaged or broken, and the high-voltage drop-out fuse tube has good thermal stability and insulating performance.

Description

technical field [0001] The invention relates to the field of fuses, in particular to a high-voltage drop-out fuse fuse tube. Background technique [0002] Drop-out fuse is the most commonly used short-circuit protection switch for branch lines of 10kV distribution lines and distribution transformers. It is economical, easy to operate, and adaptable to outdoor environments. It is widely used in 10kV distribution lines and power distribution The primary side of the transformer is used for protection and equipment switching and switching operations. [0003] High-voltage drop-out fuse consists of three parts: insulating support, moving and static contacts, and fuse tube. The dynamic and static contacts are installed at both ends of the insulating support, and the fuse tube is composed of an inner arc suppression tube and an outer phenolic paper tube or oxygenated glass fiber cloth tube. [0004] The fuse tube is a key component of the high-voltage drop-out fuse, and its quali...
