Abstract

The invention discloses preparation technology for a ceramic envelope of a super-long high-voltage fuse. After a ceramic raw material is subjected to isostatic compaction to be prepared into a hollow tube through material distribution and spray granulation, a blank of a tube to be burned with a suspension burning head is turned first, and then a special calcination slab and suspension firing kiln tool are used to perform high-temperature calcinations in a high-temperature kiln by adopting a suspension burning and sleeving mode. The preparation technology is suitable for preparing the ceramic envelope of the super-long high-voltage fuse (the length is more than 400mm). The envelope is processed and produced by adopting a special ceramic process, is calcined by adopting a special calcination method, and solves the problems of the ceramic envelope such as deformation and bending. The preparation technology meets the operating requirement of the fuse. The preparation technology ensures that the qualification rate of products reaches more than 90 percent through practical production application, and realizes mass production.

Description

technical field

[0001] The invention belongs to the technical field of manufacturing electronic components, in particular to the manufacture of ceramic shells for high-voltage fuses. Background technique

[0002] With the continuous development of the power industry, high-voltage and ultra-high-voltage fuses have been widely used. There are many types of ceramic shells used in the manufacture of high-voltage and ultra-high-voltage fuses, according to the different fusing voltage levels and the materials used. However, the ultra-long (more than 400 mm in length) ceramic shells are easily deformed and bent in the conventional manufacturing process, so how to prepare such ceramic shells is a difficult problem at present. Contents of the invention

[0003] The purpose of the present invention is to provide a preparation process of ceramic shells for ultra-long high-voltage fuses to produce ultra-long ceramic shells for high-voltage and ultra-high-voltage fuses, and to solve th...
