Embodiment Construction

[0017] The ultra-long high-voltage fuse ceramic shell is made of special porcelain formula. After batching, spraying granulation, and isostatic pressing, it is turned into a blank to be burnt with a hanging burner, and a special firing shed is used. And hang-fired kiln furniture, which is fired at high temperature in a high-temperature kiln by hanging and set. Products and hoisting pad rings such as Picture 1-1 , 1-2 shown.

[0018] The processing method of the ultra-long fuse ceramic shell is as follows: figure 2 As shown, the bottom layer is flat and high-temperature refractory shed board with a refractoriness of 1800°C; on the shed board is a special porcelain cylinder made of special ceramics, which needs to be fired at high temperature in advance to make porcelain. After grinding and processing, the thickness of the porcelain cylinder is uniform and the size is consistent. The thickness is adjusted according to the product weight (general thickness 10-15mm). After st...

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...
