Description

Technical Field

[0001] The invention relates to the technical field of porcelain sleeve insulators, in particular to a sintering mould for a capacitor porcelain sleeve insulator. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, which can withstand voltage and mechanical stress. Insulators are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-type high-voltage wire connection towers with many disc-shaped insulators hung on one end. It is to increase the creepage distance. It is usually made of glass or ceramic, which is called an insulator.

[0003] After the porcelain sleeve insulator blank is shaped, it needs to be sintered, which is usually done in a drying room or a sintering kiln. Due to the large internal space of the sintering kiln, part of the heat cannot act on the porcelain sleeve insulator blank during sintering, resulting in too long sintering time and energy waste. The drying room uses waste heat to dry the blank, which takes longer. At the same time, after sintering, the surface temperature of the blank is high and needs to be left for a period of time to cool, which affects subsequent processing and causes low processing efficiency of the porcelain sleeve insulator. For this reason, we propose a sintering mold for capacitor porcelain sleeve insulators. Summary of the invention
