Abstract

This invention discloses a heating and drying method for a compound insulator porcelain core characterizing that the insulator is warmed up to 40-230deg.C and preserved for 4-36 hours in a device with a heating-up and heat preservation device. Advantage: the cement set on the connection positions with Portland cement, ceramic sand or quartz sand the porcelain, gossan and steel foot of a suspended insulator or the flange part of cylindrical or rod insulators is dried to expel unwanted water and gas to smooth the next stage work.

Description

Technical field [0001] The invention belongs to a composite insulator used in high-voltage power transmission and transformation projects, in particular to a heating and drying method for the insulator and the composite insulator ceramic core. Background technique [0002] At present, porcelain or glass insulators are widely used in high-voltage power transmission and transformation projects and power systems. And is gradually using composite insulators as the main device to replace the traditional porcelain or glass insulators. The advantages of composite insulators are obvious. However, due to insulators and composite insulators, especially silicone rubber composite insulators with better anti-fouling performance, due to the limitations of their manufacturing process and structural requirements, insulators and composite insulators produced by ordinary composite methods have good electrical properties and Anti-fouling performance, however, the so-called "zero value", "brittle fr...
