Description
Technical field
The present invention relates to a kind of preparation method of insulator, is a kind of preparation method of disk insulator specifically.
Background technology
Insulator is a kind of special insulation control, can in overhead transmission line, play an important role.Insulator is used for electric pole more, slowly develops in an end of high type high-tension bus-bar connection tower to have hung the insulator of a lot of plate-likes, and it is processed by glass or pottery in order to increase creepage distance usually, just is insulator.Insulator plays two basic roles in overhead transmission line; Be support wire and prevent that electric current from going back to ground; These two effects must be guaranteed; Insulator should be owing to environment and the electric loading condition various dynamo-electric stress that causes that changes lose efficacy, otherwise insulator just can not produce great function, will damage the use and the service life of whole piece circuit.
Insulator can be divided into pillar (pillar) insulator, suspension insulator, anti-pollution type insulator and bushing insulator by structure.Used insulator in the overhead transmission line, commonly used have pin insulator, shackle insulator, suspension insulator, porcelain pole arm, rod insulator and a strain insulator etc.Insulator commonly used now has: ceramic insulator, glass fibre reinforced plastic insulating, synthetic insulator, semiconducting insulation.
The main material of existing insulator is that chapeau de fer, toughened glass or pottery and steel pin are formed, and glued together with cement gel.Make insulator with these materials, its complex manufacturing technology, and also production cost is high.
