Description

Technical Field

[0001] The utility model relates to the field of insulators, in particular to a ceramic insulator structure. Background Technique

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a ground potential component, which can withstand voltage and mechanical stress. An insulator is a special insulating control device that plays an important role in overhead transmission lines. It consists of two main parts: an insulating part and a connecting fitting. In the early years, insulators were mostly used on telegraph poles. Slowly, many disc-shaped insulators were hung at one end of the high-type high-voltage wire connection tower to increase the creepage distance. Usually made of glass or ceramic, it is called an insulator. According to different installation methods, insulators can be divided into suspension insulators and post insulators. According to different insulating materials used, they can be divided into porcelain insulators, glass insulators and composite insulators. According to different voltage levels used, they can be divided into low-voltage insulators and high-voltage insulators. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators will not play a major role and will damage the service life and operation of the entire line. Most of the existing ceramic insulators are integrally formed structures. Therefore, when installed at the upper end of electric towers with different voltages, it is necessary to frequently replace insulators with different sizes and heights, thus affecting the versatility of the insulators. Based on this, it is necessary to provide an insulator that can adjust the number of insulator layers according to the voltage magnitude to enhance versatility. In addition, the existing insulator structure is inconvenient to disassemble and assemble. Based on this, it is necessary to provide an insulator that is convenient to disassemble and assemble. Summary of the Utility Model
