Description

Technical Field

[0001] The utility model relates to the technical field of porcelain insulators, in particular to an anti-corona suspension type porcelain insulator. Background Art

[0002] Porcelain insulators are insulators made of electrical ceramics. Suspension insulators are one of many insulators. They are generally made of insulating parts and metal accessories glued together or mechanically clamped. Insulators are widely used in power systems. They are generally external insulation and work under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth or other conductors with potential differences. Multilayer suspension porcelain insulators contain multiple insulating parts made of electrical ceramics on the insulator.

[0003] However, the current impact-resistant device for suspension insulators is not convenient to replace when the insulator is damaged, which brings trouble to the staff. In addition, the current insulator is an integral device, which makes it more troublesome to install the insulator and increases the difficulty of the staff's operation. Therefore, an anti-corona suspension porcelain insulator is proposed. Utility Model Content
