Abstract

The invention discloses a natural accumulated dirt checking field of an insulator. The natural accumulated dirt checking field comprises a transformer, a voltage divider, at least one supporting insulator and a frame formed by a portal rod tower, wherein the transformer is connected with the voltage divider, the at least one supporting insulator is arranged into a row at equal intervals, a frame bar is arranged at the upper end of the supporting insulator and used for supporting a cable connected with the voltage divider, and the frame combined by the portal pole tower is arranged above the supporting insulator. According to the natural accumulated dirt checking field, insulators of multiple forms are suspended on the frame, a V cluster included angle is regulated by regulating a suspension point position and a string length, an experimental investigation of charged or uncharged accumulated dirt characteristics of the insulators of 1000kV and below voltage classes can be carried out after insulators are charged, a research method for sampling a power grid running insulator is changed, the research scope is wide, and an important meaning is achieved for improving the power supply reliability and economy by a research result.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to an examination site for natural pollution accumulation of insulators. Background technique [0002] Dirt will be deposited on the surface of insulators exposed to the air for a long time. In snow, fog, drizzle and other humid weather, the soluble salts in the dirt will dissolve in water and become conductive, reducing the dielectric strength of the insulator, and even causing Pollution flashover leads to interruption of power supply, which seriously affects industrial production and people's daily life. Under certain environmental conditions, the insulator material, type and string type have a significant impact on the amount of dirt deposited on the surface of the insulator, so different materials (porcelain, glass and composite, etc.), different umbrella shapes (common, bell, double) Umbrella, triple umbrella), different string types (I strings, double I strings, V str...
