Abstract

The invention discloses a 360-degree pneumatic cleaning purifier for cleaning pillar insulators. It includes a fixed frame, left and right movable mechanical arms, left and right cylinders, left and right pneumatic solenoid valves, a horizontal cornerer, a vertical cornerer and four Pneumatic purge cleaning brush. The two ends of the fixed frame are hinged to connect the left and right movable mechanical arms. The left and right cylinders are set outside the two ends of the fixed frame. The left and right pneumatic solenoid valves are respectively placed on the left and right cylinders or fixed mechanical arms. The outside of the symmetry axis of the fixed frame is connected to a horizontal angle device. The cornerer is connected to the vertical cornerer, and the four pneumatic purging brushes are installed on the fixed frame and the movable mechanical arm respectively; the entire 360-degree pneumatic cleaning purifier is installed on the insulating rod or insulating lifting mechanism by the vertical cornering device. This cleaning and purging device can perform any repeated 360-degree cleaning and purging of insulators without cleaning dead corners, and is suitable for high and low voltage live and non-live operations at various voltage levels.

Description

technical field

[0001] The invention relates to a pneumatic cleaning machine for cleaning post insulators, in particular to a pneumatic cleaning purger for 360-degree rotating brush cleaning and synchronous cleaning of insulators. Background technique

[0002] Substation insulators are the support and insulation facilities for high-voltage equipment in substations. Due to being outdoors all the year round, the surface of insulators is prone to form a dirty layer. These filthy thing Wet by heavy fog, light rain, etc., will form electrolytes to destroy insulation, and easily cause pollution flashover accidents. Pollution flashover accidents can cause line tripping and power outages in the slightest, and disconnection of the power grid in severe cases, resulting in large-scale catastrophic power outages. Therefore, regular cleaning and decontamination of insulators is required.

[0003] Our country has carried out anti-pollution flashover work for more than 40 years. The wi...
