The utility model relates to a barite powder modifying and activating device for drilling fluid, and belongs to the technical field of barite powder processing. The device comprises a modification mixing bin, a material dispersing mechanism and a convection mechanism, air inlet holes are formed in the side face of the modification mixing bin, and a feeding mounting pipe is arranged at the upper end; the material dispersing mechanism is composed of a material distributing assembly and a material dispersing driving part, the material distributing assembly is located in the feeding installation pipe and is driven by the material dispersing driving part to reciprocate, it is guaranteed that barite powder is evenly dispersed into the modification mixing bin, local accumulation is avoided, and it is guaranteed that particles make full contact with a modifier; the convection mechanism comprises a convection assembly and is installed in the air inlet, airflow circulation is formed by generating pushing force, the uniform distribution condition of the barite powder in the modifier is remarkably improved through combination of the material dispersing mechanism and the convection mechanism, dynamic contact between the barite powder and the modifier is promoted, interaction between the barite powder and the modifier is further enhanced, and the service life of the modifier is prolonged. The modification is more thorough and consistent, and the modification efficiency and quality are improved.

The application discloses a high-voltage switch cabinet based on a modular structure, which has a cabinet body and an external pipe extending from the cabinet body, an instrument room, a handcart room, a busbar room and a cable room are arranged in the cabinet body, an instrument for measurement is arranged in the instrument room, a handcart is arranged in the handcart room, a contact box is arranged in the interior of the cabinet body, the upper contact box is connected with a busbar connecting piece through a busbar, the lower contact box is connected with a current-voltage transformer, a non-flat partition plate is arranged between the busbar room and the cable room, a handcart room cover plate, a busbar room cover plate and a cable room cover plate are arranged above the handcart room, the busbar room and the cable room respectively, a cover plate joint piece which is not integrated with the cover plate is arranged on the handcart room cover plate, the busbar room cover plate and the cable room cover plate, and the safety of the high-voltage switch cabinet is improved.
