Problems solved by technology
[0003] The existing power box is inconvenient to open and close the control door on the power box. Generally, it is manually operated, which is inconvenient to install and disassemble. When maintaining the power box, only one control door is used for operation, which is inconvenient to operate, and the control door The sealing performance is poor. When it is in contact with the ground, the water vapor on the ground surface is easy to enter the box. Secondly, when the power box is cooling, the dust is easy to enter the box, which is inconvenient to clean.

The invention belongs to the technical field of electric power engineering power boxes, and particularly relates to a high-voltage electric power engineering power box with a protection function, which comprises a base and a power box shell, two hollow cylinders are fixedly connected to the upper end of the base, empty grooves are formed in two sides of the lower end of the power box shell, and filter screens are rotatably connected to the inner walls of the two heat dissipation grooves. Arc-shaped blocks are fixedly connected to the inner walls of the heat dissipation grooves in the same side, the arc-shaped blocks abut against and are matched with the filter screens, positioning mechanisms are arranged between the reciprocating lead screw and the long rod and between the two filter screens, and a conical plate is fixedly connected to the upper end of the power box shell. According to the invention, opening and closing of the power box shell are conveniently started through the control motor, the power box shell can be sealed, moisture prevention is achieved, the two filter screens are arranged so that dust can be prevented from entering the power box when the two heat dissipation grooves conduct heat dissipation, and meanwhile the filter screens are conveniently cleaned.
Description
technical field [0001] The invention relates to the technical field of power engineering power boxes, in particular to a high-voltage power engineering power box with a protective function. Background technique [0002] Electric power engineering, that is, projects related to the production, transmission and distribution of electric energy, also includes projects that use electricity as power and energy in various fields in a broad sense. Distribution is mainly realized through high-voltage and low-voltage AC power networks. In the past 30 years, high-voltage direct current transmission technology has made rapid progress, and has been more and more widely used in some transmission fields. Therefore, as the development direction of transmission engineering technology, its focus It is to study UHV (above 1 million volts) AC transmission and DC transmission technology to form a larger power grid. In order to meet the needs of national economic and social development, the countr...
