Ventilated moisture-proof power cabinet

Abstract

The invention relates to the field of power and relates to a power cabinet including a machine frame, wherein an air inlet is formed in the outer side of the rack; a second bearing is mounted in the middle of the upper end of the rack; a rotating shaft is mounted in the middle of the second bearing; at least three second bent rods are mounted at the upper part of the rotating shaft; a rain shielding film is covered between the second bent rods; a supporting rod is mounted at the upper end of the rotating shaft; at least three first bent rods are installed at the upper end of the supporting rod. A wind bearing film is covered between the first bent rods; a ventilation device is mounted at the lower end of the rotating shaft; a placing device is mounted in the rack; through the arrangement of a rotating shaft, a second bent rod, a rain shielding film, a first bent rod, an air bearing film and a ventilation device, air in the rack drives the air bearing film to rotate through natural wind; the wind bearing film drives the rotating rod to rotate, and the rotating rod drives the ventilation device through the driving gear; so that air is circulated, water vapor is prevented from condensing and dripping on electrical apparatus elements due to humid and unventilated weather, and large-area popularization is facilitated.

Description

Technical field [0001] The invention relates to the field of electric power, in particular to a ventilation and moisture-proof electric cabinet. Background technique [0002] At present, with the rapid development of power technology, outdoor transformer boxes, power distribution cabinets and other cabinets used to meet the installation of various electrical components have also been adequately developed. However, after the installation of transformer boxes, regular or Unscheduled maintenance and inspection are to prevent accidents caused by aging or short circuit of electrical components inside the substation, and to reduce the loss of public property. However, the electrical components inside the substation will produce a large amount of electricity during long-term operation. Especially in summer, due to the small space inside the transformer box, it is not only not conducive to the maintenance and treatment of the inside of the transformer box, but also makes it difficult for...

Problems solved by technology

[0002] At present, with the rapid development of electric power technology, outdoor transformer boxes, power distribution cabinets and other cabinets for the installation of various electrical components have also been fully developed. However, after the installation of the transformer box is completed, regular or Unscheduled maintenance and inspection, this is to prevent accidents caused by aging or short circuit of the electrical components inside the transformer box, and reduce the loss of public property, but the electrical components inside the transformer box will generate a large amount of Especially in summer, due to the narrow space inside the transformer box, it is not only not conducive to the construction personnel to repair and deal with the inside of the transformer box, but also makes it difficult for the heat inside the transformer box to dissipate into the air, which is easy to The electrical components inside the transformer box will be damaged due to high temperature, or the circuit connection wires will be short-circuited due to high temperature, which will greatly increase the hazards of using conventional transformer boxes, and the humid environment will cause corrosion of power cabinets or metal devices, shortening service life, for this reason, we propose a power cabinet dehumidification device

[0003] After retrieval, the Chinese Patent No. CN108988167A discloses a power cabinet dehumidification device, including a power cabinet, the upper end of the power cabinet is provided with a breathable cabin, and the lower end of the power cabinet is heated by a grid plate It is fixedly connected with the base, the inner cavity of the base is provided with more than two motors, the output end of the motor is fixedly connected with the first fan, and the inside of the power cabinet is provided with a drying chamber in the circumferential direction, and the inner cavity of the drying chamber Filled with silica gel, the top plate of the power cabinet is provided with more than two fixing devices, the fixing device is provided with a second fan, the top of the breathable cabin is provided with a top cover, and the edge of the top cover is fixedly connected to the rain The side wall of the air-permeable cabin is provided with more than two filter screens. The power cabinet dehumidification device has a fast dehumidification speed and a good dehumidification effect, prolonging the service life of the power cabinet and power components, making the use of the power cabinet safer, but The device uses the motor to dehumidify the power cabinet, which requires power consumption and high cost of use. At the same time, due to the use of the motor, the manufacturing cost is also high, which is not conducive to large-scale promotion
