Abstract
Description
Technical Field
[0001] The utility model relates to the field of moisture-proofing of ring network cabinets, and in particular to a moisture-proofing mechanism of an outdoor ring network cabinet. Background Art
[0002] In the power system, the ring main unit is an important power distribution equipment, which is widely used in urban power grids, industrial and mining enterprises, high-rise buildings and other places. However, due to the influence of environmental factors, especially in areas with high humidity, condensation is easy to occur inside the ring main unit, resulting in reduced insulation performance and even causing short circuit accidents. Therefore, the moisture-proof problem of the ring main unit has always been an important issue for the safe operation of the power system.
[0003] Traditional anti-moisture measures for ring main units mainly include heating, ventilation, and sealing. The heating method is to install a heater inside the ring main unit to increase the temperature inside the unit and prevent condensation. The ventilation method is to set vents to use air convection to remove moisture from the unit. The sealing method is to improve the sealing performance of the cabinet to prevent moisture from entering. However, these methods all have certain problems, such as high energy consumption for the heating method and difficulty in heat dissipation for the sealing method. Utility Model Content
[0004] The utility model is based on the above technical problems and proposes a moisture-proof mechanism for an outdoor ring network cabinet.
[0005] A moisture-proof mechanism for an outdoor ring network cabinet comprises: a cabinet body, a dust removal box is arranged at the air inlet of the cabinet body, the side of the dust removal box is connected with the air inlet, a plurality of dust shielding plates are arranged in the dust removal box, one end of the dust shielding plate is vertically fixed on a vertical plate, and the vertical plate is detachably mounted on the outside of the dust removal box; a bellows is arranged at the bottom of the cabinet body, one end of the bellows is connected with the lower part of the dust removal box, an array of exhaust outlets is arranged on the upper side of the bellows, an opening is opened on the outside of the bellows, a plurality of arrays of water absorption plates are arranged in the opening, the outer ends of the water absorption plates are fixed on a horizontal plate, and the horizontal plate is mounted on the outside of the bellows and closes the opening.
[0006] Preferably, a drain outlet is provided on the cabinet body, and the drain outlet is located below the air inlet and is connected to the dust removal box.
[0007] Preferably, the dust shield is a horizontally placed and downwardly inclined plate.
[0008] Preferably, the water absorbing plate is made of a polymer water absorbing material, and a plurality of arrays of small holes are provided on the water absorbing plate.
[0009] Preferably, the air outlet is transversely arranged on the upper side of the bellows, and the air outlet is perpendicular to and intersects with the water absorption plate.
[0010] Beneficial effect: The mechanism uses a downward-inclined dust shield to intercept dust entering the ring network cabinet. If the air contains more water vapor, a water-absorbing plate made of a polymer water-absorbing material can be used to absorb the water vapor to prevent a large amount of water vapor from entering the ring network cabinet. When the water vapor adsorption is saturated, the horizontal plate can be removed and replaced with a new water-absorbing plate. BRIEF DESCRIPTION OF THE DRAWINGS
