Abstract
The utility model discloses a no consumption open-air electric power facility prevents dew structure, no consumption open-air electric power facility prevents dew structure includes: a facility body; the open-air power facility of no power consumption prevents dew structure still includes: a slanted roof and a lower convection orifice; the inclined roof is fixedly arranged on the upper part of the facility body and completely covers the upper part of the facility body; a drainage gap is reserved between the inclined top and the upper part of the facility body in the downward inclined direction of the inclined top; the lower convection hole is arranged at the lower part of the surface of the facility body and is communicated with the inside of the facility body. When the ambient temperature is cooler and the air humidity is great again with solving prior art, the inside air that is heated of looped netowrk cabinet is heated and rises and meets the looped netowrk cabinet top that cold, because the difference in temperature is great between looped netowrk cabinet top and the hot-air to air humidity is great again, and looped netowrk cabinet top still can dewfall, and dew can accumulate gradually and the problem that the salt of mixed air shunts to the equipment makes the equipment short circuit in the looped netowrk cabinet break down.
Description
Technical Field
The utility model relates to an electric power facility field especially relates to an open electric power facility of no consumption prevents dew structure.
Background
Open-air electric power facility is like the looped netowrk cabinet, owing to place in open-air environment, and open-air environment humiture constantly changes great, and when outside temperature was colder, looped netowrk cabinet internal plant was because the electric current through generating heat the inside air, when hot-air met cold looped netowrk cabinet wall, because the temperature is less than its dew point and leads to the inside dewfall of looped netowrk cabinet, and dew accumulation and mixed air's salt shunts the equipment and makes the equipment short circuit in the looped netowrk cabinet break down. To solve this problem, the prior art is to provide upper convection holes and lower convection holes at the upper and lower parts of the ring main unit. When the ring main unit is in work, the equipment in the ring main unit heats the air in the ring main unit through current, the air is heated and rises and is discharged through the upper convection hole, the air pressure at the lower part of the ring main unit is smaller than the external air pressure due to the loss of the air in the ring main unit, the external cold air enters the ring main unit through the lower convection hole, the heat of the equipment in the ring main unit is ingeniously utilized to enable the air in the ring main unit to form convection, and therefore the purpose of preventing the condensation inside the ring main unit is achieved by reducing the temperature of the air in the ring main unit. However, the ring main unit has the problems that when the outside temperature is relatively cold and the air humidity is relatively high, heated air in the ring main unit is heated to rise and meets the cold ring main unit top, the ring main unit top still can dew due to the large temperature difference between the ring main unit top and hot air and the relatively high air humidity, and the dew can be gradually accumulated and the salt mixed with the air is shunted to equipment due to the flat top of the ring main unit top, so that the equipment in the ring main unit is short-circuited and breaks down.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: an anti-dew structure of an open-air power facility without power consumption is provided to solve the above problems.
The technical scheme of the utility model is that: an anti-dew structure of a non-power-consumption open-air power facility,
