Abstract

The invention provides an outdoor anti-condensation control cabinet comprising a top shed which is arranged on a cabinet body, the cabinet body and ventilation windows which are arranged on two sides of the cabinet body. The bottom part of the cabinet body is provided with a heating device. The top shed adopts a double-layered top shed structure, wherein an upper top shed adopts a heat insulation material inclined top structure, and a lower top shed adopts a grid structure. The cabinet body is externally painted with light color scheme paint, and the internal wall is coated with paint with high hydrophobicity. The ventilation windows arranged on the two sides of the cabinet body are vertically arranged, and ventilation openings are provided with filter screens. The heating device adopts a constant heating type low-power heating element. Besides, a disconnection and shorting alarm device is installed. The control cabinet can withstand outdoor natural environment effects like sunshine, rain, snow, etc. A hot-pressing natural ventilation method is adopted, and a heater is arranged inside the control cabinet so that air temperature inside the cabinet is enhanced. Meanwhile, natural ventilation is additionally supplemented and external dry air is led into the cabinet so that air humidity inside the cabinet is reduced, condensation is avoided and electrical elements inside the cabinet are protected.

Description

The anti-condensation control cubicle in a kind of open air
Technical field
The present invention relates to a kind of control cubicle, the anti-condensation control cubicle in especially a kind of open air.
Background technology
For equipment such as the primary cut-out of open air operation, combined electrical apparatuses, its on-site control can produce condensation because of reasons such as outdoor environment are moist, variations in temperature is large, and then cause damage, the terminal board short circuit of secondary component in cabinet, the problems such as corrosion of the steel components of control cubicle own, thereby the safe operation of main equipment is produced to hidden danger.
201220250203.2 1 kinds of anti-condensation switch cubicles of prior art Patent application number, it is provided with discharge window in cabinet side, and hot-air is toward rising with steam, then on cabinet top, condense, so can not be not very good in top design condensation-preventing device effect.
Summary of the invention
For solving condensation problem, the invention provides the anti-condensation control cubicle in a kind of open air, adopt Thermal Natural Ventilation method, heater is set in control cubicle to improve air themperature in cabinet, be aided with natural draft imports outside dry air in cabinet simultaneously, thereby air humidity in reduction cabinet, avoids the generation of condensation.
The anti-condensation control cubicle in a kind of open air of the present invention, comprising: be contained in ceiling, the cabinet above cabinet and be arranged on the ventilation window of cabinet both sides, described bottom of cabinet bulk is provided with heater.
Described ceiling adopts double-deck ceiling structure.
Upper ceiling in described double-deck ceiling adopts ramp-roof structure, and lower ceiling adopts grid mechanism.
Described upper ceiling adopts heat-barrier material.
Described cabinet is brushed light color system paint outward.
Described cabinet inwall selects the coating with high hydrophobic to carry out application.
The ventilation window of described cabinet both sides, adopts up and down and arranges, at ventilating opening, filter screen is housed.
Described heater adopts normal pattern of fever low-power heater element.
Described heater is provided with broken string, short-circuit alarming device.
The invention has the beneficial effects as follows: 1) control cubicle ceiling adopts inclination angle design can make the condensation forming along cabinet top, slide under the effect of gravity, and can not be dropped in cabinet on secondary component, the while can also prevent that outside sleet is deposited on top cover; 2) cabinet painting color should adopt the lower light color of radiation coefficient system as far as possible, and the absorption of heat, reduces the inside and outside temperature difference of control cubicle when reducing direct sunlight; 3) discharge window is setting up and down, strengthens circulation of air; 4) air in heater appropriate heating cabinet, can strengthen the hygroscopic capacity of air, improves the aridity in cabinet, reduces the possibility that condensation occurs.5) heater adopts uninterrupted operation method, and sample has reduced relevant control element, has improved reliability of operation.
Accompanying drawing explanation
Fig. 1 control cubicle structural representation;
Reference numeral 1-ceiling, the upper ceiling of 11-, ceiling under 12-, 2-cabinet, 3-ventilation window, 4-heater.
Embodiment
An anti-condensation control cubicle as shown in Figure 1, comprising: be contained in ceiling 1, the cabinet 2 above cabinet and be arranged on the ventilation window 3 of cabinet both sides, described bottom of cabinet bulk is provided with heater 4.
Owing to being outdoor control cubicle, requirement can stand the such environmental effects such as Exposure to Sunlight, sleet, and ceiling 1 adopts inclination angle design.Because the condensation in control cubicle often occurs in top board place, therefore upper ceiling 11 adopts inclination angle design can make the condensation forming along cabinet top, slide under the effect of gravity, and can not be dropped in cabinet on secondary component, can also prevent that outside sleet is deposited on top cover simultaneously.And upper top 11 adopts heat-barrier material, reduces the heat that conducts to cabinet inside along top cover, reduces the possibility that condensation produces.Lower ceiling 12 adopts cell structure ventilated, is convenient to hot-air in cabinet and distributes from top with steam.
Cabinet 2 paint are considered solar light irradiation, the cabinet surface painting color temperature difference inside and outside to control cubicle is directly proportional, therefore painting color should adopt the light color system that radiation coefficient is lower as far as possible, and the absorption of heat, reduces the inside and outside temperature difference of control cubicle when reducing direct sunlight.Cabinet inwall selects the coating with high hydrophobic to carry out application in addition, and the globule that dewfall is formed is difficult for adhering to inwall.
Ventilation window 3 on cabinet, adopts up and down and arranges, curve is as shown in Figure 1 cabinet inner air flow route, and the larger ventilation effect of difference in height is better, and at ventilating opening, filter screen is housed and prevents that the foreign material such as dust, insect from entering.
At the bottom of cabinet, heater 4 adopts normal pattern of fever low-power heater element, and during its operation, surface temperature should not be over 80 ℃.Utilize air in heater appropriate heating cabinet, can strengthen the hygroscopic capacity of air, improve the aridity in cabinet, reduce the possibility that condensation occurs.Heater should adopt uninterrupted operation method, has reduced so relevant control element, has improved reliability of operation.Heater is provided with broken string, short-circuit alarming device, to prevent due to the unexpected generation that causes condensation phenomenon out of service of heater.
