Abstract
The invention provides the electric power cabinet of a kind of moisture proof electric leakage, comprise the shell be made up of metallic plate, also comprise the inner casing that one deck is made up of heat-insulating shield inside described shell, described inner housing surface is covered with through hole; To be separated by between described shell and inner casing 3mm ~ 5mm; Connected as one by link between described shell and inner casing; The through-hole aperture of described inner housing surface is 2mm ~ 3mm; Various power components can not only be stopped, prevent them from passing through hole, turn avoid capillary effect, prevent the water droplet on outer casing inner wall to be sucked.This electric power cabinet when electric power cabinet internal-external temperature difference is larger, can prevents internal power parts from making moist, thus avoids the potential safety hazards such as electric leakage.
Description
Technical field
The present invention relates to electric power facility field, especially, relate to a kind of electric power cabinet.
Background technology
Electric power cabinet is a kind of conventional power infrastructures, and a large amount of power components is equipped with in its inside, and therefore, its protective requires higher; And current electric power cabinet, surround primarily of shell, shell is one deck iron sheet, although can play good protective action to inner power components, Problems existing is, when the temperature of the surroundings is low, especially autumn and winter season, because electric power cabinet internal-external temperature difference is comparatively large, the inwall of shell will produce condensate, and this kind of condensate causes potential safety hazard to the power components of electric power cabinet inside.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide the electric power cabinet that a kind of moisture proof is leaked electricity, this electric power cabinet when electric power cabinet internal-external temperature difference is larger, can prevents internal power parts from making moist, thus avoids the potential safety hazards such as electric leakage.
The technical scheme that technical solution problem of the present invention adopts is: the electric power cabinet of this moisture proof electric leakage comprises the shell be made up of metallic plate, and also comprise the inner casing that one deck is made up of heat-insulating shield inside described shell, described inner housing surface is covered with through hole; To be separated by between described shell and inner casing 3mm ~ 5mm; Connected as one by link between described shell and inner casing.
As preferably, the through-hole aperture of described inner housing surface is 2mm ~ 3mm; Various power components can not only be stopped, prevent them from passing through hole, turn avoid capillary effect, prevent the water droplet on outer casing inner wall to be sucked.
As preferably, described heat-insulating shield is made up of PVC board; There is suitable intensity; Further, described PVC board is transparent panel, and convex lens array is made on its surface; This makes the thermal radiation of electric power cabinet inside, can through inner casing, act on a series of array points of outer casing inner wall, make these array point local fast heatings, thus by the liquid pearl rapid evaporation on each array point, this makes the whole surface being covered with liquid pearl of outer casing inner wall produce disturbance, and then impels the whole surface being covered with liquid pearl to evaporate rapidly.
As preferably, described link is be welded in the bonding jumper on described outer casing inner wall, realizes the connection to shell and inner casing by the mode of the groove embedding described inner casing outer wall.
Beneficial effect of the present invention is: the electric power cabinet of this moisture proof electric leakage in use, when electric power cabinet internal-external temperature difference is larger, the surface of described shell must be in comparatively cold state, this through hole making the hot-air of electric power cabinet inside pass described inner housing surface moves to the inwall of shell, thus meet cold liquefaction at the inwall of shell, form liquid pearl, this kind of liquid pearl diameter is less, is just isolated in the hollow sandwich between described shell and inner casing; Thus avoid the contact of internal power parts and liquid pearl, eliminate the potential safety hazards such as electric leakage.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the electric power cabinet of this moisture proof electric leakage.
Fig. 2 is an embodiment schematic diagram of inner casing in the electric power cabinet of this moisture proof electric leakage.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1, embodiment illustrated in fig. 2 in, this moisture proof electric leakage electric power cabinet comprise the shell 1 be made up of metallic plate, also comprise the inner casing 2 that one deck is made up of heat-insulating shield inside described shell 1, described inner casing 2 surface is covered with through hole 200; To be separated by between described shell 1 and inner casing 2 3mm ~ 5mm, namely to there is between shell 1, inner casing 2 hollow sandwich 3 that a width is 3mm ~ 5mm; Connected as one by link 4 between described shell 1 and inner casing 2.
The electric power cabinet of above-mentioned moisture proof electric leakage, through hole 200 aperture on described inner casing 2 surface is 2mm ~ 3mm; Various power components can not only be stopped, prevent them from passing through hole 200, turn avoid capillary effect, prevent the water droplet on shell 1 inwall to be sucked; Described heat-insulating shield is made up of PVC board, has suitable intensity; Further, described PVC board is transparent panel, and as shown in Figure 2, convex lens 20 array is made on its surface; This makes the thermal radiation of electric power cabinet inside, can through inner casing 2, act on a series of array points of shell 1 inwall, make these array point local fast heatings, thus by the liquid pearl rapid evaporation on each array point, this makes the whole surface being covered with liquid pearl of outer casing inner wall produce disturbance, and then impels the whole surface being covered with liquid pearl to evaporate rapidly.
The electric power cabinet of above-mentioned moisture proof electric leakage, described link 4, for being welded in the bonding jumper on described shell 1 inwall, realizes the connection to shell 1 and inner casing 2 by the mode of the groove embedding described inner casing 2 outer wall.
The electric power cabinet of above-mentioned moisture proof electric leakage in use, when electric power cabinet internal-external temperature difference is larger, the surface of described shell 1 must be in comparatively cold state, this through hole making the hot-air of electric power cabinet inside pass described inner casing 2 surface moves to the inwall of shell 1, thus meet cold liquefaction at the inwall of shell 1, form liquid pearl, this kind of liquid pearl diameter is less, is just isolated in the hollow sandwich 3 between described shell 1 and inner casing 2; Thus avoid the contact of internal power parts and liquid pearl, eliminate the potential safety hazards such as electric leakage.
The foregoing is only preferred mode of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
