Abstract
The invention discloses a ventilation base of a cable distribution box. The ventilation base is formed by combining four supporting frames which are parallel in pairs, wherein each supporting frame is a rectangular frame formed by combining four rigid components which are parallel in pairs, a ventilation panel is fixed in each rectangular frame, ventilation holes are formed in the ventilation panels, and the area of the ventilation holes in each ventilation panel accounts for 40-60% of the total area of the ventilation panel. The ventilation base adopts an open type natural ventilation method, uses angle iron as the supporting frames, has wider choice in materials of the ventilation panels, is low in fabrication cost, convenient in installation and reliable in operation, greatly reduces the humidity when compared with an old cable distribution box through field installation and test, and does not cause the phenomenon of short circuit and tripping in summer due to high humidity.
Description
Technical field
The present invention relates to transmission line of electricity auxiliary equipment, more particularly to a kind of cable distribution box ventilation base.
Background technology
In recent years, with China's urban construction and transformation, increasing transmission line of electricity is realized putting cable underground.However,
Find that the tripping times of cable run are more during use, summer is particularly evident, and after testing, trip reason is cable distribution box
Interior humidity is too high, and forming the globule after moisture cooling is attached on end, sleeve pipe and other charging equipments, causes short-circuit jump
Lock.A kind of metal outdoor box with aeration structure becomes disclosed in Chinese patent 2009200681765, and it is opened on ventilation base
, to improve ventilation condition, but because its support frame is excessively complicated, and the number of openings is less, causes ventilation effect not good for circular hole,
In addition in order to increase ventilation, by aperture do it is larger, often have toy from hole enter distribution box bottom, to distribution box bottom
Cable constitutes potential safety hazard.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of cable distribution box ventilation base.
The technical solution adopted by the present invention is：A kind of cable distribution box ventilation base, by four carriages parallel two-by-two
Frame combination is constituted, it is characterized in that：The support frame is to combine the rectangular frame for constituting by four parallel two-by-two rigid components,
Ventilation front plate is fixed with the rectangular frame, air vent, air vent in the ventilation front plate are provided with the ventilation front plate
Area accounts for the 40-60% of the ventilation front plate gross area.
Described cable distribution box ventilation base, it is characterized in that the air vent is long circular hole, its length-width ratio is 80：9,
Distance is wide 0.9-1.1 times in hole between adjacent air vent.
The present invention uses open natural ventilating method, it is adaptable to Arid Area.The present invention uses angle bar as carriage
Frame, the materials of ventilation front plate are more wide in range, low manufacture cost, easy for installation, reliable, right by installing experiment on the spot
Than old-fashioned cable distribution box, humidity is substantially reduced, the phenomenon that the short circuit tripping operation because of high humidity does not occur in summer.Air vent is adopted
Designed with elongated hole, draught area can be greatly increased, it is ensured that ventilation effect.By prolonged research and practice, when air vent is long
80mm, 9mm wide, when pitch of holes is 5mm, while ensure that draught area, make ventilation front plate have enough intensity, divulge information
Small-sized biological is not easily accessible in base, it is ensured that ventilation base long-time steady operation.
Brief description of the drawings
Fig. 1 is top view of the present invention；
Fig. 2 is front view of the present invention；
Fig. 3 is present invention transverse direction angle bar and solebar angle attachment structure schematic diagram.
In figure：1- support frames, 2- ventilation front plates, 3- air vents, 11- transverse direction angle bar, 12- solebar angles.
Specific embodiment
Embodiment one：
As shown in Figure 1-2, cable distribution box ventilation base of the invention is that top view is a rectangular frame, and cable distribution box is put
In on the rectangular frame.The rectangular frame is formed by fixedly connecting by four support frames 1 parallel two-by-two.The support frame 1 is then
It is to be formed by fixedly connecting by four rigid components such as angle bar or similar component are parallel two-by-two, it is shaped as rectangle, solid in framework
Surely there is ventilation front plate 2.Air vent 3 is formed with ventilation front plate.Above-mentioned ventilation front plate can use iron sheet or organic material.
Shown in Fig. 3, the rectangular frame of ventilation base is made up of four support frames 1, and adjacent the two of four support frames
Individual framework can share a solebar angle, and thus, whole base rectangular frame is to include 8 horizontal angle bar 11 and 4 longitudinal angles
Iron 12,12 liang of right-angle surface upper and lower sides of solebar angle connect a horizontal horizontal angle bar of 11,8, angle bar and set relatively up and down two-by-two respectively
Put, bolts at two ends is fixed on solebar angle 12, so as to form rectangular frame structure, solebar angle 12 plays connection and props up simultaneously
Support is acted on, and ventilation front plate 2 is fixed between two horizontal angle bar, and air vent 3 is set on ventilation front plate, and air vent 3 is oval
Hole, and length-width ratio is 80：9, air vent 3 is longitudinally disposed, arranged in parallel, and the area of air vent 3 accounts for the 40- of the ventilation front plate gross area
60%, two adjacent ventilation pitchs of holes are to divulge information 0.9-1.1 times of hole width.
Embodiment two：
As shown in Figure 1-2, a kind of cable distribution box ventilation base, including support frame 1 and ventilation front plate 2.As shown in Figure 2,3,
Support frame 1 includes 8 horizontal angle bar 11 and 4 solebar angles 12, and 12 liang of right-angle surface upper and lower sides of solebar angle connect one respectively
11,8, root transverse direction angle bar is horizontal, and angle bar is oppositely arranged up and down two-by-two, bolts at two ends is fixed on solebar angle 12, so as to be formed
Rectangular frame structure, solebar angle 12 plays connection and supporting role simultaneously, and ventilation front plate 2 is arranged at relative horizontal angle bar
Between, air vent 3 is set on ventilation front plate 2, air vent 3 is elongated hole, and 80mm long, 9mm wide, air vent 3 is longitudinally disposed, level
Arrangement, adjacent ventilation pitch of holes is 5mm, and the area of air vent 3 accounts for the 60% of rectangular frame lateralarea.
In above-described embodiment, ventilation front plate can be used the Metal Material Weldings such as iron plate in support frame, also can be used non-
Metal material such as plastics, are connected by modes such as adhesion or buckles.
When using, ventilation base makes cable box inner ventilation, and especially the ventilation effect of bottom more preferably, makes in cable shaft
Moisture had been drained off before distribution box is entered, so as to ensure the drying inside distribution box to the full extent.
