Abstract
The utility model relates to a ventilating and dust-preventing high-voltage cable branch box shell. The shell comprises a box body (1), a box pedestal (2), a lock box (3) and box doors (4), and is characterized in that the box doors (4) are disposed in front and at back of the box body (1), are in an inverted trapezoid shape and are mounted on the box body (1) through hinges (5), withdrawal-type support rods (6) are disposed between the box doors (4) and the box body (1), the box pedestal (2) is communicated with the box body (2),outer heat dissipation holes (7) are disposed on the two sides of the box pedestal (2), inner heat dissipation holes (8) are arranged with respective to the outer heat dissipation holes (7), a dust preventing net (9) is arranged between the outer heat dissipation holes (7) and the inner heat dissipation holes (8), and the outer heat dissipation holes (7) incline downwards at 45 degrees while the inner heat dissipation holes (8) incline upwards at 45 degrees. The high-voltage cable branch box shell is unobstructed in ventilation, and can maintain the air in the box body to be dry and effectively prevent rainwater and dust from entering into the box body.
Description
Technical field
The utility model belongs to high voltage cable branch box housing technologies field, relates in particular to a kind of high voltage cable branch box housing that is provided with dust control by ventilation that is applicable to electric power system in each electric company business district.
Background technology
At present, domestic high voltage cable branch box housing draft type is to utilize to carry out ventilation and heat in the louver-type ventilation hole of feeder pillar housing base both sides.Because feeder pillar housing is to use out of doors, such ventilation hole weather muddy water and be easily splashed into box house.Under dry climatic condition, while blowing, again dust is blown in case, make for a long time institute in casing increase by electric components accumulation dust, add and be provided with design casing overdraught hole, make air-flow in casing can not form circulation, run into humid conditions and high-voltage electrical apparatus part easily occurs discharge over the ground, burn electric component and cause power outage.
Summary of the invention
The purpose of this utility model, in order to overcome above-mentioned drawback, provides one can make to keep ventilation in casing, makes air natural circulation in case, keeps air in casing to be dried, and can effectively prevent that again rainwater, dust from entering the dust control by ventilation high voltage cable branch box body of casing.Realizing the technical scheme that originally practical object is taked is: a kind of dust control by ventilation high voltage cable branch box body, include casing, case base, lock box and chamber door, it is characterized in that: described chamber door divides the front and back that are located at casing, chamber door is inverted trapezoidal shape, be arranged on casing by hinge, between chamber door and casing, be provided with drawing and pulling type support bar, support after being used for starting chamber door.Described case base and casing are connected together, and the both sides of case base arrange respectively outside louvre, and outside louvre arranges inner side louvre relatively, and between outside louvre and inner side louvre, Air Filter is set.Described outside louvre is spent to declivity 45, upward 45 degree of inner side louvre.Both made rain splash on casing, and also can, at rainwater gravity with under the effect of declivity miter angle, make the quick landing of rainwater, and the louvres of the upward 45 degree designs in inner side can prevent that rainwater from splashing in casing.Thereby reach effect rainproof, dustproof, that ventilate.
The utility model provides one can make the interior ventilation of case shell unobstructed, makes to produce air natural circulation in case, and the interior air of maintenance casing is dry, can effectively prevent that again rainwater, dust from entering the high voltage cable branch box of the draft type in casing.
