The utility model discloses it is outdoor with low voltage distribution box top waterproof construction protection level IP44's requirement has been reached to the outer shell protection grade that makes its top rises to IP45 by IP44, the fully provided it is outdoor with low voltage distribution box top waterproof construction's needs.
Description
Technical field
The utility model belongs to power system city net, the structure design of rural power grids distributed board outdoor and manufacturing field of equipment, tool
Body is related to a kind of outdoor low-voltage distribution box top waterproof construction.
Background technology
Outdoor distribution box by extensive substantial amounts of use in city net, the end of rural power grids outdoor electricity distribution, due to using for open air,
Therefore the technical requirements of the shell protection grade of distributed board outdoor are IP44.
Existing distributed board outdoor top structure is generally completed in the form of top with welding box body or assembling.Its top structure
In order to reach the purpose of ventilation and heat, mostly there is ventilation and heat slotted eye using the lower edge punching in top surrounding, in the top of slotted eye
Press-fiting or being welded has<The stainless steel cloth of 40 mesh, to prevent>1 object or little echiuran are entered in distribution box.So can reach
The degree of protection of IP40.But it is not tight enough into measure that all directions are prevented from dabbling, it is difficult to reaches the degree of protection requirement of IP40.
Due to case top and casing be plane to flat face, be either welded or assemble, all can not prevent from peripheral direction
Dabble and flowed in distribution box into joint gap, if current shower water from below, water column also can be entered by the space of silk screen
Enter casing, it is impossible to meet the waterproof requirement of shell protection grade IP44, if current overflow into casing, distribution box will be caused in work
The generation of dangerous accident when making state.Solve the waterproof technique requirement of distributed board outdoor, the top structure and case of distribution box
Body structural attachments make that waterproof construction is processed and design is a crucial technical problem that distributed board outdoor must be solved.
The content of the invention
It is to overcome problem of the prior art that the purpose of this utility model is, there is provided outdoor low-voltage distribution box top waterproof
Structure.
Outdoor low-voltage distribution box top waterproof construction of the present utility model, including distributing box and sunk type top cover, institute
State distributing box upper end and be provided with interior bending plane, the interior bending plane is connected with sunk type top cover by fixedly connected part, institute
State fixedly connected part junction and be provided with waterproof washer, the sunk type top cover includes sunk unit and cover unit, the sinking
The bottom surface of unit is provided with louvre, and the louvre is provided with insect prevention silk screen, in the sunk type top cover water fender is provided with, described
Water fender leaves space, the gear located at louvre or insect prevention silk screen top, the water fender with the medial surface of sunk type top cover
Water plate is installed in interior bending plane by fixedly connected part, and the interior bending plane has upwardly extended dash flange.
Used as further improvement of the utility model, the water fender forms the folder of 5-85 degree with insect prevention silk screen or louvre
Angle.
Used as further improvement of the utility model, the fixedly connected part includes blind nut and fixing bolt, described
Water fender is fixedly installed in casing upper end in bending plane by blind nut and fixing bolt, fixing bolt and casing it
Between be provided with waterproof washer.
The utility model compared with prior art, with advantages below：
Adopt between the sunk type top cover and distributing box of outdoor low-voltage distribution box top waterproof construction of the present utility model
Installed with sunk type, top cover sinks installed in the surrounding of distributing box, the installation of distributing box upper end is provided with reference to the interior edge on side
Dash flange with angle, the dash flange is placed in the surrounding on edge in distributing box upper end, and is provided with phase at top cover lower edge edge
Should the water fender with angle, the top of water fender and lid periphery inner side are left>10 air channel, so that outer gas stream passes through silk screen
After aperture enters, cartonning top is entered in the gap along between water fender and inside of top cover, plays a part of to reduce temperature rise.Conversely, matching somebody with somebody
Thermal current produced by electric box house components and parts also can be flowed out by the silk screen hole of surrounding, and equally playing reduces the work of temperature rise
With.
Even if enter top cover by silk screen hole from dabbling or spraying water for bottom entrance, also can be blocked by water fender and must not be entered
Enter inside distributing box.If to dabble enter fashionable along surrounding lower edge edge gap with shower water, when current enter top cover and match somebody with somebody
The faying face of electronic box body, the water for overflowing into also can be blocked by dash flange, not entered inside distributing box.Hard-wired bolt
Waterproof washer is added between blind nut, water also can permeate distributing box.Due in distributing box and top cover faying face
Surrounding is provided with dash flange, the inner side edge surrounding that top cover lower edge is installed is provided with water fender, hard-wired blind nut
Waterproof washer is added between bolt, is dabbled with shower water in distributing box so as to be effectively prevented all directions
Portion, has reached the requirement of outdoor low-voltage distribution box top waterproof construction degree of protection IP44, and makes the shell protection at the top of it
Grade is lifted to IP45 by IP44, fully meets the needs of outdoor low-voltage distribution box top waterproof construction.
