Description

Aeration type power distribution cabinet
Technical field
The utility model is related to power distribution cabinet more particularly to a kind of aeration type power distribution cabinets.
Background technology
Power distribution cabinet(Case)Sub-power power distribution cabinet(Case)And light distribution cabinet(Case), metering cabinet(Case), it is the end of distribution system Grade equipment.Power distribution cabinet is the general designation of motor control center.Power distribution cabinet is used in the occasion that load is more dispersed, circuit is less; The occasion that motor control center concentrates for load, circuit is more.Their electric energy a certain circuit of upper level controller switching equipment Distribute to load nearby.This grade of equipment reply load provides protection, monitoring and control.The use that power distribution cabinet has indoors, has Use in outdoor, use and outdoor be known as outdoor queuing cabinet.The use of outdoor electricity distribution cabinet is equipped with claimed below:There is rain-proof Snow measure;If fence will have ground protection to arrange;Moisture-proof, power distribution cabinet lower margin is higher than ground not less than 20 centimetres and is laid with plank It is not less than 1.2 meters far from ground as insulation, power distribution cabinet bottom;It will there are the operating spaces not less than 70 centimetres before and after power distribution cabinet; The mark that Danger is equipped with outside fence.Existing outdoor electricity distribution cabinet matching has the following disadvantages:Air flow property is poor, cannot It is enough that easily heat loss is gone out.
Utility model content
The utility model is intended to provide a kind of aeration type power distribution cabinet that air circulation is good, empty to solve existing power distribution cabinet The problem of influence heat dissipation effect caused by air-flow general character difference.
The above technical problem is solved by following technical proposal:A kind of aeration type power distribution cabinet, including cabinet, the cabinet Body includes cabinet side wall and cabinet roof, which is characterized in that the cabinet roof is equipped with the cornice for stretching out the cabinet side wall, institute The lower end for stating cabinet side wall is equipped with several air inlet holes, upper end is equipped with several exhaust vents, and the air inlet hole is the upward inclined hole in inner end, The exhaust vent is the upward inclined hole in outer end, and the opening direction line of the exhaust vent intersects with the cornice.Setting disengaging air holes, It can improve in power distribution cabinet that air is with the runner patency between exterior space, consequently facilitating heat sheds.Air inlet is with outer end Interior high mode tilts, and rainwater can be effectively prevent to enter through air inlet.The angle of inclination of air inlet hole is more than 30 °, and then effect is more It is good.Cornice are set and make the opening of exhaust vent towards cornice, the probability that rainwater enters through exhaust vent in power distribution cabinet can be reduced.
Preferably, the inner surface of the cabinet side wall be equipped with it is several correspondingly with the air inlet hole alignment in Portion's protrusion, the air inlet hole penetrate through the internal protrusion.The depth of air inlet hole can be improved in the case where cabinet side wall is relatively thin, To improve the effect for preventing rainwater from entering.
Preferably, the external port of the exhaust vent invests the projection whole position of cornice along exhaust vent opening direction line direction In on the cornice.Prevent the effect that rainwater enters through exhaust vent good.
Preferably, the outer surface of the cabinet side wall be equipped with it is several correspondingly with the outer of exhaust vent alignment Portion's protrusion, the exhaust vent penetrate through the outer projection.It can prevent the rainwater to flow down through cabinet side wall from entering through exhaust vent.
Preferably, the free end end face of the outer projection is the inclination tilted down, described in the exhaust vent perforation The free end end face of outer projection.Rain can be prevented from the effect entered in power distribution cabinet.
The utility model tool has the advantage that:Air circulation is good, sheds convenient for heat;Rainwater does not allow The book of Changes inlet and outlet Into inside cabinet.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
In figure:Cabinet 1, cabinet side wall 11, cabinet roof 12, cornice 15, shutter 2, shutter lower surface 21, block It is the upper surface 22 of plate, pull rod 23, air inlet hole 3, internal protrusion 31, exhaust vent 4, outer projection 41, the external port of exhaust vent 42, outer The free end end face 43 of portion's protrusion.
Specific implementation mode
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of aeration type power distribution cabinet, including cabinet 1.Cabinet 1 includes cabinet side wall 11 and cabinet roof 12.Cabinet Four sides all around of body roof 12 are designed with the cornice 15 for stretching out cabinet side wall 1.The lower end of cabinet side wall 11 is equipped with 3 rows along upper The air inlet hole 3 of lower directional spreding.The upper end of cabinet side wall 11 is equipped with a discharge air holes 4.The inner surface of cabinet side wall 11 is equipped with Several internal protrusions 31 being aligned correspondingly with air inlet hole.Air inlet hole 3 is the upward inclined hole in inner end.Internal protrusion 31 is to incline Biassed fabric.The inclined direction of internal protrusion 31 is identical with the inclined direction of air inlet hole 3.Air inlet hole 3 penetrates through internal protrusion 31.
Exhaust vent 4 is the upward inclined hole in outer end.The outer surface of cabinet side wall 11 is equipped with several correspondingly with described The outer projection 41 of exhaust vent alignment.The inclined direction of outer projection 41 is identical with the inclined direction of exhaust vent 4.Exhaust vent 4 passes through Logical outer projection 41.The opening direction line namely center line of exhaust vent 4 intersect with cornice 15.The external port 42 of exhaust vent is along outlet air The projection of hole opening direction line direction trend of purchasing cornice is all on the cornice 15.The free end end face 43 of outer projection is to dip down Oblique inclination.Exhaust vent 4 penetrates through the free end end face 43 of outer projection.
