Abstract
The utility model discloses a ventilation port structure of a metal enclosed switch device, and belongs to the technical field of a ventilation port structure. The ventilation port structure comprisesa heat radiating meshed plate and metal reinforced bending plates and is characterized in that the heat radiating meshed plate is in the shape of a plurality of W which are connected; and the metal reinforced bending plates are welded at two ends of the heat radiating meshed plate. The scope of an inclination angle on the heat radiating meshed plate is 20-60 degrees. The utility model has the advantages of wide application range and simpler structure and can improve the device under the situation of not changing the prior structure of the metal enclosed switch device and further improve the ventilation and heat radiation capability of the metal enclosed switch device through mounting the device.
Description
Technical field
The utility model relates to a kind of ventilating opening structure, particularly relates to a kind of ventilating opening structure of metal enclosed switchgear.
Background technology
Metal enclosed switchgear is except that the outside connects, and all the interior switchgear of metal shell of ground connection is finished and is enclosed in assembling.Shell need provide the degree of protection of regulation as the part of metal enclosed switchgear, with the protection internal unit be not subjected to ectocine, prevent personnel near or touch live part, the personnel of preventing touch motion parts.Simultaneously,, must in the structure of metal enclosed switchgear, be furnished with vent passages and ventilating opening, to play the effect of ventilation, heat radiation for the temperature rise that can make metal enclosed switchgear inside reaches the regulation requirement.After operation a period of time, because easy laying dust, but its draught capacity can descend the metal enclosed switchgear of conventional flat ventilating opening structure to some extent usually.Metal enclosed switchgear is because the restriction of structure and overall dimension, the possibility of the essentially no change of size of its vent passages and ventilating opening, so need a kind of ventilating opening structure of design, make it under the prerequisite of not changing vent passages and ventilating opening size, can further promote ventilation, the heat-sinking capability of metal enclosed switchgear.
Summary of the invention
At the problems referred to above, it is a kind of under the prerequisite of not changing vent passages and ventilating opening size that main purpose of the present utility model is to provide, can further promote the ventilation of metal enclosed switchgear, the ventilating opening structure of heat-sinking capability, the utility model solves above-mentioned technical problem by following technical proposals: a kind of ventilating opening structure of metal enclosed switchgear, it comprises: comprise heat radiation web plate and metal reinforcement bent plate, it is characterized in that: described heat radiation web plate presents the shape that some " W " connect together, and described metal is strengthened the two ends that bent plate is welded on described heat radiation web plate.
Wherein, the inclination angle scope on the described heat radiation web plate is the 20-60 degree.
Wherein, the inclination angle on the described heat radiation web plate is 30 degree.
Positive progressive effect of the present utility model is: the utlity model has following advantage:
The ventilating opening structure of the utility model metal enclosed switchgear is applied widely, structure is comparatively simple and direct, this device of repacking under the original structure situation of metal enclosed switchgear can not changed, by this Unit Installation, can further promote the ventilation and the heat-sinking capability of metal enclosed switchgear.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the heat radiation schematic diagram of the conventional ventilating opening of metal enclosed switchgear;
Fig. 2 is the heat radiation schematic diagram of the utility model metal enclosed switchgear ventilating opening;
Fig. 3 is the structural representation of the utility model metal enclosed switchgear ventilating opening.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is the heat radiation schematic diagram of the conventional ventilating opening of metal enclosed switchgear, and its ventilating opening is flat ventilating opening structure form, and the efficiently radiates heat surface area is I, and common heat radiation web plate 11 upper surfaces gather various dust quite easily, thereby influence its radiating effect;
Fig. 2 is the heat radiation schematic diagram of the utility model metal enclosed switchgear ventilating opening, the heat radiation web plate 21 that improves after designing passes through flanging technology, be processed into the corrugated with 30 ° of inclination angles, the possibility that heat radiation web plate 21 surperficial various dust gather can be fundamentally eliminated in its inclination angle design; The efficiently radiates heat surface area III of web plate 21 of dispelling the heat simultaneously compares flat efficiently radiates heat surface area I structure and has improved 3～4 times; After the web plate 21 that will dispel the heat was processed into corrugated, its hot-air that converges in heat radiation web plate 21 tops can be more convenient entered into metal enclosed switchgear air outside convection current II, played a positive role for the heat radiation of metal enclosed switchgear inside.
Fig. 3 is the structural representation of the utility model metal enclosed switchgear ventilating opening, the two ends of heat radiation web plate 21 and metal are strengthened bent plate 31 and are assembled into an integral body by welding procedure, this overall structure form can guarantee that the heat radiation web plate behind the flanging has good mechanical strength, can the distortion easily because of some external force effect.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
