Abstract
The utility model belongs to switch cubicle technical field, relate to low voltage drawing-out switching carbinet specifically, its technical characteristics is: comprise the cabinet be made up of switch drawer room and cable vault, described switch drawer indoor are provided with multiple vertically disposed switch drawer, in the upper end of described cabinet lower end and cabinet side with ventilation hole, described ventilation hole is " S " type.When the strip foreign material such as paper scrap, leaf or petiole by wind to ventilation hole time, because ventilation hole is " S " type, ventilation hole edge by foreign material gear outside cabinet, avoid paper scrap, leaf or petiole strip foreign material and enter in switch cabinet.Make low voltage drawing-out switching carbinet can be applicable to various environment, and greatly extend in useful life.
Description
Technical field
The utility model belongs to switch cubicle technical field, particularly relates to low voltage drawing-out switching carbinet.
Background technology
For the electricity market that meets development increase-volume, computer interface, power concentration are controlled, easy to installation and maintenance, shorten the needs such as accident treatment time, low voltage drawing-out switching carbinet is widely used.In order to reduce the heat that components and parts in use produce, below low voltage drawing-out switching carbinet, be provided with ventilation hole.The ventilation hole of current switch cubicle is rectangle.There is following defect in the ventilation hole of above-mentioned shape: one, and because switch cubicle is by surrounding environment influence, while air intake, the strip foreign material such as the paper scrap in air, little leaf, petiole easily enter in switch cubicle, causes the situations such as short circuit to occur; Its two, the dust in air easily enters in switch cubicle, causes corrosion to the components and parts in switch cubicle; Its three, the ventilation hole of rectangle also can cause panel impact strength to reduce.
Utility model content
The technical problem of solution of the present utility model is just to provide the low voltage drawing-out switching carbinet that a kind of ventilation effect is good, excellent in cushion effect, can effectively prevent the strip foreign material such as paper scrap, leaf and petiole from entering.
The technical solution adopted in the utility model is: comprise the cabinet be made up of switch drawer room and cable vault, described switch drawer indoor are provided with multiple vertically disposed switch drawer, in the upper end of described cabinet lower end and cabinet side with ventilation hole, described ventilation hole is " S " type.
Its additional technical feature is:
Described ventilation hole center is provided with dowel;
Described ventilation hole vertical cross-section is interior narrow outer wide trapezoidal, and the vertical cross-section of described dowel is the trapezoidal of inner wide and outer narrow;
Described ventilation hole lateral cross section is interior narrow outer wide trapezoidal.
Low voltage drawing-out switching carbinet provided by the utility model compared with prior art, have the following advantages: one, owing to comprising the cabinet be made up of switch drawer room and cable vault, described switch drawer indoor are provided with multiple vertically disposed switch drawer, in the upper end of described cabinet lower end and cabinet side with ventilation hole, described ventilation hole is " S " type, work as paper scrap, the strip such as leaf or petiole foreign material by wind to ventilation hole time, because ventilation hole is " S " type, foreign material keep off outside cabinet by ventilation hole edge, avoid paper scrap, leaf or petiole strip foreign material enter in switch cabinet, its two, owing to being provided with dowel in described ventilation hole center, adding the impact strength of cabinet and avoid entering of foreign material further, they are three years old, because described ventilation hole vertical cross-section is interior narrow outer wide trapezoidal, the vertical cross-section of described dowel is the trapezoidal of inner wide and outer narrow, like this, when dust or rainwater etc. drop in the upper and lower both ends of the surface of ventilation hole, rainwater and dust can drop on outside ventilation hole under gravity, avoid dust and rainwater enters in cabinet, its four, because described ventilation hole lateral cross section is interior narrow outer wide trapezoidal, further avoid dust or foreign material enter in cabinet.

Fig. 2 is the structural representation of low voltage drawing-out switching carbinet side;
Fig. 3 is the enlarged drawing of ventilation hole;
Fig. 4 is the A of Fig. 3 ventilation hole---A profile;
Fig. 5 is the B of Fig. 3 ventilation hole---B profile.
Embodiment
Below in conjunction with accompanying drawing, the structure of the utility model low voltage drawing-out switching carbinet and use principle are described in further details.
As depicted in figs. 1 and 2, the utility model low voltage drawing-out switching carbinet, comprise the cabinet 3 be made up of switch drawer room 1 and cable vault 2, multiple vertically disposed switch drawer 4 is provided with in switch drawer room 1, in the upper end of cabinet 3 lower end and cabinet side with ventilation hole 5, ventilation hole is " S " type.When the strip foreign material such as paper scrap, leaf or petiole by wind to ventilation hole time, because ventilation hole is " S " type, ventilation hole edge by foreign material gear outside cabinet, avoid paper scrap, leaf or petiole strip foreign material and enter in switch cabinet.Make low voltage drawing-out switching carbinet can be applicable to various environment, and greatly extend in useful life.
As shown in Figure 2, ventilation hole 5 center is provided with dowel 6, adds the impact strength of cabinet and avoid entering of foreign material further.
If Fig. 3 and Fig. 4 ventilation hole 5 vertical cross-section is interior narrow outer wide trapezoidal, the vertical cross-section of dowel 6 is the trapezoidal of inner wide and outer narrow, like this, when dust or rainwater etc. drop in the upper and lower both ends of the surface of ventilation hole, rainwater and dust can drop on outside ventilation hole under gravity, avoid dust and rainwater enters in cabinet.
As shown in Figure 5, ventilation hole 5 lateral cross section is interior narrow outer wide trapezoidal, further avoid dust or foreign material enter in cabinet.
Protection range of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the structure of the utility model low voltage drawing-out switching carbinet, just drops on the scope of the utility model protection.
