Abstract
The present invention provides a kind of low-tension switch cabinet spacing board and low-voltage cabinet with ir-flow guide function, and the spacing board includes spacing board ontology, the heat emission hole with kuppe is densely covered on the spacing board ontology.The low-voltage cabinet includes spacing board and cabinet, and the heat emission hole with kuppe is densely covered on the spacing board ontology.The heat emission hole is circle, and the kuppe is horn-like.The spacing board is mounted on cabinet is divided into multiple compartments by the cabinet.The present invention can greatly improve air in cabinet and flow, and improve the heat dispersal situations in low-voltage complete switch equipment and control device cabinet；And in the case of arcing occurs, exploding gas slewing export cabinet, promotes low-voltage complete switch equipment and control device temperature rises and security performance.
Description
Technical field
The present invention relates to a kind of low voltage complete sets, and in particular to a kind of low-tension switch cabinet interval with ir-flow guide function
Plate and low-voltage cabinet.
Background technology
Electric power component is required for matching greatly, and electric power component is needed according to different using between function and security regulations
It is mounted in low-voltage complete cabinet different compartments every ground, however electric power component can generate amount of heat at runtime, heat is too late
When distribute and can cause electric power component temperature rise, hydraulic performance decline adversely affects the operation of equipment, and exists certain
Security risk, it is therefore desirable to improve the heat dissipation performance of low voltage complete set.Meanwhile when short trouble causes arcing, occur
The short time generates a large amount of high temperature and harmful exploded gas in the compartment of arcing, must orient exploded gas in the most fast time and export
Compartment and cabinet avoid exploded gas from assembling in compartment and cabinet, unordered to distribute, and destroy cabinet body structure so as to cause around cabinet
For the person and the second accident of property damage.
Heat emission hole usually is opened up on cabinet partition board to improve the heat dissipation performance of low-voltage equipment in the prior art, however it is such
The gas that scheme only relies on the size of temperature difference between different compartments and generates flows naturally so that and gas flow rates are relatively low, and
And airflow direction is more spuious, can not accomplish one-way flow or even reverse flow, so that the scheme for only opening up heat emission hole dissipates
The thermal efficiency is relatively low.Meanwhile when short trouble causes arcing, common heat emission hole can not only ensure that exploded gas is unidirectionally quickly arranged
Go out, and exploded gas crosstalk adjacent compartments can be caused, expand causality loss.
Invention content
It is a kind of with ir-flow guide function so as to provide it is an object of the invention to solve problems of the prior art
Low-tension switch cabinet spacing board and low-voltage cabinet.
It is a kind of with the low of ir-flow guide function as the first aspect of the present invention according to technical solution provided by the invention
Cabinet spacing board is pressed, the spacing board includes spacing board ontology, heat emission hole, the peritreme of heat emission hole are densely covered on the spacing board ontology
On be provided with kuppe.
Further, the heat emission hole is circle, and the kuppe is horn-like.
As the second aspect of the present invention, a kind of low-voltage cabinet with ir-flow guide function, the low-voltage cabinet includes spacing board
And cabinet, heat emission hole, heat emission hole connection kuppe are densely covered on the spacing board ontology.The heat emission hole is circle, described
Kuppe is horn-like.The spacing board is mounted on cabinet is divided into multiple compartments by the cabinet.
From the above as can be seen that low-tension switch cabinet spacing board and low pressure provided by the invention with ir-flow guide function
Cabinet has advantages below compared with prior art：First, the kuppe can play guiding role to air-flow, effectively control
Cabinet interior air-flow direction, when arcing failure occurs, most fast time interior orientation export exploding gas, ensures equipment safety to greatest extent.
Second, horn-like kuppe 2 can accelerate air flow rate, in-cabinet temperature can be fast and effeciently reduced.

Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in more detail.Wherein identical parts are presented with like reference characters.Need what is illustrated
It is that word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the direction in attached drawing.It uses
Word " interior " and " outer " refer respectively to towards or away from the direction of particular elements geometric center.
As depicted in figs. 1 and 2, as the first aspect of the present invention, a kind of low-voltage cabinet spacing board with ir-flow guide function,
The spacing board includes spacing board ontology 1, is densely covered with heat emission hole 110 on the spacing board ontology 1, in the peritreme of heat emission hole 110
Kuppe 2 is provided with, the kuppe 2 can play air-flow in guiding role, effective switch board interior air-flow direction, in arcing event
Most fast time interior orientation export exploding gas, ensures equipment safety to greatest extent when barrier occurs.
As shown in Fig. 2, the heat emission hole 110 is circle, the kuppe 2 is horn-like.Horn-like kuppe 2 can
Accelerate air flow rate, can fast and effeciently reduce in-cabinet temperature.
As shown in Fig. 1 ~ 3, as the second aspect of the present invention, a kind of low-voltage cabinet with ir-flow guide function, the low pressure
Cabinet includes spacing board and cabinet 3, and the spacing board is mounted on cabinet 3 is divided into multiple compartments 4 by the cabinet 3.Described
Partition board includes spacing board ontology 1, and heat emission hole 110 is densely covered on the spacing board ontology 1, and heat emission hole 110 connects kuppe 2, institute
Air-flow can be played guiding role, effective switch board interior air-flow direction, the most fast time when arcing failure occurs by stating kuppe 2
Interior orientation exports exploding gas, ensures equipment safety to greatest extent.The heat emission hole 110 is circle, and the kuppe 2 is loudspeaker
Shape.Horn-like kuppe 2 can accelerate air flow rate, can fast and effeciently reduce in-cabinet temperature.
The principle of the present invention is：It is guided by horn-like kuppe 2 and air-flow is accelerated to flow.
Those of ordinary skills in the art should understand that：The above is only a specific embodiment of the present invention, and
