Abstract
The utility model discloses a cabinet equipped with functions of heat radiation and electromagnetic shielding. Two large sides of a shell of the cabinet are provided with four heat radiation areas, a plurality of heat radiating holes are arranged in the heat radiation areas, the plurality of heat radiating holes are arranged in three rows in rectangular shapes. The horizontal distances between each two horizontally adjacent heat radiating holes are 5 mm, the vertical distances between each two vertically adjacent heat radiating holes are 6 mm, the heat radiating holes are round, and the diameter of each radiating hole is 7.234 mm. The cabinet equipped with the functions of heat radiation and electromagnetic shielding allows the cabinet to be equipped with the functions of heat radiation and electromagnetic shielding by the arrangement of heat radiating holes on the cabinet.
Description
Technical field
The utility model relates to a kind of cabinet be used to laying power equipment, relates in particular to a kind of cabinet that has heat radiation and electro-magnetic screen function concurrently.
Background technology
Along with " protection is transferred " pattern is also promoted by the electric power system approval gradually; make electromagnetic environment that the protective device that is positioned at switch yard faces than being positioned at harsh many of main control room, and for radio-frequency radiation wherein, disturb and do not cause enough understanding.In recent years,, along with the appearance of the on-line monitoring equipment based on communication, brought new radio-frequency electromagnetic interference problem.On the other hand, increasingly extensive to the application of integrated circuit type protective relaying device in electric power system that the radio frequency electromagnetic interference is comparatively responsive, this has just proposed new higher requirement to the ability of protective device resisting radiation interference.Electromagnetic shielding is the effective ways that the form of inhibition electric field causes interference, yet actual shield is because the functions such as heat radiation, ventilation and operation need, the upper general hole seam different, that size is different that all has in its surface, these hole seams have larger impact for the screening effectiveness of shield, can not accomplish to have concurrently at present the function of heat radiation and electromagnetic shielding at concerned power electric power cabinet used.
The utility model content
The purpose of this utility model provides a kind of cabinet that has heat radiation and electro-magnetic screen function concurrently with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of cabinet that has heat radiation and electro-magnetic screen function concurrently, be provided with four heat dissipation region on two large sides of the shell of described cabinet, be provided with a plurality of louvres in described heat dissipation region, the rectangular arrangement of a plurality of described louvres, described louvre is three rows, between described louvre between left and right every 5mm, between described louvre between the upper and lower every 6mm, described louvre is circular, and the diameter of described louvre is 7.234mm.
Particularly, interval 90mm between two heat dissipation region on the same large side of the shell of described cabinet.
The beneficial effects of the utility model are:
A kind of cabinet that has heat radiation and electro-magnetic screen function concurrently of the utility model, the arrangement mode by louvre on cabinet has accomplished to make cabinet to have heat radiation and electro-magnetic screen function concurrently.
Description of drawings
Fig. 1 is a kind of structural representation that has the cabinet of heat radiation and electro-magnetic screen function concurrently of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of cabinet that has heat radiation and electro-magnetic screen function concurrently of the utility model, be provided with four heat dissipation region on two large sides of the shell 1 of cabinet, be provided with a plurality of louvres 2 in heat dissipation region, the rectangular arrangement of a plurality of louvres 2, louvre is three rows, between louvre 2 between left and right every 5mm, between louvre 2, between the upper and lower every 6mm, louvre 2 is circular, and the diameter of louvre 2 is 7.234mm.
Interval 90mm between two heat dissipation region on the same large side of the shell 1 of cabinet.
Use the operation principle of a kind of cabinet that has heat radiation and electro-magnetic screen function concurrently of the utility model as follows:
The utility model is in the situation that keep identical with the draught area of traditional cabinet, adopt circular louvre 2 to replace the louvre of original various shapes, the diameter of louvre 2 is 7.234mm, the rectangular arrangement of a plurality of louvres 2, louvre is three rows, between louvre 2 between left and right every 5mm, between louvre 2 between the upper and lower every 6mm, in most frequency ranges, more than electromagnet shield effect improves 15dB.
Claims (2)
1. one kind has heat radiation and the cabinet of electro-magnetic screen function concurrently, it is characterized in that: be provided with four heat dissipation region on two large sides of the shell of described cabinet, be provided with a plurality of louvres in described heat dissipation region, the rectangular arrangement of a plurality of described louvres, described louvre is three rows, between described louvre between left and right every 5mm, between described louvre between the upper and lower every 6mm, described louvre is circular, and the diameter of described louvre is 7.234mm.
