Abstract
The invention discloses a power supply cabinet used for a high frequency switching power supply. The power supply cabinet used for the high frequency switching power supply comprises a power supply cabinet body, the power supply cabinet body is of an integrated sealing structure, cover plates are arranged on the relative position of a front panel and the relative position of a rear panel of the power supply cabinet body, a dust screen and a fan casing are arranged on each cover plate from outside to inside in sequence, and a fan is arranged in each cover plate. The power supply cabinet used for the high frequency switching power supply is of the integrated sealing structure, the dust screens are arranged on the cover plates to prevent dust from entering, the circuit ageing phenomenon caused by overweight of dust on circuits can be prevented effectively, and the service life is prolonged.
Description
Technical field
The present invention relates to power cabinet technical field, be specifically related to a kind of power cabinet for high frequency switch power.
Background technology
At present, high-frequency switch rectifying power supply has been widely used in the fields such as telecommunications, electric power, oil, once electric main breaks down, high-frequency switch rectifying power supply will lean on its standby battery group to maintain the power supply to DC load, the discharge time of batteries is limited, not president's time sustain discharge.
In the multiple occasions such as power plant, transformer station, UPS system, batteries is the visual plant that guarantees uninterrupted power supply and Emergency use, and when batteries is normally worked, its working temperature is to weigh the important parameter whether batteries normally works.Many conventional electronic and electrical equipments and components and parts very difficult long term maintenance under high ambient temperature is normally moved, at high temperature operation, and equipment itself needs to produce more heats, cause the interior temperature rise of rack very high, thereby acceleration equipment is aging and inefficacy.Therefore, for meeting device interior and components and parts, normally work, extend their useful life, the ambient temperature in rack need to be remained in the temperature range that equipment and components and parts can normally work; In addition, dust is also the reason that power source loads increases, reduces its useful life.
Summary of the invention
For above-mentioned prior art, the object of the present invention is to provide a kind of power cabinet for high frequency switch power, be intended to solve the problem that power cabinet internal cause temperature raises or the overweight acceleration equipment of dust is aging and lost efficacy.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of power cabinet for high frequency switch power, it is characterized in that, comprise power cabinet cabinet, described power cabinet cabinet integral body is hermetically-sealed construction, on the front panel of the power cabinet cabinet position relative with rear board, be provided with cover plate, on cover plate, be provided with successively from outside to inside Air Filter and fan guard, in cover plate, be provided with fan.
Described Air Filter is made by sponge or nonwoven fabrics.
Compared with prior art, the present invention has following beneficial effect:
The present invention's integral body is hermetically-sealed construction, and is on the cover board provided with Air Filter, stops dust to enter, and can effectively prevent that circuit because dust is overweight and the circuit aging phenomenon that causes, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Reference numeral is: 1 is that Air Filter, 2 is that fan guard, 3 is that display screen, 4 is cover plate.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
A kind of power cabinet for high frequency switch power, comprise power cabinet cabinet, described power cabinet cabinet integral body is hermetically-sealed construction, power cabinet cabinet top is divided into display screen, on the front panel of the power cabinet cabinet position relative with rear board, be provided with cover plate, on cover plate, be provided with successively from outside to inside Air Filter and fan guard, in cover plate, be provided with fan.Described Air Filter is made by sponge or nonwoven fabrics.
The present invention's integral body is hermetically-sealed construction, and is on the cover board provided with Air Filter, stops dust to enter, and can effectively prevent that circuit because dust is overweight and the circuit aging phenomenon that causes, increases the service life.
