Description
Technical field
This utility model belongs to technical field of electric equipment, relates to a kind of switch cubicle, specifically a kind of switch cubicle short-circuit preventing device.
Background technology
Switch cubicle is a kind of large electric equipment, it is widely used in different places, such as places such as skyscraper, residential quarters, industrial and mining establishment, construction sites, uses bad environments, dust is more, and containing substantial amounts of metal dust in the dust of some areas, it is attached on each electrical equipment in metal dust access switch cabinet, easily causes electrical equipment short circuit, cause the accidents such as fire, switch cubicle is short for service life, and fault rate is high, and potential safety hazard is many.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, the switch cubicle short-circuit preventing device of dedusting heat radiation.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of switch cubicle short-circuit preventing device, including casing, is provided with suction nozzle, is connected with casing bottom described suction nozzle in described casing, described suction nozzle top connects has air exhauster, described suction nozzle week side to be evenly distributed with air entry；
It is provided with electric magnet in described suction nozzle, is connected fixing, described electric magnet with casing by bolt bottom described electric magnet and connects power supply；
Several passages are all had on described casing both sides sidewall.
Further, it is provided with drainage screen in described passage.
The beneficial effects of the utility model: this utility model arranges suction nozzle in the middle part of switchgear cabinet, suction nozzle one end connects air exhauster, suction nozzle week side have air entry, passage is had at wall box, form switch cubicle outer air through passage to casing, then through air entry to suction nozzle, return to the peripheral passage outside switch cubicle finally by air exhauster, play cooling effect, by air-flow, the metal dust in casing is sucked in suction nozzle simultaneously；Installing electric magnet in suction nozzle, absorb into the metal dust in suction nozzle, the metal dust in effective clear switch cabinet, prevent metal dust to be attached in switch cubicle and cause short circuit on electrical equipment, protection switch cubicle is properly functioning；Drainage screen is set in passage, filters and enter the bulky grain dust contained in air in casing, it is ensured that cleaning in switch cubicle, extend switch cubicle service life.
Accompanying drawing explanation
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of switch cubicle short-circuit preventing device, casing 1 including switch cubicle, being provided with the suction nozzle 2 running through casing 1 in the middle part of casing 1, be connected with bottom casing 1 bottom suction nozzle 2, suction nozzle 2 top connects through casing 1 top cover air exhauster 3,2 weeks sides of suction nozzle are evenly distributed with air entry 4, air in casing 1 enters suction nozzle 2 through air entry 4, extracts out outside switch cubicle by air exhauster 3, plays thermolysis.
Electric magnet 5 it is provided with in suction nozzle 2; fixed with being connected bottom casing 1 by bolt 7 bottom electric magnet 5; electric magnet 5 connects power supply 6, and power supply 6 is arranged in casing 1, and electric magnet 5 energising has magnetic; constantly bled by air exhauster 3; metal dust in casing 1 is drawn in suction nozzle 2 under the drive of air-flow, absorption metal dust on electric magnet 5, in effective clear switch cabinet; preventing metal dust to be attached in switch cubicle and cause short circuit on electrical equipment, protection switch cubicle is properly functioning.
It is positioned on the sidewall of casing 1 both sides and all has three passages 8, connection outside air, when air exhauster 3 is bled, outside air enters in casing 1 by passage 8, form circulating current, in passage 8, be provided with drainage screen 9, enter, for filtering, the bulky grain dust contained in air in casing 1, ensure cleaning in switch cubicle, extend switch cubicle service life.
Utility model works principle: when air exhauster 3 runs, air in suction nozzle 2 is drawn out of outside switch cubicle, suction nozzle 2 internal gas pressure declines, and the air in casing 1 enters suction nozzle 2 by air entry 4, brings in suction nozzle 2 by the metal dust in casing 1 simultaneously, it is attached on electric magnet 5, realizing removing metal dust work, now casing 1 internal gas pressure declines, and switch cubicle outer air enters in casing 1 by passage 8, form current path, play cooling effect.
This utility model arranges suction nozzle in the middle part of switchgear cabinet, suction nozzle one end connects air exhauster, suction nozzle week side have air entry, passage is had at wall box, form switch cubicle outer air through passage to casing, then through air entry to suction nozzle, return to the peripheral passage outside switch cubicle finally by air exhauster, play cooling effect, by air-flow, the metal dust in casing is sucked in suction nozzle simultaneously；Installing electric magnet in suction nozzle, absorb into the metal dust in suction nozzle, the metal dust in effective clear switch cabinet, prevent metal dust to be attached in switch cubicle and cause short circuit on electrical equipment, protection switch cubicle is properly functioning；Drainage screen is set in passage, filters and enter the bulky grain dust contained in air in casing, it is ensured that cleaning in switch cubicle, extend switch cubicle service life.
Above content is only to this utility model structure example and explanation; described specific embodiment is made various amendment or supplements or use similar mode to substitute by affiliated those skilled in the art; without departing from the structure of utility model or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
