Abstract
The utility model discloses a wind cooling high-voltage switch cabinet, which comprises a cabinet body, wherein an air inlet is formed on the front plate of the cabinet body, an air outlet is formed at the rear part of the cabinet body, and an exhaust fan is arranged at the air outlet in a communicating manner. The utility model is simple in structure and is convenient in use. The exhaust fan is arranged at the air out in a communicating manner, so that the phenomenon that a positive pressure gas circuit exists in the traditional cabinet can be eliminated, air inside the space of the cabinet can be exhausted from the air outlet smoothly, and the problem of heat-dissipation dead space existing inside the traditional cabinet can be solved. After a valve is removed, the wind resistance is reduced, and the energy consumption of a fan is reduced.
Description
Technical field
The utility model relates to a kind of air-cooled high-tension switch cabinet.
Background technology
Along with the development of economic society, China increases year by year to the demand of electric power in recent years, and society is also increasing to the demand of big electric current, big capacity power consumption equipment.For metal armouring draw out switchgear cabinet, the situation lower cabinet body that is no more than 2500A in the main bus bar rated current can be controlled temperature in the cabinet by natural heat dissipation system and natural heat dissipation structure.But after the main bus bar rated current surpassed 2500A, cabinet was difficult to control the temperature of cabinet in safe range by the natural heat dissipation structure.Chinese patent ZL200420113994.X discloses a kind of pull-out type high-tension switch cabinet forced air cooling device, is provided with the forced ventilation blower fan in switch cubicle, and is provided with the parts that valve, locking shell fragment etc. are used for separating the cabinet space in cabinet.Though this device can come to be the cabinet cooling that have following shortcoming: 1. structure is comparatively complicated by forced ventilation.2. the setting of valve, locking shell fragment etc. has also increased windage, thereby has increased energy consumption.3. blower fan outward blows to cabinet in by cabinet wind, make blast be dispersed in the cabinet inner space, be exported to by blower fan and can form malleation wind path smoothly between the cabinet air outlet, but this wind path pressure is higher, make the interior high-temperature gas of cabinet outside this wind path be difficult for discharging, therefore have the dead angle of dispelling the heat from air outlet.4. dust easily enters cabinet inside from air inlet, and easily heating was impaired after element covered dirt in the cabinet.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, energy consumption is lower and do not have the air-cooled high-tension switch cabinet at the dead angle of dispelling the heat.
For achieving the above object, air-cooled high-tension switch cabinet of the present utility model comprises cabinet, is provided with air inlet on the header board of cabinet, is provided with air outlet at the rear portion of cabinet, and the air outlet connection is provided with air exhauster.
Described air inlet is one group of parallel groove shape air inlet that is arranged side by side, and this group air inlet is covered with filter screen outward.
Be provided with temperature sensor and electric control gear in the described cabinet, temperature sensor is connected with the electric control gear signal, electric control gear and described air exhauster control connection.
The utlity model has following advantage:
1. the utility model is simple in structure, and is easy to use.Air outlet is communicated with and is provided with air exhauster, so just eliminated the phenomenon that has the positive pressure gas road in the cabinet in the past, the gas that is had living space in the cabinet all can be discharged from air outlet swimmingly, solve the problem that has the dead angle of dispelling the heat in the cabinet in the past.Also reduce windage behind the cancellation valve, reduced the energy consumption of blower fan.
2. air inlet is covered with filter screen outward, makes that dust is difficult for entering in the cabinet, thereby element is not subjected to effect of dust in the protection cabinet.
3. the setting of temperature sensor and electric control gear, can be in cabinet temperature when surpassing set point, automatically start by electric control gear control air exhauster, thereby blower fan only starts when temperature is higher, can either guarantee that the cabinet temperature is not too high, blower fan can when not reaching set point, the cabinet temperature do not started again, the energy loss that fan operation brings when avoiding the cabinet temperature low.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the right view that removes Fig. 1 behind the filter screen.
Embodiment
As shown in Figure 1, air-cooled high-tension switch cabinet of the present utility model comprises cabinet 1, is provided with air inlet 2 on the header board of cabinet 1, is provided with air outlet 3 at the rear portion of cabinet 1, and air outlet 3 connections are provided with air exhauster 4.Described air inlet 2 is one group of parallel groove shape air inlet that is arranged side by side, and this group air inlet is covered with filter screen 5 outward.Be provided with temperature sensor 6 and electric control gear 7 in the described cabinet 1, temperature sensor 6 is connected with electric control gear 7 signals, electric control gear 7 and described air exhauster 4 control connections.
When in the cabinet in 1 temperature rise, when meeting or exceeding the temperature value of setting, electric control gear 7 control air exhausters 4 start, form negative pressure in cabinet 1, the cabinet outer air will enter cabinet 1 by air inlet 2 like this, and the high-temperature gas in the cabinet 1 is then discharged by air outlet 3 and air exhauster 4.When in-cabinet temperature drops to the temperature value of setting when following, electric control gear 7 control blower fans 4 are out of service with the energy that avoids waste.
Claims (3)
