Specific embodiment
Below in conjunction with the accompanying drawings and the embodiment of the utility model makees into one the low pressure drawer-type switch cabinet of the utility model
Step detailed description.
As shown in Figure 1, Figure 2 and Figure 3, the low pressure drawer-type switch cabinet including cabinet 1 and is located at multiple inside cabinet 1
Drawer 2.Observation panel 22 is offered inside the panel 21 of the drawer 2, the hinged transparent panel 23 in 22 inside of observation panel makes transparent panel 23
Seal observation panel 22.
Monitoring personnel can observe the working condition of 2 internal part of drawer by transparent panel 23, ensure that switchgear is located for a long time
In working condition, and it can influence the service life of switchgear to avoid drawer monitoring is opened and influence operating personnel's life peace
The defects of complete.
If monitoring personnel observes the working condition for not knowing internal part across transparent panel 23, can be transparent by opening
Plate 23 does not influence the unimpeded of drawer circuit in opening procedure, ensures switchgear normal operating conditions；Also, long-term
It, can be saturating by opening for the working condition that can clearly observe 2 internal part of drawer of transparent panel 23 during use
Isotropic disk is wiped, and ensures the clarity of transparent panel 23；Even, in use, transparent panel 23 can be individually replaced, it is convenient
Monitoring personnel clearly observes 2 internal part of drawer.
In order to which observer can be facilitated completely to observe 2 internal part of drawer, and can ensure outside cabinet 1
Light can to pass through transparent panel 23, ensure observation clarity.It is mutually to be fitted with 21 structure of panel by 22 structure design of observation panel
(Aspect Ratio is identical, and size is less than 21 size of panel of drawer 2) is answered, in strip.It is opened in order to facilitate staff transparent
Plate 23,23 one end of transparent panel is hinged and 21 outer surface of panel, other end outside are equipped with pulling handle 24.Staff is when through saturating
During observation 2 inner case of drawer that isotropic disk 23 can not clean, it can be opened saturating by pulling handle 24 that transparent panel 23 is pulled to rotate
Isotropic disk 23 observes 2 internal part of drawer, and transparent panel 23 can be wiped, and ensures observing effect.
In order to ensure the intensity of transparent panel 23, insulation effect, ensureing the service life of transparent panel 23 and pass through transparent panel
The safety of 23 protection observers.The material selection of transparent panel 23 is tempered glass material.
In order to ensure, to the ventilation effect inside drawer 2, to ensure 2 internally dry effect of drawer, and drawer 2 can be sent out
The pollution air generated when raw abnormal is taken out of, avoids influencing the trouble free service of 2 internal unit of drawer；It can also be discharged by detecting
Whether abnormal gas are contained in air, and whether detection drawer works normally, and is further ensured that the safety of equipment.In the face of drawer 2
Air admission hole 3 is opened up inside plate 21, the back plate 25 of drawer 2 offers gas vent 4, and gas vent 4 is internally provided with exhaust fan 41.Due to cabinet
1 front environment of body is preferable, and air is cleaner, can be passed through inside drawer 2, by dirts such as moisture, the dusts inside drawer 2 from row
Stomata 4 is taken out of, ensures the safety of 2 internal part of drawer.
As shown in Figure 4 and Figure 5, in order to be dried and purified treatment to being passed through the air inside drawer 2, in air admission hole 3
Inside is removably connected with drying device 31 and filter device 32, and air admission hole 3 is made to be sequentially passed through into the air inside drawer 2
Filter device 32 and drying device 31.Since the size of venthole 3 is smaller, for convenience in drying device 31 and filter device 32
The drier and filtrate in portion are replaced, and drying device 31 and filter device 32 are detachably connected on inside venthole 3.
When needing replacing drier or filtrate, drying device 31 and filter device 32 can be dismantled inside venthole 3, directly
It connects and replaces spare drying device 31 and filter device 32, by the drying inside the drying device 31 changed and filter device 32
Agent and filtrate are replaced.
Preferably, drying device 31 includes housing 311, and 311 outer wall of housing is fixed with 3 inside removable seal of air admission hole,
311 both ends of housing are reticular lamina 312, filler particles shape drier between two reticular laminas 312.Overall structure is simple, reduces
Cost is manufactured, is detachably connected by housing 311 and 3 inner wall of air admission hole, dismounting and company of the convenient and dry device 31 with venthole 3
It connects.
Preferably, filter device 32 includes：Annular wall 321, outer plexiform layer 322 and inner plexiform layer 323,322 edge of outer plexiform layer with
Annular wall 321 is fixedly connected, and inner plexiform layer 323 is embedded in inside annular wall 321, is stayed and was set between outer plexiform layer 322 and inner plexiform layer 323
Screening cavity 324.Outer plexiform layer handle 325 is fixedly connected in 322 outer wall of outer plexiform layer, outer plexiform layer is pulled by outer plexiform layer handle 25
322, annular wall 321 is pulled out into venthole 3, since inner plexiform layer 323 is embedded in inside annular wall 321, so annular wall 321 is by band
The slip of dynamic inner plexiform layer 323, facilitates the dismounting and connection of filter device 32.Preferably, it is fixedly connected in 323 outer wall of inner plexiform layer
Inner plexiform layer handle 326 facilitates under staff dismantled inner plexiform layer by inner plexiform layer handle 326 from annular wall 321, so as to beat
Filtrate cavity 324 is opened, the convenient filtrate to inside filtrate cavity 324 is replaced.
In order to the sundries of drawer (dust, suspended matter) is discharged with moving air, in the back plate 25 of entire drawer 2
Lower end opens up multiple gas vents 4 and (since sundries is heavier, opens up gas vent 4 in 25 lower end of back plate, and under entire back plate 25 side by side
End opens up gas vent, avoids leaving dead angle inside pumping, accumulates dust and suspended matter).Each 4 row of being internally provided with of gas vent
Gas fan 41, exhaust fan 41 extracts the air inside drawer 2 out, and 2 inside source of drawer is made to ensure in negative pressure state inside drawer 2
Equipment safety works.
It is convenient that air is further processed or detected for the air centralized processing discharged to drawer 2, in cabinet 1
Cabinet plate is equipped with gas-guide tube afterwards, and the exhaust end of gas vent 4 is turned in gas-guide tube, and the air that venthole 4 is discharged is led by gas-guide tube
Stream discharge, also into other detection devices, facilitates realization detection process.
It is discharged in order to facilitate the dust in 2 inner air of drawer and suspended matter close to ground location, ensures switchgear place
The health of environment, gas-guide tube is vertically arranged, and gas-guide tube lower end is conducting to 1 bottom of cabinet, so that dust and suspended matter fall
It is deposited on ground, avoids being again introduced into drawer 2, influence the safety of 2 internal part of drawer.
The above is only the preferred embodiment of the utility model, is not intended to limit the protection of the utility model
Scope.
