Abstract
The utility model belongs to switchgear technical field, and in particular to a kind of low voltage drawing-out switching carbinet.The utility model pressure sensor monitors the pressure in cabinet in real time, when breaking down in cabinet, air pressure rise in cabinet, top relief valve and side relief valve are difference single stage by stage or open at the same time according to the pressure value in cabinet, the pressure and discharge gas in cabinet are fast and effeciently discharged on the premise of energy consumption is reduced, it is ensured that the safety of surrounding operations staff and switchgear；The utility model draw-out type low-voltage switch cabinet structure is simple, manufacture cost is low and has a safety feature, and is used easy to be widely popularized.
Description
Technical field
The utility model belongs to switchgear technical field, and in particular to a kind of low voltage drawing-out switching carbinet.
Background technology
Low voltage drawing-out switching carbinet is a kind of in the transmission of electricity of low-voltage, process of distributing electricity, and folding, control etc. are carried out to circuit
The equipment of operation, is widely used in the low-voltage distributions such as power plant, electric substation, petrochemical industry department, industrial enterprise, skyscraper
Electric energy conversion, distribution and the control of power, distribution and the Motor Control Center of system, capacitance compensation etc. are used；But in the prior art,
Low voltage drawing-out switching carbinet is there are the shortcomings that complicated, manufacture and maintenance cost are high, expensive, when wherein a low pressure is taken out
When going out formula switchgear generation short trouble, moment produces high temperature and high pressure gas, since cabinet does not have pressure-relief measure, causes adjacent
Switchgear is similarly subjected to damage.
Utility model content
In view of the deficienciess of the prior art, the utility model provides, one kind is simple in structure, manufacture cost is low and security
Good low voltage drawing-out switching carbinet.
The utility model is achieved through the following technical solutions：
A kind of low voltage drawing-out switching carbinet, including cabinet, the cabinet include the first cabinet above and following second
Cabinet, the first cabinet surface are provided with display window, are provided with master switch below the display window, in first cabinet
Controller is installed, several drawers are provided with second cabinet, the cabinet further includes pressure release passage, and the pressure release is led to
Road is located at the peripheral between the inner wall of the cabinet of first cabinet and the second cabinet, and the top of the cabinet is provided with top
Hold relief valve.
Further, pressure sensor is installed in the pressure release passage.
Further, the both ends outer wall of the cabinet is symmetrically arranged with side relief valve, the controller and pressure sensing
Device, top relief valve and side relief valve are electrically connected.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model pressure sensor monitors the pressure in cabinet in real time, when breaking down in cabinet, in cabinet
Air pressure rise, top relief valve and side relief valve are difference single stage by stage or open at the same time according to the pressure value in cabinet,
The pressure and discharge gas in cabinet are fast and effeciently discharged on the premise of energy consumption is reduced, it is ensured that surrounding operations staff and switch
The safety of equipment；
2nd, the utility model draw-out type low-voltage switch cabinet structure is simple, manufacture cost is low and has a safety feature, easy to extensive
Promote the use of.

In attached drawing：1. cabinet；2. first layer cabinet；3. second layer cabinet；4. display window；5. master switch；6. drawer；7. let out
Pressure passageway；8. pressure sensor；9. top relief valve；10. side relief valve；11. processor.
Embodiment
A kind of low voltage drawing-out switching carbinet as shown in Figure 1, including cabinet 1, cabinet 1 include 2 He of the first cabinet above
The second following cabinet 3,1 surface of the first cabinet are provided with display window 4, and the lower section of display window 4 is provided with master switch 5, the first cabinet
Controller 11 is installed in body 1, several drawers 6 are provided with the second cabinet 3, cabinet further includes pressure release passage 7, pressure release passage
7 between the first cabinet 2 and the periphery of the second cabinet 3 and the inner wall of cabinet 1, and the top of cabinet 1 is provided with top relief valve
9。
Further, pressure sensor 8 is installed in pressure release passage 7.
Further, the both ends outer wall of cabinet 1 is symmetrically arranged with side relief valve 10, controller 11 and pressure sensor 8,
Top relief valve 9 and side relief valve 10 are electrically connected.
Specific workflow is：Controller, which is set, according to the different demands of client opens top relief valve and side relief valve
Critical value, after master switch starts, pressure sensor monitors the pressure in cabinet in real time, when pressure rises to set first
During critical value, top relief valve is opened, and when pressure rises to the second set critical value, side relief valve is opened at the same time,
Pressure and discharge gas are effectively discharged with this stage by stage, it is ensured that the safety of surrounding operations staff and switchgear.
In conclusion the only preferred embodiment of the utility model, is not used for limiting the utility model implementation
Scope, the equivalent change carried out by all shapes according to described in the utility model claims scope, construction, feature and spirit is with repairing
Decorations, should all be included in the right of the utility model.
