Description
Technical field
The utility model is related to a kind of power control cabinet, especially a kind of insulated metal ring main unit.
Background technology
Metal enclosed ring main unit, in 24kV three-phase alternating current 50Hz electric system, as receiving and distribution electric energy and right
Circuit carries out control, protection and monitoring, generally by shell, on-load switch, current transformer, earthing switch, bus-bar room, instrument
Room, branch's busbar, connecting cable form, and high pressure inlet wire is connected by the main busbar in bus-bar room with on-load switch upper contact head, point
High-voltage terminal is connected by branch busbar with contact under on-load switch, and current transformer, sensor and ground connection are installed on main busbar
The on off state of switch, on-load switch and earthing switch can be manually controlled by the handle hole on operating mechanism.It is existing
The electric elements such as the main busbar of metal enclosed ring main unit, branch's busbar, on-load switch, breaker, current transformer, earthing switch
It is exposed in air, be easily affected by larger.Especially in use, setting in the adverse circumstances such as high humility, high pollution
Standby each component moisture-sensitive and corrosion, reduce the insulation performance and service life of product, and equipment maintenance cost is high.
Invention content
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of simple in structure, reduction is set
The insulated metal ring main unit that standby component makes moist and corrodes.
To achieve the above object, the utility model uses following technical scheme：
A kind of insulated metal ring main unit, including cabinet, the lower end of the cabinet are equipped with a pedestal, the cabinet and pedestal it
Between be equipped with ventilation hole, the side at the top of the cabinet is equipped with air outlet, and the cabinet is divulged information by ventilation hole and air outlet to be dissipated
Heat, the pedestal include the air inlet being arranged in four side of pedestal, and the air inlet is equipped with filter, the middle part of the pedestal
Equipped with wind turbine, wind turbine drives air to enter ventilation and heat in cabinet from ventilation hole, be equipped in the filter dust-filtering plate and
Drying plate, the dust-filtering plate include the filter cloth bag of sealing two ends and one be set to it is rectangular in the filter cloth bag
The sheet frame of shape, the filter cloth bag is taut to be sleeved on the sheet frame, and the drying plate is Reticular breathable structure, is equipped in drying plate dry
Drying prescription.
The air inlet and air outlet are shutter.
The drier is silica-gel desiccant.
The dust-filtering plate and drying plate are inwardly set gradually by air inlet.
The utility model uses above technical scheme, wind turbine driving air to enter ventilation and heat in cabinet from ventilation hole, into
Since there are air negative pressures, and extraneous air to be made endlessly to enter in cabinet at air port, the good heat dissipation effect of cabinet,
When the side of cabinet is equipped with air inlet and air outlet, and cabinet is placed, the air inlet or air outlet of side are blocked and do not influence out
Close the ventilation and heat of cabinet, extraneous air entered by air inlet after by filter, successively by dust-filtering plate and drying plate,
The dust and moisture gone out in air, make the equipment in switchgear be in a good working environment, avoid dust and
Moisture causes the insulation effect of switchgear to reduce.
Description of the drawings
The utility model is described in further details below in conjunction with the drawings and specific embodiments：

Specific implementation mode
As shown in one of attached drawing 1-3, the utility model includes cabinet 1, and the lower end of the cabinet 1 is equipped with a pedestal 2, described
Ventilation hole 3 is equipped between cabinet 1 and pedestal 2, the side at the top of the cabinet is equipped with air outlet 11, and the cabinet passes through ventilation
Hole 3 and 11 ventilation and heat of air outlet, the pedestal 2 include the air inlet 21 being arranged in four side of pedestal, on the air inlet 21
Equipped with filter 22, the middle part of the pedestal is equipped with wind turbine 23, and wind turbine 23 drives air to enter ventilation in cabinet 1 from ventilation hole 3
It radiates, dust-filtering plate and drying plate is equipped in the filter 22, the dust-filtering plate includes the mistake of a sealing two ends
Filter cloth bag and a rectangular sheet frame being set in the filter cloth bag, the filter cloth bag is taut to be sleeved on the sheet frame, institute
It is Reticular breathable structure to state drying plate, and drier is equipped in drying plate.The air inlet and air outlet are shutter.It is described dry
Drying prescription is silica-gel desiccant.The dust-filtering plate and drying plate are inwardly set gradually by air inlet.
The utility model wind turbine driving air enters ventilation and heat in cabinet from ventilation hole, and air inlet is since there are air
Negative pressure makes extraneous air endlessly enter in cabinet, and the good heat dissipation effect of cabinet is equipped in the side of cabinet
Air inlet and air outlet, the air inlet or air outlet of side are blocked the ventilation and heat for not influencing switchgear when cabinet is placed, outside
The air on boundary entered by air inlet after by filter, successively by dust-filtering plate and drying plate, the dust in air of going out
And moisture, so that the equipment in switchgear is in a good working environment, avoiding dust and moisture leads to switchgear
Insulation effect reduces.
