Abstract
The utility model discloses a kind of box-type substation bi-layer tip cap structure, structure simple in structure, heat-sinking capability is strong, it is the box-type substation bi-layer tip cap structure for including big head cover and small head cover, through hole is provided with the middle part of the big head cover, the small head cover is fixed on above the through hole and leaves air duct between big head cover；The air duct is easy to the air circulation inside and outside box-type substation, ensure certain heat dissipation performance, in addition, since air duct is located at the top of box-type substation, the larger temperature difference is formed in substation in the height direction, so as to produce air pressure difference, stronger convection current is formed, increases the heat-sinking capability of box-type substation.
Description
Technical field
Field of electrical equipment is the utility model is related to, particularly a kind of top cover of box type transformer substation structure.
Background technology
Box-type substation is that a kind of prefabrication is indoor, outdoor close-coupled controller switching equipment, i.e., drops high powered, transformer
The functions such as pressure, low-voltage distribution are organically combined, installed in one moisture-proof, antirust, dust-proof, protection against rodents, fire prevention, it is antitheft, every
In hot, totally-enclosed, moveable steel-structure box body, electromechanical integration, a kind of brand-new substation of totally-enclosed operation.Transformer
It is indispensable device in box-type substation, and main heating device, but the working life of transformer is significantly
It is influenced by temperature, long term high temperature can shorten the service life of transformer, and box type transformation is also needed on the basis of radiating in transformer
Station possesses more preferable ventilation and heat condition；In addition, existing box for box-type transformer substation heat dissipation mainly passes through outer container tank wall ventilation hole
Radiate with head cover, but existing cap structure heat radiation energy force difference, cause box-type substation internal component easily to be damaged due to overheat
It is bad.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in correlation technique at least to a certain extent.For this reason,
The utility model proposes a kind of simple in structure, and the box-type substation bi-layer tip cap structure that heat-sinking capability is strong.
Technical solution is used by the utility model solves its technical problem：
A kind of box-type substation bi-layer tip cap structure, including big head cover and small head cover, the middle part of the big head cover, which is equipped with, to be led to
Hole, is provided with ventilation web plate in the through hole, and the small head cover is fixed on the top of big head cover and covers the ventilation web plate,
Air duct is left between the small head cover and big head cover, lower section is provided with aperture web plate in small tip cap edge, to prevent foreign matter
Enter from air duct in box-type substation.
As the improvement of above-mentioned technical proposal, the big head cover into terrace edge shape and forms inclined-plane by cover plate splice, described
Big head cover inclined design is trickled easy to rainwater so as to prevent ponding, and each cover board junction is provided with keel and strengthens connection.
Further as above-mentioned technical proposal is improved, and the small head cover is connected on the keel, by spine support simultaneously
Installation is fixed
Further, the cover board has multilayer, including thermal baffle layer, waterproof layer and the supporting plate layer for being used to support thermal insulation board.
Preferably, it is provided with weather shield on the outside of the aperture web plate.
Further, it is configured with suspension hook at the top of the small head cover.
The beneficial effects of the utility model are：The utility model structure simple in structure, heat-sinking capability is strong, it is to include top greatly
The box-type substation bi-layer tip cap structure of lid and small head cover, big head cover middle part are provided with through hole, and the small head cover is fixed
Air duct is left above the through hole and between big head cover；The air duct is easy to the air inside and outside box-type substation
Circulation, ensures certain heat dissipation performance, further, since air duct is located at the top of box-type substation, in height side in substation
The larger temperature difference is upwardly formed, so as to produce air pressure difference, stronger convection current is formed, increases the heat-sinking capability of box-type substation.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model partial sectional view；
Fig. 2 is I partial enlarged views；
Fig. 3 is the utility model top view.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of box-type substation bi-layer tip cap structure of the utility model, including big head cover 1 and little Ding
Lid 2, the middle part of the big head cover 1 are equipped with through hole, and ventilation web plate is provided with the through hole, and the small head cover 2 is fixed on big top
The top of lid 1 and the ventilation web plate is covered, air duct is left between the small head cover 2 and big head cover 1, in small head cover 2
Aperture web plate 3 is provided with below edge, to prevent foreign matter from entering from air duct in box-type substation.The air duct is easy to
Air circulation inside and outside box-type substation, ensures certain heat dissipation performance, further, since air duct is located at box-type substation top
Portion, forms the larger temperature difference in substation in the height direction, so as to produce air pressure difference, forms stronger convection current, increases case
The heat-sinking capability of formula substation.
In the present embodiment, the big head cover 1 into terrace edge shape and forms inclined-plane by cover plate splice, and the big head cover 1 is oblique
Face design is trickled easy to rainwater so as to prevent ponding, and each cover board junction is provided with keel 4 and strengthens connection；The small head cover
2 are connected on the keel 4, are supported by keel 4 and install fixation.The cover board has multilayer, including thermal baffle layer 11, waterproof
Layer 13 and the supporting plate layer 12 for being used to support thermal insulation board, the thermal baffle layer 11 prevent external environment condition heat transfer from causing temperature liter at head cover
Height, and make the height temperature difference in babinet be not enough to form larger convection current.
In addition, in the present embodiment, the outside of aperture web plate 3 is provided with weather shield 5, and rain is prevented while ventilative heat dissipation is ensured
Water is entered in box-type substation.Further, install and lift by crane for convenience of head cover, suspension hook 6 is configured with the small top of head cover 2.
