Abstract
A box cover with a super-high radiating function of a mining explosion-proof dry-type transformer relates to a transformer, and comprises a cover plate, a large flange, end plates, a small flange and graphite radiating fins. The edge of the cover plate is fixed onto the large flange, the cover plate is in butt joint with a box body through the large flange, the end plates are fixed to two sides above the cover plate, the small flange is arranged on the cover plate, and the graphite radiating fins wrap the surface of the cover plate. As the cover plate is a corrugated plate, the cover plate is thinned, raw materials are saved, the strength of the cover plate is enhanced and the superficial area of the cover plate is enlarged. The cover plate with a dome-shaped section has better compression strength so as not to be easy to deform. Besides, the radiating effect is greatly improved by the aid of a layer of graphite radiating fins wrapping the surface of the cover plate.
Description
Technical field:
The utility model relates to a kind of transformer, is specifically related to a kind of flameproof dry type transformer case lid with superpower heat sinking function.
Background technology:
Dry-type transformer is to rely on cross-ventilation to cool off, and the iron core of transformer and winding are immersed in the insulating oil, generally are divided into open type, closed and three kinds of forms of cast-type.The dry-type transformer of above-mentioned enclosed construction is usually used in having the place of requirement of explosion proof, if any the place of inflammable gas, dust.Existing flameproof dry type transformer corrugated casing mainly is made up of casing and case lid, connects through flange between casing and the case lid or is welded as a whole, and relative flange face utilizes bolted to be sealed and matched, and forms explosion-proof.Casing selects for use the corrugated steel plate to make, and case lid is to adopt plain plate to make, and the intensity of case lid is low, and in order to reach requirement of explosion proof, plain plate is generally chosen thicker steel plate, the waste raw material, and radiating effect is poor.
The utility model content:
The purpose of the utility model provides the flameproof dry type transformer case lid with superpower heat sinking function; It has saved raw material, has increased the intensity of cover plate, has increased the surface area of cover plate; At corrugated plating surface attachment one deck graphite radiating sheet, its radiating effect is greatly improved simultaneously.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises cover plate 1, big flange 2, end plate 3, little flange 4, graphite radiating sheet 5; The edge of cover plate 1 is fixed on the big flange 2, and cover plate 1 docks with casing through big flange 2, and end plate 3 is fixed on the both sides, top of cover plate 1, and little flange 4 is arranged on the cover plate 1, and graphite radiating sheet 5 wraps the surface that is attached to cover plate 1.
Described cover plate 1 is a corrugated plating, has reduced the thickness of cover plate 1, has saved raw material, has increased the intensity of cover plate 1, has increased the surface area of cover plate 1, attaches one deck graphite radiating sheet at the lid surface bag simultaneously, and its radiating effect is greatly improved.
The cross section of described cover plate 1 is a dome-shaped.Make cover plate 1 have compression strength preferably, not yielding.
Described end plate 3 is fixed on the both sides, top of cover plate 1, and end plate 3 capable of using lifts, and is convenient to install.
Passage when described little flange 4 can be used as inspection hole or maintenance transformer.
The utlity model has following beneficial effect: saved raw material, increased the intensity of cover plate, increased the surface area of cover plate, adhered to one deck graphite radiating sheet in lid surface simultaneously, its radiating effect is greatly improved.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the mounting structure sketch map of the utility model.
Embodiment:
Referring to Fig. 1-3, this embodiment adopts following technical scheme: it comprises cover plate 1, big flange 2, end plate 3, little flange 4, graphite radiating sheet 5; The edge of cover plate 1 is fixed on the big flange 2, and cover plate 1 docks with casing through big flange 2, and end plate 3 is fixed on the both sides, top of cover plate 1, and little flange 4 is arranged on the cover plate 1, and graphite radiating sheet 5 wraps the surface that is attached to cover plate 1.
Described cover plate 1 is a corrugated plating, has reduced the thickness of cover plate 1, has saved raw material, has increased the intensity of cover plate 1, has increased the surface area of cover plate 1, attaches one deck graphite radiating sheet at the lid surface bag simultaneously, and its radiating effect is greatly improved.
The cross section of described cover plate 1 is a dome-shaped.Make cover plate 1 have compression strength preferably, not yielding.
Described end plate 3 is fixed on the both sides, top of cover plate 1, and end plate 3 capable of using lifts, and is convenient to install.
Passage when described little flange 4 can be used as inspection hole or maintenance transformer.
This embodiment has been saved raw material, has increased the intensity of cover plate, has increased the surface area of cover plate, adheres to one deck graphite radiating sheet in lid surface simultaneously, and its radiating effect is greatly improved.
