Abstract
The utility model discloses a multi-window type transformer iron core fixture. The multi-window type transformer iron core fixture comprises a body and a wing plate, wherein the body is made of channel-section steel and bent to form an upward-open frame according to the outer contour of an iron core which is matched with the body, the two sides of a bottom plate are fixedly connected with the wing plate, and the middle portions of the upper portions of two vertical edges are respectively provided with a hosting hole, a main connecting hole and an auxiliary connecting hole. Two to five rows of windows with the hole interval ranging from 100mm to 180mm are arranged on board faces of the body so that the heat exchange area can be enlarged. By means of the windows, the weight of the fixture is reduced, most important of all, the contact area between oil in a transformer and the iron core of the transformer is effectively enlarged, the heat exchange effect is improved, the temperature of the iron core is effectively lowered, and the multi-window type transformer iron core fixture is beneficial for improving the running efficiency of the transformer.
Description
Technical field
The utility model relates to a kind of hardware, and specifically, the utility model relates to a kind of folder that is used for fastening transformer core.
Background technology
The iron core of most of transformers adopts stepped construction, by Structures of Multilayers Amorphous Alloys sheet or general silicon steel sheet, is stacked and is formed, and superimposed iron core adopts metal clip fastening conventionally, to keep Stability Analysis of Structures.The byproduct producing during transformer operation is heat, and the heat that wherein iron core produces is maximum.In order to reduce heat gathering in iron core, the technical measures of the industry are that iron core is immersed in transformer oil cooling.Technique measure is simple, easily capable, effective, can significantly reduce the heat of iron core.For example, but still there is the uneven problem of heat radiation, the position that iron core is clamped by folder in prior art, because folder has certain thickness, directly block the heat exchange of transformer oil and this place's iron core, cause local heat radiation not smooth, this problem has become one of reason of restriction transformer operational efficiency lifting.
Utility model content
The utility model is mainly for the deficiencies in the prior art, propose a kind of simple in structure, make easily, clamp reliable multi-window transformer core clamp.
The utility model is achieved through the following technical solutions technical goal.
Multi-window transformer core clamp, it comprises main body and wing plate.Described main body is bent into uncovered frame upward with channel-section steel by the outline of supporting iron core, and base plate both sides are fixedly connected with wing plate, and two vertical edge upper board faces are respectively equipped with lifting eye, main connecting hole and secondary connecting hole.Its improvements are: described main board face is provided with 2～5 rounds apart from the window of alternate 100mm～180mm.
Window ara in said structure is 2000mm
2～8000mm
2, window be shaped as oeil de boeuf, or be a kind of of rectangular window, triangular window, trapezoid window.
As further improvement project, on main board face, with above-mentioned difform window, combine.
The utility model compared with prior art, has following good effect:
1, uniform window on main board face, simple in structure, makes easily;
2, uniform window on main board face, the contact area of increase transformer oil and iron core, improves heat transfer effect, reduces iron core temperature;
3, uniform window on main board face, reduces accessory weight.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 schematic side view.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Multi-window transformer core clamp shown in the drawings, it comprises main body 1 and wing plate 2.Described main body 1 use channel-section steel is bent into uncovered frame upward by the outline of supporting iron core, and base plate both sides are fixedly connected with wing plate, and two vertical edge tops are respectively equipped with the main connecting hole 1.3 of lifting eye 1.4 and secondary connecting hole 1.1 between two parties.The supporting SBH15-2500/10(2500KVA of the present embodiment) iron core of transformer, main body 1 plate face width degree 366mm, long 1765mm, on main body 1 plate face width degree, establish 3 row's windows 1.2, the alternate 160mm of Width pitch-row, longitudinal hole is apart from alternate 120mm, window 1.2 is the oeil de boeuf of Φ 70, and its area is 3846.5mm
2, this structure does not reduce the intensity of main body 1.The utility model, by uniform window on main body 1 plate face, except reducing folder own wt, the most important thing is effectively to increase transformer oil and iron core contact area, improves heat transfer effect, effectively reduces iron core temperature, is conducive to improve the operational efficiency of transformer.
The utility model is located at window (1.2) quantity and the shape on main body (1) plate face, do not falling on low intensive basis, mainly by the specification of matching transformer, determine, the supporting folder size of large specification iron core is relatively large, its main body (1) plate face width degree is also corresponding wider, establish a few row's windows 1.2 more, otherwise establish less a few row's windows 1.2.Shape for window 1.2 is unimportant, can select arbitrarily a kind of, also can difform window 1.2 assembled arrangement, can reach the object that increases heat exchange efficiency effect.
Claims (6)
