Abstract
The utility model discloses a kind of low capacity distribution transformer corrugated tank, there are the multiple corrugated plates being positioned at outside, the case on corrugated plate top is provided with angle steel along place, described angle steel by corrugated plate together with the Plate Welding of bottom, the both sides corrugated plate being positioned at case angle place has prolongation and dogleg section around the corner respectively, and described prolongation and dogleg section weld together.Compared with prior art, while ensureing transformer work safety, under its condition repeatedly changed at pressure can be made, possess swollen contracting function for a long time, effective guarantee is provided to power supply safety, and structure is simple, weight reduction, cost-saving.
Description
Technical field
The utility model belongs to electrical equipment technical field, and be specifically related to a kind of low capacity distribution transformer corrugated tank, structure is simple and cost-saving.
Background technology
For oil-immersed full-sealed distribution transformer; fuel tank adopts corrugated fin-type welding to be a kind of common structural shape; in the technical process that corrugated plate and upper tank are welded along angle steel and lower steel plate; under normal circumstances; an equal leg angle is respectively welded in fuel tank corner; upper tank forms a skeleton along angle steel and lower steel plate, conveniently welds corrugated plate; Simultaneously in order to strengthen the intensity of integral solder fuel tank, reduce the fuel tank Leakage caused due to the insufficient strength of corrugated plate itself.
Utility model content
The utility model provides a kind of structure simple low capacity distribution transformer corrugated tank, can ensure the reliability of Oiltank structure, can reduce again the weight of fuel tank, when can reduce Welder, cost-saving simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: this low capacity distribution transformer corrugated tank, there are the multiple corrugated plates being positioned at outside, it is characterized in that: the case on described corrugated plate top is provided with angle steel along place, described angle steel by corrugated plate together with the Plate Welding of bottom, the both sides corrugated plate being positioned at case angle place has prolongation and dogleg section around the corner respectively, and described prolongation and dogleg section weld together.
Described corrugated plate is that steel plate is made, and thickness is 1.0-2.0mm.
Described corrugated plate thickness is 1.5mm.
Adopt the beneficial effect of technique scheme: this low capacity distribution transformer corrugated tank makes its structure simple, cost-saving in guarantee corrugated tank firm foundations.For 500kKV and following corrugated tank, the intensity considering corrugated plate itself enough, in the process of welding fuel tank, removes the equal leg angle of fuel tank corner, the corrugated plate bending on both sides is extended and directly welds together.The equal leg angle of mailbox corner is replaced with the corrugated plate of welding.While ensureing transformer work safety, under its condition repeatedly changed at pressure can be made, possess swollen contracting function for a long time, effective guarantee is provided to power supply safety, and structure is simple, weight reduction, cost-saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Fig. 1 is that the fuel tank corner of prior art is with equal leg angle structural representation.
Fig. 2 is that novel fuel tank corner is without equal leg angle structural representation.
Fig. 3 is the fuel tank angle partial structurtes schematic diagram of Fig. 2.
Wherein: 1, corrugated plate 2, case are along angle steel 3, equal leg angle 4, prolongation 5, dogleg section.
Embodiment
Prior art as shown in Figure 1: fuel tank corrugated plate 1 by the case on top along angle steel 2 with the Plate Welding of bottom together with, middlely supported by the equal leg angle 3 of corner, both sides corrugated plate overlaps at equal leg angle place and welds together.
Embodiment of the present utility model is as shown in Figure 2: this low capacity distribution transformer corrugated tank, there are the multiple corrugated plates 1 being positioned at outside, the case on corrugated plate 1 top is provided with angle steel 2 along place, described angle steel 2 passes through corrugated plate 1 together with the Plate Welding of bottom, the both sides corrugated plate being positioned at case angle place has prolongation 4 and dogleg section 5 around the corner respectively, and described prolongation 4 and dogleg section 5 weld together.Described corrugated plate is hot rolling or cold-rolled steel sheet, and thickness is 1.0-2.0mm, preferably 1.5mm.The equal leg angle of mailbox corner is replaced with the corrugated plate of welding.While ensureing transformer work safety, under its condition repeatedly changed at pressure can be made, possess swollen contracting function for a long time, effective guarantee is provided to power supply safety, and structure is simple, weight reduction, cost-saving.
