Abstract
The utility model discloses a coil axial oil way structure which comprises an oil way rolled by insulation paper and is characterized in that the outer surface of the oil way is evenly provided with support strips along the axial direction. The support strips are used for supporting the oil way defined by the insulation paper, so that the strength of the oil way can be improved, the coil oil way is guaranteed to be smooth in circulation, and the heat dissipation effect of a coil is stabilized.
Description
Technical field
The utility model relates to a kind of coil axes to oil duct.
Background technology
At present, middle-size and small-size transformer cylindrical layer winding heat radiation is adopted the axial oil duct of corrugation, usually with insulating board cold-lap o ing; Because corrugated board intensity is limited, when coiling, receives the diametral force effect; The corrugation oil duct is easy to press and caves in, and supports failure, causes oil duct to stop up; The coil inside heat can't pass through the oil duct cycle heat radiation, makes the coil inside hot operation, thereby causes that transformer burns.
The utility model content
The purpose of the utility model provides the high coil axes of a kind of intensity to oil channel structure.
To achieve these goals, adopt following technical scheme: a kind of coil axes comprises the oil duct that is rolled into by insulating paper to oil channel structure, it is characterized in that: the outer surface of said oil duct in axial direction all is provided with support bar.
The utility model supports the oil duct that insulating paper surrounds through support bar, has increased the intensity of oil duct, has guaranteed that the circulation of coil oil duct is unimpeded, has stablized the radiating effect of coil.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the expanded view of Fig. 1;
Fig. 3 is the right view of Fig. 2.
Part 1 is water chestnut lattice insulating papers among the figure, and part 2 is a support bar.
Embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is further described.
To shown in Figure 3, a kind of coil axes comprises the oil duct that is rolled into by water chestnut lattice insulating paper 1 to oil channel structure like Fig. 1, and the outer surface of said oil duct in axial direction all is provided with support bar 2, and coil is wrapped on the support bar 2.Support bar 2 has strengthened the force intensity that receives of oil duct, has prevented that oil duct from caving in, and has guaranteed the safety of transformer.
