Abstract
The utility model discloses a stepped assembly structure for finned radiator groups; the stepped assembly structure comprises a transformer tank and a radiator, wherein a slant upper oil gathering pipe and a slant lower oil gathering pipe are respectively arranged at the upper side and the low side of the transformer tank; multi-group finned radiators are suspended at both sides of the upper oil gathering pipe and the lower oil gathering pipe; the upper oil gathering pipe and the lower oil gathering pipe are communicated with the radiator; the upper oil gathering pipe slants downward and forms a slant angle 'alpha' with the horizontal plane; and the lower oil gathering pipe slants upward and forms another slant angle 'alpha' with the horizontal plane. The stepped assembly structure has a simple structure and is convenient to manufacture and install.
Description
Technical field
The utility model belongs to field transformer, is specially a kind of gilled radiator group stairstepping assembly structure.
Background technology
The radiating effect of transformer depends on gilled radiator to a great extent; And whether rationally, efficiently the assembly structure of the radiating effect of gilled radiator and gilled radiator group has confidential relation.
Conventional gilled radiator assembling distribution structure is seen Fig. 3 (3 is that oil inlet pipe, 4 is that oil return pipe, 2 is radiator among the figure), the gilled radiator group is installed on the transformer body, the deep fat of transformer dispels the heat from body enters the fin of every group of radiator by oil inlet pipe, cold oil after the heat radiation flow back into the transformer body from oil return pipe, the circulation cooling.The main deficiency of this gilled radiator assembling distribution structure is that the oil inlet pipe of gilled radiator and oil return pipe are the contour structure of strip, it is inhomogeneous that oil resistance characteristic makes that deep fat enters the oil mass of each fin, fin oil-feed near the transformer body is many, fin oil-feed away from the transformer body is few, when the sheet number was a lot, the most inboard fin and the outermost fin temperature difference were very big; And being unfavorable for cold oil, gets back to fast in the transformer body the contour return duct of strip, prolong the oily circulation cooling cycle, reduced the radiating effect of radiator, increased the use of radiator material, increase the transformer manufacturing cost, this defective is more obvious in high-power transformer.
Summary of the invention
The purpose of this utility model: design a kind of gilled radiator group stairstepping assembly structure, make the radiator shunting evenly, improve radiating effect, save radiator material, reduce the transformer manufacturing cost.
The technical solution adopted in the utility model is: a kind of gilled radiator group stairstepping assembly structure, comprise oil tank of transformer and radiator, be respectively arranged with the top oil collecting pipe and the bottom oil collecting pipe of inclination in the both sides up and down of oil tank of transformer, many group gilled radiators are suspended on top oil collecting pipe and oil collecting pipe both sides, bottom, described top oil collecting pipe communicates with bottom oil collecting pipe and radiator, the top oil collecting pipe is downward-sloping to be inclination angle " α " with level, and the bottom oil collecting pipe is inclined upwardly and level is the inclination angle also for " α ".
Each organize gilled radiator height " H " from the most close oil tank of transformer position to reducing gradually away from the fuel tank position.
The top oil collecting pipe is downward-sloping, and to be inclination angle " α " be 5 ° or 10 ° with level, and the bottom oil collecting pipe is inclined upwardly and to be inclination angle " α " identical with oil collecting pipe inclination angle, top for level.
The deep fat of oil-immersed power transformer is positioned at the top of fuel tank, and cold oil is in the bottom of fuel tank, and behind utilization the utility model, deep fat is because the effect of gravity, shunts in the fin that enters radiator quickly along the inclination angle " α " of top oil collecting pipe and dispels the heat; Again because big near the gilled radiator area of dissipation of oil tank of transformer, gilled radiator area of dissipation away from oil tank of transformer is little, oil resistance characteristic makes near the radiator group oil-feed of transformer body many, radiator group oil-feed away from the transformer body is few, it is oil inlet quantity and area of dissipation coupling, so the oil that enters after the inside and outside radiator group cooling has a narrow range of temperature, the heat radiation balance is reasonable, and each radiator group is fully utilized; Cold oil after the cooling is because the effect of gravity, is back to the transformer body quickly along the inclination angle " α " of bottom oil collecting pipe, and oil heat radiation circulation is faster, and radiating effect is remarkable, has saved the gilled radiator material, has reduced the transformer manufacturing cost.
The utility model is simple in structure, manufacturing, easy for installation.

Specific embodiments
As depicted in figs. 1 and 2, a kind of gilled radiator group stairstepping assembly structure, comprise oil tank of transformer 1 and radiator 2, be respectively arranged with the top oil collecting pipe 4 and the bottom oil collecting pipe 3 of inclination in the both sides up and down of oil tank of transformer 1, many group gilled radiators 2 are suspended on top oil collecting pipe 4 and bottom oil collecting pipe 3 both sides, described top oil collecting pipe 4 communicates with bottom oil collecting pipe 3 and radiator 2, top oil collecting pipe 4 is downward-sloping to be inclination angle " α " with level, and bottom oil collecting pipe 3 is inclined upwardly and is the inclination angle with level and also is " α ".
Each organize gilled radiator height " H " from the most close oil tank of transformer 1 position to reducing gradually away from the fuel tank position.
As shown in Figure 3, the top oil collecting pipe is downward-sloping, and to be inclination angle " α " be 5 ° or 10 ° with level, and bottom oil collecting pipe 3 is inclined upwardly and to be inclination angle " α " identical with oil collecting pipe inclination angle, top for level.α=arctg described in the utility model (Δ H/L).
The utility model in use, for the oil tank of transformer that adopts trapezoidal roof construction, top oil collecting pipe 4 also can be drawn layout from the fuel tank case lid.
