Abstract
The utility model discloses a transformer oil tank which comprises a tank body and a tank cover on the tank body, wherein an upper collecting pipe and a lower collecting pipe are arranged on the tank body; radiating fins are connected between the upper collecting pipe and the lower collecting pipe; the transformer oil tank is characterized in that the lower collecting pipe is horizontally arranged; the upper collecting pipe adopts a step-shaped structure extending upwards in the direction gradually away from tank body; and the tail end part of the upper collecting pipe is higher than the tank cover. According to the transformer oil tank provided by the utility model, as the step-shaped radiating fin structure is adopted, the radiating centers of the finned radiators are higher, the top parts of the finned radiators are higher than the top part of the oil tank cover, the radiating center of the transformer is remarkably higher, the ratio of the transformer heating center to the transformer radiating center is reduced, the oil surface temperature rise of the transformer is reduced, and the heat radiating efficiency of the transformer oil tank is increased.
Description
Technical field
The utility model relates to a kind of transformer accessory, particularly relates to a kind of oil tank of transformer.
Background technology
At present, common gilled radiator fuel tank, its gilled radiator are to be positioned at below the fuel tank top cover basically; The ratio at transformer heating center and transformer heat radiation center is higher; According to the design of transformer principle, this ratio is high more, and transformer pasta temperature rise correction value is high more; The temperature rise of transformer pasta is also just high more, and the radiating effect of corresponding transformer is not fine just.
The utility model content
The purpose of the utility model provides a kind of oil tank of transformer of good heat dissipation effect.
To achieve these goals; Adopt following technical scheme: a kind of oil tank of transformer comprises casing and is arranged at the case lid on the casing that casing is provided with collecting main and lower header; Be connected with fin between last collecting main and the lower header; It is characterized in that: said lower header is for being horizontally disposed with, and last collecting main is upwardly extending ladder configuration on gradually away from the direction of casing, and upward the height of the end portion of collecting main is higher than case lid.
The utility model adopts the heat radiating fin structure of notch cuttype to improve gilled radiator heat radiation centre-height; Its gilled radiator top is surpassed fuel tank case lid top; Obviously improve transformer heat radiation center; Reduce the ratio at transformer heating center and transformer heat radiation center, reduced the temperature rise of transformer pasta, increased the radiating efficiency of oil tank of transformer.
Description of drawings
Fig. 1 is that the structure of the utility model is looked sketch map;
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure, part 1 is a casing, and part 2 is a case lid, and part 3 is a fin, and part 4 is last collecting main, and part 5 is a lower header.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2; A kind of oil tank of transformer comprises casing 1 and is arranged at the case lid 2 on the casing that casing is provided with collecting main 4 and lower header 5; Be connected with fin 3 between last collecting main 4 and the lower header 5; Wherein said lower header 5 is for being horizontally disposed with, and last collecting main 4 is upwardly extending ladder configuration on gradually away from the direction of casing, and upward the height of the end portion of collecting main is higher than case lid 2.Adopt the gilled radiator fuel tank of abnormity in the present embodiment, the heat radiation center of having improved gilled radiator makes the temperature rise of transformer pasta reduce, and has strengthened the radiating effect of fuel tank.
