Abstract
The utility model discloses an oil tank for an oil-immersed transformer, comprising an upper cylinder body and a lower cylinder body that are whole cast and semicircle. A porcelain vase flange and an outlet flange are welded on the oil tank which is circle. The utility model has the advantages that the flange can be welded on the oil tank directly and auxiliary part welding is not needed, so cost is reduced and oil leakage does not occur easily after being used for long time; at the same time volume of the oil tank is less and structure is more reasonable.
Description
Technical field
The utility model relates to a kind of fuel tank, particularly a kind of oil immersed type instrument transformer fuel tank.
Background technology
Oil immersed type instrument transformer fuel tank in the market is the fuel tank of tetragonal body, all is welded to connect between the cylinder wall, after service time is long, and easy seepage oil; In addition, this top tank is designed to circle, when welded flange, can directly be welded on the top tank, need not to add in addition the auxiliary member welding, reduces cost; At last, this structure makes smaller volume, the more reasonable structure of fuel tank.
Summary of the invention
The utility model is to provide a kind of anti-leakage of oil, oil immersed type instrument transformer fuel tank that volume is little.
In order to solve above technical problem, the utility model comprises upper cylinder body and lower cylinder body, and described upper and lower cylinder body is the semi-circular cylinder body of cast-in-block, and the end face of described semicircle cylinder body is a square.
Be welded with porcelain vase flange and outlet seat flange on the described top tank.
The oil immersed type instrument transformer fuel tank of above structure, its advantage is: fuel tank is monoblock cast, nothing is oozed, oil leakage phenomenon; In addition,, more meet the use of instrument transformer because cylinder body is designed to circle, and reduced volume, light and flexible.
Description of drawings
Fig. 1 is the structural representation of the utility model upper cylinder body;
Fig. 2 is the structural representation of the utility model lower cylinder body.
Embodiment
As shown in Figure 1 and Figure 2, the bottom of upper cylinder body 1 and lower cylinder body 2 is round, and upper cylinder body end face 3 and lower cylinder body end face 4 are square; As shown in Figure 2, be welded with in the bottom of described lower cylinder body 2 that feet 5 is used to support and the balance of stable fuel tank, be equipped with column 6 on each angle of lower fuel tank end face 4 inboards, the purposes of column 6 is to fix when top tank 1 and lower fuel tank 2 are altogether.
As shown in Figure 1, the shape of top tank 1 is identical with the shape of lower fuel tank 2, but the welding of the bottom of top tank 1 be outlet flange 7 and porcelain vase flange 8, be used for being connected with instrument transformer; Certainly, as required, can also weld two or more flanges in the bottom of top tank 1, angle can be regulated arbitrarily.
Claims (2)
1. an oil immersed type instrument transformer fuel tank comprises upper cylinder body and lower cylinder body, it is characterized in that: described upper and lower cylinder body is the semi-circular cylinder body of cast-in-block, and the end face of described semicircle cylinder body is a square.
2. oil immersed type instrument transformer fuel tank according to claim 1 is characterized in that: be welded with porcelain vase flange and outlet seat flange on the described top tank.
