A kind of oil tank of transformer, comprise oil tank body and multiple corrugated plate, described oil tank body comprises four sidewalls, base plate and pony sills, the continuous U-shaped structure that four described sidewalls are formed in one also is arranged around described base plate, form the receiving space of a upper end open, described pony sill is located at below described base plate, and described corrugated plate cross section is zigzag, and sidewall described in four is evenly located at by multiple described corrugated plate.

In a kind of preferred embodiment of the oil tank of transformer provided at the utility model, described corrugated plate is hollow structure inside.

In a kind of preferred embodiment of the oil tank of transformer provided at the utility model, be provided with buffer spring between described base plate and described pony sill and reinforce corner block, described pony sill is for falling " ∏ " font, described buffer spring to be located between described " ∏ " word opening and to be connected described pony sill, and described reinforcing corner block is located at described pony sill and described back plate connections.

In a kind of preferred embodiment of the oil tank of transformer provided at the utility model, four described sidewalls and described plate inner wall are provided with insulating barrier.

In a kind of preferred embodiment of the oil tank of transformer provided at the utility model, be provided with reinforcement described in adjacent every two between sidewall, described reinforcement two ends connect sidewall described in two.

Compared to prior art, the described oil tank of transformer that the utility model provides has following beneficial effect:

One, there is not weld pads, oil-leakage-prevention in the continuous U-shaped structure that is formed in one of four described sidewalls, and production and processing is convenient, and be generally die casting and form, processing cost is low, and continuous U-shaped structure increases fuel tank external surface area, makes heat radiation more abundant.

Two, described corrugated plate is cross section is zigzag corrugated plate, and its inside is hollow structure, increases area of dissipation, and radiating effect is better, can alleviate the overall weight of described oil tank of transformer simultaneously.

Three, be provided with buffer spring between described base plate and described pony sill and reinforce corner block, described pony sill is for falling " ∏ " font, described buffer spring to be located between described " ∏ " word opening and to be connected described pony sill, described reinforcing corner block is located at described pony sill and described back plate connections, the fastness of described pony sill can be increased, extend the useful life of pony sill, described buffer spring also can prevent described bottom deformation simultaneously, reinforcement is provided with between sidewall described in adjacent every two, prevent described oil tank body distortion in the presence of a harsh environment, ensure that the fastness of installation, there are good market prospects.
