Embodiment Construction
[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Specific embodiments of the transformer of the present invention, such as Figure 1 to Figure 6 As shown, the transformer includes a transformer body (not shown in the figure) and an oil tank inside the transformer body. The transformer body refers to the main part of the transformer except the oil tank, which is the same as the prior art and will not be repeated here. The transformer in the present invention refers to an oil-immersed transformer with an oil tank. If other transformers with an oil tank are not called oil-immersed transformers, they still fall within the scope of the present invention.
[0021] The fuel tank includes a tank body 1 and a tank cover 2. The tank body 1 and the tank cover 2 are conventional or unconventional shapes in the prior art. The tank body 1 is mainly in the form of a cuboid or other hard shell, and its upper pa...

The invention relates to an oil-immersed transformer oil tank and a transformer employing the same. The transformer comprises a body and the oil tank, wherein the oil tank comprises a box body and a box cover, connection structures are arranged on the box cover and the box body and are connected with each other, each connection structure comprises a box body insertion hole or a box body insertion groove and a box cover insertion hole or a box cover insertion groove, the box body insertion hole or the box body insertion groove is formed in the box body, the box cover insertion hole or the box cover insertion groove is formed in the box cover, each connection structure also comprises a locking post, the locking post can be simultaneously inserted into the box body insertion hole or the insertion groove or the box cover insertion hole or insertion groove when the box cover is covered on the box body, and axial directions of the insertion holes or the insertion grooves are parallel to or incline with a horizontal plane. With the adoption of the transformer, the connection structures of the box body and the box cover are the insertion holes or the insertion grooves, the box body and the box cover are relatively locked by simultaneously inserting the locking post to the two insertion holes or the two insertion grooves, the transformer is simple in structure and is convenient to operate, and the problems of many bolts, complicated processing of threaded holes, complicated assembly and disassembly operation, relatively high fabrication and maintenance cost, high requirement on installation accuracy and the like existing in traditional bolt connection are solved.
Description
technical field [0001] The invention relates to a transformer oil tank, in particular to an oil-immersed transformer oil tank and a transformer using the oil tank. Background technique [0002] At present, the tank cover and the box body of the existing oil-immersed transformer oil tank adopt the following assembly method: the tank cover is generally fastened with bolts, so as to ensure that the tank cover and the box edge on the box body are tightly sealed to prevent the oil tank cover from seeping oil or Air leak. The Chinese patent with the authorized notification number CN2396487Y discloses a three-dimensional fully sealed transformer oil tank, which includes a box body and a box cover. The compression effect of the fastening bolts when tightening realizes the sealing of the box body. This bolt fastening structure has the following problems: First, the connection and fixation of the tank cover and the tank edge requires a lot of bolts to fix, and the process is cumbers...
