Problems solved by technology
[0002] At present, most of the oil storage tanks used for oil-immersed inverted current transformers are processed by integral mold casting. Using this processing method, the product mold needs to be specially designed in the early stage, which has high mold development costs, long production cycle and later mold maintenance.

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] Such as figure 1 As shown, a manufacturing method of a 500 kV oil-immersed inverted current transformer oil conservator, the model is LVBT-500, comprising the following steps:
[0022] Step 1: Stretching and making two identical bowl-shaped shells 1 in the shape of a bowl;
[0023] Step 2: Fasten the open ends of the two bowl-shaped shells 1 seamlessly, and perform spot welding or full welding connection on the outside, and grooves should be made befor...

The invention provides a manufacturing method of a 500kV oil-immersed inverted current transformer oil conservator. The manufacturing method comprises the following steps of: step 1, stretching to manufacture two same bowl-shaped shells in a bowl shape; step 2, seamlessly buckling the open ends of the two bowl-shaped shells, and performing spot welding or full-length welding connection on the outer sides; step 3, cutting the cross section where the open ends of the vertical bowl-shaped shells are located to generate two U-shaped shells; step 4, performing repair welding on the welding parts onthe inner sides and the outer sides of the two U-shaped shells to be complete; step 5, respectively forming holes in the closed ends of the two U-shaped shells, and welding flanges; and step 6, respectively welding shell edge strips on the edges of the open ends of the two U-shaped shells to complete the manufacturing of an upper oil conservator and a lower oil conservator. According to the manufacturing method, a processing mode of stretching and welding aluminum parts is adopted, and the casting processing by adopting a mold is avoided, so that the cost for designing and developing the moldand the time for manufacturing the mold are saved, the production and processing efficiency can be greatly improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to a method for manufacturing a 500-kilovolt oil-immersed inverted current transformer oil storage tank, and belongs to the technical field of processing and manufacturing oil-immersed inverted current transformer oil storage tanks.
