Embodiment Construction
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0025] Such as Figure 1 ~ Figure 7 As shown, the present invention provides a ring-shaped compensation type underwater transformer, which uses a ring-shaped bellows for pressure compensation, including a base 1, a shell 2, a transformer winding 3, a ring-shaped bellows compensator 4, and a connecting compartment 5. . The base 1 is provided with a casing 2, and the casing 2 is provided with a transfo...

The invention relates to an annular compensation type underwater transformer. The annular compensation type underwater transformer comprises a base, a shell, a transformer winding, a circular annularcorrugated pipe compensator and a connection cabin, wherein the shell is arranged on the base, the transformer winding is arranged in the shell, and the circular annular corrugated pipe compensator encircles the shell, is connected with the shell and also is arranged on the base. By the annular compensation type underwater transformer, the compensation rate of the compensator can be improved, meanwhile, the integral height of the transformer is prevented from being increased by the compensator, the longitudinal height size of the transformer is reduced, and the gravity center is reduced. And the annular compensation type underwater transformer can be applied in an underwater oil-gas production system.
Description
Technical field [0001] The invention relates to the field of underwater electrical equipment, in particular to an annular compensation type underwater transformer. Background technique [0002] The basic structure of an underwater transformer is to install the transformer in a sealed casing, and the insulating oil is filled between the transformer and the casing. Underwater transformers need to withstand sea water pressure and heat at the same time during deep sea work. Underwater transformers work on the bottom of the deep sea and bear the pressure of sea water. Transformer losses radiate outward in the form of heat, so underwater transformers are also subject to heat. While the transformer goes through different working conditions, the insulating oil will expand and contract with temperature. If seawater penetrates into the insulating oil in the shell of an underwater transformer, the transformer will fail. Therefore, except for special circumstances, the normal and reliabl...
