Embodiment Construction

[0030] The following examples are combined with the attached Figure 1-3 , the technical solutions of the present invention are further described in detail.

[0031] as attached figure 1 As shown, the present invention provides an underwater transformer, which includes a transformer main body 1, a casing, a base 2 and a compensator 3; the casing includes an outer casing 5 and an inner casing 6, and a top cover is provided on the top of the casing 4. The shell is combined with the base 2 and the top cover 4 to form the inner space 7 of the transformer and the middle space 8 of the transformer. The compensator 3 is set to the outer space 9 of the compensator and the inner space 10 of the compensator, and the inner space 10 of the compensator is connected to the transformer. The inner space 7 is connected and filled with transformer oil, the inner space 10 of the compensator performs pressure compensation on the inner space 7 of the transformer, the outer space 9 of the compensa...

Abstract

The underwater transformer includes the main body of the transformer, the shell, the base and the compensator. The top of the shell is provided with a top cover, and the shell is set to two layers: inner and outer layers. The compensator is set as an inner and outer two-layer bellows structure space. The inner space of the compensator communicates with the inner space of the transformer and is filled with transformer oil. The inner space of the compensator performs pressure compensation on the inner space of the transformer, and the outer space of the compensator It communicates with the middle space of the transformer and is filled with transformer oil, and the outer space of the compensator performs pressure compensation on the middle space of the transformer. The invention adopts the modular redundant design of double-layer shell, inner-guided double-layer bellows compensator and multiple compensators, and has the advantages of high reliability, good safety, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an underwater transformer. Background technique [0002] With the increasing demand for energy in the international community, the development of deep-sea oil and gas worldwide has become increasingly active. In addition to the construction of a large number of surface oil and gas production platforms in the process of deep-sea development, underwater production systems have also become an important part of deep-sea marine engineering technology. [0003] At present, the composite method of hydraulic fluid and electrical control, that is, composite electro-hydraulic control technology, is widely used in underwater production systems. The concept of all-electric control without relying on hydraulic fluid has great appeal in subsea production control systems. Underwater all-electric control technology can improve the reliability of the entire underwater system, and also has ...
