A marine superconducting transformer

Abstract

The invention discloses a marine superconducting transformer. The marine superconducting transformer comprises an iron core, a coil assembly, a low temperature vessel, a refrigerating machine, two pipelines and two flow guiding devices, wherein the coil assembly is wound on the iron core and is arranged in the low temperature vessel; the refrigerating machine is communicated with the low temperature vessel by virtue of the two pipelines; the two flow guiding devices are arranged in the two pipelines respectively; the coil assembly comprises an inner superconducting coil, an outer superconducting coil, multiple pairs of arc-shaped sawtooth clamping blocks and multiple arc-shaped insulating plates; and each flow guiding device comprises a conical valve head, a rotating shaft, a shaft sleeve and a pressure spring. The marine superconducting transformer disclosed by the invention has the characteristics of less disturbance of fluid and strong heat dissipating capability.

Description

technical field [0001] The present invention relates to superconducting transformers. Background technique [0002] At present, superconducting transformers are widely used, and some special occasions need to improve their performance. For example, when applied to ships, it is necessary to further reduce noise, save energy and enhance heat dissipation, and there are the following problems: [0003] 1) In some superconducting transformers, the coil and iron core are placed in a low-temperature container filled with cooling oil to maintain a low-temperature environment. Therefore, it is necessary to be equipped with a refrigerator and corresponding pipelines to keep the cooling oil at a continuous low temperature. However, when the refrigerant fluid passes through the valve, it is prone to turbulence and noise. Moreover, there is no structure to allow liquid to be introduced and exported during rotation, so it is not suitable for special operations. [0004] 2) The winding...

AI Technical Summary

Problems solved by technology

However, when the refrigerant fluid passes through the valve, it is prone to turbulence and noise

Moreover, there is no structure that allows the liquid to be introduced and exported during rotation, so it is not suitable for special operations

[0004] 2) The winding is suspended during the winding process and needs to be filled with objects, which reduces the heat dissipation performance of the wire surface

At the same time, since there is no interlayer between the inner and outer coils, the oil passage cannot be formed, which further reduces the heat dissipation efficiency of the transformer during operation.
