Problems solved by technology

With the large-scale construction of UHV in China, large-scale power transformers are used in large quantities. How to reduce the loss of transformers and how to improve efficiency is in front of domestic power experts. Although they have developed generations of energy-saving transformers, due to The most important raw materials that affect the loss of transformers --- the conductivity of ordinary copper wires (or aluminum wires), the magnetic permeability of silicon steel sheets, and the eddy current loss have not been significantly improved, so the loss per unit capacity of the transformer has been difficult to continue. reduce

Embodiment 1

[0020] like figure 1 As shown, this embodiment provides an amorphous alloy core superconducting energy-saving transformer, including an iron core 1, a primary winding 2, a secondary winding 3 and a glass fiber reinforced plastic container 4, the iron core 1 is located in the glass fiber reinforced plastic container 4, and the primary winding 2 passes through The lead wire is connected to the AC power supply, the secondary winding 3 is connected to the load through the lead wire, the glass fiber reinforced plastic container 4 is filled with liquid nitrogen 5, and the glass fiber reinforced plastic container 4 includes a vacuum insulation layer 9 and a shock absorbing foot 10 arranged at the lower end of the transformer.

[0021] Due to the increasing maturity of liquid nitrogen 5 refrigeration technology, the cost of refrigeration is also constantly decreasing. The nitrogen gas can be maintained at a liquefied state of -196 degrees Celsius through the liquid nitrogen 5 refrigera...

Embodiment 2

[0023] This embodiment is optimized on the basis of the above-mentioned embodiment 1.

[0024] In order to realize continuous circulation of liquid nitrogen 5 , it also includes a first pipeline 6 and a second pipeline 7 communicating with the inside of the glass fiber reinforced plastic container 4 , and a liquid nitrogen compressor 8 is arranged between the first pipeline 6 and the second pipeline 7 .

Embodiment 3

[0026] This embodiment is optimized on the basis of the above-mentioned embodiment 1.

[0027] Both the primary winding 2 and the secondary winding 3 are made of high-temperature AC superconducting composite materials.

[0028] The superconducting property of the current high-temperature superconducting wire or strip is that it can be in a superconducting state when the resistance of the conductor is zero under the cooling of liquid nitrogen at -196 degrees Celsius and through direct current, and the loss is extremely low, but in the transformer winding The alternating current is not the direct current, so the high temperature superconducting material has a higher alternating current loss. In this technical solution, since the primary winding 2 and the secondary winding 3 both use high temperature It is an ultra-fine wire composite multi-core superconducting wire or superconducting strip with extremely low AC loss, which further ensures the outstanding energy-saving effect of ...

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an amorphous alloy core superconducting energy-saving transformer. Background technique [0002] In the more than 100 years since the invention and application of transformers, power experts from all over the world have been working on reducing transformer losses. With the large-scale construction of UHV in China, large-scale power transformers are used in large quantities. How to reduce the loss of transformers and how to improve efficiency is in front of domestic power experts. Although they have developed generations of energy-saving transformers, due to The most important raw materials that affect the loss of transformers --- the conductivity of ordinary copper wires (or aluminum wires), the magnetic permeability of silicon steel sheets, and the eddy current loss have not been significantly improved, so the loss per unit capacity of the transformer has been difficult to ...
