Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an amorphous alloy oil-immersed transformer. Background Art

[0002] At the end of the 19th century, transformers began to use transformer oil as an insulating and cooling medium, and oil-immersed transformers appeared. In addition to its abundant natural storage and low price, transformer oil has been widely used due to its following characteristics: During the use of oil-immersed amorphous alloy transformers, the air gaps between the components of the transformer can be filled with transformer oil, and the air can be discharged to prevent the components from being affected by moisture and causing a decrease in insulation strength.

[0003] And in the document with publication number CN213277731U, an amorphous alloy oil-immersed transformer is mentioned. The transformer is actually operated by starting the transformer body. During the operation, the transformer oil inside the oil level tube is sufficient. At this time, the sliding plate is pushed away from the oil level tube under the action of oil pressure. Then, by rotating the mounting plate on the mounting tube, the first battery and the second battery are placed above the first conductive plate and the second conductive plate respectively. After the placement is completed, the mounting plate is closed. Finally, with the use of the transformer body, the transformer oil inside the oil level tube is continuously consumed. When the oil level is lowered to a certain position, the transformer oil inside the operating tube no longer resists the side wall of the sliding plate inside the operating tube. The sliding plate slides on the fixed rod without the action of oil pressure, and is reset to slide toward the direction of the oil level tube by a spring. During the sliding of the sliding plate, The interaction between the inclined groove and the horizontal slide groove on the fixed plate and the transmission rod drives the transmission rod to slide upward on the sliding groove, and further pushes the first battery on the first conductive plate toward the second conductive plate and against it through the transmission plate, so that the circuits between the first battery, the second battery first conductive plate, the second conductive plate and the alarm are connected, the starting device is turned on, and the alarm starts to alarm. It has a simple structure and a high degree of automation, and can form an alarm device for low oil level on the transformer oil level tube. The operator can add transformer oil in time according to the prompt, which improves the protection of the transformer oil to the amorphous alloy transformer. However, there are still certain defects that need to be optimized. The specific defects are as follows: the oil level tube may accumulate impurities due to long-term use, which affects the observation of the oil level and the movement of the sliding plate. At the same time, there are too many parts in the operating tube, and it is difficult to repair.

[0004] Therefore, it is particularly important to design an amorphous alloy oil-immersed transformer to change the above technical defects and improve the overall practicality. Utility Model Content

As the oil in the oil level tube 201 and the operating tube 3 gradually decreases, the first compression spring 204, the second compression spring 301, the first telescopic rod 205, and the second telescopic rod 302 gradually extend. At this time, the pressure sensor does not receive the oil pressure. When the value is 0, the electric telescopic rod 408 is started.
