[0034] Oil level gauges are essential devices for monitoring transformer oil levels. However, in traditional designs, the orientation of the oil level gauge's window is often limited by the fixed orientation of the mounting flange (screws). Because different application scenarios require different angles and convenience for oil level observation, traditional oil level gauges often struggle to meet all requirements.

[0035] In view of the above problems, the present invention proposes a rotatable oil level gauge and transformer, the oil level gauge includes a tube body and a window, the window is provided on the tube body, and an annular rotating interface is provided at the connection between the tube body and the transformer oil tank, the annular rotating interface gives the tube body the ability to rotate freely around the interface, so that the user can easily adjust the direction of the window according to specific observation needs, thereby ensuring the intuitiveness and convenience of oil level monitoring. In addition, when installing a traditional oil level gauge, it is often necessary to adjust the flange welding direction due to the limitation of the window orientation, and the process is cumbersome and prone to errors. The rotatable oil level gauge of the present invention avoids this problem. The installer only needs to simply install the oil level gauge in place, and then adjust the window orientation by rotating the tube body, which greatly simplifies the installation process and improves work efficiency.

[0036] The present invention is specifically described through the following embodiments.

[0037] See also Figure 1 , Figure 1 The diagram shows the overall structure of the rotatable oil level gauge provided by the present invention. The oil level gauge comprises a tube body 110 and a viewing window 120. Window 120 is provided on tube body 110 for visual observation of the oil level. An annular rotating interface is provided at the connection between tube body 110 and transformer tank 130. This annular rotating interface rotatably connects to transformer tank 130, allowing tube body 110 to rotate relative to the tank, significantly enhancing the ease of operation of the oil level gauge.

[0038] In a possible embodiment, if Figure 1As shown, a seal 140 is provided at the annular rotating interface, thereby effectively preventing leakage of oil in the transformer oil tank 130 and ensuring stable operation of the oil level gauge.

[0039] In one feasible embodiment, a compression device is provided on the tube body 110. This device can directly act on the seal 140 to achieve a stable compression effect, thereby improving sealing performance. Specifically, the compression device consists of two parts: a compression structure and a pressure platform 210. The pressure platform 210 is positioned above the seal 140, and the compression structure is further firmly mounted on the pressure platform 210. It is worth noting that the area of ​​the pressure platform 210 can be designed to be larger than the area of ​​the seal 140 to ensure that the seal 140 is subjected to uniform and sufficient pressure, thereby further improving sealing performance.

[0040] See also Figure 2 , Figure 2 Schematic diagram of the structure of the pressing piece structure and the pressing platform provided by an embodiment of the present invention. The pressing piece structure includes a pressing block assembly 220 and a first fastener 230, wherein the pressing block assembly 220 is firmly pressed on the pressing platform 210 to form a tight fit. Figure 3 As shown, the pressing block assembly 220 is provided with a first screw hole 310, which allows the first fastener 230 to be accurately inserted and firmly locked, thereby ensuring a tight fixation between the pressing block assembly 220 and the pressing platform 210, further improving the sealing performance and structural stability. Figure 2 In the example, the pressure block assembly 220 is composed of four evenly distributed pressure blocks, each occupying an appropriate position on the surface of the pressure platform 210, and working together to ensure uniform and stable pressure distribution. However, it is worth noting that the composition of the pressure block assembly 220 is not fixed and can be adjusted according to actual needs. As long as it contains at least two pressure blocks, it can effectively achieve the purpose of compacting the pressure platform 210 and maintaining structural stability.

[0041] See also Figure 4 , Figure 4 This is a structural diagram of a pressing structure and a pressing platform provided by another embodiment of the present invention. The pressing structure can also be composed of a pressing ring assembly 410 and a second fastener 420. By introducing the pressing ring assembly 410 and the second fastener 420, the pressing ring assembly 410 is also firmly pressed on the pressing platform 210, forming a tight fit with the surface of the pressing platform 210. Figure 5 As shown, the pressure ring assembly 410 is provided with a second screw hole 530, which allows the second fastener 420 to be accurately inserted and firmly locked, thereby ensuring a tight fixation between the pressure ring assembly 410 and the pressure platform 210, further improving the sealing performance and structural stability.

[0042] Preferably, the first fastener 230 and the second fastener 420 are locking screws, thereby effectively ensuring a tight fit and firm compression between the pressing block assembly 220 and the pressing platform 210 , and between the pressing ring assembly 410 and the pressing platform 210 .

[0043] In a possible embodiment, if Figure 5 As shown, the pressure ring assembly 410 can be divided into a first annular pressure ring 510 and a second annular pressure ring 520, wherein at least one annular pressure ring is tightly integrated with the tube body 110 in structure to form a structural integral unit. That is to say, before welding the press plate 210, the pressure ring assembly 410 can be first installed on the tube body 110 to ensure the efficiency of subsequent assembly. Specifically, the first annular pressure ring 510 and the second annular pressure ring 520 are seamlessly connected to the tube body 110 during the manufacturing stage to form an inseparable whole. This installation method helps to ensure the positional stability of the tube body 110 and the pressure ring during the welding process, thereby improving the welding quality and sealing performance.

[0044] It should be noted that the pressure ring assembly 410 can not only be divided into a first annular pressure ring 510 and a second annular pressure ring 520, but can also be further refined into a larger number of annular pressure rings, such as three, four, or even more, according to actual needs. This modular design not only enriches the structural forms of the pressure ring assembly 410, but also provides wider applicability and stronger structural stability to meet the specific needs of different application scenarios.

[0045] In a feasible embodiment, the oil level gauge of the present invention covers multiple types such as a tube-type oil level gauge, a cup-type oil level gauge and a multi-function oil level gauge, and the user can select any one according to actual needs.

[0046] The present invention also provides a transformer that integrates the rotatable oil level gauge described in the previous embodiment with the transformer tank. The oil level gauge is mounted on one side of the transformer tank, and the user can easily adjust the orientation of the viewing window by rotating the gauge tube, enabling convenient observation of the oil level in the transformer tank.

[0047] The above is a specific description of the preferred implementation of the present invention, but the present invention is not limited to the above implementation.

These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
