Description

Technical Field

[0001] This utility model belongs to the field of oil tank maintenance technology, and particularly relates to a transformer oil tank maintenance device. Background Technology

[0002] Transformers are core components of power systems, mainly used for voltage control during long-distance power transmission. A transformer oil tank is installed on the outside of the transformer, and the inside of the oil tank is filled with insulating oil. The insulating oil helps to dissipate heat and seal the inside, thus protecting the internal components of the transformer.

[0003] Transformer oil tanks require maintenance periodically. Maintenance primarily involves checking the tank's sealing and the tightness of external connections. According to the maintenance cycle, the internal insulating oil needs to be cleaned. The conventional cleaning method uses filtration to filter the insulating oil. However, this type of filtration device lacks a modular design, resulting in a large overall size. It includes multiple components such as coarse filtration, fine filtration, oil-water separation, and heating, making the maintenance device bulky and inconvenient to move to the transformer's maintenance location. Heavier maintenance devices also require large forklifts for transport. Furthermore, the integrated structure makes it difficult to modularize the oil filter device, preventing the selection of appropriate modules for maintenance based on the specific needs.

[0004] In view of this, we propose a transformer tank maintenance device. Utility Model Content

When oil-gas separation is needed, fixing frame one, fixing frame two, and fixing frame three are all installed. Through modular design, it is convenient to select different modules for splicing and use as needed.

[0017] In this technical solution, the second oil filter can perform fine filtration of insulating oil to meet the application scenarios that require fine filtration.

[0018] In the above technical solution, the interior of the oil-gas separator mainly consists of a vacuum tank and a vacuum pump, which are connected to each other. The oil-gas separator is detachably connected to the oil filter.

[0019] In this technical solution, an oil-gas separator can be used to separate oil and water, ensuring the insulating effect of the oil.

[0020] In the above technical solution, furthermore, multiple sets of universal wheels are installed on the lower surfaces of the first, second and third fixing frames, and a reinforcing plate is fixedly installed on the lower surface of the first fixing frame.

When only coarse filtration is needed, the module on fixing frame 1 is used. When coarse filtration and fine filtration are needed, fixing frame 1 and fixing frame 2 are spliced ​​together. When oil-gas separation is needed, fixing frame 1, fixing frame 2, and fixing frame 3 are all installed. Through modular design, it is convenient to select different modules for splicing and use as needed.

[0037] The main module is located outside the fixed frame 1 and performs coarse filtration. The insulating oil inside the oil tank is pumped into the oil filter 4 by the oil pump 3 for coarse filtration. When the fixed frame 1 and the fixed frame 2 8 are paired, the fixed frame 2 8 is fixed by the connecting plate 7. At this time, the insulating oil undergoes coarse filtration, heating and fine filtration. When the fixed frame 1, the fixed frame 2 8 and the fixed frame 3 9 are combined, the insulating oil can undergo coarse and fine filtration and oil-gas separation. Different modules need to be selected and combined according to the processing requirements. The connecting plugs of multiple sets of equipment are electrically connected to the inside of the control box 5.

[0040] The oil extraction pipe is connected to the inside of a set of oil filters 4 using a quick-connect coupling. When the oil pump 3 starts, the insulating oil will enter the inside of the oil filter 4, and the insulating oil can be coarsely filtered by the internal metal filter screen.

[0041] Example 3: This example provides a transformer tank maintenance device. In addition to the technical solutions of the above examples, it also has the following technical features: the interior of the finned heater 6 is connected to the oil pump 3 through a pipe, and a heating component 15 is installed on one side of the finned heater 6.

In addition to the technical solutions of the above examples, it also has the following technical features: the other side of the finned heater 6 is connected to an output pipe 16, and the port of the output pipe 16 is connected to a booster pump 17.

[0045] Among them, the booster pump 17 can assist the flow of insulating oil, making the insulating oil treatment more efficient;

[0046] The booster pump 17 is started by the control box 5. Together with the oil pump 3, it can assist the flow of insulating oil and facilitate the output of insulating oil, which is suitable for the rapid treatment of insulating oil in small transformers.

[0048] Among them, oil filter 211 can perform fine filtration of insulating oil to meet the application scenarios that require fine filtration;

[0049] When fine filtration is required, the second fixing frame 8 is installed outside the first fixing frame 1 via the connecting plate 7. The port of the fine filter is connected to the port of the booster pump 17. At this time, the insulating oil output by the booster pump 17 can enter the interior of the fine filter. The fine filter and the silica gel adsorption tank work together to treat the fine particles in the insulating oil. Multiple sets of glass fiber filter elements are installed inside the fine filter. Multiple sets of fine filter fixing cylinders are connected in series to perform fine filtration on the insulating oil.

[0052] Connect the mounting brackets 1, 8, and 9. Connect the vacuum tank to the inside of the oil filter 11 through the interface. The oil can enter the vacuum tank and, after being atomized by the sprayer, fully contact the hydrophilic material inside the tank, thus preventing water vapor backflow. The vacuum breaking valve will periodically replenish air to break the water vapor saturation state and improve the removal efficiency, ultimately efficiently removing water and gas from the oil.

In addition to the technical solutions of the above examples, it also has the following technical features: multiple sets of casters 18 are installed on the lower surfaces of the fixing frame 1, fixing frame 2, and fixing frame 3.

[0054] Among them, the casters 18 facilitate the movement of each module, and the bottom reinforcing plate 19 provides auxiliary support;

[0055] Each module can be moved by multiple sets of casters 18, making it easy to move individual modules. The upper surface of the reinforcing plate 19 is in contact with the lower surface of the second fixing frame 8, which can provide auxiliary support and improve the support effect.

[0056] Working principle: Different modules are selected and combined according to the filtration needs. For example, when only coarse filtration is needed, only the fixed frame 1 is used. When fine filtration is needed, the fixed frame 1 and the fixed frame 2 8 are connected by the connecting plate 7 and the fixing bolt 13. When oil-gas separation is needed, the fixed frame 1, the fixed frame 2 8 and the fixed frame 2 8 are connected.
