Description

Technical Field

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

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). Transformers are currently more important equipment in power construction and have been widely installed in various parts of my country. Oil-immersed transformers use mineral oil as the main insulating medium and cooling medium of the transformer. The main components of the transformer are immersed in an oil tank filled with mineral oil, and the wiring terminals are led out from the top of the oil tank cover. Compared with other types of transformers, oil-immersed transformers have a relatively simple structure, relatively low cost, and low maintenance cost. Therefore, they are widely used and are an indispensable electrical equipment in the current power supply network system. The body of the oil-immersed transformer is installed in an oil tank filled with transformer oil, and the oil tank is welded with steel plates.

[0003] However, during the existing assembly of the transformer oil tank, due to its relatively heavy weight, it needs to be moved and transported by hoisting. During the transportation process, its wiring terminals are directly exposed to the outside world and cannot be protected. During transportation or hoisting, it is easy to collide with other objects and cause damage, affecting subsequent use. In addition, it cannot provide good protection during daily use, which will accelerate the aging of the oil tank body and affect its service life. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides an embodiment: an oil-immersed transformer oil tank, including an oil tank body 1 of the oil-immersed transformer, which is equipped with transformer components and mineral oil to ensure cooling and insulation during use, and wiring terminals are led out at the top of the oil tank body 1 for easy connection and use. It is a relatively mature technology and will not be described in detail here. Heat dissipation fins 20 are arranged on the sides of the oil tank body 1 to assist in heat dissipation during use. In order to provide protection for the wiring terminals during transportation and hoisting, and to protect against sunlight and rain during use, columns 5 are vertically welded at the four corners of the top of the oil tank body 1, and a protective cover 6 is installed on it through a limiting mechanism.

[0023] See also Figure 1-Figure 5In order to adjust the height of the protective cover 6 according to the needs of use, it can be closed when protecting and opened when in use to protect from the sun and rain, and the degree of opening can be conveniently adjusted. The top of the side wall of the column 5 is equidistantly provided with a sliding cavity 17 of the reset component in the limit mechanism, and a moving plate 16 is slidably connected thereto through a spring 18, and a limiting piece 15 is welded at one end of the moving plate 16 away from the spring 18, and the moving plate 16 slides out of the sliding cavity 17 and extends to the outside, and limiting holes 9 adapted to be plugged in with the limiting piece 15 are equidistantly provided on the side surface of the protective cover 6, so that the height of the protective cover 6 can be adjusted according to the actual situation, thereby facilitating operations such as mobile transportation and subsequent connection and use, and in order not to affect the subsequent use, the protective cover 6 can also be removed, or it can be in an open mode, and its surrounding side is The rotating rod 13 of the rotating opening component is connected to the rotating baffle 7. In order not to affect the rotation while ensuring the sealing, a rubber pad 8 is bonded to the top of the rotating baffle 7. In order to limit and fix it to prevent the rotating baffle 7 from rotating, the top of the protective cover 6 is equidistantly provided with fixing holes 12 of the fixing component, in which a fixing column 11 is inserted, and a pull plate 10 for convenient pushing and pulling is welded on the top. The rotating rod 13 is equidistantly provided with plug-in holes 14 that are plugged in and compatible with the fixing column 11. The number of the plug-in holes 14 can be two groups, that is, plug-in and fix when closed, and plug-in and fix when the rotating baffle 7 is opened and rotated 90°. It can also be three or four groups, etc., which can be plug-in and fixed when rotated 45° or 60° to control the opening angle and ensure the sun protection effect. The opening is set according to the actual situation.

[0024] See also Figure 1-Figure 5 In order to facilitate the lifting of the fuel tank body 1 and the subsequent assembly operations, two groups of mounting plates 2 are equidistantly welded at its bottom, and mounting holes 19 are opened on it, which can be threaded holes, that is, they can be engaged and fixed by bolts, and the bottom of the mounting plate 2 is bonded with an anti-slip pad 4 to ensure stability during placement and avoid sliding, which is convenient for subsequent installation and positioning. At the same time, in order to facilitate the lifting operation and ensure the stability of the lifting, both ends of the mounting plate 2 are welded with lifting rings 3, and the side wall of the fuel tank body 1 is also welded with a lifting ring 3. When lifting, it can be fixedly connected to the lifting ring 3 on the mounting plate 2 by a lifting rope, and then pass through the lifting ring 3 on the fuel tank body 1, and then be lifted after winding, which can ensure stability during the lifting process.

[0025] Working principle: When the utility model is in use, when the oil tank body 1 is hoisted, the rotating baffle 7 on the protective cover 6 is in a closed state. At the same time, the protective cover 6 can provide protection for the wiring terminals on the top of the oil tank body 1, which is convenient for subsequent hoisting, transportation, assembly and other operations, and prevents the wiring terminals from colliding with other objects and the like during this process and causing damage. The lifting rope of the hoisting equipment is fixedly connected to the lifting ring 3 on the mounting plate 2, and then passes through the lifting ring 3 on the oil tank body 1. After winding, it is hoisted again, which can ensure stability during the hoisting process, and then it can be hoisted and transported. During subsequent installation, it can be installed and fixed through the mounting hole 19 on the mounting plate 2. At this time, the protective cover 6 can be removed according to actual conditions, or it can be moved up to open the rotating baffle 7 for protection. By pressing the limit piece 15, the movable plate 16 can be slid in the sliding cavity 17, and the spring 18 The protective cover 6 is thus removed or lifted up, and after the lifting is completed, the movable plate 16 and the limiting member 15 are reset and enter the limiting hole 9 under the action of the potential energy of the spring 18, so that the protective cover 6 can be positioned and fixed. When the rotating baffle 7 needs to be opened, the fixing column 11 is taken out from the fixing hole 12 and the insertion hole 14 by pulling the pull plate 10. At this time, the limiting position of the rotating rod 13 is lost, and the rotating baffle 7 can be rotated to open. After opening to a suitable angle, the fixing column 11 can be inserted into the fixing hole 12 and the insertion hole 14 of the rotating rod 13 at the same time, so that it can be limited and fixed, thereby preventing the adjusted rotating baffle 7 from rotating. After opening, it can play a role of sun protection and rain protection in subsequent use, and can provide certain protection for the fuel tank body 1, thereby improving the service life and safety.
