Description

Technical Field

[0001] This utility model relates to the technical field of electric furnace transformers, and in particular to an oil tank for preventing leakage in electric furnace transformers. Background Technology

[0002] Electric arc furnace transformers are core equipment in the metallurgical industry, specifically designed for high-temperature smelting scenarios such as electric arc furnaces and submerged arc furnaces. Traditional power transformers cannot withstand the drastic current fluctuations, frequent short circuits, and high-temperature environments encountered during electric arc furnace operation. Electric arc furnace transformers, through special designs such as reinforced winding structure, increased short-circuit impedance, and optimized cooling systems (e.g., oil-immersed / water-cooled), ensure stable power supply under extreme conditions such as electrode arc ignition and furnace charge melting. Electric arc furnace transformers have many components, among which the oil tank is one of the most important.

[0003] The following problems exist with the oil tanks of electric furnace transformers currently on the market:

[0004] Before using existing electric furnace transformers, workers first add an appropriate amount of oil to the oil tank, which mainly serves the functions of insulation and cooling. The oil has a high boiling point, but the oil may seep into the tank cover and welded gaps due to excessive pressure inside the tank. Once seepage occurs, it may cause local overheating or discharge of the transformer, and in severe cases, it may cause hazards such as short circuits and explosions. Utility Model Content

However, the oil has a high boiling point, and the oil may seep through the tank cover and welded gaps due to excessive pressure inside the tank. Once seepage occurs, it may cause local overheating or discharge of the transformer, and in severe cases, it may cause short circuits and explosions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof oil tank for an electric furnace transformer, comprising an oil tank shell, an upper frame at the upper end of the oil tank shell, a tank cover installed at the upper end of the upper frame, a leak-proof mechanism at the upper end of the oil tank shell, a connecting pipe on the inner wall of the oil tank shell, heat dissipation fins on the outer wall of the oil tank shell, a connecting frame installed on the lower wall of the oil tank shell, and a buffer mechanism on the lower wall of the connecting frame;

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model provides a technical solution: an anti-leakage oil tank for an electric furnace transformer, including an oil tank shell 1, an upper frame 2 at the upper end of the oil tank shell 1, a tank cover 3 installed at the upper end of the upper frame 2, an anti-leakage mechanism 4 at the upper end of the oil tank shell 1, a connecting pipe 5 on the inner wall of the oil tank shell 1, a heat sink 6 on the outer wall of the oil tank shell 1, a connecting frame 7 installed on the lower wall of the oil tank shell 1, and a buffer mechanism 8 on the lower wall of the connecting frame 7.

[0025] The anti-seepage mechanism 4 includes an anti-seepage groove 41, anti-seepage material 42, an upper sealing groove 43, an upper sealing ring 44, a side sealing groove 45, a side sealing ring 46, and a sealing block 47. The upper end of the tank shell 1 is provided with an anti-seepage groove 41, and the inner wall of the anti-seepage groove 41 is equipped with anti-seepage material 42. The upper wall of the upper end frame 2 is provided with an upper sealing groove 43, and the inner wall of the upper sealing groove 43 is equipped with an upper sealing ring 44. The inner side wall of the upper end frame 2 is provided with a side sealing groove 45, and the inner wall of the side sealing groove 45 is equipped with a side sealing ring 46. The lower wall of the tank cover 3 is provided with a sealing block 47.

[0026] Furthermore, the inner wall size of the upper sealing groove 43 matches the outer wall size of the upper sealing ring 44, and the inner wall size of the side sealing groove 45 matches the outer wall size of the side sealing ring 46. Through the setting of the anti-seepage groove 41, anti-seepage material 42, upper sealing groove 43, upper sealing ring 44, side sealing groove 45, side sealing ring 46 and sealing block 47, when using the transformer, the setting of the anti-seepage groove 41 firstly allows the anti-seepage material 42 to be filled between the inner shell and the outer shell of the tank shell 1, which can prevent oil from seeping from the weld gap of the tank shell 1 to a certain extent. Then, the side sealing ring 46 in the side sealing groove 45 will squeeze the side wall of the sealing block 47, and the tank cover 3 will squeeze the upper sealing ring 44 in the upper sealing groove 43, which can effectively prevent oil from leaking from the gap between the tank cover 3 and the upper frame 2.

[0027] Furthermore, the connecting pipe 5 passes through the oil tank shell 1 and connects to the heat sink 6. The heat sink 6 is evenly distributed on the outer wall of the oil tank shell 1. The connecting pipe 5 allows the oil in the oil tank shell 1 to enter the heat sink 6.

[0028] Furthermore, the connecting pipes 5 are evenly distributed on the inner wall of the tank shell 1, and the connecting frame 7 is symmetrically arranged about the central axis of the tank shell 1.

[0029] Furthermore, the buffer mechanism 8 includes a movable block 81, a movable groove 82, a storage block 83, a storage groove 84, a hydraulic damper 85, and a base plate 86. The lower wall of the connecting frame 7 is provided with a movable block 81, the bottom wall of the movable block 81 has a movable groove 82, the outer wall of the movable block 81 is provided with a storage block 83, the upper wall of the storage block 83 has a storage groove 84, the inner wall of the storage groove 84 is provided with a hydraulic damper 85, and the bottom wall of the storage block 83 is fixedly connected to the base plate 86. The buffer mechanism 8 is formed by the movable block 81, the movable groove 82, the storage block 83, and the storage groove 84. The arrangement of the storage slot 84, hydraulic damper 85, and base plate 86 causes some vibration during transformer operation. At this time, the oil tank shell 1 will transmit the force to the movable block 81 through the connecting frame 7, so that the movable block 81 receives a downward force. The two ends of the hydraulic damper 85 are connected to the movable slot 82 and the storage slot 84 respectively. In this way, the movable block 81 will press down on the hydraulic damper 85, and the hydraulic damper 85 can relieve the force. The movable block 81 slides up and down in the storage slot 84, which can reduce the vibration of the transformer and protect the transformer to a certain extent.

[0030] Furthermore, the outer wall dimensions of the movable block 81 match the inner wall dimensions of the storage slot 84. The movable block 81 is symmetrically arranged around the central axis of the fuel tank shell 1. The movable block 81 can be inserted into the storage slot 84.

[0031] Furthermore, the hydraulic dampers 85 are evenly distributed on the inner wall of the receiving groove 84.

[0032] Working principle: When using the transformer, the anti-seepage groove 41 firstly fills the space between the inner and outer shells of the tank shell 1 with anti-seepage material 42, which can prevent oil from seeping through the welded seams of the tank shell 1 to a certain extent. Then, the side sealing ring 46 in the side sealing groove 45 will squeeze the side wall of the sealing block 47, and the tank cover 3 will squeeze the upper sealing ring 44 in the upper sealing groove 43, which can effectively prevent oil from leaking through the gap between the tank cover 3 and the upper frame 2. When the transformer is operating, a certain amount of vibration will occur. At this time, the tank shell 1 will transmit the force to the movable block 81 through the connecting frame 7, so that the movable block 81 receives a downward force. The two ends of the hydraulic damper 85 are connected to the movable groove 82 and the receiving groove 84 respectively. In this way, the movable block 81 will press down on the hydraulic damper 85, and the hydraulic damper 85 can relieve the force. The movable block 81 slides up and down in the receiving groove 84, which can reduce the vibration of the transformer and protect the transformer to a certain extent.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
