[0002] Electricity is an important energy source in daily life, and electrical energy is used as a power source. Substations are a type of equipment frequently used in power systems. In the power industry, electrical components are often installed and placed in substations. If the lines in a substation break or short-circuit due to an accident, it can cause serious economic losses.

[0003] If the external air is humid, the intrusion of external moisture into the existing transformer cabinet enclosure can have a significant impact on the electrical components inside the cabinet, leading to accidents such as line failures and thus lacking a certain level of safety. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a transformer cabinet housing with good sealing performance, which has the advantage of drying external air and solves the problem of external moisture easily entering the housing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a transformer cabinet housing with good sealing performance, comprising a main body assembly; the main body assembly includes a transformer cabinet shell, the front surface of which is hinged with a rotating door; a sealing strip, fixedly connected to the inner wall of the transformer cabinet shell; a drying assembly is provided on the transformer cabinet shell, the drying assembly comprising: a mounting frame, disposed on the inner wall of the transformer cabinet shell; a fixing block, inserted into the mounting frame, and having a limiting groove at its top; a plate, fixedly connected to the rear surface of the fixing block; a housing, fixedly connected to the top of the mounting frame; a limiting block, penetrating the plate and inserted into the limiting groove at the top of the fixing block; a movable plate, fixedly connected to the outer wall of the limiting block and slidably connected to the inner wall of the housing; and springs, symmetrically arranged on the movable plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a transformer cabinet housing with good sealing performance, which has the following advantages:

[0015] This invention has the advantage of drying external air. When the outside air is humid and moisture enters the transformer cabinet casing through the ventilation opening, the panel, made of a honeycomb module of porous silica and other moisture-absorbing materials, can absorb moisture from the air while allowing normal airflow. This prevents moisture from entering the transformer cabinet casing and affecting the internal components. When the panel has been used for a long time and its moisture-absorbing and drying function decreases, the operator can pull the limit block to release the panel and then remove it for replacement, thus solving the problem of external moisture easily entering the casing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Example 1

[0027] See Figure 1-4 A well-sealed transformer cabinet housing includes a main body assembly 1; the main body assembly 1 includes a transformer cabinet shell 11, with a rotating door 12 hinged to its front surface; a sealing strip 13 fixedly connected to the inner wall of the transformer cabinet shell 11; a drying assembly 2 is provided on the transformer cabinet shell 11, the drying assembly 2 including: a mounting frame 21, provided on the inner wall of the transformer cabinet shell 11; a fixing block 22, inserted into the mounting frame 21, with a limit groove on its top; a plate 23 fixedly connected to the rear surface of the fixing block 22; a housing 24 fixedly connected to the top of the mounting frame 21; a limiting block 25, penetrating the plate 23 and inserted into the limit groove on the top of the fixing block 22; a moving plate 26 fixedly connected to the outer wall of the limiting block 25 and slidably connected to the inner wall of the housing 24; springs 27 symmetrically arranged on the moving plate 26; a filter plate 4 is provided on the mounting frame 21; and a damper 5 is provided on the moving plate 26.

[0028] When ready for use, the operator places the transformer cabinet housing 11 in the designated position. When water accumulates at the bottom of the transformer cabinet housing 11, the sealing strip 13 is used to seal the gap between the rotating door 12 and the transformer cabinet housing 11 to prevent water from entering the transformer cabinet housing 11 and improve its sealing performance. When the outside air is humid and moisture enters the transformer cabinet housing 11 through the ventilation opening, the panel 23, made of a honeycomb module of porous silica and other moisture-absorbing materials, can absorb the moisture in the air while allowing normal airflow, preventing moisture from entering the transformer cabinet housing 11 and affecting the internal components. When the moisture-absorbing and drying function of the panel 23 decreases after prolonged use, the operator pulls the limit block 25 on the housing 24, causing the limit block 25 to move the moving plate 26. By squeezing multiple springs 27, the limiting block 25 is moved out of the limiting groove on the fixed block 22, thus removing the limiting fixation of the fixed block 22. Subsequently, the operator can remove the fixed block 22 along with the plate 23 for replacement, improving the practicality of the device. The filter plate 4 on the mounting frame 21 allows air to be filtered before it passes through the plate 23 for drying, preventing a large amount of dust from entering the device. When the device is subjected to external force and shakes, the moving plate 26 shakes through the springs 27. At this time, the damper 5 moves back and forth with the vibration structure through the damping rod, driving the piston to move in the cylinder filled with hydraulic oil. The small holes or gaps on the piston force the hydraulic oil to pass through, generating viscous resistance and internal friction between fluid molecules, converting the vibration kinetic energy into heat energy for dissipation. This prevents the limiting block 25 from shaking excessively and moving out of the fixed block 22, affecting the fixing effect, thereby improving the stability of the device.

[0029] Example 2

[0030] See Figure 1-4 Based on Embodiment 1, a disassembly function has been added;

[0031] The transformer cabinet housing 11 is provided with a disassembly assembly 3, which includes: a mounting plate 31, which is fixedly connected to the top of the mounting frame 21; bolts 32, which penetrate the mounting frame 21 and are inserted into the inner side wall of the transformer cabinet housing 11, and are threadedly connected to both the mounting frame 21 and the transformer cabinet housing 11, and multiple bolts are provided; a pull plate 6 is fixedly connected to the top of the limiting block 25; and an inclined surface is provided on the limiting block 25.

[0032] After the operator unscrews the multiple bolts 32, the mounting plate 31 is removed from the fixing, thereby removing the fixing of the mounting frame 21. This allows the operator to remove the mounting frame 21 for maintenance or replacement, and also facilitates the cleaning of the filter plate 4, improving the practicality of the device. The operator can move the limiting block 25 simultaneously by pulling the pull plate 6, thus avoiding the inconvenience of the operator pulling the relatively smooth surface of the limiting block 25, thereby improving the convenience of the device. When the operator installs the plate 23, the plate 23 presses against the inclined surface of one side of the limiting block 25. At this time, the limiting block 25 automatically moves outward from the mounting frame 21 without the operator having to pull the limiting block 25 by hand, thereby improving the operator's work efficiency.

[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.
