Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power boxes for high-voltage electric power engineering, and more particularly to a power box for high-voltage electric power engineering. Background Art
[0002] In the current high-voltage power engineering field, power boxes, as key equipment, face a series of severe challenges and limitations. These problems not only affect the performance and life of the equipment, but also increase the difficulty and cost of maintenance, and may even endanger the safety and stability of the entire power system.
[0003] First, the heat dissipation problem of internal components of the power box is a long-standing challenge that is difficult to completely solve. High-voltage power equipment generates a large amount of heat during operation. This heat mainly comes from the Joule heat generated when the current passes through the conductor, the iron loss and copper loss of the transformer and reactor, and the power consumption of various electronic control devices. If this heat cannot be effectively dissipated, it will lead to a series of serious consequences. For example, excessively high temperatures will accelerate the aging of insulation materials and reduce the service life of the equipment; it may also cause thermal expansion of metal parts, affecting the fitting accuracy of precision components; more seriously, overheating may cause electrical fires or cause sudden failure of equipment. These problems will not only affect the normal operation of individual equipment, but may also cause instability of the entire power system and even trigger large-scale power outages.
[0004] Secondly, in order to solve the heat dissipation problem, ventilation devices are widely used in the design of power boxes. However, this solution itself brings new challenges. In high-voltage power environments, the air often contains a large amount of dust, metal particles and other pollutants. If these impurities enter the power box directly, they will cause serious damage to the internal precision components. Therefore, installing a filter plate at the air inlet has become a necessary measure. However, the use of the filter plate has caused a series of maintenance problems. As the use time increases, the filter plate will gradually be blocked by dust and impurities, reducing the ventilation efficiency or even completely losing the filtering function. This requires regular cleaning or replacement of the filter plate. However, the filter plate installation design in the existing technology is often ill-considered, and the disassembly and installation process is complicated and cumbersome. This design not only increases maintenance time and cost, but may also damage other components due to improper operation.
[0005] In addition, in order to cope with the difficulty of replacing the filter plate, some equipment manufacturers have indeed tried to design some quick installation and disassembly mechanisms. However, these fixing devices often have problems with overly simple structures and immature designs. For example, some simple snap-on designs are easy to operate, but they are prone to loosening or deformation after long-term use. This loosening not only affects the filtering effect, but may also cause the filter plate to fall off during the operation of the equipment. After the filter plate falls off, it may block the ventilation duct and seriously affect the heat dissipation effect. Utility Model Content

[0035] In this embodiment, when the filter plate 3 needs to be maintained or replaced, the bin door 21 is first opened, and then the adapter set 14 is rotated. The adapter set 14 will drive the above-opened give way groove 16 to move. When the give way groove 16 moves to the position corresponding to the ejector rod 15, the matching sleeve 8 is pushed. The matching sleeve 8 will drive the ejector rod 15 to pass through the give way groove 16, and the matching sleeve 8 will cooperate with the adapter set 14 to squeeze the push spring 18 set on the outside of the ejector rod 15.

This ensures a stable connection and prevents the structure from loosening or even falling off.
[0036] See also Figure 1 and Figure 2 As a further embodiment of the entire device: a box door 20 is movably provided on one side of the power box 1, and a compartment door 21 is movably provided on one side of the installation compartment 2.

[0038] An air outlet 25 is formed at the top of the power box 1 .
[0039] A baffle 26 is installed above the power box 1 .
[0040] More specifically, when the device is in daily use, the setting of the baffle 26 can effectively prevent rainwater from entering the power box 1 through the air outlet 25. When the temperature inside the device is high, the motor 23 is turned on, and the motor 23 drives the fan blades 24 to rotate, and then the outside air is drawn into the ventilation pipe 4. Before the air enters the ventilation pipe 4, it will first be filtered by the filter plate 3. The filter plate 3 can effectively block and filter solid particulate matter. Then the air will enter the ventilation pipe 4, and then pass through the fan blades 24 and be blown into the power box 1 to dissipate heat to the various components inside the power box 1.

[0041] In summary, when the entire device is in use or running: when the filter plate 3 needs to be maintained or replaced, first open the compartment door 21, then rotate the adapter set 14, the adapter set 14 will drive the above-opened give way slot 16 to move, when the give way slot 16 moves to the position corresponding to the ejector rod 15, push the matching sleeve 8, the matching sleeve 8 will drive the ejector rod 15 to pass through the give way slot 16, and the matching sleeve 8 will cooperate with the adapter set 14 to squeeze the push spring 18 set on the outside of the ejector rod 15, and at the same time the matching sleeve 8 will drive the through slot 7 to move, and then the through slot The inner wall of 7 will squeeze one side of the matching plate 5, so that the matching plate 5 drives the connecting plate 11 to rotate along the fixed axis 10, so that the connecting plate 11 gradually turns out from the connecting groove 13, and at the same time, the connecting plate 11 will gradually enter the movable groove 9. When the push spring 18 is squeezed to the limit, the connecting plate 11 just completely enters the movable groove 9. At this time, the connecting plate 11 is no longer engaged with the connecting groove 13. Then, pull the connecting sleeve 6 to one side to remove the connecting sleeve 6 from the outside of the connecting rod 12, and then remove the connecting rod from the outside of the power box 1. 12 is pulled out, and then the filter plate 3 is removed. When the maintenance and replacement of the filter plate 3 is completed, the filter plate 3 after maintenance and replacement is reinstalled to the corresponding position, and then the connecting rod 12 is passed through the filter plate 3 and the side wall of the installation chamber 2 from the outside, and then the connecting sleeve 6 is sleeved to the outside of the connecting rod 12 from the other side, and then the matching sleeve 8 is loosened, and the push spring 18 pushes the matching sleeve 8 to reset, and then the matching sleeve 8 drives the push rod 15 to reset, and then the matching sleeve 8 will drive the through slot 7 to move, and then the other inner wall of the through slot 7 will contact the other side of the matching plate 5 The side is squeezed so that the matching plate 5 drives the connecting plate 11 to rotate and reset along the fixed axis 10. When the push spring 18 is completely reset, the connecting plate 11 enters the connecting groove 13 and forms a locking relationship with the connecting groove 13. Then the adapter sleeve 14 is rotated, and the adapter sleeve 14 drives the yield groove 16 to move to a position that does not correspond to the push rod 15. Then the push rod 15 will cooperate with the adapter sleeve 14 to form a limit for the matching sleeve 8 to prevent the matching sleeve 8 from moving, thereby ensuring a stable connection relationship and preventing the structure from loosening or even falling off easily.
[0042] When the device is in daily use, the setting of the baffle 26 can effectively prevent rainwater from entering the power box 1 through the air outlet 25. When the temperature inside the device is high, the motor 23 is turned on, and the motor 23 drives the fan blades 24 to rotate, and then the outside air is drawn into the ventilation pipe 4. Before the air enters the ventilation pipe 4, it will first be filtered by the filter plate 3. The filter plate 3 can effectively block and filter solid particulate matter. Then the air will enter the ventilation pipe 4 and be blown into the power box 1 after passing through the fan blades 24, so as to dissipate heat for the various components inside the power box 1. At the same time, the hot air accumulated in the power box 1 will be discharged from the air outlet 25 opened at the top of the power box 1, thereby realizing effective air circulation and accelerating the heat dissipation efficiency of the equipment.
