Description

Technical Field

[0002] Box-type substations are key components of intelligent high-voltage power systems and are widely used in various outdoor and semi-outdoor environments. Their stable operation is crucial to ensuring the reliability and security of power supply. With the acceleration of urbanization and the continued growth of industrial and residential power demand, the number of box-type substations is increasing, and their application scenarios are becoming increasingly diverse, ranging from urban blocks and industrial parks to remote mountainous areas.

[0003] The box-type substation is equipped with switchgear, transformers, fuses and other equipment, which will generate a lot of heat during operation. In order to ensure the normal operation of various equipment in the box-type substation, it is necessary to install a temperature control device in the box-type substation.

[0004] For example, the utility model disclosed in announcement number CN209786605U discloses an energy-saving outdoor substation, which has an air conditioner installed inside the substation and vents on the side walls of the substation to achieve cooling of the box-type substation. In order to consider the rainproof performance of the box-type substation, it is usually necessary to reduce the inner diameter of the vents or set the vents as horizontal long holes with top shielding, such as louvers. However, reducing the inner diameter of the vents will reduce the ventilation efficiency of the box-type substation, and setting the horizontal long holes cannot effectively utilize the natural convection of air, resulting in the vents being unable to fully exert their heat dissipation effect, which is not conducive to improving the heat dissipation performance of the box-type substation.

[0048] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figure 1 As shown, a box-type substation of the present invention includes a cabinet frame 1 and a surrounding panel 2. The cabinet frame 1 is a frame structure with open sides, including a top plate, a bottom plate and a load-bearing beam between the top plate and the bottom plate. Various power distribution and control equipment such as switch cabinets, transformers, fuses and air conditioners are installed inside the cabinet frame 1. The cabinet frame 1 is open on the sides for entry and exit of operators and various equipment.

[0051] The enclosure 2 is used to block the open area around the cabinet frame 1 and protect the various equipment inside the cabinet frame 1. The enclosure 2 includes a wall panel fixed to the cabinet frame 1 and a door body detachably connected to the cabinet frame 1. When the box-type substation is in use, the enclosure 2 is fixed to the cabinet frame 1 to block the cabinet frame 1 and wrap the cabinet frame 1 to protect the various equipment inside the substation. When the box-type substation is in maintenance, the door body can be removed to allow operators and related equipment to enter and exit the substation.

[0052] like Figure 1 As shown, the enclosure 2 includes a plate body 21, a buckle box 22 and a baffle 23. The plate body 21 is fixedly arranged on the cabinet frame 1 and is sealed therewith. The plate body 21 can be a wall or a door body. An air hole 201 is opened in the plate body 21. The inside and outside of the cabinet frame 1 are connected through the air hole 201. The air hole 201 is a longitudinal long hole. When various equipment inside the cabinet frame 1 generates heat, the hot air will rise and flow to the outside of the cabinet frame 1 through the middle and upper part of the air hole 201, while the cold air outside the cabinet frame 1 flows to the inside of the cabinet frame 1 through the middle and lower part of the air hole 201, forming an air flow circulation on the vertical plane, thereby accelerating the dissipation of heat. The longitudinally arranged air hole 201 can increase the width of the air flow circulation, thereby effectively improving the heat dissipation capacity of the air hole 201; at the same time, the improvement of the heat dissipation capacity of the air hole 201 can also reduce the use of temperature control equipment such as air conditioners in the cabinet frame 1, thereby achieving a certain energy-saving and power-saving effect.

[0053] The buckle box 22 is fixedly arranged on the inner side of the plate body 21 and blocks the air hole 201. The buckle box 22 is provided with an air hole 202, which is connected to the air hole 201. One end of the baffle 23 is fixedly arranged on the side wall inside the air hole 201, and the end of the baffle 23 away from the air hole 201 is spaced apart in the buckle box 22. Both sides of the baffle 23 are also spaced apart from the buckle box 22. The air hole 202 is located on the side of the baffle 23 away from the air hole 201. Figure 5 As shown, the distance from the side of the air hole 202 away from the plate body 21 to the plate body 21 is a, and the distance from the end of the baffle 23 away from the plate body 21 to the plate body 21 is b. When a≤b, the baffle 23 will not block the air hole 202, but can also shield and protect the air hole 202 to prevent rainwater from flowing into the interior of the cabinet frame 1 through the air hole 202, thereby achieving a good rainproof effect and ensuring the normal operation of various equipment in the cabinet frame 1.

[0054] like Figure 5 As shown, two baffles 23 are provided in each air hole 201, and the two baffles 23 are relatively arranged on the two side walls of the air hole 201, the baffles 23 are perpendicular to the plate body 21, and two groups of air holes 202 are opened on the side wall of the buckle box 22, and the two groups of air holes 202 correspond one to one with the two baffles 23.

[0055] Preferably, the end of the baffle 23 connected to the plate body 21 is integrally formed on the side wall of the air hole 201, such as Figure 5 As shown, the two baffles 23 have the same shape and size, and the width of the air hole 201 is c, c=2·b. When processing the plate body 21 and the baffle 23, it is only necessary to Figure 25 The plate 21 is punched along the solid line path shown in Figure 25 The baffle 23 is punched and bent along the dotted line path in the figure, so that the air hole 201 and the baffle 23 can be processed and formed, which greatly improves the processing efficiency of the enclosure 2.

[0056] like Figure 7 As shown, the bottom side of the air hole 202 is located above the bottom side of the buckle box 22, thereby preventing rainwater from flowing into the cabinet frame 1 along the air hole 202 when it flows to the bottom side of the buckle box 22; the air hole 202 penetrates to the side of the buckle box 22 close to the plate body 21, which not only makes it convenient to process the air hole 202, but also reduces the area of ​​the buckle box 22 close to the plate body 21, which is beneficial to ensure the flatness of the buckle box 22 close to the plate body 21, avoids the formation of a gap between the buckle box 22 and the plate body 21, and forms a good sealing effect.

[0057] In order to improve the structural strength of the baffle 23, it is preferred that the top and bottom sides of the baffle 23 abut against the inner wall of the buckle box 22; and in order to allow the accumulated water in the buckle box 22 to be quickly drained, it is preferred that the bottom side of the buckle box 22 be inclined and flush with the bottom side of the air hole 201. Figure 8 As shown, a water leakage hole 208 is opened on the bottom side of the baffle 23 near one end of the plate body 21 to prevent water from accumulating on the side of the baffle 23 near the air hole 202.

[0058] Example 2

[0059] like Figure 9 As shown, the difference from Example 1 is that the shapes of the two baffles 23 are inconsistent, and the processing methods of the two baffles 23 are shown in FIG. Figure 10 ,along Figure 10 The plate 21 is punched along the solid line path shown in Figure 10 The dotted line path in the figure is used to bend the baffle 23, as shown in FIG. Figure 9 As shown, the baffle 23 manufactured by this processing method has a protruding structure at the local part away from the end of the plate body 21. The protruding structure is in contact with the inner wall of the buckle box 22 and can even be welded and fixed to the inner wall of the buckle box 22, thereby helping to improve the structural strength of the baffle 23.

[0060] The sum of the widths of the two baffles 23 at the same height is still equal to the width of the air hole 201. Figure 9As shown, the air hole 202 on the left side of this position is blocked by the protruding structure, while the air hole 202 on the right side does not have a protruding structure. Compared with Example 1, Figure 9 The width of the left baffle 23 is greater than Figure 5 The width of the left baffle 23, and Figure 9 The width of the middle right baffle 23 is less than Figure 5 The width of the middle right baffle 23, Figure 9 At the position shown, the ventilation effect of the left air hole 202 is reduced, while the ventilation effect of the right air hole 202 is improved, resulting in different ventilation and heat dissipation effects on the left and right sides of the buckle box 22. Therefore, in this embodiment, the position of the protruding structure can be adjusted according to the layout of various devices within the cabinet frame 1. The protruding structure is not installed in locations with a large number of installed devices or a greater heat dissipation effect is required, while the protruding structure is installed in locations with a small number of installed devices or a smaller heat dissipation effect is required, thereby improving the overall heat dissipation performance of the box-type substation.

[0061] Example 3

[0062] like Figure 11 As shown, the difference from Example 2 is that the processing method of the two baffles 23 is shown in Figure 11 ,along Figure 11 The plate 21 is punched along the solid line path shown in Figure 11 The dotted path in the figure is used to bend the baffle 23 so that the side of the baffle 23 away from the plate body 21 is curved. This structure can increase the adjustment range of the distance between the end of the baffle 23 away from the plate body 21 and the inner wall of the buckle box 22, thereby increasing the adjustment range of the heat dissipation performance of the air hole 202, making the heat dissipation effect of the box-type substation more in line with the needs, and further improving the overall heat dissipation performance of the box-type substation.

[0063] Example 4

[0064] like Figure 12 and Figure 22 As shown, the difference from Example 1 is that the bottom side of the buckle box 22 is horizontal, and the enclosure 2 further includes a blocking plate 24, a wedge block 25, a fixing screw 26 and a connecting plate 27.

[0065] like Figure 12 and Figure 14 As shown, the baffle 23 and the buckle box 22 are enclosed to form a flow channel 203, and the blocking plate 24 is rotatably set in the buckle box 22. By rotating the blocking plate 24, the flow channel 203 can be blocked, so that the air hole 201 loses its heat dissipation ability; in strong wind weather, sandstorm weather or severe rain and snow weather, the blocking plate 24 is used to block the flow channel 203, which can prevent excessive wind, sandstorms or rain and snow from entering the cabinet frame 1, so as to protect various equipment inside the cabinet frame 1.

[0066] The wedge 25 is used to realize the automatic control of the blocking plate 24. It is a counterweight component and its weight can be adjusted by replacing the material or the internal filling. Figure 17 As shown, the wedge block 25 is slidably disposed on the buckle box 22 and abuts against the upper end of the blocking plate 24 away from the air hole 201, and the lower end of the wedge block 25 close to the plate body 21 is inclined; Figure 12 and Figure 13 As shown, in the natural state, the wedge 25 is affected by its own gravity to press the blocking plate 24 away from the side of the plate 21, so that the blocking plate 24 presses against the inner wall of the buckle box 22. At this time, the blocking plate 24 does not block the flow channel 203, so that the heat inside the cabinet frame 1 can be discharged to the outside; Figure 14 and Figure 15 As shown, when strong wind, dust or rain and snow exert a large force on the side of the blocking plate 24 close to the air hole 201, the blocking plate 24 rotates and pushes the wedge block 25 to lift until the blocking plate 24 pushes against the baffle 23 and blocks the flow channel 203, thereby preventing strong wind, dust or rain and snow from entering the interior of the cabinet frame 1.

[0067] like Figure 16 As shown, the side of the blocking plate 24 close to the air hole 201 includes a first arc segment 241, a second arc segment 242 and a straight segment 243. The second arc segment 242 is arranged between the first arc segment 241 and the straight segment 243 and is continuously arranged therewith. The end of the first arc segment 241 close to the second arc segment 242 is tangent to the end of the second arc segment 242 close to the first arc segment 241. The first arc segment 241 and the second arc segment 242 are used to guide the air, and the straight segment 243 is used to abut against the buckle box 22 or the baffle 23 to realize the on-off control of the flow channel 203.

[0068] The second arc segment 242 and the first arc segment 241 are both concave, and the cross section of the second arc segment 242 away from the end of the first arc segment 241 is the airflow surface; Figure 12 As shown, the dotted line position is one of the air flow surfaces. In the natural state, the air flow surface is located in the flow channel 203 and does not intersect with the baffle 23, thereby guiding the air flow to the flow channel 203 and accelerating the flow efficiency of the gas; Figure 14 As shown, the dotted line position is one of the air flow surfaces. When the side of the blocking plate 24 close to the air hole 201 is subjected to a larger force, the air flow surface intersects with the side of the baffle 23 away from the air hole 202, guiding the air flow to blow toward the baffle 23, thereby forming a vortex airflow between the two baffles 23, avoiding the air flow from blowing to the connection position between the blocking plate 24 and the baffle 23, and improving the closed sealing of the flow channel 203.

[0069] The portion of the blocking plate 24 on the side away from the air hole 201 corresponding to the second arc segment 242 and the first arc segment 241 is planar, so that it can slide with the wedge block 25 more stably.

[0070] like Figure 13 As shown, the two blocking plates 24 are cross-arranged to enhance the connection tightness and structural strength between the two to better resist external forces.

[0071] In hot weather, to cool down various devices inside the cabinet frame 1, temperature control equipment such as air conditioning should be operated separately, and flow channel 203 should be blocked to prevent cold air inside the cabinet frame 1 from overflowing the cabinet frame 1 along the flow channel 203. The provision of fixing screws 26 allows for active adjustment of the position of wedge block 25. Preferably, the wedge block 25 and the blocking plate 24 are connected by magnetic attraction. Actively moving the wedge block 25 upward can drive the blocking plate 24 to rotate, thereby achieving full or partial closure of the flow channel 203.

[0072] like Figure 17 As shown, a slide 204 is provided on the top side of the buckle box 22, the slide 204 is communicated with the interior of the buckle box 22, and the wedge 25 is slidably set in the slide 204, and the fixing screw 26 is connected to the wedge 25 by threaded fitting and abuts against the buckle box 22; when the fixing screw 26 is loosened so that it does not abut against the buckle box 22, the wedge 25 can be slid, and when the fixing screw 26 is tightened so that it abuts against the buckle box 22, the wedge 25 can be fixed.

[0073] In order to facilitate the manipulation of the fixing screw 26, the slide 204 is allowed to pass through the side of the buckle box 22 away from the plate body 21. The inner diameter of the slide 204 close to the plate body 21 is larger than the inner diameter of the end away from the plate body 21. The wedge block 25 is slidably set in the slide 204 at the end close to the plate body 21, and the screw part of the fixing screw 26 is slidably set in the slide 204 at the end away from the plate body 21. The screw head part of the fixing screw 26 is abutted against the side of the buckle box 22 away from the plate body 21; when loosening the fixing screw 26, the sliding of the fixing screw 26 can drive the wedge block 25 to slide.

[0074] In order to improve the heat dissipation performance of the box-type substation, it is preferred to set the air holes 201, buckle boxes 22, wedge blocks 25 and fixing screws 26 in multiple numbers, and make the multiple air holes 201, multiple buckle boxes 22, multiple wedge blocks 25 and multiple fixing screws 26 correspond to each other one by one.

[0075] When actively adjusting the wedge blocks 25 , all or most of the wedge blocks 25 are usually adjusted uniformly, and the connecting plate 27 plays a role in linking the multiple wedge blocks 25 to improve the adjustment efficiency of the wedge blocks 25 .

[0076] like Figure 20 and Figure 21As shown, a plurality of assembly slots 205 are provided on the connecting plate 27, and the assembly slots 205 extend to the top side of the connecting plate 27. A clamping slot 206 is provided on the side of the connecting plate 27 away from the plate body 21, and a limiting slot 207 is provided on the side of the connecting plate 27 close to the plate body 21. The clamping slot 206 is hexagonal in shape, which is consistent with the specifications of the screw head part of the fixing screw 26. The limiting slot 207 is circular in shape, and the fixing screw 26 is slidably set in the assembly slot 205 and can resist the connecting plate 27. The clamping slot 206 is clamped with the fixing screw 26, and the limiting slot 207 is rotatably connected with the fixing screw 26, and the multiple clamping slots 206, the multiple limiting slots 207, the multiple fixing screws 26 and the multiple assembly slots 205 correspond one to one.

[0077] Since the assembly slot 205 penetrates to the top side of the connecting plate 27 , the fixing screw 26 located at the bottom can be abutted and fixed to the connecting plate 27 , thereby not affecting the up and down adjustment of other fixing screws 26 .

[0078] Since the fixing screw 26 is engaged with the slot 206, Figure 18 、 Figure 23 and Figure 24 As shown, when multiple fixing screws 26 move synchronously, the screw head portion of one of the fixing screws 26 can be abutted against the limiting groove 207, while the screw head portions of the remaining fixing screws 26 can be abutted against the card slot 206. At this time, the positions and rotation angles of the multiple fixing screws 26 connected to the multiple card slots 206 remain uniform and cannot be rotated. Only the fixing screws 26 connected to the limiting groove 207 need to be rotated to loosen the multiple fixing screws 26 to achieve the synchronous up and down movement of the multiple wedge blocks 25. Then, the fixing screws 26 connected to the limiting groove 207 can be rotated to fix the multiple fixing screws 26 and the multiple wedge blocks 25.

[0079] Figure 2 and Figure 4 Four air holes 201 are shown in the figure, and the four air holes 201 correspond to the air holes 201 in Example 1, Example 2, Example 3 and Example 4 from left to right. In order to adapt to the layout of various equipment in the cabinet frame 1 and the operating conditions of the device, in actual application, only one embodiment can be set on each plate 21, or multiple embodiments can be used in combination.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
