[0001] This application relates to the field of substation technology, and more specifically, to a prefabricated substation. Background Technology

[0053] The term "perpendicular" in this application refers to "basic perpendicularity" in actual operation. "Basic perpendicularity" can be understood as perpendicularity with a certain degree of error.

[0054] This application discloses a prefabricated substation that enables low-cost arc extinguishing of switchgear.

[0055] As shown in Figures 1 and 2, the prefabricated substation disclosed in this application includes: a container 100, a switchgear 200, and an arc venting channel 300.

[0056] The container 100 may include a base 110. The base 110 is used to support the various electrical equipment of the prefabricated substation. The switchgear 200 may be a ring main unit or other switchgear 200; this application embodiment does not limit the type of switchgear 200.

[0057] The switch cabinet 200 is mounted on the base 110. The distribution direction of the switch cabinet 200 and the base 110 can be referred to as the first direction, and the side of the base 110 on which the switch cabinet 200 is mounted in the first direction can be referred to as the top side of the base 110.

[0058] The switchgear 200 is equipped with a pressure relief port 201, which can be one or more. The pressure relief port 201 is used for arc venting, specifically, arc venting is achieved through arc-induced pressure relief. Arc-induced pressure relief refers to the process of safely releasing the enormous energy and pressure generated by an electric arc to the external environment when an internal fault occurs in a prefabricated substation or similar facility, in order to prevent equipment damage and ensure the safety of workers.

[0059] Since the switch cabinet 200 is located on the top side of the base 110 in the first direction, the pressure relief port 201 is also located on the top side of the base 110 in the first direction.

[0060] The specific location of the pressure relief port 201 on the switch cabinet 200 is selected according to the actual situation. For example, it can be designed according to the location of the arc venting channel 300. This application embodiment does not limit this.

[0061] For example, continuing to refer to Figures 1 and 2, the switch cabinet 200 has a top plate 202, a bottom plate 203, and a side plate 204. The top plate 202 and the bottom plate 203 are distributed along a first direction, and the bottom plate 203 is connected to the base 110. In the first direction, the side plate 204 is located between the top plate 202 and the bottom plate 203. The side plate 204 connects the top plate 202 and the bottom plate 203.

[0062] The cabinet side panels 204 mentioned above can be four, namely a first side panel 204a, a second side panel 204b, a third side panel 204c, and a fourth side panel 204d. The first side panel 204a and the second side panel 204b are distributed opposite each other along a second direction, and the third side panel 204c and the fourth side panel 204d are distributed opposite each other along a third direction; both the third side panel 204c and the fourth side panel 204d are located between the first side panel 204a and the second side panel 204b. There is an angle between the third direction and the second direction; for example, the second direction is perpendicular to the third direction; the first direction is perpendicular to the plane containing both the second direction and the third direction.

[0063] The pressure relief port 201 can be located on the cabinet bottom plate 203. Of course, as shown in Figure 9, the pressure relief port 201 can also be located on the second side plate 204b or other cabinet side plates 204.

[0064] It should be noted that when the switch cabinet 200 has a cabinet door on the first side panel 204a, the pressure relief port 201 is usually not located on the first side panel 204a. This can be understood as the cabinet door and the pressure relief port 201 being located on different cabinet side panels 204.

[0065] The container 100 has an arc-venting zone 500 on the top side of the base 110. The arc-venting zone 500 is an area where safe arc venting can be performed. For example, the arc-venting zone 500 is connected to a safe and open external environment to achieve safe discharge of electric arc and pressure. This external environment can be understood as the external environment of the container 100 or the external environment of the prefabricated substation.

[0066] Since the arc-dissipating zone 500 is located on the top side of the base 110, the position of the arc-dissipating zone 500 can be further defined. As shown in Figures 1 and 2, in the second direction, the arc-dissipating zone 500 can be set on one side of the switch cabinet 200.

[0067] As shown in Figures 5 and 6, in the second direction, the arc-dissipating area 500 is located on one side of the switch cabinet 200; and in the third direction, the arc-dissipating area 500 is located on one side of the switch cabinet 200.

[0068] As shown in Figures 7 and 8, in the third direction, the arc-extinguishing zone 500 can be located on one side of the switchgear 200. As shown in Figure 9, in the first direction, the arc-extinguishing zone 500 can be located on the side of the switchgear 200 away from the base 110; in the second direction, the arc-extinguishing zone 500 can be located on one side of the switchgear 200. Of course, the arc-extinguishing zone 500 can also be located on the side of the switchgear 200 away from the base 110 in the first direction, or the arc-extinguishing zone 500 can also be located on one side of the switchgear 200 in the second direction.

[0069] In this embodiment, the release direction and release path of the electric arc and pressure within the arc relief zone 500 are selected according to the actual situation, and this embodiment does not limit this.

[0070] Referring again to Figures 1 and 2, the inlet 300a of the arc venting channel 300 is connected to the pressure relief port 201, and the outlet 300b of the arc venting channel 300 is connected to the arc venting zone 500. The arc venting channel 300 is used to guide the direction of the electric arc and pressure, so that when the switchgear 200 is venting pressure during arcing, the electric arc and pressure are guided to the arc venting zone 500 through the arc venting channel 300.

[0071] Seals can also be installed between the pressure relief port 201 and the channel inlet 300a, and between the channel outlet 300b and the arc relief zone 500, to prevent electric arc and pressure leakage.

[0072] It should be noted that since the number of pressure relief ports 201 on the switch cabinet 200 can be one or more, the arc venting channel 300 can be one or more corresponding to each pressure relief port 201, or the arc venting channel 300 can be one and connected to each pressure relief port 201, in order to simplify the structure.

[0073] As shown in Figure 3, an arc-extinguishing mechanism 400 is provided at the channel entrance 300a of the arc-extinguishing channel 300; or, as shown in Figure 4, an arc-extinguishing mechanism 400 is provided at the channel exit 300b of the arc-extinguishing channel 300. The arc-extinguishing mechanism 400 may include a pressure relief plate, a pressure relief door, or other arc-extinguishing mechanisms 400, which are not limited in this embodiment.

[0074] During normal use, the arc extinguishing mechanism 400 is in the closed state and can close the arc extinguishing channel 300 to prevent the switch cabinet 200 from being directly connected to the arc extinguishing area 500, thus affecting its normal function. When arc extinguishing pressure is required, the arc extinguishing mechanism 400 opens due to the huge arc extinguishing pressure, and the electric arc and arc extinguishing pressure can be released through the arc extinguishing channel 300 to achieve arc extinguishing pressure.

[0075] In practice, arc venting mechanisms 400 can be provided at both the channel inlet 300a and the channel outlet 300b of the arc venting channel 300; or, neither the channel inlet 300a nor the channel outlet 300b of the arc venting channel 300 can be provided with arc venting mechanisms 400.

[0076] The channel outlet 300b of the arc venting channel 300 may or may not be connected to the external environment. When the switch cabinet 200 is an outdoor switch cabinet 200b, the channel outlet 300b of the arc venting channel 300 is more likely to be connected to the external environment.

[0077] When the outlet 300b of the arc-venting channel 300 is connected to the external environment, and the arc-venting area 500 is also connected to the external environment, or the arc-venting area 500 is part of the external environment, there is a risk of rainwater entering the arc-venting channel 300. As shown in Figure 5, a drainage hole 340 can be opened at the bottom end or other location of the arc-venting channel 300 to drain accumulated water and prevent backflow of water into the switch cabinet 200. This application embodiment does not limit the shape or number of drainage holes 340.

[0078] It should be noted that, in the first direction, the side of the base 110 away from the switch cabinet 200 is the bottom side of the base 110; the bottom end of the arc venting channel 300 can be understood as: in the first direction, the end of the arc venting channel 300 close to the bottom side of the base 110.

[0079] The specific location of the drain hole 340 in the arc venting channel 300 is selected according to the actual situation, as long as the water in the arc venting channel 300 is drained.

[0080] As mentioned above, the channel outlet 300b of the arc venting channel 300 can be connected to the external environment. In this case, as shown in Figure 5, a protective net 330 is provided at the channel outlet 300b of the arc venting channel 300. The protective net 330 is used to reduce the probability of foreign objects entering the arc venting channel 300, thereby reducing the probability of foreign objects causing blockage of the arc venting channel 300, and thus reducing the impact on arc venting.

[0081] The arc venting channel 300 may be provided with both a water leakage hole 340 and a protective net 330, or only one of the water leakage hole 340 and the protective net 330 may be provided. This application embodiment does not limit this.

[0082] It should be noted that when an arc-venting mechanism 400 is installed at the channel exit 300b, a protective net 330 may or may not be installed at the channel exit 300b.

[0083] When the channel outlet 300b of the arc venting channel 300 can be connected to the external environment, the channel outlet 300b and the pressure relief port 201 are arranged flush in the first direction, or the channel outlet 300b of the arc venting channel 300 is farther away from the base 110 than the pressure relief port 201 in the first direction. The relative position of the channel outlet 300b and the pressure relief port 201 in the first direction is not limited.

[0084] Compared to related technologies where the switchgear 200 is downward-facing and an arc-venting space is set on the foundation, this embodiment of the application arranges the arc-venting area 500 on the top side of the base 110 and safely guides the arc and pressure to the arc-venting area 500 through the arc-venting channel 300, thereby achieving arc venting to the top side of the base 110. This avoids the need to design an arc-venting space on the foundation due to downward arc venting, thus reducing arc venting costs and saving space at the bottom of the prefabricated substation.

[0085] The shapes of the arc venting channel 300 and the pressure relief port 201 are not limited in the embodiments of this application.

[0086] In this embodiment, at least a portion of the arc-venting zone 500 is located further away from the base 110 than the pressure relief port 201 along the first direction. It is understood that, along the first direction, the pressure relief port 201 is located between at least a portion of the arc-venting zone 500 and the base 110. This allows arc venting to occur at a location further away from the base 110 than the pressure relief port 201, thus avoiding the operator's work area and improving the safety of the prefabricated substation.

[0087] For example, as shown in Figure 1, along the first direction, the entire arc-venting zone 500 is farther away from the base 110 than the pressure relief port 201. In this way, the entire arc-venting zone 500 can be as far away from the base 110 as possible, and can be far away from the operating area of ​​the operators, thus improving the safety of the prefabricated substation; or, as shown in Figure 9, along the first direction, a portion of the arc-venting zone 500 is farther away from the base 110 than the pressure relief port 201.

[0088] Of course, along the first direction, the maximum distance between the arc relief zone 500 and the base 110 can also be equal to the distance between the pressure relief port 201 and the base 110.

[0089] When at least a portion of the arc-venting zone 500 is farther from the base 110 than the pressure relief port 201 along the first direction, as shown in Figure 1, the distance between the channel outlet 300b of the arc-venting channel 300 and the base 110 in the first direction can be equal to the distance between the pressure relief port 201 and the base 110 in the first direction. This can be understood as the pressure relief port 201 and the channel outlet 300b being flush with each other in the first direction. This allows the channel outlet 300b and the channel inlet 300a of the arc-venting channel 300 to also be flush with each other in the first direction, simplifying the structure of the arc-venting channel 300.

[0090] As shown in Figures 5 and 6, when at least a portion of the arc-extinguishing zone 500 is farther from the base 110 than the pressure relief port 201 along the first direction, the channel outlet 300b of the arc-extinguishing channel 300 can also be farther from the base 110 than the pressure relief port 201 along the first direction. This can be understood as the distance between the channel outlet 300b and the base 110 in the first direction being greater than the distance between the pressure relief port 201 and the base 110 in the first direction. In this way, the arc and pressure are guided to the top side of the base 110 through the arc-extinguishing channel 300 and safely discharged at the arc-extinguishing zone 500. This facilitates arc extinguishing at a location in the arc-extinguishing zone 500 far from the base 110, and also keeps it away from the operator's area, improving the safety of the prefabricated substation.

[0091] In this embodiment of the application, the distance between the arc venting zone 500 and the base 110 in the first direction, and the distance between the pressure relief port 201 and the base 110 in the first direction can also be equal. In this case, the pressure relief port 201 can be set on the cabinet side plate 204 of the switch cabinet 200.

[0092] In this embodiment, at least a portion of the arc-venting channel 300 may be constructed on the base 110. This configuration is applicable to scenarios where the switch cabinet 200 includes an indoor switch cabinet 200a. It is also applicable to scenarios where the switch cabinet 200 includes an outdoor switch cabinet 200b.

[0093] As shown in Figures 1 and 2, the entire arc venting channel 300 is constructed on the base 110. This makes full use of the space within the base 110, reduces the occupation of other spaces, and helps to reduce the overall volume of the prefabricated substation. It also simplifies the structure of the arc venting channel 300 and facilitates its layout.

[0094] Since the entire arc venting channel 300 is constructed on the base 110, the channel inlet 300a and channel outlet 300b of the arc venting channel 300 are also constructed on the base 110. To facilitate communication between the channel inlet 300a and the pressure relief port 201, the pressure relief port 201 can be located at one end of the switchgear 200 located on the base 110. This can be understood as the pressure relief port 201 being located on the cabinet bottom plate 203 of the switchgear 200. Since the cabinet bottom plate 203 of the switchgear 200 faces directly towards the base 110, for example, if the cabinet bottom plate 203 is directly attached to the base 110, the pressure relief port 201 can be directly connected to the channel inlet 300a, resulting in a simple structure. Of course, the pressure relief port 201 can also be indirectly connected to the channel inlet 300a.

[0095] To facilitate arc venting, in the second direction, the channel outlet 300b of the arc venting channel 300 is located on one side of the switchgear 200.

[0096] Of course, in order to facilitate arc extinguishing, the channel outlet 300b of the arc extinguishing channel 300 can also be located on the side of the switchgear 200 in the third direction; or, the channel outlet 300b of the arc extinguishing channel 300 can also be located on the side of the switchgear 200 in the third direction and on the side of the switchgear 200 in the second direction.

[0097] It should be noted that the position of the arc-venting zone 500 can be set according to the channel outlet 300b, and this application embodiment does not limit it in this way.

[0098] The entire arc-venting channel 300 is constructed on the base 110. In the event of arc venting, there is still a safety hazard for workers when they approach the area where the channel outlet 300b is located. Therefore, a portion of the arc-venting channel 300 is constructed on the base 110, while another portion extends towards the top side of the base 110 to place the channel outlet 300b in a safe area on the top side that is inaccessible to workers.

[0099] As shown in Figures 5 and 6, the arc-venting channel 300 includes a first channel 310 and a second channel 320. The first channel 310 extends along a second direction and a third direction, while the second channel 320 extends along the first direction. In practice, the extension direction of the first channel 310 can also be the second direction or the third direction, or it can extend along other directions within the plane containing the third and second directions (excluding the second and third directions). The extension direction of the second channel 320 can also have an angle with the first direction, as long as the second channel 320 extends towards the top side of the base 110.

[0100] It should be noted that the extension direction of the first channel 310 refers to the flow direction of the first channel 310, and the extension direction of the second channel 320 refers to the flow direction of the second channel 320.

[0101] The first channel 310 is constructed on the base 110, and the first inlet 310a of the first channel 310 is connected to the pressure relief port 201. The second channel 320 is distributed on the top side of the base 110. The second inlet 320a of the second channel 320 is connected to the first outlet 310b of the first channel 310. The second outlet 320b of the second channel 320 is the channel outlet 300b of the arc relief channel 300.

[0102] In the above structure, the first outlet 310b and the pressure relief port 201 of the first channel 310 are also located on the top side of the base 110; along the first direction, the second outlet 320b of the second channel 320 is farther away from the base 110 than the first outlet 310b of the first channel 310, and the second outlet 320b of the second channel 320 is farther away from the base 110 than the pressure relief port 201.

[0103] Specifically, along the first direction, the second outlet 320b of the second channel 320 is farther away from the base 110 than the first outlet 310b of the first channel 310. This can be understood as: the distance between the second outlet 320b of the second channel 320 and the base 110 in the first direction is greater than the distance between the first outlet 310b of the first channel 310 and the base 110 in the first direction; along the first direction, the second outlet 320b of the second channel 320 is farther away from the base 110 than the pressure relief port 201. This can be understood as: the distance between the second outlet 320b of the second channel 320 and the base 110 in the first direction is greater than the distance between the pressure relief port 201 and the base 110 in the first direction.

[0104] In the above structure, the second channel 320 allows the arc venting channel 300 to be partially freed from the constraints of the base 110, and the position of the channel outlet 300b can be adjusted according to actual needs, improving the flexibility of the channel outlet 300b layout. Furthermore, the second channel 320 can guide the arc and pressure as far away from the base 110 as possible in the first direction, away from the operator's work area, thus improving safety. For example, the second outlet 320b of the second channel 320 can be located near the ventilation port in the second chamber 102, facilitating the direct discharge of the arc and pressure to the outside through the ventilation port. This is applicable to scenarios where the switchgear 200 is an indoor switchgear 200a. Of course, it is also applicable to scenarios where the switchgear 200 is an outdoor switchgear 200b.

[0105] The second channel 320 described above can be prepared using a pipe or formed by other means. The embodiments of this application do not limit the shape of the first channel 310 and the second channel 320.

[0106] In this embodiment of the application, at least one of the second side plate 204b, the third side plate 204c, and the fourth side plate 204d of the switch cabinet 200 faces the second channel 320.

[0107] For example, as shown in Figures 5 and 6, the second side plate 204b and the fourth side plate 204d both face the second channel 320; as shown in Figure 7, the fourth side plate 204d faces the second channel 320; and as shown in Figure 8, the third side plate 204c faces the second channel 320.

[0108] The above structure allows for flexible adjustment of the position of the second channel 320 based on factors such as the layout direction of the switchgear 200 and the location of the pressure relief port 201, thus improving the flexibility of the structural design. This approach is applicable to scenarios where the switchgear 200 is an indoor switchgear 200a. Of course, it is also applicable to scenarios where the switchgear 200 is an outdoor switchgear 200b.

[0109] In this embodiment of the application, as shown in Figures 9 and 10, the arc-venting channel 300 can also be disposed within the cabinet of the switchgear 200. In this case, it is applicable to scenarios where the switchgear 200 is an outdoor switchgear 200b. Of course, it is also applicable to scenarios where the switchgear 200 is an indoor switchgear 200a.

[0110] Switchgear 200 is an outdoor switchgear 200b, which can be directly installed outdoors. The arc-venting zone 500 can be part of the external environment, directly guiding the electric arc and pressure to the outside environment through the arc-venting channel 300. Of course, the arc-venting zone 500 can also be connected to the external environment, and is not limited to the above description.

[0111] In the case where the arc venting channel 300 can also be installed in the cabinet of the switchgear 200, in order to facilitate arc venting, as shown in Figure 9, the pressure relief port 201 is located on one side of the switchgear 200 in the second direction; as shown in Figures 9 and 10, in the second direction, the channel outlet 300b of the arc venting channel 300 is located on one side of the switchgear 200. For example, the pressure relief port 201 is installed on the cabinet side panel 204 of the switchgear 200; both the channel outlet 300b and the pressure relief port 201 are located on one side of the switchgear 200 in the second direction.

[0112] In practice, the pressure relief port 201 can also be located on the side of the switchgear 200 facing the third direction, and the channel outlet 300b of the arc extinguishing channel 300 can also be located on the side of the switchgear 200 facing the third direction; or, the pressure relief port 201 can also be located on the side of the switchgear 200 facing the third direction and on the side of the switchgear 200 in the second direction, and the channel outlet 300b of the arc extinguishing channel 300 can also be located on the side of the switchgear 200 facing the third direction and on the side of the switchgear 200 in the second direction.

[0113] It should be noted that the pressure relief port 201 is located on the cabinet of the switchgear 200, and the pressure relief port 201 can be directly or indirectly connected to the channel inlet 300a of the arc extinguishing channel 300. The arc extinguishing channel 300 can be located on the base 110 or the cabinet of the switchgear 200. When the arc extinguishing channel 300 is located on the cabinet of the switchgear 200, the pressure relief port 201 and the arc extinguishing channel 300 can be located on the same cabinet side panel 204; or a portion of the arc extinguishing channel 300 and the pressure relief port 201 can be located on the same cabinet side panel 204. For example, both the pressure relief port 201 and the arc extinguishing channel 300 are located on the second side panel 204b.

[0114] In the above structure, the arc venting channel 300 can extend along the first direction. Of course, the arc venting channel 300 can also first extend along the second or third direction to the arc venting area 500, and then extend along the first direction to the top side of the base 110 to achieve safe arc venting; or, the arc venting channel 300 can also extend along a direction that forms an angle with the first direction.

[0115] As shown in Figures 1 and 2, in some embodiments, the housing 100 is provided with a first chamber 101 and a second chamber 102; the switch cabinet 200 is disposed in the first chamber 101, and the arc-venting zone 500 is located in the second chamber 102. Specifically, the switch cabinet 200 is an indoor switch cabinet 200a, which is disposed in the first chamber 101. The first chamber 101 provides the necessary enclosed space for the indoor switch cabinet 200a, thereby ensuring the normal operation and service life of the indoor switch cabinet 200a.

[0116] For example, switchgear 200 is a ring main unit, and the first chamber 101 can be a ring main unit room, which can be a sealed indoor room. The electric arc and pressure of switchgear 200 in the first chamber 101 during pressure relief can be directly guided to the arc relief zone 500 for safe relief through the arc relief channel 300 arranged on the base 110.

[0117] Compared to the first chamber 101, the second chamber 102 can be a chamber with relatively low requirements for sealing, and it can be directly or indirectly connected to the external environment, thereby facilitating the pressure relief of the arc venting zone 500 to the outside.

[0118] It should be noted that the second chamber 102 can be an empty chamber or a chamber containing devices. When devices are placed inside the second chamber 102, the channel outlet 300b of the arc extinguishing channel 300 is positioned away from the devices inside the second chamber 102 to improve the safety of arc extinguishing.

[0119] A portion of the arc-venting channel 300 may be located within the second chamber 102. For example, as shown in Figures 7 and 8, the second channel 320 may be disposed within the second chamber 102 to save internal space in the first chamber 101.

[0120] The second channel 320 can be directly suspended within the second chamber 102. Alternatively, as shown in Figures 7 and 8, the first chamber 101 and the second chamber 102 are separated by a partition 103, and the second channel 320 can be mounted on the partition 103. The second channel 320 can be fixed to the partition 103 using clamps, screws, or other connecting components. Alternatively, the second channel 320 can be integrated directly with the partition 103. In practice, the second channel 320 can be flexibly arranged according to actual needs.

[0121] In this embodiment of the application, as shown in FIG1, the container 100 can be a shipping container 100a. When the container 100 is a shipping container 100a, the shipping container 100a includes a base 110, and the shipping container 100a may further include a panel 120 connected to the base 110. The panel 120 and the base 110 can form the first chamber 101 and the second chamber 102 mentioned above. In this case, the switch cabinet 200 can be an indoor switch cabinet 200a or an outdoor switch cabinet 200b.

[0122] It should be noted that Figures 2-7 also show that the container 100 is a container 100a.

[0123] In this embodiment of the application, as shown in FIG9, when the container 100 is a shipping container 100a, the shipping container 100a may further include a frame 130 connected to the base 110. The frame 130 and the base 110 may form the first chamber 101 and the second chamber 102 mentioned above. In this case, the switch cabinet 200 may be an outdoor switch cabinet 200b. Of course, the switch cabinet 200 may also be an indoor switch cabinet 200a. Components may be added to the first chamber 101 to ensure that the protection requirements of the first chamber 101 meet the usage requirements of the indoor switch cabinet 200a.

[0124] In this embodiment of the application, as shown in FIG11, the container 100 can also be a container plate 100b. When the container 100 is a container plate 100b, the container plate 100b includes a base 110, which is exemplarily the base 110. In this case, the switch cabinet 200 can be an outdoor switch cabinet 200b, which may not have the first chamber 101 and the second chamber 102 provided; the switch cabinet 200 can also be an indoor switch cabinet 200a, which requires the first chamber 101 to be provided on the base 110, or requires the first chamber 101 and the second chamber 102 to be provided on the base 110.

[0125] The technical features mentioned above, as well as those shown individually in the accompanying drawings, can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are those explicitly described herein.

[0126] The above description of the disclosed embodiments enables those skilled in the art to make or use this application.
