Description

Technical Field

[0001] The invention relates to the field of cabinet-type housing installation, and in particular to a cabinet combining method for side expansion gas cabinets. Background Art

[0002] Inflatable cabinets have the characteristics of simple operation, fully enclosed, maintenance-free, and long life, and have been widely used in power systems. In actual applications, it is sometimes necessary to expand the on-site cabinet, and the on-site cabinet cannot be moved. At this time, it is necessary to use an expansion cabinet to connect the on-site cabinet. When connecting the cabinets, side expansion bushings need to be installed on the two cabinets, and the side expansion busbar connector needs to be installed in the side expansion bushings of the two cabinets to achieve electrical connection between the two cabinets. In actual applications, the models, positions, and types of the side expansion bushings of the inflatable cabinets produced by various inflatable cabinet manufacturers are not uniform, so it is difficult to connect the cabinets, and it is difficult to ensure that the side expansion bushings of the two cabinets are accurately aligned. If the matching is not accurate, the interface insulation between the side expansion bushing and the side expansion busbar connector will be destroyed, resulting in insulation discharge problems and even burning of the equipment.

[0003] In order to realize the connection of two cabinets in the prior art, extensive connection method or "side expansion bushing cable connection + transition cabinet" method is often used. The extensive connection method is unreliable. When connecting the cabinets, the side expansion bus connector may damage the interface insulation between the side expansion bushing and the bus connector. The "side expansion bushing cable connection + transition cabinet" method requires the installation of a transition cabinet and cables between the cabinets, which increases the cost of connecting the cabinets. Therefore, when connecting the cabinets, especially for different side expansion inflatable cabinets, how to more accurately ensure the alignment of the side expansion bushing and the side expansion bus connector is particularly important for the quality of the connection. Summary of the invention

[0004] The object of the present invention is to provide a method for combining side expansion gas cabinets to solve the problem that it is difficult to combine cabinets using the existing cabinet combining method and it is difficult to ensure the accurate centering of the busbar side expansion sleeves of the two cabinets.

[0005] In order to solve the above technical problems, the method for combining side expansion gas cabinets of the present invention comprises the following steps:

[0006] 1) Determine the position of the expansion sleeve installation hole on the upper side of the expansion cabinet and the position of the cabinet connection hole according to the position data of the expansion sleeve on the upper side of the on-site cabinet and the position data of the cabinet connection hole;

[0007] 2) According to the determined positions of the side expansion sleeve installation holes on the expansion cabinet and the positions of the cabinet connection holes, the side expansion sleeve installation holes and cabinet connection holes are processed on the expansion cabinet, and the size of the cabinet connection holes on the expansion cabinet is larger than the size of the cabinet connection holes on the on-site cabinet;

[0008] 3) A guide positioning structure is provided on the expansion cabinet, and a guide matching structure matching with the guide positioning structure is installed on the on-site cabinet according to the position data of the side expansion sleeve installation hole on the expansion cabinet and the position data of the guide positioning structure;

[0009] 4) Install the side expansion bushing on the extension cabinet, install the side expansion busbar connector on the side expansion bushing of any cabinet, and then connect the cabinets by positioning and coordinating the guide positioning structure and the guide matching structure.

[0010] Furthermore, when a guide matching structure is set on the field cabinet, the position of the guide matching structure is determined with the aid of an intermediate positioning piece. The intermediate positioning piece has a sleeve reference structure aligned with the side expansion sleeve mounting hole on the extension cabinet and a positioning reference structure aligned with the guide positioning structure. The sleeve reference structure of the intermediate positioning piece is aligned with the side expansion sleeve on the field cabinet, and then the position of the guide matching structure is determined based on the positioning reference structure.

[0011] Furthermore, the intermediate positioning member is a positioning plate, and the casing reference structure is a casing reference hole whose size matches that of the side expansion casing.

[0012] Furthermore, the guide matching structure is a guide pin, the guide positioning structure is a guide hole, and the positioning reference structure is a positioning reference hole for the guide pin to pass through.

[0013] Furthermore, the guide pin is arranged on a connecting plate. When determining the position of the guide matching structure on the field cabinet, the guide pin is first passed through the positioning reference hole, and then the positioning plate is fixed to the field cabinet and the connecting plate is placed between the positioning plate and the side wall of the field cabinet, and then the connecting plate is fixed to the field cabinet.

[0014] Furthermore, fixing holes corresponding to the plug mounting holes on the outside of the side expansion sleeve are provided around the casing reference hole, and the positioning plate is fixed to the field cabinet through the fixing holes.

[0015] Furthermore, the connection plate is provided with connection holes so as to fix it to the cabinet connecting holes of the field cabinet, and the positioning plate is provided with avoidance holes corresponding to the connection holes to avoid the connectors fixing the connection plate to the field cabinet.

[0016] Furthermore, the size of the connection hole is larger than the size of the cabinet connecting hole on the on-site cabinet.

[0017] Furthermore, the connecting piece is a double-headed screw and is used to realize the parallel connection between the on-site cabinet and the expansion cabinet.

[0018] Furthermore, before installing the positioning plate, a pad is installed on the on-site cabinet, and the thickness of the pad is consistent with the thickness of the connecting plate.

[0019] The present invention proposes a brand-new technical solution: the position of the side expansion sleeve of the extension cabinet and the position of the cabinet combining hole are set according to the position data of the side expansion sleeve of the on-site cabinet and the position data of the cabinet combining hole, so that the model and position of the side expansion sleeve of the two cabinets are unified, which provides a prerequisite for the centering of the side expansion sleeve when the two cabinets are combined. At the same time, the size of the cabinet combining hole on the extension cabinet is larger than the size of the cabinet combining hole on the on-site cabinet, so that the installation of the two cabinets can be achieved when there is a slight error in the data of the two cabinets. Then, a guide component with the position of the side expansion sleeve as a reference, one-to-one corresponding and guide matching is installed on the two cabinets. The positioning and matching of the guide component with the position data of the side expansion sleeve as a reference realizes the centering of the side expansion sleeve when the two cabinets are combined, thereby improving the accuracy of the cabinet combination.

[0029] The present invention proposes a new technical solution to the problems existing in the above technical solutions. The core concept of the present invention is: according to the position data of the side expansion sleeve on the on-site cabinet and the position data of the cabinet connecting hole, the position of the side expansion sleeve on the extension cabinet and the position of the cabinet connecting hole are determined, so that the model and position of the side expansion sleeve of the two cabinets are unified, which provides a prerequisite for the centering of the side expansion sleeve when the two cabinets are connected, and also makes the cabinet connecting holes of the two cabinets correspond one to one. Then, a guide component with the position of the side expansion sleeve as a reference, one-to-one corresponding and guideable matching is installed on the two cabinets. The positioning and matching of the guide component with the position data of the side expansion sleeve as a reference realizes the centering of the side expansion sleeve when the two cabinets are connected, thereby improving the accuracy of the cabinet connection.

[0030] In view of the above technical problems, a method for combining side expansion gas cabinets of the present invention comprises the following steps:

[0031] 1) Determine the location of the expansion sleeve installation hole on the upper side of the expansion cabinet 2 and the location of the cabinet connection hole based on the location data of the expansion sleeve on the upper side of the on-site cabinet 1 and the location data of the cabinet connection hole. Figure 1 As shown, the position data of the side expansion sleeve of group I on the field cabinet 1 needs to be measured (including Figure 1 The distance A1 between the side expansion sleeves shown, and the distance A2 from the center of the side expansion sleeve to the side wall of the cabinet) are shown. In this way, the model and position of the side expansion sleeves of the two cabinets can be unified, which provides a prerequisite for the centering of the side expansion sleeves when the two cabinets are combined. At the same time, the position of the cabinet combination holes on the extension cabinet 2 is determined according to the II group of cabinet combination holes on the field cabinet 1, which provides a prerequisite for the combination of the two cabinets. In addition, in other embodiments, when there are also III groups of cabinet combination holes around the side expansion sleeves of the field cabinet 1, corresponding cabinet combination holes can be set on the extension cabinet 2 according to the positions of the III groups of cabinet combination holes on the field cabinet. 2) According to the determined positions of the side expansion sleeve installation holes on the extension cabinet 2 and the positions of the cabinet combination holes, the side expansion sleeve installation holes and the cabinet combination holes are processed on the extension cabinet 2. The cabinet combination holes on the extension cabinet 2 in this embodiment are set on the positioning blocks, and the size of the cabinet combination holes on the extension cabinet 2 is larger than the size of the cabinet combination holes on the field cabinet. In this way, the installation of the two cabinets can still be achieved when there is a slight error in the data of the two cabinets. 3) A guide positioning structure is provided on the expansion cabinet 2, and a guide matching structure that matches the guide positioning structure is installed on the field cabinet 1 according to the position data of the side expansion sleeve of the expansion cabinet 2 and the position data of the guide positioning structure. 4) The side expansion sleeve is installed on the expansion cabinet, and the side expansion busbar connector 9 is installed on the side expansion sleeve of any cabinet, and then the cabinets are combined through the positioning and matching of the guide positioning structure and the guide matching structure. In this way, the model and position of the side expansion sleeve on the cabinet are unified. At the same time, the positioning and matching of the guide component based on the position data of the side expansion sleeve realizes the centering of the side expansion sleeve when the two cabinets are combined, thereby improving the accuracy of the cabinet combination.

[0032] In this embodiment, if Figure 3 , Figure 4 As shown, when the guide matching structure is provided on the field cabinet 1, the position of the guide matching structure is determined with the aid of an intermediate positioning member. The intermediate positioning member has a sleeve reference structure aligned with the side expansion sleeve installation hole on the extension cabinet and a positioning reference structure aligned with the guide positioning structure. The sleeve reference structure of the intermediate positioning member is aligned with the side expansion sleeve on the field cabinet 1, and then the position of the guide matching structure is determined based on the positioning reference structure. The intermediate positioning member also ensures that the guide matching structure will not deviate during installation through the sleeve reference structure and the positioning reference structure thereon, so that the guide matching structure installed on the field cabinet 1 is aligned with the guide positioning structure, and its existence makes the installation of the guide matching structure easier. In addition, in other embodiments, the position data of the guide positioning structure and the side expansion sleeve can be measured, and the guide matching structure can be directly installed on the field cabinet through the position data of both.

[0033] In this embodiment, the intermediate positioning member is a positioning plate 4, and the casing reference structure is as follows: Figure 6 The size of the sleeve reference hole 13 shown matches the port of the side expansion sleeve mounting hole. The sleeve reference hole 13 has a simple structure and is easy to manufacture. The sleeve reference hole 13 can be used to quickly and accurately place the positioning plate 4 in the correct position of the field cabinet 1. In addition, in other embodiments, the sleeve reference structure can also be a positioning protrusion on the positioning plate 4 that is adapted to the side expansion sleeve. The positioning plate 4 in this embodiment is a right-angle plate, which saves space and can avoid interference with other components on the cabinet due to its large size. Of course, in other embodiments, the intermediate positioning member can also be a positioning frame, which includes a sleeve reference ring that is consistent with the port of the side expansion sleeve mounting hole, and also includes a positioning member reference ring that can be fitted with a guide matching structure. The distance between the sleeve reference ring and the positioning member reference ring is set according to the distance between the side expansion sleeve and the guide positioning structure and is connected by a steel plate.

[0034] In this embodiment, the guide matching structure is a guide pin 10, the guide positioning structure is a guide hole, and the positioning reference structure is a hole for the guide pin 10 to pass through. Figure 5 The positioning reference hole 12 is shown. Figure 8 As shown, the guide positioning structure is a guide hole on the guide block 7. The guide hole and the guide pin 10 have a simple structure and can achieve the guide matching of the two cabinets. The positioning reference hole 12 set on the positioning plate 4 can accurately position the guide pin 10. Of course, in other embodiments, the guide matching structure can be a guide hole, and the guide positioning structure can be a guide pin.

[0035] In this embodiment, the guide pin 10 is arranged on a connecting plate 6. Figure 6 , Figure 7As shown, the guide pins 10 are arranged at intervals along the length direction of the connecting plate 6. When determining the position of the guide matching structure on the field cabinet 1, first pass the guide pin 10 through the positioning reference hole 12, then fix the positioning plate 6 on the field cabinet 1 and make the connecting plate 6 between the positioning plate 4 and the side wall of the field cabinet 1, and then fix the connecting plate 6 on the field cabinet 1. In this way, the alignment of the guide pin 6 and the guide hole is completed by only installing the connecting plate 6 on the field cabinet 1, which is simple to operate and convenient to install. Of course, in other embodiments, the guide pin can also be set separately, and a mounting plate extending radially outward is set at the end of the guide pin, and the guide pin is fixed to the field cabinet through the mounting plate.

[0036] In this embodiment, fixing holes corresponding to the plug mounting holes on the outside of the side expansion sleeve are provided around the casing reference hole 13, and the positioning plate 4 is fixed to the field cabinet through the fixing holes. In order to install the side expansion sleeve, six mounting holes are usually provided around the side expansion sleeve mounting hole, three of which are side expansion sleeve mounting holes, and the other three are plug mounting holes. The side expansion sleeve is provided on the side expansion sleeve aluminum plate 8, and the side expansion sleeve aluminum plate 8 is installed on the cabinet through three side expansion sleeve connection holes, and the remaining three plug mounting holes are vacant. The positioning plate 4 uses the fixing holes thereon and the three vacant plug mounting holes to install the positioning plate 4 on the field cabinet 1, which further ensures the precise positioning of the positioning plate and also efficiently utilizes the original plug mounting holes of the cabinet.

[0037] In this embodiment, the connecting plate 6 is provided with Figure 2 The connection holes 14 shown are for fixing it at the cabinet-joining holes of the field cabinet 1, and the position corresponding to the connection holes 14 is provided with avoidance holes 11 on the positioning plate 4 to avoid the connectors that fix the connection plate 4 to the field cabinet. The II group cabinet-joining holes on the field cabinet correspond to the connection holes 14, and during installation, the connectors are passed through the connection holes 14 and the II group cabinet-joining holes to realize the connection between the connection plate 6 and the field cabinet. The avoidance holes 11 provided on the positioning plate 4 can avoid the connectors, so that the positioning plate 4 can be removed after the connection plate 6 is installed.

[0038] In this embodiment, the size of the connection hole 14 is larger than the size of the cabinet connection hole on the on-site cabinet. At this time, the connection hole replaces the original cabinet connection hole, and correspondingly, the cabinet connection hole on the expansion cabinet 2 is set on the positioning block, and the size of the cabinet connection hole on the expansion cabinet 2 is also larger than the cabinet connection hole on the on-site cabinet; in this way, a certain error can be allowed when the two cabinets are installed, avoiding the difficulty in installing the guide matching structure due to the error that makes the cabinet connection hole unable to be aligned.

[0039] In this embodiment, the connecting member is as follows Figure 5 The double-headed screw rod 5 is shown and is used to realize the cabinet connection between the field cabinet 1 and the expansion cabinet 2. In this way, the two ends of the double-headed screw rod 5 can respectively pass through the guide blocks and the connecting plates of the two cabinets to realize the connection of the two cabinets.

[0040] In this embodiment, before installing the positioning plate 4, a Figure 5 , Figure 6 The pad 3 shown is provided, and the thickness of the pad 3 is consistent with the thickness of the connecting plate 6. The pad of this embodiment is a composite pad composed of multiple thin plates. If there is no pad 3, when the connecting plate 6 and the positioning plate 4 are installed on the field cabinet, because the connecting plate 6 has a certain thickness, there is also a certain distance between the connecting plate 6 and the field cabinet. In this way, when the positioning plate 4 is positioned using the sleeve reference hole 13, there may be a certain error. Therefore, in this embodiment, a pad 3 with the same thickness as the connecting plate 6 is provided, and a sleeve avoidance hole consistent with the port of the side expansion sleeve installation hole is provided on the pad 3. In this way, after the pad 3 is installed on the corresponding cabinet, the positioning plate 4 is expanded and installed on the pad 3. The sleeve avoidance hole on the pad 3 can be used as an auxiliary part to ensure that the sleeve reference hole 13 on the positioning plate 4 is aligned with the position of the side expansion sleeve, thereby ensuring the accuracy of the position of the positioning plate.
