[0042] Embodiment 1

[0043] Please refer to Figure 1-Figure 6 As shown, this embodiment provides a support frame for a vacuum circuit breaker, comprising:

[0044] The first mounting plate 10 is arranged at one end of the isolating switch 20 of the vacuum circuit breaker 2. One end of the vacuum circuit breaker 2 is connected to the switch cabinet through the first mounting plate 10. In addition, the plate surface of the first mounting plate 10 and the end surface of the isolating switch 20 are connected by multiple bolts, which can enhance the firmness of the connection between the first mounting plate 10 and the isolating switch 20, further ensure the stability of the first mounting plate 10 in connecting the vacuum circuit breaker 2 to the switch cabinet, and the bolt locking connection is also convenient for disassembly and assembly.

[0045] The second mounting plate 11 is arranged on the other end of the vacuum circuit breaker 2, and the other end of the vacuum circuit breaker 2 is connected to the switch cabinet through the second mounting plate 11, that is, the vacuum circuit breaker 2 is arranged between the first mounting plate 10 and the second mounting plate 11, and the plate surface of the second mounting plate 11 and the other end surface of the vacuum circuit breaker 2 are locked and connected by multiple bolts.

[0046] In this way, both ends of the vacuum circuit breaker 2 can be connected to the switch cabinet through the first mounting plate 10 and the second mounting plate 11. The connection at both ends is more secure than the connection at one end. The weight of the vacuum circuit breaker 2 is jointly supported by the two connection points at both ends, and the force is more balanced. The connection between the vacuum circuit breaker 2 and the switch cabinet is not easy to loosen, which can ensure the stability of the vacuum circuit breaker 2 and the safety of use.

[0047] and a support frame 12, one end of which is arranged on the second mounting plate 11, and the other end is close to the first mounting plate 10, the support frame 12 is provided with at least one first support beam 121 on the isolating switch 20, for supporting the weight of the isolating switch 20, and / or, the support frame 12 is provided with at least one second support beam 122 on the vacuum switch 21 of the vacuum circuit breaker 2, for supporting the weight of the vacuum switch 21. It should be noted that, since the isolating switch 20 and the vacuum switch 21 are connected, when only the first support beam 121 or the second support beam 122 is provided, the first support beam 121 or the second support beam 122 can support the weight of the isolating switch 20 and the vacuum switch 21 as a whole. In addition, a plurality of the first support beams 121 and the second support beams 122 can be provided along the length direction of the isolating switch 20 and the vacuum switch 21, respectively, to increase the support strength and make the force more balanced.

[0048] Furthermore, on the basis of setting the first mounting plate 10 and the second mounting plate 11 as two connection points to support the vacuum circuit breaker 2, a support frame 12 is set between the first mounting plate 10 and the second mounting plate 11 to support the weight of the middle part of the vacuum circuit breaker 2, that is, to support the weight of the disconnector 20 and the vacuum switch 21, to play a role in coordinating the overall supporting strength, so that the support frame 1 is evenly stressed as a whole, thereby achieving an effect of overall balanced and stable stress.

[0049] like Figure 1 and Figure 3 As shown, in this embodiment, a plurality of locking holes 101 are evenly spaced around the first mounting plate 10 and the second mounting plate 11. The first mounting plate 10 and the second mounting plate 11 can be connected to the switch cabinet by bolts through the locking holes 101, so that the vacuum circuit breaker 2 is sealed in the switch cabinet.

[0050] like Figure 1 and Figure 3 As shown, in this embodiment, a plurality of lifting rings 102 are provided on the first mounting plate 10. Since the vacuum circuit breaker 2 is heavy, in order to facilitate the installation of the vacuum circuit breaker 2 in the switch cabinet, the support frame 1 can be assembled first, and one end of the vacuum circuit breaker 2 can be lifted by using the lifting ring 102 to stabilize the installation position of the vacuum circuit breaker 2, so as to facilitate the installation of the vacuum circuit breaker 2 in the switch cabinet.

[0051] like Figure 1 and Figure 3As shown, in this embodiment, the second mounting plate 11 includes a first frame plate 111 and a second frame plate 112, and the first frame plate 111 and the second frame plate 112 are bolt-locked or detachably connected. For ease of understanding, it should be noted here that the vacuum circuit breaker 2 has a split design, that is, the disconnector 20 and the vacuum switch 21 can be disassembled. When the support frame 1 is used to assemble the split vacuum circuit breaker 2, in order to facilitate disassembly, the second mounting plate 11 is also designed to be split, wherein the first frame plate 111 is connected to one end of the disconnector 20, and the second frame plate 112 is connected to one end of the vacuum switch 21. The connection between the first frame plate 111 and the second frame plate 112 is locked by bolts for easy disassembly, so that the vacuum circuit breaker 2 can be disassembled into two parts for installation, making the installation more convenient.

[0052] like Figure 1 and Figure 3 As shown, in this embodiment, the support frame 12 is composed of a front vertical frame 123 and two side vertical frames 124 connected to each other vertically. The front vertical frame 123 is provided with a through hole 1231 for supporting the end of the vacuum switch 21 close to the first mounting plate 10.

[0053] Specifically, after a front vertical frame 123 and two side vertical frames 124 are connected vertically to each other to form a support frame 12, the support frame 12 is connected to the second mounting plate 11 to form a closed square frame to ensure that the structure of the support frame 12 is stable and can support the weight of the disconnector 20 and the vacuum switch 21 located in the middle of the vacuum circuit breaker 2. Among them, the vacuum switch 21 is located in the support frame 12 and supported by the second support beam 122. Since the vacuum switch 21 is located below the disconnector 20, it also bears the weight of the disconnector 20 to a certain extent. Since the front vertical frame 123 is arranged close to the first mounting plate 10, a through hole 1231 is arranged on the front vertical frame 123. On the one hand, the through hole 1231 can allow the vacuum switch 21 to pass through. On the other hand, the through hole 1231 can also support the end of the vacuum switch 21 close to the first mounting plate 10, further improving the support strength and balanced stability of the support frame 1.

[0054] like Figure 1 and Figure 3As shown, in this embodiment, the front vertical frame 123, the side vertical frame 124, the first support beam 121, the second support beam 122 and the second mounting plate 11 are connected by bolts or disassembly. In this way, the support frame 12 and the second mounting plate 11 can be flexibly disassembled and assembled, and the various components constituting the support frame 12 can also be disassembled and assembled, so as to facilitate the installation and maintenance of the vacuum circuit breaker 2. The various components are assembled in sequence, making the assembly of the support frame 1 and the vacuum circuit breaker 2 more convenient. When the vacuum circuit breaker 2 needs to be repaired, it is not necessary to disassemble the support frame 1 as a whole, and when the components of the support frame 1 are damaged, it is not necessary to replace the support frame 1 as a whole. Only the damaged components need to be replaced, saving the maintenance cost.

[0055] like Figure 1 and Figure 3 As shown, in this embodiment, mounting holes 1241 are disposed opposite to each other on the two side vertical frames 124 , and the second support beam 122 is disposed on the mounting holes 1241 .

[0056] Specifically, after the support frame 1 and the vacuum circuit breaker 2 are assembled, the vacuum switch 21 of the vacuum circuit breaker 2 is located in the support frame 12 of the support frame 1 and supported by the second support beam 122. The two ends of the second support beam 122 are respectively connected to the two side vertical frames 124 of the support frame 12. In this embodiment, mounting holes 1241 are opened at the relative positions of the two side vertical frames 124, and the two ends of the second support beam 122 are mounted on the two mounting holes 1241, and are locked and connected with the mounting holes 1241 by bolts to increase the support strength and stability of the second support beam 122. In addition, the mounting hole 1241 can be a strip-shaped long hole, so that when multiple second support beams 122 are provided, the multiple second support beams 122 can be mounted one by one along the length direction of the mounting hole 1241 and connected to the mounting hole 1241.

[0059] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, a plurality of connecting holes 1211 are provided on the first supporting beam 121 and the second supporting beam 122 of the supporting frame 1, and a locking protrusion 201 is provided on the isolating switch 20 and the vacuum switch 21 of the vacuum circuit breaker 2, and the top of the locking protrusion 201 is an arc-shaped structure, and is integrally formed with the isolating switch 20 and the vacuum switch 21, and a bolt locking connection is provided between the locking protrusion 201 and the connecting hole 1211, and the vacuum circuit breaker 2 and the supporting frame 1 can be assembled or disassembled by disassembling the connection between the locking protrusion 201 and the first supporting beam 121 and the second supporting beam 122; or a welding connection is provided, and this connection method can be disassembled or assembled on the supporting frame 1 by disassembling the connection between the first supporting beam 121 and the second supporting beam 122 and the supporting frame 12.
