Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an installation cabinet suitable for two circuit breakers. Background Art

[0002] The incoming cabinet of the MNS cabinet is equipped with a frame circuit breaker with a rated current ranging from 630A to 6300A, which is configured according to project requirements. The weight of the small current circuit breaker is relatively light, and there is no special requirement for the strength of the mounting plate. When the rated current reaches 5000 or 6300A, not only the cabinet frame needs to be reinforced, but also the mounting plate.

[0003] The common reinforcement solution is to add two U-shaped reinforcement ribs on the back of the mounting plate, and use self-tapping screws to connect the mounting plate and the side beam. In addition, four columns are required to support the bottom of the reinforcement ribs, and the bottom support provides some support force to reduce the pressure on the mounting plate.

[0004] However, when two 5000A circuit breakers are installed in one cabinet, they need to be installed up and down, and at this time, it is impossible to install a column under the mounting plate to support the ground. As a result, the circuit breaker mounting plate is easy to break during use. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an installation cabinet suitable for two circuit breakers, which overcomes the shortcomings of the prior art and has a reasonable design. The angle iron frame and the bent edge work together to support the high-current circuit breaker and the corresponding connecting copper bar, thereby effectively ensuring the support stability of the circuit breaker installation plate.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A mounting cabinet suitable for two circuit breakers, comprising a cabinet body, a circuit breaker mounting plate fixedly mounted in the cabinet body, and a high-current circuit breaker mounted on the circuit breaker mounting plate; the characteristic is that: both front and rear sides of the circuit breaker mounting plate are provided with bent edges bent downward, two mutually parallel angle iron frames are fixedly mounted on the bottom of the circuit breaker mounting plate, support columns are installed in the middle of both left and right side surfaces of the cabinet body, and the circuit breaker mounting plate is connected to the support columns.

[0008] Preferably, the height of the bent edge is 75 mm.

[0009] Preferably, the angle iron frame is fixedly welded to the inner side of the bent edge.

[0010] Preferably, the angle iron frame adopts an L-shaped structure.

[0011] Preferably, four support columns are provided, and two of them form a group, and the two groups of support columns are respectively fixedly mounted on the left and right sides of the cabinet.

[0012] Preferably, an angle connecting block is installed at the bottom of the support column.

[0013] Preferably, the angle iron frame and the circuit breaker mounting plate are fixed by welding, and the welding points between the angle iron frame and the circuit breaker mounting plate are sprayed with silver powder paint.

[0014] Preferably, two circuit breaker mounting plates are provided, and the two circuit breaker mounting plates are arranged side by side up and down.

[0015] Preferably, the circuit breaker mounting plate is made of galvanized aluminum plate.

[0016] Preferably, the angle iron frame is made of high-strength structural steel.

[0017] The utility model provides an installation cabinet suitable for two circuit breakers. It has the following beneficial effects: by arranging a downward vertically bent edge on both sides of the front and rear sides of the circuit breaker installation plate, and then by welding and fixing the angle iron frame to the bottom of the circuit breaker installation plate, the high-current circuit breaker and the corresponding connecting copper busbar can be supported by the combined action of the angle iron frame and the bent edge, thereby effectively ensuring the support stability of the circuit breaker installation plate.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0025] Embodiment 1, as Figure 1-3As shown, a mounting cabinet suitable for two circuit breakers includes a cabinet body 1, two circuit breaker mounting plates 2 are fixedly installed in the cabinet body 1, the two circuit breaker mounting plates 2 are arranged side by side up and down, and high-current circuit breakers are installed on the circuit breaker mounting plates 2; the front and rear sides of the circuit breaker mounting plates 2 are both provided with bent edges 4 bent downward, and two mutually parallel angle iron frames 5 are fixedly installed at the bottom of the circuit breaker mounting plates 2. In this embodiment, the circuit breaker mounting plates 2 are made of galvanized aluminum plates, and the angle iron frames 5 are made of an L-shaped angle iron frame structure made of high-strength structural steel.

[0026] Working principle:

[0027] By providing a bent edge 4 that is bent vertically downward on both sides of the front and rear sides of the circuit breaker mounting plate 2, and the bent edge 4 and the circuit breaker mounting plate 2 are designed as an integrated structure, and by welding and fixing the 6# angle iron frame 5 to the bottom of the circuit breaker mounting plate 2, and in this embodiment, the angle iron frame 5 can be fixedly welded to the inner side of the bent edge 4. Thus, the high-current circuit breaker and the corresponding connecting copper bar can be supported by the joint action of the angle iron frame 5 and the bent edge 4. Thus, the supporting stability of the circuit breaker mounting plate 2 is effectively guaranteed.

[0028] Embodiment 2, as a further preferred solution of Embodiment 1, the height of the bending edge 4 can be increased by 25 mm on the basis of the original height of 50 mm, that is, the height of the bending edge 4 is set to 75 mm. This enhances the anti-deformation ability of the bending edge 4 in the vertical direction, thereby further ensuring the support stability of the circuit breaker mounting plate 2.

[0029] Embodiment 3, as a further preferred solution of embodiment 1, two support columns 6 are fixedly installed in the middle of the left and right sides of the cabinet 1, the circuit breaker mounting plate 2 is connected to the support columns 6, and corner connecting blocks 7 are installed at the bottom of the two support columns 6. The corner connecting blocks 7 are used to increase the stability of the connection between the two support columns 6 and the entire cabinet 1. The sides of the circuit breaker mounting plate 2 are connected by the two support columns 6, so that the supporting stability of the circuit breaker mounting plate 2 is further enhanced through the joint action of the cabinet 1, the support columns 6 and the circuit breaker mounting plate 2, and then the strength of the entire installation cabinet is enhanced.

[0030] Embodiment 4, as a further preferred embodiment of embodiment 1, the angle iron frame 5 and the circuit breaker mounting plate 2 are fixed by welding, and the welding points between the angle iron frame 5 and the circuit breaker mounting plate 2 are sprayed with silver powder paint. The stability of the fixation between the angle iron frame 5 and the circuit breaker mounting plate 2 is achieved by full welding, and the silver powder paint is sprayed to avoid the problem of rust at the welding points causing the welding points to be disconnected.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
