Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to an expandable standard switch cabinet. Background Art

[0002] The primary function of switchgear is to open and close, control, and protect electrical equipment during power generation, transmission, distribution, and conversion in power systems. The components within a switchgear primarily include circuit breakers, disconnectors, load switches, operating mechanisms, transformers, and various protective devices. Switchgear can be categorized in many ways. For example, they can be divided into removable and fixed types based on circuit breaker mounting methods; they can also be divided into open, metal-enclosed, and metal-clad types based on their structure; and they can be further categorized by voltage level, including high-voltage, medium-voltage, and low-voltage types.

[0003] The switch cabinets in the prior art have different structures and are usually used in sets. When it is necessary to add or reduce cabinets, the entire set of cabinets can only be replaced, which has poor versatility. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides an expandable standard switch cabinet, which solves the technical problem of poor flexibility in the use of the switch cabinet in the prior art.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0006] An expandable standard switchgear cabinet, comprising a first box and a busbar box, wherein the busbar box is provided with a plurality of busbar holes connected to the first box and for passing busbars, characterized in that: a hinged rod is further provided at the relative connection between the first box and the busbar box, the hinged rod being vertically arranged and slidably connected to the first box and the busbar box, the hinged rod being connected to a movable baffle and a side baffle, and an elastic component for driving the hinged rod to slide vertically is further provided between the hinged rod and the first box and the busbar box;

[0007] The elastic component includes a folding arm 1 and a folding arm 2 that are hinged to each other. The folding arm 1 is hinged to a hinged rod, and the folding arm 2 is hinged to the box body 1 and the busbar box. An elastic device for driving the folding arm 1 and the folding arm 2 to unfold is provided between the folding arm 1 and the folding arm 2.

[0008] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that: the elastic device is a torsion spring, the torsion spring is sleeved on the hinge shaft of folding arm one and folding arm two, and the two power output ends of the torsion spring are respectively connected to folding arm one and folding arm two.

[0009] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that: hinge holes are provided at both ends of the movable baffle, and when the movable baffle is connected to the box body, the hinge rod passes through the hinge hole.

[0010] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that two hinge holes are provided at both ends of the side baffles, and when the side baffles are connected to the box body 1 and the busbar box, the hinge holes 2 are connected to the hinge rods.

[0011] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that the inner walls of the box body 1 and the busbar box are connected to the hinge rod through a guide block, and the guide block is detachably connected to the box body 1 and the busbar box.

[0012] As an optimized solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that the folding arm 1 is connected to the hinge rod through a hinge plate.

[0013] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that the hinged rod is hinged to the hinged rod via a connecting block, and the hinged rod is fixedly connected to the connecting block.

[0014] As an optimization solution of the present invention, the aforementioned expandable standard switch cabinet is characterized in that the side of the side baffle is further provided with a flange.

[0015] The beneficial effects achieved by the present invention are:

[0016] Compared to existing technologies, this invention allows for the expansion of the switchgear by creating an extended enclosure with multiple side panels placed side by side between the first enclosure and the busbar box, enhancing the overall scalability of the switchgear. The width of the expansion enclosure is determined by the width of the side panels and can be adjusted based on actual needs. After the switchgear is expanded, if the busbar holes are no longer needed, they can be shielded with movable panels.

[0017] Folding arm 1 and folding arm 2 can be made relatively long and connected by a torsion spring. Therefore, within the working range of the elastic component, the hinged rod can slide up and down a large distance, which is sufficient to allow the side baffle to be inserted into the hinged rod. The present invention also has a movable baffle, which is used to block the busbar hole when the busbar hole is not in use. The installation method of the movable baffle can be referred to as the side baffle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] like Figures 1 to 6 This embodiment discloses an expandable standard switchgear cabinet, comprising a housing 1 and a busbar box 2. The busbar box 2 is provided with a plurality of busbar holes 22, which are connected to the housing 1 and are used to pass busbars. The embodiment is characterized in that a hinged rod 5 is provided at the relative connection between the housing 1 and the busbar box 2. The hinged rod 5 is vertically arranged and slidably connected to the housing 1 and the busbar box 2. The hinged rod 5 is connected to a movable baffle 3 and a side baffle 6. An elastic component 4 is provided between the hinged rod 5 and the housing 1 and the busbar box 2 to drive the hinged rod 5 to slide vertically. A busbar is provided within the busbar box 2, and the busbar is connected to a bridge.

[0027] The elastic component 4 includes a folding arm 1 41 and a folding arm 2 42 that are hinged to each other. The folding arm 1 41 is hinged to the hinge rod 5, and the folding arm 2 42 is hinged to the box body 1 and the busbar box 2. An elastic device is provided between the folding arm 1 41 and the folding arm 2 42 for driving the folding arm 1 41 and the folding arm 2 to unfold.

[0028] Specifically, the elastic device of this embodiment is a torsion spring 43, which is sleeved on the hinge shafts of the folding arm 1 41 and the folding arm 2 42, and the two power output ends of the torsion spring 43 are respectively connected to the folding arm 1 41 and the folding arm 2 42.

[0029] like Figure 4As shown, hinge holes 31 are provided at both ends of the movable baffle 3. When the movable baffle 3 is connected to the box body 1, the hinge rod 5 passes through the hinge hole 31.

[0030] like Figure 5 and Figure 6 As shown, both ends of the side baffle 6 are provided with hinge holes 61. When the side baffle 6 is connected to the box body 1 and the busbar box 2, the hinge holes 61 are connected to the hinge rod 5. When multiple side baffles 6 are stacked for use, the side of the side baffle 6 is also provided with a flange 62. The flange 62 is used to connect to the other side of the side baffle 6 (the side without the flange), thereby strengthening the tightness and connection strength between the side baffles 6.

[0031] The specific structure of the vertical sliding of the hinge rod 5 in this embodiment is as follows: the inner walls of the box body 1 and the busbar box 2 are both connected to the hinge rod 5 via a guide block 52. The guide block 52 is detachably connected (e.g., with screws) to the inner walls of the box body 1 and the busbar box 2, and the hinge rod 5 passes through the guide block 52.

[0032] During the rotation of folding arm 1 41 relative to folding arm 2 42 , folding arm 2 42 cannot move horizontally. To compensate for horizontal errors, this embodiment further provides a hinge plate between folding arm 1 41 and hinge rod 5 . Specifically, hinge rod 5 is hinged to hinge rod 5 via connecting block 51 , and hinge rod 5 is fixedly connected to connecting block 51 .

[0033] During use, when the entire switch cabinet only requires box body 1 and busbar box 2, the hinged rod 5 and the elastic component 4 are not used, and any connection method in the existing technology can be adopted between box body 1 and busbar box 2, and the hinged rod 5 and the elastic component 4 will not affect the connection between the two.

[0034] When expansion is required, the distance between them is increased to the required length. Side baffles 6 are selected as needed, and some guide blocks 52 are removed (otherwise, this will affect the connection of hinge hole 2 62). Then, hinge rod 5 is pressed downward. Since folding arm 1 41 and folding arm 2 42 can be made relatively long and are connected by torsion spring 43, hinge rod 5 can slide up and down a considerable distance within the operating range of the elastic component, a distance sufficient for side baffle 6 to fit onto hinge rod 5. The side of the switchgear requires multiple side baffles 6 to form a complete structure, so the space at the top of hinge rod 5 only needs to be larger than that of one side baffle 6. When multiple side baffles 6 are connected sequentially from bottom to top, the gaps between them are blocked by flanges 62, which also serve as reinforcement ribs. After installing side baffles 6, guide blocks 52 are also required to ensure the connection strength between hinge rod 5 and box body 1 and busbar box 2.

[0035] When all the side baffles 6 on both sides are completed, an extended box can be formed between the box 1 and the busbar box 2 for installing other electrical components.

[0036] This embodiment further includes a movable baffle 3 , which is used to shield the busbar hole 22 . When the busbar hole 22 is not needed, it can be blocked. The installation method of the movable baffle 3 can refer to the side baffle 6 .

[0037] Compared to existing technologies, this embodiment utilizes multiple side panels 6 placed side by side between the cabinet 1 and the busbar box 2 to form an extended cabinet, enhancing the scalability of the entire switchgear. The width of the extended cabinet is determined by the width of the side panels 6 and can be selected based on actual needs. After the switchgear is expanded, if the busbar holes 22 are no longer needed, they can be shielded with movable panels 3.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
