[0035] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0036] A prefabricated substation, also known as a box-type substation, is a type of power equipment that integrates high-voltage switchgear, transformers, low-voltage switchgear, and corresponding protection, control, measurement, and auxiliary facilities into a single enclosed enclosure. The product is arranged in a U-shape and is divided into a medium-voltage compartment, a transformer compartment, and a low-voltage compartment.

[0037] The high-voltage switchgear 200 is located in the medium-voltage compartment. In the existing technology, the high-voltage switchgear 200 is fixed by rigid connection of angle steel and two opposing corner plates. During transportation, the fixing structure is in direct contact with the high-voltage switchgear 200. If it is impacted, there is no buffer between the fixing structure and the high-voltage switchgear 200, which can easily cause damage to the high-voltage switchgear 200 in the transformer substation. In addition, for high-voltage switchgear 200 of different brands and models, it is necessary to adjust the height of the angle steel and the distance between the two corner plates. The adjustment steps are complicated. Furthermore, the space inside the high-voltage switchgear 200 is limited, and the corner plates need to be fixed to the angle steel with bolts, making it difficult for workers to perform complex operations in the limited space.

[0038] To address the aforementioned problems, this utility model proposes a fixing structure for a high-voltage switchgear 200 and a prefabricated substation, which solves the problems of existing high-voltage switchgear 200 fixing structures lacking buffering function and having complex installation and adjustment.

[0039] refer to Figure 1 and Figure 2 The present invention relates to a fixing structure for a high-voltage switchgear 200 and the following embodiments thereof:

[0040] The fixing structure for the high-voltage cabinet 200 in this embodiment of the utility model includes a chassis 100, a fixing component 300, a mounting component 400, and a connecting component 500.

[0041] The chassis 100 is provided with at least one installation chamber for housing the high voltage cabinet 200. The installation chamber has an inlet and outlet. The high voltage cabinet 200 is pushed into the installation chamber through the inlet and outlet to complete the installation. The fixing component 300 is located on one side inner wall of the installation chamber and has multiple fixing positions 301. The installation component 400 is located on the high voltage cabinet 200 and has multiple mounting positions 401.

[0042] The connecting assembly 500 includes at least two elastic straps 510, one end of each elastic strap 510 being detachably connected to different mounting positions 401, and the other end being detachably connected to different fixing positions 301, so as to install and fix the high voltage cabinet 200 in the installation room, facilitate stable transportation, and prevent tipping due to bumps.

[0043] Since the connecting component 500 is an elastic strap 510, it provides an elastic connection between the installation chamber and the high-voltage cabinet 200. The elasticity of the elastic strap 510 acts as a buffer, preventing the high-voltage cabinet 200 from colliding with the inner wall of the installation chamber when impacted, thus avoiding damage to the high-voltage cabinet 200. The elastic strap 510 can be detachably connected to different installation positions 401 and fixed positions 301, allowing for flexible adjustment of the position of the elastic strap 510. The length of the elastic strap 510 can also be easily changed by binding, knotting, or tightening the external mechanism to adapt to various high-voltage cabinets 200 of different brands, models, and sizes, making it highly adaptable and flexible.

[0044] Furthermore, regarding the installation positions of the fixing component 300 and the mounting component 400, the high-voltage cabinet 200 is in close contact with the inner wall of the side where the fixing component 300 is located. Multiple mounting positions 401 are located on the side of the high-voltage cabinet 200 away from the fixing component 300, so that at least two elastic straps 510 are connected to both sides of the high-voltage cabinet 200 for tightening and fixing. The elastic straps 510 apply a tensile force towards the inner wall to the high-voltage cabinet 200, which is balanced with the supporting force applied by the inner wall to the high-voltage cabinet 200, so that the high-voltage cabinet 200 is fixed close to the inner wall. Only a minimum of two elastic straps 510 are needed to complete the fixed installation of the high-voltage cabinet 200, which is simple in structure and saves costs.

[0045] In this embodiment of the utility model, since the installation chamber has an inlet and outlet, the high-voltage cabinet 200 is pushed into the installation chamber through the inlet and outlet to complete the installation. It is most convenient to push it into the rear wall that is close to the inlet and outlet. Therefore, the high-voltage cabinet 200 is in close contact with the rear wall of the installation chamber. The fixing component 300 is provided on the rear wall. There are two elastic straps 510. One end of the two elastic straps 510 is connected to different fixing positions 301, and the other end is connected to different installation positions 401 to form a stable fixation of the high-voltage cabinet 200.

[0046] In other utility model embodiments, the number and connection position of the elastic straps 510 can be in other forms, as long as they can achieve force balance of the high voltage cabinet 200 and prevent it from shaking. For example, there are four elastic straps 510, four fixing positions 301 are arranged around the high voltage cabinet 200 at the bottom of the installation chamber, and four installation positions 401 are evenly distributed on the top of the high voltage cabinet 200.

[0047] Furthermore, in this embodiment of the present invention, the two elastic straps 510 are arranged in a cross manner, so that the force exerted by the elastic straps 510 on the high voltage cabinet 200 is cross-direction. Compared with the case where the elastic straps 510 are arranged in parallel and the elastic tension exists in only one direction, the elastic tension can be applied to the high voltage cabinet 200 in multiple directions, which strengthens the reinforcement effect and is beneficial to cope with complex external conditions during transportation.

[0048] Optionally, in this embodiment of the present invention, the fixing component 300 is positioned above the top surface of the high-voltage cabinet 200, and the mounting component 400 is positioned on the top surface of the high-voltage cabinet 200. Since the bottom surface of the high-voltage cabinet 200 is in contact with the bottom surface of the installation chamber, there is friction between the bottom surface of the high-voltage cabinet 200 and the bottom surface of the installation chamber, making it difficult to move. The upper part of the high-voltage cabinet 200 is far from the bottom surface and has a higher center of gravity, making it more prone to shaking and collision with the inner wall of the installation chamber during transportation. Therefore, by positioning the fixing component 300 and the mounting component 400 above the high-voltage cabinet 200 and fixing the upper part of the high-voltage cabinet 200, the high-voltage cabinet 200 can be more securely fixed, achieving an effective fixing effect.

[0049] Based on this, the two mounting positions 401 connected to one end of the two elastic straps 510 are the two farthest ends of the multiple mounting positions 401, and the distance between the two fixing positions 301 connected to the other end of the two elastic straps 510 is equal to the length of the high voltage cabinet 200. This makes the elastic tension act on the outer edge of the top of the high voltage cabinet 200, and the direction of the elastic tension is towards the center of the projection of the high voltage cabinet 200 in height, thereby improving the elastic fixing effect.

[0050] Specifically, in this embodiment of the present invention, the fixing component 300 includes a strip angle steel 310 disposed on the upper part of the rear wall. The strip angle steel 310 is provided with a plurality of evenly spaced fixing holes 320. Each fixing hole 320 can serve as a fixing position 301. One end of the elastic strap 510 passes through the fixing hole 320 and is fixed to the fixing position 301. The multiple evenly spaced fixing holes 320 are provided to facilitate the fixing of the elastic strap 510. The elastic strap 510 can be adjusted to be fixed in different fixing holes 320. The position of one end of the elastic strap 510 is changed to adapt to high-voltage switchgear 200 of different sizes. For high-voltage switchgear 200 with a longer length, the distance between the fixing positions 301 of the elastic strap 510 is increased to fix the outer edge of the high-voltage switchgear 200. For high-voltage switchgear 200 with a shorter length, the distance between the fixing positions 301 of the elastic strap 510 is decreased to keep the elastic strap 510 in a straight and taut state, with the elastic tension direction pointing towards the center of the projection of the high-voltage switchgear 200 in height, thus achieving a good fixing effect.

[0051] The mounting assembly 400 of this embodiment includes a plurality of mounting holes 402 provided on the top surface of the high voltage cabinet 200, and evenly distributed on at least one side of the top surface of the high voltage cabinet 200. A plurality of mounting positions 401 are provided in the plurality of mounting holes 402. One end of the elastic strap 510 passes through the mounting hole 402 and is fixed to the mounting position 401, so that the mounting position 401 is located at the outer edge of the top surface of the high voltage cabinet 200. The elastic tension of one end of the elastic strap 510 acts on the outer edge of the top surface of the high voltage cabinet 200, and the direction of the elastic tension is toward the center of the projection of the high voltage cabinet 200 in height, thereby improving the elastic fixing effect.

[0052] Furthermore, multiple mounting holes 402 are provided protruding from the top surface of the high-voltage cabinet 200, and the axial direction of the mounting holes 402 is parallel to the top surface of the high-voltage cabinet 200, so as to facilitate the elastic strap 510 to pass through the mounting holes 402 to complete the fixation.

[0053] In this embodiment of the utility model, the elastic strap 510 is also provided with hanging rings at both ends. The hanging rings include a buckle structure and a fixing ring. The elastic strap 510 is fixed on the fixing ring and is fastened to the mounting hole 402 or the fixing hole 320 through the buckle structure, so that the elastic strap 510 can be detachably connected to the mounting position 401 or the fixing position 301, so as to facilitate flexible adjustment of the connection position at both ends of the elastic strap 510 and change the shape of the elastic strap 510.

[0054] In other embodiments, the two ends of the elastic strap 510 can be connected to the mounting position 401 and the fixing position 301 by other structures, such as hooks provided on the mounting position 401 and the fixing position 301, and the hooks penetrate one end of the elastic strap 510 to complete the fixation.

[0055] Regarding the material of the elastic strap 510, the elastic strap 510 of this utility model embodiment is made of polyester webbing, with a safety tensile strength of 400kg, a breaking tensile strength of 800kg, and an elongation rate (the percentage of the total elongation of the material after breaking to the original gauge length) of <7%. It can play a buffering role when subjected to impact during transportation, while achieving a fixing effect.

[0056] This utility model also proposes a prefabricated substation, including the aforementioned fixing structure for the high-voltage switchgear 200, which has the advantages of the aforementioned fixing structure for the high-voltage switchgear 200, and can ensure the stability of the internal high-voltage switchgear 200 during transportation.
