[0051] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0052] like Figures 1 to 3 As shown, the low-voltage cabinet 100 of the present application includes a cabinet body 110 and a plurality of busbars 120 arranged therein, and these busbars 120 are arranged inside the cabinet body 110 along the height direction; the low-voltage cabinet 100 also includes other substation equipment, which is not the focus of improvement in the present application and is therefore not described in detail.

[0053] As an optional solution, the cabinet body 110 includes: a frame 111 and a cabinet door 112. The frame 111 provides stable support for the substation equipment and the cabinet door 112. The cabinet door 112 is installed on the frame 111 to facilitate users to open the low-voltage cabinet 100 for maintenance and other work.

[0054] like Figure 1 to Figure 2 As shown, the low-voltage cabinet 100 of the present application further includes a vertical busbar 120 cover, in which the busbar 120 is accommodated, and the busbar 120 is protected by the vertical busbar 120 cover.

[0055] like Figure 3 to Figure 4As shown, as a specific solution, the vertical busbar 120 cover of the present application includes a mounting guide rail 210 and a cover body 220 .

[0056] Specifically, a plurality of mounting rails 210 are provided, which are fixed to the cabinet body 110 of the low-voltage cabinet 100 at intervals along the first direction Z, and can preferably be fixed to the frame 111. A plurality of cover bodies 220 are provided, and each cover body 220 is disposed between two adjacent mounting rails 210 in the first direction Z, and the mounting rails 210 limit and fix the cover body 220.

[0057] It should be noted that, in the present application, the first direction Z is a direction parallel to the extension of the busbar 120, that is, a vertical direction. The second direction X and the third direction Y are both arranged horizontally.

[0058] Preferably, the cover body 220 and the mounting rail 210 form a sliding connection in the second direction X, and the second direction X is perpendicular to the first direction Z, that is, the cover body 220 can be slid in the horizontal direction for installation, which is convenient for operation. The two mounting rails 210 located at the same position in the first direction Z are arranged at intervals and symmetrically in the third direction Y, and the third direction Y is perpendicular to the first direction Z and the second direction X. It can be understood that the two mounting rails 210 are arranged at the same height position to improve the stability of the cover body 220.

[0059] In the first direction Z, a plurality of covers 220 and mounting rails 210 are alternately stacked, so that the covers 220 and mounting rails 210 form a space for accommodating the busbar 120 .

[0060] The installation process of the vertical busbar 120 cover in the present application is: first, the installation rails 210 are arranged at different height positions (first direction Z), and then the cover body 220 is pushed between the installation rails 210 from bottom to top in sequence, so as to obtain the vertical busbar 120 cover of the required height.

[0061] By adopting the above scheme, the cover bodies 220 are stacked in sequence in the vertical direction and fixed by the pre-set mounting rails 210, so that the cover bodies 220 and the mounting rails 210 form a whole, the required protection height is obtained, and the height differences of low-voltage cabinets 100 of different specifications are flexibly adapted.

[0062] like Figures 5 to 7 , Fig.11 As shown, as a specific solution, the mounting rail 210 is formed with a guide groove 212a extending along the second direction X, and at least part of the cover body 220 is located between two adjacent guide grooves 212a in the first direction Z. In this way, the cover body 220 is limited by the guide groove 212a, and the assembly method is simple.

[0063] For the convenience of processing, the shape of the cover body 220 is generally set in a U shape, and the corresponding cover body 220 includes two side parts 221 and a middle part 222 located between the two side parts 221, wherein the guide groove 212a is adapted to the side parts 221, and the edge of the side parts 221 is limited while preventing deformation and shaking due to external forces. However, the middle part 222 without limitation is easily deformed by external forces, so that the protection effect of the middle part 222 is poor.

[0064] In order to improve the protection effect of the middle part 222, as Figures 5 to 7 , Fig.11 As shown, as an optional solution, the mounting rail 210 is formed with a limiting groove 213a extending along the third direction Y, and at least part of the cover body 220 is embedded in the limiting groove 213a. It can be understood that the edge of the middle part 222 is provided with a protrusion 222a. When the side part 221 is installed in place in the guide groove 212a, the protrusion 222a is embedded in the limiting groove 213a, and the edge of the middle part 222 is limited, which can avoid deformation and shaking due to external force, and improve the protection effect of the middle part 222.

[0065] like Figure 5 , Fig.11 As shown, as a specific solution, the mounting rail 210 includes a mounting seat 211 , a first limiting portion 212 and a second limiting portion 213 .

[0066] Specifically, the mounting seat 211 is fixed to the cabinet body 110 of the low-voltage cabinet 100 by bolt connection. One end of the first limiting portion 212 is fixedly connected to the mounting seat 211, and the other end is fixedly connected to the second limiting portion 213. The first limiting portion 212 is extended along the second direction X, and guide grooves 212a are formed on both the upper and lower sides of the first limiting portion 212. The second limiting portion 213 is extended along the third direction Y, and a limiting groove 213a is formed on a side away from the first limiting portion 212.

[0067] like Figures 3 to 5 As shown, as an optional solution, there is a spacing between the second limiting portions 213 of the two mounting rails 210 located at the same position in the first direction Z. It can be understood that a distance is reserved between the two second limiting portions 213 located at the same height position, so that when the cover body 220 is installed in place on the mounting rail 210, the upper and lower cover bodies 220 and the two second limiting portions 213 located between the two cover bodies 220 form a heat dissipation channel, thereby improving the heat dissipation effect of the vertical busbar 120 cover.

[0068] like Fig.13As shown, as another optional solution, two mounting rails 210 located at the same position in the first direction Z share the same second limiting portion 213. It can be understood that the two mounting rails 210 are used as a whole through the shared second limiting portion 213 to improve the stability of the mounting rails 210. Accordingly, the heat dissipation of the vertical busbar 120 cover is achieved through the heat dissipation holes (not shown) opened on the cover body 220.

[0069] Due to the effect of its own weight and the weight of the cover body 220 , the mounting rail 210 will partially sag downward along the first direction Z, and since the cover body 220 adopts a sheet metal structure, this will cause a portion of the cover body 220 to be compressed and deformed.

[0070] like Figure 8 As shown, as an optional solution, in the first direction Z, the maximum spacing H2 between two guide grooves 212a matched with the same cover body 220 is greater than the height H1 of the cover body 220 in the first direction Z. In this way, a distance is reserved in the first direction Z for the guide rail 210 to sag, so as to prevent the cover body 220 from being compressed and deformed.

[0071] Further, in the first direction Z, the minimum distance H3 between two guide grooves 212a matched with the same cover body 220 is smaller than the height H1 of the cover body 220 in the first direction Z. In this way, it can be ensured that the cover body 220 is always located in the guide groove 212a.

[0072] like Figure 5 , Figure 7 and Fig.10 As shown, as a preferred solution, the vertical busbar 120 cover also includes a flexible pad 230, which is arranged between the cover body 220 and the inner wall of the guide groove 212a and is made of at least silicone material or rubber material to protect the edge of the cover body 220.

[0073] like Figures 9 to 12 As shown, as an optional solution, the first limit portion 212 is provided with a through hole 212b at a portion away from the second limit portion 213, and the side portion 221 of the cover body 220 is provided with a positioning hole 221a. The vertical busbar 120 cover also includes a slide bar 241, a stopper 242, an operating member 246 and an elastic member 245.

[0074] Specifically, the slide bar 241 can be slidably inserted into the through hole 212b. The stopper 242 is screwed and fixed to one end of the slide bar 241, and is located in the space surrounded by the vertical busbar 120 cover. The operating member 246 is fixedly connected to the other end of the slide bar 241, and the operating member 246 is provided with a positioning portion 244 corresponding to the positioning hole 221a. When the cover body 220 is installed in place on the mounting guide rail 210, the positioning portion 244 can be aligned with the positioning hole 221a. The elastic member 245 is a spring, which is sleeved on the slide bar 241 and is arranged between the stopper 242 and the cover body 220. Under the action of the elastic member 245, the whole formed by the stopper 242, the slide bar 241 and the operating member 246 slides relative to the through hole 212b so that at least part of the positioning portion 244 is embedded in the positioning hole 221a.

[0075] With the above solution, through the cooperation between the positioning portion 244 and the positioning hole 221a on the cover body 220, when the cover body 220 is installed in place on the mounting rail 210, the position of the cover body 220 is limited to prevent the cover body 220 from moving backward and separating from the mounting rail 210. In addition, when the cover body 220 needs to be removed, the operating member 246 is pulled to make the positioning portion 244 withdraw from the positioning hole 221a, and the cover body 220 can be moved relative to the mounting rail and separated, which is easy to operate.

[0076] As an optional solution, a side of the second limiting portion 213 away from the stopper 242 is further provided with a slot 212c, and at least part of the operating member 246 is embedded in the slot 212c under the action of the elastic member 245. This prevents the operating member 246 from rotating relative to the second limiting portion 213, ensuring that the positioning portion 244 can be quickly aligned with the positioning hole 221a.

[0077] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
