Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, specifically to a disconnecting switch and switch cabinet. Background Technology

[0002] Disconnecting switches in switchgear serve to isolate power sources, perform switching operations, and connect and disconnect low-current circuits.

[0003] Most existing disconnect switches are suitable for switch cabinets with larger internal spaces, such as vertical switch cabinets. In switch cabinets with smaller internal spaces, such as drawer-type switch cabinets, the disconnect switch itself occupies a lot of space, making it inconvenient to wire between the disconnect switch and the switch cabinet. It is necessary to wind the wire to achieve electrical connection, which further increases the space occupied by the disconnect switch in the switch cabinet and affects the coordinated use of the disconnect switch and the switch cabinet.

[0004] Therefore, there is an urgent need to propose a disconnecting switch to solve the problems in the existing technology. Utility Model Content

[0005] The purpose of this application is to provide a disconnecting switch and switch cabinet that can optimize the structure of the disconnecting switch to reduce its space occupation.

[0006] In a first aspect, embodiments of this application provide a disconnecting switch, including a rotating shaft, a first wiring busbar and a second wiring busbar, the first wiring busbar being disposed on a first side wall of the disconnecting switch, the second wiring busbar being disposed on a second side wall of the disconnecting switch, and the rotating shaft being disposed on either the first side wall or the second side wall.

[0007] Based on the above embodiments of this application, by jointly setting the rotating shaft and the first wiring busbar on the first side wall of the disconnecting switch, the portion of the rotating shaft extending out of the first housing and the portion of the first wiring busbar extending out of the second housing are located on the same side of the disconnecting switch. That is, the rotating shaft and the first wiring busbar occupy the same part of the space in the switch cabinet, effectively reducing the space occupied by the rotating shaft set separately on other sides of the disconnecting switch and improving the space utilization rate in the switch cabinet.

[0008] In one optional embodiment, the extending direction of the rotating shaft on the first side wall is the same as the extending direction of the first busbar, or the extending direction of the rotating shaft on the second side wall is the same as the extending direction of the second busbar. The first side wall and the second side wall are two opposite side walls of the disconnecting switch.

[0009] Based on the above embodiments of this application, the rotating shaft and the first busbar extend away from the first sidewall of the disconnecting switch, and the rotating shaft and the first busbar extend in the same direction. This arrangement can prevent the rotating shaft or the first busbar from extending to other directions, ensuring that the rotating shaft and the first busbar are in the same space, thereby reducing the space occupied by the disconnecting switch.

[0010] In one alternative embodiment, the rotating shaft and the first busbar are spaced apart on the first sidewall and are arranged side by side; or, the rotating shaft and the second busbar are spaced apart on the second sidewall and are arranged side by side.

[0011] Based on the embodiments described above, the rotating shaft and the first busbar are spaced apart on the first side wall, providing sufficient space between them and preventing interference. Simultaneously, the rotating shaft and the first busbar are arranged side-by-side on the first side wall, causing their space occupies in the switchgear to partially overlap, further saving space occupied by the disconnector switch and facilitating its assembly. Similarly, the rotating shaft and the second busbar, spaced apart and arranged side-by-side on the second side wall, achieve the same technical effects as the aforementioned embodiments, and will not be repeated here.

[0012] In one optional embodiment, the disconnecting switch further includes a third sidewall and a fourth sidewall, which are two adjacent sidewalls on the disconnecting switch, and both the third sidewall and the fourth sidewall are adjacent to the first sidewall and the second sidewall. Mounting feet are provided on the third sidewall and / or the fourth sidewall.

[0013] Based on the embodiments described above, the use of mounting feet to fix and connect the disconnector and the switchgear has the advantages of simple structure, convenient installation, and small size. Different mounting foot positions correspond to different installation directions of the disconnector, which helps to expand the applicability of the disconnector.

[0014] In one alternative embodiment, multiple mounting feet are provided, and the multiple mounting feet are spaced apart at the edges of the third sidewall and / or the fourth sidewall.

[0015] Based on the embodiments described above, the disconnecting switch is fixedly connected to the cabinet via multiple mounting feet, which enhances the installation stability and reliability of the disconnecting switch. Furthermore, the multiple mounting feet are spaced apart at the edges of the third or fourth side wall, facilitating the fixing and connection operation, improving connection efficiency, and further enhancing the installation stability of the disconnecting switch.

[0016] In one optional embodiment, the first busbar is disposed on the first sidewall along the width direction of the first sidewall, and the second busbar is disposed on the second sidewall along the width direction of the second sidewall; or, the first busbar is disposed on the first sidewall along the length direction of the first sidewall, and the second busbar is disposed on the second sidewall along the length direction of the second sidewall.

[0017] Based on the embodiments described above, regardless of whether the first busbar is arranged along the width or length of the first sidewall, it can be connected to a corresponding terminal block in the switchgear for horizontal wiring. This facilitates wiring without taking up excessive space in the switchgear, thus expanding the applicability of the disconnector. Similarly, the second busbar can be arranged in the same or different manner as the first busbar, further expanding the applicability of the disconnector.

[0018] Secondly, embodiments of this application also provide a switch cabinet, including a cabinet body, an operating mechanism, a terminal block, and the aforementioned disconnecting switch. The disconnecting switch is disposed in the cabinet body, the operating mechanism is connected to a rotating shaft, and the terminal block is electrically connected to a first busbar and a second busbar.

[0019] Based on the above embodiments of this application, the switch cabinet structure with the operating mechanism and terminal block located on the same side of the cabinet is more compact. In the assembly with the disconnecting switch, only the connection operation needs to be performed on the same side of the cabinet, which simplifies the assembly operation and improves the assembly efficiency.

[0020] Meanwhile, the disconnecting switch adapted to this type of switchgear, by placing the rotating shaft and the first or second busbar on the same side, opposite to the side of the cabinet where the operating mechanism and terminal block are located, facilitates the connection between the rotating shaft and the operating mechanism, and also facilitates the connection between the first and second busbars and the terminal block. This further simplifies the assembly operation between the disconnecting switch and the switchgear, and the one-to-one wiring between the first and second busbars and the terminal block reduces the use of conductive wires, thereby reducing the space occupied by conductive wires in the cabinet.

[0021] In one alternative embodiment, the cabinet includes a horizontally arranged base plate and a plurality of side plates arranged vertically around the base plate. The operating mechanism and the terminal block are arranged on the same side plate, and the side plate on which the operating mechanism and the terminal block are arranged is opposite to one of the first side wall or the second side wall on which a rotating shaft is arranged.

[0022] Based on the embodiments described above, the base plate is horizontally arranged so that the disconnecting switch can be installed onto the base plate from a direction perpendicular to the base plate. The operating mechanism and terminal block are arranged on a side plate perpendicular to the base plate, and a rotating shaft is provided in one of the first or second side walls in a position opposite to that side plate. This facilitates horizontal wiring between the disconnecting switch and the switch cabinet. This arrangement simplifies the assembly operation between the disconnecting switch and the switch cabinet, and horizontal wiring between two opposite side walls simplifies wiring operations and saves wiring costs.

[0023] In one alternative embodiment, the base plate is opposite to the third side wall, and one of the side plates is opposite to the fourth side wall. The disconnecting switch can be mounted on the base plate by mounting feet provided on the third side wall, and / or, the disconnecting switch can be mounted on the side plate by mounting feet provided on the fourth side wall.

[0024] Based on the embodiments described above, this diverse installation method increases the installation flexibility of the switchgear. For example, in different installation scenarios, the disconnecting switch can be installed on the base plate or the side plate according to the actual space and wiring requirements.

[0025] In one alternative embodiment, the terminal block is electrically connected to the first and second busbars via copper busbars, which are arranged horizontally.

[0026] Based on the embodiments described above, the terminal block is electrically connected to the first and second busbars via copper busbars. The horizontal arrangement of the copper busbars helps reduce resistance and energy loss, ensuring efficient current transmission. The horizontal arrangement also simplifies installation and maintenance. Furthermore, the horizontal wiring between the disconnector and the switchgear reduces the need for winding connections, helping to reduce the amount of copper busbars used, thereby reducing the space occupied by the copper busbars in the switchgear and saving costs.

The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] A disconnecting switch generally consists of two parts: a switching mechanism and a switch body. The switching mechanism includes a rotating shaft, and the switch body includes a busbar. Switchgear typically includes an operating mechanism and a terminal block. The operating mechanism is connected to the switching mechanism via the rotating shaft, and the terminal block is electrically connected to the switch body via the busbar.

[0042] In existing disconnect switches, the rotating shaft and the busbar are located on different sides of the switch. Both the rotating shaft and the busbar occupy space within the switch cabinet, making existing disconnect switches mostly suitable only for switch cabinets where the operating mechanism and the terminal block are located on different sides and the internal space is large. However, in a special type of switch cabinet, such as a drawer-type switch cabinet, where the operating mechanism and the terminal block are located on the same side, existing disconnect switches not only occupy a large amount of space but also present wiring difficulties, requiring winding wires to achieve electrical connections. This further increases the space occupied by the disconnect switch within the switch cabinet and affects the coordinated use of the disconnect switch and the switch cabinet.

[0043] Based on this, embodiments of this application provide a disconnecting switch and a switch cabinet, which can optimize the structure of the disconnecting switch, reduce the space occupied by the disconnecting switch, and simplify the assembly method of the disconnecting switch.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 3 This application provides a switch cabinet 1, including a cabinet body 11, an operating mechanism 12, a terminal block 13, and a disconnect switch 2. The disconnect switch 2 is disposed in the cabinet body 11. The operating mechanism 12 is connected to the rotating shaft 211. The terminal block 13 is electrically connected to the first busbar 221 and the second busbar 222.

[0046] The cabinet 11 serves as the mounting base for the operating mechanism 12, the terminal block 13, and the disconnect switch 2, ensuring the stability and safety of the installation of these components.

[0047] The operating mechanism 12 is used for manual operation to control the working status of the switchgear 1. (Refer to...) Figure 2 The operating mechanism 12 includes an operating handle 121 located on the outside of the cabinet 11 and a transmission component 122 connected to the operating handle 121 and extending into the cabinet 11. The operating handle 121 is used for manual operation, and the transmission component 122 is used to transmit the force received by the operating handle 121. The portion of the transmission component 122 away from the operating handle 121 is connected to the rotating shaft 211 of the disconnect switch 2 to realize the transmission connection between the operating mechanism 12 and the disconnect switch 2.

[0048] Reference Figure 1 and Figure 3 Terminal block 13 is used to connect external circuits to the internal circuits of switch cabinet 1. Terminal block 13 and operating handle 121 are located on the same side of cabinet 11. The portion of terminal block 13 near the interior space of cabinet 11 is electrically connected to the first busbar 221 and the second busbar 222 of disconnecting switch 2, and the portion of terminal block 13 near the exterior of cabinet 11 is electrically connected to the external circuit, so as to realize the connection and isolation functions of disconnecting switch 2.

[0049] Based on the above embodiments of this application, the switch cabinet 1 with the operating mechanism 12 and the terminal block 13 located on the same side of the cabinet 11 has a more compact structure. In the assembly with the disconnecting switch 2, only the connection operation needs to be performed on the same side of the cabinet 11, which simplifies the assembly operation and improves the assembly efficiency.

[0050] Meanwhile, the disconnecting switch 2 adapted to this type of switch cabinet 1, by setting the rotating shaft 211 and the first wiring busbar 221 or the second wiring busbar 222 on the same side, and opposite to the side of the cabinet 11 where the operating mechanism 12 and the terminal block 13 are set, facilitates the connection between the rotating shaft 211 and the operating mechanism 12, and facilitates the connection between the first wiring busbar 221 and the second wiring busbar 222 and the terminal block 13. This further simplifies the assembly operation between the disconnecting switch 2 and the switch cabinet 1, and the one-to-one wiring of the first wiring busbar 221 and the second wiring busbar 222 and the terminal block 13 reduces the use of conductive wires, thereby reducing the space occupied by conductive wires in the cabinet 11.

[0051] In this embodiment, the transmission component 122 is a transmission shaft. The transmission shaft and the rotating shaft 211 are directly linked and cooperated, which has the advantages of simple assembly, simple transmission and high efficiency, and is conducive to quick and accurate control of the on and off of the disconnecting switch 2.

[0052] In an alternative embodiment, the transmission connection between the operating mechanism 12 and the rotating shaft 211 can also be a gear drive, chain drive, or other methods. For example, in some applications requiring high precision, a gear drive may be chosen to ensure operational accuracy and stability. In cases where cost and maintenance requirements are less stringent, a chain drive may be a more economical option.

[0053] Furthermore, the terminal block 13 is electrically connected to the first busbar 221 and the second busbar 222 via electrical connectors, which can be conductive copper busbars 14 or wires, etc. To ensure a good electrical connection, the conductive connectors and the busbars can be connected by bolting, crimping, or welding. For example, bolting may be a better choice in cases requiring frequent disassembly and maintenance. However, welding may be a more suitable method in situations where connection stability is extremely important.

[0054] Please refer to Figure 4 and Figure 5 This embodiment provides a disconnecting switch 2, including a rotating shaft 211, a first wiring busbar 221 and a second wiring busbar 222. The first wiring busbar 221 is disposed on the first side wall 23 of the disconnecting switch 2, and the second wiring busbar 222 is disposed on the second side wall 24 of the disconnecting switch 2. The first side wall 23 and the second side wall 24 are two opposite side walls on the disconnecting switch 2, and the rotating shaft 211 is disposed on the first side wall 23 or the second side wall 24.

[0055] Reference Figure 4 The disconnecting switch 2 provided in this embodiment is a low-voltage disconnecting switch 2, which typically includes two parts: a switching mechanism 21 and a switch body 22. The rotating shaft 211 is part of the switching mechanism 21, and the first busbar 221 and the second busbar 222 are both parts of the switch body 22.

[0056] The switching mechanism 21 is connected to the operating mechanism 12 of the switch cabinet 1 via the rotating shaft 211. The switching mechanism 21 can change the direction of the force transmitted from the operating mechanism 12 to the rotating shaft 211, and then transmit the force to the switch body 22 to control the on / off state of the switch body 22.

[0057] The switch body 22 is electrically connected to the terminal block 13 of the switch cabinet 1 through the first busbar 221 and the second busbar 222 to form an internal circuit in the switch cabinet 1. After being connected to the external main circuit, it can play the role of connecting or isolating current through the operation of the operating mechanism 12.

[0058] Specifically, refer to Figure 4 The switching mechanism 21 includes a first housing and a switching component disposed within the first housing. A rotating shaft 211 passes through the first wall of the first housing. The portion of the rotating shaft 211 located inside the first housing is connected to the switching component, and the portion of the rotating shaft 211 located outside the first housing is connected to the operating mechanism 12.

[0059] The switch body 22 includes a second housing and a contact assembly disposed within the second housing. A first busbar 221 passes through the first wall of the second housing. The portion of the first busbar 221 located inside the second housing is connected to the contact assembly, and the portion of the first busbar 221 located outside the second housing is connected to the terminal block 13.

[0060] The second busbar 222 passes through the second wall of the second housing. The portion of the second busbar 222 inside the second housing is connected to the contact assembly, and the portion of the second busbar 222 outside the second housing is connected to the terminal block 13. The first busbar 221 and the second busbar 222 are electrically connected to different terminal blocks 13 to form a circuit.

[0061] Additionally, refer to Figure 4The switching mechanism 21 and the switch body 22 are arranged side by side, that is, the switch body 22 is arranged along the width direction of the switching mechanism 21, and the first wall surface of the first housing and the first wall surface of the second housing are on the same plane to form the first side wall 23 of the disconnecting switch 2. Similarly, the second wall surface of the first housing and the second wall surface of the second housing are on the same plane to form the second side wall 24 of the disconnecting switch 2.

[0062] Based on the above embodiments of this application, by jointly arranging the rotating shaft 211 and the first wiring busbar 221 on the first side wall 23 of the disconnecting switch 2, the portion of the rotating shaft 211 extending out of the first housing and the portion of the first wiring busbar 221 extending out of the second housing are located on the same side of the disconnecting switch 2. That is, the rotating shaft 211 and the first wiring busbar 221 occupy the same part of the space in the switch cabinet 1, effectively reducing the space occupied by the rotating shaft 211 if it is set separately on other sides of the disconnecting switch 2, and improving the space utilization rate in the switch cabinet 1.

[0063] Meanwhile, the rotating shaft 211 and the first wiring busbar 221 are located on the same side of the disconnecting switch 2, which can be adapted to the switch cabinet 1 where the operating mechanism 12 and the terminal block 13 are located on the same side, simplifying the assembly operation of the disconnecting switch 2 in the switch cabinet 1 and improving the assembly efficiency.

[0064] Of course, the rotating shaft 211 can also be installed together with the second wiring busbar 222 on the second side wall 24 of the disconnecting switch 2, which has the same technical effect as the above-mentioned scheme, and will not be described in detail here.

[0065] In one alternative embodiment, the disconnect switch 2 includes a switching mechanism 21 and at least one switch body 22, the switching mechanism 21 and the at least one switch body 22 are arranged side by side, and the switching mechanism 21 is drivenly connected to each switch body 22.

[0066] The presence of at least one switch body 22 indicates that there can be one or more switch bodies 22, and the specific number of switch bodies 22 can be set according to the actual use of the isolating switch 2. In this embodiment, four switch bodies 22 are provided, which are arranged side by side with the switching mechanism 21, and the four switch bodies 22 are arranged in pairs on both sides of the switching mechanism 21.

[0067] In addition, the switching mechanism 21 is connected to the switch body 22 arranged side by side through the switching component, so as to transmit the action of the operating mechanism 12 to the switch body 22 and realize the control of the switch body 22 to turn on and off.

[0068] In some examples, refer to Figure 2The cabinet 11 includes a horizontally arranged base plate 111 and a plurality of side plates 112 arranged vertically around the base plate 111. The operating mechanism 12 and the terminal block 13 are arranged on the same side plate 112. The side plate 112 on which the operating mechanism 12 and the terminal block 13 are arranged is opposite to one of the rotating shafts 211 arranged in the first side wall 23 or the second side wall 24.

[0069] Reference Figure 2 The base plate 111 is typically used to mount the disconnector switch 2. Multiple side plates 112, which are vertically arranged around the base plate 111, together with the base plate 111, form the cabinet 11. The horizontal cross-section of the base plate 111 is usually rectangular or square, that is, there are generally 4 side plates 112. Of course, the base plate 111 can also be set to other shapes, as long as the number of side plates 112 matches the number of sides of the base plate 111.

[0070] Based on the embodiments described above, the base plate 111 is horizontally arranged so that the disconnecting switch 2 can be installed on the base plate 111 from a direction perpendicular to the base plate 111. The operating mechanism 12 and the terminal block 13 are arranged on the side plate 112 perpendicular to the base plate 111, and a rotating shaft 211 is provided in the first side wall 23 or the second side wall 24 in a position opposite to the side plate 112. This facilitates horizontal wiring between the disconnecting switch 2 and the switch cabinet 1. This arrangement simplifies the assembly operation between the disconnecting switch 2 and the switch cabinet 1, and the horizontal wiring between the two opposite side walls simplifies the wiring operation and saves wiring costs.

[0071] Specifically, refer to Figure 1 When the rotating shaft 211 is mounted on the first side wall 23, during the assembly of the disconnecting switch 2 onto the base plate 111, the first side wall 23 can be adjusted to a position opposite to the side plate 112 where the operating mechanism 12 and the terminal block 13 are mounted. This shortens the distance between the rotating shaft 211 and the operating mechanism 12, as well as the distance between the first busbar 221 and the terminal block 13, which is beneficial for the stable control of the disconnecting switch 2 by the operating mechanism 12 and facilitates the corresponding connection between the terminal block 13 and the first busbar 221. Similarly, when the rotating shaft 211 is mounted on the second side wall 24, it has the same technical effect as in the aforementioned embodiment.

[0072] In addition, this layout makes it easier for operators to operate and maintain the equipment. For example, when it is necessary to debug the operating mechanism 12 or inspect the terminal block 13, the operator can directly face the relevant components without having to go around to other parts of the cabinet 11.

[0073] Reference Figure 4 and Figure 5In some examples, the extension direction of the shaft 211 on the first sidewall 23 is the same as the extension direction of the first busbar 221. Alternatively, the extension direction of the shaft 211 on the second sidewall 24 is the same as the extension direction of the second busbar 222.

[0074] Based on the above embodiments of this application, the rotating shaft 211 and the first busbar 221 extend away from the first sidewall 23 on the disconnecting switch 2, and the rotating shaft 211 and the first busbar 221 extend in the same direction. This arrangement can prevent the rotating shaft 211 or the first busbar 221 from extending to other directions, ensuring that the rotating shaft 211 and the first busbar 221 are in the same space, thereby reducing the space occupied by the disconnecting switch 2.

[0075] Furthermore, this arrangement ensures that the rotating shaft 211 will not interfere with the wiring busbar, and that the connection between the rotating shaft 211 and the operating mechanism 12 will not affect the connection between the first wiring busbar 221 and the terminal block 13, thereby improving the reliability and assembly stability of the disconnecting switch 2. Similarly, the fact that the rotating shaft 211 and the second wiring busbar 222 extend in the same direction on the second side wall 24 has the same technical effect as the aforementioned arrangement, and will not be repeated here.

[0076] Specifically, if the rotating shaft 211 and the first busbar 221 are both mounted on the first side wall 23, the first side wall 23 is opposite to the side plate 112 in the switch cabinet 1 where the operating mechanism 12 and the terminal block 13 are located, and both the rotating shaft 211 and the first busbar 221 extend toward the side plate 112 relative to the first side wall 23. If the rotating shaft 211 and the second busbar 222 are both mounted on the second side wall 24, the second side wall 24 is opposite to the side plate 112 in the switch cabinet 1 where the operating mechanism 12 and the terminal block 13 are located, and both the rotating shaft 211 and the second busbar 222 extend toward the side plate 112 relative to the second side wall 24.

[0077] Reference Figure 4 and Figure 5 In some examples, the rotating shaft 211 and the first busbar 221 are spaced apart on the first sidewall 23 and are arranged side by side; or, the rotating shaft 211 and the second busbar 222 are spaced apart on the second sidewall 24 and are arranged side by side.

[0078] Based on the embodiments described above, the rotating shaft 211 and the first busbar 221 are spaced apart on the first sidewall 23, providing sufficient space between them and preventing interference. Simultaneously, the rotating shaft 211 and the first busbar 221 are arranged side-by-side on the first sidewall 23, causing their space occupies in the switchgear 1 to partially overlap, further saving space occupied by the disconnector switch 2 in the switchgear 1 and facilitating its assembly. Similarly, the rotating shaft 211 and the second busbar 222 are spaced apart and arranged side-by-side on the second sidewall 24, achieving the same technical effects as the aforementioned embodiments, and will not be repeated here.

[0079] Specifically, the rotating shaft 211 is disposed on the first wall of the first housing, the first busbar 221 is disposed on the first wall of the second housing, and the switching mechanism 21 and the switch body 22 are disposed side by side. Therefore, the first housing and the second housing are adjacent to each other, that is, the rotating shaft 211 and the first busbar 221 are spaced apart, which can reduce the risk of interference between the rotating shaft 211 and the first busbar 221.

[0080] Furthermore, the rotating shaft 211 is located at the middle of the first wall surface on the first housing, and the first wiring busbar 221 is located at the middle of the first wall surface on the second housing, so that the rotating shaft 211 and the first wiring busbar 221 are arranged side by side at a distance from each other at the middle of the first side wall 23.

[0081] The rotating shaft 211 is positioned at the center of the first side wall 23. This allows for a more uniform distribution of force across the switching mechanism 21 when subjected to the force transmitted by the operating mechanism 12, reducing damage to the disconnecting switch 2 caused by force imbalance. For example, if the rotating shaft 211 is off-center, it may generate additional torque during operation, increasing the risk of failure of the switching mechanism 21. Positioning the rotating shaft 211 at the center of the second side wall 24 achieves the same technical effect as positioning it at the center of the first side wall 23.

[0082] The first busbar 221 is arranged side by side in the middle of the first side wall 23. This facilitates wiring operations and allows for greater overlap with the space occupied by the rotating shaft 211, thus improving the space utilization rate in the switch cabinet 1.

[0083] Reference Figure 4 and Figure 5 In some examples, the disconnecting switch 2 also includes a third sidewall 25 and a fourth sidewall 26, which are two adjacent sidewalls on the disconnecting switch 2, and both the third sidewall 25 and the fourth sidewall 26 are adjacent to the first sidewall 23 and the second sidewall 24. Mounting feet 27 are provided on the third sidewall 25 and / or the fourth sidewall 26.

[0084] Mounting feet 27 are provided on the third side wall 25 and / or the fourth side wall 26 for fixing the disconnecting switch 2 inside the switch cabinet 1. The mounting feet 27 enable the disconnecting switch 2 to be stably installed on the inner wall of the switch cabinet 1, avoiding displacement caused by vibration or operation.

[0085] Based on the embodiments described above, the disconnector switch 2 and switch cabinet 1 are fixedly connected using mounting feet 27, which has the advantages of simple structure, convenient installation, and small size. Different mounting positions of the mounting feet 27 correspond to different installation directions of the disconnector switch 2, which helps to expand the applicability of the disconnector switch 2.

[0086] The third side wall 25 and the fourth side wall 26 are adjacent, meaning that the disconnect switch 2 can be fixedly connected to either of the two adjacent side panels 112 inside the cabinet 11. In this embodiment, the third side wall 25 is the bottom wall of the disconnect switch 2, and the fourth side wall 26 is a wall surface that is simultaneously adjacent to the bottom wall, the first side wall 23, and the second side wall 24.

[0087] Reference Figure 2 In some examples, the base plate 111 is opposite to the third side wall 25, and one of the side plates 112 is opposite to the fourth side wall 26. The disconnecting switch 2 can be mounted on the base plate 111 by means of the mounting feet 27 provided on the third side wall 25, and / or, the disconnecting switch 2 can be mounted on the side plate 112 by means of the mounting feet 27 provided on the fourth side wall 26.

[0088] Based on the embodiments described above, this diverse installation method increases the installation flexibility of the switch cabinet 1. For example, in different installation scenarios, the disconnector switch 2 can be installed on the base plate 111 or the side plate 112 according to the actual space and wiring requirements.

[0089] The third side wall 25 can be fixedly connected to the base plate 111 of the cabinet 11 via mounting feet 27, and the fourth side wall 26 can be fixedly connected to the side plate 112 of the cabinet 11 via mounting feet 27. When the disconnecting switch 2 is assembled to the cabinet 11, it can be fixedly connected in two directions simultaneously or in only one direction, both of which can achieve stable installation.

[0090] For example, the mounting feet 27 can be made of rubber material with good shock absorption to reduce the impact of vibration generated during operation of the disconnecting switch 2 on its performance.

[0091] Reference Figure 5 In some examples, multiple mounting feet 27 are provided, and the multiple mounting feet 27 are spaced apart at the edges of the third sidewall 25 and / or the fourth sidewall 26.

[0092] Based on the embodiments described above, the disconnect switch 2 is fixedly connected to the cabinet 11 by a plurality of mounting feet 27, which can enhance the installation stability and reliability of the disconnect switch 2. Meanwhile, the plurality of mounting feet 27 are spaced apart at the edges of the third side wall 25 or the fourth side wall 26, which facilitates the fixing and connection operation, improves connection efficiency, and further enhances the installation stability of the disconnect switch 2.

[0093] Reference Figures 4 to 6 In some examples, the first busbar 221 is disposed on the first sidewall 23 along the width direction of the first sidewall 23, and the second busbar 222 is disposed on the second sidewall 24 along the width direction of the second sidewall 24; or, the first busbar 221 is disposed on the first sidewall 23 along the length direction of the first sidewall 23, and the second busbar 222 is disposed on the second sidewall 24 along the length direction of the second sidewall 24.

[0094] Based on the embodiments described above, regardless of whether the first busbar 221 is arranged along the width or length of the first sidewall 23, it can be connected to the corresponding terminal block 13 in the switch cabinet 1 for horizontal wiring. This facilitates wiring without taking up too much space in the switch cabinet 1, thus expanding the applicability of the disconnector switch 2. Similarly, the second busbar 222 can be arranged in the same or different manner as the first busbar 221, further expanding the applicability of the disconnector switch 2.

[0095] The specific orientation of the first busbar 221 and the second busbar 222 can be selected according to different circuit layouts and space requirements. For example, in situations where space is limited, the busbars can be set along the width direction to save space; while in situations where high current carrying capacity is required, they can be set along the length direction to increase the contact area.

[0096] In some examples, terminal block 13 is electrically connected to first busbar 221 and second busbar 222 via copper busbar 14, which is horizontally positioned.

[0097] Based on the embodiments described above, the terminal block 13 is electrically connected to the first busbar 221 and the second busbar 222 via a copper busbar 14. The horizontal arrangement of the copper busbar 14 helps reduce resistance and energy loss, ensuring efficient current transmission. The horizontal arrangement also simplifies installation and maintenance. Furthermore, the horizontal wiring between the disconnector 2 and the switch cabinet 1 reduces the need for winding connections, thus reducing the amount of copper busbar 14 used, thereby reducing the space occupied by the copper busbar 14 in the switch cabinet 1 and saving costs.

[0098] The material and size of the copper busbar 14 are selected based on the current and heat dissipation requirements. For example, for high-current applications, a thicker copper busbar 14 may be chosen to reduce resistance and heat generation; while in cases where space is limited, a thinner copper busbar 14 with an appropriate width will be chosen to meet current requirements while saving space.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
