[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] In the description of this application, it should be understood that the terms "height," "thickness," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "multiple" means two or more, and at least one can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "vertical" means completely perpendicular to 90° or almost completely perpendicular, for example, an angle within the range of 85° to 95° is considered vertical.
[0030] It should also be noted that in the accompanying drawings of the embodiments of this application, the arrow marked X indicates the first direction of the cabinet, the arrow marked Y indicates the second direction of the cabinet, and the arrow marked Z indicates the height direction of the cabinet. The first direction X, the second direction Y, and the height direction Z are introduced to more clearly illustrate the structure and relative position of each component in the distribution cabinet. In practical applications, the first direction X, the second direction Y, and the height direction Z may change depending on the placement of the distribution cabinet.
[0031] As a preamble to the embodiments of this application, existing switch cabinets and control cabinets are usually designed independently, each cabinet requires a certain amount of space, and due to redundant design, some space in each cabinet is not used, which increases the volume of the cabinet. In addition, some cables need to be connected to the cabinet from the outside, which increases the cabinet's occupation of horizontal space. As a result, the switch cabinet and control cabinet occupy a large amount of space and have low space utilization.
[0032] Please combine them together Figure 1 and Figure 5 The power distribution cabinet in this embodiment includes a cabinet body 1, a switch assembly 2, and a control assembly 3. The cabinet body 1 has a first compartment 11, a second compartment 13, a first opening 12 connecting the first compartment 11, and a second opening 14 connecting the second compartment 13. The first compartment 11 and the second compartment 13 are arranged along a first direction X, which is the length direction of the cabinet body 1. The first opening 12 and the second opening 14 are located on the same side of the cabinet body 1. When a user faces the first opening 12 and the second opening 14, the first compartment 11 and the second compartment 13 correspond to the user's left and right sides, respectively, and are arranged side by side.
[0033] At least a portion of the switch assembly 2 is disposed in the first compartment 11, and another portion is disposed in the second compartment 13; that is, the switch assembly 2 includes multiple components, some of which are disposed in the first compartment 11 and connected to the cabinet 1, and the other portion is disposed in the second compartment 13 and connected to the cabinet 1. The control assembly 3 is disposed in the second compartment 13.
[0034] The components in the switch cabinet form the switch assembly 2, while the components in the control cabinet form the control assembly 3. Integrating the components in both the switch cabinet and the control cabinet into a single cabinet 1 fully utilizes the internal space of the cabinet 1. Furthermore, the wiring between the switch assembly 2 and the control assembly 3 can be arranged inside the cabinet 1, reducing the space occupied by cables located outside the cabinet 1 and improving the space utilization rate of the cabinet 1. The first opening 12 and the second opening 14 are located on the same side, allowing workers to conveniently perform installation or maintenance work on one side, reducing the number of workstation changes and helping to improve work efficiency.
[0035] Specifically, the cabinet 1 is equipped with a partition along its height direction Z, which divides the internal space of the cabinet 1 into a first compartment 11 and a second compartment 13, thereby separating the components in space and reducing electrical interference.
[0036] Please combine them together Figure 1 and Figure 2 In some embodiments, the switch assembly 2 includes a secondary electrical component 21, which may include relay protection, measurement and control, metering, and other automatic devices. These devices enable precise control, monitoring, and measurement of the circuit, ensuring the safe operation of the equipment. The distribution cabinet also includes a secondary compartment 4, located within the first compartment 11 or the second compartment 13. The secondary compartment 4 has a receiving cavity 43 and a third opening 44 communicating with the receiving cavity 43. The third opening 44 and the first opening 12 are located on the same side facing the cabinet 1. The secondary electrical component 21 is housed within the receiving cavity 43. The secondary compartment 4 integrates the secondary electrical component 21, reducing dispersion and improving space utilization. Furthermore, it isolates the secondary electrical component 21 from the external environment, reducing electrical interference. The third opening 44 and the first opening 12 being on the same side facilitate installation, maintenance, or observation by personnel on the same side.
[0037] Specifically, the secondary chamber 4 can be located on the top side of the first compartment 11 or on the top side of the second compartment 13.
[0038] Please combine them together Figure 1 and Figure 2 In some embodiments, the secondary chamber 4 is located on the side of the cabinet 1 near the first opening 12, or the secondary chamber 4 is located on the side of the cabinet 1 near the second opening 14. The secondary chamber 4 being located near the first opening 12 or the second opening 14, that is, at the front of the cabinet 1, allows it to avoid being obstructed by other components, enabling direct observation by personnel, and also provides sufficient operating space during installation or maintenance.
[0039] Please refer to Figure 2 In some embodiments, the secondary chamber 4 includes a first panel 41 and a plurality of second panels 42. The plurality of second panels 42 are arranged around the outer periphery of the first panel 41 and connected end to end. Each second panel 42 is vertically connected to the first panel 41. The first panel 41 and the plurality of second panels 42 form a receiving cavity 43 and a third opening 44. The plurality of second panels 42 can be spliced together to form various shapes to adapt to the space in which the secondary chamber 4 is located and avoid interference with surrounding components. The first panel 41 and the second panel 42 can be made of corrosion-resistant metal and can be processed using sheet metal technology to ensure the strength of the secondary chamber 4. The corrosion-resistant metal can be stainless steel, aluminum alloy, etc., to meet the needs of the power distribution cabinet in different environments and to improve the electromagnetic shielding effect.
[0040] Please combine them together Figure 1 and Figure 3 In some embodiments, the switch assembly 2 includes a reactor 22, which is disposed within the first compartment 11 and supported on the inner bottom wall of the cabinet 1. The reactor 22 is heavy; supporting it on the inner bottom wall of the cabinet 1 lowers its center of gravity and increases the overall stability of the cabinet 1.
[0041] In this embodiment, the secondary chamber 4 is arranged in the first compartment 11 and above the reactor 22, so as to realize the arrangement in the height direction Z of the cabinet 1, which reduces the requirement for the lateral dimension of the cabinet 1 and helps to save the space occupied by the cabinet 1 in the lateral direction.
[0042] Please combine them together Figure 2 and Figure 3 In some embodiments, the switch assembly 2 further includes a contactor 23 and a circuit breaker 24. The contactor 23 is located in the first compartment 11 and above the reactor 22, while the circuit breaker 24 is located in the second compartment 13 and is positioned opposite the contactor 23. During wiring, the main circuit enters from the bottom of the first compartment 11, passes through the reactor 22, then through a medium-voltage cable to the contactor 23, and finally through the contactor 23 to the circuit breaker 24. The overall wiring is L-shaped. The reactor 22 and contactor 23, as well as the contactor 23 and circuit breaker 24, are directly connected, which reduces the required cable length, facilitates integrated layout, and improves space utilization.
[0043] In this embodiment, the reactor 22, contactor 23 and secondary chamber 4 are arranged sequentially along the height direction Z of the cabinet 1, while the contactor 23 and secondary chamber 4 are staggered in the first direction X.
[0044] Please combine them together Figure 2 and Figure 4 In some embodiments, the cabinet 1 includes an inner side 15, which is positioned opposite to the second opening 14 in a second direction Y, where Y is the width direction of the cabinet 1. A control component 3 is positioned below the circuit breaker 24, spaced apart from the inner side 15, forming a cable compartment 16. When a cable enters the circuit breaker 24, it passes through the copper busbar into the cable compartment 16 and exits from the bottom of the second compartment 13 via a medium-voltage cable. The cable compartment 16 provides space for cable routing, facilitating cable management and isolating high-voltage and low-voltage circuits within the distribution cabinet, thus improving electrical safety. Furthermore, because the circuit breaker is positioned relatively high, roughly at eye level, it is easier to observe during routine inspections, allowing for timely assessment of its operational status and reducing safety risks.
[0045] Please refer to Figure 5In some embodiments, the control component 3 includes a controller 31 and a DC power module 32, the DC power module 32 being electrically connected to the controller 31. The controller 31 is used for functions such as receiving input signals, executing program logic, controlling output actions, monitoring and protection, and data processing and communication.
[0046] Existing control cabinets typically use UPS power supplies. However, due to the complex internal structure of UPS power supplies and the need for additional battery packs and control systems, they require considerable space for installation, resulting in a relatively large size. This application uses a DC power module 32 instead of a UPS to power the controller 31. The internal structure and function of a DC power module are relatively simple, resulting in a smaller size that is easier to integrate into the cabinet layout.
[0047] In some embodiments, an anti-corrosion coating is provided on the outer side of the DC power module 32. The anti-corrosion coating is formed on the surface of the DC power module 32 using ALD (atomic layer deposition) technology. The anti-corrosion coating enables the DC power module 32 to resist corrosion in marine salt spray environments, thereby meeting the different working environment requirements of the power distribution cabinet.
[0048] Accordingly, the electrical equipment provided in this application includes the power distribution cabinet of the above embodiment. Therefore, the electrical equipment can have all the technical features and beneficial effects of the power distribution cabinet, which will not be repeated here.
[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0050] The power distribution cabinet and electrical equipment provided in the embodiments of this application have been described in detail above, and specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application.
