Description

Technical Field

[0001] This utility model belongs to the field of electrical cabinet technology, and more specifically, it relates to a soft-start cabinet. Background Technology

[0002] In the field of power distribution and control, soft starter cabinets, bypass cabinets, and switchgear are key electrical equipment, each playing a different functional role. Traditionally, these cabinets are designed as independent units to meet operational needs in specific scenarios. Soft starter cabinets are mainly used for the smooth starting of motors, reducing the impact of starting current on the power grid by gradually adjusting the voltage; bypass cabinets provide bypass paths during uninterruptible power supply switching or maintenance, ensuring the continuity of power supply; and switchgear is responsible for the distribution and control of electrical energy, protecting circuits from overload, short circuit, and other faults.

[0003] However, with the increasing demands for space utilization in modern industry and the development of integrated and intelligent electrical equipment, traditionally independently installed soft starter cabinets, bypass cabinets, and switch cabinets have gradually revealed their large space requirements. These cabinets typically need to be installed separately, which not only occupies valuable space resources but also brings inconvenience in wiring, maintenance, and management. This problem is particularly prominent in space-constrained environments such as small factories, ships, and data centers. Utility Model Content

[0004] The purpose of this application is to provide a soft-start cabinet to solve the technical problems of existing electrical cabinets having limited functions and occupying a large space.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A soft starter cabinet is provided, including a cabinet body and a soft starter assembly, a bypass assembly, and a switch assembly installed in the cabinet body. The input terminal of the soft starter assembly is electrically connected to a power supply, and the output terminal of the soft starter assembly is connected to a load. The bypass assembly is connected in parallel with the soft starter assembly, and the switch assembly is electrically connected to the soft starter assembly and the bypass assembly. The switch assembly is used to switch between energizing the soft starter assembly and energizing the bypass assembly.

[0007] As a further improvement to the above technical solution:

[0008] Optionally, the cabinet includes a main frame, a cover plate, side plates, and a bottom plate. The cover plate covers the top of the main frame, the side plates surround the circumferential end faces of the main frame, and the bottom plate is located at the bottom of the main frame. The cover plate, side plates, and bottom plate together form an installation space for accommodating the soft starter assembly, bypass assembly, and switch assembly.

[0009] Optionally, the side panel includes an operation panel, a switch component cabinet door, and a soft starter cabinet door located on the front end face of the main frame, and the operation panel, switch component cabinet door, and soft starter cabinet door are arranged sequentially along the height direction of the main frame.

[0011] Optionally, the switch assembly includes a vacuum circuit breaker, which is installed in the installation space, and the operating terminal of the vacuum circuit breaker is positioned facing the switch assembly cabinet door.

[0012] Optionally, the cover plate includes a mounting space cabinet door located on the side end face of the main frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The soft starter cabinet provided in this application includes a cabinet and a soft starter assembly, a bypass assembly, and a switching assembly installed within the cabinet. Specifically, the soft starter assembly is configured within the cabinet, with its input directly connected to the power supply to ensure stable power input; its output is connected to the load, responsible for gradually adjusting the voltage during startup to achieve a smooth start of the load (generally a motor), effectively reducing the impact of starting current on the power grid and protecting the safe operation of the motor and power grid equipment. The bypass assembly, connected in parallel with the soft starter assembly, constitutes an important backup path for the system. When the soft starter assembly requires maintenance or fails, the bypass assembly can be connected to ensure the continuity and stability of power supply, avoiding serious consequences such as production interruptions or data loss due to equipment failure.

[0030] like Figures 1 to 3 As shown, this application provides a soft starter cabinet, including a cabinet body 1 and a soft starter assembly, a bypass assembly and a switch assembly installed in the cabinet body 1.

[0031] Specifically, the soft starter is installed in cabinet 1. Its input is directly connected to the power supply to ensure a stable power input. Its output is connected to the load and is responsible for gradually adjusting the voltage during the startup process to achieve a smooth start of the load (usually a motor), effectively reducing the impact of the starting current on the power grid and protecting the safe operation of the motor and power grid equipment.

[0032] The bypass component, connected in parallel with the soft starter, forms an important backup path for the system. When the soft starter requires maintenance or fails, the bypass component can be activated to ensure the continuity and stability of the power supply, preventing serious consequences such as production interruptions or data loss due to equipment failure.

[0033] As a key hub connecting the soft starter and bypass components, the switch assembly can be precisely controlled to quickly switch the power-on state of the soft starter and bypass components, thereby meeting the operational requirements under different working conditions and improving the flexibility and reliability of the entire system.

[0034] The soft starter cabinet provided in this application integrates the soft starter assembly, bypass assembly, and switch assembly into one unit, which not only significantly reduces the equipment footprint and simplifies the installation process, but also improves the operating efficiency and maintainability of the power system.

[0035] like Figures 1 to 3 As shown, in a specific embodiment of this application, the cabinet 1 includes a main frame 11, a cover plate 12, side panels, and a bottom plate 13. The main frame 11 serves as the skeleton of the cabinet 1, possessing sufficient strength and rigidity to support other components. The cover plate 12, placed on top of the main frame 11, not only provides sealing and protection but also ensures relative isolation of the cabinet's internal environment, preventing the intrusion of external dust, moisture, and other impurities.

[0036] Side panels are installed around the circumferential end faces of the main frame 11, providing the cabinet with a good appearance and protective performance. The base plate 13 is firmly set at the bottom of the main frame 11, serving as the base of the cabinet, supporting the weight of the entire cabinet and its internal components, and ensuring the stability of the cabinet.

[0037] The cover plate 12, side plates, and bottom plate 13 enclose an installation space for housing the soft starter assembly, bypass assembly, and switch assembly. These components are properly housed within the installation space, which not only facilitates installation and maintenance but also protects them from external environmental factors under the protection of the cabinet 1, thereby ensuring the stable operation and long-term reliability of the electrical system.

[0038] like Figures 1 to 3 As shown, in one specific embodiment of this application, the side panel includes an operation panel 14, a switch component cabinet door 15, and a soft starter cabinet door 16 located on the front end face of the main frame 11. The operation panel 14, switch component cabinet door 15, and soft starter cabinet door 16 are arranged sequentially along the height direction of the main frame 11. The operation panel 14 is located in the uppermost area of ​​the front end face of the main frame 11. This arrangement conforms to ergonomic principles, ensuring that the operator can easily and conveniently operate the equipment while maintaining an upright posture, thereby effectively improving operational comfort. The switch component cabinet door 15 is located below the operation panel 14. The main switch components of the soft starter cabinet are concentrated on the inner side of the switch component cabinet door 15, facilitating the operator to perform switching operations when needed, achieving effective control of the equipment. The soft starter cabinet door 16 is located at the bottom. This arrangement not only conforms to the usage logic of the equipment but also ensures that the soft starter components are properly protected, while facilitating necessary inspection and maintenance work by maintenance personnel.

[0039] like Figures 1 to 3 As shown, in one specific embodiment of this application, the soft starter assembly includes a soft starter 2. The soft starter 2 is installed in the installation space, and the operating end of the soft starter 2 faces the soft starter cabinet door 16. This not only allows the operator to directly and clearly access the operating interface of the soft starter 2 when opening the soft starter cabinet door 16, enabling necessary operations and adjustments, but also ensures that the overall structure of the soft starter assembly is compact and reasonable, which is beneficial to improving the overall performance and reliability of the equipment.

[0040] like Figures 1 to 3 As shown, in a specific embodiment of this application, the switch assembly includes a vacuum circuit breaker 3, which is installed in the installation space, and the operating end of the vacuum circuit breaker 3 is arranged facing the switch assembly cabinet door 15, so that the operator can directly operate the vacuum circuit breaker 3 after opening the switch assembly cabinet door 15.

[0041] like Figures 1 to 3As shown in a specific embodiment of this application, the soft starter cabinet also includes a current transformer, an overvoltage protector, a grounding switch, a zero-sequence transformer, and a vacuum contactor disposed in the installation space. The above electrical components are all applications of existing devices, and their working principles and connection relationships should be well known to those skilled in the art.

[0042] like Figures 1 to 3 As shown, in one specific embodiment of this application, the cover plate 12 includes an installation space cabinet door 17 disposed on the side end face of the main frame 11. When closed, the installation space cabinet door 17 can effectively prevent external factors such as dust and moisture from corroding the internal components of the installation space, thereby extending the service life of the equipment and maintaining its stable operation. When open, the installation space cabinet door 17 provides a convenient maintenance passage. Specifically, when it is necessary to inspect, replace, or perform routine maintenance on the components within the installation space, the operator only needs to simply open the installation space cabinet door 17 to directly expose all the functional components inside the installation space, simplifying the equipment maintenance process, reducing the time and labor costs caused by disassembling complex structures, and improving maintenance efficiency. The opening method of the installation space cabinet door 17 can be sliding, hinged, etc., which can be determined according to actual design requirements.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
