Description

Technical Field

[0001] This utility model relates to the technical field of switching devices for power systems, and in particular to a switching device for a power supply system with grid-source, load, and energy storage. Background Technology

[0002] The term "source-grid-load-storage" refers to the four key components of a power system: power source, grid, load, and energy storage. These four components together form the framework of a modern power system, each undertaking different functions and interacting with each other to ensure the stable operation of the power system. As an important opening and closing device in the power supply system, the switch plays an important control and safety role in the power supply system.

[0003] Regarding the aforementioned technologies, it has been found that existing circuit breakers consist of a knife switch, a conductive plate, and a base. The circuit breaker lacks a corresponding shielding structure, posing a safety hazard during operation. Furthermore, after prolonged use, the circuit breaker is prone to loosening and falling off on its own. Once the circuit breaker separates from the conductive plate, it cannot guarantee the stable operation of electrical power. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a power supply system start-up and shut-down device for source-grid-load-storage power supply system.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A power supply system switching device for grid-load-storage includes a switch base, which comprises a wall base and a housing. The housing is installed on the front end face of the wall base and is fixedly connected to the wall base. A flip-open switch is installed in the housing. A blocking assembly is installed on the switch. The blocking assembly comprises a connecting seat and a baffle assembly. The connecting seat is fixedly installed on the switch, and the baffle assembly is installed at both ends of the connecting seat and is fixedly connected to the connecting seat.

[0007] As a preferred embodiment, the switch includes an insulating wrench and a conductive blade, the conductive blade being symmetrically mounted on the lower end of the insulating wrench and fixedly connected to the insulating wrench.

[0008] As a preferred embodiment, the connecting seat includes a seat plate and a side lug plate, the side lug plate being fixedly installed on the lower end face of the seat plate, and the side lug plate being fixedly connected to an insulated wrench.

[0009] As a preferred embodiment, the baffle assembly includes an arc-shaped shell and an extended baffle, wherein the arc-shaped shell is installed at the head of the extended baffle, and the arc-shaped shell and the extended baffle are integrally formed.

[0010] As a preferred embodiment, an annular plate is installed on the outer side of the arc-shaped shell and fits against the side of the seat shell. The annular plate is integrally formed with the arc-shaped shell, and an insulating flexible plate is fixedly installed at the end of the extended baffle away from the arc-shaped shell.

[0011] As a preferred embodiment, arc-shaped brackets are fixedly installed on both sides of the housing, and magnetic strips that attract the arc-shaped brackets are installed on the outer surface of the annular plate, with the magnetic strips being fixedly connected to the annular plate.

[0012] As a preferred embodiment, an auxiliary pull rod is installed on the upper end of the seat plate, and a connecting rod connected to the seat plate is also installed on the auxiliary pull rod. The two ends of the connecting rod are fixedly connected to the seat plate and the auxiliary pull rod, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This application installs a shielding component on the switch knife of the switch base, and designs the shielding component as a structure in which a connecting seat and a baffle assembly cooperate. During installation, it is fixedly installed on the outside of the switch knife through the connecting seat. In this way, during use, it can ensure that the shielding component flips and opens and closes synchronously with the switch knife, thereby achieving synchronous protection of the switch knife. This not only ensures greater safety when flipping and opening, but also, when the switch knife is closed, the baffle assembly can block the gaps in the base shell, ensuring the safety of the switch during use. Moreover, when closing, it can also prevent the switch knife from separating by suction. Furthermore, by installing an auxiliary pull plate on the shielding component, it can ensure dual-head operation when the switch knife is difficult to open, making operation easier.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, a power supply system switching device for a grid-load-storage system includes a switch base 1. The switch base 1 includes a wall base 11 and a housing 12. The housing 12 is installed on the front end face of the wall base 11 and is fixedly connected to the wall base 11. A flip-open switch 2 is installed in the housing 12. A blocking assembly 3 is installed on the switch 2. The blocking assembly 3 includes a connecting seat 31 and a baffle assembly 32. The connecting seat 31 is fixedly installed on the switch 2, and the baffle assembly 32 is installed at both ends of the connecting seat 31 and is fixedly connected to the connecting seat 31. By designing the switch base 1 as a structure in which a wall base 11 and a housing 12 cooperate, it can be directly fixed to the wall surface for installation when easy to use. The housing 12 is fixedly installed on the wall base 11 to ensure the installation of conductive plates and connection of corresponding cables. By installing a flip-open switch 2 in the housing 12, it is ensured that the switch 2 can be easily and stably flipped open and closed to start and stop the power supply system when in use. By installing a shielding component 3 on the switch 2, the conductive part of the switch 2 can be shielded when in use, which effectively increases the safety of the switch 2 when opening and closing. At the same time, by designing the shielding component 3 as a structure in which a connecting seat 31 and a baffle assembly 32 cooperate, it can be fixedly installed on the switch 2 through the connecting seat 31 when easy to use, and then shielded by the baffle assembly 32.

[0027] Reference Figure 1 and Figure 2 As shown, the switch 2 includes an insulated wrench 21 and a conductive blade 22. The conductive blade 22 is symmetrically mounted on the lower end of the insulated wrench 21, and the conductive blade 22 is fixedly connected to the insulated wrench 21. By designing the switch 2 into a structure in which the insulated wrench 21 and the conductive blade 22 cooperate, it can be used to open and close the circuit when easy to use, and the insulated wrench 21 is fixedly mounted on the head of the conductive blade 22 to facilitate safe operation when flipping the switch 2.

[0028] Reference Figure 3 , Figure 4 and Figure 5As shown, the connecting seat 31 includes a seat plate 311 and a side ear plate 312. The side ear plate 312 is fixedly installed on the lower end face of the seat plate 311 and is fixedly connected to the insulated wrench 21. By designing the connecting seat 31 with the seat plate 311 and the side ear plate 312 in a cooperating structure, the seat plate 311 can be fitted and fixed to both sides of the insulated wrench 21 by the two sets of side ear plates 312 when in use. The baffle assembly 32 includes an arc-shaped shell 321 and an extension baffle 322. The arc-shaped shell 321 is installed on the head of the extension baffle 322, and the arc-shaped shell 321 and the extension baffle 322 are integrally formed. By designing the baffle assembly 32 with the arc-shaped shell 321 and the extension baffle 322 in a cooperating structure, it is ensured that the switch 2 can be blocked by the arc-shaped shell 321 and the extension baffle 322 in use. An annular plate 323, which fits against the side of the base housing 12, is installed on the outer surface of the arc-shaped shell 321. The annular plate 323 is integrally formed with the arc-shaped shell 321. An insulating flexible plate 324 is fixedly installed at the end of the extension baffle 322 away from the arc-shaped shell 321. By installing the annular plate 323 on the outer surface of the arc-shaped shell 321 and fitting against the side of the base housing 12, it is convenient to use the annular plate 323 for limiting and clamping during use. Furthermore, by fixing the insulating flexible plate 324 at the end of the extension baffle 322 away from the arc-shaped shell 321, it is convenient for the insulating flexible plate 324 to be bent during flipping without affecting the normal flipping of the switch 2. Arc-shaped brackets 121 are fixedly installed on both sides of the base housing 12. A magnetic strip 325 that attracts the arc-shaped brackets 121 is installed on the outer surface of the annular plate 323. The magnetic strip 325 is fixedly connected to the annular plate 323. By fixing arc-shaped brackets 121 on both sides of the housing 12, the annular plate 323 on the side of the housing 12 can be auxiliaryly supported during use. Once the annular plate 323 is supported on the arc-shaped brackets 121, it can be magnetically attached to and fixed to the arc-shaped brackets 121 using magnetic strips 325. An auxiliary pull rod 313 is installed at the upper end of the seat plate 311. A connecting rod 314, which connects to the seat plate 311, is also installed on the auxiliary pull rod 313. Both ends of the connecting rod 314 are fixedly connected to the seat plate 311 and the auxiliary pull rod 313, respectively. The auxiliary pull rod 313 and the connecting rod 314 make it easier to flip and open the switch 2, facilitating better use of the equipment.

[0029] In this embodiment, the blocking component 3 can be fixedly installed on the knife gate 2 during actual use. When the knife gate 2 is flipped to close, the blocking component 3 can flip synchronously. When flipped to close, the magnetic strip 325 on the annular plate 323 adheres to the arc bracket 121, which can achieve rapid closing and limit. The magnetic attraction also prevents the knife gate 2 from flipping open on its own. At the same time, when the knife gate 2 needs to be flipped open, the operator can operate it by holding the insulated wrench 21 or by holding the auxiliary pull rod 313. It is very convenient to use.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
