The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, an outdoor high-voltage integrated vacuum circuit breaker switch housing specifically includes a main housing 1 and a quick replacement component. The main housing 1 is provided with a first opening flange 2, a second opening flange 3, a base plate 4, a vent 5, an upper connection port 6 and an explosion-proof port 7. The vent 5 is provided on one side of the main housing 1, the upper connection port 5 is provided on the top of the main housing 1, the first opening flange 2 and the second opening flange 3 are provided on the front and rear sides of the main housing 1, the base plate 4 is provided at the bottom of the main housing 1, the explosion-proof port 7 is provided on one side of the main housing 1, and the quick replacement component is provided on the upper connection port 6.

The first opening flange 2 is slightly far from the main housing, while the second opening flange 3 is relatively close, which adapts to different connection requirements; the base plate 4 is located at the bottom of the main housing 1, and plays a role in supporting and stabilizing the entire equipment. At the same time, the base plate 4 may also include mounting holes or fixing devices to facilitate fixing the circuit breaker to the ground or other foundations; the air vents 5 are arranged in quadruplets on one side of the main housing 1 to balance the air pressure inside and outside the housing to prevent the housing from being damaged by pressure differences caused by temperature changes or other reasons. The air vents are usually designed to be dustproof and waterproof to ensure the cleanliness and dryness of the internal components. The upper connection port 6 is located on the top of the main housing 1 as a connection point for quick-replacement components; this interface is designed for quick and convenient installation and replacement of internal components or assemblies to improve maintenance efficiency and safety; in extreme cases, such as when an internal short circuit or fault causes a sharp increase in pressure, the explosion-proof vent 7 will automatically open to release the internal pressure, prevent the housing from rupturing or exploding, and protect the surrounding environment and personnel safety; the quick-replacement component includes a connecting shell 8, a fixing plate 9, a rotating fixing column 10 and a rotating locking assembly, and the fixing plate 9 is attached to the The fast-changing components can realize fast replacement of the internal components of the circuit breaker, reduce downtime, and improve system reliability and maintenance efficiency. The connecting shell 8 protects the internal mechanical structure and electrical connection, and provides a stable installation platform. The fixed disk 9 fits on the upper connecting port 6 to ensure the tight connection and sealing between the fast-changing components and the main shell. The fast-changing components are connected to the fixed disk 9 and fixed to the connecting shell 8 through the rotating locking assembly to realize fast installation and disassembly.

[0022] like Figure 4 and Figure 5As shown, on the basis of the above method, the rotation locking assembly includes a locking block 11, a connecting main rod 12, a limit plate 13, a limit plate 14 and a limit block 15. The connecting main rod 12 is fixed on the inner side of the connecting shell 8, and the limit plate 14 and the limit block 15 are circumferentially spaced in an array on the side of the connecting main rod 12. The connecting main rod 12 passes through the limit plate 13, and the limit plate 13 is arranged on the top of the limit plate 14 and the limit block 15. The locking block 11 is arranged on the top of the connecting main rod 12. The locking block 11 is a "U"-shaped arrangement, and symmetrical slots 16 are arranged in the locking block 11. The rotation fixing column 10 is provided with a rotation slot 17 that is engaged with the locking block 11. In implementation, the connecting main rod 12 is the core supporting structure of the rotation locking assembly on each component of the rotation locking assembly, which is fixed on the inner side of the connecting shell 8, providing a stable installation foundation for the entire assembly. The connecting main rod 12 ensures that the rotation locking assembly can maintain stable performance when subjected to external forces and torques; the limit plate 13 is arranged on the top of the limit plate 14 and the limit block 15, which plays a role in positioning and limiting the axial movement of the rotation fixing column 10, ensuring that the rotation fixing column 10 will not deviate from the preset trajectory during the rotation process, thereby ensuring the accuracy and reliability of the rotation locking, and the limit plate 14 and the limit block 15 are arranged in a circumferentially spaced array on the side of the connecting main rod 12, and their main function is to limit the rotation angle of the rotation fixing column 10 and prevent it from over-rotating. By adjusting the position and number of the limit plate 14 and the limit block 15, the rotation range of the rotation fixing column 10 can be accurately controlled to meet different locking requirements; the locking block 11 is arranged on the top of the connecting main rod 12, and is a key component for achieving locking in the rotation locking assembly. Its "U"-shaped design and the internal symmetrical card slot 16 allow for precise card connection with the rotation slot 17 on the rotation fixing column 10. When the rotation fixing column 10 rotates to a predetermined position, the locking block 11 automatically snaps into the rotation slot 17 to achieve a secure locking; the snap slot 16 is located inside the locking block 11, while the rotation slot 17 is provided on the rotation fixing column 10. The shapes and positions of the two slots are designed to match each other to ensure that the rotation fixing column 10 can be securely locked by the locking block 11 when it rotates to the correct position, thus simplifying the locking and unlocking operation process. The rotation locking assembly realizes the functions of accurately positioning the rotation fixing column 10, limiting the rotation range, preventing excessive rotation, and securely locking, thereby ensuring the stability and safety of the circuit breaker switch housing.

[0023] like Figure 4As shown, on the basis of the above method, the limit plate 14 and the limit block 15 are further abutted against one side of the rotating fixed column 10. By abutting the limit plate 14 and the limit block 15 against one side of the rotating fixed column 10, the stability of the rotating fixed column 10 during the rotation process can be increased. This design helps to reduce vibration and shaking during the rotation process, ensure that the rotating fixed column 10 remains stable during the rotation process, thereby improving the stability and reliability of the entire equipment. The design of the limit plate 14 and the limit block 15 makes the operation and maintenance of the rotating fixed column 10 easier. The operator can clearly see the rotation range of the rotating fixed column 10 and adjust it as needed. At the same time, during the equipment maintenance process, it is relatively easy to check and maintain the limit plate 14 and the limit block 15, which helps to reduce maintenance costs and improve maintenance efficiency.

[0024] like Figure 2 and Figure 3 As shown, on the basis of the above method, the fixing plate 9 is further wrapped and fixed on the upper connecting port 6. The fixing plate 9 is wrapped and fixed on the upper connecting port 6 to provide additional support and fixing for the upper connecting port 6. During the operation of the equipment, the fixing plate 9 can reduce the loosening of the connecting port caused by vibration, thereby ensuring the continuity and reliability of the connection. Through tight wrapping and fixing, the fixing plate 9 greatly reduces the risk of the upper connecting port 6 falling off due to external force. The fixing plate 9 can also play a certain protective role on the connecting port, preventing it from being directly impacted or scratched, thereby extending the service life of the connecting port. During the equipment maintenance process, the presence of the fixing plate 9 also provides convenience for the inspection and maintenance of the connecting port, allowing maintenance personnel to access and operate the connecting port more easily.

[0025] like Figure 1 As shown, on the basis of the above method, the air vents 5 are further arranged on one side of the main housing 1, and the design of the air vents allows the inside of the main housing 1 to exchange air with the outside air, thereby maintaining the circulation of the internal air. In some devices that need to dissipate heat, the air vents can also help discharge the heat generated inside, reduce the temperature of the device, allow the outside air to enter or the internal air to be discharged, thereby balancing the internal pressure and preventing equipment damage or safety hazards caused by excessive pressure.

[0026] like Figure 1 As shown, based on the above method, the distance between the first opening flange 2 and the main housing 1 is greater than the distance between the second opening flange 3 and the main housing 1. Setting the first opening flange 2 farther away can disperse the stress at the connection and reduce the risk of damage caused by stress concentration. This helps to improve the overall stability and safety of the device or system.

[0027] like Figure 2As shown, based on the above method, a rotating handle 18 is further provided on the connecting housing 8; the rotating handle 18 allows the operator to move or position the connecting housing 8 and its connected components by manual rotation. In some application scenarios where it is necessary to avoid direct contact between the hands and the inside of the equipment or dangerous areas such as high temperature and high pressure, the design of the rotating handle can reduce the possibility of the operator's hands entering the dangerous area, thereby improving the safety of the operation.

[0028] In the specific working process of the switch housing of the new outdoor high-voltage integrated vacuum circuit breaker, the main housing 1 serves as the main body of the overall structure to protect the internal electrical components from the influence of the external environment; the air vent 5 maintains the air pressure balance inside and outside the housing, while preventing dust and moisture from entering, ensuring the cleanliness and dryness of the internal components; the first opening flange 2 and the second opening flange 3 are respectively connected to the incoming and outgoing cables or other electrical equipment to realize the transmission and control of electric energy; the base plate 4 supports and stabilizes the entire device, and may include mounting holes or fixing devices to facilitate the fixing of the circuit breaker to the ground or other foundations. Internal component quick replacement process: When the internal components of the circuit breaker need to be replaced or maintained, first unlock the rotary locking assembly by turning the handle 18 or other tools, and the rotary fixing column 10 can be rotated to disengage the fixed connection with the connecting housing 8 after releasing the lock of the locking block 11; the rotary fixing column 10 is connected to the fixing plate 9, so the fixing plate 9 will also be removed together, thereby exposing the upper connection port 6 and the components inside it. At this time, the components that need to be replaced or maintained can be easily removed and replaced or repaired. After the replacement or repair is completed, the new or repaired component is installed on the upper connection port 6, and the fixing plate 9 is re-attached to the upper connection port 6. The rotating fixing column 10 is realigned with the connection housing 8 and locked by rotating the locking assembly. The locking block 11 will be snapped into the rotating notch 17 on the rotating fixing column 10 to achieve a secure lock. Safety protection mechanism In extreme cases, such as when an internal short circuit or fault causes a sharp increase in pressure, the explosion-proof vent 7 will automatically open to release the internal pressure, prevent the shell from rupturing or exploding, and protect the surrounding environment and personnel safety. Continuous monitoring and maintenance Regularly check whether the dustproof and waterproof functions of the air vent 5 are intact, and whether the explosion-proof vent 7 is in normal condition. Regularly check whether the connection of the incoming and outgoing cables is firm, and whether the base plate 4 is stably fixed. If necessary, regularly replace and maintain internal components through quick replacement components to ensure the long-term stable operation of the circuit breaker.
