[0024] The outer housing 11 is fixedly connected with a middle cover 21, which is a core structural component of the circuit breaker body 2, providing mechanical support and insulation isolation, ensuring stable installation and safe operation of internal components. The middle cover 21 can enhance the overall structural strength and insulation performance, reduce the risk of failure, and improve the service life of the equipment.

[0025] The arc chute 22 is fixedly connected with the middle cover 21, which is used to quickly extinguish the arc when the circuit breaker body 2 breaks the short-circuit current, preventing arc reignition and equipment damage. It must meet the rated short-circuit breaking capacity requirement. The arc chute 22 enhances safety and reliability, ensuring reliable breaking of the circuit breaker body 2 under short-circuit fault, reducing power outage time and equipment damage.

[0026] The driving block 16 moves to drive the switch handle 15 to rotate and in turn drive the closing handle 26 to move, which provides a manual operation interface allowing local closing and opening operation. In this embodiment, automatic closing and opening is achieved by relying on the electric operating device 1.

[0027] In the horizontal direction, the measurement module 23 is exposed outside the electric operating device 1, which is the intelligent core responsible for accurately measuring parameters such as voltage, current, active / reactive power, power factor, etc. The measurement module 23 realizes high-precision metering and real-time monitoring, supporting load management, fault diagnosis, and energy efficiency analysis. Modular design reduces downtime and maintenance costs. The measurement module 23 is exposed outside the electric operating device 1, making it easier for customers to observe and operate.

[0028] The outer housing 11 has a mounting portion 111 protruding outward in the horizontal direction, which is penetrated in the vertical direction, and the carrier box 25 is arranged in the mounting portion 111.

[0029] In this embodiment, the horizontal direction is the plane of the X and Y directions, and the vertical direction is the Z direction.

[0030] In the horizontal direction, the carrier box 25 is exposed outside the electric operating device 1. The carrier box 25 contains a carrier communication module (such as an HPLC wideband carrier), which uses a power line for data transmission, supports remote meter reading and control, the communication rate can be set, the carrier box 25 does not need additional wiring, reduces the installation cost; enhance communication reliability, especially in remote areas. Support for the "plug and play" function, automatically report device information, improve operation and maintenance efficiency.

[0031] In addition, in the present embodiment, the mounting portion 111 is additionally arranged on the outer shell 11 to accommodate and fix the carrier box 25, so that the structure of the electric operating device 1 and the circuit breaker body 2 is more compact and space-saving. The exposed carrier box 25 and the openable transparent cover plate 24 make it convenient for users to observe the working state of the carrier box 25.

[0032] The communication module includes one or more of an RS485 unit, a carrier communication unit, a micro-power wireless unit, a CAN bus unit, and a Bluetooth. The communication module is responsible for data exchange with the upper system, supports remote parameter setting, event reporting and control commands.

[0033] The additional function module includes one or more of an indication module, a human-computer interaction module, a signal output module, a temperature monitoring module, a residual current monitoring module, a safety module, and an intelligent interlocking device management module.

[0034] The additional function module expands the application scenarios and improves the safety and intelligence level. For example, the temperature monitoring module prevents overheating failure, and the safety module supports data encryption and anti-theft.

[0035] In the present embodiment, the intelligent circuit breaker 100 with the electric operating function has high modularity and interchangeability, each module supports hot plugging and interchangeability, reduces maintenance time and inventory cost, the module interface is standardized to ensure compatibility, reduces external equipment and wiring, improves installation density and aesthetics, and meets the compact size requirement.

[0036] As shown in Figures 4 to 11 The electric operating device 1 drives the movement of the switch handle 15 to realize the opening or closing of the circuit breaker body 2. The opening and closing states of the circuit breaker body 2 are usually matched with the opening and closing states of the electric operating device 1. The electric operating device 1 drives the operation block 14 to rotate by using the manual handle 13 or the electric driving assembly 17 to drive the driving block 16 to slide to realize the opening and closing of the electric operating device 1.

[0037] The cam guiding structure 102 comprises a cam shaft 1021 pivotally connected with the operation block 14, a driving bearing 1022 arranged at an end of the cam shaft 1021 away from the operation block 14, and a bearing groove 161 arranged on the driving block 16 and accommodating the driving bearing 1022.

[0038] In the embodiment, the outer shell 11 of the electric operating device 1 is made of plastic material and has a cuboid shape.

[0039] As shown in Figures 6 to 7 , the cover plate 12 is provided with a receiving cavity 125 along the thickness direction, and a taking and placing opening is arranged on one side of the cover plate 12 along the thickness direction and communicates with the receiving cavity 125. The manual handle 13 is accommodated in the receiving cavity 125 and can be taken out or put in from the taking and placing opening. In the embodiment, the receiving cavity 125 is formed in the thickness direction of the cover plate 12, so that the space in the thickness direction can be fully utilized, the idle space in the cover plate 12 is ingeniously utilized, the “misplacement” utilization of three-dimensional space is realized, and it is ensured that all functional components can be reasonably arranged under the limit size, which is the key to the successful miniaturization of the product.

[0040] Meanwhile, the manual handle 13 is stably accommodated in the cover plate 12 and becomes a part of the overall structure, which helps to improve the integrity and structural strength of the electric operating device 1 and reduce the risk of damage of the manual handle 13 caused by external impact or misoperation.

[0041] The cover plate 12 is provided with an exposure gap 122 along the vertical direction, and the exposure gap 122 is used to expose the manual handle 13 in the receiving cavity 125 along the vertical direction. By arranging the exposure gap 122, the manual handle 13 is exposed along the direction perpendicular to the cover plate 12, so that the user can take out the manual handle 13 from the exposure gap 122.

[0042] The manual handle 13 has a T shape, and the receiving cavity 125 has a T shape matched with the manual handle 13.

[0043] Further, in the embodiment, the manual handle 13 has an insertion section 131 and a handle section 132, the insertion section 131 and the handle section 132 are perpendicular to each other, and the taking and placing opening is matched with the handle section 132.

[0044] The cover plate 12 is inwardly recessed at a side away from the outer shell 11 to form a padlock operation groove 121, and the operation block 14 is formed in the padlock operation groove 121 for insertion of the manual handle 13. The operation block 14 has an operation hole 141, and the manual handle 13 is inserted into the operation hole 141 to rotate the operation block 14.

[0045] As shown in Figures 8 to 15 , the manual operation plate 101 is used to slide in the padlock operation groove 121 to shield or expose the operation hole 141.

[0046] The manual operation plate 101 slides in the padlock operation groove 121 in a direction parallel to the insertion direction of the manual handle 13, that is, in this embodiment, the extension direction of the insertion section 131 is the same as the sliding direction of the manual operation plate 101 in the padlock operation groove 121, the extension direction of the insertion section 131 is defined as the Y direction, the extension direction of the handle section 132 is the X direction, and the direction perpendicular to the cover plate 12 is the Z direction.

[0047] The electric drive assembly 17 comprises a drive motor 171, a limiting block 173 connected with the motor shaft of the drive motor 171, a gear set 172 connected with the drive motor 171, the gear set 172 is engaged with the operation block 14, the drive motor 171 works to drive the gear set 172 to work, which drives the drive block 16 to move, and further drives the switch handle 15 to perform the actions of opening and closing.

[0048] The drive block 16 can also be manually operated by manually operating the operation block 14, and the drive block 16 is moved by rotating the operation block 14, so as to realize the actions of opening and closing.

[0049] The number of guide rods 103 is two, and the two guide rods 103 are arranged on both sides of the drive block 16 and extend along the moving direction of the drive block 16, and the drive block 16 is in sliding fit with the two guide rods 103.

[0050] As shown in Figure 8 and Figure 9 The electric operation device 1 has a padlock state and an unlocked state, and the padlock block 18 is rotated to drive the electric operation device 1 to switch between the padlock state and the unlocked state.

[0051] The padlock block 18 is rotated by inserting a key into the padlock block 18 to drive the padlock block 18 to rotate, so as to switch between the padlock state and the unlocked state.

[0052] In this embodiment, the padlock block 18 is rotated to drive the padlock limiting plate 19 to move along the X direction. Specifically, the padlock block 18 is provided with a driving rod 181 which protrudes in the radial direction, the driving rod is provided with a protruding rod 182 which protrudes in the axial direction and towards the padlock limiting plate 19, the padlock limiting plate 19 is provided with a driving groove 191, and the protruding rod 182 is slidably arranged in the driving groove 191. The driving groove 191 is arc-shaped, when the padlock block 18 is rotated by 90 degrees, the protruding rod 182 slides in the driving groove 191, and drives the padlock limiting plate 19 to move along the X direction by a distance.

[0053] In this embodiment, the manual operation plate 101 is used to slide in the padlock operation groove 121 to shield or expose the operation hole 141. Only when the operation hole 141 is exposed, the manual handle 13 can be inserted into the operation hole 141 to rotate the operation block 14.

[0054] The manual operation plate 101 protrudes a limiting rod 1011 towards one side of the outer housing 11, and the cover plate 12 is provided with a clearance slot 123 for the limiting rod 1011 to pass through, the clearance slot 123 extends along the Y direction, and the padlock limiting plate 19 is provided with a first guide slot 192 extending along the X direction and a second guide slot 193 extending along the Y direction, the first guide slot 192 and the second guide slot 193 are in communication with each other, when the electric operating device 1 with the padlock anti-operation function is in the unlocked state, the limiting rod 1011 of the manual operation plate 101 is located in the second guide slot 193 and is slidably arranged, and when the electric operating device 1 is in the padlock state, the limiting rod 1011 of the manual operation plate 101 is located in the first guide slot 192 and is limited to move along the Y direction.

[0055] When the electric operating device 1 with the padlock anti-operation function is in the unlocked state, the manual operation plate 101 has a shielding state of shielding the operation hole 141 and an operation state of exposing the operation hole 141, and the manual operation plate 101 moves along the Y direction to switch between the shielding state and the operation state.

[0056] In this embodiment, the padlock state and the operation state are mechanically completely exclusive by the movement and locking of the limiting rod 1011 in the first guide slot 192 and the second guide slot 193. That is, in the padlock state, the user cannot expose the operation hole 141, and naturally cannot manually operate, which fundamentally eliminates the risk of closing the switch due to human error during maintenance.

[0057] Only in the unlocked state, the user can choose whether to move the manual operation plate 101, and then determine whether manual operation is needed.

[0058] The operation block 14 is provided with a blocking block 142 protruding radially, and the padlock limiting plate 19 is provided with a blocking slot 194 towards the operation block 14, when the electric operating device 1 is in the unlocked state, the operation block 14 can be rotated to manually open and close the switch, when in the open state, the blocking block 142 is separated from the blocking slot 194, and when in the closed state, the blocking block 142 is accommodated in the blocking slot 194, and the blocking block 142 abuts against the padlock limiting plate 19 along the X direction.

[0059] When in the closed state, the blocking block 142 is just accommodated in the blocking slot 194 and abuts against the padlock limiting plate 19 along the X direction. At this time, the padlock limiting plate 19 cannot be forcibly pressed down to padlock, and the forced logic of not being able to padlock when closing is physically realized. Only when the switch is opened, the operation block 14 is rotated, the blocking block 142 is separated from the blocking slot 194, and the padlock limiting plate 19 is released, and the padlock can be smoothly completed.

[0060] The blocking block 142 and the blocking slot 194 are both arc-shaped.

[0061] The operating block 14 is provided with a color wheel 143 along its circumference, and the cover plate 12 is provided with a transparent display window 124. The display window 124 is used to expose the color wheel 143. By rotating the operating block 14 to different positions, different colors of the color wheel 143 are exposed under the display window 124. The user can judge the opening and closing status of the circuit breaker based on the color displayed in the display window 124.

[0062] In the padlock state, in addition to limiting the position of the manual control panel 101 to prevent accidental manual operation by the user, the electric drive assembly 17 can also be limited to prevent accidental electric operation. To achieve this effect, this application provides the following two embodiments.

[0063] Example 1: like Figures 8 to 11 As shown, in this embodiment, a support block 183 is provided on the padlock block 18 along the radial direction. When the electric operating device 1 is in the padlock state, the support block 183 abuts against the limiting block 173 to restrict the rotation of the drive motor 171. When the electric operating device 1 with the padlock anti-operation function is in the unlocked state, the support block 183 rotates until it disengages from the limiting block 173.

[0064] The abutment block 183 on the padlock block 18 and the limiting block 173 abut against each other, preventing the drive motor 171 from rotating, thus preventing the drive motor 171 from rotating in the padlock state. In the unlocked state, the abutment block 183 disengages from the limiting block 173, and the drive motor 171 can rotate freely.

[0065] In this embodiment, the abutment block 183 on the padlock block 18 directly abuts against the limiting block 173, mechanically preventing the drive motor 171 from rotating in the padlock state. The structure is simple and robust, suitable for high-load applications, ensuring absolute safety and preventing misoperation in case of electronic failure.

[0066] Example 2: like Figures 16 to 17 As shown, in this embodiment, a free groove 195 and a limiting groove 196 are provided through the padlock limiting plate 19 in the vertical direction. The free groove 195 and the limiting groove 196 are connected in the X direction. When the electric operating device 1 is in the padlock state, the limiting block 173 is located in the limiting groove 196 and abuts against the padlock limiting plate 19 to limit the rotation of the drive motor 171. When the electric operating device 1 is in the unlocked state, the limiting block 173 is located in the free groove 195 and can be rotatably set.

[0067] The padlock limiting plate 19 and the limiting block 173 abut against each other, which prevents the drive motor 171 from rotating, thus preventing the drive motor 171 from rotating when the padlock is in the padlock state. When the padlock is in the unlocked state, the limiting block 173 is located in the free groove 195. The free groove 195 is large in size and does not restrict the rotation of the limiting block 173.

[0068] In this embodiment, the movement of the limiting block 173 is limited by the free slot 195 and the limiting slot 196 on the padlock limiting plate 19. In the padlocked state, the limiting block 173 is clamped into the limiting slot 196; when unlocked, it slides into the free slot 195 to allow rotation. This provides smooth operation and precise positioning, reduces wear, and enhances user experience.

[0069] The effects achieved by the above two embodiments are the same, and the main difference lies in the different positions of the abutting structure of the limiting block 173.

[0070] The limiting block 173 in the above two embodiments is in the shape of a triangular prism and is fixedly connected to the output shaft of the driving motor 171. At least one edge abuts against the edge of the abutting block 183 or the limiting slot 196, achieving the effect of limiting the rotation of the driving motor 171.

[0071] The intelligent circuit breaker 100 with electric operation function of the application adopts a highly modular design, supports hot plugging and interchanging, allows quick maintenance, upgrading and replacement of components, does not require power-off or disassembly of the entire device, significantly reduces downtime and maintenance costs, and has a compact structure. The electric operation device 1 of the application forms the receiving cavity 125 in the thickness direction of the cover plate 12, thereby fully utilizing the space in the thickness direction, and ingeniously utilizes the idle space in the cover plate 12 to accommodate the manual handle 13; the electric operation device 1 of the application realizes mechanical backup protection, ensuring that no closing operation can be performed in the padlocked state, and improving the safety level.

[0072] The technical features of the above embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present application.

[0073] The above embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for those skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are within the scope of protection of the application. Therefore, the scope of protection of the patent of the application should be subject to the appended claims.
