Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an intelligent circuit breaker with electric operation function. Background Technology

[0002] Traditional molded case circuit breakers (MCCBs) rely entirely on manual operation for opening and closing. While common in early power distribution systems, this method is inefficient, slow, and requires significant manpower and resources, especially in high-frequency or emergency situations. With the rapid development of smart grids and increasing automation demands, the market urgently needs MCCBs capable of reliably and automatically opening and closing to support remote monitoring, fault diagnosis, and energy efficiency management. Consequently, electrically operated devices designed for use with MCCBs have emerged. These devices receive remote commands (such as via RS485 or carrier communication) to automatically drive the circuit breaker to open or close, reducing manual intervention, improving operational convenience and system intelligence, and are widely used in residential power consumption, industrial power distribution, and smart distribution areas.

[0003] However, existing circuit breakers and manual operating devices need to be purchased and installed separately, and the internal structure of the circuit breaker is relatively dispersed, making maintenance and replacement more complicated.

[0004] In view of this, it is necessary to improve the existing molded case circuit breakers to solve the above problems. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1 to 17 As shown, the intelligent circuit breaker 100 with electric operation function of this utility model includes a circuit breaker body 2 and an electric operation device 1.

[0022] like Figures 1 to 3As shown, the circuit breaker body 2 includes a middle cover 21, an arc extinguishing cover 22 disposed on the side of the middle cover 21 away from the electric operating device 1, a closing handle 26 disposed on the side of the middle cover 21 facing the electric operating device 1, a measurement module 23 disposed on the side of the middle cover 21 facing the electric operating device 1, a carrier box 25, a transparent cover plate 24 disposed on the side of the carrier box 25 facing the electric operating device 1, a communication module, a power supply module for providing power, a power quality detection module for performing power quality detection, and an additional function module.

[0023] like Figures 4 to 17 As shown, the electric operating device 1 includes a housing 11, a cover plate 12 disposed on one side of the housing 11, a manual handle 13, an operating block 14, a switch handle 15, a drive block 16 for driving the switch handle 15 to switch, an electric drive assembly 17 for driving the drive block 16 to slide, a padlock block 18 for padlock operation, a padlock limiting plate 19, a manual operating plate 101, a cam guide structure 102, and a guide rod 103.

[0024] The electric operating mechanism 1 supports manual / automatic mode switching and has a mechanical locking function to prevent accidental operation. The electric operating module adopts a plug-in terminal design, which enables quick installation and remote control.

[0025] The outer casing 11 is fixedly connected to the middle cover 21. The middle cover 21, as the core structural component of the circuit breaker body 2, provides mechanical support and insulation, ensuring stable installation and safe operation of internal components. The middle cover 21 enhances overall structural strength and insulation performance, reduces the risk of failure, and extends equipment life. Its modular design allows for quick docking with other modules, supports hot-swapping, and facilitates maintenance and upgrades.

[0026] The arc-extinguishing cover 22 is fixedly connected to the middle cover 21. The arc-extinguishing cover 22 is used to quickly extinguish the arc when the circuit breaker body 2 interrupts the short-circuit current, preventing arc reignition and equipment damage. It must meet the rated short-circuit breaking capacity requirements. The arc-extinguishing cover 22 improves safety and reliability, ensuring that the circuit breaker body 2 reliably interrupts the short-circuit fault, reducing power outage time and equipment damage.

[0027] The drive block 16 moves to rotate the switch handle 15, which in turn moves the closing handle 26. The closing handle 26 provides a manual operation interface, allowing local opening and closing operations. In this embodiment, automatic opening and closing is achieved by relying on the electric operating device 1.

[0028] Horizontally, the measurement module 23 is exposed on the outside of the electric operating device 1. The measurement module 23 is the intelligent core, responsible for accurately measuring parameters such as voltage, current, active / reactive energy, and power factor. The measurement module 23 achieves high-precision metering and real-time monitoring, supporting load management, fault diagnosis, and energy efficiency analysis. Its modular design reduces downtime and maintenance costs. The exposed location of the measurement module 23 on the outside of the electric operating device 1 also facilitates customer observation and operation.

[0029] The outer casing 11 has a mounting part 111 that protrudes outward in the horizontal direction and extends through the vertical direction. The carrier box 25 is disposed inside the mounting part 111.

[0030] In this embodiment, the horizontal direction is the plane containing the X and Y directions, and the vertical direction is the Z direction.

[0031] Horizontally, the carrier box 25 is exposed on the outside of the electrically operated device 1. The carrier box 25 houses a carrier communication module (such as an HPLC broadband carrier), which uses power lines for data transmission, supports remote meter reading and control, and has a configurable communication rate. The carrier box 25 requires no additional wiring, reducing installation costs; it also enhances communication reliability, especially in remote areas. It supports on-demand data collection, automatically reporting equipment information and improving maintenance efficiency.

[0032] The power quality detection module has the ability to monitor voltage, frequency, harmonics, etc. It can detect abnormalities such as voltage sag and reverse phase sequence, and supports event logging, such as overvoltage and undervoltage events.

[0033] In addition, in this embodiment, an additional mounting part 111 is provided on the outer casing 11 to make way for and fix the carrier box 25, making the structure of the electric operating device 1 and the circuit breaker body 2 more compact and saving space. The exposed carrier box 25 and the openable transparent cover 24 make it easy for the user to observe the working status of the carrier box 25.

[0034] The communication module includes one or more of the following: RS485 unit, carrier communication unit, low-power wireless unit, CAN bus unit, and Bluetooth. The communication module is responsible for data exchange with the upper-level system, supporting remote parameter setting, event reporting, and control commands. It enables bidirectional communication and remote management, supports smart grid applications, and has strong anti-interference capabilities. Remote opening and closing and status feedback are achieved through the RS485 unit, reducing the need for additional communication terminals.

[0035] Additional functional modules include one or more of the following: indicator module, human-machine interaction module, signal output module, temperature monitoring module, residual current monitoring module, safety module, and smart IoT lock management module.

[0036] Additional functional modules expand application scenarios and enhance security and intelligence. For example, a temperature monitoring module prevents overheating failures, and a security module supports data encryption and anti-theft measures.

[0037] In this embodiment, the intelligent circuit breaker 100 with electric operation function features optimized layout and modular integration, significantly reducing installation space. It boasts high modularity and interchangeability, with each module supporting hot-swapping and interchangeability, reducing maintenance time. The integrated design lowers material, installation, and maintenance costs. Standardized module interfaces ensure compatibility, reduce external equipment and wiring, and improve installation density and aesthetics, meeting compact size requirements. The active power consumption of the voltage line in non-communication mode is ≤1.5W, and in communication mode it is ≤8W, far lower than the total power consumption of multiple independent devices, conforming to the green energy-saving concept.

[0038] The intelligent circuit breaker 100 with electric operation function has successfully replaced the combination of circuit breaker, power metering equipment, power quality detection equipment, multi-mode communication equipment and electric operating mechanism through highly integrated functions. It has shown significant advantages in many dimensions such as space occupation, cost reduction and green energy saving, and improved the reliability and intelligence level of the system. It is suitable for low-voltage distribution areas and other scenarios.

[0039] like Figures 4 to 11 As shown, the electric operating device 1 opens or closes the circuit breaker body 2 by moving the switch handle 15. 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 uses a manual handle 13 or an electric drive assembly 17 to drive the operating block 14 to rotate, thereby causing the drive block 16 to slide, thus realizing the opening and closing of the electric operating device 1.

[0040] The cam guide structure 102 includes a camshaft 1021 pivotally connected to the operating block 14, a drive bearing 1022 disposed at the end of the camshaft 1021 away from the operating block 14, and a bearing groove 161 on the drive block 16 for receiving the drive bearing 1022.

[0041] In this embodiment, the outer shell 11 of the electric operating device 1 is made of plastic material and is cubic in shape.

[0042] like Figures 6 to 7 As shown, a receiving cavity 125 is formed in the cover plate 12 along the thickness direction. A pick-and-place opening communicating with the receiving cavity 125 is formed on one side of the cover plate 12 along the thickness direction. The manual handle 13 is received in the receiving cavity 125 and can be taken out or put in through the pick-and-place opening. In this embodiment, the receiving cavity 125 is formed in the thickness direction of the cover plate 12, thereby making full use of the space in the thickness direction and cleverly utilizing the idle space in the cover plate 12. This achieves the "misalignment" utilization of three-dimensional space, ensuring that all functional components can be reasonably arranged under extreme dimensions, which is the key to the successful miniaturization of the product.

[0043] Meanwhile, the manual handle 13 is securely housed inside the cover plate 12, becoming 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 to the manual handle 13 due to external collisions or misoperation.

[0044] An exposure notch 122 is provided on the cover plate 12 along the vertical direction to expose the manual handle 13 inside the receiving cavity 125 along the vertical direction. By providing the exposure notch 122, the manual handle 13 is exposed in the direction perpendicular to the cover plate 12, making it convenient for the user to remove the manual handle 13 from the exposure notch 122.

[0045] The manual handle 13 is T-shaped, and the receiving cavity 125 is T-shaped to match the manual handle 13.

[0046] Furthermore, in this embodiment, the manual handle 13 has an insertion section 131 and a handle 132, the insertion section 131 and the handle 132 are perpendicular to each other, and the take-up and put-out opening matches the handle 132.

[0047] The side of the cover plate 12 away from the outer shell 11 is recessed inward to form a padlock operation groove 121. An operation block 14 is formed in the padlock operation groove 121 for the manual handle 13 to be inserted. The operation block 14 has an operation hole 141, and the manual handle 13 is used to insert into the operation hole 141 to rotate the operation block 14.

[0048] like Figures 8 to 15 As shown, the manual control panel 101 is slidable within the padlock operation slot 121 to cover or expose the operation hole 141.

[0049] The sliding direction of the manual operation plate 101 in the padlock operation slot 121 is 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 slot 121. In this embodiment, the extension direction of the insertion section 131 is defined as the Y direction, the extension direction of the handle 132 is defined as the X direction, and the direction perpendicular to the cover plate 12 is defined as the Z direction.

[0050] The electric drive assembly 17 includes a drive motor 171, a limit block 173 connected to the motor shaft of the drive motor 171, and a gear set 172 connected to the drive motor 171. The gear set 172 meshes with the operating block 14. When the drive motor 171 is working, it can drive the gear set 172 to work, which can drive the drive block 16 to move, thereby driving the switch handle 15 to perform the opening and closing actions.

[0051] The drive block 16 can also be manually operated by the operator block 14. By rotating the operator block 14, the drive block 16 can be moved, thereby realizing the opening and closing of the gate.

[0052] There are two guide rods 103. 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. The drive block 16 and the two guide rods 103 are in sliding engagement.

[0053] like Figure 8 and Figure 9 As shown, the electric operating device 1 has a padlock state and an unlocked state, and the padlock block 18 rotates to drive the electric operating device 1 to switch between the padlock state and the unlocked state.

[0054] By inserting a key into the padlock block 18 to rotate it, the padlock state and the unlocked state can be switched.

[0055] In this embodiment, the padlock block 18 rotates to drive the padlock limiting plate 19 to move along the X direction. Specifically, the padlock block 18 has a drive rod 181 protruding radially, and the drive rod has a protruding rod 182 protruding axially toward the padlock limiting plate 19. The padlock limiting plate 19 has a groove 191, and the protruding rod 182 is slidably disposed within the drive groove 191. The drive groove 191 is arc-shaped. When the padlock block 18 rotates 90 degrees, the protruding rod 182 slides within the drive groove 191, causing the padlock limiting plate 19 to move a certain distance along the X direction.

[0056] In this embodiment, the manual control plate 101 is slidable in the padlock operation slot 121 to cover or expose the operation hole 141. The manual handle 13 can only be inserted into the operation hole 141 to rotate the operation block 14 when the operation hole 141 is exposed.

[0057] A limiting rod 1011 protrudes from the side of the manual operation plate 101 facing the outer shell 11. A clearance groove 123 is provided on the cover plate 12 for the limiting rod 1011 to pass through. The clearance groove 123 extends in the Y direction. A first guide groove 192 extending in the X direction and a second guide groove 193 extending in the Y direction are provided through the padlock limiting plate 19. The first guide groove 192 and the second guide groove 193 are interconnected. When the electric operating device 1 with 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 groove 193 and can be slidably set. 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 groove 192 and is restricted from moving in the Y direction.

[0058] When the electric operating device 1 with padlock anti-operation function is in the unlocked state, the manual operating plate 101 has a blocked state that covers the operating hole 141 and an operating state that exposes the operating hole 141. The manual operating plate 101 moves along the Y direction to switch between the blocked state and the operating state.

[0059] In this embodiment, the movement and locking of the limiting rod 1011 within the first guide groove 192 and the second guide groove 193 completely exclude the padlock state and the operation state mechanically. That is, in the padlock state, the user cannot expose the operation hole 141, and naturally cannot perform manual operation, thus fundamentally eliminating the risk of accidental closing of the circuit breaker due to human error during maintenance.

[0060] Only when the device is unlocked can the user choose whether to move the manual control panel 101, and thus determine whether manual operation is required.

[0061] A blocking block 142 is provided on the operating block 14 along the radial direction. A blocking groove 194 is provided on the side of the padlock limiting plate 19 facing the operating block 14. When the electric operating device 1 is in the unlocked state, the operating block 14 can be rotated to manually open and close the gate. When in the open state, the blocking block 142 is disengaged from the blocking groove 194. When in the closed state, the blocking block 142 is housed in the blocking groove 194. The blocking block 142 abuts against the padlock limiting plate 19 in the X direction.

[0062] When the circuit is closed, the blocking block 142 is precisely contained within the blocking groove 194 and abuts against the padlock limiting plate 19 in the X direction. At this time, it is impossible to forcibly press down the padlock limiting plate 19 to perform padlocking, thus physically implementing the logic that padlocking is prohibited when the circuit is closed. Only when the circuit is opened and the operating block 14 rotates, causing the blocking block 142 to disengage from the blocking groove 194, is the padlock limiting plate 19 released, allowing it to be smoothly pressed down to complete the padlocking process.

[0063] Both the blocking block 142 and the blocking groove 194 are arc-shaped.

[0064] 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.

[0065] 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.

[0066] Example 1: like Figures 8 to 11As 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] In this embodiment, the movement of the limiting block 173 is restricted by the free groove 195 and the limiting groove 196 on the padlock limiting plate 19. In the padlock state, the limiting block 173 engages with the limiting groove 196 for support; when unlocked, it slides into the free groove 195 to allow rotation. This provides smooth operation and precise positioning, reduces wear, and enhances the user experience.

[0072] The two embodiments described above achieve the same effect, and the main difference lies in the different positions of the abutment structure of the limiting block 173.

[0073] In the two embodiments described above, the limiting block 173 is triangular prism-shaped and fixedly connected to the output shaft of the drive motor 171. At least one edge abuts against the edge of the supporting block 183 or the limiting groove 196, thereby limiting the rotation of the drive motor 171.

[0074] The intelligent circuit breaker 100 with electric operation function of this utility model adopts a highly modular design, supports hot-swapping and interchangeability, and allows for rapid maintenance, upgrades and component replacement without power outages or disassembly of the entire device, significantly reducing downtime and maintenance costs, and has a compact structure. The electric operation device 1 of this utility model, by forming the receiving cavity 125 in the thickness direction of the cover plate 12, can make full use of the space in the thickness direction, and cleverly utilizes the idle space in the cover plate 12 to accommodate the manual handle 13; the electric operation device 1 of this utility model achieves mechanical backup protection, ensuring that no closing operation can be performed in the padlock state, thereby improving the safety level.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
