Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a dual-redundant drive type adaptive dual-speed circuit breaker. Background Art

[0002] The dual-redundant drive adaptive dual-speed circuit breaker is a high-end circuit breaker that integrates redundant design, adaptive control and dual-speed breaking capability. It is mainly used to improve the reliability, safety and fault handling efficiency of the power system. The dual-redundant drive system is a redundant configuration achieved through two independent drive mechanisms (such as electromagnetic drive, permanent magnet drive or spring energy storage drive). The two drive systems can work simultaneously or serve as backup for each other. The adaptive dual-speed breaking mechanism refers to the dual-speed breaking logic. The circuit status is monitored in real time through built-in sensors (such as current, voltage, temperature sensors), combined with micro-processing. The processor algorithm dynamically determines the type and severity of the fault and automatically matches the breaking speed. When the circuit breaker is closed, the operating mechanism (such as a manual handle or an electric energy storage spring) drives the contacts to close. The main contacts and arcing contacts contact in sequence (arcing contacts first, main contacts later). Ultimately, the main contacts carry the rated current and conduct. When the circuit breaker is opened, the operating mechanism drives the contacts to separate, and the current is transferred to the arcing contacts. As the gap increases, an arc is generated. The arc extinguishing chamber quickly extinguishes the arc by blowing the arc, splitting the arc, etc. Ultimately, the contacts remain in the disconnected position to form a sufficient insulation gap.

[0003] Traditional circuit breakers do not lock the touch panel when the push handle is in the disengaged state. The touch panel should be firmly stuck when closing the circuit to avoid "self-closing and self-tripping" due to vibration or external force. The touch panel should be in the released state after opening the circuit to prevent jamming during the next operation. If the circuit breaker is opened due to overload, short circuit or other faults, the cause of the fault must be checked first (such as whether the line is still short-circuited). Since the touch panel is not locked, the staff may make an error and force closing the circuit without eliminating the fault, resulting in a secondary fault. In traditional circuit breakers, the high temperature of the arc vaporizes the contact metal (such as copper and silver), which forms metal particles after condensation. These may be deposited on the arc extinguishing grid or the insulation surface, causing surface discharge or phase-to-phase short circuit. It is necessary to manually open the inspection port of the arc extinguishing chamber and wipe the metal particles in the gap and surface of the grid with a dust-free cloth dipped in anhydrous alcohol.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original dual-redundant drive type adaptive dual-speed circuit breaker. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 9The present invention provides a technical solution: a dual-redundant drive type adaptive dual-speed circuit breaker, comprising a main body 1, a touch plate 2 is arranged inside the main body 1, a connector 3 is fixed on one side of the touch plate 2, a locking assembly is arranged on one side of the connector 3, a sliding column 5 is arranged on one side of the locking assembly, the sliding column 5 is connected to a screw rod 6 through a thread, a first bevel gear 7 is fixed on one side of the screw rod 6, a second bevel gear 8 is meshed with one side of the first bevel gear 7, and the bottom end of the second bevel gear 8 is fixedly connected to the output end of the motor through a rotating shaft, a cleaning assembly is arranged on the top of the second bevel gear 8, a plurality of arc extinguishing grids 12 are arranged at equal distances inside the main body 1, a cleaning plate 10 is arranged between every two arc extinguishing grids 12, a moving assembly is arranged inside the cleaning plate 10, two connecting plates 13 are fixed to the bottom of the arc extinguishing grid 12, and the connecting plate 13 consists of an inclined plate and a vertical plate, and a collecting plate 14 is slidably connected between the two connecting plates 13.

[0022] In the specific implementation, the touch plate 2 in the main body 1 cooperates with the locking assembly through the connecting piece 3, and the starting motor drives the second bevel gear 8 to rotate. The meshing first bevel gear 7 causes the screw 6 to rotate, driving the sliding column 5 to move, driving the locking assembly and the connecting piece 3 to complete the locking. At the same time, the second bevel gear 8 drives the top cleaning assembly to move up and down and horizontally. When the touch plate 2 is unlocked, the electric push rod pushes the silicone plate 111 out of the cleaning plate 10, and the arc extinguishing grid 12 is cleaned by a compound motion under the drive of the moving frame 904, and impurities slide to the collection plate 14 through the connecting plate 13.

[0023] As a further implementation scheme of the present invention, the locking assembly includes a positioning column 401 placed inside the connecting member 3, the connecting member 3 is provided with a cavity for placing the positioning column 401, a base 402 is fixed on the top of the positioning column 401, a lock buckle 404 is connected to the protruding position of the outer wall of the base 402 through a rotating shaft, a connecting column 405 is fixed on the top of the base 402, and the connecting column 405 is slidably connected to the sliding column 5.

[0024] In the specific implementation, the motor drives the screw 6 to move the sliding column 5, driving the connecting column 405 and the base 402 slidably connected to it to move synchronously. The positioning column 401 on the base 402 is inserted into the cavity of the connecting member 3. When the sliding column 5 continues to move, its inclined surface pushes the lock buckle 404 to rotate around the rotating axis of the base 402, and engages with the protruding position of the connecting member 3 to achieve locking. When unlocking, the sliding column 5 moves in the opposite direction, the inclined surface disengages the lock buckle 404, and the positioning column 401 exits the cavity to complete the unlocking.

[0025] As a further embodiment of the present invention, a first spring 403 is provided between the base 402 and the lock 404 , one end of the first spring 403 is fixedly connected to the outer wall of the base 402 , and the other end of the first spring 403 is fixedly connected to the inner wall of the lock 404 .

[0026] In a specific implementation, the first spring 403 between the base 402 and the lock buckle 404 is compressed and stores energy when locked. When the sliding column 5 pushes the lock buckle 404 to rotate and engage with the connecting member 3 through the inclined surface, the spring is compressed and stores elastic potential energy. When unlocking, the inclined surface of the sliding column 5 disengages, and the first spring 403 releases energy to push the lock buckle 404 to rotate in the opposite direction, so that it disengages from the connecting member 3, thereby realizing automatic resetting and unlocking of the lock buckle 404.

[0027] As a further embodiment of the present invention, a sliding rod 406 is slidably connected in the connecting column 405, and the connecting column 405 is provided with a cavity for sliding with the sliding rod 406, and the sliding column 5 is provided with a cavity for placing the sliding rod 406.

[0028] In a specific implementation, the sliding rod 406 in the connecting column 405 can slide in its cavity, and the sliding rod 406 is also placed in the cavity of the sliding column 5. When the sliding column 5 moves, the connecting column 405 and the base 402 are driven to move synchronously through the sliding rod 406. After the positioning column 401 is engaged with the connecting member 3, the sliding column 5 continues to move and compresses the second spring 407 between the sliding rod 406 and the sliding column 5, so that the sliding column 5 and the base 402 form an elastic linkage, ensuring buffering and force transmission when the lock buckle 404 is rotated and locked.

[0029] As a further implementation scheme of the present invention, the sliding column 5 is provided with a cavity for cooperating with the base 402 and the connecting column 405 to move, and a second spring 407 is arranged between the base 402 and the sliding column 5. One end of the second spring 407 is fixedly connected to the sliding column 5, and the other end of the second spring 407 is fixedly connected to the base 402.

[0030] In a specific implementation, the cavity opened by the sliding column 5 allows the base 402 and the connecting column 405 to move therein, and the second spring 407 between the two produces an elastic effect when the sliding column 5 drives the base 402 to move: when the positioning column 401 is inserted into the connecting member 3, the sliding column 5 continues to move and compresses the second spring 407, storing elastic potential energy to provide a reset force for subsequent unlocking. At the same time, the spring is used for buffering during the locking process to avoid damage to components caused by rigid collision, thereby ensuring the smoothness of the locking and unlocking actions.

[0031] As a further implementation scheme of the present invention, the cleaning assembly includes a threaded rod 901 fixed to the top of the second bevel gear 8, a lifting column 902 is sleeved on the outer wall of the threaded rod 901, a fixed plate 903 is fixed to the top of the lifting column 902, the fixed plate 903 is slidingly limited and connected to a movable frame 904, and one side of the movable frame 904 is fixedly connected to the cleaning plate 10.

[0032] In the specific implementation, the rotation of the second bevel gear 8 drives the top threaded rod 901 to rotate, causing the sleeved lifting column 902 to move axially along the threaded rod 901, and then drives the mobile frame 904 to rise and fall vertically through the fixed plate 903. The mobile frame 904 simultaneously drives the cleaning plate 10 fixed thereto to move up and down between the arc extinguishing grids 12, providing vertical power for cleaning the arc extinguishing grids 12.

[0033] As a further implementation scheme of the present invention, a connecting shaft 905 is fixed on one side of the protruding position of the movable frame 904, the connecting shaft 905 is slidably connected to the limiting plate 906, and the bottom end of the limiting plate 906 is fixedly connected to the inner wall of the main body 1, and the limiting plate 906 is provided with a sliding groove 907, and the sliding groove 907 is wavy.

[0034] In the specific implementation, the connecting shaft 905 on the movable frame 904 slides with the wavy slide groove 907 of the limit plate 906. When the lifting column 902 drives the movable frame 904 to move vertically, the connecting shaft 905 slides along the wavy slide groove 907, so that the movable frame 904 produces horizontal displacement while moving vertically, thereby driving the cleaning plate 10 to perform a vertical and horizontal composite movement between the arc extinguishing grid pieces 12, thereby enhancing the cleaning effect of the arc extinguishing grid pieces 12.

[0035] As a further implementation scheme of the present invention, the moving component includes a silicone plate 111 arranged on both sides of the cleaning plate 10, the cleaning plate 10 is provided with a cavity for sliding with the silicone plate 111, an inclined block 112 is fixed on one side of the silicone plate 111, a push block 113 is provided on one side of the inclined block 112, and the contact surface between the push block 113 and the inclined block 112 is an inclined surface, a connecting frame 114 is fixed on the top of the push block 113, and one side of the connecting frame 114 is fixedly connected to the electric push rod.

[0036] In the specific implementation, the electric push rod pushes the connecting frame 114 to drive the push block 113 to move. The push block 113 contacts the inclined block 112 through the inclined surface. The inclined surface transmission is used to make the inclined block 112 drive the silicone plate 111 to slide in both directions in the cavity of the cleaning plate 10. When cleaning is required, the push block 113 pushes the inclined block 112 to make the silicone plate 111 extend out of the cleaning plate 10 and contact the arc extinguishing grid 12, and cooperates with the composite movement of the moving frame 904 to realize impurity cleaning. When cleaning is not required, the silicone plate 111 retracts into the cleaning plate 10 to avoid affecting the normal operation of the arc extinguishing grid 12.

[0037] As a further embodiment of the present invention, a third spring 115 is provided between every two silicone plates 111 , and the cleaning plate 10 is provided with a cavity for slidingly cooperating with the push block 113 and the connecting frame 114 .

[0038] In a specific implementation, the third spring 115 between every two silicone plates 111 is stretched and energy is stored when the push block 113 pushes the inclined block 112 through the inclined surface to make the silicone plate 111 extend out of the cleaning plate 10. When the electric push rod drives the push block 113 to reset and disengage from the inclined block 112, the third spring 115 releases its elastic potential energy to push the silicone plate 111 to slide in the opposite direction and retract into the cavity of the cleaning plate 10, thereby realizing automatic reset of the silicone plate 111. At the same time, the cavity opened in the cleaning plate 10 provides guidance and space for the sliding of the push block 113 and the connecting frame 114.

[0039] Working principle: When using the dual-redundant drive type adaptive dual-speed circuit breaker, the touch plate 2 is separated from the contact through the operating handle, and the motor is started. The second bevel gear 8 is driven by the motor to rotate, and the rotation of the second bevel gear 8 drives the first bevel gear 7 engaged with it to rotate. The rotation of the first bevel gear 7 drives the screw rod 6 fixedly connected to one side to rotate, and the rotation of the screw rod 6 drives the sliding column 5 sleeved on its outer wall to move (the sliding column 5 is connected to the main body 1 through a limiter). The movement of the sliding column 5 drives the base 402 slidably connected to its inner wall to move synchronously. The movement of the base 402 drives the positioning column 401 fixedly connected to one side to move into the cavity opened by the connector 3. When When the positioning column 401 is fully engaged with the connecting member 3, the sliding column 5 continues to move, driving the sliding rod 406 inside it to slide in the cavity opened by the connecting column 405. At this time, the second spring 407 between the sliding column 5 and the base 402 is in a compressed state. The sliding column 5 drives the lock buckle 404 to rotate through the inclined surface opened by it. At this time, the first spring 403 between the base 402 and the lock buckle 404 is in a compressed state. After the lock buckle 404 rotates, it is locked with the protruding position of the connecting member 3, thereby locking the position of the touch plate 2 in the disengaged state, preventing the staff from accidentally touching the handle and causing the touch plate 2 to contact the contact point again, which may cause safety hazards. When the touch panel 2 needs to be unlocked, the sliding post 5 moves, driving the sliding rod 406 inside it to move, and then the sliding rod 406 drives the connecting post 405 and the base 402 to move. At this time, the inclined surface of the sliding post 5 is out of contact with the lock catch 404, and the compressed first spring 403 releases its elastic potential energy to drive the lock catch 404 to rotate, thereby unlocking the connecting member 3. When the second bevel gear 8 rotates, it drives the threaded rod 901 at its top to rotate, and the rotation of the threaded rod 901 drives the lifting column 902 mounted on its outer wall to move, thereby driving the fixed plate 903 fixed to the top of the lifting column 902 to move, and the movement of the fixed plate 903 drives the moving frame 904 to move synchronously. Since the connecting shaft 905 fixedly connected to one side of the moving frame 904 is slidably connected to the limit plate 906, and the slide groove 907 provided on the limit plate 906 is wavy, the moving frame 904 is driven to move in the vertical direction and the horizontal direction at the same time, so that when the moving frame 904 moves, the cleaning plate 10 and the silicone plate 111 fixed on one side thereof perform a composite motion in the vertical and horizontal directions between the two arc extinguishing grids 12, thereby enhancing the cleaning effect of the arc extinguishing grids 12; When the movable frame 904 rises between the two arc extinguishing grids 12, the silicone plate 111 is located inside the cleaning plate 10, and the silicone plate 111 and the cleaning plate 10 do not contact the arc extinguishing grid 12. Because an arc is generated at the moment when the contact plate 2 is separated from the contact, the arc needs to be eliminated by the arc extinguishing grid 12. At this time, the rising silicone plate 111 is located inside the cleaning plate 10 and does not hinder the operation of the arc extinguishing grid 12. When the lock of the connector 3 is released, the contact plate 2 contacts the contact and no arc is generated. At this time, the connecting frame 114 is driven to move by the electric push rod, and the movement of the connecting frame 114 drives the push block 113 to move. The inclined surface of the push block 113 makes the two inclined blocks 112 moves in both directions, thereby driving the two silicone plates 111 connected to the inclined block 112 to slide in both directions in the cleaning plate 10, causing the silicone plates 111 to contact the arc extinguishing grid 12, and the movable frame 904 moves downward to drive the silicone plates 111 to clean the arc extinguishing grid 12 for impurities. At this time, the scraped impurities slide to the top of the collecting plate 14 through the inclined plate of the connecting plate 13. The staff collects and processes the impurities by pulling out the collecting plate 14. When the silicone plate 111 moves to the bottom of the arc extinguishing grid 12, the push block 113 is moved by the electric push rod, so that the push block 113 is out of contact with the inclined block 112. At this time, the silicone plate 111 is reset by the third spring 115.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
