Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to an outdoor integrated primary and secondary circuit breaker with built-in isolation and a viewing window. Background Technology

[0002] A circuit breaker is a mechanical switching device that can close, carry, and interrupt normal circuit current, and close the current under overcurrent and abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When they experience serious overload, short circuit, or undervoltage faults, they can automatically disconnect the circuit. Their function is equivalent to a combination of a fuse switch and an over / under-temperature relay, and generally no parts need to be replaced after interrupting the fault current.

[0003] In existing technologies, circuit breakers have external isolating switches, which are exposed to the external environment and are susceptible to dust, moisture, corrosive gases, and other factors. These factors gradually erode the surface of the isolating switch, leading to a decrease in its insulation performance. The exposed isolating switch makes it easy for operators to directly contact live parts during operation, increasing the risk of electric shock and potentially causing accidents. The exposed isolating switch also makes maintenance more complex and difficult, requiring operators to regularly clean, inspect, and repair it to ensure its normal operation, thus increasing the workload of staff. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an outdoor integrated primary and secondary circuit breaker with built-in isolation and a viewing window, which solves the problems of external isolating switches being susceptible to environmental corrosion, having low operational safety, high failure rate, and increased maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an outdoor integrated circuit breaker with built-in isolation and viewing window, comprising a housing base, three integrated poles on the top of the housing base, a circuit breaker connecting shaft and a disconnecting switch connecting shaft rotatably connected to the rear side of the housing base cavity, the circuit breaker connecting shaft being located above the disconnecting switch connecting shaft, three eccentric wheels corresponding to the integrated poles being fixedly connected to the surface of the circuit breaker connecting shaft, and a length adjustment shaft rotatably connected to the other end of the eccentric wheels; The top end of the length adjustment shaft is pulled out and extended to the rear side of the inner cavity of the integrated pole post, and is fixedly connected to an insulating pull rod. The vacuum interrupter inside the integrated pole post is provided with a moving contact that moves in the vertical direction. The bottom end of the moving contact is pulled out and extended to the inner cavity of the integrated pole post, and is fixedly connected to the top end of the insulating pull rod. The surface of the disconnecting switch connecting shaft is fixedly connected with three first disconnecting switch drive crank arms corresponding to the integrated pole post. The other end of the first disconnecting switch drive crank arm is rotatably connected with a second disconnecting switch drive crank arm. The other end of the second disconnecting switch drive crank arm is rotatably connected with a push adjustment shaft. The top end of the push adjustment shaft is pulled out and extended to the top end of the inner cavity of the integrated pole post, and is fixedly connected with a moving guide rod. The top of the moving guide rod is pulled out and extends into the isolating switch chamber inside the integrated pole. A sliding contact adapted to the moving guide rod is fixedly connected to the top of the inner wall of the integrated pole. The moving contact and the sliding contact are electrically connected by a flexible connection. When closing, the isolating switch connecting shaft rotates in advance to close the isolating switch, and the circuit breaker connecting shaft rotates subsequently to close the circuit breaker. When opening, the circuit breaker connecting shaft resets in advance to open the circuit breaker, and then the isolating switch connecting shaft resets to open the isolating switch.

[0006] Furthermore, three circuit breaker stationary contacts corresponding to the moving contact are fixedly connected to the rear side of the top of the integrated pole post, and the top of the circuit breaker stationary contacts extends into the vacuum interrupter chamber inside the integrated pole post.

[0007] Furthermore, the top of the front side of the integrated pole post is provided with three copper rods corresponding to the moving guide rod, and the top of the inner wall of the isolation switch chamber inside the integrated pole post is fixedly connected to an output end located above the moving guide rod, and the output end is electrically connected to the corresponding copper rod.

[0008] Furthermore, a spiral spring mechanism is provided at one end of the inner cavity of the receiving seat. The two output shafts of the spiral spring mechanism are respectively fixedly connected to the circuit breaker connecting shaft and the disconnecting switch connecting shaft. The input shaft of the spiral spring mechanism extends rotatably to the outside of the receiving seat and is fixedly connected to an energy storage handle. A coil spring energy storage indicator is provided on the receiving seat.

[0009] Furthermore, a circuit breaker open / close position indicator is provided on one end face of the receiving base, a disconnector switch open / close position indicator is provided on one end face of the receiving base, and a manual opening / closing handle is provided on one end face of the receiving base.

[0010] Furthermore, the surface of the integrated pole is provided with a protruding viewing window adapted to its circuit breaker, and a labyrinth-type rubber seal is provided between the protruding viewing window and the joint of the integrated pole.

[0011] Furthermore, mounting plates are fixedly connected to the bottom of both ends of the receiving seat, and mounting plates have mounting openings on their surfaces.

[0012] Furthermore, the protruding viewing window is made of UV-resistant rigid polycarbonate material, and the surface of the integrated pole is coated with a UV-resistant coating.

[0013] Furthermore, both ends of the top of the housing are fixedly connected to handles for carrying and transporting, and the surface of the handles is provided with anti-slip texture.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: The built-in isolating switch is completely encapsulated inside the circuit breaker, preventing operators from directly contacting live parts and fundamentally eliminating the risk of electric shock. It can be integrated with the circuit breaker's mechanical or electrical interlocking system, ensuring that the isolating switch cannot be operated when the circuit breaker is closed, avoiding accidents caused by opening or closing the switch under load. The built-in structure confines the electric arc inside the circuit breaker, where it is quickly extinguished by an arc-extinguishing device, preventing arc leakage and injury to operators. The fully enclosed structure effectively blocks dust, humid air, and corrosive gases from entering, extending the equipment's service life. It is particularly suitable for harsh industrial environments or outdoor applications. The built-in isolating switch is unaffected by external pollution, reducing faults caused by decreased insulation performance and improving system stability. The built-in design reduces external mechanical connection parts, lowering the probability of faults caused by loosening or wear. Maintenance does not require separate operation of the isolating switch, reducing maintenance steps and time, while also preventing secondary faults caused by misoperation. The enclosed environment protects the isolating switch from environmental corrosion, reducing maintenance frequency and extending the device's service life. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-3 The present invention provides a technical solution: an outdoor integrated circuit breaker with built-in isolation and viewing window, including a housing 24, three integrated poles 3 are provided on the top of the housing 24, a current transformer 11 is provided inside the integrated pole 3, and a circuit breaker connecting shaft 7 and a disconnecting switch connecting shaft 8 are rotatably connected to the rear side of the inner cavity of the housing 24.

[0019] The circuit breaker connecting shaft 7 is located above the disconnecting switch connecting shaft 8. Three eccentric wheels 27 corresponding to the integrated pole post 3 are fixedly connected to the surface of the circuit breaker connecting shaft 7. The other end of the eccentric wheel 27 is rotatably connected to the length adjusting shaft 6.

[0020] The top end of the length adjustment shaft 6 is pulled out and extended to the rear side of the inner cavity of the integrated pole post 3, and is fixedly connected to the insulating pull rod 5. The vacuum interrupter inside the integrated pole post 3 is provided with a moving contact 2 that moves in the vertical direction. The bottom end of the moving contact 2 is pulled out and extended to the inner cavity of the integrated pole post 3, and is fixedly connected to the top end of the insulating pull rod 5.

[0021] Three first disconnect switch drive crank arms 17 corresponding to the integrated pole post 3 are fixedly connected to the surface of the disconnect switch connecting shaft 8. The other end of the first disconnect switch drive crank arm 17 is rotatably connected to the second disconnect switch drive crank arm 18. The other end of the second disconnect switch drive crank arm 18 is rotatably connected to the push adjustment shaft 16. The top end of the push adjustment shaft 16 is pulled out and extended to the top end of the inner cavity of the integrated pole post 3, and is fixedly connected to the moving guide rod 12.

[0022] The top of the moving guide rod 12 is pulled out and extended into the isolation switch chamber inside the integrated pole post 3. The top of the inner wall of the integrated pole post 3 is fixedly connected to a sliding contact 13 that is adapted to the moving guide rod 12. The moving contact 2 and the sliding contact 13 are electrically connected through a flexible connection 4.

[0023] When closing, the disconnector switch connecting shaft 8 rotates in advance to close the disconnector switch, and then the circuit breaker connecting shaft 7 rotates to close the circuit breaker. When opening, the circuit breaker connecting shaft 7 is reset in advance to open the circuit breaker, and then the disconnector switch connecting shaft 8 is reset to open the disconnector switch.

[0024] With its built-in isolating switch completely enclosed inside the circuit breaker, operators cannot directly contact live parts, fundamentally eliminating the risk of electric shock. It can be integrated with the circuit breaker's mechanical or electrical interlocking system to ensure that the isolating switch cannot be operated when the circuit breaker is closed, thus avoiding accidents caused by opening or closing the switch under load.

[0025] The built-in structure confines the electric arc inside the circuit breaker and extinguishes it quickly through the arc-extinguishing device, preventing the arc from leaking out and causing injury to the operator. The fully enclosed structure effectively blocks dust, humid air and corrosive gases from entering, extending the service life of the equipment. It is especially suitable for harsh industrial environments or outdoor applications. The built-in isolating switch is not affected by external pollution, reducing faults caused by decreased insulation performance and improving system stability.

[0026] The built-in design reduces external mechanical connection parts, lowering the probability of failure due to loosening or wear. Maintenance does not require separate operation of the isolating switch, reducing maintenance steps and time. It also avoids secondary failures caused by misoperation. The enclosed environment protects the isolating switch from environmental corrosion, reducing maintenance frequency and extending the service life of the device.

[0027] Three circuit breaker stationary contacts 1 corresponding to the moving contact 2 are fixedly connected to the rear side of the top of the integrated pole 3. The top of the circuit breaker stationary contact 1 extends into the vacuum interrupter chamber inside the corresponding integrated pole 3. After the moving contact 2 rises to contact the bottom end of the circuit breaker stationary contact 1, the circuit breaker can be closed. When the moving contact 2 is out of contact with the circuit breaker stationary contact 1, the circuit breaker is opened.

[0028] The top of the front side of the integrated pole post 3 is provided with three copper rods 10 corresponding to the moving guide rod 12. The top of the inner wall of the isolation switch chamber inside the integrated pole post 3 is fixedly connected to the output terminal 9 located above the moving guide rod 12. The output terminal 9 is electrically connected to the corresponding copper rod 10.

[0029] After the moving guide rod 12 rises to the position of contacting the output terminal 9, the isolating switch is closed. After the moving guide rod 12 falls to the position of disengaging from the output terminal 9, the isolating switch is opened.

[0030] A spiral spring mechanism 15 is provided at one end of the inner cavity of the receiving seat 24. The two output shafts of the spiral spring mechanism 15 are respectively fixedly connected to the circuit breaker connecting shaft 7 and the disconnecting switch connecting shaft 8. The input shaft of the spiral spring mechanism 15 extends to the outside of the receiving seat 24 and is fixedly connected to the energy storage handle 19. A coil spring energy storage indicator 21 is provided on the receiving seat 24.

[0031] By operating the energy storage handle 19, energy can be stored in the worm spring mechanism 15. After release, it can drive the disconnector connection shaft 8 to rotate in advance. During the rotation of the disconnector connection shaft 8, the tilt angle can be changed through the first disconnector drive crank arm 17 and the second disconnector drive crank arm 18. In conjunction with the connection of the push adjustment shaft 16 and the push shaft 14, the moving guide rod 12 is driven to rise to contact the output end 9, so that the disconnector switch is closed. The circuit breaker connection shaft 7 is then driven to rotate by another output shaft of the worm spring mechanism 15. After the tilt angle is changed through the eccentric wheel 27, the moving contact 2 is lifted to contact the stationary contact 1 of the circuit breaker through the connection of the length adjustment shaft 6 and the insulating pull rod 5, so that the circuit breaker is closed. The flow channel is completed by the connection of the flexible connection 4 and the sliding contact 13. After the disconnector switch is closed, the circuit breaker is closed again.

[0032] The energy storage handle 19 is operated again to store energy in the worm spring mechanism 15. When the circuit breaker is opened after release, the circuit breaker connecting shaft 7 is pre-reset. Then, through the connection between the length adjusting shaft 6 and the insulating pull rod 5, the moving contact 2 can be pulled down, and the moving contact 2 is disengaged from the stationary contact 1 of the circuit breaker, so that the circuit breaker is opened. Next, the disconnecting switch connecting shaft 8 is driven to rotate and reset by another output shaft of the worm spring mechanism 15. With the reset of the first disconnecting switch drive crank arm 17 and the second disconnecting switch drive crank arm 18, the moving guide rod 12 is driven down by pushing the connection between the adjusting shaft 16 and the push shaft 14, disengaging from the contact state with the output end 9, so that the disconnecting switch is opened. After the circuit breaker is opened, the disconnecting switch is opened again.

[0033] The worm coil spring mechanism 15 completes spring winding energy storage only through the manual energy storage handle or the electric energy storage motor interface. The two output shafts of the mechanism can achieve independent power transmission of the two components through the spring preload. It also integrates a mechanical interlocking cam. When closing, the isolating switch drive shaft moves first, and the circuit breaker drive shaft starts only after the interlocking contact is triggered. When opening, the circuit breaker drive shaft resets first, and the isolating switch drive shaft resets later, strictly following the logic of "closing the isolating switch first and then closing the circuit breaker, and breaking the circuit breaker first and then breaking the isolating switch".

[0034] A circuit breaker open / close position indicator 20 is provided on one end face of the housing 24, a disconnector open / close position indicator 23 is provided on one end face of the housing 24, and a manual open / close handle 22 is provided on one end face of the housing 24.

[0035] The surface of the integrated pole post 3 is provided with a protruding viewing window 25 adapted to its circuit breaker, and a labyrinth rubber seal 26 is provided between the protruding viewing window 25 and the joint of the integrated pole post 3.

[0036] The integrated isolation labyrinth rubber seal 26 and mechanical position indicator status mark, the protruding viewing window 25 are used to visually view the break status, the mechanical indicator shows the opening and closing position through red and green marks, the window structure adopts a protruding structure and uses a labyrinth sealing design, with silicone rubber sealing ring, and stainless steel fasteners to connect the protruding viewing window 25, effectively preventing condensation and corrosive media from entering.

[0037] Mounting plates are fixedly connected to the bottom of both ends of the receiving seat 24, and mounting holes are opened on the surface of the mounting plates.

[0038] The protruding viewing window 25 is made of UV-resistant rigid polycarbonate material, and the surface of the integrated pole 3 is coated with a UV-resistant coating.

[0039] The UV-resistant coating has excellent light transmittance, allowing both visible light transmittance (≥92%) and infrared light transmittance (≥85%) to pass through simultaneously. This allows maintenance personnel to directly observe the isolation break with the naked eye or remotely monitor the contact temperature using an infrared thermometer. With an IP66 protection rating, it has passed waterproof, dustproof, and impact resistance tests, and can withstand outdoor rainstorms, sandstorms, and mechanical collisions, exhibiting strong weather resistance.

[0040] Both ends of the top of the housing 24 are fixedly connected to handles for carrying and transporting, and the surface of the handles is provided with anti-slip texture.

[0041] The isolating switch and the circuit breaker body are configured with a natural mechanical interlocking mechanism to realize the operation logic of "break first, then open; close first, then connect": the isolating switch can only be opened after the circuit breaker is fully opened; the circuit breaker can only be operated after the isolating switch is fully closed or opened, thus completely eliminating the risk of misoperation of opening and closing the isolating switch under load.

[0042] With a compact structure and superior size and weight, the worm coil spring mechanism 15 adopts a "winding energy storage" design. The spring body is integrated into the mechanism in a disc shape, eliminating the need for the long stroke space of traditional tension / compression springs. It has fewer structural parts and a shorter transmission chain, which fundamentally reduces the risk of failure caused by a large number of parts and complex transmission.

[0043] The energy storage operation is simple and the state is stable. The energy storage method of the worm coil spring mechanism 15 is more flexible, and the state is stable for a long time after energy storage. There is no need for frequent inspection or energy replenishment. It supports two modes of manual energy storage: manual operation via crank and electric energy storage motor drive.

[0044] With reliable operation and long mechanical life, the worm coil spring mechanism 15 has stable force output characteristics and no obvious impact during the movement of the mechanism, which can effectively improve the overall reliability and life. The spring force changes linearly with the winding angle, and the force output is uniform during the opening and closing process, avoiding the vibration of the mechanism or wear of parts caused by the "force change" of the helical spring. The opening and closing time has high stability and small deviation.

[0045] With high energy utilization efficiency and adaptability to multiple scenarios, the spiral spring mechanism 15 has low energy transmission loss and can flexibly adapt to circuit breakers with different breaking requirements. The stored energy can be converted into opening and closing operating force more efficiently. It can adapt to circuit breakers with different breaking currents of 25kA-40kA and has strong versatility.

[0046] During operation, the energy storage handle 19 stores energy in the worm spring mechanism 15. After release, it drives the disconnector connection shaft 8 to rotate pre-rotate. During rotation, the disconnector connection shaft 8 changes its tilt angle via the first disconnector drive crank arm 17 and the second disconnector drive crank arm 18, and in conjunction with the connection between the adjusting shaft 16 and the push shaft 14, it drives the moving guide rod 12 to rise to contact the output end 9, thus closing the disconnector switch. The circuit breaker connection shaft 7 is then driven to rotate by another output shaft of the worm spring mechanism 15. After changing its tilt angle via the eccentric wheel 27, it lifts the moving contact 2 to contact the stationary contact 1 of the circuit breaker via the connection between the length adjusting shaft 6 and the insulating pull rod 5, thus closing the circuit breaker. The circuit breaker is then closed by utilizing the connection between the flexible connection 4 and the sliding contact 13. The circuit breaker forms a flow channel, and after the isolating switch is closed, the circuit breaker is closed again. The energy storage handle 19 is operated again to store energy in the worm spring mechanism 15. When the circuit breaker is opened after release, the circuit breaker connecting shaft 7 is pre-reset. Then, through the connection of the length adjustment shaft 6 and the insulating pull rod 5, the moving contact 2 can be pulled down. The moving contact 2 is disengaged from the stationary contact 1 of the circuit breaker, so that the circuit breaker is opened. Next, the isolating switch connecting shaft 8 is driven to rotate and reset by another output shaft of the worm spring mechanism 15. With the reset of the first isolating switch drive crank arm 17 and the second isolating switch drive crank arm 18, the moving guide rod 12 is driven down by the connection of the adjustment shaft 16 and the push shaft 14, and is disengaged from the contact state with the output end 9, so that the isolating switch is opened. After the circuit breaker is opened, the isolating switch is opened again.
