Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit breaker technology, specifically a frame-type intelligent circuit breaker. Background Technology
[0002] In power systems, circuit breakers, as critical electrical protection devices, bear the important responsibility of interrupting current and protecting circuits and equipment when faults such as overloads and short circuits occur. Traditional circuit breakers typically employ an integral structural design with strong sealing to ensure stable operation in harsh electrical environments. However, this integral structure also brings some problems that cannot be ignored.
[0003] First, due to the highly sealed structure of circuit breakers, maintenance or disassembly procedures are often cumbersome. Maintenance personnel need to spend considerable time and effort disassembling the circuit breaker, which not only reduces work efficiency but may also damage the equipment due to improper operation. Furthermore, the highly sealed structure makes it difficult to perform a thorough cleaning and inspection of the circuit breaker's interior during maintenance, thus affecting the equipment's reliability and service life.
[0004] Secondly, a large amount of heat is generated inside the circuit breaker during operation. If it cannot be dissipated in a timely and effective manner, the equipment temperature may rise, which may affect its normal operation. Due to structural limitations, traditional circuit breakers often cannot achieve good heat dissipation while ensuring sealing. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figure 1-5 This utility model provides a frame-type intelligent circuit breaker, including a circuit breaker body 1, a frame-type outer shell 2 movably connected to the bottom of the circuit breaker body 1, two connecting components for quick disassembly of the circuit breaker body 1 provided on the top of the frame-type outer shell 2, and a connecting plate 12 fixedly connected to both sides of the frame-type outer shell 2, a mounting plate 10 fixedly connected to one end of each of the two connecting plates 12, a first locking plate 13 fixedly connected to both sides of each of the two mounting plates 10, and a bolt 15 movably connected to one end of each of the two mounting plates 10, and a nut 16 threadedly connected to one end of each of the two bolts 15.
[0026] Furthermore, a set of heat dissipation holes 8 are provided on both sides of the frame-type outer shell 2, and two sets of heat dissipation slots are provided below the two sets of heat dissipation holes 8 on both sides of the frame-type outer shell 2. Multiple heat dissipation fins 9 are fixedly connected inside the two sets of heat dissipation slots, and a sliding groove 7 is provided on the inner wall of both sides of the frame-type outer shell 2.
[0027] Furthermore, both connecting components include a fixing plate 3, a limiting screw 4, a nut 5, and a slider 6. A fixing plate 3 is fixedly connected to both sides of the circuit breaker body 1, and a slider 6 is fixedly connected to the bottom of each of the two fixing plates 3 on both sides of the circuit breaker body 1. A set of limiting screws 4 is fixedly connected to the top of both sides of the frame housing 2, and a set of nuts 5 is threadedly connected to the top of each of the two sets of limiting screws 4.
[0028] Furthermore, each of the two fixing plates 3 has a set of through holes at its top, and the tops of the two sets of limiting screws 4 are respectively threaded together with the two sets of nuts 5 through the two sets of through holes.
[0029] Furthermore, both sliders 6 are T-shaped, and the T-shaped ends of the two sliders 6 are slidably connected inside the two grooves 7 respectively.
[0030] Furthermore, both connecting plates 12 are U-shaped, and two second locking plates 14 are fixedly connected to the inner walls of both connecting plates 12. A groove is provided on one side of each connecting plate 12, and two nuts 16 are fixedly connected to the inside of the two grooves respectively.
[0031] Furthermore, each of the two mounting plates 10 has a mounting hole 11 at its top, and one end of each mounting plate 10 is movably connected to the inside of the U-shaped end of the two connecting plates 12, and one end of the bolt 15 passes through the connecting plate 12 and the mounting plate 10 and is threaded together with the nut 16.
[0032] Furthermore, one end of both the first positioning plate 13 and the second positioning plate 14 is toothed, and the toothed end of the first positioning plate 13 is movably connected to the toothed end of the second positioning plate 14.
[0033] In this embodiment of the application, when it is necessary to disassemble the circuit breaker body 1, firstly, by rotating the nut 5, the threaded connection between the nut 5 and the limiting screw 4 is used to unscrew the nut 5 from the limiting screw 4. Then, by lifting the circuit breaker body 1 upward, the circuit breaker body 1 moves the two fixing plates 3 upward, causing the limiting screw 4 to pass through the through hole on the fixing plate 3, thus disengaging the limiting screw 4 from the fixing plate 3, thereby detaching the circuit breaker body 1 from the frame-type housing 2, facilitating the disassembly of the circuit breaker body 1. Conversely, when it is necessary to install the circuit breaker body 1, firstly... Align the bottom ends of the two sliders 6 with the two grooves 7 on the inner wall of the frame housing 2, allowing the two sliders 6 to slide inside the grooves 7. This causes the circuit breaker body 1 to slide into the frame housing 2, preventing the circuit breaker body 1 from shifting downwards. Simultaneously, this aligns the top of the limiting screw 4 on the frame housing 2 with the through hole on the fixing plate 3. Then, the circuit breaker body 1 is installed inside the frame housing 2 using the nut 5. Ventilation and heat dissipation are achieved through the two sets of heat dissipation holes 8 on the frame housing 2, while the heat sink 9 ensures proper circuit breaker operation. The heat from the circuit breaker body 1 is transferred to the heat sink 9 through the frame-type outer shell 2, and then transferred to the outside of the frame-type outer shell 2 through the heat sink 9, thereby further dissipating heat from the circuit breaker body 1 and preventing the components on the circuit breaker body 1 from burning out. Then, by rotating the mounting plate 10, one end of the mounting plate 10 can move around the bolt 15 in a circular motion, thereby folding the mounting plate 10. This reduces the transportation space and the risk of damage or deformation to the mounting plate 10 due to shaking or collision, thus reducing the hassle of subsequent installation. When installation is required, simply pry the mounting plate 10 so that it folds into place with the frame-type outer shell. 2. Form an L-shape, and then rotate the bolt 15. Utilize the threaded connection between the bolt 15 and nut 16 to press the U-shaped sides of the connecting plate 12. Utilizing the elasticity of the connecting plate 12, the connecting plate 12 drives the two second locking plates 14 to move closer to the two first locking plates 13 on both sides of the mounting plate 10. This causes the toothed ends of the second locking plates 14 to engage with the toothed ends of the first locking plates 13, preventing the mounting plate 10 from rotating and thus fixing it in place. Then, the circuit breaker is installed in a suitable location through the mounting holes 11 on the mounting plate 10.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
