Description

Technical Field

[0001] The utility model relates to an outdoor circuit breaker. Background Art

[0002] An outdoor circuit breaker is an important switching device used in an outdoor power system. Its main function is to disconnect and close an electric circuit to protect the power system and equipment from faults such as overload and short circuit. The outdoor circuit breaker plays a key role in power supply reliability and safety and is widely used in substations, distribution systems, transmission lines and other places. The outdoor circuit breaker includes an outdoor circuit breaker base. In order to facilitate movement and transportation, base handles are welded at both ends of the outdoor circuit breaker base. The existing base handles all adopt a non-detachable connection method with the base. Due to improper design of some base handles, when the outdoor circuit breaker is moved and installed, it will interfere with the operation of the internal mechanism. Some base handles are too simple in structure, resulting in defects. When customers carry them by hand, it is easy to cause bumps and injuries. Therefore, the existing outdoor circuit breaker is improved and optimized. Content of the Utility Model

[0003] To solve the above problems, the technical problem to be solved by the utility model is to provide an outdoor circuit breaker.

[0004] The technical solution adopted by the outdoor circuit breaker of the utility model is characterized in that it includes a circuit breaker base, base fixing screws and base handles detachably arranged at both ends of the circuit breaker base. The base handle includes a handle holding part. One side of the handle holding part is provided with a handle extension part and a handle docking part. A handle drainage groove is formed between the handle extension part and the handle docking part. A handle holding cavity is arranged in the handle holding part. A handle anti-movement column is arranged in the handle holding cavity. A handle elastic hook is arranged on the other side of the handle holding part;

[0005] The lower parts of the left and right sides of the circuit breaker base are bent outwards to form base installation parts. Waist-shaped fixing holes for installing the base fixing screws are arranged on the base installation parts. A base main cavity is arranged in the circuit breaker base. A base insertion interface is arranged on the side wall of the base main cavity. The handle docking part is inserted into the base insertion interface and its upper end abuts against the upper wall of the base main cavity. Handle bayonets corresponding to the handle elastic hooks are arranged on the left and right sides of the circuit breaker base near the base installation parts. Base installation part docking holes corresponding to the handle anti-movement column are arranged on the base installation parts.

[0006] Handle limit protrusions are further arranged at both ends of the handle extension part of the handle holding part. Base limit notches corresponding to the handle limit protrusions are arranged at both ends of the base insertion interface on the left and right sides of the circuit breaker base.

[0007] The upper surface of the handle holding part is an inclined plane, and the height of the handle holding part on the side close to the handle drain groove is lower than the height of the handle holding part on the side far from the handle drain groove.

[0008] A base inner baffle for limiting the insertion of the handle insertion part is provided at the base main body cavity near the base insertion interface.

[0009] The base handle is made of transparent material.

[0010] The advantages of the outdoor circuit breaker of the present utility model are as follows: The base handle is detachably designed, which will not interfere with the internal structure and is more flexible to use. After the transportation and fixation are completed, it is turned around and covered outside the base fixing screw to form a protective cover, avoiding the exposure of the base fixing screw resulting in rust and accidental disassembly, and greatly improving the protection and waterproof performance.

[0017] As Figures 1-5As shown in the figure, the outdoor circuit breaker of the present utility model includes a circuit breaker base 1, base fixing screws 2, and base handles 3 detachably provided at both ends of the circuit breaker base 1. The base handle 3 includes a handle holding part 5. On one side of the handle holding part 5, there is a handle extension part 6 and a handle docking part 7. A handle drainage groove 8 is formed between the handle extension part 6 and the handle docking part 7. Inside the handle holding part 5, there is a handle holding cavity 9. Inside the handle holding cavity 9, there is a handle anti-movement post 16. On the other side of the handle holding part 5, there is a handle elastic hook 17. The lower parts of the left and right sides of the circuit breaker base 1 are bent outward to form base mounting parts 11. On the base mounting parts 11, there are kidney-shaped fixing holes 12 for installing the base fixing screws 2. Inside the circuit breaker base 1, there is a base main cavity 13. On the side wall of the base main cavity 13, there is a base insertion interface 14. The handle docking part 7 is inserted into the base insertion interface 14 and its upper end abuts against the upper wall of the base main cavity 13. On the left and right sides of the circuit breaker base 1 near the base mounting parts 11, there are handle bayonets 19 corresponding to the handle elastic hooks 17. On the base mounting parts 11, there are base mounting part docking holes 18 corresponding to the handle anti-movement posts 16. The base handle 3 is designed to be detachable, which will not interfere with the internal structure and is more flexible to use. When the transportation and fixing are completed, it is turned around and covered outside the base fixing screws 2 to form a protective cover, avoiding the exposure of the base fixing screws 2 resulting in rust and accidental disassembly, and greatly improving the protection and waterproof performance.

[0018] On both ends of the handle extension part 6 of the handle holding part 5, there are also handle limit protrusions 21. On the left and right sides of the circuit breaker base 1, at both ends of the base insertion interface 14, there are base limit notches 22 docked with the handle limit protrusions 21. After the handle docking part 7 is docked with the circuit breaker base 1, it can effectively prevent the swing of the base handle 3 and improve the stability and reliability after installation.

[0019] The upper surface of the handle holding part 5 is an inclined plane. The height of the side of the handle holding part 5 close to the handle drainage groove 8 is lower than the height of the side of the handle holding part 5 far from the handle drainage groove 8, so that rainwater can quickly drain through the handle drainage groove 8.

[0020] Near the base insertion interface 14 of the base main cavity 13, there is a base inner baffle 23 for limiting the insertion of the handle docking part 7, further improving the stability and safety after the docking of the base handle 3 and preventing the base handle 3 from falling off easily.

[0021] The base handle 3 is made of transparent material, which is not only beautiful but also can provide an additional visual inspection function.

[0022] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model are all included in the protection scope of the present utility model.
