However, these circuit breakers typically lack lightning protection. During thunderstorms, high-voltage lightning can easily damage them, affecting not only the circuit breaker's integrity but also the normal operation of the entire circuit, leading to safety hazards and poor operational stability.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-5 As shown, a pole-mounted circuit breaker with a lightning protection mechanism includes a circuit breaker body 1, an insulating support 2 mounted on the circuit breaker body 1, an upper terminal block 3 and a lower terminal block 4 on the insulating support 2, a bracket 7 at the lower end of the circuit breaker body 1, and a column 6 connected to the end of the bracket 7. A lightning protection mechanism 5 is fixedly mounted on the circuit breaker body 1, and one end of the lightning protection mechanism 5 is connected to the column 6. A switch 8 is provided on the circuit breaker body 1, and a pointer 9 is provided on the circuit breaker body 1 near the switch 8.

[0020] When installing the pole-mounted circuit breaker, the bracket 7 is set on the column 6, and the circuit breaker body 1 is installed on the bracket 7. Wiring is done using the upper terminal 3 and lower terminal 4 on the insulating support 2, connecting the pole-mounted circuit breaker to the circuit. Then, the lightning protection mechanism 5, specifically the lightning-catching part, is installed on the circuit breaker body 1. The upper end of the conductive part is connected to the lightning-catching part, and the lower end is connected to the ground, thus providing lightning protection. When using the circuit breaker body 1, the current status of the circuit breaker can be checked according to the pointer 9. It can be manually opened and closed using the open / close switch 8. Under normal use, when a circuit fault occurs, the circuit breaker disconnects the circuit, providing protection. During thunderstorms, the lightning protection mechanism 5 provides lightning protection, preventing damage to the circuit breaker from high-voltage lightning and ensuring its effectiveness.

[0021] According to the above implementation scheme, the lightning protection mechanism 5 includes a shielding cover 501, a connecting seat 502, a lightning rod 503, a conductor 504, and a grounding rod 505. The shielding cover 501 is fixed to the circuit breaker body 1 with screws. The connecting seat 502 is fixedly connected to the lightning rod 503 and is mounted on the shielding cover 501. The upper end of the conductor 504 is connected to the connecting seat 502, and the lower end of the conductor 504 is connected to the grounding rod 505. The lightning protection mechanism 5 also includes a first connecting sleeve 506, a second connecting sleeve 507, a clamping assembly 508, a fixed rod 509, and a movable rod 510. The first connecting sleeve 506 and the second connecting sleeve 507 are connected to the column 6. The fixed rod 509 is fixed to the shielding cover 501. The movable rod 510 is connected to the second connecting sleeve 507. The clamping assembly 508 is located inside the movable rod 510.

[0022] When installing the lightning protection mechanism 5, the lower end of the shield 501 is connected to the circuit breaker body 1 by screws. The position of the movable rod 510 is adjusted according to the distance between the shield 501 and the column 6, so that the second connecting sleeve 507 abuts against the column 6. The movable rod 510 and the fixed rod 509 are fixed by tightening screws. Then, the first connecting sleeve 506 and the second connecting sleeve 507 are fixed together by bolts and nuts, thus forming an auxiliary support and improving the stability of the shield 501. After the shield 501 is fixed, the connecting seat 502 with the lightning rod 503 is placed on the shield 501. The upper end of the conductor 504 is connected to the connecting seat 502, and the lower end is connected to the grounding rod 505. Simultaneously, the part of the conductor 504 near the connecting seat 502 is further fixed by the clamping assembly 508. The grounding rod 505 is then inserted into the ground for use.

[0023] During the use of the lightning protection mechanism 5, when encountering thunderstorms, the shield 501 plays a role in lightning and rain protection, and the lightning rod 503 of the lightning receiving part plays a role in attracting lightning, which can guide the high voltage current to the conductor 504, and finally release it into the ground through the grounding rod 505, thus achieving the role of lightning protection.

[0024] The clamping assembly 508 includes a connecting rod 5081, a U-shaped groove 5082, a connecting block 5083, and an elastic clamping piece 5084. The U-shaped groove 5082 is formed on the connecting rod 5081. The connecting block 5083 and the elastic clamping piece 5084 are connected, and the connecting block 5083 is fixed on the connecting rod 5081.

[0025] When installing the wire 504, simply place the wire 504 into the U-shaped groove 5082 on the connecting rod 5081. The elastic clip 5084 on the connecting block 5083 provides elastic clamping for the wire 504, ensuring its stability. Then it can be used.

[0026] It should be noted that the lightning protection mechanism 5 effectively protects the pole-mounted circuit breaker during use, ensuring its effective operation even during thunderstorms and preventing damage from high-voltage lightning. The shielding cover 501 provides lightning protection and also offers some rain protection to the main body of the pole-mounted circuit breaker. The first connecting sleeve 506, the second connecting sleeve 507, the fixed rod 509, and the movable rod 510 connect to the upper end of the column 6, providing auxiliary support for the shielding cover 501 and increasing its stability. The clamping component 508 inside the movable rod 510 provides auxiliary clamping for the conductor 504, enhancing its stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
