[0025] The present invention will be further explained below in conjunction with specific implementation plans, but the present invention is not limited thereto.

[0026] Manual pole-mounted circuit breakers lead to product hazards due to the inability to determine their service life: manual pole-mounted circuit breakers are installed on user lines. Due to the accumulation of time after installation, it is impossible to record and determine the number of opening and closing times, resulting in an inability to determine their reliability and service life. Party A, such as the State Grid, also has clear requirements for the number of opening and closing times (the number of opening and closing times must reach more than 10,000 times), so the number of opening and closing times is an important technical and quality indicator. Because it is impossible to determine its quality and service life, serious electrical safety hazards arise, resulting in large-scale power outages, electric shocks and other property hazards to users.

[0027] The manual column circuit breaker provided in this embodiment not only has the over-current speed breaking protection function and the opening arc extinguishing protection function, but also has a counting function, which can intuitively reflect the service life of the product.

The manual opening and closing handle 5, the opening and closing indicator needle 9, and the opening / closing counting assembly are all mounted on the manual pole-mounted circuit breaker body. The manual pole-mounted circuit breaker body also has indicator marks for the "open" position and the "closed" position.

[0029] The manual opening and closing handle 5 is linked to the opening and closing indicator needle 9. By controlling the manual opening and closing handle 5, the tail end of the opening and closing indicator needle 9 dynamically corresponds to the indication mark "open" position and "closed" position;

[0030] The swing of the opening / closing indicator needle 9 is linked to the dynamic counting of the opening / closing counting component, and the opening / closing counting component is used to record the corresponding number of swings of the opening / closing indicator needle 9.

[0031] In this embodiment, the pole-mounted circuit breaker is in its natural state, with the opening / closing indicator needle 9 pointing to the "open" position. Pull the manual opening / closing handle downward until the opening / closing indicator needle 9 points from the "open" position to the "closed" position. At this point, the tip of the opening / closing indicator needle 9 touches the counting rod of the closing counter 12, the closing counter counts +1, and the closing counter records a closing action. Then, pull the left pull ring of the manual opening / closing handle 5 downward until the opening / closing indicator needle 9 points from the "closed" position to the "open" position. At this point, the tip of the opening / closing indicator needle 9 touches the counting rod of the opening counter 11, the opening counter counts +1, and the opening counter records a closing action.

[0032] Specifically, the manual opening and closing handle 5 and the opening and closing indicator needle 9 are linked by the following structure: pull ring structures are symmetrically provided at both ends of the manual opening and closing handle 5, including a left pull ring and a right pull ring; the middle part of the manual opening and closing handle 5 is connected to the transmission gear 14 with a limit slot by a screw; the head end of the opening and closing indicator needle 9 is connected to the opening and closing indicator scale wheel 16 by a screw; the transmission gear 14 with a limit slot is connected to the opening and closing indicator scale wheel 16 by a chain 13;
