[0002] A pole-mounted circuit breaker is a type of switchgear mounted on a utility pole. Its primary function is to automatically or manually control the power system to protect equipment and lines from overcurrent and short-circuit currents. Pole-mounted circuit breakers are widely used in a variety of applications, including power distribution networks, wind power generation, solar power generation, industrial power generation, and transmission lines.

[0003] Pole-mounted circuit breakers are installed and operated on utility poles. They are primarily used to interrupt and close load currents, overload currents, and short-circuit currents in power grids, ensuring safe and stable operation of the power system. Pole-mounted circuit breakers primarily consist of an operating mechanism, an arc extinguishing chamber, a current transformer, insulation components, and a control system.

[0004] In the prior art, pole-mounted circuit breakers are installed in various ways, including bench-mounted installation, hoisting installation, single-pole installation, and double-pole installation. During the installation process, most pole-mounted circuit breakers require hoisting the circuit breaker to the target location on the utility pole, and then using tools to securely connect the clamp of the circuit breaker to the utility pole. Furthermore, when installing on utility poles of different diameters, corresponding clamps must be selected. Furthermore, when replacing a different clamp with the same pole-mounted circuit breaker, the entire circuit breaker must be disassembled, and then a suitable clamp must be selected and installed on the circuit breaker before it is mounted on the utility pole. This entire installation process is cumbersome, time-consuming, and inefficient. Utility Model Content
