Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breakers, and in particular to a quick-installation insulating protective cover for pole-mounted circuit breakers. Background Technology

[0002] As a key high-voltage electrical device for controlling and protecting the power distribution network in outdoor power distribution systems, pole-mounted circuit breakers are of paramount importance in terms of operational stability and safety. With the continuous development of urban construction, power distribution line user units are becoming increasingly concentrated, and the requirements for the reliability of line operation quality and the demand for power distribution network automation construction are constantly increasing, leading to the increasingly widespread application of pole-mounted circuit breakers.

[0003] Existing problems

[0004] The installation process is complex: Traditional pole-mounted circuit breaker insulation protection covers often require complex manual operations during installation. For example, when installing the insulation cover, it is necessary to insert connecting nails into the holes on both sides of the cover opening to fix it. The operation is cumbersome, and when installing it under live conditions, it requires extremely high skills and safety assurance from the operators, which increases the difficulty and risk of installation.

[0005] Safety hazards: Some pole-mounted circuit breakers that have been installed have exposed metal at their terminals, making them susceptible to foreign objects and other contaminants, which could lead to tripping and power outages, affecting the stability and reliability of the power supply.

[0006] Uninterrupted installation is not possible: In actual power grid operation, installing insulating protective covers during power outages will affect users' normal power supply. Existing insulating protective covers are difficult to meet the requirements of uninterrupted installation, which limits their application scope and effectiveness.

[0007] Furthermore, when the protective cover is used on the components of the pole-mounted circuit breaker, a fault in the component of the pole-mounted circuit breaker will cause a sudden increase in temperature. After the temperature rises suddenly, it is impossible to accurately locate the faulty component of the pole-mounted circuit breaker.

[0008] Therefore, it is necessary to provide a quick-installation pole-mounted circuit breaker insulation protection cover to solve the above-mentioned technical problems. Utility Model Content
