[0003] The most commonly used is an external independent voltage transformer. The voltage transformer of this solution is installed independently and needs to be configured with a separate mounting bracket. It is not convenient for on-site installation and undoubtedly increases the workload of the installer.
[0004] The deep fusion pole-mounted circuit breaker with the power-taking capacitor built into the pole is a device that is cast into the solid-sealed pole. It has the following defects: casting the capacitor power-taking device into the solid-sealed pole is difficult to process, costly, and has a high product defect rate; the solid-sealed pole is large in size and weight, which is not convenient for assembly and installation of the whole machine; the capacitor power-taking device generates a lot of heat when working, and is easily burned by high temperature when placed in a confined space, affecting the safety of the line and the reliability of power supply.
[0005] The integrated design pole-mounted circuit breaker in which the external capacitor power supply device is fixed on the pole-mounted circuit breaker housing has the capacitor power supply device installed at both ends of the top of the mechanism box or in the middle of the three sealed poles. An inspection port is required on the back of the mechanism box, and when the capacitor power supply device is damaged and replaced, the entire mechanism box and the internal operating mechanism need to be opened, and on-site maintenance and replacement are relatively difficult.
