Description

Technical Field

[0001] The utility model relates to the field of pole-mounted circuit breakers, in particular to an integrated sealed primary-secondary fusion pole-mounted circuit breaker. Background Art

[0002] With the advancement of intelligent upgrades in distribution networks, integrated sealed primary and secondary fusion pole-mounted circuit breakers have been widely used in power systems due to their integrated design and high reliability. Traditional primary and secondary fusion pole-mounted circuit breakers integrate the primary high-voltage switch and the secondary intelligent terminal in the electrical box, with measurement, protection, communication and other functions, and can adapt to complex outdoor environments. However, in actual operation, the electronic components inside the electrical box are affected by factors such as current load, ambient temperature and humidity for a long time, and are prone to failures due to local overheating. In the prior art, temperature monitoring mostly relies on built-in sensors or external fixed temperature measuring devices: the built-in solution requires opening holes in the sealing structure of the electrical box for lead-in, which may damage the protection level and is troublesome to replace; the external solution usually uses a screw-fixed structure, which requires special tools for installation and maintenance, and is cumbersome and inefficient to disassemble, making it difficult to meet the needs of frequent maintenance or sensor upgrades.
