Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pole-mounted circuit breakers, and particularly relates to a pole-mounted circuit breaker with integrated design. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] With the development of power distribution automation technology, pole-mounted circuit breakers and feeder terminals play an increasingly important role in distribution networks. The pole-mounted circuit breaker and the feeder terminal are a kind of switching device in a medium-voltage power system installed on a power pole.

[0004] The pole-mounted circuit breaker not only needs to have efficient breaking capacity, but also needs to have good control and monitoring functions. However, the pole-mounted circuit breaker does not have intelligent capabilities and is generally used in combination with a feeder terminal to collect line data, execute protection logic, and respond to remote control commands, thereby realizing fault protection and removal functions of the medium-voltage power line. However, the existing pole-mounted circuit breaker and feeder terminal are two independent devices and have the following natural deficiencies.

[0005] Large space occupation: Traditional pole-mounted circuit breakers and feeder terminals usually need to be installed separately, occupying a large area in the limited space of the power pole.

[0006] Complex maintenance: Separate devices are generally products of two different manufacturers and need to be maintained and upgraded separately. Cooperation between them often causes problems, increasing operating costs and maintenance difficulty.

[0007] Communication interference: Due to the physical distance, the communication between the feeder terminal and the circuit breaker may be affected, resulting in a large impact on accuracy.

[0008] Increased cost: Two sets of independent devices and their installation, debugging, and operation will lead to an overall cost increase.

[0009] If the pole-mounted circuit breaker and the feeder terminal are simply integrated into one device, the mechanical device (pole-mounted circuit breaker) and the electronic device (feeder terminal) will have a huge lifespan gap, which will bring great difficulty to the maintenance of the device.
