Description

Technical Field

[0001] This utility model relates to the field of circuit breaker assembly technology, and in particular to an assembly tooling and system for a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] Primary and secondary integrated pole-mounted circuit breakers are one of the core components of outdoor distribution network systems. They are widely used in power distribution networks and play a vital role in connecting, demarcating, and disconnecting outdoor overhead lines. With the construction of new power systems and the deepening application of smart grids, distribution networks not only undertake the traditional task of receiving and distributing electrical energy from the main grid, but also, with the large-scale application of distributed renewable energy access, take on the role of integrating distributed energy sources and aggregating electrical energy to the main grid. It can be seen that the role of distribution networks in new power systems is becoming more important. Therefore, both the power grid and end users have put forward specific requirements for the integration of primary and secondary circuit breakers in distribution systems, especially for circuit breakers, which are core components, requiring more specific integration, standardization, and specialization.

[0003] Pole-mounted circuit breakers are mainly composed of three major components: the operating mechanism, the fusion pole, and the electrical control system. The main production process includes machining of mechanical transmission components, bending / welding / surface treatment of the mechanism box, final assembly, debugging, and inspection and testing. Since pole-mounted circuit breakers are normally installed on outdoor poles with crossarms, the product lacks a large and stable fixing surface. In addition, there are assembly work points on all sides of the pole-mounted circuit breaker, which makes it impossible for operators to operate in a fixed position during assembly. Multiple people are required to cooperate to perform auxiliary operations such as flipping and tilting the pole-mounted circuit breaker, resulting in cumbersome and inefficient operations, which is not conducive to the rapid construction and delivery of batch projects.

[0004] Therefore, a primary and secondary integrated pole-mounted circuit breaker assembly tooling and system is provided to solve the above-mentioned technical problems existing in the prior art. Utility Model Content
