Description

Technical Field

[0001] The utility model relates to the technical field of power distribution network, in particular to a spring-operated mechanism for an outdoor primary and secondary deep fusion switch. Background Art

[0002] The primary and secondary fusion switch is also called the primary and secondary fusion complete pole switch. This switch can realize the local feeder automation function without relying on the distribution automation master station and communication. The primary and secondary fusion switch complete set can be divided into section / interconnection circuit breaker complete set, boundary circuit breaker complete set, section / interconnection load switch complete set and boundary load switch complete set according to different application functions. The vacuum circuit breaker is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum. It is widely used in distribution networks for controlling and protecting high-voltage electrical equipment.

[0003] In the prior art, Chinese patent publication number CN206685311U discloses a modular spring-operated mechanism for a vacuum circuit breaker for an indoor high-voltage cabinet, including a spring-operated mechanism body, a base fixedly connected to the bottom of the spring-operated mechanism body, a soft pad fixedly connected to the bottom of the base, a first buffer pad fixedly connected to the bottom of the soft pad, a strong spring fixedly connected to the bottom of the first buffer pad, a second buffer pad fixedly connected to the bottom of the strong spring, a connecting seat fixedly connected to the bottom of the second buffer pad, a connecting rod fixedly connected to the outer surface of the spring-operated mechanism body, a movable rod fixedly connected to the bottom of the connecting rod, a fixed cylinder is provided at the bottom of the movable rod, and the bottom of the movable rod is located inside the fixed cylinder, which has a shock-absorbing effect, reduces the vibration amplitude generated during the transportation of the vacuum circuit breaker, avoids the loosening of the internal connecting elements of the vacuum circuit breaker, and improves the overall service life, which can meet the needs of users and is conducive to promotion.

[0004] However, when the utility model is actually used, shock absorption is performed by a spring, and the spring will reciprocate and expand and contract under strong vibration, which may enhance the vibration and lead to poor shock absorption effect. The shock absorption structure is inconvenient to be disassembled from the spring operating mechanism, and the volume of the circuit breaker is increased during specific installation and use after transportation, which is inconvenient, and therefore needs to be improved.
