Why Is The Operating Mechanism Of Sf6 Circuit Breakers So Stable?

Precise transmission ratio design is a core factor in maintaining the stability of the sf6 circuit breaker operating mechanism mechanism. The working cylinder and arc-extinguishing moving contact within the hydraulic mechanism employ a 1:1 transmission ratio. This design ensures direct and effective mechanical response, with mechanism stability exceeding 3000 cycles. Precise coordination of the transmission chain ensures consistent performance in every operation, reducing the impact of accumulated errors on the system.

Multiple protection systems enhance the operational reliability of the mechanism. Monitoring components such as signal cylinders, density relays, pressure switches, and safety valves provide real-time control of the mechanism's status. When SF6 gas leaks or the hydraulic system pressure is abnormal, these devices immediately identify and issue alarm signals, preventing the mechanism from continuing operation under fault conditions. The application of mechanical interlocks and a gate valve system further mitigates risks such as "slow opening due to pressure loss," ensuring the accuracy of opening and closing operations.

The characteristics of hydraulic transmission give the sf6 circuit breaker spring mechanism a natural advantage in stability. Compared to electric drives, the driving force provided by a hydraulic system is continuous and uniform, without sudden shocks during operation. This smooth mechanical characteristic ensures a stable trajectory of the moving contact and uniform contact pressure, thereby improving overall operational accuracy. At the same time, the buffering properties of hydraulic oil absorb some of the mechanical vibration, reducing noise pollution.
