The CT30 type spring energy storage operating mechanism is suitable for installing multiple models of ultra-high voltage self energy sulfur hexafluoride circuit breakers ranging from 110 to 252KV. The product's technical performance indicators meet the requirements of GB1984 "AC High Voltage Circuit Breakers", DL402-9 "Technical Conditions for Ordering AC High Voltage Circuit Breakers" and other standards for operating mechanisms.

The operating mechanism has superior performance and a simple and mature structure. The power can be adjusted freely between 2400 and 4200 joules according to the input power requirements of the circuit breaker. A dedicated buffer device is designed to reduce the rebound during opening and closing and reduce the noise during the opening and closing process. The opening and closing time of the operating mechanism is stable with little dispersion. All control electrical components are made of international famous brand products such as ABB, Schneider, Phoenix, etc. The operating mechanism has been running in the power grid distribution network, with stable and reliable performance.
