Product description

The CTD-III spring mechanism is a high-power three-phase mechanical operating mechanism that uses springs as energy storage components. The energy storage of the spring is achieved through the rotation device of the motor and the transmission of various gears, and is maintained in the energy storage state through the energy storage and maintenance system. When disconnected, the energy storage and maintenance is released by the magnetic force of the electromagnetic coil, causing the spring to release energy, and the contact to move through the mechanical transmission unit, Thus achieving the opening and closing operation of the circuit breaker switch. Its structure forms a symmetrical arrangement, with high operational power, simple structure, low transmission loss, high stability and reliability.

At present, the institution is mainly used in single-phase linkage operated circuit breakers, high-voltage SF6 circuit breakers, and fully enclosed switchgear (GIS) with voltage levels of 220KV and 550KV. Its performance meets the requirements of GB1984 "AC High Voltage Circuit Breakers", IEC56 "High Voltage AC Circuit Breakers", and the "Technical Conditions" of this product.
