Abstract1. Model and Name: Circuit Breaker Spring Mechanism CT1702. Main application and performanceThis mechanism can operate 126kV high voltage SF6 circuit breaker and gas insulated switchgear (GIS). Its performance meets the requirements of GB1984 "AC High Voltage Circuit Breakers", IEC56 "High Voltage AC Circuit Breakers" and "Product Technical Conditions".The mechanism can be electric energy storage and manual energy storage. Switch operation is divided into remote control operation, near electric operation and manual operation.3.

ZN13 type spring-operated actuator is used to operate ZN12/ZN13 type indoor vacuum circuit breakers and other outdoor or indoor vacuum circuit breakers whose closing power is comparable to that of the former. Its performance meets the requirements of GB1987 AC High Voltage Circuit Breakers and product technical conditions.The closing spring energy storage methods of the mechanism include electric energy storage and manual energy storage. Solenoid and manual button can be used for opening and closing operation.

Product DescriptionIt has a rotating arc extinguishing method that utilizes the electromagnetic force generated by the current flowing in the main circuit of the switch to cut off the current, reducing the burden on the operating mechanism.The shell is formed by hydraulic expansion with 1500 air pressures, with the smallest welding length and the strongest circular shape to withstand internal and external pressure, thus maintaining high accuracy and high quality.Product Technical Parameters1.Rated voltage: 12KV2.Rated current: 630A3.Rated short time withstand current: 20KA4.Rated short time wi
