The principle of operating mechanism

The spring operating mechanism is divided into three parts: spring accumulator, maintenance close and maintenance open. It consists of about 200 pieces. The isolation switch consists of the expansion and expansion of the spring and the kinetic energy stored in the mechanical device. According to the operation of the motor of the energy storage reducer, the storage of kinetic energy of the spring and the closing and disconnecting state of the isolation switch are controlled by the electromagnetic coil. Brake spring and closing spring are the core components of spring operating mechanism. The mechanical function of the motor is stored in the closing spring for a short time, and then the closing spring is released for closing; During the entire process of opening the brake, the opening spring stores energy as a driving force. Therefore, the kinetic energy of the isolation switch to turn off the equipment and disconnect operation is the kinetic energy stored in the spring, which is independent of the magnetic field force, and does not require excessive closing current.
