ZBQ2-3200GA integrated three-stage design
Performance and Features
Adopting double row composite contacts, transverse pull mechanism, micro motor pre energy storage and microelectronic control technology, basically achieving zero arcing (without arc extinguishing hood)
Adopting reliable mechanical and electrical interlocks, with independent load isolation switches for executing components, ensuring safe and reliable use;
Adopting zero crossing technology, it can be forcibly zeroed in emergency situations (while cutting off two power sources) to meet the needs of fire linkage;
The load isolation switch switching is driven by a single motor, which is reliable, smooth, noiseless, and has low impact force;
The operator drives the motor to only pass current at the moment of switching the load isolation switch, and no working current is required for steady-state operation, resulting in significant energy savings;
□ The load isolation switch is equipped with a mechanical interlocking device to ensure reliable and non interfering operation of the common and backup power sources;
□ It has obvious on/off position indication, padlock and other functions, reliably achieving isolation between power supply and load; Good safety performance, high degree of automation, high reliability, and a service life of over 8000 times;
Integrated electromechanical design, accurate, flexible, and smooth switch conversion, using internationally advanced logic control technology, strong anti-interference ability, and no external interference;
□ Equipped with main power supply and backup power supply; Main power supply split and backup power supply combined; Three stable working modes with both primary and backup power sources disconnected (I-O-II)
Easy to install, the control circuit adopts plug-in terminal connection;
Four operational functions: emergency manual operation, electric remote control operation, automatic control status emergency disconnection operation, and automatic control operation.
