Features: 1. Adopt double-row composite contact/across-pull mechanism/micro-motor pre-storage energy and micro-electronic control technology to achieve 0 arcing (no arc-extinguishing cover) 2. Reliable mechanical interlock and electrical interlock, the actuator adopts independent load disconnecting switch, which is safe and reliable. 3. Adopting 0-crossing technology, it can be forced to 0 in emergency (two power sources are cut off at the same time); the load isolating switch is switched by single motor drive, the switch is reliable and stable, no noise, and the impact force is small. 4. The operator drive motor only passes the current when the load isolating switch is switched, and the energy saving is remarkable. 5. Execute the load isolating switch with mechanical interlocking device to ensure that the common and standby power supplies work reliably and do not interfere with each other. 6. With obvious on-off position indication, padlock and other functions, reliable realization of power and carrier isolation 7. Good safety performance, high degree of automation, high reliability and service life of more than 8000 times 8. Mechatronics design, the switch conversion is accurate, flexible and smooth, adopts international advanced logic control technology, strong anti-interference ability, no external interference 9. With main power supply, backup power supply; active source and backup power; main and backup power are disconnected three stable work (I-0-II) 11. Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state and automatic control operation. 13. It is widely used in power transmission, distribution systems and automation systems for hospitals, banks, high-rise buildings and other important power supply places that are not allowed to be powered off.
