Features: Adopting double-row composite contact/transverse pull structure/micro-motor energy storage and micro-electronic control technology, it basically realize zero arc over. Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, automatic control operation. Adopting reliable mechanical and electrical interlocking, the actuator adopts independent load disconnecting switch, safe and reliable to use. Adopting zero-crossing technology, it can be forced to zero (disconnect two power supplies at the same time) in emergency situations to meet the needs of fire linkage The load isolating switch is switched by a single motor drive, the switch is reliable and stable. The operator drive motor only passes the current when the load isolating switch is switched, and the energy saving is remarkable. The load isolating execution switch is equipped with mechanical interlocking device to ensure that the main and backup power supply work reliably and do not interfere with each other. With obvious on-off position indication, padlock and other functions, realizing the safety isolation of power and load, safe and reliable. Mechatronics design, switch transfer is accurate, flexible and smooth; Adopting advanced logic technology, with strong anti-interference capability. Applicable for automatic conversion between main power supply and backup power supply in power supply system, automatic conversion and safety isolation of the two loading equipment.
