性能及特点 / Performance and characteristics

> 采用双列复合式触头、横拉式机构、微电机预储能及微电子控制技术，基本实现零飞弧（无灭弧罩）
> 采用可靠的机械联锁和电气联锁，执行元件采用独立的负荷隔离开关，使用安全可靠；
> 采用过零位技术，紧急情况下可强制置零（同时切断两路电源），满足消防联动需要；
> 执行负荷隔离开关切换采用单一电动机驱动，切换可靠平稳、无噪音、冲击力小；
> 操作器驱动电机只在执行负荷隔离开关切换瞬间通过电流，稳态工作无需提供工作电流，节能显著；
> 执行负荷隔防开关带有机械联锁装置、保证常用、备用电源工作可靠互不干涉，
> 具有明显通断位置指示、挂锁等功能、可靠实现电源与负载间的隔离；
> 安全性能好，自动化程度高，可靠性高，使用寿命 8000 次以上；
> 机电一体化设计，开关转换准确、灵活、顺畅，采用国际先进的逻辑控制技术，抗干扰能力强，对外无干扰；
> 具有主电源全、备用电源分；主电源分、备用电源合，主、备电源均断开三种稳定工作 ( I-O-II)；
> 安装方便，控制回路采用接插式端子连接；
> 四种操作功能：紧急手动操作、电动远程控制操作、自动控制状态时紧急断开操作、自动控制操作。

>Using double-row composite contact, cross-pull mechanism, micro-motor pre-storage energy and micro-electronic control technology, basically
realize zero arcing (no arc-extinguishing cover)
>Reliable mechanical interlock and electrical interlock, the actuator adopts independent load disconnecting switch, which is safe and reliable to use;
>Using zero-crossing technology, it can be forced to zero in case of emergency (cut off two power sources at the same time) to meet the needs of
fire protection linkage;
>The execution load isolating switch is switched by a single motor, and the switching is reliable and stable, no noise, and the impact force is small;
>The operator drive motor only passes the current when the load isolating switch is switched. The steady-state operation does not need to provide
the working current, and the energy saving is remarkable;
>The implementation of the load isolation switch with mechanical interlocking device ensures that the common and standby power supplies work
reliably and do not interfere with each other.
>With obvious on-off position indication, padlock and other functions, reliable separation between power supply and load;
>Good safety performance, high degree of automation, high reliability, and service life of more than 8,000 times;
>Mechatronics design, switch conversion is accurate, flexible and smooth, adopts international advanced logic control technology, strong anti-
interference ability, no external interference;
>With main power supply and backup power supply; main power supply and backup power supply, main and backup power supply are disconnected
for three stable operations (I-O-II);
>Easy to install, the control circuit is connected by plug-in terminal;
> Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control
state, automatic control operation.
