第一个技术问题是实现感知功能。这是智能化的基础，该功能的实现必须依托现代传感器技术来获取如电压、电流、绝缘（局放）、距离、速度、温度等信息，传感器将这些信息转换成能被识别和处理的各种信号，这些信号能准确、可靠、灵敏的反映信息的变化，传感器除自身必须具有高质量、高可靠性外，还应有适应断路器工作环境、体积小、便于安装的特点。

The first technical problem is realizing the perception. This is the foundation of the intelligent, the realization of the function of the must rely on modern sensor technology to obtain such as voltage, current, insulation (partial discharge), distance, speed, temperature and other information, sensor converts the information can be identified and processing of signal, the signal can be accurate, reliable, sensitive reflect the change of information, sensor except itself must have a high quality, high reliability, also should be adapted to the breaker working environment, the characteristics of small volume, easy to install.

　　第二个技术问题是实现思维判断功能。这是智能化的核心，该功能的实现必须依靠现代电子技术、计算机技术和通信技术。智能控制器的输入既有来自感知功能获取的信息，又有来自执行功能反馈的信息，还有来自系统的控制信息；智能控制器综合这些信息后，可自动识别断路器的工作状态、自动调整断路器的操作信息、自动记录关键信息、自动对断路器的元器件和操作进行诊断等智能思维判断；智能控制器的输出一方面为执行功能提供操作指令，另一方面为系统提供断路器工作状态信息。智能控制器除具有智能思维判断功能外，还必须具有高可靠、长寿命、强抗电磁干扰功能。

The second technical problem is realizing the function of thinking. This is the core of intelligence, which must rely on modern electronic technology, computer technology and communications technology. The input from a smart controller comes from information that is obtained from the perceptive function, and information from the performance feedback, and the control information from the system; Intelligent controller integrated these information, can automatically identify the circuit breaker working condition, the automatic adjustment of circuit breaker operation information, automatic record key information, automatic components and operation of circuit breaker diagnosis intelligent thinking and judgement; The output of the intelligent controller provides operational instructions for performing functions, while also providing the system with the working state information for the circuit breaker. Besides intelligent thinking, intelligent controller must have high reliability, long life and strong anti-electromagnetic interference.

　　第三个技术问题是实现执行功能。执行功能必须按控制器发出的操作指令进行可靠的操作，完成断路器的关合与开断；同时，执行功能必须具有高可靠、长寿命、体积小的功能。目前已开发和应用的永磁操作机构已基本能满足智能化断路器对执行功能的要求。

The third technical problem is implementing the execution function. The execution function must be operated reliably by the operation instructions issued by the controller, complete the closing of the circuit breaker and the break. At the same time, the execution function must have high reliability, long life, small volume function. The permanent magnet operating mechanism has developed and applied to meet the requirement of intelligent circuit breaker to perform function.
