小型选择器

The task uses the microelectronics technology and single-chip technology and utilizes microprocessor to develop the mini-intelligence releaser. It can not only fulfill the function of releasing, i.e. fulfill the protecting function which is pre-designed, but also select the parameters of motion, i.e.

本课题利用微电子技术及单片机技术，采用微处理器，设计出小型的智能断路器，不仅能够实现预想的保护功能，还能对脱扣器的动作参数进行选择即可实现对多种不同场合的保护。

The task uses the microelectronics technology and single-chip technology and utilizes microprocessor to develop the mini-intelligence releaser. It can not only fulfill the function of releasing, i.e. fulfill the protecting function which is pre-designed, but also select the parameters of motion, i.e. it can realize protecting in the multi-situations. By using the system, the target of remote controlling is realized .All of them strengthen the releasers functions and make it accord with requirements of distribution system.
