基于电子设计的低压电器改进

论述了发电厂和变电所的电气二次设备的新型设计思路,通过电子设计,使低压配电电器和控制电器的工作性能得到改善,节约了成本,同时提高了可靠性,符合小型化、高性能、模数化和组合化的发展趋势.低压配电电器主要对过电流、过载和欠电压状态进行检测,可利用数字式量化处理,从而通过电子电路实现状态分析,进而作出准确判断,触点正确动作.控制电器对准确性要求高,因此可通过电子设计有效提高控制的快速性和可靠性.电子设计思想的引入是低压电器微机式发展的基础,对下一代低压电器的更新具有参考意义.

Improvment of Low-voltageelectrical Equipment Based on the Electronic Design

The new idea is to design the electrical power plants and secondary substation's equipment.The adoption of electronic design shows performance improvement in low-voltage electrical equipment and equipment for controlling,and saves cost,and improves reliability,also in line with the trends of miniaturization,high-performance,analog-to-digital and combination.Low-voltage equipment is used for detection of over-current,overload and under-voltage status.Control of the electrical requires high accuracy,so it can...
