摘要
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。
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 miniaturiza- tion, 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 effectively improve the control and reliability through electronic design. The introduction of electronic design is the basement of low-voltage electrical microprocessor development, and it has reference value for the development of next-generation low-voltage electrical updates.
