摘　　要：随着科学技术的进步,电子脱扣器在部分使用范围内已逐步替代了热磁脱扣器。提出了一种电子脱扣器的设计:采用电流互感器采集线路回路中的电流信号;采用液晶显示屏进行运行状态和运行参数的显示,同时结合输入按键完成电子脱扣器参数数据的连续设定。实践证明,该电子脱扣器保护精度高,保护类型种类多,且具备通信、接地、漏电、区域联锁等功能,完全符合我国智能电网未来发展建设的需要。With the progress of science and technology, electronic circuit breaker in the part of the scope of usehas gradually replaced the thermal magnetic tripping device. This paper proposed the design of an electronic trippingdevice. The device uses current transformer to collect current signal; the LCD screen to display the running state andparam eters, combined with input button to complete the electronic circuit breaker param eter data set continuously.The production practice shows that the electronic tripping device has high precision of the protection, many kinds oftypes of protection, and com m unication, grounding, leakage, regional interlock protection function, in full compliancewith the need for the future construction and development of smart grid in China.
