一种塑壳断路器电子脱扣器的设计OA
Design on Electronic Release of Molded Case Circuit Breaker
随着我国智能电网建设的推进,电子式脱扣器的应用日益广泛.采用双心电流互感器采样主回路电流,配备液晶屏幕与按键,设计了一种可以连续调整保护参数的电子脱扣器.实践表明,所设计的脱扣器保护精度高、保护种类繁多,且具备状态显示、脱扣器自诊断、辅助输入输出、历史日志、通信等功能,满足智能电网对断路器的智能化要求.
With the construction of smart grid in China,the application of electronic circuit breaker is widely used.A dual core current transformer is used to sample the main circuit current,and an electronic release equipped with a LCD screen and buttons that can continuously adjust protection parameters is designed.Practice has shown that the designed release has high accuracy,a wide variety of protection types,and functions such as status display,self diagnosis,auxiliary input and output,historical logs,and communication,which meet the intelligent requirements of the smart grid for circuit breakers.
