Negative sequence inverse time overcurrent protection 負(fù)序反時限過流保護(hù)裝置
Inverse time overcurrent relay 反時限過電繼電器
Time overcurrent relay 反時間繼電器
Inverse - time overcurrent protection is used in power supply installation to fit the heat characteristic of the device ' s fault current . with reference to international standard characteristic equations , the equation by the integration of current term is suitable to describe the process of heat accumulation 將反時限過流保護(hù)的概念引入智能電源系統(tǒng),參考國際通用反時限控制曲線,通過構(gòu)造器件的熱庫模型采用微處理器程控能夠方便實(shí)現(xiàn)各種反時限控制特性。
