Switchgear for aircraft. miniature sealed reverse current double pole relays
飛機電氣開關裝置.小型密封逆流雙極繼電器Switchgear for aircraft. 1. 5 ampere double pole reverse current midget relays
飛機電氣開關裝置. 1 . 5a小型雙極逆流繼電器The direct torque control theory is a kind of new control method after vector control theory in ac control field. it calculates and controls the torque and the flux of ac electromotor in stator coordinate using the voltage space vector. adopting the stator magnetism field direction method, it recurs to discrete pang - pang control producing pulse width modulation signal and controls the switch state of the transductor when better quality steady - state performance is produced
直接轉矩控制技術是繼矢量控制技術之後交流調速領域中新興的控制技術,它採用空間矢量分析的方法,直接在定子坐標系下計算並控制交流電動機的轉矩和磁鏈,採用定子磁場定向,藉助于離散的兩點式控制產生脈寬信號,直接對逆變器的開關狀態進行最佳控制,以獲得轉矩的高動態性能。Current transformers are nonreplaceable in the field of protection and measurement for decades, but the electromagnetic current transformers can not meet the development of the electric power system for the reasons of magnetic saturation, ferro resonance, little dynamic range, narrow service band and so on 。 with the popularization of microcompute, it will be irreversible to apply microcompute in the protection and measurement, the equipments do not need the current transformer with high power, so the rogowski coil can apply on the field of protection and measurement
電流互感器在繼電保護和電流測量中的作用長期以來具有不可替代的地位,但電磁式電流互感器所固有的磁飽和、鐵磁諧振、動態范圍小、使用頻帶窄等都難以滿足電力系統發展的要求。隨著微機的普及,在繼電保護和測量中應用微機已是不可逆轉的潮流,設備已不再需要高功率輸出的電流互感器,因此可以選用rogowski線圈作為低電壓輸出要求的電流測量和繼電保護應用。Switchgear for aircraft. 10 amperes miniature sealed reverse current double pole relays
