Firstly, when the 10kv high pressure motor start up, the rate of false action caused by automatic switch protector ( asp ) will raise dramatically ; secondly, at moment of on / off switch, great electromagnetic flux induced in the asp cause damage
一是在10kv高壓電機的啟動時,高爆保護器的誤動作率明顯提高;二是在分合閘瞬間,較大的電磁影響甚至造成了保護器的損壞。The main circuit is consisted of 18 thyristors circuit and protection circuit. with the help of control subsystem, it can get the output of low frequency voltage ( current ) with the shape of sine wave ; the core of the control subsystem is the cpu of 87c196kc, and the synchronization circuit, the pulse - widen circuit, and the power - enlarged circuit form the accessorial subsystem of the control system. it possesses all the functions of digital triggering, digital tuning, analog / digital conversion ; the input transfer can isolate the input and output ; and the circumfluence reactor can reduce the circumfluence
主迴路採用由18個晶閘管組成的三相零式電路,並輔以晶閘管的保護電路,通過控制可以得到低頻正弦波的電壓(電流)輸出;控制迴路主要以87c196kccpu為核心,其外圍電路包括同步電路,脈沖拓寬電路,功率放大驅動電路等,完成了數字觸發、數字調節、模數轉換等功能;進線電源變壓器具有變壓和隔離作用;環流電抗器則實現了有效抑制主迴路瞬時脈動環流的功能。Instrument transformers - requirements for protective current transformers for transient performance
儀表變壓器.保護電流變壓器瞬時特性要求As the kernel of software, the algorithm is another emphasis of the paper ' s works. based on the principle of relaying working, after comparing the effect between the algorithm of instantaneous sampling and the algorithm of vector, the virtue of short data windows and precision action was stood out. and the choice of algorithm with three sampling data was for the reason of short data windows
演算法理論作為微機保護的軟體核心也是本文的討論重點,以保護的動作原理為基礎,認真研究了采樣瞬時值法與一般的矢量值法的效果比較,突出了采樣瞬時值法時間窗短、動作準確的優點;而針對低電壓閉鎖所採用的三采樣值積演算法也正是出於時間窗較短,便於配合保護動作的考慮。分享友人
