本文除分析介紹了集裝箱橋吊的機械繫統組成、電控系統的組成及控制、全數字直流調速器以及plc控制系統的軟硬體設計外,重點研究了集裝箱裝卸橋中的貨物稱重問題,提出了應用電流靜態測量法的稱重方案,並且採用了加速度動態測量法對其進行動態校正,在實際應用中取得了令人滿意的效果。It will effect the system in safety and running economy directly > test of tradition past the method is an usage to give or get an electric shock the bridge method or direct current to press to decline the method to proceed to measure, and the electric current for producing of is only in the ma class which ca n ' t broke through the oxidize surface
高壓斷路器是電力系統中最重要的控制和保護設備之一,它對系統的安全、經濟運行有著直接的影響。以前傳統的測試方法是使用電橋法或直流壓降法進行測量,所產生的電流僅在ma級,不能擊穿觸頭氧化膜。Dc bridges for measuring resistance ; amendment 2
電阻測量用直流電橋.第2次修訂D. c. bridges for measuring resistance
電阻測量用直流電橋In the design of real - time control system, the paper takes three - phase full - bridge mosfet inverter as the real - time control main circuit, and adopts a control scheme with 120 ? switching mode combined with half - bridge pulse width modulation ( pwm ), which would avoid straightthrough short of a certain bridge. phase current is detected by single current sensor ; three - phase position signals generated by position sensors could not only supply commutation information for inverter, but also be used for speed detecting based on signals " period measurement, which makes the speed sensor unnecessary. the whole control system adopts speed and current dual closed - loop control strategy in order to construct a high performance rare - earth permanent magnetic brushless dc motor ( repm bldcm ) full - digital real - time control system
在實時控制系統的設計中,本文以三相全橋mosfet逆變電路作為實時控制主電路,採用120導通方式結合半橋pwm調制的控制方案,從而有效地避免了橋臂的直通短路;本文用單電流傳感器實現對相電流的檢測,來自位置傳感器的三相位置信號不僅為逆變電路提供換相信息,而且也用於基於信號周期測量的轉速檢測,這樣就省去了速度傳感器;系統採用的是速度、電流雙閉環控制策略,力求構建高性能的稀土永磁無刷直流電動機全數字實時控制系統。The portable dc bridge is a device for measuring resistance that be applied widely to field - testing of electric power system
摘要攜帶式直流電橋是一種電隊測量儀器,在電力系統現場測試中應用極廣。D. c. bridge for measuring resistance
