摘 要:勵磁涌流是變壓器空載合閘時不可避免的現(xiàn)象。從實驗角度對勵磁涌流的表現(xiàn)加以分析,并以晶閘管配合交流接觸器作為核心器件,制造了合閘相位角可控的勵磁涌流發(fā)生控制裝置,模擬實際中可能出現(xiàn)的各種勵磁涌流現(xiàn)象,進行相關勵磁涌流峰值、衰減特性等的分析。試驗結果表明該裝置可作為勵磁涌流計算的有效驗證手段。
關鍵詞:勵磁涌流;晶閘管;合閘相位角

Abstract: The excitation inrush current is the inevitable phenomenon in transformer no-load closing. This paper analyzed the phenomenon of excitation inrush current from the corner of experiments. An excitation inrush current generation control device, controlled by the closing phase angle, with thyristors and AC contactor as the core components, was manufactured. This paper simulated various possible arisen phenomena of excitation inrush current in practice and analyzed the related peak value of excitation inrush current, the attenuation characteristics and so on. Experimental results show that the device could be the effective verification way to calculate excitation inrush current.
           Key words: excitation inrush current; thyristor; closing phase angle
