摘　　要：电弧炉属于一种典型的冲击性负荷,其主要特点是快速、随机的功率波动,由此带来的电压闪变及波形畸变使得传统的计量方式不适用冲击性负荷下的计量。本文分析了电弧炉的运行特点,通过模拟实验,得出了这种现象形成的原因,并提出了如何消除冲击性负荷对计量的影响见解。The Arc Furnace is a kind of typical impulse load, the randomness and the impact toughness are its main features. Voltage flick and waveform distortion, resulted from it, make it unfit for the traditional measurement in the impulse load＇s metrology. In this paper, the author analysises the operational characteristics of the Arc Furnace, make a conclusion on the cause of this phenomenon through simulation experiment, and put forward his own opinion in how to eliminate the effect of impulse load on the measurement.

关 键 词：冲击性负荷 运行 计量 电压闪变
