为了测量小电流电弧中的电子密度，研制了一种夏克-哈特曼激光波前传感器，改进了测量精度，并应用于峰值电流为0.8kA的大气电弧。当瞬时电流降至0.1 kA时，预熄灭阶段的电子密度在差距中心为5 × 1023 m − 3。© 2012 Wiley Periodicals，Inc. Electr Eng Jpn，181（4）：1-8，2012;在线发表于Wiley Online Library（wileyonlinelibrary.com）。DOI 10.1002/eej.22319
To determine electron densities in low current arcs, a Shack–Hartmann laser wavefront sensor was developed, improved in terms of measurement accuracy, and applied to atmospheric arcs with a peak current of 0.8 kA. The electron density in the pre‐extinguishing phase was 5 × 1023m−3at the gap center when the instantaneous current decreased to 0.1 kA. © 2012 Wiley Periodicals, Inc.
