摘要
将Ｌ－Ｃ串联电路串联在交流大电机进线中，并和压敏电阻配合，可实现交流大电机的平衡降压起动，并在切除交流大电机时，起到了抑制对电网电压的冲击，减小拉弧电压，抑制高次谐波等作用。
In order to realize balanced reduced-voltage start of the large AC electric machine, a L-C circuit was in series with the in-line of a large AC electric machine, and matched voltage sensitive resistor.As well it could suppress voltage surge on grid, reduce polar arc voltage and restrain the high harmonicetc. when we cut-off the large AC electric machine.
