1) Thyristor switch overvoltage and overcurrent in converted course
过电压过电流
3) Overvoltage of direct current
直流过电压
4) cut-off overvoltage
截流过电压
1.
The paper discussed the mechanism of cut-off overvoltage in condition of the first-phase and the rest breaking for three-phase shunt reactor,and proposed the choosing method of resistance and capacitance for R-C absorbing device and introduced the situation of on and off the shunt reactor on site.
阐述了三相并联电抗器首相开断和后两相开断截流过电压的机理,提出了R-C阻容吸收装置的电阻和电容的选取方法,介绍了现场实际合切并联电抗器情况。
5) over voltage during current transfer
换流过电压
1.
RC absorbed circuit mounted in traction winding and components of converter,in order to reduce operation over voltage and over voltage during current transfer.
交直电力机车分别在牵引绕组和整流器元件设置阻容吸收电路以降低操作过电压和换流过电压,探讨了二者在整流器工作过程中的相互作用与影响,当参数选配不当,会造成二极管关断损坏和晶闸管开通损坏,阻容器件也会出现烧损故障;指出当前运用机车普遍存在绕组阻容参数失配情况,以致晶闸管故障率高,阻容器件烧损严重,提出满足各种机车过压保护的优化调整方案。
6) protection against overcurrents; overcurrent protection
过<电>流保护、过<电>压保护
补充资料：春笋之过
1.春笋含有难溶性草酸钙，尿道、肾、胆结石患者不宜多食；含有较多的粗纤维素，对于胃肠疾病患者及肝硬化等患者可能是致病因素。
2.民间认为竹笋湿毒，老人、儿童不宜多吃，每餐最好不要超过半根。另外，老人吃笋一定要细嚼慢咽。
