As for to cracking generating in the course of sub-merge arc weld for longitudinal weld of pressure vessel body by 16MnR steel,This article analyses the causes of the crack,measures such as improving blowout plate,etc.
针对16MnR钢制压力容器筒体纵缝埋弧焊时焊缝终端易形成裂纹的问题,分析其产生原因,并采用改进熄弧板等措施,最终取得了防止裂纹的满意效果。
The influences of the compensation factor of series capacitors in CCC have been investigated on the HVDC transmission system s extinction angle,the active and reactive power flows between the converter and th.
研究了整流侧定电流、逆变侧定电压控制方式下,CCC中串联电容器补偿度对稳态运行中的HVDC输电系统的熄弧角、换流器与系统间交换的有功功率、无功功率、换流母线电压以及换流器的基波功率因数等的影响。
The extinction angle of the DC converter,which is usually used to study the commutation failure of the DC inverter,is an important parameter in the DC transmittal system.
直流换流器熄弧角是直流输电系统的重要电气量,常被用于判断直流输电系统逆变器的换相失败。
