摘要
分析港口门座式起重机和船厂广泛运行的电焊机用电负荷的特点 ,阐明采用低压交流接触器自动投切电容器的无功补偿屏为何不能跟踪门座式起重机和电焊机的用电负荷变化的原因。叙述晶闸管快速投切电容器组的无功补偿原理 。
The features of the load of protal crane in the harbour and of welder in the ship factory were analyzed. The cause was expounded why can not follow the load changes in the protal crane and welder when reactive compensation with capacitor bank quick changed over by AC contactor. The principle of reactive compensation with capacitor bank quick changed over by thyristor, their technical advantages and remarkable economic efficiency were described.
