摘要
介绍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 ,为什么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 characteristics of electricity load for portal crane and electric welding machine of shipyard were introduced in the paper. The principles of reactive compensation of quick “on off” capacitor set of thyristor, the advantages of technique and the obvious efficiency of economy of it were also described in the paper.
