摘要
对莱钢一起发电机大轴磨损事故进行了分析,改进了逆变柜切换装置的滤波电容偏大和直流油泵控制回路的缺陷后,运行效果良好。
It is dealt with the analysis of a main shaft wearing accident of an electric generator, occurred in Laiwu Steel. The reasons are that the filtering capacitance is higher for the switching-over device in the inverter cabinet and the DC control circuit of the oil pump is defective. Through the analysis and improvement, the insolated network achieved good operation effects.
