摘　　要：英格索兰空压机遇闪电瞬间失压又复压后,出现主电机停机,大量空压机油从主机进气口喷出的故障,影响了卷包机组的正常生产。通过对故障原因进行分析,提出了改进措施:①将交流接触器1M的一组常开辅助触点与断油电磁阀5SV线圈串联,当瞬间失压又复压后油就不会通过电磁阀喷向主机;②将1M另一组常开辅助触点串入2M的线圈回路中,可以将系统放空,保证与正常停机状态相同。In case of lightning, Ingersoll-Rand air-compressor's instantaneous break would result in main motor stop, a strong stream air-compressor oil would be forced out of air inlet of main motor and interrupt the normal operation of cigarette making machine. The improving measures were as follows: 1) Serially connecting one set of normal open auxiliary contacts of alternating current contactor 1M and oil cut-off electromagnetic valve 5SV to prevent oil from injecting to main motor through electromagnetic valve when air-compressor was instantaneously cut off; 2) Serially connecting the another set of normal open auxiliary contacts of 1M in 2M coil circuit, system would be emptied to maintain normal stop status.
