摘　　要：在机组运行期间,如果机组润滑油系统故障停运,会造成机组润滑油压降低,存在酿成事故的可能。对某公司机组润滑油泵电动机接线设计中存在的问题进行分析,提出了经工程实践检验合格的解决办法,完善了该电动机接线回路,提高了设备抗电压波动能力。During the operation of unit, if the steam turbine lube oil pump fails to operate, the unit lube oil pressure will be reduced, which may lead to accidents. According to the analysis of the exist problems in the connection design of the lube oil pump motor in a company, this paper puts forward the solutions which are qualified by engineering practice, upgrades the connection circuit of the motor, and improves the anti-voltage fluctuation ability of the equipment.
