%X 石化大功率电动机的安全快速起动是保障石化企业稳定生产的关键因素，因此对大功率电动机起动方式的研究具有重要意义。变压器–电动机组起动是目前国内石化企业采用较多的一种启动方式。文章以某炼化企业的100万吨/年乙烯及配套项目空分装置电动机为工程案例，通过设计手册算及仿真建模分析对变压器–电动机组起动方案的特点及经济性进行了分析。经过分析得出变压器–电动机组起动方式具有可靠性强、经济性强的特点，采用此种起动方式可保障石化装置的安全稳定生产。<br />
The safe and fast starting of high-power motor is the key factor to ensure the stable production of petrochemical enterprises, therefore it has great significance to study the starting scheme of high-power motor. Transformer-motor unit starting is a kind of starting mode which is widely used in domestic petrochemical enterprises at present. This paper takes 1 million tons/year ethylene of a refinery and its supporting project air separation unit motor as an engineering case. Through calculation of design manual and simulation modeling analysis, the characteristics and economy of the starting scheme of transformer-motor unit are analyzed. Through analysis, it is concluded that the transformer-motor unit starting scheme has the characteristics of strong reliability and economy, and this starting mode can ensure the safe and stable production of petrochemical plants.
