对国外引进设备的电气改造

Electrical modification of the imported equipment

论述了多国外引进设备后,电网电压和频率的差异对设备性能的影响,以挤压机为例,叙述了对引进挤压机的在电气系统的改造实例,阐述了OMRON-200H可编程序控制器在挤压机控制中的应用。

The paper recommends after the imported equipment have been take into producing, the difference of electrical network and frequency which influenced the equipment property, with extrusion press modification as example, recounting the actual electrical modification of imported equipment, introduced the OMRON - 200H PLC applied into extrusion press control.
