如今,电动机正逐步代替燃气轮机,作为天然气液化厂冷剂压缩机的驱动设备,通过变频器与电网相连,不但启动便捷,有良好的功率匹配性,而且安全性有很好的保障,使用寿命长,检查维修方便、成本较低,应用十分广泛,但同时也存在着系统复杂、不好控制等不足,在今后的发展中需要不断改进。
Now, the electric motor is gradually replacing the gas turbine. As the driving device of the compressor for the compressor of the natural gas liquefaction plant, it is connected with the power grid through the frequency converter. The utility model has the advantages of convenient starting, good power matching, good safety and long service life , Inspection and maintenance of convenience, low cost, the application is very wide, but there are also system complexity, poor control and other deficiencies in the future development needs continuous improvement.
