东芝三菱XL75高压变频器二用一备在线热穴余方案在京博石化204万吨年K-COT丙烯制冷压缩机上的应用

The Application of TMEIC XL75 High Voltage Inverter Dual Use One Standby Redundancy Scheme in 2.04 Million Tons Per Year K-COTPropylene Refrigeration Compressor of Jingbo Petrochemical Co.LTD.

本文简单介绍了采用二用一备在线热几余方案的东芝三菱的XL75五电平高压变频器,在京博石化K-COT丙烯制冷压缩机上的应用。该系统可以在任一台变频器故障的情况下,利用另外两台变频器继续自动带丙烯压缩机满载运行,变频器的故障不会造成机组停机。

This article briefly introduces the application of TMElC XL75 high voltage inverter dual use one standby redundancy scheme in 2.04 million tons per year K-CoT propylene refrigeration compressor of Jingbo Petrochemical Co.LTD..The system can use the other two inverters to continue the full load operation of the propylene compressor when one inverter fails,and the failure of the inverter will not cause the unit to stop.
