多晶硅厂DCS失电故障原因分析及其应对措施

Failure analysis and its countermeasures of power-lossing in DCS of polysilicon plant

DCS在有效提升多晶硅生产管理水平、优化工艺的同时,其在稳定和可靠性方面对多晶硅生产装置安全运行产生了一些负面影响,如DCS的失电故障,导致生产装置局部或全部停车,如果处理不当会损坏设备,危及到生产人员的安全,可能造成工厂毁灭性的灾难。对DCS失电故障原因进行了分析,提出了DCS的配电方式和对不间断供电电源(UPS)的工作电源、旁路电源、直流电源均设置失电报警功能等措施。

DCS effectively enhance the level of polysilicon production management, process optimiza- tion, stability and reliability of the safe operation of the polysilicon plant produced some negative effects, such as loss of power failures in the DCS, resulting in partial or full stop of the production unit, if not handled may cause damage to equipment, en factory devastating disaster. Loss of electrical danger the safety of production personnel, may result in the malfunction in the DCS, the DCS distribution and uninter- ruptible power supply （UPS） power bypass power, DC function and other measures. power supplies are set to the power failure alarm
