动力UPS在熔体直接纺丝生产中的设计配置分析

Analysis of Power Uninterrupted Power Supply Design Configuration in Melt Direct Spinning Production

由于设计配置及安全防护不当等原因,动力UPS在电网闪络时不能完全给变频器平稳供电,保证其平稳运行。以某20万t/年熔体直接纺丝装置为例,对动力UPS的主要设备的设计配置做了详细说明,并分析了这些配置的合理性、必要性。经在熔体直接纺丝生产实际应用表明,这种配置的可靠性、安全性得到了检验,能够长周期平稳运行,性价比较好。

Because of design confguration and improper safety protection, when the power grid produces fashover, the power uninterrupt-ed power supply （UPS） can’t completely gave stable power supply for the inverter so as to ensure its smooth running. Taking certain 20mil-lion tons per year melt direct spinning device for example, this paper elaborated on the design confguration of main equipment of power UPS and analyzed the rationality and necessity of these confguration. The practical application of melt direct spinning production shows that the reliability and safety are inspected with long period smooth running and better cost performance.
