Improvement of 4^(#)TRT Low-voltage Power Supply System Bus Coupler Spare Power Automatic Switching Device

随着钢铁企业的不断发展以及电气自动化普及,低压供电系统需要采取更加稳定、可靠、智能的设计方法,有效减少停电次数和停电时间、造成设备故障及经济损失.为此,改进常规继电器控制方式,使用低压0-400V、DCAP-5030母联监控保护及综合备自投装置,具有非常重要的意义.

With the continuous development of iron and steel enterprises and the popularization of electrical automation,low-voltage power supply system needs to adopt more stable,reliable and intelligent design methods to effectively reduce the number and time of power outages,resulting in equipment failure and economic losses.Therefore,the conventional relay control mode is improved,and the low-voltage 0-400V,DCAP-5030 bus coupler monitoring protection and integrated spare power automatic switching device are used.It is of great significance.
