摘要
目的:在无人职守运行条件下,基于站内自动控制,提出了城市供暖热力站站内发生运行故障时的全自动电气设备保护方案。方法:通过热力站自控柜对现场各种运行参数的采集以及对热力站内各种电气设备的控制。结果:在无人职守条件下发生故障时,热力站自控柜可通过程序自动保护站内各种电气设备,大大降低了设备损坏比例。结论:通过电子仪表采集现场信号及热力站自控柜处理,完全可以实现对热力站内各种电气设备的保护功能。
Objective： To put forward an automatic electric equipment protection scheme for urban heating thermal station when the operating failure occurs based on the unmanned operating conditions and automatic control within the station. Method： To collect various site operation parameters through thermal station’s automatic control cabinet and to control various electric equipment of the thermal station. Result： Tthermal station’s automatic control cabinet can automatically protect the electrical equipment within the station through various programs when the operating failure occurs under the unmanned operating conditions,greatly reducing the equipment damage rate. Conclusion： The collecting of the site signals through the electronic instruments and the processing through thermal station’s automatic control cabinet can completely realize the protection function of various kinds of electrical equipment in the thermal station.
