低压供电在线监测系统在楼宇自动化中的应用

摘要

针对380/220 V低压供电系统的状态监测常被忽视，而造成严重经济损失或人身伤亡的情况，介绍了一种利用数字电力测量仪表组成的楼宇低压供电参数在线监测系统。该系统对监测回路主要供电参数及断路器通断状态进行实时监测，并形成供电负荷曲线及报表，增强了供电事故预防能力，提高了楼宇供电管理效率，并为楼宇供电系统扩容改造提供重要依据。%Aiming at that the state monitoring of 380/220 V low-voltage power supply system is often ignored, so as to cause serious economic losses and casualties, this paper introduced a kind of on-line monitoring system, with building low-voltage power supply parameter, using digital power measuring instrument. The system monitored main loop power supply parameters and circuit-breaker on-off state in real time, forming the power load curve and statements, enhancing the power supply accident prevention capabilities and improving the building power supply management efficiency, which provide an important basis for the future dilatancy and re-vamping of building power supply system.
