近日,焦作瑞丰纸业有限公司2014年技术创新项目之一“变电站超负荷报警装置”成功启运。该公司110 kV变电站为生产生活电力供应枢纽,经常由于最大负荷控制不好,造成基本电费畸高,影响经济效益,也加大了运行安全风险。为了能够方便快捷掌控电力供应,特别是降低最大负荷用电量,减少电力消耗和不必要的支出,公司动力车间经多方论证对此技术难题进行攻关。攻关小组理论与实践相结合,把瑞101(10 kV进线柜)的电流互感器A项、C项信号串联接到功率变送器,功率变
Recently, Jiaozuo Ruifeng Paper Co., Ltd. in 2014 one of the technological innovation projects “substation overload alarm device ” successfully shipped. The company 110 kV substation for the production of living electricity supply hub, often because of the maximum load control is not good, resulting in abnormal basic electricity costs, affecting economic efficiency, but also increased operational safety risks. In order to be able to quickly and easily control the power supply, in particular, to reduce the maximum load power consumption, reduce power consumption and unnecessary expenses, the company power plant through multiple arguments on this technical problems to tackle. Research team combination of theory and practice, the Swiss 101 (10 kV Incoming Cabinet) current transformer A, C signal connected in series to the power transmitter, the power change
