消弧线圈在铝加工企业供电系统中的应用

Applications of Arc Suppression Coil in the Power Supply System of an Aluminum Fabricating Enterprise

针对小电流接地系统中单相接地存在的隐患,介绍自动跟踪消弧线圈补偿技术的原理、性能和特点。采用该装置可以自动实施最佳补偿,减小故障点的残流,有效抑制弧光过电压的危害,预防因单相接地而引发的相间短路及电缆放炮等故障。

To solve hidden troubles existed in the single phase grounding of small current grounding systems,a compensation technology of tracing the arc suppression coil automatically is introduced including its principle,properties and features. Adopting a device of the technology will be good for acting best compensation automatically,decreasing remainder currents in fault points,restraining effectively damages of the overvoltage arc lighting,preventing some faults such as the phase to phase short circuit caused by the single phase grounding,the explosion of cables,etc.
