浇注式电流互感器高动热稳定电流的设计
Discussion on the short-time withstand current density
关于短时耐受电流密度值
Technology of Direct Boronizing Co-crystallization with Short-time Heat by Low Voltage and Strong Current
低电压大电流短时加热直接渗硼共晶化工艺
In order to greatly enhance the zero-sequence current active component during the single-phase ground fault, the short-time switch and the resistance paralleled with the petersen coil were controlled when there is a permanent single-phase ground fault in the system.
该方法当系统发生永久性单相接地故障时通过控制开关短时投切与消弧线圈并联的电阻,从而大大增强单相接地故障时的零序电流有功分量。
