Fault line detecting with zero sequence active power and optimization of single phase grounding fault disposing process with neutral grounding via arc extinguishing coil system 零序有功选线与消弧线圈接地系统单相接地故障处理过程优化
At last, the experiments are carried out for active control of ( 0,0) mode and ( 1,0) mode in the square duct. A METHOD OF OPTIMIZATION OF COIL WITH EXTENDED SURFACE 最后,进行了控制方截面管中(0,0)次波(平面波)和(1,0)次波的实验.肋片管簇优化方法
The active Electronic current transformer ( ECT) with air core coil as transducer, compared with conventional transformer with iron core coil as transducer, has excellent transforming characteristics, high precision and wide bandwidth. 有源型电子式电流互感器以空心线圈或光学元件作为传感元件,相对于以铁芯线圈作为传感头的传统互感器,具有优良的传感特性、高精度以及宽频带。
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。
