external fault meaning in English
外部故障
Examples
- Internal and external fault behaviour of safety related electronic parts of gas appliances
涉及安全性的燃气器具电子部件的内外故障特性 - The technique can distinguish external fault , internal fault and switching on slight fault , without information concerning parameters of the transformer and power system is required
该方法能迅速有效的区分区外故障与区内故障，以及空载合闸于轻微故障的故障电流。 - Even if the fault spread from external fault zone to internal fault zone , the differential protection can avoid misoperation . main criterion of protection is composite - percentage current differential algorithm according to every sampled value , which can accelerate the protection ' s trip , reduce large amounts of calculation and have strong stability to ta saturation
本文采用基于采样值的比率制动式电流差动保护算法作为保护的主判据，可以明显提高保护动作速度和减少计算量；具有较强的抗ta饱和能力，在区内故障时无制动，区外故障时有极强的制动特性。 - In the models , the iron core nonlinearly of the traction transformer and the magnetic hysteresis effect without the b - h curve are considered . having tested by digital simulation , the winding parameter has not changed in the state of external fault or magnetizing inrush etc . but the winding parameter has obviously changed in state of inter fault or inter - turn fault . ( 3 ) the rules three phases converted to two phases of traction transformer in electric railways are developed in this paper
（ 3 ）利用牵引变压器磁链平衡方程，建立了基于系统辨识理论的双绕组单相接线牵引变压器、阻抗匹配平衡牵引变压器及scott （斯科特）接线牵引变压器的“灰箱”模型，该模型考虑了牵引变压器铁芯非线性和磁滞效应，但又不直接反映在模型中，并且无需铁芯的b - h曲线数据。
