dead terminal 中文意思是什麼
dead terminal
解釋
盡頭站-
The merit of travelling waves location is its high precision, but it has dead line if the fault location is close to the line terminal or the fault occurs at the time close to zero point of current
行波法測距的優點是精度高，但對近區故障或電流過零附近時刻發生的故障存在測距死區。 -
Because affected by the type of lines, fault resistance and two sides systems ， fault analytical location has lower precision, but it has no dead line and is more better accurate if the fault location is close to the line terminal
故障分析法由於受線路類型、過渡電阻、兩端系統的影響測距精度較差，但故障分析法不存在測距死區，尤其對近區故障的測距較為準確。 -
Compared with conventional methods, the proposed method is not disturbed by reflected waves from tee joints or other resistance discontinuities, and is not influenced by fault type, and can recognize the reflected wave from the fault point even when the fault point is near to the measuring terminal ( so - called dead - zone ), and simultaneously, the method reduces the influence of wave speed uncertainty
與傳統的行波測距方法相比，這種方法不受電纜分支接頭或其他阻抗不匹配點反射波的干擾，不受故障類型的影響，在近區也不存在無法識別反射波的問題，同時也減少了波速不確定性對測距精度的影響。
