earthed fault 中文意思是什麼
earthed fault
解釋
接地故障-
Based on researching the function of every kind of eliminating arc loop, new concept was brought up in this paper, and the protective device for eliminating arc and overvoltage was researched and manufactured. when the arc light connecting the ground emerges, the chip synthesizing controller control the vacuum contacter which can be operated with dividing phase and make its fault phase earthed so that the arc light can be dissolved thoroughly
本文在研究各種消弧線圈的基礎上，提出全新的概念，研製出了消弧及過電壓保護裝置，該裝置在出現弧光接地時，通過單片機綜合控制器控制一組可以分相操作的真空接觸器，使故障相接地，達到徹底消除弧光的目的。 -
Analysis of transient characteristics of signals phase earth fault in non - solidly earthed network
中性點非直接接地電網單相接地故障暫態特徵分析 -
Single phase earthed fault is the common fault in this system. to detect the faulty feeder is difficult for the fault current is very small
單相接地短路是最常見的故障，由於它的接地短路電流較小，使故障檢測較困難。 -
By analyzing the refraction 、 reflection process of fault transient current traveling wave of high voltage and characteristics of refraction 、 reflection coefficient systematically, a new fault location method of single ended traveling wave is presented. it can not only identify the reflection wave for fault location efficiently, but also not be affected by the structure and length of line. fault earthed resistance 、 fault type 、 system impedance and can locate fault in adjacent areas accurately
論文深入地分析了高壓線路故障暫態電流行波的波折、反射過程以及折、反射系數的特點，提出了新的單端行波故障測距方法，它不僅能夠有效地識別出測距所用的反射波，而且幾乎不受線路結構、長短、故障接地電阻、故障類型、系統阻抗的影響，在近區仍可以準確地進行測距；同時模擬阻波器的特徵，設計了低通數字濾波器，對通過了低通數字濾波器的暫態故障電流行波再次進行小波分析，並利用本文提出的單端行波故障測距方法進行故障定位，結論是所提出的測距方法在實際應用中仍是有效的。 -
B fault detection : detection and indication of inter - phase and earthed phase fault, detection of broken wire, transmission of fault data, fault isolation and service restoration
故障檢測功能：檢測故障發生的時間歷時過程，故障電流電壓的幅值和方向，故障錄波和報文記錄，故障遙測報文上送，與配電主站配合完成故障隔離和事故恢復。 -
When single phase earthed fault occurs, it is necessary to select the fault circuit quickly
