中文摘要 | 無載同步發電機大部分故障為非對稱故障(Unsymmetrical faults),其包括單 線接地故障(Single line to ground faults)、兩線碰線故障(Double line short faults)及兩線接地故障(Double line to ground faults)。線至地或線至線發生故障 後,故障電流通過之路徑,可能或不可能包括阻抗。由於單條或兩條導體妡路或者由於熔 絲及其他安全設施之動作,不能同時開啟三相電路所造成單條或兩條開路,其結果破壞三 相平衡(對稱),此謂之非對稱故障〔1〕〔3〕。 |
英文摘要 | Broadly speaking the unloaded generator faults can be classified as: 1.Single Line to ground fault on an unloaded generator. 2.Double Line short circuit fault on an unloaded generator. 3.Double Line to ground falult on an unloaded generator. When circuits are controlled by fuses or any device which does not open all three phases, one or two phase of the circuit may be opened while the other phase is closed those faults are characterised by increase in current and fall in voltage. The three phase fault is a unsymmtrical faults. |
