| 摘 要： | 匝间短路是变压器最主要故障形式之一,绕组一旦出现此故障,最终会引起变压器的损坏.目前的仪器一般通过波形的对比、阻值的变化等进行判断,对轻微的或只有少数匝绕组有短路的情况只能束手无策.此时,可以通过对短路时变压器的电阻、电流分析,以及对变压器的漏磁场、短路时的电动力、短路时的温度等主面进行诊断,从而对变压器绕组进行有效筛选. |
| 关 键 词： | 变压器 匝间短路 故障检测 |

| Abstract: | Turn-to-turn short circuit is one of the main transformer fault types, making the transformer damaged when the fault is formed. The current instruments usually work by waveform comparison, or resistivity change, doing nothing for slight short circuit. The transformer windings will be effective screened when the analysis and diagnosis on short-circuit is conducted based on transformer resistance, transformer amperometry, leakage magnetic field, electromotive force, and temperature as well. |
| Keywords: | transformer turn-to-turn short circuit fault detection |
