Fundamentals of Partial Discharge in Transformer
Partial discharge in transformer assets represents localized electrical breakdown within insulation systems that does not completely bridge the electrodes. These microscopic breakdowns occur in voids, ひび割れ, or at interfaces within the insulation where electric field strength exceeds the local dielectric strength, creating potential failure points that progressively degrade insulation integrity.
理解 Partial Discharge in Transformer システム
Partial discharges represent a critical indicator of insulation health in transformer systems, as they:
- Occur Before Complete Failure: PD activity typically begins months or years before complete insulation breakdown
- Cause Progressive Damage: Repeated discharges create carbonized tracking paths that gradually reduce insulation strength
- Generate Multiple Signals: PD events produce electrical, 音響, and electromagnetic signals that can be detected
- Indicate Specific Defects: The pattern and characteristics of PD signals reveal specific types of insulation defects
- Accelerate Over Time: As insulation degrades, PD activity typically increases in frequency and magnitude
これらを理解する この特性により、高度な検出および診断システムの開発が可能になります。 致命的な故障につながる前に、進行中の絶縁問題を特定します.

| 放電タイプ | 発生場所 | 特徴 | 検出の課題 |
|---|---|---|---|
| 内部放電 | 固体絶縁体内の空隙 (紙, プレスボード) | 通常の PD パターン, 比較的安定した位相関係 | 周囲の絶縁体による信号の減衰 |
| 表面放電 | 断熱面, 沿面経路 | 非対称パターン, 汚染に敏感 | 放電パターンに対する環境の影響 |
