Quality Analysis of the Series Detuned Filter Reactors manufactured by Jinneng
Apr 11, 2026| I. Item-by-Item Breakdown of Core Indicators (Comparison of Both Reactors)
1. Three-Phase Reactance / Inductance Balance (Core Performance Indicator)
This is the most critical quality indicator for Series Detuned Filter Reactors, directly determining three-phase current balance, temperature rise uniformity, and filtering performance.
| Indicator | Reactor 1 | Reactor 2 | National Standard / Industry Requirement | Evaluation |
|---|---|---|---|---|
| Three-Phase Reactance (Ω) | A: 0.5546 / B: 0.5622 / C: 0.5526 | A: 0.5476 / B: 0.5558 / C: 0.5452 | Deviation of each phase from average ≤ ±2% | Both far exceed the standard |
| Maximum Reactance Relative Deviation | 1.37% | 1.53% | ≤ ±2% | Reactor 1 is slightly better, Reactor 2 is also excellent |
| Three-Phase Inductance (mH) | A: 1.7657 / B: 1.7900 / C: 1.7595 | A: 1.7441 / B: 1.7702 / C: 1.7365 | Deviation of each phase from average ≤ ±2% | Extremely high consistency between both units |
| Maximum Inductance Relative Deviation | 1.37% | 1.53% | ≤ ±2% | Both are well below the national standard limit |
✅ Analysis:
The three-phase unbalance rates of both Series Detuned Filter Reactors are far below the national standard requirement of ±2%, indicating extremely high precision in core air gap control and winding manufacturing, with perfect magnetic circuit symmetry.
The parameter difference between the two units is minimal (inductance difference of only ~1%), proving excellent production consistency and stable quality control for the same batch.
2. Active Power Loss (Energy Efficiency & Temperature Rise Indicator)
Lower loss means less heat generation, longer service life, and higher energy efficiency for Series Detuned Filter Reactors.
表格
| Indicator | Reactor 1 | Reactor 2 | Industry Conventional Level | Evaluation |
|---|---|---|---|---|
| Total Three-Phase Loss ΣP | 0.1311 kW (131.1W) | 0.1382 kW (138.2W) | 150W~200W | Both are at the low-loss premium level |
| Maximum Single-Phase Loss | Phase B: 0.0443kW (44.3W) | Phase B: 0.0505kW (50.5W) | 60W~70W | Excellent loss control |
✅ Analysis:
The total loss of both Series Detuned Filter Reactors is significantly lower than the industry average, indicating the use of high-quality low-loss silicon steel core, excellent winding insulation and assembly technology, resulting in low temperature rise and high reliability for long-term operation.
Reactor 2 has slightly higher loss, but still in the excellent range. The loss levels of both units are fully consistent, representing normal fluctuation within the same batch.
3. Voltage / Current Consistency (Auxiliary Verification)
表格
| Indicator | Reactor 1 | Reactor 2 | Evaluation |
|---|---|---|---|
| Three-Phase Voltage (V) | A: 19.275 / B: 19.550 / C: 19.325 | A: 19.169 / B: 19.429 / C: 19.185 | Highly balanced three-phase voltage for both units with no significant deviation |
| Three-Phase Current (A) | A: 34.755 / B: 34.771 / C: 34.966 | A: 35.004 / B: 34.956 / C: 35.188 | Almost identical three-phase current for both units, further verifying electrical symmetry |
II. Final Quality Conclusion
- Both Series Detuned Filter Reactors are premium qualified products: Core indicators (three-phase balance, loss) all far exceed national standard requirements, with outstanding performance.
- Stable quality control for the same batch: Highly consistent parameters between the two units prove unified production technology and material selection, with no individual variation.
- High long-term operation reliability: Low loss + high balance means uniform heat generation during operation, no unbalanced load, and longer service life, suitable for continuous long-term operation.
III. Supplementary Note
If these two Series Detuned Filter Reactors are supporting components for the same system (e.g., for parallel / series use), this highly consistent parameter performance is an additional advantage, ensuring fully balanced current and load during system operation, avoiding overheating of a single unit and uneven filtering effect.
