Solutions of SF6 Circuit Breaker in High-Voltage Power Systems: A Case Study of VZIMAN Company

​

1. Daidaitaccen a Tattalin Rarrabawa Da Karamin Kirkiro​

1.1 Tattalin rarrabawa da karamin kirkiro, wanda shi ne mafi girman tattalin rarrabawa, suna da daidaito masu muhimmanci:

• ​Girman Ingantaccen Farkon Zaberi: Idan an yi karfi a karamin kirkiro (misali, 500kV da kafin) zan iya ba da ingantaccen farkon zaberi (daga 40kA zuwa kafin) da abubuwan samun sakamakon gaba-gaban.
• ​Risuka ta Karamin Kirkiro: An yi karfi a cikin takalma da ke kan karamin kirkiro (misali, tsohon karamin kirkiro) zan iya haɗa da tsaya, wanda yake ya haifar da karamin kirkiro mai risuka.
• ​Yawan Samun Littafi: Harsunan adawa (misali, karamin kirkiro mai yawa, karamin kirkiro mai hankali) suna haifar da sauya na farkon zaberi, wadanda yana haifar da tsari.
• ​Karamin Kirkiro Mai Yawan Gadi: Yanayin inganta na farkon zaberi da kuma risuka na gas SF6 suna haifar da yanayin inganta mai yawan gadi da kuma abubuwan da suka haifar da tsarin al'umma.

2. VZIMAN’s Innovative SF6 Circuit Breaker Solutions​

Don samun daidaito, VZIMAN ta samun sistema mai farkon zaberi SF6 mai takaice da abubuwan teknologi:

2.1 ​Teknologi na Sakamakon Gaba-Gaban na Tsakanin​

• An amfani da tsakanin mai inganci na farkon zaberi, inda energy na farkon zaberi take haifar da gas SF6 baki daya, tare da tsayon abubuwan pump mai gaba-gaban da kuma tsayon energy.
• An amfani da fadada copper-tungsten alloy don sake haifar da farkon zaberi (12,000–14,000K), wanda ya haifar da ingantaccen farkon zaberi 50kA da kuma misali mai yawan gadi 0.1%.

2.2 Intelligent Monitoring and Environmental Optimization​

• An amfani da sensa mai microma da pressure da ZigBee technology don yanayin inganta na gas density a lokacin daidai (±0.5% accuracy).
• An amfani da current transformers na microcrystalline alloy (0.2-class accuracy) da kuma takamadduka 12 CT configurations don abubuwan da suka haifar da tsarin inganta.
• An amfani da molecular sieve da alumina adsorbents don tsayon abubuwan haifar da gas SF6 (<0.5%) da kuma HF decomposition 90%.

2.3​ Seismic Resistance and Modular Design​

• An amfani da mekanismi mai spring-operated (CT14 type) da farkon zaberi don 8-degree seismic resistance da 3,000+ mechanical operations, wanda shi ne mafi kyau don yanayin inganta daidai.
• An amfani da multi-break series configurations da voltage-equalizing capacitors, wanda shi ne mafi kyau don tattalin rarrabawa mai karamin kirkiro (750kV+).

3. Performance and Competitive Advantages​

VZIMAN’s solution complies with IEC 62271-200 and demonstrates:

• ​Enhanced Reliability: 20% lower failure rates in 40.5kV systems and 85% overvoltage suppression during capacitor switching.
• ​Reduced Maintenance: Maintenance intervals extended to 10 years, with SF6 replenishment frequency reduced by 70%.
• ​Environmental Compliance: SF6 recovery rate >99%, 50% lower global warming potential (GWP), aligning with EU F-Gas regulations.

4. Typical Applications​

• ​Renewable Energy Integration: Resolves contact welding in wind farm substations caused by inrush currents during reactive compensation.
• ​Urban Grid Upgrades: Compact designs (e.g., LW8 series) fit space-constrained substations, enabling no-reignition switching for 50km unloaded lines.
• ​Cross-Border Transmission: Validated in ±800kV HVDC projects, operating reliably in -40°C environments to ensure transnational power corridor stability.
