Mbinu ya Teknolojia: Viti vya Transformer Wa Kiwango cha VPI (Vacuum Pressure Impregnation) Cha RW Series
Technical Solution: RW Series Vacuum Pressure Impregnation (VPI) Dry-Type Transformers
I. Core Technological Innovations
- Defect-Free Insulation System
- Hutumia mchakato wa VPI (Vacuum Pressure Impregnation) kutengeneza resin ya epoxy yenye ukasi mkubwa, kufikia insulation isiyonayo vipi.
- Mipango ya partial discharge zinazokontrolwa kwa uhakika katika <10 pC (kulingana na chanzo cha IEC 60076-11).
- Daraja la joto la insulation linafikia Class H (180°C), na mara ya degradation ya ufanisi wa insulation ni ≤5% kwa muda mzima wa umri.
- Robust Environmental Adaptability Structure
- Tecnologia inayofanikiwa ya casting na sealing, ikifanya IP54 protection (ingekuwa inaweza kuzuia msingi wa chochote cha viti na maji kutoka kila upande).
- Flame-retardant grade F1 (kulingana na mtihani wa GB/T 2207, hakuna moto unaoendelea kupungua wakati anapoenda kwenye mapaa ya 900°C).
- Urefu wa joto wa kazi: -25°C hadi +40°C (hakuna derating yanayohitajika kwenye maeneo yenye uwingu ≤1000m).
- Energy Efficiency Optimization Design
- ≥15% reduction** ya losses za no-load kwa SCBH15/SCB14 series kilingana na standard ya energy efficiency ya GB 20052.
- Data iliyopimwa (1000kVA): No-load loss ≤0.40kW, Load loss ≤7.8kW.
- Tecnologia ya optimization ya load loss, ikifuataji ufanisi ≥98.5% kwenye mzunguko wa 35%~100% load.
- Intelligent Maintenance System
- PT100 platinum resistors vilivyowekezwa (IEC 60751 Class A accuracy, takribu ya temperature ±1°C).
- Inasupporta Modbus RTU/TCP protocols. Inafanya kwa njia ya IoT gateway:
- Kuamini temperature ya hot-spot ya winding kwa muda wa kila wakati.
- Tathmini ya unbalance wa three-phase.
- Tathmini ya ufanisi wa energy kwa dynamic load-rate.
