Solusyon sa Teknolohiya: RW Series Vacuum Pressure Impregnation (VPI) Dry-Type Transformers

I. Pangunahing Pagbabago sa Teknolohiya

Gumagamit ng proseso ng Vacuum Pressure Impregnation (VPI) upang makapagtayo ng high-density epoxy resin, na nagreresulta sa solidified insulation na walang void.
Ang antas ng partial discharge ay naka-control nang maayos sa <10 pC (IEC 60076-11 standard).
Ang thermal class ng insulasyon ay umabot sa Class H (180°C), at ang rate ng pag-degrade ng performance ng insulasyon ay ≤5% sa loob ng buong lifespan.

Integrated casting at sealing technology, na nagreresulta sa IP54 protection (resists persistent dust ingress and water splashing from all directions).
Flame-retardant grade F1 (per GB/T 2207 standard testing, no sustained combustion under 900°C open flame).
Malawak na range ng operating temperature: -25°C to +40°C (no derating required in areas at ≤1000m altitude).

≥15% reduction** sa no-load losses para sa SCBH15/SCB14 series kumpara sa GB 20052 energy efficiency standard.
Measured data (1000kVA): No-load loss ≤0.40kW, Load loss ≤7.8kW.
Dynamic load loss optimization technology, achieving efficiency ≥98.5% within the 35%~100% load range.

Embedded PT100 platinum resistors in windings (IEC 60751 Class A accuracy, temperature measurement error ±1°C).
Supports Modbus RTU/TCP protocols. Enables via IoT gateway:
