Solusyon sa Voltage Transformer: Dedicadong Solusyon para sa Compact Medium Voltage Switchgear

Core Positioning:​​ Nagbibigay ng high-performance, ultra-compact na solusyon sa pagsukat ng voltage para sa medium voltage switchgear (e.g., KYN28) na may severely limited na espasyo, nakakamit ang installation flexibility na hindi makakamit ng traditional designs.

​Technical Approach: Ultra-Small Space Adaptation​
Ang mga tradisyonal na Voltage Transformers (VTs) ay malalaki at mahirap i-fit sa instrument compartments ng modernong compact switchgear tulad ng KYN28. Ang solusyon na ito ay nakakamit ang revolutionary miniaturization sa pamamagitan ng mga sumusunod na innovations:

1. ​Structural Innovation - Extremely Compact Physical Design​
• ​Dry-Type Epoxy Resin Cast Structure:​​ Ginagamit ang advanced integral casting technology, na may insulator diameter na Φ90mm, nagseset ng industry-leading limit para sa radial dimensions.
• ​Three-Phase Common-Enclosure Design:​​ Breakthrough integration ng A/B/C three-phase voltage sensing units sa isang single sealed enclosure, na in-optimize ang overall dimensions sa 250mm (L) × 180mm (W) × 120mm (H), completely eliminating redundant inter-phase space.
• ​C-GIS Dedicated Amorphous Alloy Core:​​ Ginagamit ang specially developed amorphous alloy core para sa Compact Gas-Insulated Switchgear (C-GIS). Ang materyal na ito ay nagbibigay ng mataas na permeability, mababang iron loss, at excellent temperature stability, na nasasapat sa measurement accuracy requirements sa loob ng extremely small volume – ang core material foundation na nag-eenable ng ultra-compactness.
2. ​Electrical Performance - High-Standard Reliability Assurance​
• ​Rated Voltage:​​ 12kV (Suitable for mainstream MV systems)
• ​Insulation Strength:​​
• Power Frequency Withstand Voltage: 42kV / 1min (Far exceeding standard requirements)
• Creepage Distance: ≥ 25mm/kV (High pollution flashover resistance, suitable for harsh environments)
• ​Low Partial Discharge:​​ Partial Discharge Level < 5pC (Extremely low level), ensuring high long-term operational reliability and lifespan, meeting stringent power grid equipment condition monitoring requirements.
• (Other key parameters such as accuracy class, rated burden, etc., to be specified based on application)
3. ​Core Advantage: Transformative Space Savings​
• ​Volume Reduction ≥ 60%:​​ Nakakamit ang over 60% volume compression kumpara sa traditional split-core o larger common-enclosure VTs, reaching top industry standards.
• ​Seamless Integration into KYN28 Cabinet:​​ Maaaring direktang i-install sa instrument compartment ng mainstream switchgear tulad ng KYN28, eliminating the need for extra space expansion or cabinet structure modifications. Solves the critical pain points of traditional VTs being too large to fit inside or requiring valuable space in cable/breaker compartments.
• ​Simplified Installation & Maintenance:​​ Ang single integrated device ay greatly simplifies wiring and installation processes, reducing operational complexity.
