High - Efficiency, Simplified, Smart: Outdoor VT/PT Solutions for Installation, Commissioning & O&M
In power grid construction and refurbishment projects, the installation efficiency, commissioning accuracy, and O&M convenience of outdoor Voltage Transformers (VTs/PTs) directly impact project timelines, operational costs, and system reliability. This solution is specifically designed to optimize the full lifecycle management of outdoor VTs/PTs. Through innovative technologies and lean design, it significantly enhances the efficiency and safety of construction, acceptance testing, and O&M phases.
1. High-Efficiency Installation: Empowered by Modular & Standardized Design
- Modular Prefabrication, Reduced On-site Risk:
- Core Advantage of Gas-Insulated PTs: Factory pre-assembled and pre-filled gas-insulated PTs (e.g., GIS-style) enable "ready-to-install" deployment. Drastically reduces (>50%) complex on-site steps like gas filling and component assembly, eliminating risks associated with gas moisture treatment and sealing.
- Lightweight Design, Simplified Hoisting:
- Utilizing high-strength composite insulators instead of traditional porcelain insulators reduces equipment weight by >30%. Optimized center of gravity ensures stable and efficient lifting.
- Standardized lifting points and balance indicators. Provides standardized prefabricated foundation templates with optimized anti-settlement and drainage solutions, guaranteeing right-first-time foundations eliminating rework.
- Foolproof Design, Precise Wiring:
- Laser-etched permanent markings on critical connections. Terminal blocks clearly arranged per IEC/GB standards (e.g., dual numbering). Test terminals equipped with transparent protective covers to prevent accidental contact, enabling fast and accurate wiring.
2. Smart Commissioning: Accelerated Energization via Pre-testing & Standardization
- Comprehensive Factory Testing, Zero-Defect Delivery:
- All-parameter high-standard tests (polarity, ratio, winding resistance, dielectric loss & capacitance, power frequency withstand voltage, partial discharge, etc.) performed before dispatch. Complete data and authoritative test reports (including electronic copies) provided, offering reliable benchmarks for field acceptance.
- Efficient On-Site Verification:
- Dedicated test adapters and standardized commissioning procedures enable swift verification of key parameters like ratio and polarity, reducing acceptance time by >40%.
3. Simplified O&M: Low-Maintenance Design & Smart Monitoring System
- "Low-Maintenance" Engineering Design:
- Long-life reliable sealing technology (e.g., metal-welded seals, high-elasticity gaskets) combined with coreless structure design significantly reduces routine maintenance needs (recommended maintenance interval >10 years), lowering O&M costs by >35%.
- Facilitated O&M Access: Features tool-free quick-access oil/gas sampling valves (leak-proof design), and ground-level visible oil level/density gauges (temperature-compensated), eliminating the need for climbing or specialized equipment.
- Smart Condition Awareness & Efficient Diagnostics:
- Supports integration of high-precision online monitoring units (reserved interfaces for PD monitoring, DGA, dielectric loss, etc.) enabling real-time equipment condition alerts.
- Provides detailed step-by-step guidance manuals with graphics (including AR-guided tutorials): Covering installation, commissioning, preventive testing, condition assessment, and typical defect handling. Reduces resolution time by >30% and enhances field operation accuracy.
4. Core Value: The Efficiency vs. Reliability Win-Win
- Efficient Construction: Modular prefabrication and lightweight design compress on-site construction time by >40%, reducing safety risks.
- Accurate Commissioning: Comprehensive factory testing ensures zero-defect energization, boosting commissioning efficiency by >40%.
- Economical O&M: "Low-maintenance" design and smart monitoring reduce periodic maintenance frequency by >50%, lowering lifecycle costs by >35%.
- System Reliability: Standardized installation and precise maintenance ensure long-term stable operation, minimizing unplanned outages.
