Industry Pain Points and Challenges
Gas-insulated switchgear (GIS) voltage transformers (VTs) serve as core monitoring components in modern power grids due to their high reliability. However, their demanding high-voltage insulation structure presents significant challenges that cannot be ignored:

High Initial Investment: The procurement and installation costs of GIS-VT equipment impose substantial pressure on project budgets.
Hidden Cost Black Hole: Dedicated spare parts are expensive with long procurement lead times. Power outage losses and emergency repair costs caused by sudden failures often exceed expectations.
O&M Efficiency Bottleneck: Traditional GIS tank-opening maintenance procedures are complex and time-consuming. Unplanned downtime significantly impacts grid operating economy and reliability.

Innovative Solution: Building a Long-Term Value-Centric Assurance System
To systematically reduce the Whole Lifecycle Cost (LCC) of GIS voltage transformers, we introduce an LCC optimization solution integrating innovative services and product design:

"Equipment-as-a-Service" (EaaS) - 20-Year Comprehensive Assurance Package:

Core Service: Moving beyond traditional buy/sell models, we offer long-term contractual services covering main equipment, built-in intelligent sensor systems, and critical spare parts (e.g., coil assemblies).
Proactive Health Management: Integrated remote expert diagnostic platform leverages sensor data for real-time monitoring of insulation gas condition, electrical characteristics, and mechanical performance, enabling predictive maintenance to accurately prevent failures.
Value Core: Converts high upfront investment and uncontrollable O&M costs into predictable, long-term, smoothed service expenditures, enabling clearer and more efficient financial planning.

Standardized Modular Design - Breakthrough in Rapid Maintenance:

Core Component Standardization: Deeply decoupled design achieves high physical and electrical interface standardization and modularity for key components (e.g., core coil assemblies).
Revolutionary On-site Replacement: Under strict process guarantees, key modules can be replaced without requiring the complete dismantling of the GIS busbar enclosure. On-site maintenance time is strictly controlled within 4 hours.
Value Core: Dramatically compresses unplanned downtime, minimizes economic losses and social impact caused by grid outages, and significantly reduces capital tied up in spare parts inventory.

Expected Benefits: Quantifiable Long-Term Value Enhancement

LCC Reduction ≥ 18%: Significant comprehensive cost reduction achieved through servitization of equipment, maintenance efficiency improvements, and proactive fault prevention.
Investment Payback Period Shortened to ≤ 8 Years: Sharp reduction in O&M costs coupled with improved operational reliability substantially accelerates investment recovery, highlighting economic benefits.
Failure Loss Reduction ≥ 60%: Dual guarantees of predictive maintenance + rapid module replacement drastically reduce unplanned outage losses caused by voltage transformers.
Grid Availability Leap: Provides critical equipment support for building highly resilient and highly reliable smart grid infrastructure.
