02 · CHALLENGES
Business Challenges
Multiple Blind Spots in Substation Equipment Status Monitoring
Substation secondary circuit, distribution cabinet, auxiliary electrical equipment lack online monitoring means, equipment degradation and hazards hard to early detect, passive O&M mode affects power supply reliability.
Manual Inspection Low Efficiency, High Risk
Manual inspection in substation high-voltage environment has safety risks, inspection cycle is long, coverage is limited, some remote substations have high inspection costs and slow response.
Electrical Fire Hazard Hard to Early Warning
Distribution cabinet cable joint overheat, poor contact and other hazards if not detected in time, easily evolve into electrical fire, affect substation safe operation, traditional temperature inspection hard to continuous monitoring.
Data Isolated Island Affects O&M Decision
Existing monitoring systems are dispersedly deployed, data formats are heterogeneous, lack unified platform aggregation, O&M decisions rely on manual experience, lack data-driven auxiliary decision capability.
