Container type substations require special attention to prevent moisture accumulation, which can lead to equipment corrosion, insulation degradation, and electrical faults. Key protective measures include:
Structural Sealing
Ensure all door seals, cable entries, and ventilation openings are properly weatherproofed
Regularly inspect and maintain sealing gaskets to prevent water ingress
Climate Control Systems
Install dehumidifiers or air conditioning units to maintain optimal humidity levels
Use moisture-absorbing materials like silica gel in electrical compartments
Ventilation Management
Implement passive ventilation with moisture barriers to allow air circulation while blocking humidity
Consider forced ventilation with humidity-controlled fans in high-moisture environments
Installation Considerations
Elevate the container type substation base to prevent ground moisture absorption
Ensure proper drainage around the installation site
Monitoring and Maintenance
Install humidity sensors with alarm systems for early detection
Schedule regular inspections of electrical components for moisture signs
Immediately address any condensation accumulation inside the enclosure
Material Selection
Use corrosion-resistant materials for structural components
Apply protective coatings to vulnerable metal surfaces
By implementing these moisture protection strategies, operators can significantly extend the service life and maintain the reliability of container type substations in various environmental conditions.
