The selection of dry-type transformers and oil immersed transformers should be based on specific scenario requirements. The following is an analysis of their applicability:
1. Applicable scenarios for dry-type transformers
① Places with high fire prevention requirements
High rise buildings and commercial centers: dry-type transformers have significantly reduced fire risks due to their oil-free design, making them suitable for installation in densely populated areas.
Hospitals and schools have strict safety requirements, and dry-type transformers can avoid safety hazards caused by oil leaks.
② Restricted space or indoor installation
Data center and communication base station: Low noise and pollution-free equipment are required, and dry-type transformers can be arranged in the same room as switchgear to reduce the footprint.
Underground facilities and tunnels: Due to limited space and high fire prevention requirements, dry-type transformers do not require oil as a cooling medium, making them suitable for such environments.
③ Scenarios that are sensitive to environmental protection and maintenance costs
Areas with high environmental requirements: Dry type transformers have no oil pollution and meet green building standards.
Places with low maintenance requirements: Their maintenance free feature can reduce long-term operating costs.
2. Applicable scenarios for oil immersed transformers
① Large capacity, high voltage demand
Large substations and industrial parks: Oil immersed transformers have excellent heat dissipation performance and are suitable for long-term high load operation, meeting the demand for centralized power distribution.
Long distance transmission: Oil immersed transformers can effectively improve grid efficiency at high voltage levels.
② Outdoor or harsh environments
Chemical plants and mines: Oil immersed transformers can adapt to harsh conditions such as humidity and pollution, ensuring stable operation of equipment.
High humidity or high temperature areas: Their excellent heat dissipation characteristics make them more advantageous in these environments.
③ Cost sensitive projects
Scenario with limited budget: Oil immersed transformers have lower initial investment costs and are suitable for price sensitive applications.
