5. FAQ
5.1 What is the difference between 1000kVA oil immersed distribution transformer and dry-type transformer of the same capacity?
The two types of transformers differ greatly in cooling mode, application environment and operation cost. The 10Kv 1000Kva Oil Immersed Distribution Transformer adopts insulating oil circulating cooling, with better heat dissipation effect, stronger overload capacity and lower manufacturing and operation cost, which is more suitable for outdoor installation, industrial sites and large-area regional power distribution. Dry-type transformers rely on air cooling, with higher safety in closed indoor environments, but have higher cost and weaker overload resistance. For conventional outdoor power grid and industrial power distribution scenarios, oil immersed distribution transformers have higher cost performance and wider applicability.
5.2 Does this 10kV 1000kVA oil immersed transformer require frequent maintenance?
This fully sealed oil immersed distribution transformer belongs to low-maintenance equipment. Thanks to the fully enclosed corrugated tank structure, the internal insulating oil and windings are isolated from the outside air, which will not cause oil deterioration and insulation aging due to external dust and moisture. In daily use, only regular visual inspection of oil level, shell oil leakage and operating noise is required. The insulating oil can be replaced every 6-8 years in normal environment, which is far lower than the maintenance frequency of traditional open-type transformers, greatly saving manual and material maintenance costs for users.
5.3 What load range is suitable for the 1000kVA distribution transformer?
The rated effective load of this 10kV oil immersed distribution transformer is about 800kW under conventional operating conditions. In actual operation, the optimal load rate is controlled between 60% and 80%, which can balance energy-saving effect and equipment service life. It can bear short-term 110% overload operation, but long-term full-load or overload operation is not recommended to avoid accelerating insulation aging. Users can reasonably configure the transformer according to the actual peak load and daily average load of the project to ensure stable and efficient operation of the power distribution system.
