Dry type transformer

Dry Type Transformer is cooled by air convection, which is generally used for local lighting and electronic circuits. For mechanical equipment and other transformers, in the power system, steam turbine transformer, boiler transformer, ash removal transformer, dust removal transformer, desulfurization transformer, etc. are generally dry-type transformers with transformation ratios of 6000V/400V and 10KV/400V, which are used for loads with rated voltage of 380V. Simply speaking, dry-type transformer refers to the transformer whose core and winding are not immersed in insulating oil.

Performance characteristics of resin insulated dry-type transformer
1. High safety: it does not support combustion, can be flame retardant, will not explode and release toxic gas, and will not cause harm to the environment, other equipment and human body during use;
2. High reliability: the product is of class H (180 ℃), while the main insulating material is of class C (220 ℃), with strong overload capacity and good short circuit resistance. Under the condition of good ventilation, 20% overload operation is allowed.
3. Energy conservation and environmental protection: steel, iron and other materials are easy to recycle; Low product loss and energy conservation; Low noise and flexible design.
4. Large capacity: 50KVA ～ 2500kVA
5. Multi function combination: from a single transformer to a multi-functional combined transformer with air cooling, protective casing, temperature computer interface, zero sequence transformer, power metering, enclosed bus and side outgoing line.
6. Multi field development: from distribution transformers to power station auxiliary transformers, excitation transformers, subway traction rectifier transformers, high current furnace transformers, nuclear power plants, marine and oil production platforms and other special transformers and multi-purpose fields.
