Oil-immersed transformer has strong short-circuit resistance

Oil-immersed transformer vacuum oil filter and oil injection molding process, so the internal moisture is reduced to a low level, prevent oxygen and moisture insulation degradation caused by the entry, significantly reduce transformer maintenance costs, while extending the life of the transformer. oil immersed transformer in the occurrence of short road stone, there are current and make the winding deformation, will also produce a short circuit on the shell shell, short road stone, generally gas protection device action and grounding protection action, with copper foil winding drum structure; The high-voltage winding adopts multi-layer cylinder structure, which makes the ampere-turns distribution of the winding balanced, small leakage magnetic field, high mechanical strength, and strong short-circuit resistance. Oil-immersed transformers have been reformed and developed by the traditional form in the main direction of cleaning and protecting the environment and saving energy.

 

The oil-immersed transformer tank is filled with transformer oil and relies on the assembly's oil-resistant rubber pressure seal fasteners. Sealing is the main reason for transformer oil leakage, it should pay special attention to the maintenance and repair of transformer high voltage equipment, to maintain its good insulation performance. Oil-immersed transformers are susceptible to moisture, which is one of the main measures to be taken to prevent transformer impact and moisture maintenance.
