Energy-saving dry-type transformer is one of the important equipment in the power generation, transmission, transformation and distribution system. Its performance and quality are directly related to the reliability and operating efficiency of the power system operation.
Energy-saving dry-type transformers have been produced in my country since the late 1950s due to their simple structure, easy maintenance, fire prevention and flame retardancy, but mass production has only begun in the past 10 years. There are many types of dry-type transformers, mainly including impregnated insulated dry-type transformers and epoxy resin insulated dry-type transformers. With the continuous development, innovation and large-scale promotion and application of dry-type transformers in our country, dry-type transformers are expected to further develop in the future. There are still many issues worthy of study. The introduction and development of new materials, new processes, and new technologies such as low-loss silicon steel sheets, stepped core joints, foil winding structures, in-depth noise research, environmental protection requirements, and computer optimized design will make the future of dry-type Transformers are more energy efficient and quieter. The main insulation of dry-type transformers often uses the same insulation structural parts as oil-immersed transformers: insulating paper tubes, corner rings, component partitions, etc. When designing the insulation of dry-type transformers, in addition to ensuring the insulation strength, special attention should be paid to ensuring that there are sufficient air cooling ducts between coils. And attention needs to be paid to the placement of insulating parts to ensure that air can contact the coil smoothly. When purchasing dry-type transformers, you must also choose a reliable manufacturer, so as to ensure the quality and service life of the equipment. The quality of the dry-type transformers produced by our factory is guaranteed. You are welcome to call us at any time for consultation.
