The Probe of Dry-type Transformer’s Theory and Technical Design
Abstract
In the whole power system, the transformer is a very important part. In the late of 90s, the distribution transformer industry developed fast in China. The dry type transformers has such features as simple structure, easy maintenance, fire flame and so on. From the late 50s of 20th century, the dry type transformers have been produced, but until in nearly 10 years they are high-volume production. After reform and opening up, with achieved positive results of scientific and technological research, technology introduction, digestion and absorption of technological innovation of transformers, it has played an active role in the control of various types of manufacturing technology, improving product performance, and product quality, shortening product development cycles, expanding product yield and increasing product variety.
To grasp the transformer design concept is necessary. This article involves the data collection and analysis and the basic introduction of transformer, and even make the 1000kVA resin insulation dry-type transformer as an example to explain electromagnetic calculations, the impact strength of short circuit calculation and verification. Meanwhile, the test of transformer is also very important.
This design incorporates a more advanced technology, referencing the other running transformer design information, and try the best efforts to be safe and reliable electricity supply and energy conservation.
