Abstract
A three-phase dry-type transformed comprises a base, a temperature controller, an active-part insulation assembly and an iron core assembly. The iron core assembly is arranged in the active-part insulation assembly which is arranged on the base. Three point angles of an iron core structure are provided with high-voltage coil windings and low-voltage coil windings which are sequentially disposed from inside to outside and which form a three-phase balance structure. Three high-voltage terminals are uniformly disposed on each of two sides of the top of the iron core assembly. Each two adjacent high-voltage terminals are electrically connected through high-voltage leads. Two groups of low-voltage terminals are disposed on the bottom edge of the top of the iron core assembly and electrically connected through a low-voltage lead. The temperature controller is arranged on one side of the low-voltage terminals. The three-phase dry-type transformer has the advantages of capabilities that no third-harmonic does is generated, effectiveness in power saving, low heat, good radiating conditions, high level of insulation and heat-resistance, safety and reliability.
