High-cost-performance electromagnetic compatibility isolation transformer

The utility model discloses a high cost performance electromagnetic compatibility isolation transformer which comprises a primary winding, an auxiliary winding, a first metal core and a second metal core, the primary winding is wound on the first metal core, the auxiliary winding is wound on the second metal core, and magnetic circuits between the first metal core and the second metal core are communicated. And the primary winding and the secondary winding are arranged at an interval. According to the electromagnetic compatibility isolation transformer with the high cost performance, the primary winding and the secondary winding are wound on the first metal core and the second metal core respectively, the primary winding and the secondary winding are arranged in a spaced mode, and the space distance is formed between the primary winding and the secondary winding, so that distributed capacitance between the primary winding and the secondary winding is reduced, and capacitive reactance between the primary windi
