Outdoor dry-type fully-enclosed anti-ferro-resonance three-phase voltage mutual inductor

The utility model discloses an outdoor dry-type fully-enclosed anti-ferromagnetic resonance three-phase voltage transformer. The utility model is provided with transformer bodies; a primary electric conductor leads out a primary winding of each transformer body to a primary connecting terminal, and a second connecting terminal is led out to a secondary connection box through a conducting wire. The utility model is provided with four transformer bodies, and the primary winding of each transformer body is connected through a primary conducting wire according to the principle of anti-ferromagnetic resonance; more specifically, after the primary windings of the A to C transformer bodies form three-phase star-shaped wiring connection, a primary neutral point is earthed through the primary winding of a zero order transformer body, namely, the N end of the primary winding of the zero order transformer body is earthed; after the secondary windings of the A to C transformer bodies form star-shaped wiring connection, a secondary neutral point is earthed through a basic secondary winding of the zero order transformer body, namely, the n end of the basic secondary winding of the zero order transformer body is earthed; besides, the components are sealed into an integrated structure at one time through insulating material. The utility model has the characteristics of anti-ferromagnetic resonance, stable insulation, good sealing performance, etc.
