This series of five-post rectifier transformers are professional power transformers equipped with six-phase dual anti-satellite half-wave rectifiers. The core of the transformer has a five-post structure, which allows three-times three-frequency harmonic waves with the same phase in the side yoke. In a loop, the three-phase five-column core can also operate in parallel with two three-phase half-wave rectifiers in the same way as a balanced reactor. The three-phase five-column core can also pass the zero-sequence magnetic flux in the asymmetric component through the side yoke. Therefore, the structural parts loss of the rectifier chassis is greatly reduced. The three-phase five-column iron core is used to cancel the balance reactor. The high-current bus structure of the entire rectifier device is simplified, the freedom of modeling is released, and the process design is more reasonable. Save a lot of raw materials and reduce the weight of the whole machine.
Conditions of use :
This series of products is suitable for use in areas below 1000 meters above sea level. The product is installed in a rectifier cabinet. The maximum ambient humidity is + 40 ° C and the lowest temperature is -30 ° C. These series of products are self-cooled air-cooled structures. Ventilation to avoid violent vibration and harmful air and dust erosion.
This product is a five-pillar iron core structure (three core pillars and two side yokes). The cross section of the core post is a multi-stage circle. The upper and lower yokes and the side yokes are rectangular. They are stacked with high-quality silicon steel sheets. Wire-wound winding, the inner coil is cylindrical, the outer coil is multi-pie parallel, and the heat dissipation is good. The diameter of the core is more than 180, and 20 cooling air channels are added in the middle. This product has two types of insulation materials: B and F.
