We can design and manufacture two sets of secondary windings with phase differences of 30C, 15C, and 7.5C for six phase and twelve phase rectifiers for users.

Usage environment

● Environmental temperature -30C -+40C;

● Annual average temperature of 20C or above (for water-cooled products, the cooling water temperature is taken as the daily average+25C);

● For users in high-altitude areas with an altitude of 1000m, please specify in the order. This product can meet the requirements of users with an altitude below 400m;

The installation site is free from severe vibration, bumps, and chemical corrosion, and can be used indoors or outdoors.

Product features

The rectifier transformers produced by our company are designed according to national industry standards and different production equipment processes, with low losses, high production efficiency, and reliable operation. Specifically, as follows:

In addition, transformers can also be divided into main regulating common box type and main regulating sub box type, as well as internal saturated reactors, balanced reactors and external saturated reactors, balanced reactors and other structures. In summary, our company produces a wide variety of rectifier transformers, and can design and manufacture transformers of various structural types according to the various requirements of users.

Internal structural characteristics

The iron core is made of high-quality cold-rolled silicon steel sheets. In larger transformers, in order to reduce no-load losses, the iron chip adopts fully inclined seams. The overall structure of the iron core adopts advanced technology introduced.

The grid side coils mostly adopt a continuous structure, the voltage regulating coils mostly adopt a layered structure, and the valve side coils are generally double cake structures. Due to the use of electronic computers to calculate the impact characteristics of power plants and coils

Performance enables the coil structure to have excellent electrical characteristics and impact resistance.

For larger transformers, the oil tank adopts a folding structure, which not only has a beautiful appearance but also greatly improves the mechanical strength of the oil tank.

The valve side outlet has both box top outlet and box wall outlet, making it convenient to connect with the rectifier device.

The outlet terminals on the valve side of the transformer are made of epoxy casting to form low-voltage conductive rods, making the appearance of the transformer beautiful and compact.

The transformer is equipped with various protective devices such as thermometers, gas relays, pressure relief devices, and transformers. For high-voltage products, a diaphragm type oil storage tank is used to ensure the safe and reliable operation of the transformer.
