three phase double winding amorphous alloy transformer - Extremely Low Loss, Energy-Saving Features, High Power Consuming Efficiency; ã??ã??- Amorphous Metal Materials are advantageous in that: They just need to consume lesser energy in material manufacture and with their extremely low losses, power is saved in a large sum, thereby greatly reducing the power plant output, or relatively lowering waste gas (CO2, SO2) emission, lessening both environmental pollution and greenhouse effects, and realizing a maintenance free and contamination free state; ã??ã??- Low in Operating Temperature, Tardy in Insulation Aging, and Long in Transformer Life; ã??ã??- High Overload Capacity, High Mechanical Strength; ã??ã??- Amorphous Cores are featured in that: When a magnetic flux pass through amorphous cores in a rather high frequency, these amorphous cores may remain a low iron loss and a low exciting current, which may not result in core saturation. Consequently SBH15 amorphous alloy transformers made from amorphous cores possess a rather fine resistance to harmonic waves; ã??ã??- Rapid Investment Recovery

HVDC transformers are key components of HVDC stations. HVDC converter and inverter stations terminate long-distance DC transmission lines or DC sea cables. This type of transformer provides the interface between AC grids and high power rectifiers and are used to control the load flow over the DC transmission lines. These actors adapt the AC grid voltage to an adequate level which is suitable for feeding the valve system of DC converter and inverter. Design options The design concept of HVDC transformers is mainly influenced by the rated voltage, rated power and transportation requirements like dimensions, weight and mode of transportation. Many large power HVDC converter station are located in rural areas of low infrastructure. Frequently, special geometrical profiles have to be fulfilled in order to move such transformers by railway. Typically, HVDC transformers are single phase units containing 2 winding limbs. This concept can include either 2 parallel valve windings (two for delta or two for wye system, fig. 5.8-1) or two different valve windings. In order to reduce the total transportation height frequently the core assembly includes 2 return limbs. Due to redundancy requirements in HVDC stations 3 phase units are quite uncommon. The valve windings are exposed to AC and DC dielectric stress and therefore a special insulation assembly is necessary. Furthermore, special lead systems connecting the turrets and windings have to be installed in order to withstand the DC voltage of rectifier. Additionally, the load current contains harmonic components of considerable energy resulting in highe r losses and increased noise. Above all, special bushings are necessary for the valve side to access upper and lower winding terminals of each system from outside. Conclusively, two identical bushings are installed for star or delta system. For approving the proper design and quality of manufacturing special applied DC and DC polarity reversal tests have to be carried out. The test bay has to be equipped with DC test apparatus accordingly and needs to provide adequate geometry to withstand the DC test voltage. HVDC Transformers react as coupling elements between the connected AC grids and high power rectifiers, and are necessary for adapting the voltage. They insulate the rectifier itself from the AC grid and generate a phase shift. New HVDC applications are seen between existing, well-established networks. A back-to-back link can easily combine two different AC networks together, even with different frequencies. Such solutions can also help customers to strengthen and optimize their networks. The changing environment provides more and more opportunities to HVDC solutions, and Siemens is prepared to provide its customers with either our solution or with converter transformers as a loose component .

Amorphous alloy transformer Place of Origin: Shandong, China (Mainland) Brand Name: Juneng or customized Model Number: SH15 Usage: Power Phase: Three Coil Structure: toroidal Coil Number: two windings certificate: ISO9001 ISO14001 OHSAS18001 voltage ratio: 10/0.4 11/0.4 6/0.4 damp-proof method: full sealed cooling method: ONAN iron core: amorphous alloy frequency: 50 HZ winding: duplex winding Packaging Details:Main body in nude and the accessories packing in seaworthy standard wooden case or according to the requirement of customers. Delivery Detail:usually within 30 days after the deposit Description of Amorphous Alloy Transformer: Amorphous alloy transformer is a new energy-saving and environment-friendly product, recently launched by our company based on market needs.SH-15 amorphous alloy transformer is made by amorphous alloy cores. They are rolled into the shape of three-phase and five-column, thus result the height of this type of transformer is lower than the three-phase and three-column transformer. What's more, the vacuum oil injection technology greatly improves the insulation level of the transformer. Low-voltage winding generally adopts cylindrical structure by copper foil winding except a small capacity using copper wires.High-voltage winding adopts multilayer cylindrical structure, it makes the distribution of ampere-turns is balanced and the magnetic flux leakage is small. The high and low voltage coils are winded by wire tension device.They are then shaped by press-fitting, This enhances the ability of intensity and anti-short circuit. And we use the mounting plate when assembling the transformer, this increases the reliability. As for the tank structure and protector, etc, are similar to the whole sealed oil-immersed distribution transformer. Due to the special magnetic features of amorphous alloy material,the product technical performance indicators have reached the advanced level among the similar products in China at present. So it can replace the silicon steel core transformer, and be used in the distribution networks of outdoor or indoor. Meanwhile, because of the using of a fully-sealed structure, the insulating oil and insulating medium can't contact with air,So it can be operated under any environmental conditions, and is an ideal distribution equipment in urban and rural distribution networks. The no-load loss of this transformer is only about 30% of the S11 transformer with the same capacity. Compared with S9 transformer of the same capacity, the no-load loss decreases about 75%, the no-load current falls about 80%. User's operating costs can be greatly reduced, and the social and economic benefits are excellent. Advantages of Amorphous Alloy Transformer: 1.Amorphous metal transformer with alloy cores 2.High level of insulation 3.High mechanical strength, strong ability to withstand short circuit, safe and reliable operation 4.High adaptability to any environment 5.Significant energy-saving effect 6.Low noise, easy installation
