products information:
SWT Series three-phase synchronous brushless generators, are our company new products, which are basis on the internationally advanced technology. The products draw on the world's largest electrical machinery manufacturers' successful experience of using a number of their own innovative technology, such as insulation, ventilation, base structure, materials and surface treatment, etc., optimizing the design. Therefore, generator power density, efficiency, center high dimensions, as well as electrical, mechanical properties, are up to the world advanced level.
The generators meet the requirements of JB/T10747-2007, and the relevant section of other international standards, such as International Electrotechnical Society IEC60034-22: 1996 "Reciprocating internal combustion engine driven alternator", GB755 Chinese rotary motor general technical conditions and BC5000 and North America NEMA MG1-22.
products character:
1. Optional auxiliary winding or phase-compound excitation system can provide the ability of bearing short-circuit current
2. Optional permanent magnet generator system can provide a constant excitation in any condition.
3. Advanced automatic voltage regulator system can guarantee the genrator work normally even in the worst conditions.
4. Reorganization the first twelve terminal block wiring to fit the different voltage requirements.
5. Standard 2 / 3 pitch windings curbed excessive midline current, making it very easily to operate with other generators in parallel.
6. Unique overall design of salient-pole rotating magnetic field, taking into account the advantages of separation of salient-pole and hidden structure, and improved the thermal conditions and the winding coil increased mechanical strength.
7. Easy installation, convenient maintenance, with easily operated terminal, rotating diodes and the bolt axis.
8. Both of the single and full pivot type structures, in compliance with all the leading diesel engine land assembly interface standards.
9. Adopted a completely continuous damper winding and the 2 / 3 pitch windings effectively inhibit the output voltage waveform distortion and greatly reduce telephone harmonic factor and telephone interference factor.
electrical performance:
voltage sinusoidal waveform distortion rate:≤5%,
telephone harmonic factor （THF）：≤2%,
telephone interference factor（TIF）：≤50
Note:
1. Under the following conditions, the generator could run continuously at the rated voltage:Ambient temperature ＜40℃, altitude ＜ 1000m, relative air humidity ＜ 90%.
2. According to the user's need, we also can make other voltage range.
