Dry-type transformers SG-500kva three-phase AC transformer

SG three phase transformer (referred to as SG transformer) is a factory in the light of international similar products, combined with China's national conditions on the basis of the development and production of a new generation of energy-saving power transformers, from between 100VA to 1000KVA, in line with IEC439, GB5226 and other international and national standard windings are born out of the whole column winding method; transformer vacuum impregnation, the transformer insulation level to F or H grade, product performance reached international advanced level. Transformer series single-phase, three-phase isolation transformers are widely used in AC 50Hz to 60Hz, voltage 660V following circuit is widely used in import key equipment, precision machine tools, machinery and electronic equipment, medical equipment, rectifier equipment, lighting plant; mining industry , railway stations, docks, airports and so on. Products of various input and output voltage level, join groups, regulating the number and location of the tap (typically ± 5%), winding capacity allocation, single-phase secondary winding of the equipment, the use of rectifier circuit, is required with shell etc., it can be carefully designed and manufactured according to user requirements. Here are Shanghai Wen Feng Electric Co., edit Sun Yue lead us a brief look stable peaks SG dry-type transformers. Second, product characteristics: the establishment of a new isolation transformer neutral - ground can lift the grid common mode interference and other midline troubled isolation transformer to convert three-wire four-wire connection △ Yo systems, add shielding to further relieve the internal transformer coupling The high-frequency pulse interference and noise, although shielded isolation transformer various NG interference (pulse and high frequency noise) can effectively prevent, but the transformer must be properly grounded correctly, very strict, otherwise there will be no resistance to common mode interference effect . The company can provide customers design and production of high-quality isolation transformer. Three characteristic advantages:?? Highly isolation NG good performance is highly common mode interference rejection will be converted to Y or Y △ to △ voltage tap easily converted according to user's specific performance requirements and design four technical indicators rated input voltage????: Three-phase 380V or 380V single-phase or single-phase 220V 2 :( output voltage according to customer requirements) 3 Operating frequency: 50Hz-60Hz 4 Efficiency: ≥95% 5 temperature: <606 waveform distortion: <0.1% 7 high-pressure test: 2500V, 1 minute without breakdown 8 Insulation resistance: winding insulation resistance ≥500M European primary to secondary insulation resistance ≥500M Euro V conditions of use apply Altitude:. ≤5000m 2 Ambient temperature: -15 ℃ ~ + 45 ℃ 3 Relative humidity: ≤90% 4 installation site should not seriously affect the strength of transformer insulating gas, steam, chemical deposition, dirt, dust, and no other explosive conductive flammable and corrosive substances. 5 who do not meet the above criteria, it should only be used after Shanghai Wen-Electric consultation with. Dry-type transformers is now widely used in almost all electrical power stations, factories, hospitals and the like. With low noise (2500kVA the following distribution transformer noise has been controlled within 50dB), energy conservation (no-load loss reduced by up to 25%) SG (B) 9 Series application, making performance of Chinese dry-type transformers and manufacturing technology has reached world advanced level.
