Product overview of three-phase 200V isolation transformers for Japanese equipment

The SG-F series of three-phase dry isolating transformers for Japanese equipment are a new generation of energy-saving power transformers developed and produced by our factory on the basis of referring to similar products and combining with my country’s national conditions. The transformers range from 100VA to 2000KVA and comply with IEC439, GB5226 and other standards. The winding adopts a whole-row winding method; the transformer is vacuum dipped to make the insulation grade of the transformer reach F or H grade, and the product performance reaches the advanced level at home and abroad.SG-F series three-phase dry-type isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltages below 3300V. They are used in power supplies for equipment imported from Japan, Taiwan, South Korea, the United States, precision machine tools, mechanical electronic equipment, medical equipment, rectifiers, lighting, etc. .The various input and output voltages of the product, the connection group, the number and position of the adjustment taps (usually ±5%), the distribution of winding capacity, the secondary single-phase winding equipment, the use of rectifier circuits, whether it is required to bring The shell, etc., can be carefully designed and manufactured according to user requirements.

Product features of three-phase 200V isolation transformer for Japanese equipment

The establishment of a new neutral line-grounding in the isolation transformer can relieve the common mode interference and other neutral lines in the power grid. The isolation transformer converts the three-wire delta connection into a four-wire Yo system, and shielding further eliminates the high-frequency pulse interference coupled by the transformer. And noise, although the shielded isolation transformer can effectively prevent various NG interference (pulse and high-frequency noise), the transformer must be properly grounded and very strict, otherwise the anti-common mode interference will be ineffective.The company can design and produce high-quality isolation transformers for customers.
