SG series three-phase dry-type marine transformer is a new generation of energy-saving marine transformer developed and produced by our factory with reference to similar products and in combination with China's national conditions. It is between 300VA and 1600KVA and conforms to iec439, gb5226 and other national standards. The winding adopts the method of whole train winding without tire; The transformer is vacuum impregnated to make the insulation grade of marine transformer reach grade f or h, and the product performance reaches the level at home and abroad. SG series three-phase dry-type marine transformers are widely used in circuits with AC 50Hz to 60Hz and voltage below 660V. They are widely used in imported important equipment, precision machine tools, mechanical and electronic equipment, medical equipment, rectifier devices, lighting, etc. Various input and output voltages, connection groups, number and position of regulating taps (generally ± 5 percent ), distribution of winding capacity, allocation of secondary single-phase winding, application of rectifier circuit, whether shell is required, etc. of the product can be carefully designed and manufactured according to the requirements of users.
Establishing a new neutral grounding in the marine transformer can relieve the problems of common mode interference and other neutral lines in the power grid. The isolation transformer converts the three wire △ wiring into a four wire yo system, and the shielding further eliminates the high-frequency pulse interference and noise coupled inside the transformer. Although the shielded isolation transformer can effectively prevent various N-G interference (pulse and high-frequency noise), the transformer must be properly grounded, Very strict, otherwise the anti common mode interference will have no effect. The company can design and produce high-quality isolation transformers for customers.
