Product Descriptions
Structure features
Our company imported and absorbed internationally advanced technique and launched this international advanced combined transformer which owns exclusive internationally patent right .And the technique of product has reached the international advanced level.
Combined transformer is used to separate protection and measurement equipment the form high voltage system and change measured current and voltage into suitable current and voltage which are suitable for protection and measurement equipment with reasonable accuracy class.
This combined transformer is designed and manufactured based on IEC 60044-3. It is outdoor oil immersed combination transformer. It is the best combination product which formed by optimized configuration of current and voltage transformer units, and voltage unit structure is the same as VPU voltage transformer, and current unit structure is the same as AGU current transformer.
Main technical advantages
•The volume of the combined transformer may occupy a small space combined transformer has a small capacity which is slightly bigger than current transformer at the same voltage level.
♦Its voltage unit with open core can avoids the ferromagnetic resonance phenomenon.
♦Primary winding of voltage transformer distributes along insulator height direction and make the voltage optimum distribution along transformer vertical direction . so the product can save space.
♦Put the voltage transformer core and winding in cylinder porcelain shell to make uniform distribution of inside weight of transformer, so as to raise mechanical stability of product.
•This combination transformer has the similar manufacture and assembly techniques as inverted current transformer to make the high voltage level product manufacture to be easier.
•Adoption of combined transformer will reduce space of substation and low down investment of substation, therefore, it is the ideal selection for high voltage substation.
