Vegetable insulating oil shows good performance in electric, high anti-aging ability and environmental protection. Thus it is considered as a promising substitute for mineral insulating oil. In order to the wide spread application of vegetable oil in large power transformers, this paper presents accelerated aging experiments of oil-paper insulation involving insulating paper and the mixed oil. The...
The dielectric properties of transformer oil effects its service life,and the safety grade of distribution network. Nanoparticles have attracted much attention in recent years, because they can enhance the dielectric properties of transformer oil, and also have a wide range of potential applications. In this paper, stable nanofluid of Fe3O4 nanoparticles with different concentration in the transformer...
Phosphate removal is important to control eutrophication and adsorption is an efficient treatment process. In this paper, titanium pillared bentonite (Ti-Bent) were prepared, characterized, and its adsorption properties for phosphate were evaluated in batch experiments. The results showed that the significant increase of interlayer spacing, BET surface area and total pore volume all benefited to the...
Nitrogen removal is important to control eutrophication and adsorption is an efficient treatment process. In this paper, three modified bentonites, hydroxy-aluminum pillared bentonite (Al-Bent), hydroxy-iron pillared bentonite (Fe-Bent), and cetyl trimethylammonium exchanged organo-bentonite (CTMAB-Bent) were prepared, characterized, and its adsorption properties for ammonia nitrogen were evaluated...
