Abstract

With the development of high reliability operation of distribution network

on-line operation device is one of the necessary tools for operation and inspection of distribution network. Power capacitor is the core unit of energy storage for distribution unit and AC/DC power conversion unit in on-line operation device of distribution network and its high performance

light weight and miniaturization are the key to its development. For preparing the dielectric material for power capacitor with the novel high-energy storage density

the Ba(Sn

（BTS）thin films are prepared on the Pt/Ti/SiO

/Sisubstrate by magnetron sputtering technology. The crystallization and surface morphology

the dielectric constant

breakdown voltage and energy storage density of BTS film with different substrate temperature are studied and analyzed respectively.Furthermore

the relationship between the micro-structure and the energy storage performance is established. It is shown by the study that BTS film prepared at 650 ℃ has the best crystal condition

the largest dielectric constant

the highest breakdown field strength and energy storage density. The energy storage density reaches about 19.0 J/cm

which is 6 times higher than that of the current commercial polypropylene energy storage films.
