Slim형 이상용 절연구분장치 개발

초록

The insulation material of the section insulator used for the isolation of different phases and for the AC/DC connection part is fiber reinforced plastics with fiberglass impregnated in the thermosetting resin. The insulation material needs frequent check-up and maintenance due to wear by pantograph and contamination, which causes the problem of the short life time. Accordingly, the authors first developed the AC/DC section insulator for different phases, which had 2 strings of insulators, using teflon tube insulation material made of teflon material with better electrical and abrasion characteristics charged with fiberglasses in order to improve the said characteristics
