Abstract

In recent years, the companies of electric power equipment for MV and HV classes trend to develop the eco-friendly insulated(solid, eco-gas, air etc.) switchgear which replaces existent SF6 gas insulated switchgear due to environmental problems such as global warming and so on. This paper makes reference to the newly developed Solid Insulated Switchgear (SIS) which uses the eco-friendly material such as epoxy for insulation. The insulation of the solid insulated switchgear (SIS) is composed of an epoxy, vacuum and air. The solid insulated switchgear (SIS) is a slate of the art product. The advantages of SIS are advanced reliability, economical efficiency, safety, maintenance free, reduction of installation area and the protection of environment. The solid insulated switchgear (SIS) is FE Analyzed such as electromagnetic, mechanical, thermal and fluid in order to find the optimal design. Thens SIS has been verified by international standard test. (IEC 62271 - 100 and so on.) As a result of this, the solid insulated switchgear (SIS) has been estimated as an alternative for eco-friendly MV class switchgear.
