COMBINED INSULATION SWITCHGEAR CAPABLE OF REPLACING AN EXISTING SF6 GAS INSULATED SWITCHGEAR

摘要

PURPOSE: A combined insulation switchgear is provided to use solid matter, air, and N2 gas as insulating medium in order to solve a problem in existing technologies, thereby providing the combined insulation switchgear in order to replace an existing SF6 gas insulated switchgear.;CONSTITUTION: A combined insulation switchgear(100) receives power through a cable line(110). A cut-off device(120) is included in the combined insulation switchgear. The cut-off device blocks the power when an abnormal current more than a normal current is flowing in the combined insulation switchgear. The cut-off device includes first and second bus line devices(130,140) as a kind of a distributer which is distributing electricity. A controlling board(150) includes a plurality of control apparatus which is operating by being connected to the first and second bus lines devices. The cut-off device insulates a cut-off apparatus as a solid insulation method in order to improve productivity.;COPYRIGHT KIPO 2012
