PURPOSE: A sulfur hexafluoride (SF6) gas reduction type eco-friendly 245 kV voltage transformer for a gas insulation switchgear (GIS) is provided to slimly form the same into a cylindrical drum, thereby improving the efficiency of an installation space over 70%. CONSTITUTION: A sulfur hexafluoride (SF6) gas reduction type eco-friendly 245 kV voltage transformer for a gas insulation switchgear (GIS) for power transmission/transformation includes a transformer tank part (10), a spacer part (20), an input/output terminal part (30), and a high-voltage resistance part. The transformer tank part is formed into a cylindrical drum, and protects an inner structure from external pressure. The transformer tank part houses a hybrid insulation gas inside, the hybrid insulation gas is such that the use amount of the SF6 gas is reduced over 50%. The spacer part at one side inside the top of the transformer tank part switches the hybrid insulation gas. The input/output terminal part contacts the power source side high-voltage part of the GIS with the primary coil of a coil part, and then applies an electric current. The high-voltage resistance part detects high voltage from the power source side high-voltage part. |
