Product Details

SF6 gas insulated current transformers, High voltage current transformer,  gas insulation current transformer, SF6 CT

36…765kV  LVQB- series
The current transformer is SF6 gas insulation, inverted frame, with the top of T type aluminum case which there are secondary winding(s) and primary winding(s) inside. The bushing is composite materials with silicon rubber umbrellas or high strength porcelain. The secondary terminal leads which through the metal tube are connected with the secondary terminals box which at the base. There is a pressure relief device at the top of the case, when the pressure is more than 0.65MPa (0.8 MPa only for 500 kV) if the current transformer is discharge inside, the relief device will be broken to release the pressure and send an alarm information. There is a SF6 density monitor fix at the base, it can indicate the SF6 pressure which inside the current transformer (its indicated value is the SF6 pressure at 20℃), and it will provide an information when the SF6 pressure is drop down to the minimum service pressure of the current transformer, to remind the user replenish the SF6 gas to the rated pressure.
