The structure of transformer bushing

The bushing is mainly composed of capacitive core, oil pillow, flange, upper and lower porcelain sleeves, mainly insulating the capacitive core, is connected in series with concentric capacitance, sealed in the upper and lower porcelain sleeves, oil pillows, flanges and bases. In the container, there is a treated transformer oil, which makes the internal main insulation become the structure of the oil paper. The contact facial liner between the main assembly of the casing is in the oil-resistant rubber gasket, and each component is in the entire sealing state by a central compression force applied in a set of strong springs in the oil storage cabinet. The flange is provided with a flexible plug, an oil supply device, a device for measuring casing dielectric loss (TAN δ, referms), and local discharge (referred to as bureau). The outer cover of the runtime measuring device must have a cover to ensure that the last screen is grounded.

The connection between the bushing and the transformer high voltage lead has two ways of cable and guide.
