Oil-immersed conservator tank transformer
|Method of cooling the windings||Oil|
IntroductionEmploys the latest technology with high quality enamel coated copper conductor windings utilized in both sides of the coil. Transformer mineral oil is used as an electrical insulation and to assist in heat dissipation inside the transformer tank. A conservator tank is installed to accommodate the expansion of the transformer mineral oil which makes this transformer design suitable for large, higher capacity (kVA) transformers which use higher volumes of transformer mineral oil. Air in the conservator tank is allowed to escape or be re-introduced to maintain transformer tank pressure equilibrium via a dehydrating breather - a filter where a combination of silica gel and transformer mineral oil traps moisture and dust. High efficiency ventilating radiator fins are attached to the transformer tank which can bear the heavy weight of the transformer mineral oil. The transformer is also equipped with standard protection equipment such as a Buchholz Relay (a gas and oil actuated safety device which detects and warns of transformer faults), a Thermometer (which detects and warns of excessive temperature increases) and a Pressure Relief Valve (which releases excessive pressure build-up inside the transformer tank to prevent the transformer tank from being deformed).
