ÒÌÃ TRNSFORMERS ÒÌÃ three-phase oil transformers are intended for transforming of electric energy in networks of power systems and in energy consumer networks. Transformers are designed for indoor or outdoor installation under conditions of moderate (+ 40 o C to - 45 o C) or cold (+40 o C to -60 o C) climate. Transformers are assigned for operation in inexplosive environments excluding dust content that could affect transformer parameters to inadmissible limits. Transformers are not assigned either for operation under jolting, vibration, or impact effects, or in chemically active environments. Operable altitude elevation above sea level is not more than 1000 m. ÒÌÃ 1250. Rated frequency: 50 Hz. Voltage regulation within ±5 % range is carried out with a fully de-energized transformer (power-off changing) through HV tap-changing in 2.5 % steps. ÒÌÃ transformers are of a sealed version, they have no conservators. Temperature induced changes of oil volume are neutralized due to volume changes in goffers of the tank owing to their flexible deformability. For oil-level control transformers are fitted with float-type oil indicators. To prevent excessive pressure in a tank over permissible value the 16 to 63. transformers are equipped with release valves. For control of inner pressure in a tank and for signalling in the event of inadmissible overpressure the indoor transformers of 100. and higher ratings are fitted with electrocontact vacuum manometers (option). To make measurements of top oil temperature a pocket for liquid-filled thermometer mounting is provided on the transformer cover. To measure top oil temperature and to control external electric circuits the 1000. transformers are fitted with manometric signalling thermometers (option). Transformers of 160. and higher ratings are equipped with carrying rollers for transformer moving (option). here resettable rollers are provided as an option H, H 1 sizes in 160 to 400. transformers (see Table) are increased by 94 mm.
