BLACK SEA GROUP POWER TRANSFORMERS

The design and manufacture of the transformers is such that the noise level is minimum and that the level of vibration does not adversely affect any clamping or produce excessive stress in any material. Noises levels shall are in accordance with IEC 60551. The maximum acceptable level is 88 dB in conformity with NEMA std.TR-1. MAGNETIC CIRCUITS The core is “core” type, with 3 parallel legs, made of high grade, non-aging electrical cold rolled grain oriented silicous steel laminations loss and high permeability. The yokes and legs are securely held by means of synthetic resin impregnated glassfiber strips. The core is clamped both at the top and bottom by means of clamping structures of steel. The structure placed on the same side are stiffened between each other by means of tie rods made of nonmagnetic alloy. The structures on the HV and LV sides are clamped between each other by means of clamping frameworks. The live part(core winding) is centered on the tank bottom by means of four guinding cones. Within the construction described above, the live part movement during shipping and installation or while in service is fully avoided. Particular care is taken to secure even mechanical pressure over the whole of the core laminations. Under steady overvoltage condition the maximum flux density not exceed 1,9 Tesla and the magnetizing current not exceed 5 % of the rated load current at normal rated voltage. WINDINGS. The winding are circular coil concentrically type. The windings shall be formed using high quality electrolytic copper conductor, insulated with pure cellulose paper. The main insulation between windings is of the multi-duct type with cylinders made of high dielectric strength transformer pressboard. The windings and connections are braced to withstand shocks, which may occur during transport or due to switching or other transient conditions during service.

The plate thickness for the tank sides is of 10 mm. The cover is clamped to the tank, by screw fastening. The tank is provided with lugs, boses and hooks to enable the transformer, complete with all tank mounted accessories and filled with oil, to be lifted by powerhouse crane and pulling the transformer in 2 orthogonal directions. The wheels are suitable for a standard track (1.435 metre between inside of rail heads) for moving the transformer in 2 orthogonal directions. Four jacking pads are provided on the tank to enable the transformer, complete with oil, bushings and fittings,to be raised or lowered by jacks. Means are provided for locking the swivel movement in positions parallel to and at right angles to the longitudinal axis of the tank. The wheel loading does not exceed 13,000 kg . Tank covers shall not permanently distort when lifted. Inspection openings of ample size shall be provided to give easy access to bushings for changing ratio, or winding connections, and for testing the earth connections. The tank cover is fitted with a thermometer pocket, with captive screw cap, located in the position of maximum oil temperature at continuous maximum rating. Facility the bushing remove without removing the tank cover. A pressure relief device is provided for the rapid release of any pressure that may be generated within the the tank. The device operates at a static pressure of less than the hydraulic test pressure for transformer tanks and prevents further oil flow from the transformer following its operation. In the event that the device is a spring operated valve type it shall be provided with one set of normally open contacts, which will be used for tripping purposes.
