Repair of three-phase power transformers - oil and dry - current and capital.
Types of repaired transformers:
oil - TM, TMZ, TMG, TMF, TMR, TSMA;
dry - TPMS, TSSI, TSSU.
Types of jobs, their short list.
Diagnostics - with the lifting of the active part, or without it (in the second case, the possible departure to the place of installation of the transformer):
inspection of the outer nodes of the transformer;
check the insulation resistance of the transformer;
inspection of the switch and the active part;
sampling oil.
Current preventive maintenance - with the lifting of the active part, or without it (in the second case, the possible departure to the place of installation of the transformer):
partial drainage of the oil (to access the insulators and control devices) or full (if the replacement or regeneration);
regeneration (drying and cleaning) of transformer oil or its replacement;
disassembly and inspection of the exterior nodes of the transformer, the opening of the upper cover;
cleaning, tightening and adjustment of the switch, or replace it if necessary;
cleaning, lifting pins and threaded connections of the active part;
replacement of insulators and pins if necessary;
changing the seals on the inputs of the transformer and the top cover, and radiators as needed;
replacement of silica gel;
filling or refilling oil, selection of an oil sample for analysis;
schema validation and groups of compounds, checking insulation resistance of the transformer;
test the power transformer;
the Protocol tests.
Overhaul with change or repair (rewind) windings or without them:
Without changing or repair of windings:
disassembly and inspection of the exterior nodes of the transformer, the opening of the upper cover;
an examination of the internal nodes of the transformer, a damage report;
sampling the oil, drain and analysis;
regeneration of transformer oil or its replacement;
cleaning the interior and exterior surfaces of the radiator and tank, welding cracks, edit dents;
replacement seals radiator, top cover and bushings of the transformer;
wash, rinse active part of the transformer;
the wire insulation of bends;
the lift pins and threaded connections of the active part;
cleaning, tightening and adjustment of the switch, or replace it if necessary;
drying of the active part of the transformer;
check schemes and groups of compounds, checking insulation resistance of the transformer;
installing the active part of the transformer tank;
replacement of silica gel;
installation of HV and LV, attachments. Fill oil;
the coloration of the transformer;
test the power transformer;
preparation of the test report;
With the change or repair (rewinding) of the windings (plus the above):
disassembly of the active part;
removing the HV and LV coils, inspection winding wire;
restoring magnet wire or replace it if necessary;
the winding of the HV and LV coils;
cleaning or replacement of the magnetic circuit;
installation of HV and LV coils, a base isolation;
Assembly of the magnetic circuit, a test of his isolation;
check schemes and groups of compounds;
Assembly diagrams (welding and soldering of wires; installation of studs and switch).
Work on the modernization of transformers:
the VL of the power transformer 10 kV 6 kV;
upgrading switch - from 3 to 5 positions NR (this will allow you to better adapt to the HV network and, consequently, to reduce no-load losses of the transformer).
Warranty work performed 12 months.
