a, Farady oil immersed transformer low-voltage windings except for small-capacity copper wire, generally used copper foil around the pumping cylinder structure; high voltage winding cylindrical multi-layer structure, so that the winding ampere-turns of the distribution of the balance, magnetic flux leakage small, high mechanical strength, resistance to short-circuit capacity.
b, core and windings each adopted tightening measures, the fastening portion is tall, with a low-voltage wiring, etc. are self-locking lock nut, using a no hanging heart structure can withstand transportation Britain earthquake.
c, the coil and the core by vacuum drying, 100kva oil transformer vacuum oil filter and oil filling process, the moisture inside the transformer to a minimum.
d, the tank using a corrugated sheet having respiratory function to compensate for temperature changes caused by changes in oil volume, so that the product does not conservator, apparently reducing the height of the transformer.
e, due to replace the conservator the corrugated sheets, transformer oil and the outside world, thus effectively preventing oxygen, moisture into the insulation and cause performance degradation.
f, according to the performance of the above five points, to ensure that the oil-immersed transformer oil change is not required in the normal operation, greatly reducing the maintenance cost of the transformer, while extending the life of the transformer.
