Oil-immersed transformers are commonly used power distribution equipment. What are the performance characteristics of the oil-immersed transformers? Do you know?
1.oil-immersed transformer low-voltage winding should use copper wire in addition to small capacity, generally use copper foil around the cylindrical structure; High-voltage winding use multi-layer cylindrical structure, so that the winding should be balanced, small magnetic flux leakage, high mechanical strength and strong anti-short circuit capability.
2.The core and the winding use a tightening measures, fastening parts have self-locking lock nut, with a non-hanging structure, can withstand the transport of the shock.
3.the coil and the core pass vacuum drying, transformer oil use vacuum oil and oiling process, so that the moisture inside the transformer to a minimum.
4.the fuel tank use corrugated sheet, it has a breathing function to compensate for changes in temperature caused by changes in oil volume, so the product is no oil conservator, obviously reduced the height of the transformer.
5.because the corrugated chip replace the oil conservator, so that the transformer oil isolated from the outside world, so as to effectively prevent the oxygen, water into the lead to the decline of insulation performance.
The above five performance ensure that the normal operation of oil-immersed transformer, greatly reducing the maintenance costs of the transformer, while extending the life of the transformer.
