The Characteristics And Advantages And Disadvantages Of Oil-Immersed Transformer Are Introduced

Oil immersed transformer performance characteristics

a, oil immersed transformer low-voltage winding in addition to the small capacity of copper wire, generally use copper foil winding cylinder structure; The high voltage winding adopts the multi-layer cylinder structure, so that the ampere-turns distribution of the winding is balanced, the magnetic leakage is small, the mechanical strength is high, and the short-circuit resistance is strong.

b, the iron core and the winding are respectively using fastening measures, the device height, low pressure lead and other fastening parts are equipped with self-locking locknut, the use of non-hanging core structure, can withstand the transport of the shock.

c, coil and core using vacuum drying, transformer oil using vacuum filter oil and oil injection process, so that the moisture inside the transformer is reduced to a low.

D. The oil tank adopts corrugated sheet, which has respiratory function to compensate for the volume change of oil caused by temperature change, so the product has no oil storage tank, which obviously reduces the height of the transformer.

e, because the corrugated sheet replaces the oil storage tank, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and water and leads to the decline of insulation performance.

f, according to the above five points of performance, it ensures that the oil-immersed transformer does not need to change oil in normal operation, greatly reducing the maintenance cost of the transformer, and extending the service life of the transformer.

Oil immersed transformer advantages

1, transformer oil insulation performance is good, good thermal conductivity, while transformer oil is cheap.

2, can solve the transformer large capacity heat dissipation problem and high voltage insulation problem.

Oil immersed transformer disadvantages

1. Transformer oil is flammable and may burn and explode when it encounters flames

2, transformer oil is harmful to human body

3, transformer oil needs to be checked regularly

4, oil-immersed transformer seal performance is poor and should be aging, serious leakage of oil in the operation site, affecting the safe operation of equipment, while affecting the environment

5, oil-immersed transformer insulation grade is low, according to A class insulation design, manufacturing
