General transformer fault type mainly has thermal fault and electric fault, and wherein thermal fault accounts for the 60% of total failare number of units
Left and right, overheats and high-energy discharge failure accounts for 10% or so.The oil-immersed transformer service life depends primarily on the service life of insulating materials, and
The deciding factor for promoting insulating materials aging is exactly temperature, therefore hot-spot temperature of transformer determines the use longevity of transformer
Life.
Past requires to be unable to monitor with internal strong electromagnetic, the temperature of hot spots due to transformer interior insulation.Out
In security consideration, Domestic Transformers greatly all under 50% ~ 70% rated power, non-economy operation conditions.Pass by all to be logical thus
Cross and current transformer be installed in casing part, return the hot spot temperature of winding of the method measuring transformer of analog signal, error compared with
Greatly.Therefore, for how to search out the technology hand of hot(test)-spot temperature that effectively can accurately detect inside transformer winding temperature a kind of
Section is just particularly important.
