Özet:

 


An indirect method for determining the effectiveness of the
transformers operating in a distribution network with variable load schedules,
according to the parameter of their thermal load as a ratio of heat accumulated
by transformer oil to the maximum permissible heat is proposed provided the
thermal stability of the insulation. a mathematical model is
developed which allows establishing analytically the forced temperature value
and time invariable of heating or cooling on the section of the time dependence
of the oil temperature, as well as an algorithm for calculating the amount of
heat accumulated by the oil and the coefficient of heat transfer from the oil
to the transformer tank is compiled. approbation of the indirect
method indicates that the divergence between the
transformer oil heating time invariable which was obtained by solving the
differential equation of thermal balance and calculated using the part of
temperature dependence of its heating for two minutes, is 3.6%, and at
determination of the forced temperature value - 0.8%.
