Description
Technical field
The present invention relates to transformer technology fields, more particularly, to a kind of transformer oil passage and transformer.
Background technology
For transformer, Wen Sheng is a crucial performance parameter, directly affects the service life of transformer, pungent by covering
6 degree of rules of heat ageing that lattice rule is released, within the temperature range of 80 to 140 degrees Celsius, the ageing rate of paper oil insulation is with temperature
The coefficient of variation is taken as constant, that is, temperature often increases 6K, and ageing rate increases by 1 times, the less half of transformer life.Existing skill
General use of the transformer oil passage of art pastes 6mm wide × 4mm thickness on 0.25mm or the cable paper of 0.13mm thickness with constant spacing
Cardboard rectangular stay, if increasing multilayer oil duct to increase transformer coil heat dissipation area, can use more conducting wire and
So that coil is become larger, Transformer Short Circuit Impedance value and load loss value can be influenced；If stay thickness is too thin, the slight pleat of cable paper
Wrinkle will block oil duct and then influence transformer coil heat dissipation, therefore stay thickness cannot be too thin；If stay thickness is too thick
Can influence Transformer Short Circuit Impedance and load loss, if in order to prevent cable paper fold and reduce stay spacing, stay can be made
More heat dissipation area is occupied, if increasing stay spacing, in transformer short-circuit, coil cannot be supported effectively and is easily deformed,
And then influence transformer anti-short circuit capability.
In addition the stay rigidity of traditional oil duct is too big, if unbalance stress easily misplaces in sudden short circuit, causes winding deformation
And the variation of reactance amount, and then influence transformer anti-short circuit capability.
The information for being disclosed in the background technology part is merely intended to deepen understanding of the general background technology to the present invention, and
It is not construed as recognizing or implying in any form that the information constitutes the prior art known to those skilled in the art.
