| description | The article presents an algorithm for processing data by
the acoustic method of insulation power transformers.
The article presents data processing of diagnosing by the
acoustic method of power transformers. A feature of the
power supply system of railway transport is the location of
traction substations along the railway track. For diagnosing
power transformers advisable to use portable systems
based on acoustic monitoring of partial discharges due to
their high mobility and ease of installation. To improve the
reliability of diagnosis under the conditions of seasonal
temperature changes proposed use a defect simulator
and a differential method for measuring the parameters
of partial discharges. The scheme of the experiment and
the diagnostic algorithm are proposed. Expressions are
given that describe the properties of transformer oil with
temperature changes, and changes in signal parameters
during the propagation of acoustic waves. The data of
diagnostics obtained on a power transformer at positive and
negative temperatures under conditions of development of
an insulation defect accompanied by partial discharges are
presented. |
