Modeling and calculation of temperature distribution along the length of a wire studying problems the capacity of power transmission lines near contact connections
The article has obtained an analytical solution to the thermal conductivity equation for the contact connection of long sections of overhead lines, and also considered the case for a line with two short and two long sections, which makes it possible to take into account distributed defects and cl...

| description | The article has obtained an analytical solution to the thermal conductivity equation
for the contact connection of long sections of overhead lines, and also considered
the case for a line with two short and two long sections, which makes it possible
to take into account distributed defects and clamp sizes. The application of the
obtained mathematical model to determine the temperature of an overhead power
line near contact connections is shown. A comparative analysis of the temperature
values in the power line, calculated using the created mathematical model, with
published data obtained based on finite element modeling using the results of
a physical experiment is performed. It has been shown that heating of contact
connections can significantly limit the throughput of lines even at an acceptable level
of contact resistance. This makes relevant the tasks of calculating the temperature
of contact connections of power lines and clarifying permissible currents taking into
account the influence of transient contact resistances. |
