A wind deflection angle calculation method of considering wire
stress change. The wind deflection angle calculation method
comprises the following steps:
- calculating wire stress under a ruling span when the
temperature changes in the presence of wind;
- calculating a horizontal component and a vertical component of
the stress at a wire suspension point during wind deflection; and
(3) applying the wire stress obtained in the step (2) into a rigid
straight bar method, and obtaining a new calculation formula of
calculating the wind deflection angle of a suspension insulator
string.
- According to the wind deflection angle calculation method, the
effects of the wind deflection angle caused by wire stress change
in different working conditions are considered; and the traditional
calculation formula of the wind deflection angle of the suspension
insulator string is optimized and supplemented. The wind deflection
angle calculation method is of great significance in guarantee of
safe operation of a power network.
