Study on Uniform Wind Field Formation Method in Icing Experiments
Wind has an important influence on surface icing of power transmission equipment under the freezing rain and snow weather
and which is one of the important parameters for researching icing mechanism of equipment and ice-melting of conductors
but it is very difficult to obtain uniform and stable wind in the artificial environment. This paper introduces the basic situation of artificial icing climate chamber with uniform wind. Based on the theory of free jet
it is proved through simulation calculation
wind tunnel scaling test and actual test in the artificial icing climate chamber that: Blowing mode is better than blowing-absorbing mode and absorbing mode in fan power and uniformity of wind. Also
uniform and stability wind can be achieved in the artificial icing climate chamber through the optimization design of tunnel structure. Uniform wind has little effect on the temperature distribution in the artificial climate chamber. This research can provide technical support for the effects of wind on the surface of transmission equipment icing and ice accretion rules.
