  • Accidents of icing on catenary have great impacts on normal operation of electrical railway. In order to guarantee traction power supply, an online anti-icing technology for catenary was proposed based on the static var generator (SVG). Heat balance equations for catenary were built, and solved results were compared with test results and data provided by the TB/T 2809-2005 to prove the correctness of the technology. The temperature fields of catenary during running of the online anti-icing system were calculated, and the factors influencing temperature distribution, such as train velocity and load current, were analyzed. The analyzed result shows that when ambient temperature is -4 ℃ and target temperature is 2 ℃, maximum temperature difference of droppers and clamps will reach to 5.3 ℃, so droppers and clamps may be weakest.
