Finite-Element Model Based Distribution Calculations of Current and Temperature within a DC Overhead Catenary
There is proposed finite-element model of current/temperature distribution in a DC overhead catenary and are described basic principles of its generation. The author analyzes existing calculation procedures of the current distribution/catenary wire heating and highlightes their limitations. Based on...

| description | There is proposed finite-element model of current/temperature distribution in a DC overhead catenary and are described basic principles of its generation. The author analyzes existing calculation procedures of the current distribution/catenary wire heating and highlightes their limitations. Based on the calculation results there are discussed typical current modes and thermal conditions of the key design components of DC catenary design versions enjoying wide application on railway transport (such as contact wire, catenary messenger, line feeder, Z-type anchor, electrical connectors and droppers). Two cases are analyzed, inclusive of traction current transit along the constant tension section and current pick-off by current collector passing along this section. On the basis of analysis there are indicated structural weakness areas of the catenary and is proposed method for their neutralization. |
