Проанализированы существующие методики расчета токораспределения и нагрева проводов контактной подвески, отмечены их недостатки. На основании данных расчета распределения тока и температуры для нескольких типовых конструкций контактных подвесок постоянного тока, широко применяемых на сети железных дорог, рассмотрены характерные токовые и тепловые режимы работы основных конструктивных элементов: контактного провода, несущего троса, усиливающего провода, тросов средней анкеровки, проводов электросоединителей, струн. Это сделано в двух различных случаях - транзит тягового тока вдоль анкерного участка и проход токоприемника по нему со съемом тягового тока. На базе анализа результатов показаны слабые места в контактной подвеске и предложен способ их нейтрализации.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контактная подвеска</kwd><kwd>анкерный участок</kwd><kwd>распределение тока</kwd><kwd>распределение температуры</kwd><kwd>метод конечных элементов</kwd><kwd>транзит тягового тока</kwd><kwd>проход токоприемника</kwd></kwd-group><kwd-group xml:lang="en"><kwd>overhead catenary</kwd><kwd>constant tension section</kwd><kwd>current distribution</kwd><kwd>temperature distribution</kwd><kwd>finite-element method</kwd><kwd>traction current transit</kwd><kwd>current collector passage</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Воронин А.
