От контактной сети переменного тока электровоз получает однофазный ток промышленной частоты 50 Гц, номинального напряжения 25 000 В. Электрическое оборудование такого электровоза отличается от обору­дования электровоза постоянного тока главным образом наличием по­нижающего трансформатора и выпрямительной установки.
Трансформаторы выполняют с интенсивным циркуляционным мас-ловоздушным охлаждением. Принцип работы такого охлаждения ясен из рис 101.
В качестве выпрямителей обычно применяют кремниевые полу­проводниковые вентили — диоды (рис 102, а). В последнее время начали использовать также силовые кремниевые вентили — тиристоры (рис 102, б), которые позволяют управлять процессом токопрохождения.
Выпрямленное напряжение на зажимах тяговых электродвигателей не является постоянным во времени, а пульсирует; пульсация напряжения вызывает пульсацию вы­прямленного тока. Значительная пульсация неблагоприятно влияет на работу тяговых электродвига­телей, поэтому в их цепь вклю­чают дополнительные индуктив­ности — так называемые сглажи­вающие реакторы.
На рис. 103 показан элект­родвигатель НБ-418К электровозов ВЛ80К и ВЛ80Т с двусторонней пе­редачей и независимой вентиля­цией. Электродвигатель шестипо-люсный (6 главных и 6 добавоч­ных полюсов) с часовой мощно­стью 790 кВт и напряжением 950 В; подвешивание электродвигателя — опорно-осевое.

а — диод; б — управляемый веитнль (тири­стор); 1 — наконечник; 2 - гибкий внешний вывод; 3 — соединительная втулка; 4 — изо­лятор; 5 — крышка корпуса; 6 — внутренний гибкий вывод; 7 — пластина монокристалла кремния; 8— корпус медный: 9 — соедини­тельный стержень корпуса; 10 — вывод уп­равляющего электрода

Скорость электровоза перемен­ного тока регулируется измене­нием напряжения, подводимого к тяговым электродвигателям, путем подключения их к различным выво­дам вторичной обмотки трансфор­матора или выводам автотрансфор­маторной обмотки. При таком спо­собе регулирования отпадает на­добность в пусковых реостатах и в переключениях двигателей. На электровозах переменного тока тяговые электродвигатели все время соединены между собой параллельно. Это улучшает тяговые свойства электровоза и упрощает электрическую схему.
На электровозах переменного тока, помимо вспомогательного обо­рудования, применяемого на электровозах постоянного тока, есть еще и мотор-насосы, обеспечивающие циркуляцию масла, охлаждаю­щего трансформатор и мотор-вентилятор охлаждения трансформатора и выпрямителя.
Электродвигатели всех вспомогательных машин чаще всего трех­фазные асинхронные. Трехфазный ток преобразовывается из однофаз­ного с помощью специальных вращающихся или статических преобра­зователей, называемых расщепителями фаз.
Применение переменного тока при электрификации железных дорог вызвало необходимость организации пунктов стыкования двух родов тока —однофазного напряжением 25 000 В и постоянного напряжением 3000 В. При этом станции стыкования оборудуются специальными уст­ройствами для переключения напряжения в отдельных секциях кон­тактной сети. Хотя при таком стыковании локомотивы сменяются бы­стро, однако усложняется и удорожается устройство контактной сети. Кроме того затрудняется работа станции.

В ряде случаев целесообразно применение электровозов двойного питания, у которых возможны необходимые переключения электри­ческого оборудования для работы на участках постоянного и переменного тока. К электровозам двойного питания относятся электровозы, ВЛ82 и В Л 82м соответственно мощностью 5200 и 6000 кВт с конструк» ционной скоростью 110 км/ч.
