Электрификация постоянным и переменным током


Recommended Posts

А зачем опускать пантографы?

Чтобы не было даже теоретической возможности замкнуть КС на землю через электровоз. И что никакой нагрузки при переключениях не будет подключено. Перестраховка.

А так -- силовую схему на электровозе УРТ (устройство контроля рода тока) и без опускания токоприёмника пересоберёт.
