Optimization of drive parameters for electric mine locomotives

Article preview

The state of mine electric locomotive transport and the main directions of mine electric locomotive drive improvement are shown. The expediency of introducing a new train weight limitation into the traction calculation methodology under the condition of electric locomotive drive acceleration is indicated. The criterion for electric locomotive drive control when moving the assembled train from the place is given, the implementation of which allows to increase the service life of trolleys coupling devices. The possibility of increasing traction properties of mine electric locomotives by means of combined drive is considered. The efficiency of using of traction motors with mixed excitation on mine electric locomotives is shown.

Automation of mine electric locomotive transport

Article preview

Three directions of automation of mine electric locomotive transportation are considered: automation of starting and braking modes, automatic system of train collision avoidance and dispatch control system. The scheme of calculation of parameters of the automation system of mine electric locomotive transportation is given. It is shown that during the calculation it is necessary to take into account the limitations imposed by the peculiarities of the transportation network, parameters of mining sites, ore preparation devices.

Peculiarities of traction calculation of mine automated electric locomotive transport

Article preview

Improvement of mine electric locomotive drive aimed at creation and implementation of automatic starting systems determines the definition of adjustable drive parameters at the design stage. At given parameters of the automated drive, carriages, grip coefficient of electric locomotive wheels with rails, it is reasonable to calculate the train mass under the condition of its acceleration. The mass can be limiting in comparison with the mass determined by other known conditions of traction calculation.

Criteria of mine electric locomotive control during train moving from a place

Article preview

One of the stages of train starting is its moving from the place, defined from the moment of the electric locomotive starting to the moment of the last carriage starting to move. This stage is characterized by insignificant transient time (1-5 s) and large dynamic loads arising in the coupling devices of the cars. These loads are 3-10 or more times higher than the hourly value of the electric locomotive tractive force ...

Экспериментальное исследование системы автоматического поддержания заданной скорости преобразовательного электровоза

Article preview

При движении электровоза по прямолинейному участку пути сопроти­вление движению беспрерывно меняется вследствие изменения профиля пути нуклона. В работе А. А. Ренгевича указывается, что очень важно правильно учесть уклон пути, поскольку в шахтных условиях постоянные уклоны встре­чаются редко. Более того, при движении поезда в одном направлении име­ются уклоны, меняющиеся не только по величине, но и по знаку. Тяговые двигатели электровоза обладают мягкой механической характеристикой, поэтому при малых нагрузках скорость электровоза изменяется в значитель­ных пределах. Для поддержания заданной скорости электровоза при дви­жении по прямолинейному участку пути машинист должен беспрерывно манипулировать ручкой контролера. Исследования, произведенные В. П. Гудаловымна шахтах Донбасса, показали, что в среднем на один час работы тяговых двигателей электровоза приходится более 700 переключений пози­ций контроллера, что неблагоприятно сказывается на режиме работы двига­телей. Создание электровоза с автоматическим поддержанием заданной ско­рости значительно облегчит труд машиниста, а также уменьшит условия возможного буксования колес при разгоне и движении электровоза по пря­молинейному участку пути при изменяющемся моменте сопротивления на валу двигателя ...
