Частотные преобразователи Hitachi имеют большие возможности векторного контроля при настраивании и создании программного обеспечения. Они также обеспечивают простоту программирования, возможна установка модулей со многими опциями, дают возможность выше расширять места использования. Преобразователи частоты Hitachi имеют такие преимущества: эффективность расхода энергии, удобный и приятный встроенный интерфейс и вход датчика тепловой защиты, подключение к линии сервисов мира и частотной характеристике.

Японские инженеры учитывают особенности российского пользователя и все частотники Hitachi попадающие на российский рынок способны выдерживать, практически любые нагрузки. Быть может, именно учитывая российские нагрузки и манеру пользования, японцы и наделили свои преобразователи частоты возможностью выдерживать кратковременные перегрузки в 200%. Но это не означает, что приборы смогут штатно работать под такой перегрузкой. Рассчитывать нагрузку нужно грамотно, с запасом в 20%. Тогда любой частотный преобразователь Hitachi будет работать без поломок, свыше заявленных в паспорте сроков.

Преобразователи частоты Hitachi можно встретить практически на любом производстве и в любом цеху. Также они применяются при строительстве насосных станций, систем вентиляции больших зданий и жилых домов. Применяются как в промышленности всех направлений, так и в сельскохозяйственной деятельности.

Немного истории

Частотные преобразователи и промышленная автоматизация производиться в Японии с 1979 года. Именно тогда Хитачи начала выпускать первые преобразователи частоты и системные реле. Наработки тех лет легли в основу производства современных преобразователей частоты и блоков автоматического управления производством.

Сегодня, все приборы компании разрабатываются с учётом возможностей и потребностей электросетей региона, куда намерены направить на реализацию партию частотников. Также, все приборы Хитачи соответствуют стандартам как страны назначения, так и международным CE и UL.

Авторитет среди пользователей преобразователи частоты из Японии получают и потому что, компания Хитачи стремится использовать для сборки только собственные компоненты. Таким образом, инженеры Хитачи отвечают за каждый узел и каждую микросхему в собранном ими приборе, что существенно увеличивает надёжность готового продукта.

Таким образом, удаётся добиться высокого уровня отказоустойчивости и надёжности прибора, а также защитить двигатель. Частотный преобразователь Hitachi – верное решение профессионалов.

Частотные преобразователи Hitachi SJ200

Особо примечательной моделью в линии ПЧ Хитачи является Hitachi sj 200. Рассмотрим несколько особенностей этого частотника. Конструкция имеет компактный фильтр большой мощности. Он сохраняет объем, который предусмотрен для управляемости моторов. Частотник является сильным устройством, обладает оптимизацией ISPM. Лучшие параметры эксплуатации и схема дают большое усилие вращения в трудных эксплуатационных условиях.

Частотный преобразователь Hitachi SJ200 инвертор по своим размерам маленький корпус для своего класса, идеален для типографий, целлюлозной, легкой отрасли, для лифтовых и подъемных механизмов и металлообработки.

Также, компактный преобразователь частоты Hitachi SJ200 имеет в своем оборудовании тормозной блок, фильтр магнитных помех, потенциометр, двигатель с термистором, соответствует международным стандартам, панель управления обеспечивает простоту использования. Имеется векторная бессенсорная регулировка, сбережение электроэнергии в автоматическом режиме.

Частотники Хитачи очень надежные механизмы с функциональными приводами для заводских условий, где нуждаются в регулировке оборотов электромоторов. Нет такой отрасли производства, где бы нельзя было использовать преобразователи тока Хитачи.

Инверторы Hitachi sj 200 объединяют в себе две группы преобразователей частоты:

Оба этих класса преобразователей частоты могут применяться в сетях как США, так и Европы. Несмотря на то, что входящие параметры напряжения разнятся, частотник Hitachi sj 200 может работать как с одними параметрами, так и с другими.

Входящее питание для инвертора класса 200 В должно быть в пределах 200 – 240 вольт, а напряжение для класса 400 В, варьируется в пределах 380 – 480 вольт. Напряжение переменное. Отдельные модели Hitachi sj 200 допускают работу, как в однофазной сети, так и в трёхфазной. Но все представитель класса 400 В работают в трёхфазных сетях.

Если на предприятии не имеется трёхфазного питания, то своё внимание лучше обратить на преобразователь частоты Hitachi sj 200 с мощностью до 2,2 кВт. Он гарантировано сможет работать от однофазной сети, при этом выдавать на выходе полноценную мощность электрического двигателя.

Для Hitachi sj 200 очень важно, чтобы прибор был заземлён. Заземлению подлежит и корпус самого электрического двигателя, который работает от ПЧ. Это нужно как для безопасности пользователя, так и для защиты самого прибора. Электронные компоненты частотника могут выйти из строя из-за скопившегося на корпусе прибора статического напряжения.

При подключении ПЧ Hitachi sj 200 используются стандартные обозначения. Если имеем дело с однофазным преобразователем частоты, то обозначения соответственно фаза и ноль. Если имеем дело с трёхфазным, то фазы обозначаются по очереди: фаза 1, фаза 2, фаза 3 и ноль. Очерёдность фаз соответствует входящим клеммам электрического двигателя (Т1, Т2, Т3).

При подключении электрического двигателя и при пробном пуске нужно убедиться, что вал крутится в нужном направлении во избежание поломки агрегата и травм персонала.

Для изменения направления вращения вала нет необходимости физически переподключать фазы. Это можно сделать и через интерфейс управления, просто введя нужную настройку. Преобразователь Hitachi позволяет делать такую настойку.

О программируемых функциях Hitachi sj 200

Удобство управления электрическим двигателем обеспечивает система программирования преобразователя частоты.

Преобразователь частоты Hitachi sj 200 управляется центральным микропроцессором по программе, которая занесена в EEPROM (ППЗУ). В памяти прибора хранятся заданные пользователем параметры, и по ним осуществляется управление работой электрического двигателя.

Hitachi sj 200 оснащён и дополнительным устройством считывания и записи информации. Эта опция позволяет упростить работу сборщиков систем управления. Эта возможность позволяет точно скопировать настройки одного инвертора в другой.

О торможении двигателя

Разумеется, не только движение важно в современном производстве. Также нередко приходится использовать и функцию торможения двигателя, когда вал на больших оборотах продолжает вращаться по инерции. Система торможения с использованием стопорных устройств и тормозных колодок не применяется уже очень давно.

Hitachi sj 200 имеет в себе и алгоритм торможения двигателя.

Общее понятие торможения в данном случае включает в сети воздействие магнитной силы, в противоположном направлении движения вала. То есть преобразователь частоты меняет кратковременно параметры штатной работы и стремится погасить энергию движения вала двигателя.

Тут важно соблюдать меру, так как противодействие магнитной индукции вызывает сильный нагрев обмоток двигателя. Что может привести к перегоранию обмоток. Но за это тоже отвечает сам преобразователь частоты. Он может, как интеллектуально вычислять возможный перегрев и бороться с ним, а может и с помощью датчика тепловой защиты двигателя определять перегрев и не допустить поломки двигателя.
