Description

Изобретение относитс  к области электромашиностроени  и может быть применено при изготовлении крупных машин посто нного тока с т желыми услови ми коммутации. Известно, что в современных хорошо использованных машинах с высоким значением коэффициента полюсной дуги имеет место наложение пол  главных полюсов на поле добавочных полюсов в области коммутационной зоны, что ос.тажн ет услови  коммутации и делает машину более склонной к искрению.The invention relates to the field of electrical engineering and can be applied in the manufacture of large DC machines with severe switching conditions. It is known that in modern well-used machines with a high value of the pole arc ratio, the field of the main poles overlaps the field of the additional poles in the area of the switching zone, which sets the switching conditions and makes the machine more prone to sparking.

Задачей изобретени   вл етс  экранирование коммутационной зоны от главного пол  и улучшение тем самым условий коммутации.The object of the invention is to shield the switching zone from the main field and thereby improve the switching conditions.

Поставленна  задача решаетс  путем применени  системы тонких стальных пластин, расположенных между главными и добавочными полюсами и образующих вокруг последних магнитный экран, устран юШ .ИЙ наложение пол  главных полюсов на поле добавочных полюсовНа чертеже схематически показана конструкци  этого экрана и его расположение в магнитной системе машины.The problem is solved by applying a system of thin steel plates located between the main and additional poles and forming a magnetic screen around the latter, eliminating the overlap of the main poles on the additional pole field.

Две тонкие стальные пластины / помещаютс  между главными и добавочными полюсами таким образом, чтобы коммутационна  зона располагалась между пластинами. Нижние кра  пластин должны располагатьс  ниже краев башмаков главных полюсов, т. е. ближе к поверхности  кор . Ширина пластин должна быть достаточно велика дл  того, чтобы перекрыть поле рассе ни  с боковых поверхностей башмаков главных полюсов. Обе указанные пластины / соедин ютс  между собой с обеих или с одной стороны магнитной системы стальными планками 2, но так, чтобы в электрическом отношении экран не образовывал короткозамкнутого витка вокруг добавочного полюса.Two thin steel plates / are placed between the main and additional poles in such a way that the switching zone is located between the plates. The lower edges of the plates should be located below the edges of the shoes of the main poles, i.e., closer to the surface of the core. The width of the plates must be sufficiently large in order to cover the scattering field from the side surfaces of the shoes of the main poles. Both of these plates / are interconnected on both or one side of the magnetic system by steel strips 2, but in such a way that the screen does not form an electrically short-circuited coil around the additional pole.

Дл  того; чтобы дополнительное рассе ние главных и добавочных полюсов не слишком возросло, reждy полюсными башмаками главныхFor that; so that the additional scattering of the main and additional poles does not increase too much, with each pole shoes of the main

и добавочных полюсов и пластинами / должен оставатьс  достаточный зазор.and additional poles and plates / there should be sufficient clearance.

Пластины экрана креп тс  к башмакам главных полюсов с помощью деталей, изготовленных из немагнитного материала. Конфигураци  пластин 2 должна быть такова, чтобы они не затрудн ли измерение зазора под добавочными полюсами. Дл  этой цели в пластинах 2 сделаны прорези.The screen plates are attached to the main pole shoes with parts made of a non-magnetic material. The configuration of the plates 2 must be such that they do not make it difficult to measure the gap under the additional poles. For this purpose, slits are made in the plates 2.
