Description
Изобретение относитс к области электроконтактного нагрева заготовок перед ковкой и штамповкой.This invention relates to the field of electrical contact heating of blanks before forging and stamping.
Известны электроконтактные многопозиционные нагревательные установки, содержащие трехфазный трансформатор и три пары контактных колодок. Одна колодка каждой пары соединена со вторичной обмоткой трансформатора , а другие - объединены шиной, соединенной со вторичными обмотками.Known electrocontact multi-position heating installation containing a three-phase transformer and three pairs of contact pads. One block of each pair is connected to the secondary winding of the transformer, while the others are connected by a bus connected to the secondary windings.
С целью экономии электроэнергии и электропровод ш ,их материалов предложенна установка снабжена дополнительной парой колодок, одна из которых соединена с упом нутой шиной, а друга - с нулевой точкой вторичных обмоток трансформатора.In order to save electricity and electrical wirings, their materials, the proposed installation is equipped with an additional pair of pads, one of which is connected to the said bus and the other to the zero point of the secondary windings of the transformer.
На чертел е изображена схема подключени нагреваемых заготовок в силовую цепь на электроконтактной многопозиционной установке .The drawing shows a scheme for connecting the heated billets to a power circuit at an electrical contact multi-station installation.
К трехфазному трансформатору 1 подключены пары контактных колодок 2-5. Одна колодка каждой пары 3-5 подключена к одному из выводов вторичных обмоток трансформатора соответствуюшей фазы, остальиые To the three-phase transformer 1 pairs of contact pads 2-5 are connected. One block of each pair of 3-5 is connected to one of the conclusions of the secondary windings of the transformer of the corresponding phase, the rest
колодки 3-5 объединены шиной вместе с одной из колодок 2, друга колодка 2 соединена с нулевой точкой вторичных обмоток трансформатора.blocks 3-5 are connected by a bus together with one of the blocks 2, the other block 2 is connected to the zero point of the secondary windings of the transformer.
Первична обмотка может быть соединена по любой из известных схем независимо от соединени нагрузки (на схеме показано дл примера соединение первичных обмоток в звезду без нулевого провода).The primary winding can be connected by any of the known circuits, regardless of the load connection (the diagram shows for example the connection of the primary windings into a star without a neutral wire).
Предмет изобретени Subject invention
Электроконтактна многопозиционна нагревательна установка, содержаща трехфазный трансформатор и три иары контактных колодок, из которых одна колодка каждой иары соединена со вторичной обмоткой трансформатора, а другие - объединены шиной , отличающа с тем, что, с целью экономии электроэнергии и электропровод щих материалов, она снабжена дополнительной парой колодок, из которых одна соединена с упом нутой шиной, а друга - с нулевой точкой вторичных обмоток трансформатора,An electrical multi-position heating installation comprising a three-phase transformer and three contact pads, of which one plug of each cable is connected to the secondary winding of the transformer, and the others are connected by a bus, which is equipped with an additional a pair of blocks, one of which is connected to the mentioned bus and the other to the zero point of the secondary windings of the transformer,
