Description
Изобретение относитс к электротехнике и предназначено дл синмет- ч, р ровани режима трехфазной сети пр| питании от нее стабилизированным током мощных однофазных нагрузок, например электротермических и электрб-. сварочных установок.ПО ocHOBHpisftr авт.- св. №378821 известно устройство дл питани однофазной нагрузки от трехфазной сети, например, электротермических .и электросварочные установок, содер вдащее конденсаторную батарею и дроссель, настроенные в резонанс на частоту питающей сети и соединенных с цепью дл подключени нагрузки в звезду, выводаг лучей которой подключены к трехфазному источнику напр жени , причем последовательно в нагрузочную цепь включен дополнительный регулирующий элемент, выполненный в виде автономного, ре 17улируемого по величине и фазе источййка ЭДС,The invention relates to electrical engineering and is intended to synmetrize the operation of a three-phase network mode. powered from it by a stabilized current of powerful single-phase loads, such as electrothermal and electrb-. welding installations.PRO ocHOBHpisftr avt.- st. No. 378821, a device is known for supplying a single-phase load from a three-phase network, for example, electrothermal and electric welding installations, containing a capacitor battery and a choke, tuned to the frequency of the supply network and connected to a circuit to connect the load to a star, the output beams of which are connected to a three-phase a voltage source, with an additional regulating element, made in the form of an autonomous, re-regulated in magnitude and phase source of emf, sequentially included in the load circuit,
Указанные трехфазиый источник нешр женй и регулируекел источник ЭДС выполнены в виде двух однофазных трансформаторов, первичные обмотки которых, подключаемые к трехфазной сети, соединены по схеме трансформатора Скотта, вторична обмоткаThese three-phase sources of external and regulator sources of EMF are made in the form of two single-phase transformers, the primary windings of which, connected to the three-phase network, are connected according to the Scott transformer circuit, the secondary winding
трансформатора снабжена прсадежуточными выводами дл подключени к сво6однс 4у концу нагрузки, крайний вывод этой обмотки св зан с промежуточным выводом вторичной облютки второго трансформатора, а к ее крайним выводам прдсоеданены конденсаторнгш батаре и дроссель. Вторична обмотка второго трансформатора снаб10 жена несколькими промежуточными выводами и переключателем дл св зи ее со вторичной обмоткой первого трансформатора.The transformer is equipped with prospective leads for connecting the load to the 4th load end, the extreme lead of this winding is connected with the intermediate lead of the second transformer, and a capacitor battery and choke are connected to its extreme leads. The secondary winding of the second transformer is provided with several intermediate leads and a switch for connecting it to the secondary winding of the first transformer.
Недостатком выполнени трехфазно15 го источника напр жени и регулируемого источ.ника ЭДС в виде двух трансформаторов , соединенных по схеме трансформатрра Скотта, вл етс больша их установленна мощность , The disadvantage of the implementation of a three-phase voltage source and an adjustable source of EMF in the form of two transformers connected according to the Scott transformer scheme is their greater installed power,
20 ( в 2,5 раза превышаки11а1 номинальную мощность нагрузки).20 (2.5 times higher than 11a1 rated load power).
Цель изобретени - уменьшение The purpose of the invention is to reduce
