Description

Изобретение относитс к электрома шиностроению, в частности к крупным синхронным компенсаторам с водородным охлаждением.The invention relates to electro-bus industry, in particular to large synchronous compensators with hydrogen cooling.

Известны синхронные компенсаторы, у которых из корпуса машины вывод тс шесть концов от обмотки статора. Трансформаторы тока устанавливаютс снаружи компенсатора в отдельном помещении . Первичными обмотками трансформаторов тока вл ютс нулевые концы обмотки статора С 1 3.Synchronous compensators are known, in which six ends are drawn from the machine body from the stator winding. Current transformers are installed outside the compensator in a separate room. The primary windings of current transformers are the zero ends of the C 1 3 stator winding.

Недостатком такого устройства вл етс необходимость вывода из корпуса компенсатора шести выводных концов , вместо трех, что снижает надежность синхронных компенсаторов с водородным охлаждение;м в св зи с увеличением возможных мест утечки водорода .A disadvantage of such a device is the need to remove six output ends from the compensator body, instead of three, which reduces the reliability of synchronous compensators with hydrogen cooling, due to an increase in the possible places of hydrogen leakage.

Наиболее близким к изобретению вл етс синхронный компенсатор с принудительным водЬродным охлаждением, содержащий герметизированный корпус, в котором размещен статор с обмоткой, соединенной в звезду, с начальными и нулевыми отводами, газоохладители с входной и выходной зонами по воддро-ду , размещенные в кожухе, присоеди-.. ненном к корпусу, и установленные наClosest to the invention is a synchronous compensator with forced hydrogen cooling, containing a sealed housing in which a stator with a winding connected in a star with initial and zero taps is placed, gas coolers with input and output zones along the water line, placed in the casing, connect - .. to the body, and installed on

нулевых отводах обмотки статора трансформаторы тока С2 .zero taps of the stator winding current transformers C2.

Недостатком такой.конструкции вл етс то, что трансформаторы тока, располага сь напротив лобовой части обмотки по оси машины на некотором рассто нии, определ е2иом диэлектрическим промежутком от лобовой части до щита, уйеличивают осевой размер компенсатора и его массу. Кроме того, такое расположение не позвол ет эффективно охйаждать трансформаторы тока и нулевые отводы потоками охлаждающего газа (в данном случае, водо5 родом) , что снижает надежность синхронного компенсатора.The disadvantage of this design is that current transformers, located opposite the winding frontal part along the machine axis at a certain distance, determined by the dielectric gap from the frontal part to the shield, increase the axial size of the compensator and its mass. In addition, this arrangement does not effectively cool current transformers and zero taps with cooling gas (in this case, water), which reduces the reliability of the synchronous compensator.

Claims

The synchronous compensator consists of a sealed enclosure 1, the stator core 2 with winding 3 is placed in the 30 rum cylinder. The winding has three initial leads 4, brought out through current isolators in the upper part of the compensator housing, and three zero leads 5 of the stator winding, brought into the casing b, located at the bottom of the compensator. In the housing there are gas coolers 7 and there are inlet zone B, into which hydrogen heated in the compensator is supplied, and outlet zone 9, into which gas cooled in gas coolers is supplied. In the casing, in the hydrogen outlet zone, current transformers 10 are located, the primary windings of which are formed by zero outlets 5 of the stator winding. After the current transformers, the ends of the phases are closed with each other by a jumper, forming a stator winding connection into a star. . For mounting the current transformer in the housing, a hatch 11 is provided. The location of the current transformers in the gas cooler housing reduces the spacing of the stator winding to the compensator face shield and, accordingly, reduces the axial length of the compensator, which is especially important in large synchronous compensators with hydrogen. cooling, the axial length of which is limited by the dimensions of the railway plate of the form for transporting the stator of the synchronous compensator. Due to the fact that the gas cooler covers are schematic, a slight increase in their dimensions does not affect the size of the compensator, limited by rail traffic. At the same time, the location of the current transformers in the zone, the output of hydrogen into which the cooled gas flows, allows for the effective cooling of the transformers and zero leads, since the transformer casing and tires are completely washed by cold gas flows, which increases the thermal loads of the current transformers and reduces their dimensions. Thus, the implementation of the hydrogen cooled synchronous compensator of the present invention allows reducing the axial envelope of the machine and increasing its reliability by improving the cooling of current transformers: Claims The synchronous compensator with forced hydrogen cooling containing a sealed enclosure containing a stator with a winding connected in star, with initial and zero taps, gas coolers with hydrogen inlet and outlet zones, housed in a housing attached to The transformers installed on the Zero outlets of the stator winding are also distinguished by the fact that, in order to reduce overall dimensions and increase reliability, current transformers with zero stator windings are installed in the gas cooler housing in the outlet zone of the hydrogen. tie into account during the examination 1.
