Description

Примен емый в практике электромашиностроительных заводов способ испытани  железа статора витками заключаетс  в проведении теплового режима перемагничивани  си инки статора. По этому методу дл  испытани  вокруг спинки наматываютс  две обмотки - намагничиваюпда  и измерительна , а в железо закладываетс  р д термопар. Качество сборки испытуемого железа оиениваетс  по потер м в железе, отнесенным к весу спинки, а о наличии замыканий в железе суд т по наибольшим местным перегревам, отыскиваемым на ощупь.The method of testing the stator iron with coils used in the practice of electrical engineering plants is to carry out the thermal mode of magnetization reversal of the stator bore. According to this method, two windings are wound around the backrest - magnetized and measuring, and a series of thermocouples is laid in the iron. The build quality of the test iron is measured by the loss in iron related to the weight of the back, and the presence of closures in the iron is judged by the greatest local overheating that is felt to the touch.

Однако при таком методе испытани  невозможно обнаружить наличие замыканий в зубцовой зоне статора, а также необходимы значительные затраты труда и времени при наложении на .статор обмоток, проведении длительного теплового режима и т. п.However, with this method of testing, it is impossible to detect the presence of closures in the tooth-like zone of the stator, and significant labor and time costs are required when applying a winding for a long-standing thermal condition, etc.

Предлагаемый способ испытани  железа статора электрических машин основан на измерении потерь на отдельных участках железа статора.The proposed method for testing the iron of a stator of an electric machine is based on the measurement of losses in individual sections of the iron of the stator.

Согласно изобретению дл  создани  магнитного потока в испытуемом участке железа статора примен ют электромагнит с П-образным сердечником, на котором намотаны намагничивающа  и измерительна  обмотки. При испытании П-образный сердечник прикладывают полюсами к исследуемому участку статора. Такой способ упрощает и ускор ет весь процесс испытани .According to the invention, in order to create a magnetic flux in the test section of the iron of the stator, an electromagnet with a U-shaped core is used, on which the magnetizing and measuring windings are wound. When testing the U-shaped core is applied by the poles to the test section of the stator. This method simplifies and speeds up the entire testing process.

Па чертеже изображена схема, по сн юща  предложенный способ испытани  железа статора электрических машин.Pa of the drawing is a diagram illustrating the proposed method for testing the iron of the stator of electric machines.

П-образный сердечник электромагнита устанавливают в различных местах расточки статора. По ваттметру W и амперметру А измер ют потери в железе, причем величина магнитного потока устанавливаетс U-shaped core of the electromagnet is installed in various places of the bore of the stator. A wattmeter W and an ammeter A measure iron losses, the magnitude of the magnetic flux is set to

Во избежание замыканий в местах стыков сердечника с железом статора прокладывают прессшпановые прокладки толщиной 0,15- 0,2 мм.In order to avoid short circuits at the joints of the core with the stator iron, press-on gaskets with a thickness of 0.15-0.2 mm are laid.

Размеры сердечника задаютс  применительно к определенному габариту машины, и в услови х серийного производства такой сердечник используетс  дл  всех машин данного габарита.The dimensions of the core are set in relation to a certain machine dimension, and under mass production conditions such a core is used for all machines of a given dimension.
