Description

Предлагаетс  устройство дл  обнаружени  короткозамкнутых витков в катушках, выполненное по типу трансформатора с разъемным двухоконным магнитопроводом и двум  катушками; на сердечник магнитопрОЕОда надеваетс  испытуема  катуи ка.A device for detecting short-circuited turns in coils is proposed, made as a transformer with a detachable two-window magnetic circuit and two coils; on the core of the magnetic media is put on the test katui k.

Отличительной особенностью предложенного устройства  вл етс  выполнение трансформатора из двух не св занных друг с другом магнитопроводо-в , причем испытуема  катушка надеваетс  на свободные от обмоток стержни, образуюш,ие двойной сердечник.A distinctive feature of the proposed device is that the transformer is made of two non-connected magnetic conductors, and the test coil is put on the winding-free rods that form a double core.

Принцип действи  устройства иллюстрируетс  чертежом.The principle of the device is illustrated in the drawing.

Первична  обмотка 1 подключаетс  к сети переменного тока. Испытуема  катушка 3 надеваетс  на стержень, обш,ий дл  обоих магнитопроводов , изолированных друг от друга диамагнитной прокладкой 4.Primary winding 1 is connected to AC power. The test coil 3 is put on the rod, sheathed for both magnetic cores, isolated from each other by a diamagnetic gasket 4.

При замыкании откидного  кор  5 и при наличии в испытуемой катушке короткозамкнутых витков в последних будет индуктироватьс  ток, который создаст переменный магнитный поток в магнитопроводе измерительной катушки 2. В последней изведетс  э.д.с., наличие которой бздет показывать отклонение стрелки прибора 6.When the flared core 5 closes and if there are short-circuited turns in the coil under test, a current will be induced in the latter, which will create an alternating magnetic flux in the magnetic core of the measuring coil 2. In the latter, emf will appear, which will indicate the deviation of the instrument 6.

При отсутствии короткозамкнутых витков в результате слабой магнитной св зи между катушками 1 2 отклонение стрелки будет ничтожно.In the absence of short-circuited coils as a result of weak magnetic coupling between the coils 1 2, the arrow deflection will be negligible.

Предмет изобретени Subject invention

Устройство дл  обнаружени  короткозамкнутых витков в электрических катушках, выполненное по типу трансформатора с разъемным двухоконным магнитопроводом, имеющим сердечник дл  надевани  на него испытуемой катушки и снабженным двум  обмотками - первичной , питаемой переменным током и служащей дл  намагничивани  сердечника, и вторичной измерительной , отличающеес  тем, что магнитопровод выполнен из двух независимых в магнитном отношении однооконных магиитоирОБОДов, один из которых несет намагничивающую обмотку, другой - измерительную , и оба имеют свободные 01 обмоток стержни, образующие двойной сердечник дл  надевани  испытуемой катушки.A device for detecting short-circuited coils in electric coils, made as a transformer with a detachable two-window magnetic circuit, having a core for putting the test coil on it and equipped with two windings - a primary coil, fed by alternating current and used for magnetizing the core, and a secondary measuring coil, different the magnetic circuit is made of two independently magnetic single-window magnetoIROBODs, one of which carries a magnetizing winding, the other is a meter both have free 01 winding rods that form a double core for donning the test coil.
