Abstract

Изобретение относитс  к электротехнике и может быть использовано в радиотехнике. Целью изобретени   вл етс  уменьшение дискретности регулировани  коэффициента трансформации. Автотрансформатор содержит тороидальный ферритовый магнитопровод 1, выполненный из набора колец 2, разделенных зазорами, через которые проход т ответвлени  3, соединенные электрически с витками 4 с внутренней стороны сердечника, благодар  чему напр жение снимаетс  с части витка 4 через ответвлени  3, каждое из которых охватывает часть магнитного потока, определ емую количеством охватываемых колец. В результате этого уменьшаетс  дискретность регулировани . 1 ил.The invention relates to electrical engineering and can be used in radio engineering. The aim of the invention is to reduce the resolution resolution of the transformation ratio. The autotransformer contains a toroidal ferrite magnetic core 1 made of a set of rings 2 separated by gaps through which the branches 3 are electrically connected to the coils 4 on the inner side of the core, whereby the voltage is removed from part of the coil 4 through the branches 3, each of which covers part of the magnetic flux determined by the number of rings covered. As a result, the control resolution is reduced. 1 il.

Claims (1)

Формула изобретенияClaim Регулируемый автотрансформатор, содержащий магнитопровод в виде набора колец и обмотку с ответвлениями, от личающийся тем, что, с целью уменьшения дискретности регулирования коэффициента трансформации, магнитопровод расщеплен, причем его кольца изолированы друг от друга зазорами, через которые проходят ответвления обмотки.An adjustable autotransformer containing a magnetic core in the form of a set of rings and a winding with branches, distinguished by the fact that in order to reduce the discreteness of the transformation ratio control, the magnetic core is split, and its rings are insulated from each other by gaps through which the windings pass.
