Description

ПОДВЕСНОЙ ТРАНСФОРМАТОР ТОКА ДЛЯ ВЫСОКОВОЛЬТНЫХSUSPENDED CURRENT TRANSFORMER FOR HIGH-VOLTAGE

За влено 23 марта 1959 г. за № 623723/24 в Комитет по делам изобретений и открытий при Совете Министров СССРIt was filed on March 23, 1959 with No. 623723/24 to the Committee for Inventions and Discoveries under the Council of Ministers of the USSR

Опубликовано в «Бюллетене изобретений № 14 за 1961 г.Published in the Bulletin of Inventions No. 14 for 1961.

Известные типы трансформаторов тока из-за большого объема и веса изол ции имеют большие габариты и высокую стоимость.The known types of current transformers, due to the large volume and weight of the insulation, have large dimensions and high cost.

Предлагаемый трансформатор отличаетс  упрощенным устройстводМ . Это достигаетс  тем,что его изол ционна  оболочка имеет форму кольца с радиальным и суживающимс  к концу отростком, внутри которого расположены выводы вторичной обмотки. Материал кольца выбран по услови м электрической прочности над пробой, а материал отростка - по услови м прочности на скольз щий разр д.The proposed transformer is characterized by a simplified device M. This is achieved by the fact that its insulating sheath is in the form of a ring with a radial and tapering process, inside of which are located the conclusions of the secondary winding. The material of the ring was chosen according to the electric strength conditions above the breakdown, and the material of the process, according to the conditions of resistance to sliding discharge.

По заключению Свердловского совнархоза предлагаема  конструкци  трансформатора обладает р дом преимуществ по сравнению с существующими трансформаторами тока дл  измерени  в высоковольтных сет х.According to the Sverdlovsk Economic Council, the proposed transformer design has several advantages over existing current transformers for measuring in high-voltage networks.

Па фиг. 1 дано схематическое изображение конструкции трансформатора; на фиг. 2 - вариант трансформатора дл  внутренней установки .Pa figs. 1 shows a schematic representation of the transformer design; in fig. 2 - Transformer variant for indoor installation.

Трансформатор (фиг. 1) содержит замкнутый кольцевой сердечник /, вторичную обмотку 2, запрессованную в оболочку 5 из электроизол ционного материала. Поверх вторичной обмотки расположена первична  обмотка высокого напр жени  (на чертеже не показана), не имеюща  изол ции, что оказалось возможным благодар  надежной изол ции вторичной обмотки. В радиальном отростке 4 кольца расположены выводы вторичной обмотки.The transformer (Fig. 1) contains a closed ring core /, the secondary winding 2, pressed into the shell 5 of an electrically insulating material. A high-voltage primary winding (not shown in the drawing) is located on top of the secondary winding. It is not insulated, which was possible due to reliable insulation of the secondary winding. In the radial process of the 4th ring, the terminals of the secondary winding are located.

Основанием дл  креплени  трансформатора служит стеклотекстолитова  пластинка 5 (фиг. 2), котора  приклеиваетс  к корпусу. Пластинка имеет отверсти  6 дл  креплени  проводов электросети к первичной обмотке.The base for fastening the transformer is a glass-cloth laminate plate 5 (Fig. 2), which is glued to the housing. The plate has holes 6 for fastening the power supply wires to the primary winding.
