Description
Известны устройства дл контрол исправности цепей трансформаторов напр жени , соединенных в открытый треугольник. Эти устройства содержат электромагнитное реле с двум обмотками, подключенными соответственно к заземленному и незаземленному проводам, ч общей точке обмоток соединенной с контролируемым проводом.Devices are known for monitoring the health of voltage transformers connected to an open triangle. These devices contain an electromagnetic relay with two windings connected respectively to grounded and non-grounded wires, the common point of the windings connected to the monitored wire.
Предлагаемое устройство отличаетс от известных упрощенной схемой. Это достигаетс тем. что корь реле снабжен зубцом, который удерживает сигнальный флажок при прит нутом коре и выбивает его при сн тии напр жени с одной или обеих обмоток. Кроме этого, дл замыкани цепей сигнализации при отпадании кор использованы блок-контакты реле.The proposed device differs from the known simplified scheme. This is achieved by those. that the measles relay is provided with a prong that holds the signal flag when the cortex is pulled in and knocks it out when the voltage is removed from one or both windings. In addition, for the closure of the alarm circuits when the core disappears, the relay contacts are used.
В заключении Союзглавэнерго при Госплане СССР отмечаетс новизна и промыщленна полезность предложени .In conclusion, the Soyuzglavenergo under the USSR State Planning Committee noted the novelty and industrial value of the proposal.
На фиг. 1 изображена принципиальна схема устройства; на фиг. 2 - показано фото кор реле с зубцом.FIG. 1 is a schematic diagram of the device; in fig. 2 shows a photo of a relay core with a prong.
Предлагаемое устройство представл ет собою электромагнитное реле / с двум обмотками 2 и 5, включенными через выпр мители 4 и 5 на два напр жени сторон разомкнутого треугольника: обмотка 2 включена между незаземленным проводом 6 н контролируемым проводом 7, а обмотка 3 - между заземленным проводом 8 и контролируемым - 7.The proposed device is an electromagnetic relay / with two windings 2 and 5 connected via rectifiers 4 and 5 to two voltages of the sides of an open triangle: winding 2 is connected between ungrounded wire 6 n by controlled wire 7, and winding 3 is between grounded wire 8 and controlled - 7.
Реле / в нормальном режиме находитс в рабочем состо нии: обе его обмотки 2 W. 3 включены согласованно и удерживают корь реле прит нутым.The relay / in the normal mode is in working condition: both its windings are 2 W. 3 are switched on consistently and keep the relay clamped.
На внутренней поверхности сигнального флажка 9 (фиг. 2) выполнен клиновой упор 10, за который флажок, при прит нутом коре.On the inner surface of the signal flag 9 (Fig. 2) there is a wedge stop 10, for which the flag, with the bark turned on.
удерживаетс в подн том положении стопорпым зубцом //, укрепленном на коре.held in a raised position with a fixed tooth // attached to the cortex.
При обрыве цепи любого из трех контролируемых проводов, корь реле отпадает, флажок падает вниз и замыкаюте блок-контакты 12 (фиг. 1) реле, обеспечива сигнализацию неисправности цепей.When the circuit of any of the three monitored wires is broken, the relay’s measles disappears, the flag drops down and the auxiliary contacts 12 (Fig. 1) of the relay are closed, providing signaling of circuit failure.
После устранепи неисправности, корь реле прит гиваетс , выпавший флажок поднимаетс персоналом вручную, и схема готова к действию.After the malfunction has been rectified, the relay is thrown into the relay, the raised flag is raised manually by the staff and the circuit is ready for action.
