Description
Предложение относитс к способу резервировани источников посто нного напр жени с помощью реле, обмотки которых включены между источниками напр жени . Такой способ не обеспечивает высокой стабильности напр жени и надежность работы устройства. С целью обеспечени точности выходного напр жени , автор предлагает примен ть три источника напр жени с включением между каждыми двум из них обмоток реле. К общей выходной точке напр жени через нормально замкнутые контакты указанных реле подключены средние точки делителей, включенных параллельно обмоткам реле.The proposal relates to a method of reserving sources of constant voltage by means of relays, the windings of which are connected between sources of voltage. This method does not provide high voltage stability and reliability of the device. In order to ensure the accuracy of the output voltage, the author proposes to apply three voltage sources with the inclusion of relay windings between each two of them. To the common output point of the voltage, through the normally closed contacts of the indicated relays are connected the middle points of the dividers connected in parallel to the relay windings.
На чертеже показана электрическа схема устройства по данному способуУстройство состоит из трех источников напр жени U, Uz и (Уз, подключенных к общей точке через усередн ющие делители, на сопротивлени х R, Rz и 3. включенные между двум источниками напр жени - Параллельно каждому делителю включены измерительные реле PI, PZ и РЗ, которые могут быть пол ризованными как более чувствительныеВ случае изменени источника, напр жени , например U2, на недопустимую величину в сторону увеличени или уменьщени , срабатывают реле PI и PZ к общей точке подключаютс только два источника напр жени i и f/s тогда выходное напр жение is,.,- будетThe drawing shows the electrical circuit of the device according to this method. The device consists of three voltage sources U, Uz and (Uz connected to a common point through the middle dividers on the resistances R, Rz and 3. connected between two voltage sources - Parallel to each divider The measuring relays PI, PZ and P3 are turned on, which can be polarized as more sensitive. In the event of a source change, such as U2, the voltage is inadmissible upward or downward, the PI and PZ relays to the common point odklyuchayuts only two voltage source i and f / s then the output voltage is,, -. be
равно среднему арифметическому напр жению .,,v 9equal to arithmetic average voltage. ,, v 9
Таким образом, помимо автоматического отключени источника з результате у-меньщени или увеличени его напр жени , устройство усредн ет значение напр жени включенных источников, наход пшхс в пределах допусков,- и тем самым повьпиает точность выходного папр Thus, in addition to automatically disconnecting the source due to decreasing or increasing its voltage, the device averages the value of the voltage of the included sources that is found to be within tolerances — and thus increases the accuracy of the output voltage.
