Description
Предметом изобретени вл етс способ повышени точности регистраци момента электрического равновеси (измерительных схем), основанный на использовании трансформаторов с ненасыщающимс магнитоироводом .The subject of the invention is a method for improving the accuracy of recording the moment of electrical equilibrium (measurement circuits), based on the use of non-saturated magnetically transformers.
Известные гальпанометрические и олектроитг1,1с нульнндикаторы, примен емые в автоматических уравновешенных мостах, нотенциометрах и в системах дииамической компенсации, громоздки и нуждаютс в снециальных источниках нитани .The known gallopanometric and electroneg1,1c null indicators used in automatic balanced bridges, nonotentiometers, and diaamic compensation systems are cumbersome and need special optical sources.
Дл осуществлен1г ттредлагаемого способа 11р гмсл етс маптитлый нульиндикатор, свободный от этих недостатков и особенно эффективный нри наличии общего тракта с усилителем и преобразователем, принимающими поочередные слабые сигналы отметок моментов динамического равновеси различных комнеисацнонных схем.For the implementation of the method of 11p, a small index indicator is free from these drawbacks and is especially effective when there is a common path with an amplifier and a converter that accept alternate weak signals of the dynamic equilibrium moments marks of various commanding circuits.
Сущность нзобретени но сн етс ф1гг. 1 и 2.The essence of the invention is not clear. 1 and 2.
На вход трансформатора с ненасыщающимс магннтонроводом подаетс результирующее ианр женне Е -Е, двух напр жений-измер емого и уравновешивающего (мен ющегос по закону пилы.)The input of the transformer with an unsaturated magnet circuit is supplied to the resulting E – E generator, a two voltage measuring and balancing (according to the law of the saw).
Вентильный элемент В (меднозакпсный элемент нлп днод) нрекращает ток через первичттую обмотку после момента KOMiiejicannit (точка пересечени на фиг. 2), вследствие измепен1т нанравлешг уравнительного тока. Посто нное (равномерное) изменение тока, протекающего через первичную обмотку, создаёт соответственное измепёиие магнитного потока в магпнтонроводе, что, в свою очередь, вызывает но нление ступеньки ианр женн во вторичной обмотке. При вторичиом дифференцироэании этой ступеньки известными методами могут быть образованы острые засечкн моментов начала цикла и комнеисации.The valve element B (copper-clamp element nlp dnod) stops the current through the primary winding after the moment KOMiiejicannit (the intersection point in Fig. 2), due to the measurement of the equalizing current. The constant (uniform) change in the current flowing through the primary winding creates a corresponding change in the magnetic flux in the magnetic circuit, which, in turn, causes a new step in the winding of the secondary winding. In the case of the second-hand differentiation of this step by means of known methods, sharp detection of the beginning of the cycle and the roomification can be formed.
