Abstract: Изобретение относится к электротехнике, в частности к релейной защите, и может быть использовано для обнаружения межвитковых замыканий в обмотках трехфазных трансформаторов. Сущность: одну обмотку трехфазного трансформатора используют в качестве питающей обмотки, к которой подключают источник переменного напряжения с известными характеристиками. Две другие обмотки, имеющие одно номинальное значение напряжения, используют в качестве измерительных обмоток для обнаружения в данных обмотках наличия витковых замыканий. Измерительные обмотки трехфазного трансформатора соединяют таким образом, что магнитные потоки в сердечниках измерительных обмоток, создаваемые током в питающей обмотке, направлены в одном направлении. Начала измерительных обмоток соединяют вместе. Два конца двух измерительных обмоток соединяют соответственно с двумя входами датчика переменного напряжения либо тока. При этом выход датчика переменного тока соединяют с точкой соединения двух измерительных обмоток. По показаниям датчика по сравнению с известными значениями напряжения источника переменного напряжения судят о наличии или отсутствии витковых замыканий в измерительных обмотках. 2 ил.

Abstract: FIELD: rocket engines.SUBSTANCE: invention relates to the rocket and space field, particularly to liquid-propellant rocket engines (LRE), and is intended for construction of a mathematical model of a specific instance of the engine used in repeat firing tests. The method is based on using the current values of the parameters of the liquid-propellant engine measured during the firing test and the mathematical model of the processes in form of a system of equations. The essence of the method is as follows. The measured values of the parameters and additional parameters, coefficients, are entered into the mathematical model, wherein each of the parameters is separately included in one of the equations describing the characteristics of the engine accessories obtained during autonomous tests, the hydraulic characteristics of the pipes and the characteristics of the operating processes. The number of such parameters must coincide with the number of measured parameters of the model, in addition to the six parameters at the engine intake: the positions of the drives of the traction control accessories and the ratio of the fuel components, the pressures and the fuel component temperatures. Having solved the system of equations of the mathematical model obtained thereby on every stage of the firing test, the expected values of correction coefficients are determined, wherein the values are then approximated for all modes in form of dependences on the parameters at the engine intake and the approximation dependences are entered into the mathematical model.EFFECT: achievement of the level of accuracy of estimates necessary for accurate calculated simulation of the firing engine in various operating conditions thereof and, ultimately, for replacing some of the full scale tests with calculated studies.1 cl
