Підвищення ефективності експлуатації точкового колійного датчика за рахунок вибору параметрів високочастотного модулятора

Abstract

For the increase of discriminability and exactness of primary transformer positioning, the methodology of the choice of high-frequency modulator parameters has been offered. For this purpose the classic method of a special purpose function optimization with the use of Gesse matrix and method of Мonte Кarlo has been used. The value of rail magnetizing by a hauling current and electromagnets at their load has been experimentally determined. The maximal value of magnetic induction on a railhead is 2 mТl. The models of devices which diminish the electromagnetic field in the area of setting the primary transformers of axes account have been developed.
