Методика синтеза форсированного броневого электромагнита постоянного напряжения с внедряющимся якорем в схеме с балластным резистором

Abstract

The paper considers a new method of synthesis of forced single-winding armored DC electromagnet with a flat pole plunging armature in the scheme with a ballast resistor, which differs by a reciprocal equation added to the design equations. The response, heat, and reciprocal equations are reduced to one equation concerning diameter of the armature. When solving the latter equation we used generalized loading and thermal characteristics gained by means of methods of similarity theory, experimental design, and finite elements. The problem is solved on the assumption of pre-chosen ratio of the magnetic system's basic sizes, prescribed limits of voltage fluctuation of the power supply, the voltage rate of reciprocal movement of the moving-contact assembly of a power-driven electromagnet, reserve coefficient of response and reciprocal voltage, winding aperture occupation ratio, the admissible reheat temperature of the winding, the ambient air temperature, spurious gaps, parameters of the mechanical characteristic.

Рассмотрена новая методика синтеза форсированного однообмоточного броневого электромагнита с втяжным якорем с плоским полюсом в схеме с балластным резистором, отличающаяся тем, что в уравнения проектирования дополнительно введено уравнение возврата. Уравнения срабатывания, нагрева, возврата сведены к одному уравнению относительно диаметра якоря. При решении последнего использованы обобщенные нагрузочные и тепловые характеристики, полученные методами теорий подобия, планирования эксперимента, конечных элементов. Задача решается при предварительно выбранных кратностях основных размеров в магнитной системе, заданных пределах изменения напряжения источника питания, кратности напряжения возврата подвижной системы приводного электромагнита, коэффициентах запаса по напряжению срабатывания и возврата, коэффициенте заполнения обмоточного окна, допустимой температуре нагрева обмотки, известных температурах окружающего воздуха, паразитных зазорах, параметрах механической характеристики.
