Description
При электромагнитном методе измерени течений на ходу корабл возникают значительные затруднени , св занные со сложностью учета коэффициента пропорциональности К между э.д.с., индуктируемой между движущимис в морской воде электродами электромагнитного измерител течений, и напр жением, измер емым указанным прибором. Этот коэффициент измен етс от гидрологических и других факторов.In the electromagnetic method of measuring currents in the course of ships, considerable difficulties arise due to the difficulty of accounting for the proportionality coefficient K between the emf induced by the electrodes of the electromagnetic current meter moving in seawater and the voltage measured by the indicated device. This coefficient varies from hydrological and other factors.
Предлагаемый способ позвол ет устранить указанный недостаток и определить коэффициент пропорциональности К по однократным измерени м напр жени и тока в цепи проводник - электроды.The proposed method makes it possible to eliminate this drawback and determine the proportionality coefficient K by a single measurement of voltage and current in the conductor-electrodes circuit.
Дл этой цели измер ют напр жение, действующее в цепи проводник - электроды, при разомкнутом ее состо нии, а затем - ток с помощью измерител тока, шунтирующего при включении измеритель напр жени . По измеренным параметрам вычисл ют коэффициент К как частное от делени сопротивлени участка морской воды между электродами на величину, равную удвоенной величине сопротивлени электродов плюс сопротивление того же участка воды минус отнощение измеренного напр жени к току.For this purpose, the voltage acting in the conductor-electrodes circuit is measured when its condition is open, and then the current is measured with a current meter shunting the voltage meter when it is turned on. From the measured parameters, the coefficient K is calculated as the quotient of dividing the resistance of the seawater section between the electrodes by an amount equal to twice the resistance of the electrodes plus the resistance of the same portion of the water minus the ratio of the measured voltage to the current.
На чертеже изображена эквивалентна схема электрической цепи проводник-электроды, иллюстрирующа возможность определени коэффициента /С по предлагаемому способу.The drawing shows the equivalent conductor-electrode circuit diagram illustrating the possibility of determining the coefficient A with the proposed method.
Согласно предлагаемому способу при измерени х определ ют ток в цепи проводник - электроды при сопротивлении измерительной цепи напр жение в этой же цепи при г,- При этом сопротивление электродов г и сопротивление участка воды между электродами Го считаютс известными.According to the proposed method, when measuring, the current in the conductor-electrode circuit is determined at the resistance of the measuring circuit, the voltage in the same circuit at r, - The resistance of the electrodes g and the resistance of the section of water between the Go electrodes are considered known.
Зна ток, напр женней параметры г и Го, можно определить R-сопротивление пути тока через неподвижные слои воды и провод щее дно,Significantly, the parameters r and Go are more intense, it is possible to determine the R-resistance of the current path through the fixed layers of water and the conductive bottom,
