In figure: 1 is input end, 2 is step-up transformer, and 3 is step-down transformer
Embodiment
Long distance transmission of electricity analogue means as shown in Figure 1, comprises input end 1, and described input end 1 is connected in parallel to two branch roads, a benchmark branch road and a comparison branch road.Wherein, described benchmark branch road comprises transmission of electricity resistance R 1 and transmission of electricity resistance R 2, reometer A1 and the electrical appliance of series connection.Described benchmark branch road is by boosting, not form the transmission of electricity circuit of high voltage power transmission for simulation, and the electric wire loss resistance during with transmission of electricity resistance R 1 and the 2 simulation transmission of electricity of transmission of electricity resistance R, by the size of current in reometer A1 detection reference branch road.In addition, described relatively branch road comprises step-up transformer 2, transmission of electricity resistance R 3 and transmission of electricity resistance R 4, reometer A2, step-down transformer 3 and the electrical appliance of serial connection successively.Described relatively branch road is for simulation, by boosting, to form the transmission of electricity circuit of high voltage power transmission, first by step-up transformer 2, boost and form high-tension electricity and transmit, and then transfer high-tension electricity to electrical appliance required low tension by step-down transformer 3, by reometer A2, detect the size of current in comparator circuit.During experiment, by comparing the size of reometer A1 and A2, be just readily appreciated that the benefit of high voltage power transmission.
Further, for can more intuitive understanding comparator circuit mesohigh the benefit of transmission of electricity, described benchmark branch road is respectively pilot lamp L1 and pilot lamp L2 with the electrical appliance in branch road relatively, and the bright dark degree by viewing lamp L1 and pilot lamp L2 just can get information about the advantage of high voltage power transmission very much.
Further, in order to understand more clearly the loss of transmission of electricity, the transmission of electricity resistance R 1 in described benchmark branch road and R2 are variohm.Further, what described variohm adopted here is B alloy wire, and described B alloy wire is connected in benchmark branch road by crocodile clip.Can control by crocodile clip the length of B alloy wire access benchmark branch road like this, thereby control the resistance of access benchmark branch road, form variohm.Resistance in access benchmark branch road is different, and the numerical value that the bright dark degree of pilot lamp L1 and reometer A1 detect will change, thereby absolutely proves the impact of transmission of electricity resistance sizes on transmission of electricity process.
Further, step-up transformer 2 and step-down transformer 3 in described relatively branch road are control transformer, and model is BK-100.Because time boost generations high pressure in the transmission of electricity of simulation long distance, safe and reliable for analogue means, employing low pressure is simulated the process of boosting; Owing to having adopted low pressure, if the consumption of transformer self is larger, cannot successfully simulate the advantage of long distance high voltage power transmission, the own loss of BK-100 type control transformer is less, the numerical value that relatively in branch road, reometer A2 detects can be higher, pilot lamp L2 is also brighter, has so just successfully realized the process of low-voltage simulation high pressure.If the transformer autophage adopting is larger, that compares the numerical value that in branch road, reometer A2 detects can be less, pilot lamp L2 is darker, just little with the bright dark degree difference of the numerical value detecting in reometer A1 in reference circuit and pilot lamp L1 like this, cannot simulate and embody the advantage that adopts transformer high-voltage transmission of electricity.
Further, in order to realize the differential loss of different high voltage power transmissions, the input end of the output terminal of described step-up transformer 2 and step-down transformer 3 is respectively arranged with two taps that adapt, and recently meets like this electricity consumption requirement of electrical appliance by the voltage raising and reducing of the tap that adapts.The output terminal of step-up transformer 2 has two taps, and the first tap is connected in parallel into comparison branch road by switch S 2 by switch S 1, the second tap; The sys node of described step-up transformer output terminal switch S 1 and S2 is connected with voltage table V1.The input end of step-down transformer 3 has two taps, and the first tap is connected in parallel into comparison branch road by switch S 4 by switch S 3, the second tap; The sys node of described step-down transformer 3 input end switch is connected with voltage table V2.The boosting of switch S 1 and switch S 3, step-down ratio adapt, and the boosting of switch S 2 and switch S 4, step-down ratio adapt.The switches set adapting by closure (S1 and S3 or S2 and S4), voltage table V1 detects the voltage after boosting, voltage table V2 detects the voltage before step-down, the loss of resistance R 3 and R4 like this can obtain respectively transmitting electricity, again by relatively showing that the loss of the output resistance under different high pressure distinguishes, the advantage of clear simulated high-pressure transmission of electricity again.
Certainly; the utility model also can adopt other applicable variohms; transformer also can adopt the transformer that other own loss are little, and the tap of step-up transformer and step-down transformer can arrange more than three or three, within such conversion all drops on protection domain of the present utility model.
