The invention discloses an intelligent mutual
inductor and a design method of a low-power-consumption working mode of the intelligent mutual
inductor, and the method mainly comprises the following steps: 1, carrying out the low-power-consumption design of an energy taking mode of a PT collection module; 2, performing low-power-consumption design on the energy taking mode of the CT acquisition module; 3, considering the
power consumption of a subsequent circuit of the module and ensuring the requirement of sampling precision, and selecting models of main components MCU and
radio frequency chipsin the subsequent circuit; and 4, carrying out low-power-consumption design on
software while normal work is guaranteed, so as to achieve the effect of reducing the
power consumption of the whole
machine as much as possible, wherein in order to achieve the effect, the design on the
software is mainly reflected in four aspects of
mode switching, data auxiliary updating, function control and low-power-consumption keeping. According to the invention, the collected amplitudes and phases of the
voltage and current output by the two coils are uploaded to the main
station for comparison to judge whether there is abnormal power utilization or not, so that the problem of power stealing can be solved fundamentally. Meanwhile, low-power-consumption design is carried out on the intelligent mutual
inductor from two aspects of
software and hardware, the influence of the acquisition module on the mutual inductor is reduced, and the performance of the mutual inductor is improved.
