变电所开关柜无线测温方案

　　变电所开关柜无线测温方案Working principle: according to the designed induction coil, the device is selected by various design parameters. The product adopts D1 for half-wave rectification, and the protection circuit adopts transient state. The parameters are selected according to the maximum input voltage U2max. C3 electrolytic capacitor for filtering, voltage regulator chip using NCP551-3.3V, the chip input voltage is 12V, static current 0.4UA is very suitable for micro power circuit. Output 3.3V to supply power to the microcontroller. C1 selects large-capacity solid state capacitor, which is particularly important. The advantages of selecting solid state capacitor are as follows: when the microcontroller changes from low power consumption state to full load state, the instantaneous switching of such microcontroller (generally less than 5ms) requires a large amount of energy from the capacitor in the power supply circuit. At this point, the high speed charge-discharge characteristics of solid state capacitor can output peak current in an instant to ensure sufficient power supply and ensure the stable operation of the entire circuit.

　　Coil turns design To establish a simplified model for induction power retrieval, theoretical analysis. Assumption of induction electric primary coil and secondary coil to whole coupling electromagnetic induction, and do not consider the leakage inductance of the primary coil and secondary coil, simplified model to establish induction electric induction electric device work in ideal state, should be busbar current half a cycle, the magnetic induction intensity increased from negative saturation to is saturated, can achieve high power at this time, That is, the output voltage is U2max. When the induction charging device works in an ideal state, it should be within half a cycle of the bus current, the magnetic induction intensity of the iron core increases from negative saturation to positive saturation, and the high power can be obtained at this time, that is, the maximum output voltage U2max.
