| Zusammenfassung: | The present invention provides a wide range high voltage sampling clamping protection circuit, including: at least two stages of series voltage detection signal circuits. Each stage voltage detectionsignal circuit includes a signal input end, a signal output end, a plurality of voltage dividing clamping components, and a plurality of voltage clamping portions. The plurality of voltage dividing clamping components are sequentially connected between the signal input end and the signal output end of each voltage detection signal circuit. The voltage dividing clamping component includes a resistor and a voltage clamping connection end, and the resistor and the voltage clamping connection end are sequentially connected in a direction from the signal input end to the signal output end. One voltage clamping portion is respectively connected between corresponding voltage clamping connection ends in the voltage dividing clamping components sequentially corresponding to the adjacent two stagesof voltage detection signa |
