Embodiment

[0021] The high-voltage electric pulse detection device includes:

[0022] Induction coil 1, a detection circuit connected to the induction coil; a rectifier circuit, a TVS tube, a Zener diode, a capacitor, an optocoupler and a resistor in the detection circuit are sequentially connected in parallel;

[0023] The rectifier circuit 2 isolates the negative half cycle of the oscillating voltage generated by the induction coil, leaving only the positive half cycle to be transmitted to the subsequent circuit; the current limiting resistor R101 connected in series with the rectifier circuit has a resistance value of 30 ohms; the TVS tube and Zener diode D25, When the voltage is too high, it can lead away the high voltage and protect the subsequent circuit. The TVS tube is BV15C; C93 is used for filtering, and the capacity is 0.1uF; the current limiting resistor R102 has a resistance value of 0.3 kΩ; the optocoupler U24 is an optocoupler 6N137, when there is no induced voltage, its p...
