When the external voltage exceeds the gas insulation strength, for example, when lightning weather is encountered, the insulation state is switched to the discharge state, and at this time, the second common mode protection module 300 discharges the instantaneous spike voltage to the ground through the second discharge tube GD2. The second common mode protection module 300 can absorb the 6KV zero line common mode surge by selecting the third varistor VR3, so as to clamp the surge voltage to the safe voltage range.
In some embodiments, the second differential mode protection module 400 includes a third winding resistor WR3, a fourth sub-resistor VR4, and a fourth winding resistor WR4.

The third and fourth winding resistors WR3 and WR4 divide the power supply signal passing through the first differential mode protection module 100 to perform a buffering function. The specific resistance value of the fourth sub-resistor VR4 can be adaptively selected according to the magnitude of the power supply signal, and when the instantaneous pulse of the power supply signal passing through the first differential mode protection module 100 exceeds the rated value of the voltages at two ends of the fourth sub-resistor VR4, the fourth sub-resistor VR4 clamps the power supply signal to ensure that the voltage acting on the rear-stage circuit is within the working voltage range of the rear-stage circuit.

It is understood that each of the first sub-resistor VR1, the second sub-resistor VR2, the third sub-resistor VR3 and the fourth sub-resistor VR4 may include a plurality of resistors connected in series, that is, the first sub-resistor VR1 may be composed of a plurality of resistors connected in series, which is not specifically limited in this embodiment of the present application.
