Surge interference resisting protector based on electricity meter reading system

The invention discloses a surge interference resisting protector based on an electricity meter reading system. The surge interference resisting protector based on the electricity meter reading system comprises the power input end of the surge interference resisting protector, a power source first-level protection circuit, a common mode and different mode protective circuit, a power source second-level protective circuit and a power output end of the surge interference resisting protector, wherein the power input end of the surge interference resisting protector, the power source first-level protection circuit, the common mode and different mode protective circuit, the power source second-level protective circuit and the power output end of the surge interference resisting protector are connected in sequence. A transformer stored energy absorbing and consuming circuit is further connected between the power source first-level protective circuit and the common mode and different mode protective circuit. The surge interference resisting protector further comprises a signal input end of the surge interference resisting protector, a signal first-level protective circuit, a lag phase-shifting circuit, a signal second-level protective circuit and a signal output end of the surge interference resisting protector, wherein the signal input end of the surge interference resisting protector, the signal first-level protective circuit, the lag phase-shifting circuit, the signal second-level protective circuit and the signal output end of the surge interference resisting protector are connected in sequence. The surge interference resisting protector also comprises a surge equipotential conversion circuit. The surge interference resisting protector based on the electricity meter reading system has the advantage that under the condition that the surge interference resisting protector is not connected to a special standard anti-lightning grounding grid through a grounding line, lightning inductive surges can be reliably discharged.
