Sampling circuit of electronic electric energy meter

The invention relates to a sampling circuit of an electronic electric energy meter. The sampling circuit comprises a voltage signal sampling circuit. The voltage signal sampling circuit comprises a voltage sampling input terminal, a voltage sampling output terminal and a voltage anti-interference circuit. The voltage sampling input terminal and the voltage sampling output terminal are respectivelyconnected with the voltage sampling output terminal through a first sampling signal line and a fourth sampling signal line, the voltage anti-interference circuit is arranged between the first sampling signal line and the fourth sampling signal line, and the voltage anti-interference circuit is respectively connected with the voltage sampling input terminal and the voltage sampling output terminalthrough a first sampling signal line and a fourth sampling signal line. The sampling signal lines used for connecting the signal input terminal and the signal output terminal are routed from the outer side of the anti-aliasin
