Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0011] Such as figure 2 As shown, a single-phase electric energy meter sampling circuit of the present invention includes resistors R1, R2, capacitors C1, C2, manganese copper R0, two high-resistance resistors Z1, Z2 and a power transformer T1, two high-resistance resistors Z1 , Z2 is equivalent to a resistor, the resistance value is megohm level, but in fact it is the internal equivalent impedance of the metering chip pin to ground; an input end of the power transformer T1 is connected to the live wire through a live wire, and the live wire grounding; both ends of the manganese copper R0 are connected by live wires; one end of the resistor R1 is connected to one end of the manganese copper R0 through a sampling line, the other end of the resistor R1 is connected to one end of the capacitor C1, and the high resistance resistor One end of Z1 i...
