 A prepayment meter is a meter with a prepayment feature. A shunt is a small mechanical device that is connected to a meter's reading system. It is used to read and write the amount of money that a customer has paid to an electric company. Generally, the shunt is made of stainless steel or another suitable alloy.
Existing electronic prepayment electric energy meters are single-phase and do not have a mainboard. Their mainboards are connected by wire, and this causes a leakage field in the power transformer 3. In addition, the electric energy meter joins multiple surface-mount elements to a deck plate. The deck plate is a complicated component to produce, which adds significant man-hours to the process. In addition, the production of the deck plate requires paster processing, which adds to the labor cost.
A single-phase electronic prepayment electric energy meter has a mainboard, sample circuit, control circuit, and display circuit. The meter includes surface-mount elements and a shunt welding of current. The mainboard includes a deck plate, which incorporates an electric energy meter card seat plate to transmit information to the prepayment meter's mainboard. The mainboard is composed of a shunt board and a relay.
