[0017] 2. The electricity metering system uses a positioning mechanism. When the two first articulated frames move toward each other, they will drive the second guide rod to move toward each other.

The position of the electricity metering device in the box can be adjusted through the relative movement of the two positioning plates, thereby ensuring that the heat dissipation gasket can completely fit the top of the electricity metering device.

[0018] 3. The electricity metering system places the dustproof net in the fixed frame through the heat dissipation mechanism and fixes it with bolts. Then the fan is started and the rotation of the fan blades in the fan discharges the outside air into the box through the ventilation grooves. The air is discharged through the holes on the front of the box cover. In the process, the circulation of air will take away the heat generated by the operation of the electricity metering device, thereby completing the heat dissipation of the electricity metering device.
