Use and maintenance of single-phase charging control intelligent watt-hour meter

In the single-phase fee-controlled intelligent watt-hour meter, the "total combined active power" and "total combined active power of last month" can be read, and then the electricity consumption of the current month can be obtained by subtraction. However, the host need not worry at all. Single-phase fee-controlled smart watt-hour meter will automatically upload data or the staff will come to read the meter.

Check the watt-hour meter regularly.

Check the watt-hour meter regularly to see whether its surface is damaged, whether there is any random connection inside, whether the switch on the meter box is flexible and whether it will produce noise. In this case, contact relevant maintenance personnel in time to effectively avoid accidents and ensure safety.

Replace the ammeter fuse.

If it is necessary to replace the fuse of the electric meter, ensure that the fuse current is consistent with the current in the loop, and ensure more convenient installation. Moreover, for different power supplies on the control box, it is necessary to distinguish circuits during maintenance, which can effectively prevent short circuit accidents and prolong the service life of the meter.
