Description

technical field

[0001] The invention relates to an electric energy metering device, in particular to a digital electric energy metering device. Background technique

[0002] The power supply company uses a watt-hour meter to record the electricity consumption and electricity consumption status of the power users, and then the meter reader will fill in the electricity consumption of each user every month, and the power supply company will calculate the power consumption according to the electricity consumption the amount of its electricity bill. This is the general mode of calculating electricity bills for electricity users, but this mode has many disadvantages, such as:

[0003] 1. Traditional watt-hour meters are often placed inside the user, making it difficult to read their electricity consumption data.

[0004] 2. The traditional watt-hour meter relies on the magnetic force formed by the loop current to calculate the electricity consumption by the rotation of the disk ...
