Description

Technical Field

[0001] The utility model relates to the technical field of electric energy metering, in particular to a direct access prepaid electric meter. Background Art

[0002] The three-phase prepaid energy meter is a new type of energy meter with prepayment function. Compared with the traditional energy meter, it not only has higher accuracy and better performance, but also can save users a lot of time and cost.

[0003] The three-phase prepaid energy meter is a digital energy meter consisting of a central processor and related circuits. After the user purchases a certain amount of electricity, the central processor in the energy meter will calculate and display the user's electricity consumption and balance based on the preset electricity price and electricity. When the user's balance is insufficient, the energy meter will automatically power off and wait for the user to replenish it. When the user replenishes it, the energy meter will restart and provide electricity.

[0004] Prepaid watt-hour meter is also called quantitative watt-hour meter and IC card watt-hour meter. In addition to the metering function of ordinary watt-hour meter, the special thing is that users have to buy electricity first before they can use it. If the user does not continue to buy electricity after using up the electricity, the power supply will be automatically cut off and stopped. It is used to measure the AC single-phase active power with a rated frequency of 50Hz, and realize the management function of paying first and then using electricity. It adopts advanced microelectronic technology for data collection, processing and storage, and uses radio frequency cards to transmit data. Its performance indicators meet the standards of GB / T17215-2002 and GB / T18460.3-2001. It has the characteristics of small size, high safety, high reliability, and anti-theft of electricity.

[0005] The existing direct access prepaid electricity meter is installed inside the electric cabinet and is installed using a base and a junction box corresponding to the circuit, but it cannot prevent the output terminal and the junction box from being in the same plane, causing the main board and the output terminal to contact the bottom surface, and is easily damaged, making the meter difficult to install.
