The three-phase prepaid electricity meter is an ideal product for reforming the electricity system, realizing the commercialization of electric energy, solving the difficulty of charging and adjusting the load status of the power grid. So what are the basic functions of the three-phase electronic prepaid meter?
1. Adopt gold card engineering IC card to charge in advance to realize one meter and one number; use special imported metering chip, combined with imported single-chip microcomputer and high-precision built-in crystal clock to realize time-sharing metering and prepayment functions;
2. The six-in-one dedicated LED with Chinese characters displays the remaining electricity bill, current and last month total, peak, peak, flat, valley electricity, meter number, area code, date, time, unit price and other parameters; 12 months of historical electricity data can be recorded ; 4 rates for sharp, peak, flat, and valley; 5 sets of rate periods can be set, and each set of rate periods can be set up to 12 periods;
3. According to seasons and holidays, the meter can automatically switch between 5 sets of rate time periods; holidays can be set for 6 time periods; the perfect bayonet protection circuit design can resist various malicious attacks; the meter alarm and overdraft methods can be set , The alarm or overdraft amount can be set.
4. Overload control, overload power and allowable number of overloads can be set; perfect electromagnetic compatibility design and power supply circuit design, with strong electromagnetic compatibility and extremely wide power supply working range; with maximum power charge limit, maximum power supply Electricity fee can be set;
5. In the case of three-phase four-wire, as long as one phase has electricity, the meter can work; when it has three phase meter three-wire, it has the function of phase loss protection. The recorded information is compared and analyzed, and the management system can list users suspected of stealing electricity, so as to focus on inspection and reduce the workload of preventing and checking electricity theft.
