Double-ammeter type watt-hour meter

Abstract

The invention discloses a double-ammeter type watt-hour meter, which consists of two card-inserting type watt-hour meters (1), a timing device (2), an ammeter converting device (3), a low-price ammeter (4), a parity ammeter (5), ammeter cards (6) and card inserting slots (7). The used card-inserting type watt-hour meters are made into double ammeters; and the double-ammeter type watt-hour meter (1) is the watt-hour meter (1) with the charging card inserting slots (7); and the card-inserting type watt-hour meter (1) comprises the two meters (1) which are made into a whole. The double-ammeter type watt-hour meter (1) is provided with the timing device (2) and the ammeter converting device (3). The double-ammeter type watt-hour meter (1) has two ammeter cards (6) and adopts two different charging prices.

Description

technical field [0001] The invention relates to a watt-hour meter, in particular to a double-meter type watt-hour meter. Background technique [0002] At present, a large number of watt-hour meters are sold on the counters of large and small electronic shopping malls in various parts of China, but the management of these watt-hour meters has many inconveniences, and the irregular use of watt-hour meters brings people It is not safe, but there is no good solution at present. The current electricity meter can only be plug-in card type, and there is no time for separate electricity consumption. The electricity price is the same 24 hours a day, and the peak electricity consumption has passed at night , but the power plant still generates electricity in the same way, causing a lot of waste. It is necessary to strengthen the improvement of the watt-hour meter. Which method can be used to solve the problem fundamentally? It can solve the management problem of the use of dual-meter...

[0002] At present, a large number of watt-hour meters are sold on the counters of large and small electronic shopping malls in various parts of China, but the management of these watt-hour meters has many inconveniences, and the irregular use of watt-hour meters brings people It is not safe, but there is no good solution at present. The current electricity meter can only be plug-in card type, and there is no time for separate electricity consumption. The electricity price is the same 24 hours a day, and the peak electricity consumption has passed at night , but the power plant still generates electricity in the same way, causing a lot of waste. It is necessary to strengthen the improvement of the watt-hour meter. Which method can be used to solve the problem fundamentally? It can solve the management problem of the use of dual-meter-type watt-hour meters very well, and it is easy to manage the dual-meter-type watt-hour meters that use dual cards. When using them, the peak power consumption at night has passed , Change another card meter to use low-cost electricity. Use this method. The dual-meter used means that one meter uses low-cost electricity, and the other meter uses low-cost electricity. When the electricity is used at night, the electricity consumption peaks during the day Using electricity with parity meters can solve the problem of electricity consumption, which can save a lot of electricity and energy
