Three-wire type double-ammeter type watt-hour meter

Abstract

The invention discloses a three-wire type double-ammeter type watt-hour meter which consists of two card-type watt-hour meters (1), a timing device (2), an electromagnetic valve conversion device (3),a low-price ammeter (4), a fair price ammeter (5), ammeter cards (6) and a card slot (7). A used card-type watt-hour meter is made into a three-wire type double-ammeter type watt-hour meter (1); thethree-wire type double-ammeter type watt-hour meter (1) is an ammeter (1) with the charging card slot (7); the card-type watt-hour meters (1) are formed by integrating two meters (1); the three-wire type double-ammeter type watt-hour meter is provided with the timing device (2); the three-wire type double-ammeter type of the three-wire type double-ammeter type watt-hour meter refers to three wiresincluding two live wires (8) and one zero line (9); and the three-wire type double-ammeter type watt-hour meter (1) uses two ammeter cards (6) with two different charging electricity prices.

Description

Technical field [0001] The invention relates to an watt-hour meter, in particular to a three-wire double-meter type watt-hour meter. Background technique [0002] Nowadays, there are a large number of watt-hour meters sold on the counters in electronic shopping malls all over China, but the management of these watt-hour meters has many inconveniences. The irregular use of watt-hour meters brings people It is not safe, but there is no good way. The current electricity meter can only be plug-in type, there is no separate electricity time, 24 hours a day is a kind of electricity price, and the peak of electricity consumption at night has passed. , But the power plant is still generating electricity, causing a lot of waste. It is necessary to strengthen the improvement of the watt-hour meter. Which method can be used to fundamentally solve the problem? If the watt-hour meter is equipped with a three-wire type with dual cards The dual-meter type watt-hour meter can well solve the man...

Problems solved by technology

[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 watt-hour meter can only be a plug-in card type, and there is no separate time for electricity consumption. The electricity price is the same 24 hours a day, and the peak of 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? If a three-wire type with dual cards is installed on the watt-hour meter The dual-meter type watt-hour meter can well solve the management problem of the use of the three-wire dual-meter type watt-hour meter, and it is easy to manage the three-wire dual-meter type watt-hour meter using dual cards. After the peak of electricity consumption at night has passed, use another card meter to use low-cost electricity. Use this method. Using double meters means that one meter uses low-cost electricity, and the other meter uses low-cost electricity. At night, use low-cost electricity. During the peak hours of electricity consumption during the day, using a parity meter can solve the problem of electricity consumption, and can save a lot of electricity and energy
