Problems solved by technology

The penetrating sensor watt-hour meter is a single-household meter, which can only accurately measure the electricity consumption of a single user, and cannot be managed in a unified manner. It also lacks the phase balance, calibration and adjustment functions among multiple users in a unit or a floor.
The meter reading must be performed on a single meter, and it does not have the function of unified meter reading

Embodiment 1

[0028] Such as figure 1 As shown, a main control display unit 2 is provided in the cabinet 1, and the main control display unit 2 is provided with a connection communication unit 5 and a through-type multi-user metering device. The communication unit 5 is provided with a wave stopper 6 which is arranged on the N-phase zero line of the main incoming line 8 of the unit. The penetrating multi-user metering device includes a penetrating unit total metering device and a penetrating household metering device. The output ends of the penetrating unit total metering device and the penetrating household metering device are respectively connected to the input end of the main control display unit 2.

[0029] The main control display unit 2 includes a display device and a processing device. The input end of the processing device is connected to the output end of the penetrating multi-user metering device, the output end of the processing device is connected to the display device, and the comm...

Embodiment 2

[0032] On the basis of embodiment 1, the through-type unit total metering device includes a through-type three-phase AC sampling mechanism 7 and a three-phase metering mechanism 4. The through-type three-phase AC sampling mechanism 7 is installed on the three-phase power line of the unit's main incoming line 8. Above, the output terminal of the penetrating three-phase AC sampling mechanism 7 is connected to the input terminal of the three-phase metering mechanism 4, and the output terminal of the three-phase metering mechanism 4 is connected to the input terminal of the main control display unit.

[0033] The through-type three-phase AC sampling mechanism 7 includes three through-type single-phase AC sampling mechanisms, and the three through-type single-phase AC sampling mechanisms are respectively arranged on the three-phase power line of the unit main inlet 8. Three through-type single-phase AC sampling mechanisms respectively sample and output micro-signals of each phase of th...

Embodiment 3

[0036] On the basis of Example 1 and Example 2, the through-type household metering device includes a through-type user single-phase AC sampling mechanism 3 and a user single-phase metering mechanism 10. The through-type user single-phase AC sampling mechanism 10 is installed at the user’s entrance On the live wire of line 9, the output terminal of the through-type user single-phase AC sampling mechanism 3 is connected to the input terminal of the user single-phase metering mechanism 10, and the output terminal of the user single-phase metering mechanism 10 is connected to the input terminal of the main control display unit 2. The through-type user single-phase AC sampling mechanism collects the power consumption status of each user, and then performs data processing through the user single-phase metering mechanism to obtain the power consumption information of each user of the unit, which is displayed by uploading the main control display unit.

[0037] The through-type user sing...

Abstract

The invention discloses a unit multi-user intelligent electric energy meter box, which belongs to devices for power utilization centralized metering, management and control of multi-user units of communities. The box comprises a box body, and is characterized in that: a master control display unit is arranged in the box body and is provided with connected communication unit and multi-user metering device; power consumption of each user is acquired by the multi-user metering device and information is transmitted into the master control display unit; a signal is calculated by the master control display unit and a result is displayed, so that centralized meter reading, management and control are facilitated; and uploading of data in the master control display unit and state detection signal transmission of a unit master incoming line can be finished by the communication unit. The meter box has the advantages of wide information acquisition, large capacity, reduced loss, energy conservation, material saving, and capabilities of improving measuring accuracy and meter efficiency, simplifying operation, independently checking meters of users, checking meters in turn and continuously and electrically checking meters on line.

Description

Technical field [0001] The invention provides a device for centralized metering, management and control of electricity consumption of multi-user units in a cell, in particular to a multi-unit intelligent electric energy meter box. Background technique [0002] There are multiple households in each unit of each existing building (residential building, office building or shop), and the electricity consumption measurement is generally calculated by one household and one meter. Set up a centralized box on a certain floor of the building, put the electricity meters of each household in it, and enter the three-phase power mains into the box to measure the total power consumption through a total meter, and then use the principle of three-phase balance and phase separation. Connect with the neutral line to form an outgoing line to connect to each user's home line, and the user's electricity consumption is measured through the user's electricity meter. The power supply company or propert...
