Intelligent weigh box and application thereof

Abstract

The invention relates to the field of low-voltage power supply facilities, in particular to an intelligent weigh box and application thereof. The intelligent weigh box comprises a box body which internally comprises left and right cavity body space, and is characterized in that an intelligent phase-change switch, a distributing terminal, a double switch A and a double switch B are successively arranged on the left side cavity body of the box body from top to bottom; a plurality of electric energy meters are successively arranged on the right side cavity body of the box body from top to bottom;a load line is in series connection among the intelligent phase-change switch, the distributing terminal, the double switch A and the electric energy meters, the electric energy meters are connectedwith a user through the double switch B, and each electric energy meter is connected with the intelligent phase-change switch through an electric energy pulse signal line. The intelligent weigh box integrates a three-phase equilibrium function, an electricity larceny prevention function and a marketing and power distribution information integrated monitor function and is suitable for rural powernetwork transformation and urban electric network upgrade, the product intelligence degree is high, the weigh box is provided with telecommunication and control functions, and the marketing and powerdistribution integrated management can be achieved.

Description

(1) Technical field [0001] The invention relates to the field of low-voltage power supply facilities, in particular to an intelligent metering box and its application. (2) Background technology [0002] Within the scope of low-voltage power grid distribution business, three-phase imbalances in the power grid are common, and power theft by users also occurs from time to time. The power marketing and power distribution business cannot agree to control. The existence of these three phenomena has caused low power quality in the power grid, The power loss is relatively high, and the cost of power distribution management remains high. Therefore, in the process of operating and distributing electricity, the power sector should try to achieve the three-phase balance of the power grid, prevent the occurrence of power theft, and realize the integrated management of operating and distributing electricity. One of the means of management intelligence and automation. (3) Contents of th...
