Watt controlling and metering device

Abstract

The metering device includes electric energy distribution bus, management and control unit of measuring electric energy at input end, and management and control unit of measuring electric energy at user end. Control unit of measuring electric energy at user end for 1-30 grouped users, central management and control unit of providing functions of display, control, communication and management for users in group are assembled inside a case. The said bus connects the control unit of measuring electric energy at input end, control unit of measuring electric energy at user end for 1-30 grouped users, and central management and control unit.

Description

technical field [0001] The invention relates to a low-voltage power supply management device, in particular to a centralized electric energy control and metering device. Background technique [0002] my country's electricity market and technology are developing rapidly, but management methods are seriously lagging behind, especially issues such as billing, electricity theft prevention, and safe use of electricity have long plagued power network operators and managers. At present, the measurement management of the low-voltage power supply system for residents usually adopts the outdated model of one household, one meter, and manual meter reading. The construction cost is high, the wiring scheme is complicated, the living space of the residents is occupied, and the meter reading work is inefficient and intensive. The distributed power transmission structure established corresponding to this measurement management mode is not conducive to flexible networking and online maintena...

Problems solved by technology

At present, the metering management of residential low-voltage power supply systems usually adopts the outdated model of one household, one meter, and manual meter reading. The construction cost is high, the wiring scheme is complicated, and the living space of residents is occupied, and the meter reading work is inefficient and intensive.

The distributed power transmission structure established corresponding to this metering management mode is not conducive to flexible networking and online maintenance, resulting in unreasonable network structure and high network construction costs

Moreover, this widely used system lacks the necessary technical support for functions that are of great significance for real-time monitoring of power consumption status, timely deployment of power supply and demand, and detection of power theft behavior at any time.

In order to solve the backward meter reading mode, a new type of electric meter with a single-chip microcomputer installed in the existing electric meter to realize functions such as prepaid power supply and remote meter reading has appeared on the market, but this design undoubtedly greatly increases the cost of use and causes economic burden on users , and does not help solve other problems
