Miniature smart circuit breaker and integrated electric energy metering and remote interaction system thereof

Abstract

The invention discloses a miniature smart circuit breaker and an integrated electric energy metering and remote interaction system thereof. A switching power supply module, a master control unit MCU, an automatic reclosing module and a broadband carrier communication module are integrated into a circuit breaker body; after the automatic reclosing module receives a trigger signal of the master control unit MCU or the automatic reclosing module receives a remote opening command signal of a user in an automatic control mode, a drive circuit drives a DC motor to drive a gear drive mechanism to move, and a trip device in the circuit breaker body is pushed to be automatically opened; and the circuit breaker body carries out data communication with a concentrator of a court through the broadband carrier communication module by adopting a power line broadband carrier communication mode. The miniature smart circuit breaker is conducive to improvement of the feasibility and the enthusiasm that a user participates in a power demand side response, reduction of the difference between peak and valley load of a power grid and improvement of the energy-saving level of a residential building, is high in economical efficiency, is suitable for the occasions of power demand side management, contract energy management, building energy consumption management and smart city construction, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of miniature circuit breakers, in particular to a miniature intelligent circuit breaker with integrated electric energy metering and remote interaction functions. Background technique [0002] With the continuous improvement of the level of urbanization in our country, the area of ​​newly built residential buildings in urban and rural areas is nearly 2 billion square meters every year, and the energy consumption of residential buildings cannot be ignored. Renovating the supporting facilities of existing residences, carrying out power demand side management, cultivating users' awareness of energy conservation, and promoting the interaction between supply and demand between users and power supply companies will help reduce energy consumption in residential buildings. Effective Ways. The miniature circuit breaker is a switching device widely used in low-voltage power distribution systems. It is responsible for the monit...
