Circuit structure of intelligent residual-current circuit breaker

Abstract

The invention relates to the field of circuit design, in particular to a circuit structure of an intelligent residual-current circuit breaker. The circuit structure of the intelligent residual-current circuit breaker comprises a control chip, a crystal oscillator circuit, an optical coupler circuit, a first circuit, a third circuit, a fourth circuit, a fifth circuit, a sixth circuit, a seventh circuit and a ninth circuit which are connected with one another; by combining the control chip, the crystal oscillator circuit, the optical coupler circuit, the first circuit, the third circuit, the fourth circuit, the fifth circuit, the sixth circuit, the seventh circuit and the ninth circuit which are connected with one another, the circuit structure achieves the following functions of an electric leakage detection and protection function, wherein the leakage current changing conditions in a line are detected by a zero sequence transformer in real time, leakage currents are judged by an electric leakage protection chip, a tripping command is output when the leakage currents reach or exceed an electric leakage protection value, the intelligent residual-current circuit breaker trips through a tripping coil, therefore, the line is broken, and meanwhile fault information is transmitted to an upper computer through communication; an electric energy measuring function.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a circuit structure of an intelligent leakage circuit breaker. Background technique [0002] With the integration of triple network technology, digital information technology can be used to activate any link, and the three aspects of the triple network can realize the sharing and interconnection of information resources through a certain agreement, so as to satisfy people at any time and any place through information association. Apps to facilitate your own life. People's requirements for the quality of life are increasing day by day. In many aspects, they require the home to be intelligent, fully user-centered, so that users can feel the powerful functions brought by technology. [0003] With the rapid development of digital technology and information technology, the interconnection between consumer electronics, communications and computers has broken through the original scope. ...

AI Technical Summary

Problems solved by technology

In the existing technology, in view of the development trend of 3C integration and triple network integration, the existing circuit breakers cannot well realize the information interaction between smart electricity consumption and household appliances in the smart grid, and cannot well complete the indoor communication network. Data format conversion with wide area network (electric power communication network, Internet, broadcasting network, communication network) and two-way transmission of communication data reduce user experience
