Intelligent circuit breaker and application method thereof

Abstract

The invention discloses an intelligent circuit breaker and an application method thereof. The intelligent circuit breaker comprises a service control chip, a tripping control chip, two electric quantity acquisition modules and a tripping execution device, wherein the service control chip and the tripping control chip are connected with each other; the service control chip is also connected with the second electrical quantity acquisition module and an external superior system, and is used for sending the electrical quantity acquired by the second electrical quantity acquisition module to the superior system, analyzing a control instruction issued by the superior system and then forwarding the control instruction to the tripping control chip; and the tripping control chip is also connected with the first electrical quantity acquisition module and the tripping execution device, and is used for generating a tripping control instruction for controlling the tripping execution device to act based on the electrical quantity acquired by the first electrical quantity acquisition module and a setting value, and executing the control instruction. The traditional circuit breaker and the electrical quantity acquisition module with the measurement function are integrated and fused, so that the space is saved and the labor cost is reduced.

Description

technical field [0001] The invention relates to the power distribution Internet of things, in particular to an intelligent circuit breaker and an application method thereof. Background technique [0002] The rise of the smart grid has more functional requirements for various types of power equipment in the distribution network. Among them, the low-voltage circuit breaker is an important node for protection and energy distribution in the distribution network, and is an indispensable part of the underlying infrastructure of urban power consumption. component. Existing low-voltage circuit breakers are also called air switchgear, which use traditional methods such as thermal tripping and magnetic tripping to realize protection functions such as circuit load, short circuit, undervoltage and leakage, while existing distribution circuit breakers not only work The mode is single, the calculation of the setting value is complicated, and it does not have the network communication cap...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned defects, the present invention is proposed to provide an intelligent circuit breaker and its application method that solves or at least partly solves the technical problems that the low-voltage circuit breaker has a single working mode and does not have network communication capabilities or only has local communication functions.
