Abstract

The invention relates to a low-voltage circuit breaker, and particularly to an Internet of Things based intelligent modular low-voltage circuit breaker and an operating method therefor. The intelligent modular low-voltage circuit breaker comprises a circuit breaker shell, wherein a power supply module, a sensor module, an electromagnetic control mechanism, a contact system and an embedded type control chip are arranged in the circuit breaker shell; and the power supply module is connected with the sensor module and the embedded type control chip separately. According to the Internet of Things based intelligent modular low-voltage circuit breaker and the operating method therefor, the intelligent modular low-voltage circuit breaker is compact in structure, capable of realizing remote automatic control, and capable of improving the operation precision.

Description

technical field [0001] The invention relates to a low-voltage circuit breaker, in particular to an intelligent modular low-voltage circuit breaker based on the Internet of Things and an operating method thereof. Background technique [0002] The circuit breaker is one of the most important switching electrical equipment in the power system. It is mainly used for connecting and breaking lines and protecting various faults in the system. It plays the role of breaking and closing normal lines or The effect of the faulty line. Nowadays, with the development of my country's electric power industry and the sharp increase in electricity consumption, the low-voltage power grid has higher and higher requirements for circuit breakers. Traditional circuit breakers have insufficient detection accuracy for circuits, are not intelligent, and do not have network Problems such as functions and the inability to perform remote monitoring and control have become more and more prominent.
