Description

Intelligent breaker of Internet of things

Technical Field

The invention belongs to the technical field of electrical equipment, and particularly relates to an Internet of things intelligent circuit breaker.

Background

The earliest circuit breaker in the world, which was produced in 1885, was a combination of a knife top and an overcurrent release. In 1905, an air circuit breaker with a trip release was born. Since 1930, with the advancement of technology, the discovery of the principle of electric arcs and the invention of various arc extinguishing devices gradually formed a mechanism. At the end of the 50 s, electronic trippers are produced due to the rise of electronic elements, and nowadays, intelligent circuit breakers are appeared due to the popularization of single-chip microcomputers.

The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. The circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to the application range, the high-voltage and low-voltage boundary lines are relatively vague, and the circuit breakers above 3kV are generally called high-voltage electric appliances. The circuit breaker can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, and automatically cutting off a circuit when faults such as serious overload, short circuit, undervoltage and the like occur, and the function of the circuit breaker is equivalent to the combination of a fuse type switch, an over-under-heat relay and the like. Furthermore, no parts need to be changed after breaking the fault current. At present, it has been widely used.

Some circuit breakers can not be dangerous when the zero line and the live wire are connected in a wrong way, and some circuit breakers can easily enable a circuit controlled by the circuit breaker to be electrified after the circuit breakers are connected in a wrong way, so that potential safety hazards are very large. Therefore, a breaker with higher safety is needed.
